Traction control system
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,…

THERE ARE HUNDREDS OF POSTS ONLINE ABOUT PEOPLE HAVING THIS PROBLEM OVER AND OVER WITH THIS CAR. IT IS CLEARLY A MANUFACTURERS DEFECT AND CUSTOMERS ARE LEFT PAYING THOUSANDS OF DOLLARS FO THE REPAIR. *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
