Representative owner complaints
453 reports, newest first.
Engine, Jun 13, 2022
The lifters failed at 18,000 miles stranded on the side of the road with 3 kids for hours. Only one side is apparently being replaced, leaving me just waiting for the other to go out. I was assured by the dealership that it would happen just would be a matter of when
Power train, Engine, Fuel/propulsion system, Apr 26, 2022
I encountered the same issue which most of the other complaints on here saw where the engine lost power (due to one cylinder misfiring) suddenly and it was due to a faulty lifter in the engine. Fortunately, I was able to limp the vehicle back to my house where it could be towed, but had it been worse it could've stalled in an intersection and I'd be unable to move the vehicle due to how the engine must be running in order to put it in Neutral. GM really needs to recall the engines that are affected by the lifter problem as this issue is showing up on several forums online along with this site. My engine date code falls within their TSB, however they only replaced one bank due to my mileage being over 8,000 miles. That means that I most likely get to look forward to more issues soon with the other bank of lifters as they're of the same faulty design.
Power train, Electrical system, Apr 11, 2022
The vehicle was manufactured with a push button transmission gear selector. If there is an electrical issue(ie. dead battery, electrical short, engine failure, etc) you cannot shift transmission gears. If I pull into my garage, notice a burning smell coming from engine area, possibly an electrical short, I cannot put vehicle in neutral to push out of garage in case it does erupt into a fire and not burn down my house. Recently my dead battery caused the tow company to lift the back end and pull it our of garage. General Motors did not install an override to put transmission in neutral in an emergency. The transmission will only shift if the engine is running. Imagine driving on a road or stopped at a traffic light and the engine stalls, will not restart, good Samaritans offer to push you off the road, but can't shift to neutral. Dealerships have a hydraulic lift they place under rear tires to move vehicle around service area. As a retired law enforcement officer, many times we had to move vehicles out of the way until wrecker serviced arrived. I feel this is definitely something that has to be addressed and corrected before major damage occurs or lives are endangered.
Air bags, Mar 23, 2022
My airbag light keeps flashing and an alert pops up “service safety restraint system.” Flashes on and off everyday the whole time I’m driving. I can’t even use my digital speedometer because it comes on so much.
Service brakes, Feb 18, 2022, crash
Brakes fail a low speed, less than 10 MPH. Happen three times. First time there was an accident. I have a dash cam. I had to place the Tahoe into park to get it to stop. Was at dealership for bent push rods for 15 day. I ask them to check the brakes. I guess there were to busy and never checked them (Nucar Chevrolet). https://www.youtube.com/watch?v=OFjiqRWFXuE
Power train, Feb 18, 2022
You cannot put the vehicle into Neutral unless the engine is running. This is a huge safety issue as my Tahoe broke down in the middle of a very busy intersection at night time, and it took 3 hours for a tow truck to show up. If I had been able to get the vehicle into Neutral, I could have pushed it out of the intersection into a safe location.
Power train, Feb 18, 2022
The lifters failed which caused my vehicle to stall in the middle of a very busy intersection. Chevrolet knows this lifters are an issue, but they need to treat it as a Safety Recall. When these fail, it happens while people are driving. It is a HUGE safety issue.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that upon the depression of the brake pedal, the vehicle would stall without warning. The contact had taken the vehicle to a dealer where they informed her of NHTSA Campaign Number: 21V739000 (Fuel System, Gasoline) however, the part to do the recall repair was not yet available. Since the initial failure, the vehicle had stalled twice without warning. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was approximately 20,000. Parts distribution disconnect.
Engine, Feb 7, 2022
Experienced a collapsed lifter on my 2021 Chevy Tahoe at 18,000 miles,also had a bent push rod, all whiling 40 mph. This is my second time having this issue. There is a problematic design with the active fuel management system. The frequency this is occurring is unacceptable. I also had the same issue on another GM truck at 120k miles which costs 6,000 dollars to repair.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that stated while the vehicle was parked and unoccupied caught fire without warning. The contact noticed there was smoke and flames emerging from the vehicle, and it burnt to the ground. There were no reported injuries. The contact's belongings purse and wallet were destroyed in the fire. The fire department extinguished the fire. A police report was not filed. The contact called the local dealer but the vehicle was not diagnosed or repaired. The manufacturer was contacted but, no further assistance was provided. The vehicle was towed to a salvage investigation lot by the insurance company. The approximate failure mileage 10,000.
Engine, Fuel/propulsion system, Jan 28, 2022
This model engine stalls/cuts out acceleration because of valve lifter problems. While Chevrolet has repaired many of these engines, they are waiting until the check engine light comes on (or flashes) to initiate the warranty repair. It is very possible to be miles from a dealer, requiring a tow, and the dealer not having the repair parts in stock.
Engine, Jan 11, 2022
GM has been building V8 engines with a known defect that is bending push rods and damaging lifters. These newer engines use a DFM system and that system is compounding this engine defect. GM has refused to replace all the lifters and is going forward with just fixing engines as they blow up which can happen at any time. The 5.3 and 6.2 engines are a ticking time bomb and can leave you without engine power at any given time when a lifter fails or a push rod gets bent. Hopefully the NHTSA will look into this issue and force GM into a recall.

