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

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.

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.

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.

I bought this 2023 Chevy Tahoe rst brand new from the dealer and about a few months of owning it I noticed that the truck was needing oil before the next oil change. It’s as if it was consuming itself. This continues for month until last week when the truck died on me. I was able to jump start and everything worked fine for a day. The next day things got worse. I was on the highway and truck started shaking and giving off all kinds of codes. I took it to dealer and they said I needed a new battery but that there was also an engine problem. I bought a new battery and none of the messages on dash resolved like I was told. The truck is u drivable motor is knocking and was even making loud popping sounds. Of course my truck just hit 64,000 miles so gm is saying I’m out of warranty. I should not be having these types of issues on an almost brand new truck that I’ve owned 2 years. Engine light is flashing and dealer said this means major issue.

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!!
