There is an unusual lifter/ticking noise coming from the valve covers on my vehicle. The vehicle is scheduled to go to the Chevrolet dealership on the 15th of this month but it sounds like the numerous other gm motors that have the failing lifters.

I filled my car up with gas and turned it on and it started shaking. Several warnings popped up on the dashboard screen including, service esc, service traction control, and forward collision system unavailable. My cruise control was disabled I had to hold my foot at an angle to keep the speed at 45-50 mph, causing it to take 10 hours for me to get home from austin to dallas. The check engine light was on the entire time and flashed for the last hour to hour and a half. I was unable to pull over at that time because it was dark and I was in the middle of nowhere by myself. The next day I turned my car on. The only thing on was the check engine light, is , however , around 1 pm that day it started doing the same thing. I drove it from my patient's house in allen to galleria Chevrolet in dallas. They told me my battery was too low to run diagnostics and I needed to replace it. So I bought a battery and brought it to them. They replaced the next morning and told me there were no codes showing up so there was nothing wrong with my car and it was a fluke. Exactly one week later the same thing happened to my car. I called the dealership and they hao it toewd to the service dept. After I repeatedly called them to check on the status of my car, they told me it was the fuel injector #1. They then were able to apply for a loaner car for me as I am a hospice nurse. These are same exact issues that the gm 6. 2 l engines are having with the recall they just announced. I have a 5. 3 l engine. I am afraid to put my kids in my car. Please help get gm to take responsibility for this!.

While traveling on the highway one day, my 2021 Chevrolet Tahoe began warning lights on the dashboard. Shortly after, it running roughly,, and jerking, so I pulled over to investigate. There no visible smoke, so I drove to the nearest auto parts store, where they ran a diagnostic test that returned a code of p0306. I then took vehicle back to the dealership where have always received oil changes and repairs. I have never visited any other dealership, relying on certified gm/Chevrolet dealerships. After inspecting the vehicle, they informed me that the lifters needed replacement advised that it would be best to replace the engine entirely. Upon further research, I discovered that issue has been affecting many people in our area and across the united states. This needs to be addressed, as the vehicle is only three years old, purchased brand new with zero miles, and I have not done anything out of the ordinary to cause this problem. The vehicle being 70,000 and 12. 000 for repairs is insane.

My vehicle has a little over 15000 miles on it. On Thursday April 3rd, while driving 35 mph in town, my rpms shot up to 4 and the vehicle would not respond to accelleration. A few seconds later the engine light appeared. I managed to get the vehicle home going no faster than 42 mph off and on. Upon arriving home I realized I had no reverse in the vehicle. I immediately called the dealership and was told to bring it in. They didn't look at it until the following Monday April 7th when they determined the transmission control module went out. Gm told them they "couldn't find that part anywhere". Thr vehicle still sits behind the dealership and gm has no answers and has already hinted that it may be at least 60 days. This is unacceptable.

The transmission out of no where started to hard shift from 2nd to 3rd gear then making noises. Spoke with a mechanic who specializes in transmission he had 2 other Tahoes same year same problem that are in front of mine to work on.

Vehicle shutters when downshifting/slowing. Most commonly at cruising speeds between 40 and 50 mph, but does occur at lower speeds as well. Vehicle can be felt vibrating/shaking consistently every time it is driven. Was taken into a dealership, was not adequately diagnosed as it was only test driven 1 mile per the paperwork and they could not duplicate the issue and was told they were "in the business of making money to repair vehicles" and this was a warranty repair. While leaving a gentleman was walking in and happened to have the same type of vehicle and asked my husband what we were there for, turns out he was having the same issues. The vehicle shuttered the entire drive home after leaving the dealership and has continued since.

