STRUCTURE

the dash is cracked around the passenger side airbag. upon checking the internet i found this is a common problem on chevrolet trucks. i am concerned that the structural integrity of the air bag may be compromised in the event of the air bag deployment. it may be possible that pieces of the airbag could break off and strike the occupant in the passenger seat or it may deflect the air bag altogether. chevrolet is not taking the responsibility for fixing this even though it is not a part that would receive wear and tear and it is just an obvious defect in the design.

VISIBILITY/WIPER

vehicle suffers from excessive front/side window fogging in below freezing temperatures and the manual hvac controls will not permit the use of a/c to remove the humidity from the cabin. in summer months or temperatures above freezing, the a/c will engage when the front window defroster is enabled and is effective. with the hvac system in full defrost and no a/c, the fogging actually gets worse and visibility decreases to the point where it is no longer safe to drive and we have had to pull over and wipe the windshield and side glass down. this has happened 6 or so times since acquiring the vehicle new in 2010. an attempt to have the dealer resolve it was not successful.

ELECTRICAL SYSTEM

gm tsb #10047479 this is a well know problem on gm truck and suv models with power adjustable pedals. the wires rub against the mechanism causing a short and making errors to the computer causing communication problems and loss of power. repaired at dealership, and charged $300 for labor no parts involved. not covered because it is a tsb, not a recall. this should be a recall because it could cause an accident from loss of power.

ENGINE

i was driving on a bridge when the check engine light came on and the engine power reduced. the truck immediately dropped to below 30 mph and i could not accelerate up the bridge and barely avoiding an accident, as this was in a heavy traffic area. i was able to get it to the dealership and are working on it now. this if the fifth time this has happened to my truck. my wife and i just sold our 2007 chevrolet tahoe and the only reason was the engine power reduced error occurred on it seven times, three in month prior to selling it. this is a major problem and could have easily resulted in a severe accident. both cars were only ever serviced at chevrolet dealerships and each time, they insisted it was fixed and the problem was gone. we have no faith in chevrolet at this time!

ENGINE

i was on vacation and had my avalanche running while i packed it up to return home. after about 5 minutes of running idle, the check engine light came on and the display showed reduced engine power, service traction control, and service stabilitrak. this had happened to the truck three times before and each time they replaced the accelerator pedal positional sensor. (i also had a 2007 chevrolet tahoe, and after having it repaired seven times for failing sensors and going into reduced engine power while on the highway three times we were forced to sell it). we are very familiar with this issue! however, i was able to locate a dealership in the area and they tested it to find that the throttle body was out, and they replaced the throttle body and the associated sensor. i was relieved to hear that this was a different issue than before and that my problems were fixed. this was not the case. last week, the engine power reduced again and the truck is now in the shop for the fifth time.
