Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The upper pulley has squealed for some time now. I took it the dealer where they replaced the belts and blamed the problem on them. This stopped the problem for a short time and has persisted since. I have tried tightening the belt, using belt dressing, and lubrication the pulley. Most times the sound stops, only to return. It occurs mostly when it rains or heavy moisture is in the air. The date of first incident is inaccurate, I am not sure of the first occurrence at this time.”
NHTSA complaint #10018483, filed 2003-05, 10,000 miles“Took car to dmv and it won't pass obd-ii test. I have tried three times. Found out that a TSB-03-13-005 was sent out. Which states how to reset so you can pass the emission test. If you disconnect your battery you computer won't reset till you take it to the dealer who charges you hundreds of dollars to reset a problem that they know about but refuse to correct. So every time I need to go to the dmv I first need to visit the dealer so that he can rip me off, and bypass the emission system. Again they know of the issue they posted the TSB 03-13-005. …”
NHTSA complaint #10141170, filed 2005-10, 78,864 miles“After pulling off from a red light, shifting into second we heard a loud bang (like glass breaking). We pulled off the road. A mechanic happened to be traveling right behind us and stopped. The car had a trail of oil a foot wide and parts strewn all over the road. The mechanic looked under the car and said that it threw a pisten through the engine block and into the transmission. There were parts of the block, pisten, gears...........etc. That we picked-up off the road. I have them in a bag. The car is five years old (just paid for). It has approx 72,000 miles on it. …”
NHTSA complaint #10080649, filed 2004-07, 72,000 miles“While having a basic oil change at the mitsubisihi/chrysler dealership was informed of the head gasket leak. Automotive technician stated that this was a common problem with these motors and a $1000 to repair.”
NHTSA complaint #10187561, filed 2007-04, 35,000 miles“At 58,500 miles head gasket began leaking. Took it to dealer they stated was past 5yr mark from purchase. Mitsubishi is so loyal to their customers not.”
