Body & structure
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.

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. …
Tl* the contact owns a 1999 Infiniti QX4. The contact was driving 30 MPH when the ABS warning light illuminated. The vehicle was then taken to the dealer and the contact was advised that there was an extreme separation of the frame, which was severely corroded and causing the warning light to illuminate. The vehicle was not repaired. The failure and current mileage was 95,000.
