Recently reported ENGINE problems on 2009 GMC Acadia

In 2 years of ownership i have replaced 4 ignition coils and the vehicle now needs yet another. at roughly 85000 miles (and year 5) the transmission wave plate failed. gm would only authorize a rebuild (last week). *tr

Driving down the road and notice a deer. speed limit was 55, so we had slowed down to about 45. deer crossing in front of us, and we almost come to a complete stop (about 10-15mph). we hit the deer on the passenger front. get out of the car to assess the damage, and notice a fire under the grill and headlights. air bags had deployed. everyone evacuated the vehicle, and it was a total loss. *tr

I took my 2009 acadia into the gmc dealer with around 65,000 miles on it after buying it used (1 previous owner) with around 42,000 miles. they told me i had a power steering leak in the rack and pinion and it would cost around $2000 to replace a seal because they have to pull the whole rack off. he told me it would be okay for a while, but eventually it would cause the power steering to go out. after researching, i've seen multiple other acadia owners who have had the exact same problem. i have refused to pay for the repairs because i think this is a safety issue that has effected enough of this model vehicle to warrant a general safety recall. i know of 3 other people in my hometown who have experienced power steering problems with their acadia's, and the gmc dealership acknowledged to me that it is a significant problem with gmc acadia model years 2008-2012. if that's not enough, then i'm not sure what is, but if my power steering goes out while i'm driving, well, let this serve as notice to gmc. *tr

Bought used 2009 acadia in 2011 with 55000 miles and nothing but headache 1) 60k miles: liftgate came crashing down my wife's back while getting the groceries. they should have some safety measures to stop the gate from crashing. 2) 70k miles: truck wont start in drive way. towed truck to dealer and they changed fuel pump. 3) 70k miles: engine misfire code. replaced one coil. 4) 76k miles: coolant always low. dealer changed water pump. 5) 76k miles: truck hesitate and feel a misfire between 45 and 55 mph. took truck to dealer and they quoted me over $3300 to replace all coils, spark plugs, steering wheel column and steering rack busing. 6) since we bought the car we cant even drive it with the windows down or the roof open. the truck shakes roughly with both roof and windows open. *tr

When accelerating, my car seems to 'slip' or 'stutter' before clicking into gear. this happened in the first year of ownership. the dealership never acknowledged it when i would bring it in to get checked. after a few years of owning it i now know that it is a transmission issue very common with the gmc acadia. i have read that it is a faulty wave plate. not sure what that is but now with only 50,000 on my car it is really bad. it barely made it home last night. transmission is totally slipping and even when just driving along at the same speed it went into limp mode. the gas revved like i was in neutral. this is extremely dangerous as i had a carload of girls on a trip to the mountains. what is it going to take until this causes an accident and casualties! gmc needs to step up and get this part recalled. it is a faulty part and they need to pay for the replacement!!! *tr
