2008 Chevrolet Impala Powertrain (other) Problems

At a complete stop, press the gas to go and the car will not go. Kind of like its struggling to catch gear and then all of a sudden it with catch jerk hard. That's an issue for a few reasons. If you have to pull out for somewhere that traffic doesn't stop or yield, and the car is barley rolling trying to catch gear, there's the risk of getting hit. When the gear catches, and the jerk happened it's not a small jerk, i feel it's a safety hassard to small children. When my son was 4 months old it started and it jerked him pretty hard. My mother in law is the original owner and had it checked several times with no resolution.

The gas petal sensor is reading a code P2138 (Accelerator Petal Position Sensors 1-2 not plausible). My father has changed the petal not once but twice and erased the code but it keeps coming back. Also getting a p0172 code as well. A Cheverolet dealership has been called and the representative rushed me off phone saying there was not recall for the car. Car was taken to an Autozone and the codes were still coming up. Engine warning light goes off and on every 3 to 4 days after being cleared, then will get a reduced engine power message will appear. Messages warning lights and symptoms started 3 months ago.

WHEN STARTING FROM A STOP, THE CAR WILL SOMETIMES INITIALLY MOVE FORWARD SLOWLY AND THEN SUDDENLY LAUNCH FORWARD ABOUT 3-5 SECONDS AFTER APPLYING THE ACCELERATOR. IT IS ALSO GIVING A TRACTION LOST INDICATOR WHEN I MAKE SHARP TURNS FROM A STOP AND IT SOUNDS AS IF THERE IS SLIPPING FROM THE FRONT END. REMEDY FOR THIS IS TO BACK OFF THE SHARP TURN SLIGHTLY AND ONCE THE CAR IS ROLLING TURN THE WHEEL MORE SHARPLY.

MY CAR STOPPED ON 630. IT SAID DISABLED FULL THROTTLE. I HAD TO SIT FOR 15 MINUTES BEFORE IT WOULD START. I THEN HEAR A CLICKING NOISE THAT STARTED AT 830AM AND STOPPED AT 832AM. I'VE HAD NOTHING BUT PROBLEMS WITH THIS CAR. DO NOT BUY ANY IMPALA, UNLESS YOU HAVE A LIFETIME OF FIXABLE RECALLS. IT'S HOT IN ARKANSAS AND TO STALL FOR 15 MINUTES WITH CHILDREN IN THE CAR IS UNACCEPTABLE. WHEN YOU CALL CHEVY CUSTOMER SERVICE, THEY CAN NOT HELP YOU WITH ANYTHING. THEY JUST TAKE YOUR VIN NUMBER AND STATE OH I DON'T SEE A RECALL FOR YOUR VEHICLE, ALTHOUGH YOU READ 5598 PROBLEMS/SAME ISSUE YOU ARE HAVING WITH YOUR CAR. ERRATIC TRANSMISSION IS THE WHOLE PROBLEM. SO TO CHEVROLET AND COMPANY PLEASE THINK ABOUT FAMILIES AND CHILDREN WHEN ATTEMPTING TO SALE A NEW CAR WITH USED PRODUCTS. IT'S NOT COOL AND THE SAD PART IS YOU WILL NOT FIX IT. WARRANT MY BEHIND CHEVY NEED A LIFETIME OF RECALLS FOR EVERYONE ON ALL CARS. MAY JESUS BE WITH YOUR COMPANY. SINCERELY A MOTHER OF 3 BOYS. *TR

I STARTED SEE A WARNING LIGHT ON IN MY CAR THAT READ "ENGINE POWER IS REDUCED, SERVICE TRACTION CONTROL" SO I SENT GM AN EMAIL REGARDING THIS AND MAYBE A MONTH OR SO LATER I RECEIVED A NOTICE THAT SAID THE GAS THROTTLE SENSOR WILL CAUSE THIS TO APPEAR WHEN IT IS BAD. THEY ADVISED IF I FELT THIS WAS THE PROBLEM I COULD TAKE IT TO A GM DEALER AND HAVE IT CHECK, BUT IF IT WASN'T THEY WOULD NOT COVER IT AND I WOULD BE RESPONSIBLE FOR THE COST OF THE DIAGNOSTICS TEST. I TOOK MY CAR AND TOOK MY CAR , ALONG WITH THE NOTICE TO SUNRISE PONTIAC ON 12/31/15. I WAS TOLD THAT I NEEDED A THERMOSTAT A GAS PRESSURE SENSOR. THE COST TO REPAIR THESE ITEMS WOULD RUN ME ALMOST $900 AND I COULD NOT AFFORD THAT T THIS TIME. I ASKED THE TECHNICIAN, WHICH COULD I GET AWAY WITH NOT FIXING RIGHT NOW AND HE SAID I NEEDED TO GO AHEAD AND REPLACE THE THERMOSTAT TO GET THE CHECK ENGINE LIGHT OFF. I HAD THAT WORK DONE AND THE LIGHT STILL WAS ON, AS WELL AS, THE WARNING LIGHTS. SO I CONTACTED GM AGAIN AND ADVISED THEM OF THE SITUATION. THEY PAID FOR ME TO GO TO SERRA CHEVROLET TO GET ANOTHER DIAGNOSTIC DONE. THIS TIME I WAS TOLD I NEEDED AN APP SENSOR, GAS PRESSURE SENSOR, THERMOSTAT (WHICH HAD ALREADY BEEN REPLACED), AND A TEMPERATURE SENSOR, ALL OF WHICH WOULD RUN ME $1300. I TOLD THEM I COULD NOT AFFORD THAT AND LEFT. I CONTACTED GM ONCE AGAIN AND EXPLAINED WHAT WAS TOLD TO ME AND ASKED WHY THE SENSORS WOULD NOT BE COVERED WHEN THEY WERE APART OF THE GAS THROTTLE BODY? NOW I'M GETTING A WARNING THAT SAYS "STARTING DISABLED SERVICE THROTTLE " AND MY CAR IS LITERALLY CUTTING OFF WHILE I'M DRIVING. I FEEL LIKE THIS IS A MATTER THAT GM SHOULD BE WILLING TO REPAIR FOR THEIR CONSUMERS TO PREVENT ACCIDENT OR DEATH. I 'VE READ ON GOOGLE THAT SEVERAL IMPALA OWNERS ARE EXPERIENCING THE SAME THING. ALSO, WHILE I'M DRIVING MY GEAR CONTROL IS POPPING OUT. THIS IS MY ONLY MEANS OF TRANSPORTATION.
