At approximately 19.000 miles when the car sits for an extended period of time, at the first start up, blue smoke comes from the exhaust tail pipe. Brought it to the dealer and they said that, that was normal. With the issues they are having with the engines, I wanted this to be noted, because blue smoke is indicative of either bad piston rings or bad valve seals. This should not be happening on a vehicle with 19,000 miles and have oil changes at every 3000 miles.
We were driving on a busy interstate in Knoxville, TN on a Sunday. We were 2 hours from home and my 2023 Tahoe basically went into limp mode while I was in the fast lane and the check engine light came on. No warning in advance. The speed reduced, which backed traffic up, and put me and my 4 children in danger. We finally got off the interstate and the vehicle had to be towed in to the nearest dealership. I had a friend drive us to enterprise where they put us in a Jeep Grand Wagoneer. On Monday, I received a call from the dealership stating they had good and bad news. The good news was the repair is covered by warranty but the bad news was it will be 2-3 months before they can get the part. The part is on back order and several people are waiting ahead of me. The said part is a valve body for the engine/transmission. The dealership also informed me that warranty will not cover a non-GM vehicle and that they will only pay for a rental up to 44.00/day. It’s not my fault the part is on back order, nor that enterprise gave me a non-GM vehicle. Also, I have a family of 6, which is why I have a Tahoe and I cannot be put in a small sedan. My children play sports, we have upcoming vacation, and quite frankly, I didn't pay 90,000.00 for a vehicle to be placed in a vehicle that I don’t feel is safe for my family. If I had wanted a sedan, I would have bought one. GM should take better care of their customers, especially when something is like this is not the customers fault!!! I have contacted GM and have been told I will be called back by a supervisor each time I talk to someone. This is unacceptable!!
I was driving on [XXX] thru Atlanta to meet my husband in Adairsville, Georgia, and my car started squealing like a belt was squealing and then it started making a loud knocking noise and shut off I was able to get it to the shoulder to see what was going on, when I realized it was in the motor I was about half a mile to the next exit as I did not feel safe being on the side of the road managed to make it to the truck stop after it cut off several times just imagine if someone was close behind me when my Tahoe kept shutting off it could have been a very bad accident called gm roadside assistance and had vehicle towed to nearest dealer they couldn’t look at it so my husband loaded it into the back of his lowboy trailer and took it to hometown dealer where I bought it from Tahoe only had 22599 miles on it and I paid over 90k for this I feel like we should be compensated for this and the downtime of not knowing when I will get it back INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
2023 with 34,000 miles on the 6.2 engine. Shutoff while driving. Engine is bad and will need to be replaced. GM should be forced to do a recall
Started having an issue a few weeks ago with the vehicle shutting off while driving for no reason without warning causing a very serious safety concern. This issue seemed to stop until one Saturday when i started the vehicle i noticed a small tick. This ticking sound continued to grow. The vehicle then shut off again with warning while driving. 7 days had gone by since the first episode. When I started the vehicle again there was a very pronounce rapping and it sounded like parts inside the motor were coming apart. When I arrived home i called Onstar. They did a diagnostic twice and said the motor was not showing any codes and running perfect. I had it towed from my house and upon inspection the motor is blown with 10,000 miles
Engine failure due to rod bearing failure, without warning at 16,500k miles. It is available for inspection if needed. Currently is at dealership waiting for new engine. The vehicle shut off while driving at 40mph forcing me to have to stop in the middle of a roadway without any shoulders or turn offs. The problem was diagnosed and confirmed by a certified Chevrolet dealership. The failed engine will be sent to GM by the dealer. There were no warning lights prior to this incident or after.
The contact owns a 2023 Chevrolet Tahoe. The contact stated that upon starting the vehicle, there was an abnormal sound coming from the engine compartment. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the dealer, who then determined that the sound was the lifters tapping. The contact was informed that all 16 lifters needed to be replaced. The vehicle was repaired, but the failure reoccurred. The vehicle was taken to a different dealer, who also diagnosed the vehicle and determined that the failure was with the lifters, and informed the previous dealer might not have been repaired the vehicle properly. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 28,000.
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.
Vehicle broke down on 12/1/2024. Had it towed to the nearest dealership. Dealership claimed that gasoline was pumped into the tank. We knew that wasn't the case. I called the store we last used for fuel and spoke to the manager. She was able to pull my wife up on surveillance and verified that she pumped diesel fuel from a "diesel fuel only" pump on 11/21/24. We also verified that the fuel in the holding tank at the store was actual diesel fuel. My wife purchased 23.45 gallons of diesel fuel. The tank size on this Tahoe is a 24 gallon tank. We had burned half of this fuel before the vehicle broke down. We also verified that no one else had complained about the fuel from the store. Dealership said it needed a new engine. We had it towed to another dealership for a second opinion, but they couldn't verify what happened because the 1st dealership had cleaned out the fuel system. I called GM but they won't help because they are going off what the 1st dealership claimed. Vehicle is still under power train warranty, but they won't fix it. This vehicle left us stranded on the side of the road. Insurance was called and a representative did go and look at the Tahoe. He called back and said that the issue does not fall within our policy.
First the front collision warning systems kept coming on and off. Then the engine died on the highway and I had to restart. I drove a little further and it died again and would not restart. I had it towed to the dealer and they are telling me the engine has seized and needs to be replaced. I have 40,000 mile and the car is 2 years old. It was very dangerous to have the car die twice while at speed on the highway.
Repeated issues with the infotainment system had to be replaced 3 times to date. The motor blew at 49,000 miles 3 weeks ago. The replacement motor is on back order and it is very difficult to get a loaner vehicle, not to mention having to make a payment on the vehicle that I don’t have to use.
