2021 Chevrolet Tahoe Complaint Log

third row sealbelt buckle retention been a problem since 08/2022 and no one has given me a call. IF I get in a car accident it can increase the risk of injury for the people in the 3rd row. i have no accidents but I'm trying to prevent it from having one.

FUEL PUMP MODULE FAILURE. ENGINE DIED AT A STOP LIGHT AND WOULD NOT RESTART. UNABLE TO SHIFT INTO NEUTRAL TO TOW OR REMOVE FROM HAZARDOUS ROADWAY. PART ON NATIONAL BACKORDER.

While driving on the highway there was a loud explosion like sound. The sunroof on the SUV completely shattered. There was no car in front of me and no overpasses. Sunroof shattered and glass came in the car. I was driving the speed limit which is 70MPH and there was no forewarning. GM is scheduled to look at the vehicle, I am waiting on their return call.

without warning the engine shut off and lost power while driving. the engine light came on. i was able to pull over to the side of the road. I'm glad I wasn't at interstate speeds, that would of been bad. It was like i ran out of fuel. it was the fuel pump power control module according to the dealership.

GM decided to use Brembo brand brake pads and rotors on the front of the newly redesigned 2021 PPV Tahoe. I have 16 of these vehicles in my fleet at the Sheriff’s Office and everyone one of them squeals really loudly when the brakes are applied. I now have one Tahoe out of service due to the fact it needs pads and rotors on all four corners. The main concern is there are no rotors available anywhere for these units.

Car stalled while driving on the highway, no warning, car became unresponsive and we almost had an accident attempting to move car off the highway. This was an extreme safety risk. Car was dead, unable to start. Towed car to dealership, told it was the fuel control module that was not working. Found out this was a known issue for 2021 Tahoe, no recall was issued for my vehicle, no one notified or warned me of the risk.

Received an Over-the-Air update that rendered my vehicle unless. My vehicle would no longer start, or power on, or power on in accessory mode. It was stuck in Park, the electronic Parking Brake could not be disengaged, the door locks could not be operated and left unlocked, no lights, no warning lights, the emergency lights did not function, no horn, and most everything else. The only things still working were the radio, the driver's side powered seat would move, and the light came on for the Parking Brake. The battery was fully charged. I also started receiving messages through my Chevrolet APP that the vehicle had no air in the tires, no oil in the engine, and many other items that needed servicing. I am not sure what exact components or computers have failed yet. GM could not find any dealer to render aid and come to my location to reprogram the vehicle. It had to be towed to a dealer. With the electronic Parking Brake engaged, GM had a hard time trying to find a tow truck that wouldn't just drag the vehicle down my driveway and onto a flatbed.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while operating the vehicle, the warning message "service restraint system" was displayed and the air bag warning light was illuminated. The vehicle was taken to the local dealer who diagnosed that the electrical wiring under the front driver’s side seat was damaged from moving the seat back and forth. In addition, the contact also indicated that while operating the vehicle the message "Power Steering" was displayed and the steering wheel became difficult to turn in either direction. The cause of the failures was not yet determined. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was 140,000.

On November 9th, 2022 my wife was returning from the store when our Tahoe lost power and the engine shut off. She was able to pull off the highway onto a side street prior to the engine shutting off. I met her at that spot to see what was going on with the vehicle. The car was parked on a slight hill and after checking the oil and other fluids I could not see an issue with the car and the car would still not start. I was able to tow the car to a flat spot and checked the fluids again. After about 45 minutes the car did restart with the check engine light on. We were able to get the vehicle to an auto shop about a 1/4 mile down the road where they were able to hook up their reader and see what the check engine light was for. A code of P129F came up which is the fuel pump module, pictures attached of screen. We then were able to get the car home and it was towed to a Chevy dealership the following day. There techs were able to find a recall number of 21V739000 which was issued on 9-23-2021 showed that this happened in certain 2021 Tahoe's. While our vin number did not fit into the vin numbers on the recall number I still feel this was the issue. I feel this could be a bigger safety issue with other vehicles on the road that did not fit into that recall could still have the issue. While we were lucky and know one was injured the next people may not be so lucky. Also since our Tahoe was not in the range of VIN numbers on the recall we are being forced to pay out of pocket 521.81. Which I will be fighting Chevrolet to pay us back.

Power steering has failed completely, can not turn at all unless its slightly.

2022 Tahoe was inspected for the announced recall. The manufacturer Chevy has no timeline for when the 3rd row seat belts will be repaired but only said we CANNOT use any of the 3rd row seats till fully repaired. I called chevy and ask them what’s the suggestion what’s if the passenger is 5 or more. Will the give rental fee or a loaner vehicle. They said no. This is totally unacceptable. GM is offering nothing to customers that purchased $74000+ vehicles from them for the very reason that they have big 3rd rows. How are families of 5 or more supposed to function in the meantime? NHTSA should exert all available pressure on GM to prioritize on-road vehicles and do it now.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the vehicle stalled without warning. The contact stated that the transmission independently moved into park (P) and the gear shifter would not move after several attempts. The vehicle was towed to a dealer who informed the contact that they could not repair the vehicle because they did not have the adequate tool to unlock the transmission. Upon receiving the tool days later, the dealer diagnosed that water had leaked into the fuel tank, which led to the failure. The manufacturer was notified of the failure and advised the contact that they would follow up. The contact was still awaiting a call back from the manufacturer. The vehicle was not repaired. The failure mileage was approximately 27,000.

