Electrical Problems Caused by Crushed Harness
I purchased my QX30 two months ago. It was back at the dealership one month after owning it because the backup screen was going black, the audio system was malfunctioning and once after turning the car off and opening the door the radio and lights continued to stay on. I was told it was a software problem and that they updated the system.
Then approximately 6 weeks after owning it I released the rear hatch cover to vacuum only to discover the left harness was crushed. The next day I went to the dealership and asked to have the part replaced. When I went in for my follow-up appointment for another problem I was told the cover itself couldn't be replaced, the entire wiring harness had to be done as well and the dealership wasn't authorized to do that since it was an $11,000 repair. The dealership contacted Infiniti and the request was denied. They said it was designed that way. But when I checked the QX30 loaner they had given me, it wasn't crushed. I then checked a couple other cars on the lot. One was crushed to the point it had actually pushed the VIN number plate up and out of place. Several of the other cars also were also crushed.
I then contacted Infiniti Consumer Affairs. Spoke to a regional manager who told me since I haven't had any problems "yet" with the electrical system they can't and won't do anything about it. She also said while my case has been documented she can't guarantee that if these problems don't occur until after the warranty expires, that Infiniti will be willing to assist me.
The major problem is from what I gather, everything electrical runs through that harness. The regional manager did say that every time the hatch is opened and closed those wires are getting pinched. She also said that even if/when they replace it, it will happen again. If it's crushed once, it's going to get crushed again.
I was told the only way something will be done is if enough people have this problem and complain to consumer affairs. IMHO it is a design flaw that Infiniti won't own up to.
