The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that while driving 60 MPH, there was an abnormal sound coming from the engine compartment, and the oil pressure gauge dropped. The vehicle was steered to the side of the road, where it stalled. The vehicle was not able to restart. The vehicle was towed to the dealer, but was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 12,794.

Truck has 7000 miles defective valve body failure would not go into reverse and in limp went to dealership and diagnosis is needs valve body replacement with parts on back order with no eta. They said it could be 3-5 months. This is a national issue I’m on multiple social media sites for Chevy trail boss and there is too many to count and it’s been happening since 2021. GM has been no help no loaners and you have to pay for a rental for 3-5 months and pay your truck payments and hopes you are reimbursed at the end. They just recalled the 2021-2022 same 10spd transmissions they are selling Trucks knowing these issues exist also the lifter issues with total engine failures at 10000 miles. The transmission lock up at high speeds.

The truck suddenly and completely shut down while I was driving on the highway, with no warning signs before the total power loss. This unexpected failure put me in a dangerous situation. The vehicle had to be towed to the dealership where it was purchased, and after inspection, the dealer informed me that the engine had completely failed and now requires a full replacement.

Transmission pauses from 1st and 2nd gear. Causing to have no acceleration from a stop. Can cause safety issue to accelerate while pulling in front of traffic. Truck has been to the dealer. Dealer says no codes triggered but the pausing still persists and is only getting worse. Truck has been doing it since around 30,000 miles. Truck currently has 36,760 miles.

I had a engine failure in my 2024 Chevy Silverrado Trail Boss1500. I had just exited off the highway and came to a complete stop at the stoplight. When the light turned green, I hit the gas pedal and I did not move. I looked down at my gear shifter and noticed the truck was in park (I did not shift the truck into park). I tried to put the truck into drive and realized the engine was not running. I tried starting the truck and it would not start. The truck would crank, but would not start up. I tried this several times with no luck getting truck started. I even tried to put the truck in neutral to get the truck out of the middle of the road and could not get it neutral to move it. I called chevy roadside to tow it to the dealer. The dealership called me on tuesday and said the engine had blown because of a bearing failure and engine needs replaced. Also, they have not let me know approx time I will get my truck back. They claim there's a shortages of engines on the 6.2 liter engine.

On [XXX], I [XXX] ) experienced the following issues with my new 2024, Chevrolet Silverado - 1500: • Front Windshield Wiper Washer Fluid not spraying/dispensing. • No messages or symbols displayed on the Driver Information Center dashboard indicating Windshield Wiper Washer Fluid Reservoir low/empty. • Inspected the reservoir that holds the fluid and did not observe low/empty. • Took it to the GM dealer 4 times and they were unable to repair. My vehicle has a recurring defect with the windshield washer system where the washer fluid does not dispense when activated. This issue occurred on a new vehicle and has persisted despite service attempts. When the washer fluid fails to spray, I am unable to clear dirt, dust, road debris, or moisture from the windshield while driving. This significantly reduces forward visibility, especially at freeway speeds or in conditions where debris from other vehicles hits the windshield. The inability to clear the windshield immediately creates a safety hazard because it can obstruct the driver’s line of sight and increase the risk of a collision. This issue is not cosmetic, it directly affects safe operation of the vehicle and the driver’s ability to maintain visibility during normal driving conditions. I am reporting this because the defect is ongoing and may affect other vehicles of the same model. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

It happened to me twice but the first time I was driving on the highway with my family and without warning my engine cut off and I had a message that said “press start button to restart”. I coasted to the shoulder, put the truck in park, and was able to restart. I took it to my dealership where they ran codes and nothing wrong with the engine showed. About 2 weeks later I was taking my kids to daycare and had just exited the highway when my engine cut out again. I pulled up to the 4 way stop sign intersection and tried to restart the truck but it was completely dead and I was stranded in the middle of the intersection with my 3 and 1 year old. The truck threw an engine light this time. I tried to get the truck out of the intersection but the gear was stuck in park and wouldn’t shift to neutral. I then had the truck towed to my dealership where it has been since.