Our Tahoe was inspected for the announced recall and failed the test. The dealer/manufacturer has absolutely no timeline for when the 3rd row seat belts will be repaired and said we cannot use any of the 3rd row seats until then. The dealer even said it could be a year before parts are available. This is totally unacceptable. Has GM rerouted new seat belt assemblies from their manufacturing of new vehicles to prioritize repairs of vehicles already on the road vs. keeping their sales pipeline full? I doubt it. Are dealers prioritizing vehicles on the road over those on their lots that are waiting to be sold. I doubt it. These are the very questions NHTSA should be asking of GM. GM is offering nothing to customers that purchased $70,000+ vehicles from them for the very reason that they have big 3rd rows. How are families of 5 or more supposed to function in the meantime? NHTSA should exert all available pressure on GM to prioritize on-road vehicles and do it now.

The contact owns a 2021 Chevrolet Tahoe. The contact received a notification for NHTSA Campaign Number: 22V617000 (Seat Belts) however, the part to do the recall repair was unavailable. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure. VIN tool confirms parts not available.

Recently, while idling in parking space the vehicle stalled and engine and fuel lights came on. The vehicle was towed to the nearest dealer, and the diagnosis was a failure of the fuel pump control module. The vehicle has less than 10,500 miles. The dealer stated that over the last four days, two other vehicles were brought in for the same issue.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving approximately 65 MPH with the adaptive cruise control activated, the vehicle stalled and lost motive power. The contact indicated that after the adaptive cruise control reduced the speed due to a nearby vehicle instead of resuming the intended speed, the vehicle lost motive power in the middle of the busy highway and would not restart. The tow truck was called to the scene and discovered that the transmission could not be shifted into neutral(N). The vehicle had to be dragged onto the flatbed of the tow truck. The vehicle was towed to the local dealer. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 14,608.

Traction control light came on and the vehicle felt like it was going to die/low idle. I took to dealership on 9/13/22 (5months after getting vehicle) and the codes P03000 00 which is an engine misfire, P050D 00 which is cold start rough idle and it was noted by service tech that engine making a clunk and ticking noise. There was a misfire on cylinder 6. They removed the valve cover and the intake valve rocker arm was not moving at all and when the rocker arm was removed they noticed the push rod was also bent. They verified the DFM lifter was collapsed.

Fuel module failure while driving, engine stalled and would not restart.., while at highway speed. Very dangerous situation!!!!! Tahoe was towed to dealership kept for. 1day. Chevy dealer replaced fuel module. We have owned 6 different Tahoes starting with the year 2015 to 2024. The fuel module failed on the 2021, 2022 and now the 2023!!!!!!! Makes us question if we should purchase a new Tahoe every other year? Seriously considering other car brands such as Ford, BMW or other more reliable brands!!!!

First fuel system failure occurred at ~3500 miles. Pulled out of driveway, shifted into drive and vehicle stalled and would not restart. Fuel pump replaced first then fuel module replaced resolving issue. Now at 12,100, vehicle again shut down at a major intersection and would not start. Vehicle has been towed to dealership. The vehicle failure mechanism locks the car in park and leaves all electronics powered on. Fortunately I was able to get the front wheels strait during one sputtering start attempt so it could be DRAGGED straight onto the tow truck. Able to power off radio and ac buT no other electronics would shutdown, dash display, resulting in total battery drain. Can only lock drivers door with key so vehicle is outside dealer service center on a weekend unlocked. This the second failure of the same component. This abrupt failure creates a completely unsafe situation leaving you stranded unable to move. This vehicle is an expensive failure and based on a second recurrence, the related electronic component issue has not been resolved. First occurrence Chevrolet provided a free year of OnStar due to me not feeling safe with this vehicle. Now just after this expired, the same failure has occurred. Buy this vehicle back from me Chevrolet at my purchase price. First occurrence took 3 hrs for a tow truck to pick up the car which was fortunately in middle of my street. This current failure was 2.5 hrs stuck at a stop sign in the middle of a major intersection. Thank God I was not on the interstate.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while reversing out of the driveway, the vehicle suddenly lost acceleration and the message to restart the vehicle was displayed on the instrument panel. While attempting to restart the vehicle, the vehicle failed to restart and another message that the conditions were not met to restart the vehicle was displayed. The contact contacted OnStar to assist with starting the vehicle. The vehicle was started; however, the engine failed to remain running. The vehicle was towed to the dealer who informed the contact that the VIN was included in NHTSA Campaign Number: 21V739000 (Fuel System, Gasoline) and completed the recall repair. The contact stated that approximately two years later after the recall repair was performed, the failure reoccurred while the vehicle was idling. The message to restart the vehicle was displayed on the instrument panel; however, while attempting to start the vehicle, the started sputtering. The vehicle was towed to the same dealer and the contact was informed that the vehicle needed to be repaired under the recall again. The dealer informed the contact that the remedy was no longer covered under the recall, but the repair would be covered under warranty. The dealer informed the contact that the part was on back order and the vehicle would be repaired once parts became available. The vehicle had not been repaired. The manufacturer was made aware of the failure and opened a case. The failure mileage was 8,345.

