I am experiencing loss of power just like the recall shows for campaign 22V036000 powertrain. Engine stall in the middle of the street just like it shows for the fuel system 21V73 9000. I have stalled in the middle of the street including today four times and a month. The dealership can-??t seem to find what-??s wrong. Nor other places. I don-??t think they are looking hard enough at the dealership. I almost got killed by another car going at least 65 mph while I was stuck in the middle of the street at a stoplight. These are all different days. While working and people in my car.

As a traffic crash reconstructionist, the issue is a MAJOR SAFETY ISSUE. My wife was exiting a residential driveway when the vehicle started to stutter and immediately shut down with no power or any capability to get the vehicle off the road. The shutdown caused the blockage of a residential street on a Friday afternoon, until the correct tow truck arrived. This was due to the fact the vehicle could not be moved due to not being able to start the engine nor the ability to place the vehicle into neutral, without starting the engine or crawling un der it with tools. It was determined the fuel module went bad. There was no warning of the failure of the component. Luckily the shut down of all components of the vehicle did not occur on a high speed or highly traveled road since I did not have any control of the vehicle after the fuel module failed. This is not the first report of the issue to NHTSA. Hopefully something will happen to find a fix to put the vehicle in neutral without tools, for the safety of the motoring public.

This is the second engine I-??ve had replaced since I bought the vehicle in December 21, 2023. The first engine failed in August of 2022 while I was driving on the highway. The vehicle began to smoke and shut down while I was driving on the highway. The vehicle shut down and I had to use the current momentum of the vehicle to pull over to the shoulder. The vehicle would not come out of gear and would not restart. I complained of transmission problems ever since the engine was replaced. The service department escalated the concerns to the GM engineers who never gave directions to check the transmission fluid or physically check the transmission. January 24 of this year I was on the highway driving to work when the vehicle again shut down. The dash stated restart the vehicle. While in motion the vehicle was trying to shift to neutral. I informed the dealer of this message and they claim they took note of it. With the vehicle not being able to start or move out of gear the tow truck had to drag the vehicle onto the bed of the tow truck. This also occurred on the first engine failure as well.

The failed component was reported to be the Coolant Surge Tank. This component cracked and begin to leak engine coolant causing the vehicle to overheat and become undrivable. This failure also lead the inoperability of the heating system inside the cabin of the vehicle. The failure of this component is widespread knowledge in the Chevrolet Tahoe/Suburban and GMC Yukon ownership community. In some cases dealerships are purposely marking up the cost of replacement components due to the scarcity caused by this failure and production issue within GM. The only symptoms of this issue were overheating and inoperable cabin heater. No warning lights or messages were displayed.

Vehicle is sputtering and jerking while driving When slowing to a stop vehicles engine will shut off. I do know that the 2021 Tahoe has recalls on the fuel pump issues but not sure why my vin number isn-??t covered under this recall. This is a 2 year old vehicle and already has recalls on this year model on its fuel pump. At this point it is barely driveable and is a danger for myself and my family to drive.

On Wednesday, Sept20 2023 I was traveling eastbound in the passing Lane on interstate 90 in New York when my Chevy tahoes motor began shaking violently, chugging, and losing power. The check engine light illuminated. The engine stalled as I frantically tried to move to the berm. There is a lot of large semi traffic on that road and I had a difficult time maneuvering safely without power to get onto the side of the road. I was unable to move completely into what I felt to be a safe area. I continued to try to start the motor after about 10 minutes I was finally able to get it started and move it to an exit where it was towed to community Chevrolet in Meadville Pennsylvania. The Chevy dealer at this point has told me it is a fuel pump problem and they are on back order and there is a strike by the auto workers. They are unsure as to when I can have this problem remedied with the parts that are needed.

