2010 GMC Acadia Likely To Need Engine Rebuild, Report Says

In a recent article, Consumer Reports pulled data from its Annual Autos Survey to determine which older used vehicles have the biggest chance of experiencing a major engine problem at some point in their lifetime. The Chevrolet Equinox and GMC Terrain are both included on the list, as we reported last week, with the crossovers well-known for problems with the available 2.4L four-cylinder engine. Those weren’t the only GM vehicles that may need an engine rebuild in their lifetime, however.
The 2010 GMC Acadia and its 3.6L LLT V6 engine are also included on Consumer Reports‘ list of vehicles with problem powertrains. The publication indicates the vehicle typically experiences engine trouble between 106,000 and 129,000 miles, though it did not list any specific problems associated with the six-cylinder engine in its article.
Some owner complaints submitted to the publication appear to indicate that some owners have experienced timing belt problems with the LLT V6 engine. One owner in Louisiana said the timing belt failed twice in the vehicle, but both times it was fixed under warranty. Another owner said the timing belt in their 2010 GMC Acadia failed at 50,000 miles, which led to significant damage and forced them to replace the entire engine under warranty. The timing belt in the new engine failed again after 50,000 miles, which also led to damage and required an engine rebuild. The same owner said that when going to buy a new vehicle “the dealership admitted to us that this was a bad year for this vehicle and the trade-in value was not very good.”
Consumer Reports has also received other complaints related to an engine oil leak and a “heavy buildup of carbon,” that led to engine trouble but did not require a complete engine replacement or rebuild.
While the 2010 GMC Acadia is a bit of a problem child, Consumer Reports has not received the same volume of complaints from owners of older and later model year examples of the crossover. It’s worth noting that the first-generation GMC Acadia went out of production in 2016 and the second-generation model offers a range of major improvements, including different available engines.

I have a 2012 Acadia. I kept getting a service stabiliatrac message then my engine power decreased and then it shut off. My car will not start. I owe more than it’s worth. GM needs to do something about this as it seems to be a reoccurring issue.
My 2010 Acadia needs a new engine due to timing chain with no warning, $6000 to fix. I still owe 2 years on it, it was bought used and have no warranty anymore. No car since February 12, 3030. CAN’T BELIEVE THERE HAS NEVER BEEN A RECALL WITH THIS RECURRING PROBLEM!
I have a 2011 Acadia with 160000Kms I have always change the oil every 8000 Kms with the best oil (Pennsoil) not the cheap cooking oil they sell at autoparts stores and pulling my 4000lbs trailer home. This engine purrs. No Problems. CHANGE YOUR OIL REGULARY. WITH QUALITY SYNTHETIC OIL and oil filter, don’t be cheap OR YOU WILL REGRET IT.
All of these comments that stick up for GM saying this and that about oil and what not are bs. I have a 2013 Terrain. Bought with 58000 on it. At 78000 it wouldn’t start in our driveway. Timing chain. $2100 repair. Now almost exactly 2 years later, went out on Christmas Day and of course it won’t start. Same issue. Oil changed religiously with Mobil-1 every 5000 miles. Now looking at another $2100 or more again. I’m done with GM forever.
Mines sitting in the garage for 2 years now with 101,000 miles and still owe about 2 years. I paid for the extended warranty, the warranty says it covers complete internal engine, transmission, and specifically lists timing chain, pistons, rods, bearings, etc. Until 16?,??? Miles. The dealership had my car for 7 months then called me to come pick it up and when I got there they handed me the keys and said GM refused to fix it because the cost was to high and couldn’t honor their warranty. Didn’t help me get it back home or anything.
My 81 year old mom’s 2010 Acadia timing chain failed at 16 k miles! They didn’t warranty it as it was past timeline. My mother could not drive it much due to my dad’s stroke that left him bedridden in her care. She’s an angel for caring for him at home till he passed and to buy the car brand new and it fail on her….I will never forgive GM for this. I had a 2007 and the chain failed in it while my son was using it at college. I loved the layout of the vehicle and encorgaged my mom to buy one. I feel terrible for recommending it. Hot place coming for this company in the future.
