2021 Chevrolet Silverado Complaint Log

rear third brake light is leaking water into the cab and causing water stains on the headliner. I am worried about it eventually causing an electrical short or more water damage. I don't have a rear window that slides open and the rear glass has never been replaced nor has the third brake light all original from factory.

The 8-speed automatic transmission (8L90) has been failing. It has put me in my passengers safety at risk because my truck can lurch forward without warning due to delayed downshifting and RPM surge. Yes, the dealership has confirmed this issue multiple times. The component has been inspected by the dealership multiple times. Yes, check engine light came on and yes there was symptoms before the failure such as lurching jerking, surging harsh and erratic shifting. They first appeared at 55,000, MI. It continues to happen to this day. I have an appointment scheduled for today at 9:20 a.m. for the dealership to look at it again but this is a legitimate concern.

While driving on the highway the engine shimmered and shut down. I lost all steering and braking power. After 20 minutes I was able to restart and drive off the highway at a reduced speed. upon exiting the engine died again. The following day I took it to sunrise Chevy in Glendale Hights IL as this was just down the road from where it sat all night. Service rep called and said I need a new engine with only 81000 miles. It was major lifter failure he said. Job was done at a cost of 9417.89. With less than 1000 miles on the new GM engine I was coming home on [XXX] at night when I lost all power to steering and brakes, dashboard lit up. Made it to the shoulder and towed back to the dealer. Once again major engine failure. At least this one was under warranty. but still very dangerous on the highway. Needs to be a recall please.

The vehicle was taken to a local dealer, and it was informed that it was normal operation for vehicles with the 6.2L engine. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case for the contact and referred the contact to the NHTSA Hotline to report the failure.

On three separate instances (two after paying $3,000 to "fix" it) my 2021 Trailboss is flashing warnings of: Park Assist Off, Steering Assist is Reduced Drive with Care, Service 4WD, Service Trailor Brake System...all while driving down the rode and losing all gauges/flatlining and no fuel warning engaging (had a 1/2 tank). The Chevrolet Dealer claims it's not producing a code (Thankfully I recorded the evidence)...Truck has just over 40k miles and has been driven with care. **Pictures are all while driving down the road** Serious electrical and SAFETY ISSUE and it needs to be RECALLED and addressed!

Engine suddenly began to run rough and slowed substantially while driving. If this occurred at highway speed, it could have presented a safety risk. Multiple check engine lights and error messages appeared at the time of the event - "service emissions system" and "65mph max speed" Dealer inspected vehicle and found a shorted wiring harness and fuel injector. The faulty parts were replaced

Started having a rubbing sound in rear end of vehicle. Took it to dealer. Brake calipers are a issue on this model and dealer says, “ found updated rear brake calipers with deflectors to help with dirt in rear calipers/not covered under warranty customer pay expense”, they are replacing rotors under warranty that got worn out. They want me to pay $2400 to purchase and have the “updated brake calipers” installed. If brake calipers are updated then that means there is a known issue with them. Spoke with the manufacturer and they said too bad.

Tailgate opens on its own or doesn’t want to open with push button

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated while driving 70 MPH, the vehicle started to pull to the left and the contact became aware that front driver’s side wheel had separated from the vehicle. There was no warning light illuminated. The contact was able to pull over to the side of the road safely. The vehicle was towed to the dealer. A police report was filed.

Vehicle began to shudder on the highway, managed to pull off at next exit and drive to nearest gas station approximately 3 miles away from the highway. Vehicle was towed to neared GM dealership. Dealership has determined that the fault is caused by a failed or multiple failed Camshaft Lifters inside the engine. This has been reported to be a common issue with the GM 5.3L Engine with no active recalls. The vehicle shudder began on a highway during construction where the highway was restricted to one lane. There was an accident with bumper to bumper traffic where an ambulance required way. The vehicle was not in stable condition and could have caused safety risks to other drivers on the high way as well as my passengers and myself. There were no symptoms prior to the vehicle shudder, the Check Engine Light did not come on until about 3 miles of driving closer to the gas station. The Service is being warranted by GM. There are active GM tickets open. Vehicle is being serviced by Stickland Cadillac Buick GMC Chevy in Brantford Ontario Canada

Engine lifters failed at 36000 miles, causing the vehicle to misfire. Engine lifters failed a second time at 42000 miles after being repaired, again causing the engine to misfire.

