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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2002 Infiniti QX4 Owner Comments

problem #1

Feb 012011

QX4 V6

  • Automatic transmission
  • 140,000 miles


The vehicle would stall and turn off. It has a delay in Downshifting or does not down shift. Or when coming to any stop the car stalled and we had to turn it back on.

Even when turning the car off to attempt a trouble shoot it seemed not to be going past 2nd gear ....For miles! MILES!! At a time, revving at 4-5RPM this started occurring in 06

Here we are 2011 & 130000miles we have lived with this Worthless sensor for years and it is increasingly worse and worse. Now somewhat new when you adjust the speed on cruise control it now delays and won’t accelerate or decelerate except with one LOUD BANG & a large REV of the RPM... We have stopped driving after the 6th encounter with the speed issue due to lack of control because of the force when it kick in to gear. I have learned allot by my first vehicle purchase & wish I wasn’t so naive and had address the issue more aggressively
