It appears that after working with Consumer Affairs for many weeks that the final answer is "NO!". "No" to helping me. "No" to admitting they have a problem with their mold.
I was told that the warp is by design. When I asked what would be the reason for that design she said she didn't know. The regional rep visited the dealer and saw that all of the bumpers on the Zs were warped and pronounced it as "Normal".
Well I have news for them. I will NEVER buy another Nissan again. It was my first and now it will be my last. I have never been treated so badly by ANY car company!