My family and I were returning from vacation from florida to our home state, north carolina, when our new Tahoe with 5700 miles started to act strangely. We hit bad traffic leaving florida so there was plenty of stop and go type maneuvers. At one point, the vehicle turned itself off and put itself in neutral while we were thankfully going a slower speed due to traffic. I was able to get off the shoulder near the [xxx] and restart the car. It ran fine after restart until it started making a clanging type noise from the engine bay. We stopped again and checked temperatures and fluids and the clanging stopped. About 30 minutes later the clanging and a guttural noise began to occur from the engine bay and the transmission would not shift, keeping the vehicle at/around 4,000 rpm at 60mph. We were able to get the vehicle to a nearby rest stop. My wife, 3 children, and I were put in harm’s way due to gm’s faulty product and poor quality control. To have your vehicle shut itself off and/or not shift, especially on the interstate, is incredibly dangerous to the occupants of the vehicle as well as the motoring public. It is important to note that the vehicle never displayed any warning lights of any kind before, during, or after the incidents described. Almost two weeks later, Chevrolet (cooper Chevrolet s. C. ) has not even diagnosed the vehicle. They have told be that they will more than likely have to tear the motor apart to figure out the issue(s), confirming that the problem has been replicated by their technicians. The Tahoe is equipped with a 6. 2l v8, a motor with well documented issues. The Tahoe is currently located at cooper Chevrolet in walterboro north carolina. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Driving on hwy at 75 mph and needed to brake. While decelerating and still moving, engine shut off, dashboard dinged and message said to press start. Vehicle put itself into neutral. Happened twice while driving on highway. Car currently in shop. Gm stating transmission valve body needs to be replaced. Tahoe only has 28k miles. Part is on back order.

Vehicle down shifted hard and dash board lit up. Wouldn’t shift any higher than 4th or 5th gear. Fortunately we were only going about 35mph. If we would have been on the interstate as we had been the 2 previous days on our trip to florida it could have been deadly. Brought the Tahoe to ron anderson GMC Chevrolet in yulee, florida on 3/18/25. The transmission valve body is the problem. As of today 4/11/25 we haven’t heard another word and returned home to michigan 3 weeks ago.

I have a 2021 Tahoe with 68,000 miles on it. On March 14 my transmission started slipping while driving. The rpm would rev up, the car would jerk forward and then the rpm would fall back down. Did this to me 6 times while driving. I got my car home, called the dealership. Went to drive it to the dealership and the car would no longer go in reverse. Had to have the car towed to the dealership.

Transmission is overheating and forcing the truck into limp mode.

While driving down the highway, the vehicle suddenly experienced multiple issues. The headlights went out, the vehicle would not continue to accelerate, and all interior lights shut off. The vehicle then shifted into neutral and stalled. There were no warning signs or indicators before this happened. Our safety was at risk as we barely managed to pull the vehicle over to the shoulder, with no working emergency lights. The highway had no street lights, and we were constantly worried about being hit by other cars since our vehicle was nearly invisible without the emergency lights. The malfunction left us stranded more than two hours from home. We had to have the vehicle towed to a Chevrolet dealership for inspection, which was also over two hours away. Prior to the failure, there were no warning lamps, messages, or other symptoms—everything happened suddenly without any notice.

Faulty valve body safety was put at risk, I was traveling on a 4 lane road at 45 mph when my vehicle experienced a significant jump in rpm with immediate loss of propulsion. I immediately drove to the dealership as the incident was frightening. The vehicle was also not able to go into reverse. This valve body failure issue has been confirmed by the gm chevy dealership, and gm corporate executive services. My vehicle has been undriveable and at the dealership since 3/4/25. This is a known issue with gm, parts are not available and are back ordered with no eta on when they will be available. Even with a replaced valve body it is likely the vehicle will have future transmission issues &/ additional valve body failure. Please strongly consider a recall related to this known issue and safety concern.

Purchased 2017 Chevrolet Tahoe on 1/15/2025 with 50,647 miles on it. At exactly the 40 day mark, we noticed a problem when the vehicle began downshifting. When slowing down to stop at a red light, we could feel the transmission begin jerking as it shifted down and the check engine light came on. It has been taken back to the dealership (where we bought it), 5 times as of yesterday and they cannot fix the problem. The engine idles rough, downshifting is extremely hard, check engine comes on and off sporadically. The transmission temperature goes up and the dashboard lighting dims intermittently. This vehicle appeared to be in extremely good physical condition with very few miles, that's why it was purchased.

2022 chevy Tahoe with 32,292 miles of in-town and highway driving, never any towing. Perfectly maintained on time. Suddenly started to not respond to acceleration, and jolting, then would not reverse. Transmission valve body has already gone out. Gm acknowledged the problem. States there is a national shortage of this part. There is nothing they know of being done about. Park the vehicle and wait for a part to become available. No eta, but 2,200 of this part have already been requested recently.

While driving and accelerating the transmission malfunctions and wont shift so as I try to accelerate the car stops accelerating and just goes very slow. This put us at risk as cars were coming fast behind us. The problem happened 3 times before taking it to the dealership where they knew exactly what the problem was because it has happened to so many others. The warning light that came on was the engine light and a message that read "reduced acceleration drive with care".

