2024 CHEVROLET TAHOE Engine Problems

Dealer checked the 6.2L motor for known defects. It "passed" inspection on 11/20/25 and got the thicker oil (OW-40). The engine lost propulsion ("died") 3 times on a 55mph State Highway on 02/09/26 with my 4 year old in the car with me. It died and came to a complete stop in one lane and would not re-start initially with cars almost rear ending us and needing to aggressively swerve to avoid hitting us. After 4 or 5 attempts it started again (making terrible grinding noises) so I could get it off the road before it died again. It started again to drive home on the back roads approximately 1 mile. Low oil pressure and check engine lights came on. I also received notifications from onstar and from the my Chevy app that there were severe motor or transmission problems. I scanned it with an OBD II Scanner and it...

Driving on the New jersey Turpike I passed through the ez pass tolls traveling west bound on Bayview Ave bridge, the vehicle shut off without warning. No check engine light or noise, just no propulsion or anything. Dead in the water. Vehicle would not restart.

The vehicle in question had approximately 5000 miles when low oil light came on, it was 2 quarts low. this was after the first oil change at around 3500 miles. I had the dealer do an oil consumption evaluation. They check the oil every 500 miles and confirmed it was using 2 quarts every 2500 miles. They informed me GM says this is normal. I cannot disagree more with that claim. GM knows they have a problem with the 6.2-liter engine. I have researched the issue and found they have a problem with the crankshaft machining and the oil delivery port beveling that delivers lubrication to the connecting rod bearing appears to be too large that causes the motor oil not to consistently keep the bearing lubricated. This causes the engine to be an "oil burner" and premature failure of the bearing. They think putting a heavier viscosity of oil...

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...

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...

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...

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...
