2009 CHEVROLET IMPALA Vehicle Speed Control Problems

The contact owns a 2009 Chevrolet Impala. The contact stated that after starting the vehicle and shifting to reverse, the check engine warning light illuminated. The contact continued to reverse the vehicle and felt a pulling sensation. The "Traction Control" failure light illuminated. The contact decided to move forward and park the vehicle. After several hours, the contact restarted the vehicle and the check engine warning light remained illuminated. The vehicle was then able to be driven. The failure occurred several times after the tires were changed. The contact linked the failure to NHTSA ID Number: 10090054 (Vehicle Speed Control, Engine). The vehicle was taken to the dealer where it was diagnosed that the accelerator pedal failed and needed to be replaced. The vehicle had been repaired. The vehicle was not returned to the dealer when the failure recurred. The manufacturer was made aware of the failure and it was...

While driving the car it would pop up a message saying “ENGINE POWER REDUCED”. Today while driving it home it popped up with a message saying “STARTING DISABLED, SERVICE THROTTLE” and then the car wouldn’t drive and I had to pull over on the side of the road. For months now when I drive and accelerate at times the car would almost grind. I believe it has to do with the traction control or the transmission.

My car has started slowing down abruptly and displaying Engine Power has been Reduced at random times, but has become more frequent. I have had an independent service center tell me it was the throttle body, so they replaced it. That didn't fix it, so they replaced the accelerator pedal/sensor. It still is happening and when on the interstate, it is so dangerous to slow down with no warning because you can get rear ended quite easily. This first started August 2021 when my wife and I started on a vacation and had to turn around and go home and is still happening, only more frequent. This past Saturday 7/16, I was traveling on Interstate 77 and the engine power kept cutting down about every 10 minutes, so I had to pull over and cut the engine off for a while until it reset. I can't trust it to go...

MY CAR STARTED PUTTING AN EVERYTHING WAS DIM WHILE I WAS DRIVING THE BRAKE LIGHT AN CHECK ENGINE LIGHT BOTH WERE ON

TO WHOM IT MAY CONCERN: I HAVE A 2009 CHEVY IMPALA WITH 100,000 MILES ON IT. THE 1ST TIME THIS ISSUE HAPPENED, I WAS DRIVING SLOWLY, ON A SIDE STREET, IN JULY 2019. OUT OF THE BLUE, THE FOLLOWING WARNINGS APPEARED: ENGINE POWER IS REDUCED, SERVICE STABILITRAK, SERVICE TRACTION CONTROL. IMMEDIATELY MY CAR STARTED RUNNING HORRIBLY (IT DIDN'T WANT TO GO, WAS CHUGGING, AND ALMOST FELT LIKE THE TRANSMISSION WAS SLIPPING). I PARKED IT. LATER I STARTED IT AND ALL WARNINGS WERE GONE, BUT THE ENGINE LIGHT WAS ON. . THE NEXT DAY I STARTED IT AND JUST THE ENGINE LIGHT WAS ON. 3RD DAY I STARTED IT, ENGINE LIGHT STILL ON. DROVE IT TO A SHOP,.RIGHT BEFORE I PULLED IN, THE LIGHT TURNED OFF! THEY SCANNED IT ANYWAY & SAID THAT NOTHING CAME UP. THE CAR HAS DRIVEN JUST FINE, NO WARNINGS OR LIGHTS UNTIL 11/25/2020. I WAS DRIVING...

THIS IS NOT THE FIRST TIME THIS HAS HAPPENED. ON THE HWY GOING 60MPH, ALL OF A SUDDEN MY ENGINE POWER IS REDUCED AND AIRBAG LIGHT CAME ON. THE NEXT DAY THE AIR BAG LIGHT AND ENGINE LIGHT ARE BOTH ON. WENT TO MY MECHANIC FOR AN INSPECTION (WHICH I FAILED DUE TO THE AIRBAG) AND HE INFORMED ME TO CONTACT THE DEALERSHIP FOR RECALL. I DID, ONLY TO FIND OUT THE RECALL IS CLOSED AND I CAN'T GET THIS FIXED UNLESS I COME UP WITH A LOT OF MONEY. I EXPLAINED I NEVER GOT ANYTHING FROM THE MANUFACTURER ABOUT THE RECALL. HOW CAN I GET MY CAR FIXED ON A CLOSED RECALL?

