2023 CHEVROLET TAHOE Complaints

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.

I went to reverse and my brakes didn’t work, the error then came on dash “break system failure max speed 43 mph” I then had to drift into a parking lot to wait for my car to stop. Car dealership said they can’t find anything wrong, I have images showing the error

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.

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.
