As I am driving, our vehicle will auto brake, bow up and lose acceleration causing traffic following behind me to either brake or get into the other lane to keep from hitting me. This happens at low levels of speed and at high levels of speed. This will also happen should I be trying to cross traffic as well. I am in fear for the safety of my family and kids as well as the safety of other drivers on the road for they may not be able to get stopped in time. This is a major safety issue which will or could be the cause of 1 or more fatalities.

The contact owns a 2003 Nissan Murano. While driving 25 mph the vehicle suddenly shut off. When the vehicle shut off the brake light began flashing and the brake pedal became difficult engage. The contact was forced to use the emergency brake to stop the vehicle. The dealer informed the contact that the crank sensor needed to be replaced. There is a similar recall on other Nissan models regarding the engine and engine cooling (crank shaft sensor) but the 2003 Murano was not involved in the recall. The contact is concerned about the safety risk since there was no related recall for his year, make and model vehicle. The failure mileage was 90,000.

2003 Murano was stopped. Driver had foot on brake. Vehicle was struck in rear. Brake pedal went to floor and vehicle rolled through intersection. Had to pump brake pedal twice before brakes would hold again. Ever since, vehicle labors as if pulling a heavy load or as if parking brake was partially engaged. Nissan dealer states that brakes seem to work, therefore they will not attempt to find cause of pedal-to-the floor incident or cause of vehicle "laboring".
