2021 CHEVROLET TAHOE Complaints

I was driving to work today and I heard what sounded like an explosion, so I stopped and pulled to the side of the road and checked everything and I seen that the sunroof glass was broken, I have only ever used the sunroof twice and that was to see if it was working. My safety and others on the road were at risk because if I would have had the sunroof sliding shade open the glass would have fell on my head or in my face. Also anyone driving behind me I'm sure the glass flew on their vehicle and could caused an accident. I got to work and called the local Chevrolet dealership in town and they said there were no recalls for this problem, but yet I looked it up under GMC forums and there has been other people saying it happened to them, especially the same year and make and model. My vehicle has not been inspected by the manufacturer, police or insurance yet, I reached out to the Chevrolet dealership and they said there was nothing they could do to help because there were no recalls on my vehicle, so I asked the girl in the service department who was higher then her and could help me because I did nothing wrong and did not feel that I should have to pay to fix this problem. She then gave me customer care contact information and I am waiting for a response. There were no warnings or symptoms or any messages on the dash, my sunroof glass just exploded without any warnings.

When turning left in cross traffic, the truck stalled. It would crank and try to run, but not start as it wasn't getting any gas. The gas tank was full at the time. The failure was very similar to when I was stranded with the fuel issue in 2021 a couple of months before the recall for the fuel pump failure was issued (NTSA # 21V739000). Fortunately, it did start momentarily so that I could get out of oncoming traffic so that I wasn't t-boned. I was able to get it home, but it failed multiple times in the 8 mile trip back to the house. We will not drive this vehicle as it is unsafe to drive and now we are left to tow the vehicle to the closest dealership which is 50+ miles away. It seems this part only works a few years and then fails.

I was parked with engine on idling and the engine shut off. Tried to restart and it started shaking very rough idle, I turned off and tried to restart it would not start, I tried again and it started shaking again and shut off but the displays stayed on in the car. I called the Chevy dealer and had it towed to them. They ran diagnostics and confirmed it was an internal short inside fuel pump driver control module. They replaced and tested functional now. This is the second time they have replaced this part. The first time was last year driving when the engine decelerated and shut off. This is a safety issue and could be hazardous. My concern is this will happen again and I could be put in a very dangerous situation. I saw a bulletin issued for my vehicle with the same type of issue but my vehicle was not recalled to address Product Safety Recall N212332040 Stall While Driving Copyright 2021 General Motors. All Rights Reserved. Page 1 of 4 Release Date: October 2021 I am not sure if this is the same part or another issue.

Service engine light came on, took it to Chevrolet dealership (2 months outside warranty). They found p2459 for regeneration frequency, performed necessary dpf regeneration procedure and was successful in completing and regeneration event, applied smoke to exhaust system for testing purposes and found large exhaust leak at rear tail pipe connection necessary to install new graphite seal and clamp. Also, found coolant leak at rear of engine on passenger side, upon further inspection found egr cooler coolant hose's actively leaking. necessary to replace hose's at this time. They do not want to release the vehicle back to us for “safety” reasons, while a part has been back ordered for 6 weeks. Doing some research, it appears there has been a trend of issues with the exhaust tail pipe, which is excluded also from extended warranty. I’m surprised, given the frequency of this on a newer vehicle that it has not yet been recalled. The coolant hose is a different issue, but likewise surprised it is not recalled.

I have a 2021 Chevy Tahoe that has been to the dealer 3 times now for an airbag light (DTC B14DC). The dealer has yet to resolve this issue. I am being told it has to do with the harness in my drivers seat. The dealer performed a TSB for this issue which still hasn't fixed the problem. My wife and I travel back and forth from Michigan to Arizona and I am concerned that the system wont perform correctly if I am in an accident.

2 ISSUES - 1) vehicle repaired 5 times for "transmission" problem by replacing wiring harnesses. On 5th attempt, the GM factory part or the technician caused the Tahoe to catch fire. Worst part is that it happened 1 hour after test driving and parking the car at their dealership, thankfully, I would normally have driven it home and it would have destroyed my home too. GM investigated and was unable to determine cause. 2) each time the "transmission" error occurred the GM car went into what they call the "limp" mode. The car immediately loses speed control and drifts to about 35 mph until you have control of the accelerator. I was on an interstate going +70 mph to pass a semi and immediately after passing the car went into Limp Mode, the semi nearly rear ended me and then passed me blowing his horn and cursing me. GM could certainly correct this latter issue by creating a warning on the screen that gives the driver ample time to pull over and address the problem as they do when DEF fluid (this was a diesel) is low and will give warning to add DEF or reduce speed after so many additional miles are driven. The former issue needs to be addressed immediately too, I've noted 4 other drivers on social media that had similar fires. Both of these issues could have resulted in serious injury to me or my family.