The truck lunges sometimes, and will jerk shifting, also at variable speeds the truck will feel like it is "riding over rumble strips at a low speed" at variable speeds 30 MPH to 70 MPH. It makes for an unsafe feeling having the vehicle lunge unexpectedly, and the shuddering on the highway causes alarming panic, and reaction, and a feeling of delayed response from the accelerator. Yes, everyone says it is a known GM issue, but nothing will be done, unless I contact a lawyer. No No warnings, or lamps of any kind.

It’s been going on for some time and have taken it to the dealership for request but with no help. The transmission keeps shuttering bucking between gears this is sometimes violent but seems to be becoming more frequent. This is mostly between speeds of 50-60mph

While pulling out into traffic the vehicle will momentarily lose all electrical power and the engine shuts off causing loss of brakes and steering.

While parked I turned on the truck and got service sec warning and power steering failure. Brakes barely worked and wheel was locked. After restarting the car three times it went away and truck became driveable. Took it to a dealership and they said there’s nothing they could do as a code didn’t pop. Seems unacceptable as my family is consistently in the car and if it happens while driving could be extremely dangerous

I bought this vehicle brand new off the lot in 2021. Truck hasn’t had any problems until this year. Every few weeks it will randomly just not want to start, I’ll usually check the battery and the battery will be completely drained. I can’t figure out what is causing the battery to drain like this, but something needs to be done as I have literally been stranded places due to my truck just deciding not to start randomly. Today i’m having this exact problem, my trucked was parked overnight in my garage and I went to go to work this morning and once again the truck won’t start and battery is drained. All my doors are shut and no interior lights are left on.

On 6.22.23 at Lake Powell AZ this truck transmission locked up twice and nearly threw the wife and I through the windshield, very traumatic!! Happened towing a boat entering highway, had to pull to a narrow shoulder. Jarred our bodies, seatbelt into shoulder/chest. The engine light came on, had truck towed to Flagstaff Chevrolet. Had it 3 weeks. Drove home to Huntington Beach, CA without issue. Drove fine until 10.21.23 when engine light came on. Took truck to Delillo Chevrolet on 10.30.23 where purchased, they diagnosed, said Flagstaff Chevy did not program trans. computer correctly, programmed and said it was good to go. Picked up truck on 10.30.23, drove about 50 miles 11.2.23 to work and back, that night went to drive and the engine light was back on. I turned off an hour later. I drove it the next day no engine light, leaving physical therapy for my recent shoulder replacement, going 40 mph when it did the same thing it did in June! It jolted me two times nearly hitting my head on the steering wheel. The transmission shifted to 1st gear, certainly red-lining the engine. I drove the truck slowly to Delillo, just a few miles away. I told the service manager I can never drive this truck again, it is unsafe, traumatizing waiting for this to happen again. I would never put my family in this truck again. It has caused me physical and emotional trauma. The vehicle is unsafe, the jolts caused my new shoulder to hurt. It is devastating to think what would happen if I was at freeway speeds. Others need to know about this issue as well. Thank you so much for your time and what you do to ensure the safety of vehicles on the road.

Electric power steering loss. Message stated to service power steering and ecs. Could not control vehicle.. After powered off for 20 minutes it went away and then was towed to dealer who found nothing wrong. Extremely unsafe!

I was cruising down the freeway at around 60 miles an hour when the vehicle started stuttering and shaking and I could not accelerate. The truck couldn’t get out of its own way and was a danger to my family. I took the truck to the dealer where they told me I had a lifter failure. They replaced the bank of lifters on the one side of the engine where the failure occurred and sent me on the way. I’m hearing the lifters is a common issue from multiple dealers. I’m not sure I feel confident in my vehicle any longer. I would prefer the dealer or manufacture to buy it back at this point.

