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.

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 within a month of purchasing from the infinity dealership. They informed us it was a sensor and then replaced it due to it being within 30 days.

This did not happen every time it was on, but a gamble every time it started. A few months after receiving the car back the problem came back. We constantly had a loner while we dropped it off. It got to the point where they made it seem as if it was our driving, and not the vehicle.

Exhausted we lived with this inconvenience for about 8mnths. At that point the problem was every day. They actually had the lead tech drive the vehicle home for about two weeks so they could diagnose. When diagnosing it. They said it was POSSIBLY a Sensor. By this time roughly after a year had passed and the original replaced sensors warranty was Void even thou it was an ongoing issue.

So now 9then) 07 we out of pocketed for one at 2200$

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
