| In a letter dated august 27, 2008, general motors corp. (gm) notified nhtsa that it will conduct a safety recall (nhtsa recall number 08v-441) to address a safety relateddefect that can result in engine compartment fire in approximately 850,000 vehicles equipped with a heated windshield washer fluid option.the subject vehicles of this investigation comprise over three-quarters of the recall population. according to gm, a short circuit on the printed circuit board for the windshield washer fluid heater module may overheat the control-circuit ground wire. this may cause other electrical features to malfunction, create an odor or cause smoke and in rare cases it may cause a fire.as a remedy, gm dealers will install a wire harness with an in-line fuse. in addition to the subject vehicles, several other gm models with the heated windshield washer fluid option are included in recall 08v-441: my 2006-2008 buick lucerne (manufactured august 2005 through november 2007); my 2008 buick enclave (manufactured february 2007 through april 2007); my 2006-2008 cadillac dts (manufactured may 2007 through november 2007); my 2007-2008 saturn outlook (manufactured august 2006 through april 2007); and my 2007-2008 gmc acadia (manufactured august 2006 through april 2007) vehicles.gm is instructing owners to take their vehicle to a dealer for service if they experience symptoms of windshield washer heater module short circuits. gm's recall resolves the safety defect concerns pursued by this investigation.this engineering analysis is closed. | ||||||

| When vehicle was inspected i was told that there was an exhaust leak in exhaust manifold. dealership found a broken bolt on left side and replaced it. i have just been informed that i now as of 01/30/2012 with 62,760 miles i have another bolt broken on the right side. after researching on internet it is obvious that gm has a design fault in using lower grade bolt which are breaking in large numbers. i implore the ntsa to require gm to replace these defective bolts either by recall or as incident occurs at no cost to car owners. i am told that the exhaust leak can cause failure of the catalytic converter and other engine failure problems which can result in safety issues. *tr | |||

| Vehicle gets extremely low gas, 13 mpg on average. burns oil . need to add 2-3 quarts of oil between oil changes. engine cooling fan stays on for extended periods while driving. all of which the dealership says is normal for the truck. they removed the driveshaft because of clunking at 25k mi. reaction carrier replaced and transmission reconditioned at 36,663 mi after car stopped in the middle of the street. car had to be towed in. at 62k miles engine light on and idles rough. replaced throttle body. at 67k won't engage in reverse and makes klunking sound from reverse to drive. replaced reverse housing, reaction shell, etc. at 75k had a reaction carrier failure, lost power brakes and lost power to the car. almost was rear ended. had to stop in middle of parking lot during christmas rush. waited 5 min and restarted. engine light stayed on, but was able to get to dealership. was told that throttle body needs to be cleaned every 15k miles under service maintence. this was the first time i heard this! not really sure why it had to be cleaned, though, just had the throttle body replaced 13k miles ago. it seems that there are major flaws in the design of the engine. obviously, the dealership has been putting band aids on my problem because they don't know how to fix. i have been very lucky that my family and children have not been in a major accident due to the major flaws in the engine designs. every time i get my car fixed, the tech assures me that they have fixed the problem. i am really afraid to drive this car with so many close calls. the car is a hazard to drive! | |||

| The cooling fan is very loud and stays on for an abnormal amount of time when the car is in park or at a stop while on only when the temperature outside is over 85 degrees. the fan will continue to stay on while driving for 10 to 15 minutes. sometimes it won't shut off until the car is shut off and then restarted. had it for repair on several different occasions at gmc and the technician said that is was normal. *tr | |||
