So, I took my car for a warrant yesterday and they failed it due to a bent chassis.

I have had the car for 14 years and this has never been seen before.

I have a had 3 "collisions" in the car over the 14 years

• 2x I have been rear ended at slow speed and had cosmetic damage to rear bumper, both fixed by insurance (8Years ago)
• 1x My brakes failed while parked on a steep driveway and the car went slowly through a fence, again fixed by insurance (5 years ago)

What I want to know from someone more intelligent than me is can a chassis get bent with out a collision ie over time

If the only probable cause is a crash, would it be possible to go back to the insurance company and say they didn't fix it right the first time?

Thanks
