2001 Mitsubishi Diamante mileage at failure

57 of the 78 complaints on file for the 2001 Mitsubishi Diamante give the vehicle's mileage when the problem happened.

Mileage at failure by component, from owners' complaints to NHTSA
Component	Median	Middle half	Based on
Visibility/Wiper	Median 60,000 miles	Middle half 40,000–75,000 miles	Based on 44 complaints

A component's median is its 50th percentile, and its middle half runs from its 25th to its 75th percentile.

Owners give the mileage themselves, often as a round number, and NHTSA doesn't check it. A complaint that names several components counts under each one, and mileages that can't be right, such as 999,999, or 50 miles on a five-year-old car, are left out.

These figures describe the complaints owners filed. They don't predict when a particular vehicle will have a problem, and vehicles that never had one aren't counted.

Incident: January 21, 2011 · Filed: January 21, 2011

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
