2019 Chevrolet Silverado Powertrain & Transmission Problems

"The transmission valve body is failing, causing the rear wheels to violently lock up while Driving

I was driving my 2019 Chevy Silverado TrailBoss with 81,000 miles at 65MPH on I-80 East in Omaha, NE, when 3 warning lights came on. The first was the Service Parking Brake. The second was Service ESC. The final was a flashing Check Engine light. My truck started backfiring/misfiring, making a loud ticking noise, and running extremely rough. I was trying to merge off the interstate, but it was running so rough that it made it very difficult to do so safely. Eventually, I just had to finish going where I was headed and park it in the lot. I did some research and called my local shop. They said to stop driving immediately and have it towed to them for inspection. They used a diagnostic tool and diagnosed the issue as a DFM lifter failure. But they could not fix it there and recommended I take it to a different shop. I had it towed again, and they did their own diagnostics and have the same idea, but without taking the engine completely apart, they can't tell for sure. They want to charge me $1,250.00 to inspect it further. I called the dealer where I purchased the truck back in 2019 and am working with them on next steps. The last shop quoted me $7,800 repair if it is indeed the DFM lifters. Based on what I know, this is a known issue with these trucks. GM has an "Out of Warranty Policy Assistance" in place just for these know lifter issues. This is very concerning that GM hasn't done a recall on these parts as it has shown to be a safety issue when driving the vehicle in traffic on the interstate. I just hope that GM assists me with the repair costs because it is not guaranteed and I cannot afford $7,800 right now.

Third transmission failure in 10 months on this vehicle (8-speed automatic). (1) Oct 2025, 67,885 miles: transmission shuddering; dealer replaced the complete transmission with a GM remanufactured unit under extended warranty (RO 240481, Nucar Lannan Chevrolet of Woburn, MA). (2) Jul 2026, 82,439 miles: vehicle would not shift on the highway while driving; DTC P2824 stored; dealer replaced the transmission valve body under warranty (RO 248929). (3) Aug 3, 2026, approx. 82,500 miles — three days after the valve body repair was returned to me — the transmission locked up and the vehicle would not shift gears while in traffic. Loss of gear engagement while driving creates risk of a crash from sudden loss of propulsion. Vehicle is back at the dealership now for the third repair. This vehicle's 8-speed transmission (8L90/8L45 family) is the subject of known shudder/valve-body defect litigation covering 2015–2019 Silverado models.

Transmission started shuttering on way to work went out before making it home. No problem before this trip.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving, the vehicle failed to exceed 6 MPH. The check engine warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed and it was determined that the ABS module needed to be replaced. The dealer had retrieved DTC: P2074. The vehicle was repaired, but the failure reoccurred. While driving in stop-and-go traffic, the vehicle failed to accelerate and unexpectedly shifted into park(P). The contact stated that the vehicle failed to restart, and the battery was disconnected and reconnected. The vehicle was then taken back to the local dealer, and additional diagnostic tests were recommended. The contact was informed that the torque converter and transmission needed to be replaced. The vehicle was taken to an independent mechanic, who stated that the failure was related to Technical Service Bulletin: 23-NA-018. The manufacturer was contacted and informed that the dealer should use a flow chart. No assistance was provided. The failure mileage was approximately 100,000.

Engine oil cooler line leaking from crimp. Same issue CSP N212326940 GM distributed but my truck was not covered for some reason.

I own a 2019 Chevrolet Silverado 1500 equipped with the 8-speed automatic transmission. The vehicle has developed serious transmission problems that create a safety concern. When the transmission is cold, the vehicle slips between 1st and 2nd gear during acceleration. If I accelerate normally, the transmission slips and then engages with a hard bang. I must accelerate very slowly to avoid harsh engagement. In addition, during deceleration, especially when downshifting into 3rd gear, the transmission makes a hard "thump" or "bang". This unexpected shifting behavior creates a safety risk when entering traffic, making turns, or driving in stop-and-go traffic. The vehicle has been properly maintained, including transmission fluid service at a Chevrolet dealership, but the problem continues and appears to be getting worse. I understand many GM 8-speed transmission owners have reported similar issues. The repair cost quoted by the dealership is between $7,000 and $10,000, which suggests a possible design or manufacturing defect. I am filing this complaint for investigation of a potential safety-related transmission defect.

