Problems with 2007 GMC Yukon ENGINE AND ENGINE COOLING

Bought this vehicle in aug 2013. had to bring back to dealer because catalytic converter was no good. had my mechanic check out rest of car and he found excessive rusting on frame especially where rear tire is mounted. *jb

I was driving the vehicle down the road doing 65 mph. the engine light came on and the message appeared that stated "engine power reduced" "service stablitrak" "traction control off". the car lost all power and i was unable to go over 20 mph the rest of my trip home. i went from 65 mph to 20 mph in seconds, on the interstate full of traffic. when i got home i then noticed a "hot" smell. i then had the car towed to a mechanic. *tr

2007 yukon goes into reduced engine power on a regular basis. as a result, there was a crash on one particular incident. on a daily basis, it continues to and the engine cuts out as a result as well, no rhyme or reason. on the interstate, going 70 miles an hour the vehicle cut off, went into reduced engine power and myself and my family were just seconds short from losing our lives. this has all been reported to gm and we've gotten no resolution. motherboards, gas pedals, gas caps, wires, everything you can think of has been replaced on my vehicle and it still goes into reduced engine power putting my families lives at risk. this is an extremely dangerous situation. *kb

Reduced engine power message while driving on the highway at 65mph. my truck immediately dropped down to 35 mph and nearly caused a wreck. *tr

Tl* the contact owns a 2007 gmc yukon. the contact was driving 55 mph when the check engine warning light illuminated and the engine reducing power warning message also illuminated. the vehicle began to lose power and the contact was unable to maneuver the steering wheel. the vehicle was later taken to the dealer for inspection but not repaired. the failure persisted and the contact stated that the vehicle was taken to the dealer three times in regards to the failure but never repaired. the manufacturer was contacted and advised that the auto body assembly be repaired. the vehicle was not repaired. the failure mileage was 76,187 and the current 77,600.

Purchased this vehicle in march 09. it has been in the shop 4 different times for a/c. started about 4 months after purchase. driver side a/c blows hot air, but passenger side and rear work fine. have also experienced the brakes slipping off and on. push the brake pedal and the pedal will drop down a little lower while pressure being applied and vehicle will slide to a halt. happened about 6 times since ownership. chrome plating on interior door handles is peeling, causing cuts/lacerations to hands. recent problem of engine running low of oil in between oil changes. now low about 2 quarts. running oil consumption tests now. *tr

I noticed an approximate 4'' crack on my dash between the windshield and steering wheel hump. i then noticed a similar crack emerging near the top left portion of the front passenger side air bag. i thought maybe the employees where i get my car wash were applying too much pressure. however, after looking online to buy a new dash, i found that i was among many gmc owners that have the same issue. i dont think it is a coincidence that we all have the same cracks, in the same location on the dash. also, the chrome plating on both my driver and front passenger inner door handles is peeling off. i heard that exposure to the sun may be a cause, however, my two front windows have had 5% tint on them since i bought it. also, i just got my vehicle back from the dealership because of check engine light issues. the problem is fixed for now, however, after researching online it seems like there are hundreds of gmc yukon owners experience very similar issues with their vehicle's engine. i keep reading about the "reduced engine power" and "service stabilitrak" warnings. *tr

Tl*the contact owns a 2007 gmc yukon. while parked in the driveway, the vehicle caught fire underneath the hood. the fire spread across the vehicle and caused an explosion, which burned down an entire home. the incident occurred at 5 am. the police and fire departments arrived on the scene and reports were filed. the vin was unknown. the current and failure mileages were approximately 22,000. updated 04-08-08 *bf updated 04/08/08 *tr

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

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 clunking 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 maintenance. 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! *tr
