DRIVING THE IMPALA SS ON WINTER ROADS IN INDIANA HAS BECOME A CHALLENGE WITH THIS CAR. ANY ICE OR SNOW ON THE ROAD WILL ONLY ALLOW YOU TO DRIVE 45 MPH AT THE MAX AND THEN THE REAR OF THE CAR STARTS TO SWERVE BACK AND FORTH AS IF THE TIRES ARE FIGHTING ONE AND ANOTHER FOR CONTROL. CONTACTED THE LOCAL CHEVY DEALER AND WAS TOLD BY THE SERVICE DEPARTMENT THAT IT IS A TIRE PROBLEM WITH THE GOOD YEAR EAGLE RS-A P235/50 R 18 AND THEY HAVE HAD A LOT OF COMPLAINTS ON NO TRACTION WITH THESE TIRES. SERVICE REP STATED THE TIRES NEEDED TO BE TAKEN OFF AND NEW TIRES PUT ON. NOT COVERED BY THE WARRANTY. CALLED GOOD YEAR CUSTOMER SERVICE TOLD THEM THE PROBLEM AND THEY SCHEDULE AN APPOINTMENT FOR ME. TOOK IT TO THE AUTHORIZED GOOD YEAR DEALER AND THEY CALLED BACK AND SAID THE TIRES HAVE HALF THEIR TREAD LEFT AND NO PROBLEMS WITH THE TIRES. HE STATED THAT THE TIRE IS TO WIDE FOR DRIVING IN THE WINTER TIME AND BASICALLY FLOATS ON THE ICE AND SNOW AND WOULD SUGGEST ONLY DIVING THE CAR IN THE SUMMER MONTHS. SO HERE IS THE DILEMMA, THE MANUFACTURE KNOWS THAT THEY HAVE HAD A LOT OF COMPLAINTS WITH THE TIRES (WHICH ARE THE ORIGINAL TIRES THAT ARE SOLD WITH THE CAR. THE TIRE MANUFACTURE STATES THE TIRE IS TO WIDE FOR DRIVING ON SNOW OR ICE AND I NEED TO PARK IT INTO SUMMER GETS HERE AND IF SO IF I DRIVE THE CAR IN THE WINTER, I HAVE BEEN WARNED THAT IT IS TOO DANGEROUS TO DRIVE.

I PURCHASED MY 2008 IMPALA WITH 28K MILES IN MARCH 2009-CERTIFIED USED. I HAD TO REPLACE THE TIRES WITHIN THE FIRST 6 MONTHS OF OWNERSHIP ( I WAS TOLD THAT GM USES CHEAP TIRES. FROM THE OUTSIDE THE TREAD WAS FINE AND IT APPEARED TO BE IN GOOD SHAPE BUT WHEN IT WAS ON THE LIFT THE TOLD ME THEY ALL HAD METAL SHOWING. I PAID THIS CAR OFF AND GAVE IT TO MY SON IN APRIL 2010- HE HAS SINCE CHANGED ALL 4 TIRES BACK TIRES 3 TIMES. WE HAD THEM ROTATED AND ALIGNED TWICE, THAT IS WHEN IT WAS DISCOVERED THAT THE TIRES HAD WORN ON THE INSIDE AGAIN. THERE IS NO WAY TO KNOW UNLESS IT IS ON A LIFT. MY SON TOOK THE IMPALA TO THE DEALER SERVICE YESTERDAY AND PURCHASED HIS 2 TIRES- IT WAS AGREED BY SERVICE MANAGER THAT IF WE TOOK THE CAR THERE AND BOUGHT TIRES FROM UNIVERSAL THAT HE WOULD PUT THEM ON, DO AN ALIGNMENT AND MOST IMPORTANT INSTALL THE CAMBER BOLT KIT AT NO EXTRA CHARGE. THIS WAS ALSO TOLD TO CHEVY BY (THE SERVICE MANAGER) WHEN THEY CALLED HIM. I DIDN'T GO WITH MY SON TO PICK UP THE CAR- I DID HOWEVER PAY THE $350 WHICH WAS THE PRICE AGREED IMAGINE MY COMPLETE ANGER WHEN I FOUND OUT LAST NIGHT THE CAMBER BOLT KIT WAS NOT INSTALLED AND ALL THAT WAS DONE 2 NEW TIRES AND AN ALIGNMENT! I COULD HAVE DONE THAT DOWN THE STREET FOR LESS MONEY. I EXPECT GM TO DO A RECALL AND FIX THIS SUSPENSION ISSUES- WE HAVE REPLACED TIRES 3 TIMES IN THE LAST 6 MONTHS AND ALIGNED 2 TIMES. WHAT KIND OF NONSENSE IS IT TO TELL MY SON HE DOESN'T NEED THE KIT? AFTER SO MANY COMPLAINTS OF THE SAME ISSUE\GM ISSUED A TSB #08032 FOR POLICE IMPALAS THAT ARE ON THE SAME PLATFORM AND SUSPENSION, BUT NEVER EXTENDED THAT TO THE PUBLIC. SEEMS TO ME THAT THE REAR SUSPENSION HAS AN SEVERE DEFECT THAT CAN CAUSE TIRE BLOWOUT WITHOUT WARNING. NO TIRES SHOULD WEAR LIKE THAT WITH LESS THAN 17,000 MILES WITHOUT A REAR SUSPENSION AND ALIGNMENT PROBLEM THAT NEEDS TO BE RECALLED FOR REPAIR AND REPLACEMENT OF THE PARTS AND TIRES. DOES SOMEONE HAVE TO DIE DUE A DEFECT ON THE CAR ITSELF? THIS HAS TO BE FIXED FOR EVERYONE. *TR

