2023 Chevrolet Tahoe Engine

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.

I was driving down the interstate and with the no warning the vehicle would not accelerate any longer and tried to coast onto the exit. Totally stopped blocking all traffic on the exit. Could not crank the engine or at least put in to neutral to push out of the road. Had it towed to dealership and they said motor had seized up, connecting rod bearing seized on crankshaft causing extensive metal contamination throughout engine. Wanted GM to buy back the vehicle but would not. Only replaced the engine.

On [XXX] while driving on the highway near Wash DC engine stopped, went to neutral. Would not start again. OnStar towed vehicle to Koons Chevrolet GMC Tyson in Vienna VA. 703 448 7221. On Tuesday [XXX] Koons Service Dept. looked at vehicle and determined that it was a thrown bearing and needed a new engine. There are 28,712 miles on vehicle. You can inspect if desired. Our safety was extremely compromised. We were on a 5 lane highway in the left hand lane going 65. Engine quit and we had to coast to the far right lane in heavy tra]c. We almost got hit several times on the maneuver and rear ended on the side of the road from oncoming vehicles while waiting for a tow. Dealer has work order to repair the vehicle. Vehicle was not inspected by the manufacturer that we know of, nor the police or insurance representatives. Only inspected by the dealership. The Service Department said the parts are on a "Galactic backorder" which means they do not know when they will come in. GM will not repurchase the vehicle or tell me when the vehicle can be repaired. Will not provide any compensation until the issue is resolved, which is unknown and could be months. It is an extreme financial hardship for me to cover my rental car (taxes and insurance for the rental car are not covered) and continue to pay the car payment and the insurance on a car that is not available to me. My case number with GM is [XXX]. GM has sent me to three representatives. Jonathan Phone Number: 1-866-790-5600 Extension: 5927263 (Chevrolet Customer Assistance) Tomorra (866) 790-5600, extension 524688 (supervisor) Janet (866) 790-5600, extension 5910608 (part delay department) None of the reps have given me any assistance with my situation. They just kick me down the chain to someone else that cannot assist me. I simply need my car fixed, loan payed off or a repurchase for the original value of my car so I can purchase another vehicle. Can you direct me to any assistance? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Main bearing failure on my 6.2L at 17,000 miles. Starting making knocking noise, and within two miles it died and wouldn’t restart. No check engine light or warning lights. Blew a 40 amp fuse. Once replaced started but knocked and died. Dealership determined spun main causing internal engine failure. Motor replaced. Started making internal engine noise again like almost a spark knock type noise or rattle under acceleration. Has 32k miles on it now and bring into dealer next week for issue. Engine was on back order and took over a month to get.

Failure - metal in the oil. Engine replacement at roughly 11,800 miles.

They will not repurchase vehicle, will not put in writing why they wont repurchase it. Will not provide any compensation until the issue is resolved, which could be months.

While sitting at an intersection of a busy 4 lane road the engine stoped without warning and could not be restarted. Due to a poor design by GM, the Tahoe has no ability to be put in neutral when the engine isn’t running. We were stuck at a busy intersection an almost hit multiple times, until a tow truck could come since it cannot be put in neutral and pushed. Dealer inspected engine and found it had been burning oil. The car never gave any warning lights that it was low on oil or that there were any engine issues. They did an oil change and gave the car back. The car was running, but within less than 5 miles of driving it it started to shake and make horrible noises. At this point, I was driving on the interstate. I was able to limp the vehicle back to the dealer. It was diagnosed by a dealer with spun engine bearing. I was told they were very close to seizing up and I would’ve been stranded on the interstate with no shoulder. This could’ve caused a major issue as I was on a busy interstate and the vehicle would’ve locked up. There was no shoulder at this point due to construction. Through both of these issues the vehicle never gave any dashboard warning lights. There are two major design flaws. The engine has an issue with its bearings. Also, there needs to be a way to put the vehicle into neutral while the engine is not running. It is not safe to not be able to put these vehicles into neutral.

My vehicle’s engine has been recalled since June. The dealer refused to inspect because there is no remedy to replace the engine. I have complained since I purchased the vehicle of noises that I’ve heard. I am hearing more noises, and I am increasingly getting more scared every day to drive my vehicle. I will not put myself nor my family in harms way I can get into an accident. I am afraid to drive the vehicle. I am not taking any chances of hurting anyone else or my family or potentially have a fatal accident. two months of driving around scared I will not drive my truck anymore. I am beyond upset that there is no remedy for this and that it is not taken seriously. Something needs to be done regarding my situation and all others. The vehicle was sold, most likely knowing that this was a problem. GM needs to make good on this problem before people get killed. I would like them to buy back my vehicle, I am sure I qualify for a full re-purchase. I called GM. They will get back to me in five business days. I cannot emphasize how afraid I am to drive my vehicle and I paid $110,000 for this vehicle.

2023 Tahoe High Country was being operated at Interstate speeds when the vehicle shifted to neutral, engine died and the vehicle experienced a rapid decrease in speed. Check engine light activated as well as dashboard lights. Was able to guide vehicle to side of road. Unable to start vehicle and was towed to local dealership. Learned the engine was blown as well as a large 20amp fuse. I am an expert in traffic crash reconstruction and this type of incident could lead to serious injury or death.

On 5/27/23 I purchased a new 2023 Chevy Tahoe RST with a 6.2L V8 engine. On 5/28/2024, between 5 and 6pm (rush hour) I merged onto State Highway 32 in Maryland. I accelerated to match the speed of traffic and moved to the far-left lane. I was traveling between 60 and 65 MPH when my vehicle shifted into neutral by itself. I was unable to shift the vehicle back into drive. There was no shoulder on the left, so I had to coast through 2 lanes of traffic moving at a similar speed to reach the far-right lane. I could have very easily caused an accident, injuring myself or others. After successfully pulling off onto the shoulder I was still unable to move out of neutral. I had to shut off my engine and restart the vehicle to shift it into drive. I was unable to recreate the failure and safely made it home. In the days following the incident, I began to hear a clicking sound when I accelerated. At no time did a check engine light turn on and my OnStar vehicle report showed my Tahoe was in good health, including the engine. I brought the vehicle to Criswell Chevrolet on 6/14/24 to service the vehicle. I was told later that afternoon that my vehicle required a brand new engine. The vehicle and engine are available for inspection upon request. I was awestruck that a brand new vehicle with 19,000 miles could possibly need to have the engine replaced. While conducting online research, I see that other 2023 Tahoe owners have had a similar experience.

Car completely died. Engine spun a bearing at 10, 000 miles.