WHILE DRIVING ON ROADS AND INTERSTATES, I FREQUENTLY RECEIVE A DASH NOTIFICATION "ENGINE POWER REDUCED" AND MY SERVICE TRACTION CONTROL AND CHECK ENGINE LIGHT COMES ON. WHEN THIS HAPPENS, MY VEHICLE LOSES SPEED AND CANNOT ACCELERATE ABOVE 40MPH - DANGEROUS, ESPECIALLY ON AN INTERSTATE. THE NOTIFICATION LIGHTS AND SYMPTOMS OCCASIONALLY GO AWAY AFTER TURNING THE ENGINE OFF AND ON, ONLY TO COME BACK LATER. I CANNOT FIND AND ANSWER TO THIS PROBLEM.

LATELY, I HAVE BEEN HAVING ISSUES WITH THE ACCELERATION OF MY VEHICLE. EVERY SO OFTEN, MY ENGINE LIGHT COMES ON AND I GET A "ENGINE REDUCED" NOTIFICATION, AND MY VEHICLE SLOWS DOWN. WHENEVER I REACH 40MPH, MY HP METER DROPS AND MY CAR STARTS SHAKING. THERE HAS EVEN BEEN A TIME WHEN MY CAR WOULD COMPLETELY SHUT OFF AND DISPLAY "IGNITION DISABLED". EACH TIME THIS HAS HAPPENED, THE VEHICLE WAS MOVING ON A HIGHWAY. I WENT TO A SHOP TO GET THE ERROR CODES AND I WILL UPLOAD THEM.

ISSUES WITH THE AIRBAG AND LIGHT THE BLINKERS SHORTED OUT, THE CAR KEPT DYING AND THE KEY GOT STUCK IN THE IGNITION IN A PARKING LOT. THE GEAR SHIFTER WAS GETTING STUCK IN DIFFERENT GEARS BEEN UNDRIVABLE SINCE THE BEGINNING OF AUGUST 2018 DIDN'T KNOW ABOUT THE RECALLS TILL AUGUST BUT THE RECALLS ARE IN 2016 AND 2014

I STARTED MY CAR AND THE CHECK ENGINE LIGHT AND SERVICE TRACTION CONTROL LIGHTS BOTH CAME ON. I GOT ON THE HIGHWAY AND TRIED TO ACCELERATE TO MERGE INTO THE LANE AND MY CAR WOULD NOT ACCELERATE AND THE STEERING WHEEL LOCKED. LUCKILY I WAS ABLE TO GET INTO THE EMERGENCY LANE BEFORE MY CAR SHUT OFF, BUT I WAS VERY CLOSE TO BEING BLASTED BY AN ONCOMING SEMI TRUCK. THIS COULD'VE BEEN FATAL TO ME IF I HAD NOT GOTTEN OVER IN TIME.

"TAKATA RECALL " EVERYTIME I DRIVE MY VEHICLE 5 SECONDS THE CAR JERKS MAKES LOUD SOUND, STARTS BEEPING, MESSAGES APPEAR FLASHING BACK AND FORTH ENGINE POWER REDUCED, SERVICE TRACTION CONTROL, CAR SLOWS DOWN, CAR JERKS AND CHUGS, MAKES LOUD SOUND, BEEPING NOISE FROM MESSAGE BOARD, THROTTLE SOMETHING APPEARS, STEERING WHEEL LOCKS, CAR STOPS, CAN'T STEER CAR OUT OF ROAD, WON'T CRANK, MY CAR SITS IN THE ROAD.

I WAS DRIVING ALONE ON THE HIGHWAY AND NOTICED THAT THE RMP GAUGES WAS GOING UP AND DOWN, THEN SUDDENLY A MESSAGE ON THE DASH READ, SERVICE TRACTION CONTROL, THEN A FEW SECONDS LATER ANOTHER MESSAGE READ, ENGINE POWER REDUCED AND THE CAR WOULD NOT PICK UP ANY SPEED. THIS WAS VERY SCARY AND CONFUSING BECAUSE THE NEXT DAY I HAD NO ISSES BUT HAS NOW IT DID THE SAME THING TODAY. PLEASE HELP.

AS I GO DOWN THE ROAD THE ENGINE LIGHT COMES ON AND THE STABLETREK WARING TRACKION LIGHT ALSO COMES ON LIGHT AND POWER REDUCE ENGINE POWER LIGHT COMES ON BUT NOT ALL THE TIME IT GOES OFF AFTER A DAY OR SO AND THAN NO ONE CAN FINE THE PROBLEM.