Wife was driving home from work, vehicle started with no issues and she did not notice anything abnormal as she started her commute home, roughly 20 minute commute. She noticed the vehicle was vibrating, mildly at first and progressively getting worse. When she came to a stop at red light, she noticed the vibrating was worse at idle. She did not note any warning or cautions, she contacted me, i advised her to attempt to make it home. Once the light turned green, she accelerated and noticed the vehicle smoking, she pulled over into a parking lot, parked and shut it off. By this time all the warning in vehicle were flashing, battery and oil pressure gauges were fluctuating, check engine light was flashing, traction control, and other adaptive sensors i.e. blind spot, HUD where signals were displayed as off or not functioning. I was able to drive the vehicle to.4 miles to the dealership service center where we purchased the vehicle from in 2021 brand new off the lot. This occurred on 6 September 2023, still awaiting final diagnostic from from service department. They think its the lifter on the engine that failed, but they have disassemble engine to make exact determination. Once I receive diagnostic/invoice details I can provide that, luckily vehicle is still under warranty.

We were driving down the road and as I tried to accelerate the car would not go. Then I realized the car said push to start. My husband tried to push the neutral button and told me to restart it but I said you have to push the brake. All this is happening as we are coasting down a main road with speed limits of 55mph and my family is in the vehicle (including 2 toddlers in the back seat). Once we coast to a gravel area off the road I push the brakes and try to restart. My dash goes all black and I try to restart. It tells me battery low push to start. The starter engages and stays engaged until I push the start button again to turn off. The screen tells me it is shutting down functions to save battery. The check engine light is on. We tried 3x with same results. Finally we get out and my parents come to us. Within 15 mins of the initial incident, my husband and dad get in and start my vehicle. My dad suspected the fuel pump. The fuel was right under 1/4 tank but not low enough for the fuel light to be on. They drove to the fuel station, approximately 2 miles away, filled up the tank and drove it to an auto parts store who connected it to a diagnostic machine and it read fuel pump. They drove it back to my home, approximately 2 more miles. The check engine light is still on. I will call the dealership tomorrow. The vehicle has 23,000 miles and is still under manufacturer warranty.

I was driving down the highway and my car simply stopped moving, pressed on the gas and nothing. Had it towed and the dealership said it was the fuel pump power control module which there was a recall on but I never received it. I was in a very dangerous situation and I am not happy.

I bought the vehicle (a Chevy Tahoe) brand new in 2021. After 7,000 miles the lifter in the motor broke. The top of the motor had to be rebuilt to accommodate a new lifter. Now, with 24,000 miles on the vehicle, another lifter just broke, so the motor has to be taken apart again. I am certain GM knows about this problem, as (the lifter issue) it is all over the internet, but GM will not issue a recall of the defective lifters. I would be very interested in joining a class action law suit to force GM to recall the defective (lifter) parts. In both instances when the lifters broke, there is no warning! The engine looses power and the vehicle "bucks and shakes". It is just a matter of time before this issues causes sever bodily harm because of this massive engine failure. I have all of the repair documentation.

On three (3) different occasions, I put the SUV in Park and the car engaged, and the "P" lit up as engaged. As I took my foot off the brake, the SUV went into Drive and rolled. This last time, the SUV did this at my kid's school Ater putting it in Park, I took my foot off the brake and turned to get the kids unbuckled, and my foot accidentally pushed the gas pedal. The SUV went into drive on its own and the SUV drove over the sidewalk hitting a rock staircase causing an accident with all 4 kids in my SUV. This is the 3rd time, and I don't know what to do about it. Thankfully there were no kids in front of the SUV.

I have an on going problem with the emissions system on my 2021 Tahoe. The vehicle discharges raw diesel fuel and DEF from the exhaust tail pipe during cold startup. This discharge is overwhelming and is so strong it can be detected by smell from over fifty feet away. In addition to this issue the fumes enter the inside of the vehicle and at times it is so bad you need to open the windows. I believe this problem is unsafe as it poses a fire risk and a CO exposure risk to the vehicle occupants. The vehicle has been in the shop repeatedly for the past eighteen months with various parts replaced. To date none of the repairs have fixed the problem. In February GM issued a statement saying that this is normal operations.

While driving in traffic the car shut off, engine stopped. When the car stopped it went into park. Could not restart the car. Starter worked and engine started but ran very rough then stopped several times. I could not completely shut off the car in an attempt to basically reboot. Car had to be towed to the dealer.