Total catastrophic engine failure. Occurred at roughly 80,000 miles. Engine bearing shattered causing total engine loss. Needed to be replaced. Occurred in May 2023.

The first incident that happened to the vehicle was two weeks after the purchase the engine light came on and the pressure dropped and the truck was riding rough and driving slow on a main street 35 miles from my house. The 2nd incident had around three weeks after being in the dealership for a few days with the same code and symptoms as the first incident. The third incident happened three weeks ago while on the highway the engine light came on engine pressure dropped and it drove rough and slow during consistent traffic and I had to pull over. I contacted the dealership and made an appointment. My vehicle wasn`t driven for two days until it was taken to the dealership. The engine light has come on many times through my ownership of the vehicle. I don`t feel safe driving this vehicle

The tailgate electronic release will randomly open allowing the tailgate to open while driving or parked. This causes your secured load in the bed of truck to now become unsecured. This also forces the driver to make an emergency stop to secure the tailgate. The switch can release the tailgate multiple times causing the operator to spend an excessive amount of time getting the tailgate closed and secured.

The tailgate will randomly open while driving allowing contents to fall from the bed of the truck

My safety system service warning comes on for about 30 seconds and then goes back off. This has happened about 4 times now. The transmission causes my truck to shake randomly. My pulley is going out and the local dealer said they wouldn't replace is under warranty(even though my warranty was still is effect) because they said it looked like someone sprayed tire cleaner under the hood(I bought it from the same dealership that I took it to for this service.) The brake seem to shake already when coming to a stop. They seem as if they are wearing prematurely.

I was driving one day and my truck started to misfire. I figured since it had 95,000 miles it was time for a tune-up. So I took my truck to the Chevrolet dealership and they originally quoted me $2,200. The rep and mechanic said they have seen many trucks just like mine having the same issue. They said it starts with something called a “rocker arm” breaking and then that leads to more severe issues. After a month of my truck sitting they came to me and said it will cost $8,100 to fix it. Basically they replaced the engine. My complaint is I’ve had many vehicles and none of them needed an engine replaced after only 95,000 miles. I later found out that the engine that’s in my truck is a 4 cylinder which is a very low power/small engine which is expected to handle the weight of the truck along with towing. I just believe it was a poor design and that engine is ill equipped for a truck and the dealership/manufacturer should bear responsibility for that.

Had the check engine and recieved code p0303 cylinder 3 misfires i replaced fuel injectors on that side spark plugs ,wires ,spark plug solenoid,and still had the check engine p030 and would not run right my mechanic had to take the head off and replace all the valves of the motor costing me more than $5,000 i am so embarrass cause i was so honored to buy this silverado,but at 60,000miles this should nit happen why am i throwing alot of money to this truck gm you guys are letting me down i always by gm but at this point i dont know can you make this right,and no i dont want a 10 percent discount in a new one that a slap on my face .

I have major rust on the frame I just purchased the truck. Is their a recall on 2021 Silverado frames1500 custom.

I had a head on crash on 2/14/23. The other driver was moving in excess of 50mph. The hit was center of the front bumper pushing the bumper and radiator in to the engine compartment. No air bag deployment. However the Onstar system activated immediately.

Loud growling. Breaks safety concern due to fail.

ESC failed. The 2021 Chevy Silverado (39495 mi) began to shutter and a slight bouncing of the rear end. The ESC light came on the service ESC warning on the dashboard then the check engine light began to blink at the same time the parking brake light came on. The dash warning switched to have parking brake serviced. The truck as best as I could tell applied the parking brake several times for no reason while at highway speeds and traffic on all sides. All warnings stopped when Auto engine shut down at exit ramp light. Previously brought into dealership for “Service ECS” and “Service Power Steering Drive With Care”. I was told “ unable to replicate “ (23194 mi). Vehicle was returned to me. They did confirm the dash warning was stored in the computer. I do not believe any warning (blinkers) or brake lights came on to warn vehicles behind me of the rear brakes being applied by the ESC.

