I have a 2008 Dodge Avenger. I was in a car accident on January 9th I just got my car from the shop. They did an awesome job on the body work it end up being 5200.00 i paid 500 out of that amount. I let the car sit a few days until i was able to get my plates. Finally got my plates and tried to drive my car on Saturday the engine light came on, oil light came on, and my car is knocking. I took it back to the shop Monday and told them what was going on they said they would look at it and call me back. They called me 45 mins later and said the bottom of my motor is bad and my transmission is bad and it has nothing to do with the accident. Is this possible for this to have nothing at all to do with the accident?
