NHTSA Complaint #11643815 — 2023 CHEVROLET TAHOE

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.
