NHTSA Complaint #10164969 — 2002 BUICK RENDEZVOUS

I HAVE BEEN HAVING SO MANY PROBLEMS WITH OUR 2002 BUICK RENDEZVOUS. TOOK IT TO THE SHOP SO MANY TIMES BUT THEY CAN NOT FIND NOR FIX THE PROBLEM. HAD ELECTRICAL PROBLEMS JUST COUPLE OF MONTHS AFTER PURCHASING. RIGHT NOW OF 8/8/06 ITS CURRENTLY IN THE SHOP FOR: 1. ALL EXTERNAL AND INTERNAL LIGHTS INCLUDING HEADLIGHTS AND BACK LIGHTS TURN OFF EVEN WHILE CAR IS IN DRIVE. TURNS OFF FOR ABOUT 6 SECONDS. DROVE COUPLE OF NIGHTS WHEN THIS OCCURRED 1 INCIDENT ON MAJOR HIGHWAY WHILE MERGING, ALMOST AN ACCIDENT. LEFT IN PURE DARKNESS. HAPPENS ANYTIME OF THE DAY. SAFETY ISSUE THAT GM SERVICE HAS NOT YET FIXED. 2. CAR GOES ON LIKE A SECURITY MODE. SERVICE ENGINE LIGHT SOON INDICATOR STAYS ON, RADIO NOT WORK, AC NOT WORK, WINDOWS AND DOORS LOCK, CLOCK STOPS. EVERYTHING ELECTRICAL LOCKS UP. TOOK THIS TO THE SHOP MANY TIMES AND STILL NOT FIXED. BCM CHANGED IN 2004 TO TRY TO FIX THE ELECTRICAL PROBLEMS BUT DID NOT WORK. 3. 1ST TIME ONLY SUV COMPLETELY WON'T START. LAST DRIVEN WAS JULY 31ST 06 AND IT WORKED FINE, IT SAT IN THE GARAGE AFTER. NEXT DAY OF WANTING TO USE IT WAS AUG. 5TH 06 WOULD NOT START AND TRIED TO JUMP CHARGE IT BUT DID NOT WORK. HAD TO GET IT TOWED OUT OF OUR GARAGE. MY VEHICLE IS CURRENTLY BEING DIAGNOSED FOR THE ELECTRICAL PROBLEMS THAT IT HAS BEEN HAVING. SO FAR, NO LUCK ON WHAT'S THE CAUSE OF IT AGAIN. THE INTERNAL AND EXTERNAL LIGHT ISSUE SHOULD REALLY BE ADDRESSED FOR THIS IS SOMETHING TO BE CONCERNED ABOUT. COULD POSSIBLY LEAD TO AN ACCIDENT THEREFORE IT MAY BE TOO LATE. *NM
