CHEVROLET SUBURBAN 2023 ENGINE
mediumWhile driving on interstate XXX on 4/17/2026 my vehicle lost power I had to pull over on the shoulder thankfully I was able to do so. Restarted the vehicle for just a short bit and it said loss of engine oil pressure and died. would not restart. Ultimately had to be towed to a GM dealership Lynch Chevrolet in [XXX] . Was told the engine was shot and was covered under the safety recall. There was a recall on the motor I had brought it in to get rectified sept 2025.a heavier weight oil was added and filler cap replaced with 40 weight oil identification. . I just had an oil change the day before the incident on 4/16. What is concerning I'm worried about the long wait plus plus online blogs that indicate the engine failed numerous times even after replacement. I was told from the dealership that the engine was on back order and they cannot give me a time on when it's going to be available. But again I'm worried about this vehicle in general in moving forward or trying to anyway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
