Example complaints

“While driving at 35 MPH on a dry single lane paved road, I unavoidably ran my Infiniti QX4 SUV over a tree branch in the road. The tree branch briefly became entangled under the vehicle and then was expelled. Once the tree branch was released, my ABS light came on. I took my vehicle to my inifiniti dealer who put the vehicle on a lift. Examination showed no damage to the vehicle other than the wiring assembly to the front wheel sensor had its wire and electrical pin pulled from the electrical connector to the front wheel sensor. Abs for the vehicle was disabled.”
NHTSA complaint #10042958, filed 2003-10, 5,900 miles“There is a pulsing feel in the brakes. Have checked online and realized that it seems to be a common enough complaint by other owners. On hard stops the push back by the pedal is hard enough that the brakes lockup intermittently. This is different from the pulsing feel of the anti-lock system. It feels as though the rotors are warped. It is felt in the steering wheel also, and increasingly in the vehicle in normal driving without applying the brakes. It is not the tires which are fastidiously kept new omi. No incident yet but I believe there is a trend that needs to be investigated.”
