2008 Chevrolet Impala vehicle speed control problems

“IN MOTION ON A CITY STREET TURNING LEFT , PEDAL STUCK BRAKES NOT WORKING AND HIT BY ON COMING CAR , FLIPPED IN AIR ABOUT A BLOCK , ROLLING OVER AGAIN AND AGAIN , NO AIR BAGS DEPLEATED, BROKEN RIBS, CONCUSSION, SKIN LACERATIONS , BRUISES,GLASS LOGGED IN PARTS OF BODY , FACE AND FEET”

“WHEN FIRST PURCHASED I HAD TO CHANGE ACCELERATOR PEDAL. WHEN I TOOK IT TO THE SHOP I WAS TOLD THEY GET A LOT OF PEOPLE W IMPALAS SAME AS MY YEAR 2008 THAT NEEDED TO HAVE THE ACCELERATOR PEDAL CHANGED EVERY SO OFTEN BECAUSE THEY WOULD GO OUT AND IT WOULD CAUSE THE CHECK ENGINE LIGHT TO GO ON AND OFF BECAUSE THE VEHICLE WAS SENDING THE WRONG SIGNALS.I WOULD DRIVE ON THE HIGHWAY AND STREET IT WOULD CAUSE REDUCED ENGINE TO COME ON AND SLOW MY CAR DOWN ALMOST LEADING INTO ACCIDENTS BECAUSE I DID NOT KNOW IT WAS ABOUT TO HAPPEN. IT WOULD COME AND GO ON AS IT WANTED. THE ELECTRICAL PART OF THE CAR IS SOMETHING IN THE CAR CONTINUES TO DRAIN MY BATTERY. I'VE GOTTEN A NEW BATTERY AND IT STILL DRAINS CAUSING ME TO HAVE TO GET IT RECHARGED. THE SUSPENSION I WAS ALSO TOLD FOR THE YEAR OF MY CAR IS BAD. WHEN PURCHASED I FOUND OUT THAT AGAIN PEOPLE THAT PURCHASED THESE YEARS OF VEHICLES HAD PROBLEMS WITH THE CONTROL ARMS AND THAT I NOW HAVE TO TAKE IT TO GET FIXED BECAUSE ONE HIT TO A POT HOLE CAN CAUSE THE UNDER PART OF THE CAR TO BREAK AND CAUSE A BAD ACCIDENT. I DID NOT KNOW IMPALAS HAD THIS MANY PROBLEMS. I SEEN THE POLICE IMPALAS FOR 2008 WERE RECALLED FOR SUSPENSION,…”

“THE STABILITRAK IS MAKING THE CAR SHAKE AND ACT CRAZY. I'M BARELY IN CONTROL OF THE CAR. THERE ARE THOUSANDS OF MORE PEOPLE HAVING THE SAME PROBLEM. THE CAR REDUCES SPEED BECAUSE OF THIS ISSUE. MANY GROUPS AND BLOGS ONLINE ABOUT THIS. WHY HASN'T ANYTHING BEEN DONE ABOUT THIS? NO RECALLS OR ANYTHING.”

“ON INTERSTATE DRIVING APPROX. 60 MPH SUDDENLY CHECK ENGINE LIGHT CAME ON, AND REDUCE ENGINE SPEED LIGHT ON AND CAR DROPPED DRASTICALLY DOWN TO LITERALLY NO POWER. BARELY HAD TIME TO GET ON SHOULDER WITHOUT CAUSING ACCIDENT. WENT TO LOCAL MECHANIC AND HE SAID THAT THE ISSUE WAS THE THROTTLE PEDDLE.”

“WHILE DRIVING ON HIGHWAY MY CAR WILL REDUCE ENGINE SPEED IT WILL DROP FROM 65MPH TO 20MPH SOMETIMES IT SHUTS CLEAR DOWN . I HAVE SO FAR ALMOST BEEN IN TWO COLLISIONS BECAUSE OF THIS.”

“DRIVING ON HIGHWAY @ 60 MPH WHEN ENGINE DIES WITH NO WARNING. DASH SHOWS FOLLOWING MESSAGES: "ENGINE POWER REDUCED" "SERIVCE TRACTION CONTROL" "SERVICE STABILITRAX" POWER STEERING AND POWER BRAKES STOP WORKING. WHEN CAR KEY IS TURNED OFF AND CHECK ENGINE CODES ARE CLEARED, THE CAR STARTS UP FINE AND CONTINUES TO RUN SMOOTHLY. LUCKILY I WAS ABLE TO SAFELY STOP THE CAR (ALBEIT ON THE MIDDLE OF A MAJOR HIGHWAY), TURN IT OFF, CLEAR THE CODES, AND START IT BACK UP TO GET OUT OF THE WAY. SAME PROBLEM HAPPENED IN JANUARY 2018. AFTER THIS I TOOK IT TO A CHEVY DEALER. THEY SAID CAR WAS COVERED UNDER "WARRANTY" FOR THIS PROBLEM AND THEY REPLACED THE THROTTLE BODY. ONE MONTH LATER SAME PROBLEM KEEPS OCCURRING. CAR RUNS FINE BUT THESE MESSAGES APPEAR ABOUT ONCE A MONTH. TYPICALLY THE ENGINE STAYS ON AND IS ONLY LIMITED IN POWER. HOWEVER, OCCASIONALLY THE CAR WILL DIE COMPLETELY WITHOUT WARNING, EVEN ON THE HIGHWAY. HAD CAR BROUGHT TO CHEVY DEALER. THEY SAID THEY CAN NOT FIX THE PROBLEM UNLESS IT IS CURRENTLY OCCURRING WITH THE CAR. THEY RECOMMENDED I TAKE THE CAR AND BRING IT BACK TO THEM WHEN THE PROBLEM HAPPENS AGAIN. HOWEVER, I DO NOT FEEL SAFE DRIVING THIS CAR KNOWING…”