The sunroof made a very loud popping noise and exploded while driving on the interstate on November 30th around 12:15pm in about 40-50 degree temperatures. There were no warnings or noises or any indications that something was wrong. The safety of myself and children were put at risk, as the glass came down into the car while driving on the interstate, and presumably the safety of other drivers if some of the glass flew off onto the interstate. A local body shop has taken photos, as have I, and we have filed a claim with our insurance company. Our local GM dealer did not want to cover the cost under warranty, claiming there was no way to prove exactly what happened. The vehicle has been looked at and temporarily fixed by a local body shop, but not thoroughly inspected. The body shop has ordered new glass and will inspect the vehicle next week.

I have has this vehicle for just over a year, and in the time i have accumulated 8,600 miles. Suddenly, yesterday after normal I stopped for a red light. The start/stop function came on (normally) and then all of a sudden the vehicle restarted it self, but, it started running rough, and misfiring. when i moved it backfired several time. I had to have the car flat bedded to the dealer, and apparently it has a known issue, with the lifters and the push rods. The dealer stated it will take a while to get the parts. h as 5 others in the shop for the same problem. My comment is, I am lucky this happened at a stop, I think this would be a major issue if this was to happened at 65 MPH ? You could end up in an accident while you deal with the issue.
Steering, Suspension, Wheels, Nov 8, 2021, crash
While driving on a residential street during daylight hours, on a clear day at approximately 20 miles per hour the right wheel on my car dislodged. This caused me to lose control of steering the vehicle and strike a parked car. There were people walking about on the sidewalk at the time and other cars traveling. When I exited the car I saw that the passenger side was completely on the ground and there were broken pieces and liquid coming from underneath the car. The axel was broken with a clean break. The car was then towed to the dealership where I was informed it could not stay. My insurance company then towed it to their repair shop where upon assessing the damage they could tell that this was not caused by a collision. General Motors along with our independent investigator examined the parts and vehicle. Leaving me without a vehicle for 4 months. Our Insurance investigator determined this was a defect in manufacturing and GM did not agree. General Motors will not communicate with us any further on this matter. Some of the repairs that were made was the left front and CV axel, also the left front aluminum steering knuckle was missing. This should be investigated for metallurgical discrepancies by an independent lab. While the car was being inspected there was a recall to the power steering that may apply to the vehicle. I would like for the NHTSA to investigate this issue. The car has been repaired and is in my possession and my insurance company has all of the reports, documents, and parts regarding the investigation. I also have pictures immediately following and a witness to the incident. Had a been traveling on a highway at a higher rate of speed this could have been fatal. Your assistance in this matter would be greatly appreciated.

On 10/21/2021 while driving about 65 mph on highway 80 in Sacramento my sunroof glass exploded. It was not struck by any object. The weather at the time was rain and about 60 degrees. Traffic was light and nothing near that could have caused this to happen. Fortunately the shade was closed preventing any glass to enter the interior. Its been in at the dealer Stevens Creek Chevrolet in San Jose since 10/21/2021 waiting for a replacement glass. This incident could have injured anyone in the vehicle if the shade had not been drawn. So far it appears it is being handled as a warranty issue.
Electrical system, Engine, Forward collision avoidance, Oct 18, 2021
Traction control and forward collision warning lights stared to go crazy in August 2021 (3800 miles), five months after buying my Tahoe. Sales rep indicated his new 2021 Silverado did the same and he was able to get it to reset by turning off and restating his engine. So I did the same and thought my issue may have resolved itself. Yesterday, the warning lights started to go haywire again (6700 miles) This time my vehicle felt as though it was going to stall and was making a clicking noise under the hood. The warning lights continue to flash regardless of how many times I turn on and off the engine. The engine also revs loudly.

