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.

Lancer 4-cyl

  • 45,000 miles
First occurrence happened while attempting to leave a convenience store. Clutch went to floor of vehicle, and did not know what was wrong. Since 1st occurrence it has happened regularly approximately every 3-4 weeks. For the last 8 years. Clutch become spongy and requires me to refill master cylinder with brake fluid. Several occasions I have been driving when the occurred. Car loses ability to shift due to clutch not engaging gears. I must be attentive to fluid levels to prevent it from happening. Has been diagnosed as slave cylinder problem.

The clutch cylinder release keeps leaking until it wont clutch. You cant shift gears. Its happenedd 6 times in the last 3 years. The car isn't used for any type of racing because it doesn't even have enough power, just for regular everyday driving. I've talked to the dealership and they said that they will not cover it because it has no warranty anymore but the cars defective and that is their problem. I've been reading and it seems my car is not the only one with this same problem.

Mitsubishi Lancer 2003, defective transmission and brakes. The consumer stated the transmission slipped at every speed and no one would admit there was a problem. The brakes would fade and vibrate making it difficult to stop.

problem #1

  • Automatic transmission
  • 9,500 miles
At around 9500 miles the car began sticking, slipping gears, jamming into gear. It was diagnosed as a failed body valve, which they ordered and sent me home for 10 days waiting for the part--meanwhile the car progressively became worse, making entering the freeway questionable, etc. After 10 days it began doing the same thing--took car back in--they sent me home while they tried to reach Mitsubishi...when I demanded rental stating I did not feel safe (I called Mitsubishi, who intervened and had me take car back to dealer until it is fixed). Dealer told me they are ordering 6 more transmission parts based on Mitsubishi's advice. Meanwhile, I spoke with an independent mechanic who worked for Mitsubishi, who said that if the body valve failed, there is probably internal damage to the transmission and that talking on the phone and ordering parts is not fixing the cause of the problem--also that the transmission and computer have to be in sync, and a damaged transmission could affect the computer of the car. So we have techs talking back and forth on the phone, a dealership service dept that does not have the answers talking to a tech hundreds of miles away, and neither party has seen the inside of the transmission....I feel like I have a defective car and am running to the shop which is just putting bandaids on the problem.
