2010 Chevrolet Impala fuel system problems

FUEL/PROPULSION SYSTEM

The car can have moments of power loss where the speedometer suddenly, erratically spikes while the tachometer slightly lags. It almost stalled my vehicle while transmission was in drive while stopped. It feels like dragging when the power loss occurs. This has occurred randomly for the past month, mostly during interstate driving with cruise control operating. It has happened the last six times I have driven, but the previous several times it did not occur. It also occurred in a similar random fashion for the prior two weeks. When it does occur it feels like power drain and deceleration that can last a second and this will occur several times during a twenty minute drive at 70mph. Mechanics at two shops seem confused and don't know where to begin except for a transmission fluid flush. That was completed and the problem has persisted. There are no related error codes. To lose power suddenly and unexpectedly could cause an accident especially if a system failure shuts off the vehicle while driving. This vehicle has had an oil consumption/burning problem since I bought it with around 60,000miles. It needed 2 quarts of oil added between the last oil changes. I have spent $1400 in July of this year on gasket replacements and that did not stop the leak. More gasket heads and an oil pan are going to be need to replaced and the estimate is another $1400. This is too much to be spending on possibly related issues in a short time span that may not resolve the problem.

I WAS NOTICED THAT THE CAR IF IT SETS WITHOUT BEING RAN. THAT IT WAS LOSSING GAS ON THE GAS GAUGE. I WOULD PARK THE CAR OVER THE WEEKEND AND WHEN I CHECK THE MONDAY BEFORE WORK THAT THE GAUGE HAD DROPPED. I HAD A FRIEND CHECK AND HE SAID THAT THE FUEL LINES WHERE WET WITH FUEL AND LOOKED LIKE THEY HAD DRAGGED ON THE GROUND. HE SAID I SHOULD GET A HOLD OF A DEALERSHIP TO SEE IF THERE IS A RECALL OR A SAFETY DESIGN FLAW THAT CAN GET THIS FIXED. CAUSE 1 SPARK AND THE CAR COULD CATCH FIRE.

FUEL/PROPULSION SYSTEM

AIR BAG SENSOR HAS BEEN TRIPPED FOR THE PAST 7 MONTHS, I HAVE RESEARCHED THIS RECALL, AND IT LOOKS LIKE THE WIRING HARNESS MIGHT BE THE ONLY THING THAT NEEDS TO BE REPLACED. HOWEVER, WHENEVER, I PUT IN MY VIN NUMBER, THERE AREN'T ANY RECALLS FOR THIS. ALSO, I HAVE RECEIVED A LETTER ABOUT THE GAS SENSOR POSSIBLY BEING BAD, HOWEVER, WHEN I TOOK IT INTO A CHEVY DEALER TO HAVE IT FIXED, THEY REFUSED TO. THEY TOLD ME THAT THE CHECK ENGINE LIGHT WASN'T ON, AND THAT I HAD TO WAIT UNTIL IT FAILED BEFORE THEY WOULD FIX IT! FAILURE OF THIS SENSOR MEANS, IT COULD FAIL IN AN INTERSECTION, OR WHILE I AM PASSING SOMEONE, OR WHATEVER, THIS IS A SAFETY CONCERN!!! I AM VERY UNHAPPY THAT THEY WOULDN'T FIX IT. NOW, MY CHECK ENGINE LIGHT IS ON, HOWEVER, IT IS BECAUSE ANOTHER SENSOR IS BAD! THE EVC SENSOR NOW HAS TO BE FIXED. THE AIRBAG SENSOR WAS TRIPPED WHILE I WAS DRIVING ON THE HWY AT 70 MPH ON A WARM DAY OF 80 F OR SO. THE EVC SENSOR TRIPPED OVERNIGHT WHEN I STARTED THE CAR IN THE MORNING. THE GAS PEDAL SENSOR HAS BEEN A PROBLEM FOR 3 YEARS BECAUSE CHEVY DEALERS REFUSE TO FIX IT. THESE CONCERNS ARE IN ADDITION TO THE OTHER MECHANICAL FIXES THAT I HAVE HAD TO DO ON A CAR THAT HAS LESS THAN 87,000 MILES ON IT! I AM FEELING LIKE I HAVE A LEMON OF A CAR AND THAT THIS IMPALA IS THE WORST CAR ON THE MARKET. I HAVE HAD SEVERAL CHEVY PRODUCTS, AND HAVE NEVER EXPERIENCED PROBLEMS LIKE THIS. WHAT HAPPENED TO THE GREAT PRODUCTS THAT CHEVY ONCE PRODUCED???

