Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

The contact owns a 2001 Nissan Pathfinder. While entering a parking space approximately 5 mph, the contact engaged the brakes and the vehicle unexpectedly accelerated. The vehicle failed to slow down and crashed into an unoccupied vehicle. The ABS warning light illuminated then immediately, the vehicle came to a stop while extensive force was applied to the brake pedal. There were no injuries. A police report was filed. The vehicle was towed to an independent mechanic for diagnostic testing and to be repaired. The vehicle exhibited severe body damage. The contact was in the process of notifying the manufacturer of the defect. The approximate failure mileage was 64,000. Updated 07/08/11

Pathfinder 4WD 6-cyl

  • Automatic transmission
  • 6,500 miles
Fuel/throttle control: I experienced a "sudden unintended acceleration" incident in July of 2002. I was in the process of head in parking and was moving very slowly while applying brakes the vehicle accelerated over curbing into a wall. The vehicle stopped, the engine stopped running, and air bags did not deploy. The vehicle is a 2001 Nissan Pathfinder with less than 8,000 miles on it. I have read of other incidents like this for this vehicle and am now afraid to drive it. No other incident has occured. I have never experience this situation before and I originally thought that I stepped on the acceletator the same time as the brake. Now I believe I did not step on the accelerator but for some reason the vehicle malfunctioned. I have not taken this into the dealer because I have no confidence in their ability to diagnose the problem as it appears to be very intermittent. This is a serious problem that is potentially lethal and cannot be detected by normal maintenance and happens so quickly that the driver cannot react to avoid a serious collision. There were no injuries (this time) but vehicle damage was $500.

problem #1

Feb 242001

Pathfinder 4WD

  • miles
Sudden unintended acceleration (sua) on Feb 24, 2001. After coming to a full stop with transmission in "drive" and remaining stopped for approximately five seconds, the engine speed suddenly went from idle to 5000-6000 RPM. Vehicle remained essentially stationary due to spinning tires on wet pavement and the immediate harder application of brakes, but a collision would have resulted had the pavement been dry. Engine continued to race for approximately five seconds. I set the transmission to "neutral" in reaction to the sua which may have stopped the sua or may have just been coincidental with the sua stopping on its own. I took the vehicle to the Nissan dealer in annapolis, md on Feb 26, 2001; dealer found no stored error codes and could not duplicate the problem. Both Nissan Consumer Affairs and the dealer told me that nothing more could be done until dealer could repeat the sua. Nissan Consumer Affairs has a record of the incident, as does the dealer. This not a case of throttle/brake pedal misapplication. I suspect that the cruise control system is the cause of the sua because I rarely use cruise control when driving this vehicle. I was using cruise control for a prolonged period of time immediately before the incident  approximately 25 miles/20 minutes uninterrupted. Cruise control was most likely set to on when the incident occurred but I did not think to verify this at the time of the incident. Also, and very notably, there have been two separate occasions after the sua incident where the cruise control on light was illuminated when the engine was started (cruise set light was off). The cruise control on light should be off whenever the engine is initially started. I will provide VIN upon request. I donT have the VIN available at this time. Other vehicle particulars: Automatic transmission, SE model.
