“Q-What component or system failed or malfunctioned, and is it available for inspection upon request? A-Suspension and steering effective. Any time I drive and make turns it makes like a clunking noise. You can actually feel it in the floor board. It's worse when you are driving down a not so smooth road. You can look at it as soon as possible. Q-How was your safety or the safety of others put at risk? A-Control arm might SNAP causing you to lose control of my vehicle and crash into other drivers. Q-Has the problem been reproduced or confirmed by a dealer or independent service center? A-Firestone has inspected my car. Q-Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A-No my vehicle has not. Q-Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? A-No warning signs of any kind. This started within the last month or two.”

“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,…”
Power train
91 reports5 crashes
“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.”
