Are previously crashed (but repaired) cars less safe?

Question

Intuinively, even if the car is repaired, the structural integrity of the occupant compartment or the energy absorption of the crumple zones may not be as good as new. Has anyone crash tested previously-crashed cars to compare vs same model new? Or are there statistics on this, such as driver deaths of previously crashed vs similar new vehicles?

Obviously, we're talking here about cars whose previous crashes were not severe enough to total them but were more severe than damage to a fully replaceable, peripheral part, like a bumper or side mirror. I assume there are crashes that fall into this middle-ground (e.g., partially crumpling crumple zones, possibly slightly deforming unibody frame but not enough to total the car).

Or do airbags that have been reset after deployment malfunction more than factory-packed, new airbags?

Answer 1

The short answer - no. If the vehicle has been repaired properly, it is just as structurally sound and as safe as it was prior to the accident. Most critical components designed to fail or crumple during impacts aren't repairable - at least not cost efficiently. Also, anytime an airbag is deployed - it is replaced. They can not be "reset", they are a one time shot deal. In most vehicles, not only is the airbag replaced, but all electrical components relating to the airbag must be replaced as well (ei. the airbag controller). Now, as for the frame repairs; if done properly, following industry accepted standards, the strutural integrity should be unaffected. You'll notice I use the term "should" and "if". The reality is that not all repair shops are created equal, nor the body men. Sub-standard repairs, in an effort to get the job done quickly or cheaply, CAN and do affect possible structural integrity and safety. So the question could be answered either way, depending on how the repairs were performed.

Answer 2

I don't know about any studys to give statistics but I do know that I was rear ended a couple years ago and my car is not the same since... First when I took it in the shops appraiser for the other persons insurance co. said that my vehicle had hail damage to the hoods and top and that I would have to pay nearly $200 of the repairs because of that...I could not see any damage but they swore it was there and I was powerless to do anything to change it.
also and more to the point of this question...the bodyparts just don't line up right... I have a 2002 Honda... the corner point of the trunk and the quarter panels is ...I guess calling it 'pinched' would do... also the front hood does not go all the way down now...It looks like its popped but not unlatched all the time...
and the rear pasenger door has the plastic sealer parts framing the window that keep comming loose...
I was very dissatisfied with the repairs...because this happened when the car was just a year old it had too much value to total but the repairs were I believe in excess of three grand...the frame had to be bent back into 'correct' position...I was told it is just as safe as before but I do NOT believe it...
I hope to trade it in within another year or two...I just hope somebody else doesnt rearend me in that car.

Answer 3

Frame cars ( Crown Vic, GMC Safari, 4Runner, F150) are not affected by this issue

Answer 4

I think that if well restored, they can be close to orginal, but i would still go with a non-wrecked vehicle. Little things may have been bent, twisted, or their strength may be compromised.

Answer 5

they may be safe but they brake down alot sooner and are never the same ie. pulls to the right,sputters,wobbils. hope it helps
