Side mirrors break very easily, and spray a type of antifreeze on the side of the vehicle. This antifreeze stains/corrodes the paint permanently, requiring a paint job. On a minivan, this costs upwards of $1500-2000, as the entire side of the van was splattered. I simply bumped mirrors at a very low speed on a narrow street, the glass shattered, and the antifreeze sprayed the car. The main housing of the mirror was not damaged, illustrating that this was in fact a very minor and small impact. It's bad enough that it caused the glass in the mirror to break, but to cause a $2000 repair is very bad. Dealership reported others have had this issue as well. Cars are judged in part by how expensive they are to repair in a minor collision. This wasn't even a true collision!.

Entire mirror sold as an unit at a exorbitant $485, labor $118 and wait 5 days for part. . When complaining to service people about the mirror breaking they stated it happens quite often in car washes. Old part at home and it looks like it could have been glued back in place with proper glue or broken part replaced for dollars , not close to $600.
