Defective spindle rods caused premature and excessive tire wear. All four tires are worn bald on the outer edge of each tire. I have always rotated the tires faithfully every 6,000 miles. Purchased the 2008 chev. Impala new. I understand that gm has replaced the defective spindle rods on law enforcement vehs; but gm refuses to fix the problem on public vehs. Under warranty. I am asking the NHTSA for help. Thank you.
When applying the brakes hard going downhill at above 50 mph the steering wheels shimmies from side to side violently. Easing off the brakes reduces the shimmying. This has been a continuous problem and it requires constant awareness when approaching a downhill roadway. Also it occurs whenever a panic stop from greater then 55 mph is attempted. Vehicle is a 2009 roadtrek model 190 popular and weighs close to 9600 lbs. Suspect the disc brakes may be warping under the heat or the abs system is at fault.