I have a 2019 Chevrolet High Country, have always kept it serviced and maintained. Driving down the road it randomly lost power, wouldn't let me (driver) give gas, started shaking and making loud clanking noise from the engine. Was able to pull over to the side of the road, recorded the noise it was making. Called a tow company to get it towed to the nearest Chevrolet Dealer ship and they confirmed that the engine was no longer good. Related problem to the 6.2l motor issues. They are requested for a New motor.

I am reporting a potential safety defect involving my 2019 Chevrolet Silverado 1500 Z71 Trail Boss (VIN [XXX]), currently at approximately 63,000 miles. My truck suddenly developed a rough idle, engine ticking, and a cylinder 3 misfire. The check engine, traction control, parking brake, and “Service ESC” warnings appeared. The transmission also began shifting extremely hard, at times feeling as though another vehicle had struck the truck from behind. The oil pressure gauge also stopped functioning. Due to these symptoms, I stopped driving the vehicle. A diagnostic scan produced P0303, P0449, P0498, P0499 and P0500. After replacing a failed cylinder 3 spark plug, the truck initially ran perfectly for approximately 20 minutes before the rough idle and warning lights returned. The vehicle was subsequently diagnosed by a Chevrolet dealership. The dealership determined that the engine suffered a collapsed lifter that damaged the camshaft and other internal engine components. The engine repair estimate is approximately $10,000–$12,000. The dealership has also reported that the transmission is slipping and believes the torque converter/transmission requires approximately another $6,300 in repairs. I am concerned that a lifter/DFM-related failure causing a misfire, rough running and potential loss of engine power could occur while a vehicle is traveling at highway speed and create a significant safety hazard. The severe transmission shifting and subsequent slipping are also concerning because unexpected vehicle behavior during acceleration or while in traffic could increase the risk of a crash. The truck has been regularly maintained and has relatively low mileage for its age. I am requesting that NHTSA review whether similar engine/lifter/DFM and related powertrain failures represent a broader safety defect and whether an investigation or recall is warranted.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at 30 MPH, the rear wheels locked upon depressing the brake pedal without warning. The contact temporarily lost control of the vehicle, and the rear wheels skidded, almost causing a crash. Due to the failure, the vehicle was towed to the residence, where it remained. The dealer was notified of the failure, and the contact was informed that there were no recalls related to the VIN. Upon investigation, the contact discovered NHTSA Campaign Number: 25V148000 (POWER TRAIN); however, upon contacting the dealer, the dealer claimed that there was no knowledge of the recall. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 136,000.

Engine oil cooler line leaks and crimping does not hold hose tight enough and slipped off crimp fitting. line came completely off of crimp fitting and leaked all engine oil. Forced engine to be turned off and low engine oil marked on dash.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while stopped at a stop sign, the vehicle stalled. No warning lights were illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with premature wear in the transmission, and the transmission needed to be replaced. The contact researched and was made aware of an unknown recall; however, the VIN was not under recall. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

"Approximately four months ago, I noticed an oil leak coming from the midsection of the engine/transmission of my 2019 Chevy Silverado LTZ with the 6.2-liter engine. At the same time, I noticed a slight knocking or rattling noise coming from, I believe, the front of the engine. Upon taking it to the dealership, they replaced the engine oil coolant lines, only to find out that the engine was still leaking oil and still making the knocking and rattling noise. They then discovering that it was the rear main seal, they have since replaced it about one week ago. Yesterday, February 6th, about 12:15 pm in the afternoon, while I was getting off the I-405 in Renton Washington and merging onto the southbound lanes of 167. I was in the left lane and I made it about a quarter mile down 167 doing about 60 to 65 miles per hour and I lost power suddenly. As I started to merge into the right lane, I noticed the engine light came on, and then the truck seemed to kick down into first gear while I was doing 50 miles per hour, which instantly slowed it down. This forced me to cross over an on-ramp lane to get to the shoulder and come to a complete stop. After that, the truck would not start at all. I then had to sit on the side of the road for three and a half hours waiting for a tow truck to take me and my truck back to the dealership, which is also the same dealership where I bought the truck back in 2019. They have not diagnosed it yet as I just dropped it off at 4 pm on 2/5/2026. My truck has approximately 155,000 miles on it.

