WHILE IN MOTION ONLY, A ENGINE LIGHT ACCOMPANIED BY A REDUCED ENGINE POWER ENGAGES MAKING THE VEHICLE UNMANAGEABLE TO RESPONSE AND CAUSE THE VEHICLE TO STALL.
WHILE DRIVING THE ENVOY AT ABOUT 45 MPH, A WARNING LIGHT SAYING "REDUCED ENGINE POWER" CAME ON SUDDENLY, THE CAR DROPPED DOWN TO ABOUT 20 MPH, AND THAT CONTINUES TO OCCUR. I CAN TURN OFF AND RESTART THE CAR, BUT THE PROBLEM RETURNS WITHIN A MINUTE AFTER DRIVING IT AGAIN. I STARTED INVESTIGATING WHAT THAT MEANS ONLINE, AND, AS WITH ANYTHING ELSE ON THE INTERNET, I SEE MANY OPINIONS, GUESSES, AND POSSIBILITIES. COULD BE A BAD SENSOR, BAD THROTTLE CONTROL, BAD WIRE CONNECTIONS, ETC. BUT THIS MUCH APPEARS CLEAR: (1) IT IS A GM PROBLEM, AND A VERY, VERY COMMON ONE. (2) IT IS A DANGEROUS PROBLEM. THIS SEEMS PRETTY OBVIOUS - THE CAR SUDDENLY LOSES SPEED AND EVIDENTLY SOMETIMES STALLS OUT ALTOGETHER. BUT HEARING ABOUT SO MANY OTHER PEOPLE'S SCARY EXPERIENCES JUST CONFIRMS THIS. (3) IT CAN BE DIFFICULT AND EXPENSIVE TO DIAGNOSE AND FIX. WHEN I THINK OF...
VEHICLE LOSES POWER DRASTICALLY WHEN GOING UP ANY INCLINE. WAS GOING 65 AND SPEED DROPPED TO 35 GOING UP SLIGHT GRADE HILL.
DT*: THE CONTACT STATED WHILE DRIVING VARIOUS SPEEDS, THE 4-WHEEL DRIVE INDICATOR LIGHT ILLUMINATED, AND THE VEHICLE STOPPED AS IF THE BRAKE WAS APPLIED WHEN THE ACCELERATOR PEDAL WAS RELEASED. ALSO, A SMELL WAS COMING FROM THE BRAKES AND THE VEHICLE ACCELERATED WITHOUT WARNING. THE VEHICLE WAS DRIVEN TO THE DEALER WHO DETERMINED THE TRANSFER CASE CONTROL MODULE NEEDED TO BE REPLACED.
WHILE DRIVING VEHICLE SUDDENLY ACCELERATED UNCONTROLLABLY. CONSUMER WAS NOT ABLE TO MAINTAIN CONTROL OF THE VEHICLE, AND IT HIT A GUARD RAIL, FLIPPED OVER SIX TIMES, AND LANDED UPRIGHT. UPON IMPACT, BOTH FRONTAL AIRBAG DID NOT DEPLOY. DRIVER SUSTAINED NECK AND BACK INJURIES AND WAS TRANSPORTED TO THE HOSPITAL. VEHICLE WAS TOTALED OUT BY THE INSURANCE COMPANY. *AK

WHILE AT STOP LIGHT WITH BRAKES APPLIED, VEHICLE SUDDENLY SURGED FORWARD. CONSUMER WAS UNABLE TO STOP VEHICLE, WHEN APPLYING BRAKES STEERING WHEEL LOCKED. IT STOPPED ON ITS OWN, ONCE IT WAS OFF THE ROAD AND ON GRASS. VEHICLE WAS TOWED TO DEALER.*AK *YD

WE PURCHASED NEW VEHICLE OCTOBER 2001 AND WITHIN 4 MONTHS BEGAN EXPERIENCING PROBLEMS BEGINNING WITH A NOISE WITHIN THE STEERING WHEEL. DEALER TECHNICIAN REPLACED DEFECTIVE AIRBAG MODULE. THE NEXT MONTH, MY NEW ENVOY HAS BEEN TO THE DEALER 4 TIMES FOR THE SAME PROBLEM OF 1) WIND AND/OR WHISTLING NOISE AT SPEEDS ABOVE 45MPH, 2) "VIBRATION" NOISE COMING FROM TRANSMISSION WHEN VEHICLE REACHES 3RD GEAR , 3) WHEN VEHICLE HAS REACHED 3RD GEAR AND PREVIOUS NOISE BEGINS, THERE IS ALSO A VIBRATION FELT IN THE ACCELERATION PEDAL. ON THE FIRST TRIP TO DEALER FOR THESE PROBLEMS, TECHNICIAN ONLY AGREED WITH THE WIND NOISE. DISCOVERED THE FRONT SIDE MIRRORS WERE THE CAUSE. REPLACED BOTH MIRRORS---PROBLEM STILL EXISTS, HOWEVER, HE CAN'T HEAR THEM. EXPLAINED IT WAS THE NATURE OF THE VEHICLE. HE ALSO REPAIRED THE WEATHERSTRIPPING WHICH HAD "FALLEN OFF" THE RIGHT REAR DOOR. HE ADVISED THAT HE DID NOT HEAR ANY...
