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.
1999 Infiniti QX4 suspension complaints

Broken strut tower/housing on 1999 qx4. Mechanic just advised it has rusted and torn away on the drivers side. Car is considered unsafe to drive because it is impacting the steering column shaft.
The vehicle is driven exclusively by my wife. She complained to me of a rumbling noise when turning the steering wheel. I investigated. I drove the car up & down our street and confirmed the noise. Whilst someone was turning the wheel back & forth while the vehicle was parked, I followed the noise to its source. I discovered that the left front apron had broken loose from the frame and was making contact with the steering shaft. A further look showed that where the seams of the apron and rails structures were rotted apart where they met. On the engine compartment side of the seam, the break was clean and no rust is evident. On the wheel well side, only paint blistering was evident. When looking the break, there is widespread rot on the rail as well. It seems that the rust was eating up the metal on the inside. It further appears that the fact that the apron hit the steering shaft and was putting pressure on the shaft, the shaft was the only thing that was keeping the strut assembly from ripping apart the rest of the apron assembly and forcing itself into the hood panel. The vehicle was immediately deemed unsafe and has not been driven since. The incident occurred july 16th, 2010. It should be noted that the vehicle has been garaged its whole life, has been repaired and maintained with only genuine infiniti parts and that I had worked for an infiniti dealer for 6 years, and the sole other persons to work on the vehicle besides me are infiniti trained technicians including master certified.
Steering wheel shook. Vehicle has been at dealer 9 times for this problem, could not solve problem. Dealer has done wheel alignment/replaced tires and rack and pinion. But, this did not improve condition. Factory representative stated once rack and pinion was replaced and most consumers were satisfied.*ak
