I WAS DRIVING ON THE FREEWAY AND ALL OF A SUDDEN I HAD 0% OF MY BRAKES AND ALL THE BRAKE FLUID WAS GONE MY EMERGENCY BRAKE ALSO FAILED PRIOR TO THIS I PUT IN BRAKE FLUID AND IT ALL LEAKED OUT WITHIN A MATTER OF MOMENTS
VEHICLE WAS COMING TO A STOP FROM A SPEED OF APPROXIMATELY 30MPH AND BRAKES FAILED SUDDENLY TO BRING VEHICLE TO A STOP A NORMAL RATE. DRIVER NEEDED TO SWERVE OFF ROAD TO AVOID COLLISION. VEHICLE CRASHED INTO SIDE CURVE. NOT WARNING SIGN OR LIGHT WAS LIT BEFORE INCIDENT. CLEAR YELLOWISH FLUID DRAINED FROM UNDERNEATH VEHICLE NEAR DRIVER'S DOOR. *TR
I HAVE 2003 SUBURBAN 1500, THAT KEEPS GETTING A ERROR MESSAGE "REDUCE ENGINE POWER". THE VEHICLE WILL ALL OF SUDDEN WHILE DRIVING, REDUCE SPEED AND I CAN'T ACCELERATE ABOVE 25-30MPH. I WILL HAVE TO PULL OVER AND TURN CAR OFF FOR 10-15 SECONDS BEFORE IT RESETS, HOWEVER IT WILL CONTINUE TO HAPPEN OVER AND OVER AGAIN! IT IS VERY SCARY AND DANGEROUS WHEN I HAVE MY KIDS OR MY WIFE DRIVE IT BECAUSE YOU NEVER KNOW WHEN THE CAR WILL HAVE THIS HAPPEN. STRANGELY, WHEN WE DRIVE ON THE HIGHWAY WE CAN USE THE "CRUISE CONTROL" FEATURE WHEN WE REACH 25MPH AND USE THE CRUISE CONTROL TO ACCELERATE THAT WAY WITH MINIMAL OCCURRENCES. I HAVE TAKEN THE CAR TO "2 CHEVY DEALERS AND 3 MECHANICS" NEITHER CAN TELL US WHAT'S WRONG! THIS IS FRUSTRATING BECAUSE WE ONLY HAVE ON CAR, AND WE KNOW THIS A "SAFETY HAZARD" AND EXTREMELY DANGEROUS AND SOMEBODY HAS TO LOOK INTO THIS! I ONLY HOPE SOMEONE WHO READS THESE COMPLAINTS HAS THE POWER TO HELP ME AND EVERYONE WITH THIS PROBLEM. *TR
ON 26OCT. 2010 I HAD A THROTTLE BODY REPLACE ON A 2003 CHEVY SUBURBAN AT A LOCAL CHEVY DEALERSHIP. A DAY LATER MY WIFE AND I TOOK THE SUBURBAN OUT TO GO SHOPPING . I RETURNED TOTHE PARKING LOT TO PULL UP TO THE DOOR TO LOAD UP. AS I WAS CIIRCLING AROUND IN THE PARKING LOT THE ENGINE OF THE SUV RED LINED ,THIS CAUGHT ME TOTALLY OFF GAURD. I APPLIED THE BRAKES TO THI SUV, IT DID NOT STOPPED . THE END RESULT WAS THAT I HIT A LIGHT POLE IN THE PARKING LOT. I REPORTED THE ACCIDENT TO MY INSURANCE COMPANY. MY IN INSURANCE COMPANY SENT A INVESTIGATOR OUT TO LOOK A THE SUV , HE STARTED THE VEHICLE AND IT REDLINED , HE GAVE ME A CALL AND SAID I HAD A ISSUE WITH THE THROTTLE BODY AND THAT IT COULD HAVE BEEN IMPROPERLY INSTALLED OR IT COULD HAVE BEEN A MANUFACTURE DEFECT. LATER ON I CALLED THE DEALERSHIP THAT INSTALLED AND PROFORMED THE WORK .THEY SAID THAT IT WAS DEFINITELY A DEFECTED AND THAT THEY ARE NOT RESPONSIBILE FOR THE ACCCIDENT. THEY SAID THAT GM WAS RESPONSIBLE FOR THIS ACCIDENT. *TR
TRUCK STALLS OUT WHILE DRIVING. MAY DRIVE FOR 20-30 MILES, THEN STALL OUT. TOOK IT TO THE CHEVRON DEALER, THEY CHECKED, DID NOT FIND ANYTHING WRONG. SAID COMPUTER SHOWS EVERYTHING O.K..

MY 2003 CHEVY SUBURBAN SPEED ODOMETER IS MALFUNCTIONING. WHEN AT A COMPLETE STOP IT READS 30 MPH AND WHEN DRIVING ON THE HIGHWAY IT WILL GO TO 120MPH AND SOMETIMES PAST THAT. VEHICLE JUST HIT 50000 MILES. THIS IS VERY DANGEROUS SAFEY PROBLEM THAT CAN LEAD TO ACCIDENTS AND SPEEDING TICKETS CAUSED BY A KNOWN MALFUNCTION IN GM VEHICLES. THE COST OF REPAIRING THIS PROBLEM IS VERY EXPENSIVE AND SHOULD NOT BE AN OUT OF POCKET EXPENSE.*CN

I HAVE A 2003 CHEVREOLET SUBURBAN THAT HAS A FAULTY, RACING SPEEDOMETER. I JUST SAW A NEWS REPORT ON CBS TELEVISION ABOUT THIS PROBLEM. MY DEALER TOLD ME IT WAS JUST MY CAR. NOW I SEE MANY CARS MAY HAVE THE SAME PROBLEM. THE SPEEDOMETER RANDOMLY RACES TO A VERY HIGH AND INCORRECT SPEED.*JB

SPEEDODOMETER ON MY 2003 CHEVROLET SUBURBAN IS FAILING. I HAVE INQUIRED THE DEALER ABOUT A RECALL, REPAIR, WITHOUT SUCCESS. I HAVE READ THAT THE SPEED ODOMETER HAS BEEN FAILING FOR MANY GM OWNERS BUT GM WILL NOT RECALL THE DEFECTIVE ODOMETER.*AK
SPEEDOMETER QUITS REGISTERING SPEED OF VEHICLE AT TIMES, THE ODOMETER CONTINUES TO WORK. NEXT TIME DRIVING VEHICLE SPEEDOMETER WORKS. DEALER SAID THIS IS A VERY COMMON OCCURRENCE AND EVENTUALLY THE SPEEDOMETER WILL QUIT AND I WILL HAVE TO BUY A NEW ONE. I DO FEEL THAT A NON WORKING SPEEDOMETER IS A SAFETY ISSUE. *JB
DT*: THE CONTACT STATED THE SPEEDOMETER AND TACHOMETER STOPPED WORKING WITHOUT PRIOR WARNING. THE CONTACT TOOK THE VEHICLE TO A DEALER. ALTHOUGH THE DEALER DID NOT INSPECT OR REPAIR THE VEHICLE THE MECHANIC DETERMINED THE SPEEDOMETER CLUSTER GEAR FAILED AND WOULD NEED TO BE REPLACED. *AK UPDATED 01/25/06. *JB