WHAT HAS TO HAPPEN BEFORE SOMETHING IS DONE ABOUT THIS PROBLEM ? TRACTION CONTROL LIGHT AND REDUCE ENGINE POWER LIGHT COMES ON GOING DOWN THE INTERSTATE AND THE CAR SHUTS DOWN AND YOU HAVE TO TRY AND GET CAR PULLED OVER TO THE SIDE OF THE ROAD WITHOUT HITTING SOMEONE OR GETTING HIT . THIS IS A VERY COMMON PROBLEM WITH THIS VEHICLE AND NOTHING IS BEING DONE ABOUT IT . I WOULD REALLY LIKE A RESPONSE ON THIS PROBLEM . THIS HAPPENS A LOT SO YOUR DATE YOU WANT INCIDENT HAPPENING IS REALLY NOT RIGHT .

CAR HESITATES ON ACCELERATION FROM A STOP. RPMS GO UP BUT CAR GOES VERY SLOW, LIKE IF IT HAS LOST A LOT OF POWER. ONCE IT STOPS HESITATING IT BANGS INTO GEAR AND SPEEDS FORWARD. IT CAN POSSIBLY CAUSE A CRASH IF DRIVER IS NOT AWARE ITS HESITATING.

I WAS ON THE INTERSTATE, GOING THE SPEED LIMIT. I HAD THE CRUISE CONTROL ON WHEN THE CAR ALERTED ME THAT THE ENGINE POWER REDUCED AND SERVICE TRACTION CONTROL. I CONTINUED TO DRIVE AS THESE MESSAGES HAVE APPEARED ON MY CAR BEFORE. I TRAVELED ANOTHER 40 MILES ALONG THE INTERSTATE AND WAS ABOUT A MILE FROM MY EXIT. I WAS PASSING AN OVER-SIZED TRACTOR TRAILER GOING UP HILL WHEN THE CAR DISPLAYED STARTING DISABLED THROTTLE SERVICE AND THE CAR SHUT OFF. I WAS IN THE LEFT LANE AND HAD TO INITIATE MY EMERGENCY LIGHTS AND WAIT FOR THE TRACTOR TRAILER TO PASS ME SO I COULD MOVE THE CAR OVER TO THE RIGHT SHOULDER. AS THE CAR WAS COMPLETELY SHUTOFF AND WAS JUST COASTING, I HAD TO FIGHT THE STEERING WHEEL TO CONTROL THE CAR. I FEEL LIKE HAD MY SITUATION WAS JUST A LITTLE DIFFERENT, THE CAR COULD HAVE...

INDICATOR LIGHTS FOR REDUCED POWER, SERVICE ENGINE AND TRACTION CONTROL LIGHTS COME ON AT ANYTIME AND GO OFF. EXPERIENCE A LITTLE LACK OF POWER. I WILL DO IT ANY TIME AND ANY CONDITION. IT IS RANDOM. FROM WHAT I HAVE READ I AM WORRIED IF THE CAR WILL LEAVE US STRANDED.

DRIVING DOWN ROAD, ENGINE LIGHT CAME ON, DISPLAYING "REDUCED POWER AND TRACTION CONTROL PROBLEM. TO IT TO CHEVY DEALER IN TOPEKA KS. THEN FOUND OUT THAT THIS HAPPENS A LOT, SOMETIMES CAR SHUTS OFF ALL TOGETHER. MAJOR SAFETY ISSUE, WHY IS THIS NOT A RECALL BY GM. LAW SUIT WAITING TO HAPPEN. CAN I FALL BACK ON GM FOR THE EXPENSE?.

RECEIVING A MESSAGE FOR SERVICE TRACTION CONTROL AND REDUCED ENGINE POWER. THE CHECK ENGINE LIGHT COMES ON. THIS HAS BEEN HAPPENING ON AND OFF FOR WEEKS. THE CAR SLOWS DOWN. NOW THERE IS A TICKING NOISE COMING FROM THE CAR.