I purchased a 2021 Chevy Tahoe from Autonation Chevrolet 11-3-2020. I have taken my Tahoe to the service department numerous times - as my truck has had a stubborn service safety restraint system warning error code that continues to come on and off. I have taken it to have all recalls serviced as per recall request. The service safety restraint system warning code has not been corrected after more than 5-6 visits if not more as not all visits have been logged properly. I have had this truck for less than 12 months and have experienced too many conflicting issues. I do NOT feel safe driving my Tahoe with the SRS light on. There's obviously a malfunction that you all have not been able to figure out. This is extremely dangerous!! What if I were to get involved in an accident or collision and my airbags do not deploy? I may have a problem with the airbags themselves, a loose wire, a faulty seat belt buckle, or a problem with the engine control unit which is causing the airbag warning to come on. There is obviously a major problem. I am putting my children and family at risk. I have not received an email or phone call from anyone at Autonation Chevrolet. The service safety restraint system warning code has come on and off 7x since I was last at the dealership (9/10/21) and I have pictures to support.

In late May, 2021, an "over-the-air" software update was forced onto our vehicle by GM. This update was initiated, and resulted in a failure of the over-the-air system. We brought our vehicle in to our dealer, who indicated that the "module" is bad and a part is required to fix it. This part is reportedly "on backorder" with no known ETA. This has resulted in various notifications (turn signal indicators, and unknown other notifications on the dash) as well as our center console (music, nav, etc.) to become unresponsive. Since the "module" failure, GM has issued two additional safety recalls. In the paper notices we received for the safety recalls, GM indicates that they had been "prompting owners through the vehicle's radio screen" for a month, via this over-the air system, of which, ours has not been functional since late May 2021. The last of which is a power steering recall, which may result if loss of power steering functionality. Due to our inability to know the recall existed, resulting from the faulty "over-the-air" system, my family took a trip through the mountains only to return home to this recall notice. GM has been unresponsive in repairing the system used to notify us safety hazards related to the vehicle that we have purchased, beyond noting that they are trying to "get the part as soon as possible". No one has been able to indicate what this "part" actually is, to date. The possibility of this module failure, and our non-functioning module, presents a serious safety hazard to drivers with this technology who are not made aware of recalls and other safety concerns which may result in crashes and serious injury or death.

The engine started knocking and running rough. My wife pulled the car over. She could tell from the sound it was not a minor issue. We had the 2021 Tahoe toed to Vaden Chevrolet in Beaufort, SC, where we purchased the vehicle. The dealer confirmed it was an engine problem. 8 lifters along with other associated parts need to be replace. This is a major engine repair. The vehicle is 8 months old and has approximately 10,000 miles on it. Doing internet search, the failure of engine lifters in Tahoes and Silverados appears to be a known problem. The service department manager told me that they have already done 10 of these this year. Failure of an engine while driving is a major safety issue. The vehicle is in for repair, now.

There is a serious cabin air pressure issue in this vehicle. When driving at any speed with the windows up, there is a booming inside the cabin, as if the passengers are inside of a subwoofer. My theory is that the headliner panel has too much flexibility in it due to the ceiling air vents. When driving, it is likely the headliner is bouncing up and down, creating the booming air pressure. Within 2 weeks of delivery of this new car and daily driving, my passengers and I developed serious ear issues which we attributed to the car. It got to the point where I would immediately have pain and ringing in my ears just driving a very short distance. None of my other cars including SUVs cause or have ever caused this issue. It is important to note that with all 4 windows rolled down, the problem does not happen. It's only when the windows are up. I have the LS trim without the sunroof.

After turning off a major highway (65 mph) onto a side road after driving for approximately eight hours, the transmission shifted into N...on its own. The engine continued to run but the vehicle would not move. We could not shift into P, R or D. When attempting to shift into P, R or D, an error message appeared on the dashboard that said "Conditions not right for shifting." We turned the vehicle off and then back on and the error cleared. The vehicle continued to drive "normally" for another two hours and the end of the journey. Had this happened in the middle of heavy traffic, a deadly accident could have occurred. Mileage on vehicle is 4,900. Date: 13 July 2021 at 1800 hours. Dealer has been notified but has taken no action to date. There were no warning signs or messages prior to the incident. I'm guessing it is a sensor or software problem related to the engine/transmission. There is a paragraph in the Owner's Manual that states: "Under certain conditions, propulsion will be disabled. Try restarting after the ignition has been off for two minutes." It offers no other explanation as to what "under certain conditions" means.
