While driving a sensor came on for staiblitraks and no all wheel drive mode was disabled and abs came on. car started to jerk or lunge forward numerous times, until car got up to speed. after i shut the car off and my wife & son who was in a bowling tournement, we came out and started the car and i noticed that when i put the brakes on at first there wasn't any till i started moving.
There is a grinding noise when turning wheels from far left and from far right. generally heard as you begin to back up from a parking space and going forward and turning the steering wheel in either direction. vehicle has about 73,000 miles and new factory recommended tires at 68,000 miles. recently had leaking power steering pump replaced by gm buick garage. gm mechanic can't determined source of grinding sound.
Tires: experiencing tread cracking, loss of tire pressure. i am constantly stopping to add air to tires, loss of pressure is intermittent. car is in motion on city streets, highways and freeways. loss of tire pressure is a great safety concern to me and my family especially when the tire pressure light goes on suddenly and often.
Heated steering wheel gets so hot when initially turned on that it's impossible to hold onto it. i've taken it in to get checked and was told that buick was aware of the problem and that i was to turn the heater off for 10 minutes and restart. the steering wheel does eventually cool off on it's own, but it takes a good couple of minutes and meanwhile, you need to wear a thick glove or do as they suggest and turn it off. doesn't seem to matter if the car is being driven or stationary.
Forward collision alert does not function despite buick dealer's inspection and assurance "it's working properly." traveling over 3,500 miles recently, had two incidents where traffic came to a dead stop or we were cut off and the front end collision alert should have emitted a warning -- we were traveling over 25 mph -- and it did nothing. took to the gm/buick dealer in ft. lauderdale, fl for inspection/service and was told there was nothing wrong with the car, it had "old technology". again, on he drive from florida to michigan, the alert never gave any warnings when traffic came to a sudden stop or we were cut off on the roadway. gm/buick sold us a safety feature that simply does not work and their response is to "buy a newer buick with newer technology." bad business, bad for consumer safety, and false and misleading representation that we have a safety feature that does not appear to work.
When driving on expressway car drops to limp mode i have returned to several dealers no codes can be found. notified gm office about problem. only solution is to give me a 2000 dollar certificate to buy a new gm product. safety problem when you have a 70 year old driving 70 mph in high speed lane and it drops to limp mode.contacted gm central office case [xxx] talked to danielle at 855-880-1400 extension 5914268.. i also have several photo's of the dash board warnings about traction control and stablizer i don't know how to send documents on the computer . it has happen more tha 10 times, i stopped wasting my time for something they can.t find. i believe it's a problem with computer, but they tell me the computer would let them know if its not working correctly. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tt
The lane departure warning does not does not activate until the vehicle is 12" or so into the on-coming traffic lane. this delay could be to late to warn the driver of an impending collision. this happens only when the left side (driver's side) crosses into the other lane. the passenger side works perfectly. this happens on all streets, highways, express ways at 35mph or higher. gm has no way to re-calibrate the system sensitivity.