No warning vehicle has dead battery and first message that appears is ‘Service Steering Column Lock’. Cannot reset.

While driving on March 23, 2025, we heard a loud bang, we stopped at a gas station shortly thereafter and realized the tailgate had fallen open while driving and struck the trailer hitch. The latch/camera compartment were broken and hanging from where it struck the crank for trailer hitch and the tailgate was damaged (dented). It was taken to the dealership where they advised there is a recall on some models due to this same issue. They checked and advised our truck is not part of recall. We filed a PAC claim with Chevrolet which they are declining to pay. The latch/camera is currently taped into place. It has fallen open while driving one additional time since the first event. We frequently carry things in the bed of truck and our safety and that of anyone behind us could be in jeopardy.

Vehicle does not indicate proper DEF level. Vehicle has stated several times that it is out of DEF but is not. The most recent time the vehicle was at a dealer and was noted as normal operation. Driving up to going the dealer: vehicle displayed message “DEF empty refill now vehicle speed restricted to 65mph”with a 500 mile count down. Vehicle was driven 489 miles of the 500 miles. Vehicle was taken to a dealer. Dealer confirmed that vehicle was not out of DEF, vehicle was at 40% DEF capacity (~2 gallons of fluid in a 5 gallon tank). Dealer noted that this was normal operation. This is not safe, the DEF system isn’t accurately reporting level. In other situations it hasn’t recognize DEF fills. This can potentially lead to the vehicle severely restricting speed or not allowing the motor to restart creating unsafe conditions for the passengers and other vehicles on the road way. Vehicle was under warranty at the time of the issues. Vehicle is currently just under 37,000 miles.

Was pulling out onto the road from sitting at a traffic light, vehicle was going less than 25mph when the engine made a clunk trying to shift and the check engine light came on. Computer software indicated “limp mode with reduced acceleration activated.” Vehicle wouldn’t accelerate above 35mph, had to drive on major highway to get to dealership. Truck is only used as commuter vehicle hasn’t towed anything. Dealership indicated valve body transmission failed with vehicle only have 9k miles on it. Part is on back order as it is being manufactured due to installed faulty part, problem has been going on in 2023/2024 Chevy and gmc trucks since January 2024 without a recall put in place. Problem is being fixed after the part fails and the truck fails to run at optimal valves. According to forums software update were installed versus recalls to the actually valve body part being. I was sold a truck in sept 2024 with a faulty installed part versus it being fixed before it was purchased. This caused me to be stranded 1500 miles away from my home and we were not made aware of the know valve body transmission issue. The information was covered up versus being disclosed.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated while driving 55 MPH on a highway entrance ramp, the vehicle failed to accelerate upon depression of the accelerator pedal. The contact stated that the "Reduce Acceleration Drive with Care" message was displayed on the instrument panel. The dealer was notified of the failure and the contact was instructed to take the vehicle in for a diagnostic test. Once the contact arrived at the dealer, 13 diagnostic trouble codes were retrieved; however, the dealer could not duplicate the failure. An appointment was scheduled with the same dealer, and it was discovered that the diesel particulate filter was clogged with soot, causing the vehicle to enter LIMP Mode. Despite this discovery, the dealer was unable to duplicate the failure after the filter was unclogged. The vehicle resumed normal operation. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was 11,267.

Truck will randomly throw codes for service 4wd and forward collision unavailable, rear cross traffic unavailable, lane departure will not work, auto high beams not work, and if parked position truck will not release Park brake making truck unable to be moved. Truck has been in and out of certified dealer 3 times and problems still occurring at random. Dealer has stated they are not able to duplicate issues and can't do anything. Issues happening pose risk while driving when codes come on making all standard safety features not to work in event of a accident.

