ODI #11569854

Incident: December 29, 2023 · Filed: February 4, 2024

Engine was replaced at 163,000 miles now at 168,000 miles the frame is rusted beyond repair and is about to give at any moment nothing really left near rear axels. This could have definitely caused a horrible accident to myself or others having a big car just give way and collapse. Took it to mechanic who warned me first then next day took it to body shop that said nothing could be done. Basically both said get rid of it for parts as fast as you can and don’t look back. After the body shop guy actually showed me the rusted out areas i was scared to even drive it like the 10miles back to my house. It sucks after spending all that money on an engine and now having this issue and now having to buy a new car.
