“'93 Mitsubishi Diamante. Bought in '98 has smoked after idling at stops for years and I thought it was normal for this make and have found that a lot of Mitsubishi's have the problem also and would like to know the cause. Mechanic's say new engine is needed, but new cars also smoke? Compression is good so what is the underlying problem? Also will not pass deq which is illegal to drive with that much smoke!”

“I am having problems with my braking system. I had my brakes fixed in february 2001, it is now 10/2001 and I have had the brakes replaced again. I am a safe driver and do not drive dangerously or wreckless. I do not understand how wear and tear occured so quickly. My front end vibrates vigorously while breaking. Stopping several feet past the point where I breaked. The brake pedal went all the way to the floor. I have to stop way ahead of a stop. Also, my car shakes and the brake pedal vibrates when I try to stop. …”