Afm lifters has failed in my vehicle 3 times as of date. Being that its a costly repair this should be recalled. Information provided is the latest mileage.

My 2019 vehicle experienced premature torque converter failure resulting in transmission shuddering, hesitation, and loss of power while driving. The transmission fluid was found to be burnt, and the vehicle requires major transmission repair. These symptoms occurred during normal driving conditions and created a safety concern due to unpredictable vehicle behavior, particularly during acceleration and merging. This issue is widely reported in 2019 vehicles equipped with GM 8-speed transmissions. GM has acknowledged the issue through technical service bulletins but has not issued a recall.

I have a 2019 Chevrolet Silverado 1500 with the 5.3ltr V8. The vehicle has 44,500 miles and has zero accident history. On 01/12/2026, the oil cooler line broke while driving, leaving 8 qts of oil covering the underside of the vehicle (exhaust, suspension and tires) creating a fire hazard along with possible loss of control with the rear tires coated in oil. Additionally, the vehicle is undrivable almost immediately due to zero oil pressure. The local Chevrolet dealership diagnosed it as a oil line failure. There is a Chevrolet Customer service program N212326940 for only certain VIN for this vehicle for this specific problem, however it doesn't cover my vehicle. In reviewing different web forums, this is a commonly known failure point with some defect to the hose clamp. GM has not extended a recall and has stopped covering this known failure. I'm not sure if it's a vendor/supplier failure with the oil line or an installation problem. A full recall and/or 10yr/100k warranty coverage should be provided for all oil line failures due to thousands of prior similar failures with the same oil line.

Power Train available for inspection upon request? Truck came to a full stop while trying too just slow down to merge in to left turn lane, tried to move truck into turn lane but truck struggled to move finally after several attempts the truck moved just enough to get it in our cul-de-sac and then the truck would not move forward or backward. husband had to set in truck to wait on the tow truck to keep traffic from running in to truck, had truck towed to Mark Allen Dealership Mark Allen Chevrolet Dealership was unable to reproduce the Problem by driving truck several days Mark Allen Dealership can better answer this question, I have only taken it to Mark Allen Dealership No warning signs of any kind I do not understand why we have not received a recall on our truck for the transmission locking up unexpectedly like others have been recalled for

While driving the vehicle I began to hear a ticking noise in the engine (lifter tick) and the check engine light came on. The vehicle began to lose power and started shaking. I stopped the vehicle and turned it off and restarted it and began to drive as I was not far from home. I found that the vehicle did not have full power and was not firing on all cylinders. After getting the vehicle home a diagnostic code showed cylinder 2 was not firing. The vehicle was towed to the dealership who confirmed there was a bad lifter and roller that dug into the camshaft. The sudden loss of power and shaking of the vehicle while driving is the safety concern. It seems that this is a common problem with these engines that GM is aware of and has failed to address.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle remained stuck in 3rd and in 4th gears upon depressing the accelerator pedal. Additionally, the vehicle contact stated that the vehicle experienced a hard shift while driving. The contact stopped, parked, and turned off the vehicle for 10 minutes; however, the failure recurred while driving. The vehicle was taken to a dealer, where the failure could not be replicated. The contact was informed that the vehicle was operating as designed. The manufacturer was notified of the failure. The failure mileage was 3,900.

Driving my truck and I suddenly got a warning on my dashboard that said, "Low Oil Pressure. Turn Engine Off." I pulled over immediately, shut off the the engine and called for a tow. Dealership called to let me know the engine was seized and would cost $22,270 to repair. Looking online I found that Chevy had released a Customer Service Program (CSP) detailing that the oil coolant lines in 2019 Silverado 1500 could have a weak / defective crimp holding the oil coolant line onto the connector and could separate causing catastrophic oil loss. It is also stated in the CSP that cold weather makes the issue more likely. I have tried getting GM to cover the repair since they knew about the issue and never contacted me to make the fix. GM is maintaining that they did nothing wrong and that my VIN is not listed as one of the vehicles in need of repair. This, despite the acknowledgement of the CSP and that the CSP "is for the dealerships." Which I pointed out the correction listed was for me to have the oil lines replaced and that never happened. I also pointed out as they said this wouldn't have been listined on my VIN because it was for dealerships and yet no one: not GM, not the dealership I bought the truck from, nor the dealership that regularly serviced my truck mentioned the oil line issue to me.
