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.

2004 Jeep Wrangler burning alot of oil. Mechanic refuses to repair. The engine used to burn a half a quart of oil between oil changes. That has increased to 1 quart of oil between oil changes. The manufacturer said this was normal and refused to fix the vehicle. The driver's side plastic window cracked.

2004 Jeep Wrangler sport with 4.0 I-6 engine. Would stall after complete warm up while idling in gear. Dealer installed heat shield over fuel injector, but still have stalling problems on cold start. No lights or anything come on. Only had 400 miles on it when first occurred. Now, at 16000 miles, I'm having stalling on cold starts in warm weather only. In the winter, the vehicle runs great. Dealer cannot recreate the problem, and do not know what to do.

Hard starting and stalling. The vehicle will crank and crank and will start sometimes or you must turn the key off and try to restart, and will start the second time, but usually runs poorly for a few seconds. Will sometimes stall when puttin into gear. Dealer has changed fuel pump and put a shield over one of the fuel injectors. Still having the hard starting problem.

While driving 70 mph the engine stalled without warning. As a result the vehicle lost all power. The failures caused the consumer to pull off of the highway without the use of power steering.
