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. they brought it to a body shop they use and fixed the driver's side for $1800. they said the passenger side wasn't a problem to worry about. the dealer is aware of this problem with the qx4 and suggested i complain to their corporate office. corporate wouldn't acknowledge the rotting around welds and said there'd be no compensation because it's out of warranty. i saved the parts. i believe infiniti should pay for the fix of the passenger side and reimburse my $1800. their mechanics and dealers know this is a problem but corporate will risk customers lives for profit.
