Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

I HAVE A 2001 MITSUBISHI DIAMANTE, AND AM HAVING PROBLEMS THAT SEEM TO RUN RAMPANT AMONG THIS MODEL/MAKE. MY HEATER CORE WENT OUT AT ABOUT 100K MILES; MY ABS LIGHT STAYS ON (DUE TO A SPEED SENSOR FAIL), WHICH RENDERS THE WHOLE ANTI-LOCK SYSTEM USELESS; AND NOW MY ANTENNA MAST IS BROKEN. ALL OF THESE PROBLEMS ARE PRICEY TO FIX, AND MOST DIAMANTE USERS I HAVE FOUND EXPERIENCE AT LEAST A FEW OF THESE CONFLICTS. ANOTHER PROBLEM I HAVE SEEN MANY COMMENTS ABOUT IS TRANSMISSION FAILURE AT 113K MILES. MY CAR HAS EXACTLY THAT. ON TOP OF EVERYTHING, IT IS WINTER, AND ANTI-LOCK BRAKES ARE MUCH PREFERRED IN ICY WEATHER. I AM STARTING TO SMELL ANTIFREEZE AGAIN, THE WARNING SIGN TO A FAILING HEATER CORE, WHICH CAN LEAK ONTO A TRANSMISSION COMPUTER AND CAUSE IT TO FAIL AS WELL. I AM BEGINNING TO WORRY ABOUT BEING STRANDED, AND EVEN BEING SAFE IN MY CAR. I KNOW I AM NOT THE ONLY ONE COMPLAINING, BECAUSE I HAVE BEEN ONLINE ALL DAY READING FORUMS FROM PEOPLE WITH SIMILAR ISSUES (SEE THE FOLLOWING: HTTP://WWW.CARSURVEY.ORG/REVIEWS/MITSUBISHI/DIAMANTE/R76426/COMMENTS/PAGE-5/). SOMETHING MUST BE DONE! *TR

2001 MITSUBISHI DIAMANTE. WE HAVE HAD IT ABOUT SIX MONTHS. I HAVE HAD IT IN TO A VERY REPUTABLE SERVICE STATION AND HAVE COME UP EMPTY ON THE FOLLOWING PROBLEM. THE CAR HAS NEW TIRES, THIS OCCURRED BEFORE AND AFTER THEY WERE INSTALLED. DURING MORE AGGRESSIVE TURNING THE CAR GETS VERY UNSTABLE, BAD ENOUGH TO LOSE CONTROL. THE SERVICE SHOP CHECKED OUT ALL THE OBVIOUS FRONT END STUFF ALONG WITH THE THREE BUSHINGS ON EACH FRONT WHEEL ASSEMBLY. FOR THE MOST PART THE CAR TRACKS STRAIGHT DOWN THE ROAD AND IS SMOOTH AND TRUE. IT MAY BE DESCRIBED AS A LITTLE SOFT IN HANDLING BUT NOTHING SEVERE UNTIL THIS SITUATION OCCURS. THE SHOCKS AND STRUTS SEEM OK. THE CAR HAS 70,000 MILES? *TR