Traveling down the highway at 65 mph the engine/transmission started bucking and you could hear the rear wheel lock up. The vehicle then would not shift and reduced the speed to 55mph. Check engine light came on. Chevrolet is telling me the valve body needs to be replaced but keep driving it because it is on national backorder. After doing some research gm is hiding the issue and keeps installing faulty valve bodies. The gm fix is that they programmed the transmission to reduce speed when it notices excessive wear. Gm is not standing behind the issue as it has been like pulling teeth to get a loaner vehicle.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while her husband was driving at an undisclosed speed, several unknown warning lights illuminated, and the engine made knocking sounds. The message "service transmission" was displayed. The contact's husband pulled over and turned off the vehicle. The vehicle failed to restart immediately. The vehicle was taken to the dealer, who replaced the camshaft retainer, valve tensioner kit, gaskets, seals, lifters, engine bolts, rods, and pipes; however, the "service transmission" message displayed again while driving. The dealer was made aware of the failure, but the vehicle was not yet diagnosed or repaired. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The failure mileage was approximately 89,678.

I was driving my 2023 Tahoe on the interstate, in the far left lane. I had my wife and 2 kids in the car. Suddenly I noticed the air turned off and the dashboard screen went blank. I noticed that the car was now in neutral and the accelerator was not providing any response. I put on my hazards and started to merge across 7 lanes of highway without using brakes because we were going up a hill. We lost momentum in the second to last lane and could not move. The Tahoe then switched to park and the electrical system kept shutting off and rebooting. This also resulted in the hazard lights turning off for brief moments in time, so it was not effectively alerting other travelers of our dysfunction. (this repeated for the next 30 minutes until the battery died. ) during that 30 minutes we were stuck in the lane with traffic buzzing around both sides of us honking and people screaming at us. My wife and 2 young children were upset and crying from the commotion. Poluce and emergency response team arrived, flagged traffic and drug the vehicle off the road. Car was stuck in park, with no ability to move to neutral. So tire rubber was smeared across the last 2 lanes and into the right shoulder. Later a tow truck arrived and hauled to dealership. The car had ~11,000 miles and bought the vehicle 2 months ago. This should not happen with new cars.

When slowing down and accelerating there is a shutter and a jerk to my transmission. While I am driving the shuttering is sometimes so loud I can hear it over the radio and it is a vibration motion.

Valve body for 10 speed transmission suddenly malfunctioned while driving on I-95 at 60mph causing rear wheels to lock up for couple of seconds. Then, engine rpm went to 5000. Error message displayed"reduced acceleration, drive with care" and "unable to shift soon, service transmission soon". Upon taking to dealer, service advisor mentioned that it could be valve body issue. Which is very common for these vehicles. After diagnosis from dealer, there were two codes: p0770 and p0776. Upon some research it was found that these issues are indeed very common for 10speed gm transmission. But, gm hasn't done much to address it. Gm acknowledged the issue in their oct, 2023 bulletin.

1st. While driving at highway speeds my vehicle disengaged from adaptive cruise control when no cars were in view of sensors. However, cars were behind me, making it a little scary. Happened once but I haven't had my vehicle to know if it would happen again. 2nd. Car has a vibration at speeds of 30 to 40 mph. Vehicle has literally been at dealership since February 10th, 2025 with no eta for valve body in sight.

I was driving along the highway at 11pm when I the vehicle started shaking and I heard strange sounds coming from outside the vehicle. I pulled over to inspect and realized it was coming from the engine bay. The engine was making knocking, rattling, and belt slipping noises and the entire vehicle was shaking and the engine also stuttering. I was able to drive the vehicle to a nearby plaza where I had it towed the following morning. There were no warning signs, the vehicle ran properly up until this occurred. The dealership inspected it and told me the engine needs to be replaced and it was likely that a rod bearing that went bad. This happened nearly 2 months ago and I am still waiting for a new engine.

The vehicle shudders and shakes going down the road causing a safety hazard when failing. The transmission fluid has been changed multiple times and yet the transmission remains unstable with no errors or check lights appearing. When taken to the repair shop it seems there is a large number of failures for this transmission type.

My vehichle will not go in reverse my wheels are locking up and also my car is going over 6000 rpm when going down the highway and not wanting to shift gears where it is a safety concern for myself and my kids well being.
