Notes: The 2005 Nissan Altima has two fairly significant problems with the floor pan rusting through & motor mounts breaking.

Altima owners report that up to a basketball-size hole develops under the floor mats where the floor pan metal rusts through. Average repair cost is over $1,000.

The broken motor mounts are less of a problem - they break at ~75,000 miles average & it's $400 to fix. Still, motor mounts should not break!

Altima 4-cyl

  • 91,000 miles


Sorry for my belated complaint. I just learned of your website. Early evening Aug 18, 2016 entire rear window of my 2005 Nissan Altima completely blew out for no apparent reason. Fortunately -- nobody was sitting in back seat(s) of my car - no adults & no children !! what a big mess !! a clear & normal summer evening - no severe weather conditions to even provoke a crazy & sudden incident like this. Luckily -- I was not on a highway. I was on a quiet Suburban road with relatively low traffic. I was at stop light & suddenly heard a loud pop sound -- almost like a gun shot. I checked my rear view mirror & my entire car rear window was blown out with very large holes & tiny shattered glass pieces strewn all over inside back seat area of my car. Some shattered glass even blew out all way to front section where I was seated !! I immediately got off the road & pulled over into nearby walgreens parking lot & called local police. Policeman came & examined my car. He did not feel any foul play was involved nor any gunshot nor baseball thrown into my rear car window. I took 24 photos ? see 5 uploaded. He helped me gather most of broken & shattered glass into a plastic bag. We noted a few pieces had dark brown burn marks on them. He said most likely it indicated a "short" occurred in rear defroster electrical system. He could not prepare police report bcuz it did not involve any foul play. Next day I called Nissan Consumer Affairs (nca). They asked me to email my 24 photos to nca & only agreed to pay to replace rear car window. I told nca it was probably a short in rear defroster electrical system " a serious Nissan safety issue & defect. For me " a scary incident !! I saved all shattered glass pieces with dark brown burn marks, but nca did not want them. Unfortunately -- I can only upload 5 photos. If you want to view all 24 photos - call or text my cell [xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The contact has spoken with Nissan on several occasions and has been without her vehicle for two months. She believes they are giving her the run-around.