Vehicle has left me stranded multiple times, once over 2000 miles from home at only 26k miles on the vehicle with catastrophic engine emissions and electrical failures. Costing me thousands in lodging and months of my time. My vehicle has stalled multiple times on interstates and busy roads with no shoulders putting me and other drivers at risk.

I’ve had 3 occasions of this brand new vehicles front collision avoidance system going off HARD and locking up the brakes. It scared the crap out of me as there was nothing in front of me - if I hadn’t known the truck had automatic collision software - I’d have driven to the Chevy Dealership right then. The first time I thought it was a fluke. The second time it really caught me off guard. The third time (inside 2 months) I realized there is something not right. I reported it to the dealership but they wanted me to trade it in for a new truck. Sorry, no. I just want to report this problem as I’ve seen a recall on other vehicles with 10 speed transmissions.

My name is [XXX] and I currently own a 2024 Chevy Silverado 1500 ZR2 Truck with a 6.2 lt motor. On [XXX], my truck failed me at which point it had to be towed by road side assistance to Sun Chevy in Chittenango NY. While at the dealer I was advised that my Truck engine 6.2 is bad that the crank shaft bearing failed and further piston rods failed and it would need to be replaced. Two days following I received a call and was advised by the dealer (Sun Chevy) that GM advised the dealer to rebuild the engine. Once that was completed 10 days later the dealer contacted me and stated that the motor does not sound right and there were further problems. I was also advised by the dealer that this is a known problem with 6.2 motors and GM is aware of it. On (3-14-2025) I was told by Sun Chevy that the 6.2 motors are on backorder and I would have to wait approx 6 to 9 months. This truck is not even 1 year old and this is not acceptable in any way. I am paying on a truck that is not operable. I have always been a faithful Chevy owner however I cannot wait this long after buying a New Truck. I called GM to discuss options moving forward and them replacing my Truck. I can be contacted at [XXX], or [XXX]. According to GM This issue has been assigned a case number and that as far as it has gone. My famiky vacation now has to be cancelled as we were going to be traveling in the Truck and the Dealer stated that the loaner vehicle cannot leave the state. This is a complete mess.

I was driving on [XXX] leaving from Onawa, IA. Up to this point I had not issue or notifications about my vehicle. While driving North bout and having the adaptive cruise control set at 80 MPH, I was in the left lane passing 3 semis in the right lane. After passing the first one, the first semi merged to the left lane following. I was approximately 1/2 passed the next semi when all the sudden my cruise started to slow down. It went from 80 to 78 back to 80, then 80 back to 77 to 80. Suddenly and with no warning the engine completely shut down and I went from 80 - 0 is approx. 100 feet. The semi behind me sounded their horn loudly as they almost hit my rear end before merging over. I had no time to go over to the right shoulder and had to go to the left where the vehicle would not move. I could not move the vehicle off the shoulder as it would not shift to natural. Law enforcement was notified as the safety of the vehicle on the left side of the interstate caused safety issues.

While driving my vehicle on the highway I was exiting when I looked down at the instrument panel it stated a message along the lines of shifting to neutral and to press the ignition to restart engine. I noticed the vehicle wasn’t accelerating when attempting so I slowed down and did what it instructed me to do. The engine then wouldn’t start, I was uneasy because cars were coming from behind at a decent speed because of morning traffic. I somehow managed to get it to crank and took it to the dealer right away. They stated it was from low voltage and were replacing the battery under warranty. I didn’t think that was the cause but gave them the benefit of the doubt. 2 weeks later while taking my family out, the same incident happened. I wasn’t able to get it to crank and had to get it towed to the dealer. They stated it was the engine because now the engine was making a loud sound when ignited. It is about to be 4 weeks without vehicle and no repair has been made due to no inventory on engines.

Reduce Acceleration drive with care and engine light came on. Can’t go faster than 40 MPH and unable to reverse. Only 8,000 plus miles. According to mechanic, it’s a sticky transmission valve and there should be a recall.

