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.

2007 Lexus IS 350 Owner Comments

problem #1

IS 350

  • 6,000 miles


The cold idle speed on my car is between 1000 and 1500 rpms. At certain speeds, this causes the car to slowly accelerate with the foot off the accelerator. Every other car I've driven will decelerate with the foot off the accelerator. This causes me to ride the brake at city speeds to maintain a safe speed, with the brake signals potentially confusing to other motorists. Additionally, when navigating snowy or icy parking lots & streets, hitting a slippery patch under the high cold rpms will cause the car to temporarily break free of the breaks, spin the wheels, and lurch forward. The car is equipped with winter tires. This is not a single occurrence, but happens whenever the car is driven while cold.
