  2. 2007-2009 Acadia Transmission Failure

    The 6T70 and 6T75 transmissions in early Acadia SUVs are known to slip and overheat due to design defects. But the real problem is a busted 3/5/R wave plate that can destroy the entire transmission in a near instant.

  3. Shift to Park Warning Message

    Leaking coolant from a cracked intake manifold gasket is an extremely common problem on most GM vehicles made from the late 90s to the mid-2000s. Most experts agree that the problem stems from GM's 'DexCool' coolant which erodes away at the…

  4. GMC Overstated Acadia MPGs

  1. Acadia owners are tired of seeing a shift to park message when their gear shift lever is already in PARK.

    A new lawsuit says the problem prevents owners from shutting off or locking their vehicles. In addition to losing the ability to shut off and lock the SUVs, owners claim they must resort to all kinds of theatrics to get the SUVs to recognize they are in PARK. Drivers also say the batteries drain and GM has no clue how to fix the issues.

    We’ve seen complaints about this problem in both the 2017 and 2018 model years.

  2. During a crash sensing diagnostic modules (SDM) detect the impact and send a signal to the airbags to deploy.

    But according to CarComplaints.com, the SDM in the 2018 Acadia might not be powering down properly when the SUV is turned off. The module may stay deactivated when the SUV is restarted, showing an airbag warning light to the driver and a message that says “service restraint system." Additionally, a driver will hear warning chimes indicating the airbags are off.

    Basically, if it doesn’t shut down properly it won’t be able to turn on properly the next time the SUV is restarted. If that sounds familiar, GMC was part of a massive recall for similar module problems last year.…

  3. While you're probably still digesting that extra serving of holiday cookies, here's something else to chew on

    – GM says some 2017 Cadillac XT5 and GMC Acadia SUVs will have diminished braking ability because of hydraulic fluid leaks. Engineers found an oversized front caliper piston bore had allowed the piston seal to leak hydraulic brake fluid and it was determined the oversized bore can prevent the proper compression of the caliper piston seal.

    GM says a red "BRAKE" warning light will come on when this happens. So if you see that, stop driving as soon as possible – which in these SUVs could take quite a while. The bad caliper assemblies are on Acadias built between 04/19/2016 and 04/22/2016

  4. Back in May GM admitted that they overstated the fuel economy on some 2016 SUVs

    and offered a compensation program as a sorry 'bout that. Owners received somewhere between $450 to $1500, based on a few factors, for their troubles. But that wasn't enough for some.

    A new lawsuit wants GM to pony up more cash for the decreased resale value of the 2016 Chevy Traverse, Buick Enclave, and GMC Acadia.

    "The GM lawsuit says consumers who purchased those SUVs believed the vehicles were EPA-rated at 17 miles per gallon in city driving and 24 miles per gallon on the highway, resulting in a combined rating of 19 mpg. However, the plaintiffs say the Traverse, Enclave and Acadia are in fact rated at 15 mpg in city driving and 22 mpg on the highway, resulting in a combined rating of 17 mpg."

    Listen, I get it – GM advertised one thing and produced another. That's no good. But if someone is looking to buy a large used SUV, then I'm not convinced that 2 MPGs are a deal breaker.

  5. GM admits they dipped their hands into the fuel economy jar and pulled out a couple more MPGs than they should have for the 2016 Acadia.

    Well, I guess dinner is spoiled now. While exact amounts are unknown, owners should soon expect to receive compensation ranging from prepaid debit cards to extended warranties.