FUEL/PROPULSION SYSTEM

REDUCED ENGINE POWER LIGHTS CAME, ON TRACTION CONTROL LIGHT CAME, ON IT WAS HARD TO ACCELERATE IN THE MIDDLE OF A HIGHWAY, CAR ALMOST SHUT DOWN, BUT I MADE IT HOME. IT HAS HAPPENED TWICE ON THE HIGHWAY AND TURNPIKE. I THOUGHT IT WAS OIL BUT THAT WASN'T THE ISSUE. IT STOPS (THE PROBLEMS) AFTER I SHUT THE CAR OFF FOR AN EVENING, BUT I'M SCARED IT WILL POWER DOWN WHILE ON THE HIGHWAY AGAIN. WHEN THIS ISSUE HAPPENS THE CAR BEEPS, THEN THE TRACTION LIGHT COMES ON WITH WARNING AND SO DOES THE ENGINE LIGHT AND REDUCED ENGINE POWER WARNING. ALWAYS IN MOTION, ESPECIALLY HIGHER SPEEDS THAN NORMAL CITY STREETS. SUCH AS TURNPIKE AND HIGHWAY.

AFTER PURCHASING THIS VEHICLE WITHIN 30 DAYS THE AIR BAG SYSTEM LIGHT CAME ON I TOOK THE VEHICLE BACK TO FUTURE NISSAN OF FOLSOM AND THEY STATED THAT I WOULD HAVE TO CALL THE WARRANTY PEOPLE THERE WAS NOTHING THEY COULD DO ABOUT IT. A WEEK LATER I NOTICED WHEN I SLOW DOWN USING THE BREAKS IT MAKES A SHAKING SOUND, MAKING THE WHOLE CAR SHAKE. THIS VEHICLE ALSO HAS NO COVERAGE WHEN PUMPING GAS I NOTICED THE SILVER CAP INSIDE THAT'S SUPPOSE TO REMAIN CLOSED UNTIL YOU PUT THE GAS PUMP IN THERE IN ALWAYS OPEN, WHICH ALLOWS AIR TO GET INSIDE. MY POWERTRAIN IS NOT ACCELERATIONS PROPERLY, IT TAKES ABOUT A MINUTE FOR IT TO CATCH ITS GEAR.

FUEL SYSTEM, GASOLINE

I HAD PURCHASED A 2010 CHEVROLET IMPALA IN JULY, 2010. THE FIRST ATTEMPT AT REPAIR OF THE FRONT END VIBRATION WAS ON 10/22/2010. THE DEALERSHIP DID NOT RECOGNIZE THE VIBRATION. THE VEHICLE TIRES WERE ROTATED ON 01/26/11 IN AN ATTEMPT TO STOP THE VIBRATION IN THE FRONT END. THE VEHICLE WAS TAKEN IN ON 03/18/11 FOR FRONT END NOISE (THUMP) WHILE TURNING THE WHEELS. THE VEHICLE WAS TAKEN IN ON 07/07/11 FOR THE THUMPING NOISE IN THE FRONT END WHILE TURNING THE WHEELS. THE VEHICLE WAS TAKEN IN ON 07/28/11 FOR A FRONT END THUMPING NOISE WHEN TURNING THE WHEELS. THE VEHICLE WAS TAKEN IN ON 08/16/11 FOR A FRONT END THUMPING NOISE AND THE DEALERSHIP NOTICES THE TIRES WERE WEARING SLIGHTLY CUPPED ON THE INSIDE EDGE. THE VEHICLE WAS TAKEN IN ON 09/08/11 FOR A WHINING NOISE FROM THE ENGINE BAY AND POWER STEERING FLUID WAS FLUSHED. THE VEHICLE WAS TAKEN IN ON 04/09/12 FOR FRONT END THUMPING NOISE, WHEEL BEARING, TRANSMISSION SURGE, AND WHINE NOISE FROM RADIO. THE VEHICLE WAS TAKEN IN ON 06/27/12 FOR ROUGH IDLE, TIRE REPLACEMENT, TRANSMISSION. THE VEHICLE WAS TAKEN IN ON 07/27/12 FOR ROUGH IDLE, TRANSMISSION SURGE, THUMP NOISE IN FRONT END AND WHINE NOISE IN RADIO. THE VEHICLE WAS TAKEN IN ON 10/05/12 FOR TRANSMISSION SURGE, ROUGH IDLE, THUMP NOISE IN FRONT END, AND WHINE NOISE IN RADIO. THE OUTCOME AT THIS POINT IS THE DEALERSHIP TRIED TO REPROGRAM THE VEHICLE, GM APPROVED REPLACEMENT OF ALL FOUR TIRES, A REPLACEMENT OF THE POWER STEERING PUMP, WHEEL BEARING ON DRIVER FRONT SIDE. THE DEALERSHIPS HAVE DONE TWO THROTTLE BODY CLEANINGS. THE DEALERSHIP HAS STATED THEY WILL REPLACE THE ROTORS BUT GM WOULD NOT APPROVE REPLACEMENT ONLY TURNING ON THE ROTORS. THIS CASE HAS BEEN OPENED WITH THE BETTER BUSINESS BUREAU WHOM ADVISED ME TO CONTACT NHTSA. GM REFUSES TO REPLACE PARTS BECAUSE THEIR COMPUTER SYSTEM CANNOT TELL THEM WHAT IS WRONG WITH THE VEHICLE. GM HAS RECALLED THE POLICE VEHICLES FOR FRONT END SUSPENSION AND HAS A LAWSUIT PENDING IN MICHIGAN FOR PERSONAL VEHICLE.
