ENGINE AND ENGINE COOLING
BOUGHT CAR 6/2/08 WITH 6000 MILES ON ODOMETER. IMMEDIATELY NOTICED EXTREME VIBRATION THROUGHOUT VEHICLE WHILE DRIVING ALSO IN PARK AT 1500 RPMS. DEALER IN CONSORT WITH GM ATTEMPTED TO FIX; COULD NOT DO IT. DEALER ALLEGES "VEHICLE WORKING AS DESIGNED". APPARENTLY DESIGNED TO VIBRATE. MY CONCERN IS THAT THE PROBLEM IS IN THE ENGINE - NOT IN SUSPENSION OR TIRES, ETC. WITH VIBRATION COMES INORDINATE WEAR AND POSSIBLE FAILURE WHILE DRIVING POSSIBLY CAUSING AN ACCIDENT WITH INJURIES. ADDITIONALLY, THE FRONT SAFETY BELTS ARE DEFECTIVE IN THAT THEY DO NOT LOCK UP AND RESTRAIN THE UPPER TORSO AS DESIGNED. DEALER HAS REPLACED BOTH BELTS; HOWEVER, THEY STILL DO NOT WORK AS DESIGNED AND REQUIRED POSING A CLEAR AND PRESENT DANGER TO THE DRIVER AND PASSENGER IN THE FRONT SEATS. THERE HAS NOT BEEN AN INCIDENT AS YET; HOWEVER, THE POSSIBILITY OF ONE IS RATHER OBVIOUS AND GM THUS FAR HAS BEEN UNABLE TO RESOLVE THE ISSUE SAFELY AND SATISFACTORILY. *TR

SERVICE BRAKES
BRAKES LIGHTS WOULD COME ON BY THEMSELVES WHILE DRIVING OR WHILE PARKED WITHOUT DEPRESSING THE BRAKE PEDAL. ALSO CRUISE CONTROL WOULD BE DISABLED WITHOUT USING THE BRAKE OR ANY SWITCH TO DISABLE IT. TOOK IT TO A GM REPAIR FACILITY (DEALER) WHO RECALIBRATED THE BRAKE PEDAL SWITCH, BUT THE CONDITION RETURNED. TOOK IT TO AN INDEPENDENT REPAIR FACILITY WHO RECALIBRATED THE BRAKE PEDAL SENSOR. THAT INDEPENDENT REPAIR FACILITY THOUGHT THAT THE CRUISE CONTROL PROBLEM WAS RELATED TO THE BRAKE LIGHTS COMING ON BY THEMSELVES. HAZARD: SOMEONE DRIVING BEHIND COULD CONFUSE THE BRAKE LIGHTS COMING ON AS A SIGN THAT THE CAR WAS SUDDENLY STOPPING, WHICH MIGHT CAUSE THE CAR FOLLOWING TO SLAM ON THEIR BRAKES AND CAUSING AN ACCIDENT. *TR