Sudden Engine failure, metal shavings found in oil at 16K miles. GM and the dealer acknowledges that the 6.2L motor has been having issues. They state that they are currently investigating but a "fix" of the issue has NOT been made. The motor was replaced under warranty, however, the engine they replaced it with has the same chance of failing as the original engine. There was no warning, no indications prior the the motor seizing up at a red light

Hi - I'm filing a complaint against Chevrolet with the NHTSA's Office of Defects Investigation. I purchased a brand new 2024 Chevrolet Silverado in Dec of 2024 from a dealership in MA. I've had the truck for only 2 months and only a couple thousand miles. I was in Quebec with my family for a ski vacation and we were driving back on [XXX} when my truck suddenly started making loud engine noises. I was able to get off the interstate to a gas station and then the truck turned off and would not start again. I had the truck towed to a Chevrolet dealership in Granby, Quebec. There was no warning or alerts before the engine failed. This is a known issue that the NHTSA is currently investigating, it has to do with the 6.2L V8 engine in GM vehicles from 2019-2024. The engine is seized and cannot be repaired, truck needs a new engine. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When driving at slow speeds, less that 10 MPH, the engine shuts off and vehicle shifts to neutral. Message is displayed on driver console Press Start Button to restart. Only the engines shuts down as all displays, entertainment center and controls are still displayed. Pushing the start button restarts the engine. This has occurred several times since purchasing the truck however it has occurred 2 times in the last 45 days. This issue has happened while driving in slow traffic on the interstate and is concerning when it occurs as I come to a complete stop without warning creating a possible rear end accident. It was first reported to my Chevy service dealer on 2/21.2025, The Chevy tech stated they could not duplicate the issue so no remedy has been offered. The issue continues to happen and I will be returning to my Chevy service center for another report of this continuing to happen.

My truck had a check engine light come on for the transmission 2 months ago and then it went off before it was serviced. They said they couldn’t do anything since the light went off. Then last week I didn’t have reverse and it wouldn’t shift into gear. A week after it had been in the shop they told me the transmission valve body needs to be replaced. Expected date for parts to arrive is 3-10.

My truck has a 6.2 liter engine the engine lost power. I have had the adaptive cruise shut down and start back up with no blockage that would cause it, I have had issues with the radio/GPS around seven or eight times the GPS almost sent me the wrong way on a one way street. the truck is still in the shop

The transmission lost the ability to move the vehicle. The valve body for the transmission became inoperable at 7,600 miles. This is a safety issue because it can leave people stranded in cold/inclement weather. This happened without warning and the dealer replaced a spacer and check balls for the valve.

Date of purchase [XXX]. Date of incident [XXX]. I was on my way to work at [XXX] and it was raining . Truck would not accelerate more than 45 miles an hour speed limit is 65 on the freeway. Engine light turned on and all the dashboard icons turned on. Drove it to the nearest dealership Tom Bell Chevrolet in Redlands Ca. Once I put vehicle in park it would not start. The message on the dashboard board displayed something like unable to access. So I went to see if service center open since it was [XXX]. He instructed me to drive around I said it will be not go into motion. After 15 minutes I checked the status on my phone and it did not display anything wrong so I went ahead and turned it on and drove it to the service center but once again it would not accelerate and shock vigorously. Once in the service line it turned off and did not stay on. Dealership ran diagnostics he mentioned cylinder and piston but they need to run more test. He called me back 2/14/25 asked if I had taken it to the dealership where I bought since purchased I said no it’s brand new, it looks tampered with . Called me back again and said this vehicle had a motor recall and a technician at Riverside Chevy worked on it and all the components are not connected we can work on it it need to go back to them and they need to explain what is wrong. He sent them a video of the tech looking at everything that was wrong. Truck was towed to Riverside Chevrolet [XXX]. This is a brand new vehicle that only had 17 miles when purchased by me ,at the moment it has 709 miles non of the components of this vehicle are new anymore they are either melted or rattling inside ,the gas tank sounded like empty cans rolling around, the transmission would not make the vehicle move.

