FUEL/PROPULSION SYSTEM
Was in stop and go traffic. Car suddenly said “conditions not correct for shift” and engine died. The car would not turn on and it could not be put into neutral therefore was stuck in the lane stopping all traffic on the NJ turnpike. It created a safety issue for that reason as there was no way to move the car to a safe place until a tow truck came and had to drag it onto the bed. I have since had it repaired at a local shop not Chevrolet dealer and was told it was fuel pump failure. There was no warning or any other symptoms in facet I had just had an oil change a week prior. Had there not been stop and go traffic and I was going the speed limit (60mph), there could have been a major accident and injuries.

FUEL/PROPULSION SYSTEM
The fuel pump control module failed while I was driving. My vehicle shut down in the middle of the road. I was unable to put my vehicle in neutral to move it off the road. A tow truck had to come in order to get it out of traffic. The next day we had it towed to the dealership who replaced the fuel pump control module. This is a safety issue because the car will shut down with no warning while driving. It’s very dangerous. The second safety issue is that the vehicle becomes immovable without a tow truck. There is no accessible shift override to manually put the vehicle in neutral.

ELECTRICAL SYSTEM
Info center with radio, vehicle info, on star keeps going black screen. When this happens I loose all control of info center and on star goes out where no location would be available if the vehicle was in an accident. This is safety concern because with no automatic notifications of accident no one would know if vehicle was in an accident. The vehicle has been to dealer 4 times for this problem since February of this year. Each time the dealer says it needs another update each time. GM is having this issue with many of the Vehicles like this Tahoe. On Star is also aware of the issue too. GM knows there's an issue but now they are saying I have to pay for an update because I am out of my extended warranty even though this has been an ongoing problem which started when I was in warranty. This has to be a programming issue that they need to fix. The vehicle has to be shut off for up to an hour for screen and controls to come back on which is safety issue because no way to change any settings for vehicle and safety backup because of no on star.

FUEL/PROPULSION SYSTEM
My 2021 Chevrolet Tahoe suddenly shaked and the engine shut off and on and nearly stalled on the road. I towed the car to the servicing dealer who has not been able to fix the issue. There is a national recall for the issue for the month of September 2021 Safety recall N212332040 for this issue but NHTSA has not added my car. NHTSA must include my car with the same issue and built in during the same month of the recall. The safety issue is the car will stop running and may block traffic or can be hit when it breaks down.

ENGINE, UNKNOWN OR OTHER
We just recently had the cam shaft and lifters replaced, as the vehicle began experiencing a knocking sound. The repair was supposedly completed, and they gave the truck back. We took the truck back in within a week, bc we continued to hear the sound. They sent it back saying they didn’t hear anything after test driving it. Over the weekend the car shut off after beginning to shake uncontrollably. Now supposedly the camshaft bearing is gone, and the truck experience engine failure. I spoke with someone previously, as the issue being repaired hundred thousands of cars were recalled for the same issue. I was told that it wasn’t on the same line, even though my truck was experiencing the EXACT issue and fell under the years. We were placed back on the road with our family, with a vehicle

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.

STEERING
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)

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.

FUEL/PROPULSION SYSTEM
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.

POWER TRAIN, ENGINE
I am writing to formally document serious engine defects I have experienced with my 2021 Chevrolet Tahoe equipped with the 5.3L L84 V8 engine. 1.Crankshaft Failure oMy Tahoe suffered a catastrophic crankshaft failure that required major repair/replacement. oI am aware that GM has recalled certain vehicles equipped with the 6.2L L87 engine for crankshaft and rod-bearing defects. oBased on my experience, the same or a very similar defect has also occurred in my 5.3L engine, which is currently not included in that recall. 2.Valve Lifter Failure oIn addition, my vehicle has suffered from valve lifter collapse—a well-documented problem in 2021–2022 GM trucks and SUVs with both the 5.3L and 6.2L engines. oThis caused severe misfiring, drivability issues, and expensive repair needs. Why this is a concern: •Both failures occurred well before what would be expected of a modern engine. •The crankshaft failure raises a safety risk: sudden loss of propulsion while driving could lead to accidents. •The lifter issue is widely reported by other owners and has been the subject of GM service bulletins. •Taken together, these problems suggest systemic defects in the 2021 Tahoe’s 5.3L engine that have not been adequately addressed by GM. Requested Action: •I ask GM to extend recall and warranty coverage to include the 5.3L L84 engine in addition to the 6.2L L87. •I ask NHTSA to consider investigating whether the scope of the current 6.2L recall should be broadened to include 5.3L engines, given failures like mine. •At minimum, I request assistance in covering repair/replacement costs for both the crankshaft and lifter defects, which are clearly not due to normal wear and tear. Vehicle details: •Year/Make/Model: 2021 Chevrolet Tahoe •Engine: 5.3L V8 L84
