 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.

 The a/c fan quit. it smelled like burning plastic. luckily i was able to exit the freeway safely and i have enough electrical knowledge i was able to determine a way to continue safely. it was a fire hazard waiting to happen inside the cab. the resistor was extremely hot and the wiring harness was melted. there were no blown fuses. i pulled fuses to reduce the chance of fire. i have previously attempted to deal with the chevrolet dealer nearest dfw, tx airport and gm over my bad engine block (also reported on this forum) and ........ so i am out the money for this fire hazard too. this is the last gm product i will ever own.

 While listening to the radio, while truck was off, through auxiliary input, the truck suddnly cut off. i lost all power to power steering, power windows, lights, dash would not indicate what gear the truck was in, and of course truck would not start. had to have truck towed to dealership, which they found the bcm had gone out. the dealership found that there was no voltage surge and no reason for the failure. a new bcm was placed in the truck at a 600$ exppense to my self, and the truck is fine now. still worried about why it happened and what caused it so i know it won't happen going down the road, or if i am in an unsafe place.

 This problem pertains to a 2007 chevy silverado. the blower motorshut off while i was driving. i saw smoke come out from under the dashboard by the passenger side. the connector that was attached to the resistor for the blower motor was melting due to extreme heat. the black wire was glowing bright red and was melting the plastic on the connector. after a phone call to the dealership where the truck was purchased, i found out that chevy already new about the problem and that they had seen it many times. the parts to repair it were in stock, they were purchased and replaced. the fan and a/c are now working. this has happened twice and i have to pay each time. this known problem should require gm to pay for the problem.

 My son was driving on the highway in texas when the engine shut down and the car stopped running. he lost all power steering and could barely get off the road in time. the car had to be towed to the nearest town in gainsville. the diagnosis was the sending unit failed and in turn caused damage to the fuel pump that made it inoperable. my concern is that there was no warning light or any kind of indication that this problem was about to occur. there was no way to prevent this. the fuel level read that there should have been 1/4 to 1/2 tank of gas but the mechanic measured 1/8 - 1/4. i'm not sure if the gas level attributed to the shut down or not. that is something that i'm sure will be factored in to your investigation. i feel like this was a definite opportunity for me to speak up and take action. my son was spared from injury or death and there needs to be a solution to this problem to avoid these irreversible consequences. whether it be an indicator light or better yet redesign of the systems so that they cannot shut down the car automatically. remember he was driving 60 miles and hour on an extremely busy highway, the outcome could have easily been very grim, especially had it occurred at night. i may have been planning a funeral instead notifying people how to avoid one. please take this as seriously as i have and take action to eliminate the potential damaging effects of this type of failure. i have documentation of shop records etc. and will be happy to provide any additional information you may need to proceed. thank you for your time. *tr

 I have a 2007 chevy silverado classic that has only 52890 miles on it and the ac went out. my fiance said she noticed an odor of electrical fire or burning when the ac stopped. my kids where in the truck and could have been hurt by smoke inhalation or worse if it would have caught fire. after inspecting the truck i found the blower relay is malfunctioning and the connector is burnt and melted. no fuses or other safety measures prevented this. i looked it up online and there are many cases of people going through this. there are a few websites that sell a new relay and harness that range from only $75 upto $160, but this in not a full harness and cutting and splicing needs to be done. these problems started as far back as the mid 1990's, so why in 07 and beyond has this not been corrected? *tr

 Wires underneath dash of my 2007 silverado crew cab caught on fire on 10/28/08. smoke came pouring out of the dash. called dealer and had them tow vehicle to john megal chevy in dawsonville, ga. tore dash apart only to claim that the installation of an after market brake system caused the fire. would not cover repair under warranty. had to pay $376.95 before they would let us move the truck to the other mechanic that installed the brake system. after mechanic that installed it reviewed the truck, claimed that is should have been covered under warranty. claims brake system was installed correctly. i spoke with 2 more independent trailer dealers and they confirmed it was installed properly. john megel chevy would not cover under warranty even after our research and other professionals confirmed. we had to pay $1300 to have all wiring replaced, $300 in truck rentals, $376.95 to john megel. we are out $2000 for something that gm should have handled. the disrespect we were shown from this dealer is unbelievable. *tr

 Tl*the contact owns a 2007 chevrolet silverado 1500. while driving approximately 30 mph on normal road conditions, the seat belt retractor housing unit exploded unexpectedly. the failure caused a loud popping noise during the explosion. immediately, the driver pulled over into a parking lot to inspect the vehicle. onstar customer service responded with an indication of a front end crash; however, there was no crash and the air bags did not deploy. the air bag warning indicator illuminated on the instrument panel and remained lit until the engine was turned off. the contact took the vehicle to the dealer for diagnostic testing and they stated that the failure was related to corrosion in the wiring system. the parts for the repair were unavailable and the vehicle has not been repaired. the vin and mileages were unknown.

 I bought my 2007 silverado on july 27,2006 i began having electrical problems no more than two weeks later it went in the shop august 08,2006 for windshield wipers malfunctioning the dealer replaced the wiper module a couple months later october 10,2006 wipers were doing the same they again replaced the module and motors ok that's fixed,then my brakes were locking up and would drag when i would stop even at speeds of 5-10 mph and also stay locked after taking off from a stop and also was pulling left then right when brakes were applied they had to change the brake pads and resurface the rotors. march 26, 2007( i had my radio burn up a cd and lights in radio burn out they had to replace the stereo and the back lights on my stereo control buttons and other buttons on steering wheel burnt out they changed those. then my accessory outlet keeps burning out any time i plug anything in it blows a fuse, my speedometer cluster lights burnt out they had to replace that) june 28, 2007 back in the shop for a knocking noise in steering shaft they had to replace the steering shaft. may 05, 2008 steering wheel lights burnt out again they replaced the buttons again. then august 31,2008 my family and i were leaving town due to a mandatory evacuation and i was pulling my trailer when i took the ramp to get off the interstate i had no trouble stopping at the stop sign but when i went to cross into the median at no more than 5-10 mph i had no brakes and was pushed into oncoming traffic which resulted in a crash i bought new tires in july 2008 and you can tell that they are being torn up by the brakes i just got my truck back from the shop and noticed the rear brakes are locking up again and dragging through turns even with no brakes applied at 5-10 mph does this seem like an electrical problem. *tr

 I have a new chevy silverado with 3000 miles on it. when i started it today the nav/radio screen did not come on at first. it remained black. it finally came on and i headed for work. between 5 + 10 miles in the drive the entire electrical system shut down for a instance (everything went black). the engine stayed on but the truck stopped for that instance. i would guess since the trans is electrical was the reason the truck stopped when the electrical went out. this occurred 3-4 times so i headed straight for the dealer. the nav system also went out several times with out the entire electrical going out. it did not occur again on the way to the dealer, possibly since it was warmed up. no check engine lights ever came on. have you seen this before or have a clue what could cause this? the dealer is saying they could not diagnose this intermittent problem. i suggested to leave it overnight and see if they can experience the problem when the truck is cold. they agreed. *tr
