2021 CHEVROLET TAHOE Complaints

I have a 2021 Tahoe that while circling a parking lot at my son's football practice. The Tahoe's emergency came on and the Tahoe abruptly stopped. A checked engine light came on. The Tahoe wouldn't release the emergency brakes. I was finally able to get it released. I took the vehicle to a transmission shop because I plugged OBD scan tool on it. It had two transmission codes. One generic and one for the vavle body. The transmission shop said they have had lots of Tahoes with the vavle body's going out. They told me about N242454441. I called Chevrolet and they advised me that wasn't for my Tahoe. I asked why and they said they don't know. If this is effecting the desiel only models then why is mine doing the same thing. Parts cant be ordered either. Please look into this matter.

At low speeds the steering wheel locks up and become very difficult to turn. This has been an issue for a few years and only happens randomly. Reviewing N212333901 it is the same symptoms but for some reason my VIN is not covered in the recall while is the same year as affected vehicles (2021 Tahoe Z71)

Driving car, suddenly when accelerating engine light started flashing, car was shaking and making knocking noise

This is an amendment to campaign 11684444 as there is some inaccurate info as it pertains to the diagnostic- 2021 Chevrolet Tahoe, Driving 25 MPH, in the neighborhood, my Tahoe kicked into neutral and abruptly stopped in the middle of the street. I immediately tried to restart it, however it would not start. After about 15 minutes, we tried again and it started enough to make it back to my in laws house, where it remains parked today. We did a diagnostic test and received the code for Fuel Pump Control Module failure. Contacted the Chevrolet dealership I bought my vehicle from and they indicated this is a common issue and the part is on back order. This is a very dangerous risk to safety and should be covered under a recall. I've seen where GMC issued a recall for the exact same issue, but only for Tahoes with 6.2L V8 engine; Mine is 5.3L. I am confused why that matters as it poses the same safety risk across the board. Very dangerous. Please consider this as a recall.

2021 to 2024 has had countless problems with the 6.2l engine. General Motors has put a stop of sale on vehicles with this engine. When I purchased the car the wrong oil was in the car which always burned off with 2 months after an oil change. They figured out the right oil but the damage has already been done.

Rapid deceleration at 55mph on highway, followed by console message "reduced acceleration" with check engine light. Fortunately rolled into dealer within a mile. After analysis, they stated the transmission valve body and electronic control component needs replacement over $3,000. after tax. No warning signs prior. NTSB recall N24254441 covers only diesel engines not gas with same problem in 10 speed transmission.

On August 23, 2025 while driving on a highway with my daughter in the backseat, my car gradually stalled while it was going through an intersection. It ended up stalling prior to a turn ramp onto another highway. This resulted in an unsafe condition and unsafe location as it happened without warning or any alerts prior to or during the drive. The Tahoe was towed to the dealership service repair shop (Hendrick Chevrolet in Cary, NC) and was found to have a fuel pump control module failure requiring replacement (replacement: FP-number 13554821, module 3.900). The dealership service department acknowledged this is a part failure on the manufacturer end; however, mentioned this is a safety bulletin, but not a recall for the part. Due to the Tahoe being outside of warranty timeframe, this ended being an out of pocket expense. The service staff told us there were four other Tahoe vehicles waiting for this part at the dealership, and we waited over a week to obtain the part as it had to come from the manufacturing line. Due to the timeframe for repair (>1 week), we had associated rental car payments that was not provided by or covered by the dealership/manufacturer.