There is a current recall on this type of vehicle because the spare tire is not the correct size for the vehicle. This is recall #N212346510. Unfortunately, my specific vehicle is not included in that recall for some unknown reason. I experienced a flat tire, road service came and replaced with the spare which is too small for the vehicle, and I was only able to travel to a tire dealership in order to have the original tire repaired and placed back on the vehicle. I still have the wrong size spare even though there is an open recall for this problem. The dealership will not replace the spare without manufacturer recall one my specific vehicle VIN and/or direction to complete the exchange from the manufacturer. Evidently, only a certain percentage of the effected vehicles were recalled. That hardly seems safe. This problem can lead to issues with the brake system if a car uses the wrong size spare. How do I get my specific vehicle added to this recall in order to have the needed service? Please advise. Thank you.

This is a potential problem for a serious injury to a child , stroller, pet - or damage to front of truck and vehicle in front of truck. The hood of the truck is very high. And sitting in the drivers seat you are "driving blind. " It is impossible to see an object directly in front at bumper level. The only way to judge the distance to an object, or small person, is to get out of the truck and look. I had minor damage to the front of the truck by hitting my garage. But more seriously if there were a child or stroller- you literally cannot see it. This could be easily fixed with a forward looking camera - and the truck comes with a rear one- but Chevynfirs not offer any front camera/ park assist on any of its Silverado 1500's.!The manual says park assist is an option- but Chevy currently does not offer that option. This is dangerous..

The 2021 LT Trail Boss with the 5.3L engine started a really rough idle, engine knocking, random misfiring, had Service Emergency Brake, Service ESC messages on the display, check engine light and several other dash warning lights. The dealer diagnosed the truck with lifter fail apart (failure), intake valve push rod bent, and PCM failure. Odometer reading 19,368 miles.

So I have been having issues with my truck losing oil. My dealership told me that Walmart made an issue with the oil filter causing it to leak oil out. After the dealership corrected the issue. I was on my way to the store this morning it was damp so I was having a lot of traction issues. Got to the gas station checked tires, no issue with them. Temperature is above freezing. Just thought maybe it’s in my head. Well I get about 2 miles from my house and low oil light comes on again. So this is an issue. It has happened 2 times to me. Had I not been cautious I could have slipped off the road or had a collision because the oil mixing with the water on the roadways. I will be reaching out to my dealership tomorrow to try and get them to correct this issue again. Seems there is a service bulletin on how to tighten the oil filter. Because of oil leaks.

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving off an off-ramp at approximately 40-60 MPH and depressing the brake pedal, the vehicle suddenly lost power and turned off. The contact restarted the vehicle to continue driving. The failure had occurred twice. The contact stated that while driving at various speeds and depressing the brake pedal, the brakes grabbed, causing the vehicle to lunge forward, decelerate, and then lunge forward again, before coming to a complete stop.

On 12/26/22 my wife noticed a noise coming from the engine of the pick up truck. On 12/27/22 I started the truck and noticed a noise coming from the engine. I lifted the hood to try and locate where the noise was coming from but I could not see anything. There were no lights on the dash. I drove to work and parked it. 8 hours later I started the truck back up and the noise was still there. I began driving home and the truck made a spurted noise causing me to jerk the wheel nearly driving off the roadway. The truck is still making the noise. I contacted the Chevy dealer and they explained they would take a look into the issue. I’ve done some research and noticed that a bunch of 2020-2022 Silverado’s have been having lifter issues. I’ve also seen that the dealers are only replacing one side of the lifter banks and the others are failing 500-2000 miles after the repairs. I’ve also seen that people’s trucks have failed on highways and streets causing accidents and or traffic hazards. This is something Chevy needs to look into and fix to prevent any serious injury or death created by these issues. I don’t have photos but I do have a video of the noise that I could email if need be since I can not attach the video to this form.

Anytime the weather gets colder than 32degrees Fahrenheit the DEF system freezes, which even if the tank is full makes the truck go into limp mode until it thaws out. The engine light pops on and off with no codes associated with it. Now the breaks and break lines are freezing when it gets below freezing. These are just a few of the reoccurring problems we’ve experienced since buying the truck less than a year ago.