I HAVE GOTTEN SERVERAL ERROR WITH CHECK SERVICE TRACTION CONTROL SINCE I PURCHASE THE USE CHEVELOT IMPALA LS 2009 BACK IN 2012. IT ALREADY HAD 88,000 MILES ON IT AND ABOUT A YEAR AFTER I HAD THE CAR I STARTED TO GET THIS MESSAGE. THE SECOND IT OCCURED I WAS ON FREEWAY AND THE ERROR CAME ON AND AFTER I GOT OFF ON THE EXIT MY CAR SHUT DOWN FOR ABOUT 5 MINUTES BEFORE I WAS ABLE TO START IT BACK UP. NOW I HAVE THIS ERROR THIS TIME AND EVERY NOW AND AGAIN IT FEEL LIKE THE CAR WANTS TO JERK EVERY NOW AND AGAIN AND IF I PRESS THE GAS PEDAL DOWN TO QUICKLY THE LIGHT ERROR FLASH WITH THE CAR SIGN SWIRLING MESSAGE ON THE DASHBOARD.

I WAS DRIVING ON THE HIGHWAY WHEN THE SERVICE TRACTION CONTROL CAME UP ON THE DASH ALONG WITH THE TRACTION CONTROL LIGHT, WITH IN SECONDS OF THIS HAPPENING THE CAR READ REDUCED ENGINE POWER. THE CAR IMMEDIATELY LOST POWER AND SLOWED DOWN TO A MAXIMUM OF 25 MPH. THIS SUDDEN LOSS OF POWER CAUSED THE CARS BEHIND ME TO NEARLY MISS REAR-ENDING ME. I HAD TO DRIVE IN THIS CRIPPLED MODE 10 MILES TO REACH THE CLOSEST EXIT. IT IS DUE TO A FAULTY THROTTLE POSITION SENSOR. THIS SEEMS TO BE A VERY COMMON PROBLEM WITH THESE VEHICLES AND CAN CAUSE A SUDDEN LOSS OF POWER.

TRAVELING ON HIGHWAY AT 70 MPH. SERVICE TRACTION, REDUCED ENGINE POWER, SERVICE ENGINE LIGHTS CAME ON, CAR WAS SHAKING, EVERYTHING WAS SHUTTING DOWN. FORTUNATELY IT WAS NOT RUSH HOUR AND I WAS ABLE TO PULL OFF ROAD. I WAS ON A TOLL ROAD THAT AAA CAN NOT RESPOND. I WAITED ABOUT 20 MINUTES AND STARTED THE CAR AND EVERYTHING WAS FINE. TOOK CAR TO OUR MECHANIC, THERE WAS A SERVICE BULLETIN, TO REPLACE THROTTLE BODY ASSEMBLY. SINCE THEN, 2 LETTERS FROM GM ABOUT COVERING COST OF THROTTLE SENSOR, BUT NOT ASSEMBLY. GM IS NOT TAKING CARE OF THE REAL PROBLEM, THE WHOLE ASSEMBLY NEEDS TO BE REPLACED, NOT JUST THE SENSOR! I'VE KEPT THE PART AND INVOICE AND LETTERS FROM GM, THEY SHOULD JUST RECALL BEFORE IT TURNS INTO A CLASS ACTION LAWSUIT!

MY CAR WAS TAKEN INTO THE DEALER TO CHECK ON THE "SERVICE ENGINE SOON" WARNING AND I WAS INFORMED THAT THE COMPUTER SHOWED IT AS AN APPS ISSUE. THEY CHECKED THE APPS AND I WAS INFORMED THAT THEY COULDN'T FIND ANYTHING WRONG AND THAT IT HAD BEEN RESET WITHIN THE COMPUTER SYSTEM AND I WAS GOOD TO GO. TWO MONTHS LATER WHILE TRAVELING AT A SPEED OF 55 MPH ON A HIGHWAY, THE SERVICE ENGINE LIGHT CAME ON, SERVICE STABILITRAK APPEARED ON THE INSTRUMENT PANEL, TRACTION CONTROL OFF LIGHT UP ON THE INSTRUMENT PANEL AND THEN THE RING TONE AND THE "ENGINE POWER IS REDUCED" CAME ON THE INSTRUMENT PANEL. THE NEXT THING I KNEW WAS THAT I HAD ABSOLUTELY NO ACCELERATION AT ALL! I WAS EXTREMELY FORTUNATE THAT THE VEHICLES BEHIND ME WERE FAR ENOUGH BEHIND ME AND I WAS ABLE TO GET OFF OF THE ROAD AND ON...

