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.

2003 Acura RSX Owner Comments

problem #2

Jan 282010


  • 86,000 miles


The contact owns a 2003 Acura Rsx with a 4-cylinder, 2.0 liter engine. While driving at speeds of 65 mph, there was a tapping noise coming from under the hood. The vehicle then stalled without warning and shortly after, he was able to restart the vehicle. Once the vehicle was restarted, the vehicle abnormally accelerated and increased in engine rpms of 9,000. He was able to put the vehicle into neutral and maneuver off the highway. The engine then blew itself and made a loud popping noise. He was unable to restart the vehicle at that point. The vehicle was taken to the dealer where they performed a diagnostic and determined the failure to be driver error. The engine was replaced at the owner's expense. The failure and current mileages were approximately 86,000.

I bought my car from a dealer in August 2006, in January of 07 I noticed my 2003 Acura Rsx engine making a ticking sound and the engine revving really high. I took it to my mechanic who said the valves needed replacing as do the camshafts. After many searches online regarding this problem, and finding several other owners experiencing the exact same issue I am shocked Acura has not issued a recall for this.
