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.

This vehicle allows you to be locked inside. After driving if the driver and passenger open their doors then the lock button is hit on the key (while the doors are still open), then the doors are closed anyone inside in unable to unlock any doors, even when hitting the unlock button inside the vehicle located on the door. This is a huge safety concern.

  • miles
Breach of warranty claims, including but not limited to ignition failure, wiring harness problems, airbag illumination warnings, lock failure, window failure, all within the first 10 months. The vehicle does not go more than 2 or 3 months and 3,000 to 4,000 miles without having these problems come back despite numerous attempts to repair the car. Twice the car would not shut off and a third time the key became locked in the ignition and the ignition would not turn, start, etc. The locks also failed and could not put the car in gear to tow. Became stuck on the road. Manufacturer & dealer can't guarantee the reliability of vehicle but refuses to do anything but continue to temporarily repair car. The car has been in service over 30 days within 10 month period (and counting).