MY NAME IS [XXX] AND I PURCHASED A 2009 CHEVY IMPALA, WITH 123,000 MILES ON IT, IN AUGUST 2015 FROM MAC CHURCHILL AUTO MALL IN BEDFORD, TEXAS. I HAVE HAD NO PROBLEMS WITH THIS CAR SINCE ITS PURCHASE UNTIL NOVEMBER 29TH. WHILE EN ROUTE TO EMORY, TEXAS, MY CAR STARTED DISPLAYING "ENGINE POWER IS REDUCED" AND "SERVICE TRACTION CONTROL" MESSAGES. ABOUT 99% OF THE WAY THERE, I SUDDENLY GOT A LURCH AND MY CAR SLOWED DOWN, WITH STEERING AND BRAKING NOT WORKING. I WAS ABLE TO GET MY CAR OFF THE HIGHWAY SAFELY BUT HAD TO USE MY EMERGENCY BRAKE TO STOP MY VEHICLE AND GET IT TURNED OFF. I TRIED REPEATEDLY FOR SEVERAL MINUTES TO GET IT GOING AGAIN, BUT IT WOULD NOT START. AFTER ABOUT FIVE MINUTES, THE CAR RESTARTED NORMALLY AND HAS PERFORMED FLAWLESSLY SINCE. HOWEVER, I AM CONCERNED. I'VE HAD A GARAGE PULL AND DIAGNOSE THE...

2009 CHEVROLET IMPALA. CONSUMER WRITES IN REGARDS TO CONNECTION WITHIN THE ACCELERATOR PEDAL POSITION SENSOR MAY REDUCED ENGINE POWER AND CAUSE LOSS OF TRACTION CONTROL ASSIST. *SMD

FOR A FEW YEARS I'VE HAD PROBLEMS WITH THE ACCELERATOR PEDAL. THE FIRST TIME WAS ROUGHLY TWO YEARS AGO WHEN THE CAR COMPLETELY LOCKED UP AND SHUT DOWN ON THE HIGHWAY JUST BEFORE RUSH HOUR. I RECEIVED AN ERROR CODE TO CHECK TRACTION CONTROL AND THAT THE ENGINE POWER IS BEING REDUCED. THE CAR THEN LOOSES SPEED DROPPING DRASTICALLY. THE FIRST TIME I WAS IN THE FAST LANE ON THE HIGHWAY AND THE VEHICLES COMPUTER SYSTEM SHUT DOWN. THE STEERING WHEEL LOCKED MAKING IT VERY DIFFICULT TO VEER OFF TO THE SIDE OF THE HIGH WAY. LUCKILY NO OTHER VEHICLES WERE DIRECTLY BEHIND ME, AND I WAS ABLE TO GET THE CAR TO THE SIDE OF THE HIGHWAY ACCIDENT FREE. I'VE NEVER BEEN SO AFRAID AND TERRIFIED IN MY LIFE. I FEAR THIS ISSUE WILL CAUSE FATALITIES THAT CAN BE PREVENTED. I HAD THE CAR SERVICED AT A CHEVROLET DEALERSHIP...

WAS DRIVING ALONG AT 55MPH AND THE SERVICE TRACTION SYSTEM LIGHT CAME ON FOLLOWED BY THE REDUCED ENGINE POWER LIGHT. THEN THE CAR JUST COMPLETLY DIED. I WAS ABLE TO GET TO RIGHT SHOULDER AND PARK IT. I HAVE DONE SOME RESEARCH AND SEEMS THAT THERE HAVE BEEN SEVERAL OTHER FOLKS WITH THE SAME ISSUE. I CAN'T BELIEVE THAT THIS CAR WOULD JUST SHUT DOWN AND HAVE NO CONTROL. I HAD THE ENTIRE FAMILY IN THE CAR AND WAS THANKFUL THAT THIS DIDN'T CAUSE AN ACCIDENT. I AM LOOKING FOR ANSWERS AND PLAN ON TAKING IT TO THE CHEVY DEALERSHIP I PURCHASED THE CAR FROM TODAY OR TOMORROW.

WHILE DRIVING, THERE IS A SUDDEN LOSS OF POWER. ENGINE AND TRACTION CONTROL LIGHTS COME ON. DRY PAVEMENT WITH NOTHING ON SURFACE TO LOSE TRACTION. HAVE TO COAST TO SIDE OF ROAD TO AVOID BEING STRUCK BY OTHER VEHICLES.