Total engine failure on interstate in North Carolina

Motor blew in my 2024 Chevy Silverado. Motor was a 6.2 liter, L87 with 17,600 miles. Tomorrow will be 4 weeks without my vehicle. I've gotten no information on when any repairs will be made, nor have I gotten any support from the dealership or GM. I was driving 60+ mph in heavy traffic when the motor went. I was put in a bad situation and was lucky to get out of it without injury. I don't know what to do and need help!

The entire camera safety system is glitchy. Whether backing up or not, the side, front, back and top view camera system intermittently works then doesn’t, going days on end without working.

Driving on interstate 85 on cruise control when I herd the motor RPM start to climb so I tapped the break and that’s when the truck shut itself off and put itself in neutral causing me to have to coast over to shoulder of the road. Message on the dash said push start button to start again. There were no check engine lights, no overheating temperature lights. No codes at all. The truck is a 2024 with 62,000 miles and all oil changes on time. Upon checking online , this has happened to other vehicle owners as well. Apparently the Chevy Silverado with the 6.2 liter engine has problems with push rods and bearings. Some have replaced multiple engines. Chevy wants me to pay for new engine.

While driving on the interstate at 75 MPH, the vehicle lost all motive power. No warning light was illuminated. I pulled over to the right side of the road and attempted to restart the vehicle; however, the vehicle failed to respond as needed. It was -30 degrees outside and it was dark. I had passengers in my vehicle, and we were stuck with no power or heat on the interstate. The vehicle could not be put into neutral to be moved off the interstate because there was the vehicle would not turn on. This was an extremely unsafe and dangerous situation for me and my passengers. The vehicle was towed to the dealer where it was diagnosed and determined that the engine was damaged and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and the contact was informed that the engine was not available for replacement. The vehicle is still at the dealership and has been there for 2 months. The approximate failure mileage was approx. 19,000 miles.

Vehicle defect appears related to recall but dealership is unable to identify without tear down of engine. Previous dealership when first reported non responsive. Manufacturer refusing to further fix and or resolve outstanding safety issue of major safety concern.

Engine check light came on at 10,500 miles and under 300 hours of engine time. Initially thought it was due to a wheel speed sensor failure from the salt and brine build up from winter weather. After having the code ran the engine is misfiring and has a rough idle. This is an L87 6.2L motor on a 2024 Silverado ZR2. After researching this problem it is way more frequent than the total of 39 official reports with a similar truck owned by an acquaintance having the same issue at the same mileage. Engine sound has changed, the truck shudders, and may seize up at any moment. The truck had 1 oil change at 5500 miles and was due for its second oil change at 11500 but will more than likely need an engine replacement.

The contact owns a 2024 Chevrolet Silverado 1500. The contact stated that upon starting the vehicle and attempting to shift into drive(D), the vehicle failed to shift or respond as needed. The contact became aware that the vehicle also failed to shift into reverse(R). After restarting the vehicle, the vehicle returned to normal functionality, and the contacts son was able to shift into drive. The contact stated that while her son was driving 50 MPH, the vehicle briefly accelerated independently before returning to normal functionality. A message to "Please Decelerate and Drive with Caution" was displayed. The check engine warning light was illuminated. The vehicle was towed to an independent mechanic, who diagnosed a failure with the throttle body. The vehicle was not repaired. After investigating the failure, the contact related the failure to Technical Service Bulletin: 24NA181. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was 7,000.

