2024 CHEVROLET TAHOE Engine Problems

Purchased new vehicle in September 2024, immediately after purchasing the vehicle the engine had a clanking noise. Took the car back to the dealership where they explained the noise was normal. The car continue to make clanking noise, but noise continued to get louder, took the vehicle back to the dealership for first oil change, verify the noise, and discuss safety recall received on the vehicle. Dealer told me the car was ok to drive. In October 2025, the vehicle loss power during acceleration with immediate re-start. After this incident, took the vehicle to another dealer where they inspected the vehicle again. The test failed and the car now needs a new engine. Car has now 10K miles in the odometer and has been sitting in the dealership for 3 weeks now waiting for an engine replacement.

On October 23 I was driving my vehicle and the airbag light and a message service safety restraint appeared. On October 24 I was in route to take the vehicle to the dealership and as I was merging going to the highway the vehicle turned off, lost complete power threw itself into neutral. I had to drive it over to the shoulder to keep from getting hit. I was able to get the vehicle to turn back on and got it to the dealership. This would be the third time that the vehicle has lost power and completely turned off while driving the first time I took it to the dealership. They said they couldn’t find anything wrong. The second time this happened. I took it to the dealership. They said they replaced the gateway module this third time I took it to the dealership they have called me and said they need to replace the OnStar telecommunication module. The vehicle is unsafe. It is a brand new 2024 Tahoe I purchased it new. The vehicle should not be turning off while I’m driving The same messages consistently pop up the airbag in the service safety restraint. They replaced some kind of console at the top and say that that would fix the issue, but it didn’t because the message came back on again the vehicle idols as if it’s gonna turn off whenever I go to stop the vehicle The transmission stutters are like it’s going into a downshift and it acts like he wants to turn off, but it doesn’t it’s only turned off when I’m driving and then it will just shut off.

Low Oil Life notification on phone. Since L87 recall, an oil consumption test was stopped and the new type of oil has been added to the vehicle 5k miles ago. Had to add a full quart to register on dip stick. Will now start another oil consumption test with a dealership. I am very concerned about my families safety.

I was driving at a normal speed with my family in the car my son has neck pain since that date and the car just turned off i almost got rear ended and didn’t want to start

Driving at highway speeds 70mph, the engine stopped running and vehicle lost all power during heavy rush hour traffic. I was in the middle lane and lost all power breaks and steering, the engine wouldn't restart and I had to force my way to the side of the road. The vehicle only has 21,709 miles and was purchased new less than a year ago. All scheduled maintenance has been performed. The engine is seized and will not restart. There were no warning signs.

When driving on the highway at 75 mph, my vehicle alerted me to add oil. We immediately pulled off the side of the road checked the oil. There was not even a drop on the dip stick. Had to add 3 quarts of oil to even register on the very tip of the dip stick. Please note we were within 100 miles of being due for an oil change. The vehicle is currently at a Chevy dealership to start the process of inspection and do an oil consumption test. This vehicle is my main transportation to take my children to and from school and activities. We live in Larkspur, our children go to school in Monument and we have sports in Castle Rock, so we drive quite a bit. I’m not sure that I’m comfortable with a small fix and using a different type of oil to see if my engine will be salvageable. My questions: Can you confidently let me leave your dealership and guarantee that my family will be safe and know that my engine will not fail due to the recall issues? If my car engine needs to be rebuilt or replaced do you have a comparable loner car until then? If my car engine needs to be rebuilt or replaced can you confidently say this is not going to affect my resale or trade in value? Do you have a recall trade in credit for a 2025 vehicle? I spent $85k on what I thought was a reliable vehicle for me to drive my 2 children around in. My biggest concern is that my engine stops running while I’m on the highway at a fast speed with or without my family. If my husband wasn’t in my car when the oil notification came on, we probably would have lost our engine. How is GM going to make this right and guarantee safety for my family? How is GM going to help with our frustration, anxiety and loss of time dealing with this mistake of selling vehicles with a defective engine? When will I have these answers?

I had a misfire and I bring it to Chevy dealership on 86st Brooklyn ny they did diagnostic And they stated I need a new engine I’m without a car I have wife and kid at home i use my truck to work and feed my family

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.

On one morning w/20 something temperature, Tahoe started and immediately shut down. When restarted, multiple malfunction lights were lit: engine, ABS/brake, steering column, traction control, etc. Reached Onstar for advice to see if Tahoe was drive-able, but only got confirmation of system malfunctions and offered roadside assistance but declined since at home and would call back if needed. About an hour later and several restarts, all malfunction lights finally cleared except engine light, which stayed on for another day or so. Tahoe drove okay during engine light on.

I was driving on the interstate, when the vehicle went into neutral and I could not put it in the drive. I coasted over to the side of the road and then could not get the car out of park at that point. It was towed to the dealership, and I have been told that it has engine failure and needs a new engine.

[XXX], my Chevy Tahoe engine sized up with a warning light no oil pressure and the engine turned off. I was left stranded on [XXX] with no cell phone service and no OnStar. Good thing I had my SXS. I was able to travel to work at the mine site where I work and was able to get cellphone service. I called my wife and she contacted the dealership and they sent out a tow truck from Richfield, Utah. The dealership said that I will have to pay the tow bill that’s is around $900.00 dollars. And my wife asked about a loaned vehicle and the dealership said that they don’t have any loaners. The dealership called me about three days later and said that the engine had spun three connecting rods. The dealership said it would be two months before they could get a new engine and in the meantime I’m still making payments and I bought the truck for work and I’m left using my wife’s car. When I started doing research I was amazed that Chevrolet has known about this issue with their engines and have not issued a recall. This problem has been going unresolved since 2005 and they just keep selling engines knowing that they will fail. My truck has 17,000 miles on it. The warranty is up at 36,000 miles, so the engine is covered under warranty. But l am left a foot and at their mercy. Very frustrating!