WE PURCHASED THE CAR AS A DEMO MODEL IN 2009 AND WERE NOT MADE AWARE OF THE PROBLEM. WE BELIEVE THE DEALER WAS HONEST, AND ALSO NOT AWARE OF THE PROBLEM AT THE TIME. WE BELIEVE THIS TO BE A SAFETY ISSUE AS WELL, SINCE HANDLING ON WET ROADS IS EFFECTED DUE TO THE FACT THE REAR TIRES ARE CONTACTING THE ROAD SURFACE ONLY ON 1-2" OF THE INSIDE SURFACE OF THE TIRES. *TR

WHICH MY CAR ALSO FALLS IN THIS RANGE. THEY HAD DEFECTIVE SPINDLE RODS IN THEM, HOWEVER AS A CONSUMER AND NOT A "POLICE" VEHICLE GM TELLS ME I AM RESPONSIBLE FOR HAVING THE PROPER WORK DONE TO HAVE MY CAR FIXED. UPON SEARCHING MYSELF I HAVE FOUND NUMEROUS "CONSUMER" COMPLAINTS REGARDING PREMATURE TIRE WEAR ON THESE VEHICLES. I SEE THIS AS A CONSIDERABLE SAFETY CONCERN THAT THE MANUFACTURER SHOULD BE HELD ACCOUNTABLE FOR REGARDLESS OF WHETHER IT IS A CIVILIAN OR POLICE VEHICLE. *TR

14V355000 · Electrical System:ignition

Jun 23, 2014

This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.

Consequence & remedy

Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.

Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.

12V377000 · Suspension:front:control Arm:lower Arm

Aug 3, 2012

General Motors (GM) is recalling certain model year 2008-2012 Chevrolet Impala police vehicles because the front lower control arms may fracture. This safety recall does not include non-police Chevrolet Impala vehicles.

Consequence & remedy

Consequence: A broken control arm can result in the loss of control of the vehicle, increasing the risk of a crash.

Remedy: GM will notify owners, and dealers will replace both front lower control arms, free of charge. The safety recall began on August 21, 2012. Owners may contact the Chevrolet owner center at 1-866-694-6546.

Opened Jul 22, 2014 · Closed Mar 7, 2017

Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal:sensor/control MODULE-INACTIVE

The Agency received a petition on November 14, 2013 requesting an investigation into the operation of the passenger air bag Occupant Classification System (OCS) software logic and algorithm.The petitioner states that due to this alleged defect, the passenger air bag may be suppressed at point of impact and not provided the occupant protection as needed in a crash.On July 22, 2014, NHTSA opened DP14-001 to further review the crash event and perform a more comprehensive search and analysis of the Fatality Analysis Reporting System (FARS).The Agency also collected manufacturers reports on the alleged OCS issue on the subject Impala vehicles and other GM and non-GM peer vehicles.After examination of the petition and available data relating to the subject vehicle's OCS and the specific crash incident where the OCS allegedly failed to operate properly, NHTSA did not identify an issue with the MY2008 Impala involved in the subject crash, nor has it identified a safety-related defect trend existing in the OCS used in the MY 2006-2008 Impala vehicles, in GM peer vehicles or in other non-GM peer vehicles.NHTSA has concluded that further expenditure of the agency's investigative resources is not warranted. The agency accordingly has denied the petition.However, the agency will take further action if warranted by changing future circumstances. The official petition denial, as published in the Federal Register, is available in the document file for this defect petition.The single complaint and crash noted in the Failure Report above is the petitioner's VOQ (10568388) and can be reviewed online at https://www.nhtsa.gov/recalls?nhtsaId=10568388.