Traveling in left lane of [XXX] . Vehicle screen went black and car lost all power. No warning lights. Vehicle towed and inpected by GM dealership and determined that the vehicle needed a new engine. Vehicle maintenance records confirmed proper maintenance was done. Vehicle only 13 months old. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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 we first purchased our 2023 Tahoe the engine was making a tiking noise we took it back and they told us it was because it was brand new time past engine always needs oil when we drive it u have to press gas pedal it also has electrical problems back camera turns on and off . Brake sensors don’t work . I almost had a bad car accident due to the engine that it had stop because it said reduced power while I was on a highway . I lost my son 3 yrs ago in a car wreck . I don’t want no more accidents so please help me figure some out with my Tahoe . I also went to dealership and they directed me to a manager . Manager never help never called back or nothing we bought truck at friendly Chevrolet
Engine, (6.2 liter V8), quit without warning at highway speed, nearly causing head-on collision. Engine wouldn't re-start and needed to be towed to dealership on flatbed truck. Vehicle also wouldn't shift into neutral requiring it to be dragged onto flatbed. Chevy dealer states new engines are on backorder with no expected repair date.
While slowing for a red light my vehicle shut off, completely powered off. I had to press the ignition start button to turn it back on. I pulled to the side of the road, then two messages flashed on the dash screen, Service Transmission and Service Brake Assist. I called and scheduled a vehicle service at a local Chevrolet service center. After the service center evaluated my vehicle (in their possession for 72 hours) they stated there were no diagnostic findings and they could not replicate the issue. A vehicle randomly shutting off with no identifiable or repairable issue is a public safety concern.
I was driving in the fast lane and all of a sudden my car went into neutral. Thankfully, my children were not in the car and I was able to merge over safely to the side of the freeway. after as I barely pulled off the car completely shut off. I tried to turn back on several times but would not start back up. I had my Tahoe towed to the dealership, and they told me the engine seized up and was a failed engine. Dealership ended up ordering another engine and it was missing some sort of plug that failed and had to replace again!

Our engine (v8 6.2 liter) failed with out warning while my wife was driving. She said that while driving all of a sudden the dash started flashing telling her to restart the engine. The car just started shutting down. She had to immediately pull off into the median and barely made it out of the fast lane when the car stopped. She was so close to the fast lane that there wasn’t enough room for a person to stand without being hit. We had our Tahoe towed to the closest dealer thinking maybe it was an alternator. The dealer confirmed it was a failed engine and that our vehicle is the third vehicle on their lot with the same failed engine. All of the failed engine vehicles have right at 40 k miles plus or minus 1k miles. The only problem that we had noticed before the failure, happened that morning when I took the Tahoe to fuel up for my wife prior to her leaving. I noticed the engine cranked slow for a second before it started. I thought maybe the battery is just getting weak and that as she drove it that day, it would charge the battery. The exact failure as I understand it from the technician is “ the 5th cylinder failed in the lower half of the engine.” Apparently this is failing because the bearings weren’t properly seated during manufacturing.
On Sunday January 12, I was driving the vehicle on the highway with my cruise control on. The engine started missing the speed dropped a bit as the cruise control would not hold the speed. A mile or so later the vehicle engine started knocking with a metallic sound. I pulled over at the next exit and stopped at a store to look at the engine. There was nothing loose and a deep metallic knocking coming from the engine block, so I shut off the vehicle and called OnStar. At no time did any warning lights or other indicators come on. The gauges were normal. They/OnStar indicated I should not drive the vehicle, and they will tow to nearest Chevy Dealer for service and give me a $50 credit to take a Lyft to local airport to get a rental car. I was almost 4 hours away from home as I was travelling. After a week of turmoil with the local dealership I was told the vehicle needs a new engine. There is no ETA on the new engine as GM has to build it and has parts shortages. This was 5 weeks ago. I have been driving a rental since and there is still no indicate from the dealership about what happened or why. The vehicle is a 2023 and still under warranty but I am having to pay for the rental and request reimbursement which hasn't happened to date. There is very little information available, and I am in no man's land without a vehicle, so I have an open ended rental situation.
The vehicle shut off on the expressway causing a very dangerous situation. After several attempts it would not start again. I had to have the vehicle towed to the dealer and they advised me the engine has seized up. Most likely they told me the engine blew and will need replacing.
While driving the vehicle, the transmission stopped shifting and the engine shut off. There was no warning.

6.2l engine catastrophic engine failure with appt 17,000 miles on odometer. Kendall Chevrolet of marysville Washington has new engine on back order.
1st incident- Engine had a bad lifter and cam shaft with 46,000miles. When this happened I was going through a railroad crossing, if the failure was bad enough and locked the engine up I would have been stuck on the tracks with my family. This issue could cause the motor to lock up if the lifter or cam shaft had a more serious failure. Dealer confirmed the lifter and cam shaft were bad and replaced. the engine had a vibration 2 weeks before the failure but the dealership could not identify or duplicate the issue. Vehicle was in the shop for 35 days to repair. 2nd incident- Parking brake and brake system locked up and would not release until the vehicle was reset. Scheduled vehicle to be towed in and the brakes locked up again while loading the vehicle to tow. Dealer is still troubleshooting the issue after 5 days. Errors on screen "Forward Collision System unavailable, Brake system failure 43mph top speed, Service steering column lock, service traction control, Service ESC, Service Brake Pad Monitor" If this happened while on the highway it had the chance to cause a serious wreck.
With 63,000 miles the vehicle experienced catastrophic engine failure on a freeway. This resulted in loss of power with no ability to get the vehicle to a safe location. It was determined that the #7 crankshaft bearing was the cause of failure and the compete engine was replaced as a result.
