NHTSA Complaint #716956 — 1999 JEEP GRAND CHEROKEE

I AM AN OWNER OF A 1999 JEEP GRAND CHEROKEE LIMITED V8. I HAVE ENCOUNTERED MANY PROBLEMS WITH THIS VEHICLE BUT SOME HAVE ALREADY BEEN RESOLVED UNDER MANUFACTURER'S WARRANTY. A COUPLE PROBLEMS STILL EXIST THOUGH. ONE MAIN PROBLEM IS THAT MY VEHICLE OCCASIONALLY STALLS OUT ON ME AT RED LIGHTS. IT IDLES VERY SLOW (@400 RPM) AND THIS IS USUALLY WHEN THE VEHICLE FAILS ON ME. I'LL LOSE POWER TO THE TRANSMISSION, BUT ALL THE ELECTRICAL ITEMS WILL STILL WORK, SUCH AS THE RADIO AND HEATER. WHEN THE ENGINE DIES OUT, THE CHECK ENGINE AND AIRBAG LIGHTS WILL DISPLAY. THIS PROBLEM HAS BEEN BROUGHT TO THE ATTENTION OF TWO DEALERSHIPS BUT HAS NOT YET BEEN RESOLVED. ANOTHER PROBLEM I HAVE IS THAT I WILL FEEL A BIG CLUNK WHEN I AM ACCELERATING, USUALLY WHEN I FIRST START TO DRIVE OFF. THE SECOND TYPE OF CLUNK I FEEL IS WHEN I PUT THE VEHICLE IN REVERSE TO DRIVE. I WILL FEEL A BIG BANG LIKE SOMEBODY HAD HIT ME FROM BEHIND. THIS WILL SPECIFICALLY HAPPEN DURING THE SHIFT FROM REVERSE TO DRIVE. THE THIRD PROBLEM I ENCOUNTER HAPPENS WHEN I HAVE MY HEATER ON. I WILL HAVE THE CONTROL SETTINGS SET @80'S AND THE AIR CONDITIONER WILL OPERATE. I DO NOT HAVE THE SETTING AT DEFROST MODE. IT IS IN REGULAR MODE AND WHEN I WANT THE HEAT, THE AC PLUS THE HEAT WILL TRIGGER. I WOULD GREATLY APPRECIATE IT IF THESE PROBLEMS WERE LOOKED INTO. THANK YOU. *AK
