I have small debts in my brand new bumper and my check engine light is on now because they put the wrong grill in it that has a camara, the old one did not have a camera in it. When asked about the light all they did was reset it so the next time I turned the car on it was back on and has been one ever since. When asked what the code said was told older vehicles just do that sometimes and also was told the bumper came in with dents in it. Totally unsatisfied with everything

With everything said would you want them to work on your vehicle?

Why do I have to be the quality inspector? I do not sign papers and pay my bill till I have seen the repair. -Why do you show me a repair that is dirty and I have to wipe it off so I can see the paint that was touch when it was still wet and where there was dirt in the paint. Then where someone tried to buff the dirt out and went down to the plastic. That was just in one place and I was asked to accept that, really? -The supervisors and Managers do not inspect the work before presenting it to the customers? -Why doesn't all the hardware get put back on and get put back on correctly? -When I start asking questions why does the Manager start walking around my vehicle and pointing out issues he said he has found on my vehicle? The problem was with the bumper not the rest of the vehicle. Maybe if he put his time into inspecting the bumper instead I would not have to come back multiple times to do a quality inspection. -Why does the Manager have to lie about things. I was in the shop to see the bumper when it was off and it was being repaired. More than a heat gun was used on it!!!! -And there is more.

I would have given a higher rating but with the way that I have been treated & still don't have the correct door edge film on the car...

Repair Quality

I've hesitated to respond to survey because I'm still waiting for it to be completed - door EDGE FILM. I can tell you that at first I thought it looked great, I saw that there are issues with the paint on rear passenger door. There are 4 distinct spots that they tried to buff but still noticeable. The paint color however seems to be good. I'm hoping that the door edges can be finished soon.

Customer Service

I have waited to complete this survey because as of today, I am still waiting to have been supplied with correct door EDGE film. I've been in 2 times & the last time they were purple & Tim put them on & asked what I thought! The next day (9.10.24) I talked to him & gave him the CORRECT parts # for the door edge film from hondaparts.com. I called this Monday & was told not in & then Wednesday was told he wasn't in but he would call me Thursday (9.19.24). I STILL HAVE NOT REC'D A CALL.