My car’s service safety restraint system alert is on for the second time. I took it to Hanner Chevrolet in Baird, TX the first time and they told me it was fixed. It stayed off for a few months until the alert lit up again. My car is available for inspection. According to the dealership, while that light is on, they cannot guarantee that my airbags will deploy in the event of a crash. The dealership has confirmed that there is a problem and has seen the same issue with many other 2021 Tahoes. My vehicle has only been inspected by the dealership so far. The warning lamp is currently on. Luckily I have not had an accident in my vehicle, but I feel unsafe driving it at this time until the issue is resolved. After speaking with the dealership and researching online, it appears that this is a common issue with the 2021 Chevrolet Tahoe and creates a significant safety threat. I believe a recall might be required.

On 7/13/2022, I was driving down the highway and my Tahoe without any warning began to decelerate. I put on hazards and merged over in rush hour morning traffic off to side of the highway. I looked to put it in park and it had switched itself into Neutral. I immediately shut the car off and tried 3-4 times to start it. Had to wait 5 minutes then got it started and back on road I went. The previous evening, the My Chevrolet App showed I had a flat driver side rear tire but in fact, I didn't.

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

Gps/onstar module not working, I read a lot of people are complaining same thing. I had it for a year, warranty done but I never used it. Sad you spend $70k on a truck and onstar goes bad and you never used it and they want more money to replace it. Now engine light is on.

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.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while his wife was driving at undisclosed speeds, there was an abnormal ticking sound coming from the vehicle. The check engine warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed, and determined that the cylinder #1 left side lifters and push rod had collapsed. The lifters and push rod assembly were replaced. The contact stated that on a separate occasion, while driving at undisclosed speeds, there was an abnormal ticking sound coming from the vehicle, and the check engine warning light illuminated. The vehicle was taken to the local dealer, where it was diagnosed, and determined that cylinder #4 lifters had detached, and the push rod was bent. The vehicle was repaired. The contact stated that the engine was consuming an excessive amount of engine oil. The contact related the failure to TSB: 15-06-01-002A. The dealer and manufacturer were not made aware of the failure. The failure mileage was approximately 12,400.

INTERMITNLY STALLS WHEN DRIVING at dealer now being addressed no warning light before issue happened three times now starting in April

Brakes squeal a lot. Had to pay close to 2k dollars for repairs because dealer refused to warranty

Took the vehicle in for Airbag System recall in 2022. They said they fixed it and that there was a broken wire. The very next day the warning light came on again like before. I contacted the dealership and they said bring it in. I could not get it in again as I was very busy. I asked them to make a note in my file of the immediate call/report of still a problem. I took the vehicle in this month (October 2024) for issue of no starting (fuel pump failure, another recall they are denying). They stated that the Drivers Side Airbag module was shorted or bad and my cost would be approximately $1,250. They stated it was not covered under any recall. I contacted Chevy corporate that offered to cover 30% only of this. I believe this should be covered in whole due to the failure to repair the first time and that is is a known safety issue. The vehicle has only 10,800 miles.

The contact owns a 2021 Chevrolet Tahoe. The contact stated while driving 65 MPH, the vehicle experienced phantom braking and stopped suddenly. The adaptive cruise control warning light was illuminated. The contact stated that after several minutes the vehicle started operating normally. The vehicle was taken to the dealer however, no cause for the failure was found. The manufacturer was not contacted. The failure mileage was 10,000.

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.

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.

My Tahoe 2021 RST has been leaking what smells like diesel. This goes all the way back only months after I bought it new. This came and went sometimes once a week sometimes once a month. And for the next few years many months I could smell it but no leaks but in the last 10 days the diesel leak has been massive. It leaks from under the engine and if the hood is opened the diesel leak is all over the engine. The smell has been noxious sunce the beginning. Over the years the smell was there off and on. Comes and goes. But the last few months it has been everyday. Apparently the shop had fixed and replaced some parts several weeks ago but the smell of diesel never went away. Now it is in the dealer shop again. Because the fuel leak is too massive and the smell is ever worst.

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.

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.

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.

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.

The contact owns a 2021 Chevrolet Tahoe. The contact stated while driving 35 MPH, there was a loud knocking sound coming from the vehicle and the vehicle was shaking abnormally. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer for diagnostic testing and the contact was made aware of a cylinder #3 misfire which caused the lifters to fail. The contact stated that the lifters on the driver’s side and the gaskets, bolts, and rods were replaced; however, the failure recurred. The manufacture was not contacted or notified of the failure. The failure mileage was 16,786.

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.

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.

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.

Exhaust fumes in cabin from back presure valve welds

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.
