Consumer Description

In September of 2022 my gmc automatically shut off right in the middle of traffic on a Friday night. No warring, no lights to indicate that something was wrong with my vehicle. I took it to a mechanic shop and they said nothing was wrong and they did a diagnostic test on the car and no codes popped up. A week later my engine light came on. And my car died again. Thankfully, I had an extended warranty on my car and took to another mechanic shop. It turns out the timing changes on my car needed to be replaced. Fast forward to today Jan 22,2024. I smelled burning oil every time I would drive the vehicle. The rear main seal and PCV was leaking in between my engine and transmission. I lost 5 quarts of oil between Wednesday and Sunday. My oil light never came in. Thankfully, my engine didn’t lock up. It is currently in the shop getting repaired. My car is still under an extended warranty.