Subject: Engine Failure – 2024 Chevrolet Silverado 1500 (6.2L V8 •VIN: [XXX] Issue Description: While driving on [XXX], I noticed the transmission would downshift but not upshift. Within seconds, a warning appeared: “Oil temperature high, idle engine.” I began merging onto the shoulder, but before I could get there, the engine shut off completely, and the transmission shifted into neutral. After coasting to the shoulder, the transmission shifted into park on its own. Failure to Restart & Electrical Issues: I attempted to restart the engine, but it would not turn over. The dashboard, radio, and electronics turned off for a few seconds before coming back on, but the engine remained unresponsive. Towing Difficulties & Roadside Assistance Failure: GM Roadside Assistance said no contracted towing companies had the equipment to tow my truck because it would not shift into neutral without the engine running. I had to find and pay for a tow truck myself, with no guarantee of reimbursement. Dealer Response & Repair Delays: My truck has been at the dealership for days, but they have not started repairs due to technician shortages and a backlog of work. They stated: •Manually cranking the engine is nearly impossible. •The starter is not strong enough to turn it. •Repairs could take months. Loaner Car & Additional Hardships: Per the GM warranty, I received a loaner car but must return it every 500 miles. Since I commute 160 miles per day, I must frequently exchange it, causing major inconvenience. Safety Concerns & Requested Action: This sudden engine failure on the highway was a significant safety risk. Given that NHTSA is investigating failures of the GM 6.2L V8 (L87), I believe my case is related. GM should issue a recall or extended warranty for affected vehicles.

This is the 3rd engine failure in 23K miles. The first was a Lifter/Rod problem at around 3K miles. The 2nd was catastrophic engine failure due to a spun bearing at 21K miles. Now at 23K miles, I'm having another catastrophic engine failure with the same issue. Engine is the 6.2L L87.

When Driving my 2024 Chevy Silverado with 24,600 Miles on it this morning, i was on the New York State Thruway going highways speed (70MPH) when the truck Lost Power, and Shut completely off, I had a tractor trailer behind me and lucky my pick up truck was able to coast over the white line, if i would have been able to coast over the white line i would have been in a major accident. I attempted to start the truck up again and the truck would not turn over, i had sat there for about 25/30 Min trying to get the truck started and finally the truck turned over and i was able to continue on to work, While driving the truck had absolutely no power and the truck was sitting around 3K RPMs when going 66mph, the truck was hard shifting into gears as well. I arrived at work and i got to a parking space and all the sudden the truck shut off and wouldn't not start back up. Upon arriving to work i rolled down my window and heard a long banging noise coming from the engine Aswell as a whining noise. I attempted to start the truck up and you hit the start button the truck just keeps whining and never starts up. I was able to contact GM Roadside and have a tow truck come and pick the truck up and bring it back to the dealer. Im awaiting the dealer to contact me. Overall, i could have been in serious car accident for because the engine just shut off on the highway, this happened with no warning or anything, the check engine light was NOT on before this happened.

The valve body in my transmission went out in Colorado where my truck is currently at a dealership under warranty. They are putting my job at risk due to the fact that I bought that truck specifically for work since I travel all over the country for work. I told them that I need the part expedited because I need to leave Colorado and go to Texas for work on the 28th and still no help at all. All I’m asking for is for the part or a new transmission to be sent and installed before the month ends. Because if it doesn’t I’ll get fired if I don’t make it to Texas. And I’ll state this I will pay out of my own pocket even though the truck has warranty if it means the part can get expedited.

2024 Chevrolet Silverado 1500 Trail Boss While driving, I was given no notice to the vehicle shutting down, couldn't go forward nor backwards. Barely got off the road, waited hours on rollback. Dealership ran a test, said "control valve body " problem. Part is ordered, on back order. GM - taking software to attempt to monitor when? this problem is going to occur? They know about excessive wear, Why not Re-Engingeer this problem instead of selling vehicles that no one knows when this problem of stopping on the road will occur. That would be a safety issue. A hazardous issue of driving on the road and not know when this would happen. If the vehicle doesn't stop from GM software, the rear wheel brakes lock up.
