Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I brought my 1999 Infiniti QX4 to the dealer to determine why the check engine light came on while I was driving. They told me that my strut tower was separated and it needed to go to a body shop. The body shop told me that the problem was that the metal along strut tower welds was rotted, posing a danger of collapse on the steering column. Their check of the passenger side found the same problem, although it's less severe. I have photos and video. They wanted over $6,000 to fix it. Insurance wouldn't cover it so I took it back to Infiniti. …”
