I am writing to formally request a review of my vehicle’s eligibility for Recall N212332040. I own a 2021 Chevrolet Tahoe, which is currently not listed under the affected vehicles for this recall. However, based on the recall description and the symptoms outlined, I believe my vehicle experienced related issues and should be considered for inclusion. While driving down the highway my vehicle experienced power failure leading to a full stop in the middle of the highway, resulting in a 9-1-1 call due to safety concerns for myself and oncoming traffic. The car was later diagnosed with the fuel pump module failure that other vehicles within the same year & model experienced, which were included in the recall. Why mine wouldn’t be included is quite confusing. I respectfully ask that your team investigate whether my Tahoe meets the criteria for Recall N212332040. On 10/20 I sent in a request to the GMC recall department & on 11/11 I was denied anything further. I appreciate your attention to this matter and your commitment to vehicle safety.
Engine, Nov 8, 2025
I am submitting this complaint to the National Highway Traffic Safety Administration (NHTSA) regarding a sudden engine failure in my 2021 Chevrolet Tahoe equipped with a 6.2L V8 engine, which posed a serious safety risk. I was driving on the highway at approximately 65 mph with cruise control engaged. Suddenly, the vehicle lost all power, disengaging the cruise control, and the check engine light began flashing rapidly. I managed to exit the highway safely. While stopped at a traffic light, preparing to turn into a nearby repair shop, the car started shaking violently from side to side, making it difficult to control. I took the vehicle to a Firestone shop and a local Chevrolet dealer, both of which diagnosed massive engine failure and indicated that the engine will most likely need to be replaced. The symptoms I experienced—sudden loss of power at highway speeds, flashing check engine light, and violent shaking—are in line with issues reported in other GM 6.2L engines that have been recalled.  For whatever reason, my 2021 Tahoe, which falls in the middle of the affected model years for these recalls (e.g., GM recall N252494001 for 2021-2024 vehicles with 6.2L V8 engines due to defects in connecting rods and crankshafts leading to engine damage and loss of propulsion), is not included under the broader GM 6.2L engine recall,  although I experienced very similar issues. The biggest safety concern was the engine essentially losing power at highway speeds, which could have led to a crash. I urge NHTSA to investigate and expand coverage if necessary to ensure public safety.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated. In addition, the contact noticed an abnormal ticking sound. The vehicle was towed to an independent mechanic, where the vehicle was diagnosed with a misfire in cylinder #7. The independent mechanic checked the spark plugs and other unknown parts for failure; however, there was no evidence of a failure. The contact was informed of a valve lifter failure. The contact was informed that the valve lifter and possibly the push rods and camshaft needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The contact referenced Technical Service Bulletin: N212353840; however, the VIN was not included. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 87,893.

My tahoe is throwing a low engine oil code and burns through about 2 quarts of oil in between oil changes. other tahoes of the same year make and model have been recalled for the same issue but mine was not.
Power train, Oct 24, 2025
My 2021 Chevrolet Tahoe recently displayed a warning message that said “Service Transmission – May Not Be Able to Shift Soon.” The message appeared at approximately 132,754 miles. Since then, I’ve noticed delayed and rough shifting between gears. The vehicle still drives and shifts into gear, but the message and behavior are concerning. I have an appointment scheduled for a diagnostic inspection on Tuesday, which was the earliest available. I have not yet received a confirmed diagnosis, but I’ve seen that many other 2021 Tahoe's and similar GM vehicles have experienced the same transmission problem and were included in recalls. My vehicle’s symptoms match those reports, though my VIN was not included. This situation makes me nervous because I drive with my four children daily. Even though the vehicle hasn’t completely lost the ability to shift, a sudden failure while driving could put my family and others on the road at risk. The warning itself suggests a potential failure is coming soon. The vehicle has been properly maintained and has not had prior transmission work. I’m reporting this because it appears to be part of a larger pattern that should be investigated to determine if more vehicles need to be included in GM’s existing transmission recall.
Fuel/propulsion system, Oct 20, 2025
While driving my vehicle shut down. It will not longer crank. Had to have it towed. I am told that it’s the fuel pump driver control module. I carry my two children in this vehicle daily.

The head rest in the third row seat is broken and will not remain in the up position when the seat is up. This is causing a safety risk in that there is no safety for passengers in a rear end collision. There is already a recall that Chevrolet has issued for other Tahoe vehicles; however, my VIN number has not been added to that recall. I am requesting to have my vehicle's VIN number added to the already existing recall.

On the morning of 1 Oct, I had left the house here in Cedartown GA to head to a meeting in Atlanta with a customer. I had started the truck 15 minutes before departing just as we have always done to our vehicles over the years to allow them to warm up properly. I departed Doyle Rd onto Hwy 27 South heading towards interstate 20. About 15 miles from the house I was at a steady cruise speed of 45 MPH, no traffic, acceleration or deceleration and the stability control system light came on, one second later the engine light came on and the engine all of a sudden started making a loud grinding and clunking noise. I was on the inside lane so let the car pass next to me and started to pull over onto the shoulder of the road. I immediately shut off the truck, popped the hood and got out to inspect what might have happened. There was no smoke, I checked all the fluids and all were at the normal ranges. The engine oil was at its full mark as well. The oil was just changed a month early and still of the same color as it was new. After checking, I got back on the truck, attempted to start and it ran for a few seconds then I immediately shut it off after hearing again the loud noise. A Polk county police officer stopped to check on me and offer assistance as well as some tow companies to call. Eventually after about at hour a tow truck showed, we tried to momentarily start the vehicle so it could be put in neutral but the engine had locked up. I’m glad I got off the road when I did, otherwise I feel I could have been driving and experienced that sudden lock up and loss of control which could have been a serious accident with log trucks up and down that highway all day long. This vehicle is my wife’s primary vehicle and always has been maintained to a T just like all of our GM vehicles have. My daughter just graduated and drives our passed down 2005 Tahoe with over 300k miles that we bought in 2006. This has never happened to us and I feel it is a serious safety issue on the 6.2

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, Sep 25, 2025
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.

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.

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.

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.

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.