MY WIFE AND I WERE DRIVING DOWN THE INTERSTATE AT APPROXIMATELY 65 MPH. A LIGHT ON THE DASH CAME ON SAYING ENGINE POWER REDUCED. AT THAT POINT MY VEHICLE SLOWED DOWN TO NEARLY 20 MPH WHILE I WAS STILL ON THE INTERSTATE IN MODERATE TRAFFIC. I PULLED OFF TO THE SIDE OF THE ROAD AND TURNED MY VEHICLE OFF TO TRY TO INVESTIGATE THE PROBLEM. AT THAT POINT MY VEHICLE WOULD NOT START FOR ABOUT 10 MINUTES. AFTER GETTING MY VEHICLE TO START I IMMEDIATELY DROVE IT HOME. THIS ISSUE COULD HAVE CAUSED A VERY SERIOUS ACCIDENT THAT WOULD HAVE INJURED MY WIFE AND I, BUT MORE IMPORTANTLY OUR 7 YEAR OLD DAUGHTER RIDING IN THE BACK SEAT ALONG WITH ANY ONE ELSE INVOLVED. I HAVE BEEN ON MANY DIFFERENT FORUMS TRYING TO FIGURE OUT THE CAUSE OF THE PROBLEM, AND IT SEEMS THERE ARE MANY PEOPLE WITH THIS EXACT...

ON JULY 24TH, MY CAR EXPERIENCE THESE SAME MESSAGES ONCE AGAIN. HOWEVER, THE MESSAGE CAME AND WENT MULTIPLE TIMES AND ALL SPEEDS IN TOWN AND ON THE HIGHWAY. THE MESSAGE FINALLY STAYED AND DID NOT GO AWAY ON JULY 25TH. I SCHEDULED SERVICE AT THE LOCAL DEALER ON THURSDAY, JULY 30. THEY CHANGED THE ACCELERATOR PEDAL AND THOUGHT IT WAS AN ISSUE THAT GM ISSUED A SPECIAL CONDITION ON IN APRIL 2015. ON THE WAY HOME FROM THE SHOP, THE MESSAGE APPEARED AGAIN. THUS, THE CAR WAS AGAIN SERVICED AT THE LOCAL DEALERSHIP ON FRIDAY, JULY 31. BY AUGUST 1, THE...

REDUCED ENGINE POWER, CAR CUTS OFF WHILE DRIVING. CHEVY IS AWARE OF DEFECT AND REFUSES TO RECALL

I WAS DRIVING ON THE HIGHWAY AND ALL OF THE SUDDEN CHECK ENGINE LIGHT AND TRACTION CONTROL LIGHT COME ON. WARNINGS SERVICE TRACTION CONTROL AND REDUCED ENGINE POWER ARE DISPLAYED AND ALL BUT SHUTS MY CAR OFF IN THE MIDDLE OF THE HIGHWAY CAUSING CARS TO SLAM ON THEIR BRAKES AND SWERVE BARELY MISSING ME.

CAR STRUGGLES THEN KICKS INTO GEAR. GOT WARNING ABOUT TRACTION CONTROL FAILING THEN THE CAR SAYS 'ENGINE POWER REDUCED' AND SPEED CUTS IN HALF. *TR

THE TRACTION CONTROL, STABILITY TRACK AND ABS LIGHTS ALL CAME ON. THE ENGINE POWER REDUCED LIGHT CAME ON AND ENGINE POWER WAS LOWER. I HAD THE LEFT SPEED SENSOR REPLACED AND THE ACCELERATOR SENSOR REPLACE ON AUGUST 8TH AFTER THE DEALERSHIP HAD FIXED THIS PROBLEM IN APRIL AND AGAIN IN JUNE. I WAS TOLD THEY CHANGED SENSORS THEN ALSO, BUT I AM NOT SURE OF WHICH ONES AT THAT TIME. I AM NOW HAVING THE SAME PROBLEM FOR THE FORTH TIME. REPLACING THE SENSORS EVERY FEW MONTHS IS GETTING EXPENSIVE. ALSO NOT VERY SAFE. I CONTACTED GM AND THE WOMAN TOLD ME TO TAKE IT BACK TO THE DEALERSHIP TO BE FIXED AGAIN. I HAVE FIXED THE SAME ISSUE THREE TIMES ALREADY. THEY WERE OF NO HELP AT ALL. *TR
