2010 GMC Acadia Owner Comments

problem #12

Sep 072021

Acadia SLE 3.6L

  • Automatic transmission
  • 100,000 miles


Timing chain stretch is often related to low lubrication and most owners probably only put 5 quarts oil in during an oil change like I was doing. The refill amount is 5.5 quarts which means most people are under-filling by a half quart and often are not checking the level. I have found that adding most of another quart around 50% oil life is needed on my Acadia to maintain full level. The 5.5 quart refill is extremely inconvenient since most auto parts stores sell oil in 5 quart jugs and cost for a single quart always seems high. Also, I only use Mobil synthetic oil which is good but probably just as good as another synthetic oil at the proper fill level.

Let me know if you don't agree or if this extra info helps you prevent the dreaded chain stretch.

  • Automatic transmission
  • 52,441 miles

A 2010 GMC Acadia with only 52441 miles should not need a timing chain replacement. The vehicle has been well-maintained, garaged and literally driven mostly by a "little old lady". Mostly around town driving, some highway. This is a known issue for this engine, yet there is no recall, although special arrangements were made for the 2008 and 2009 models. Problem still isn't fixed from what my research turned up for subsequent years.

  • Automatic transmission
  • 120,000 miles

Hello, I started off by noticing my car shake a few times and had the check engine light on. So I took it to get checked..... found out, it was some oxygen sensors. After those were changed I took it to get an oil change, keep in mind my engine light is still on and the guy who was supposed to change my oil stated that my vehicle had a recall on the timing chain and that he wasn't going to be able to make an oil change until I got it replaced. And, that it was supposed to get it fixed at the dealer place which is the gmc, beck and masten close to where I live since it was a manufacture recall. I took it and they kept insisting that there was no recall on it and try and charge me to get it replaced. I am beyond upset about this. If its a recall problem why try to charge me to get it fixed? Please help me out here. Thank You.

Acadia SLT 3.2L

  • Automatic transmission
  • 52,739 miles


My husband just bought me the Acadia. I love it, don't get me wrong, but what makes me mad the most is the car lot sold it to me knowing it didn't pass emissions! They knew the check engine light wasn't working! I just took it to an auto part store because it kept dropping rpm's! It's reading 23 codes wrong with it!!!! Not only that, I just found out I have to replace my timing chain!

Acadia SLT 3.6L V6

  • Automatic transmission
  • 80,129 miles

At 80,000 miles the timing chain needed to be replaced on my 2010 GMC Acadia, they said it had stretched out, and needed to be replaced, $3,500, this was on 12/2017. On 8/2017, the check engine light came on and once the code indicated the chain needed to be replaced. Since it had been only 8 months since it was replaced, they did an oil flush, put in new oil, and reset the check engine light. This worked until 1/2018, 95,000 miles, when the check engine light cam on once again, and the codes indicated a stretched timing chain that needs replacement. Of course past the warranty of the car, and also the previous replacement. Looking on the internet, this seems to be a prevalent problem that maybe GMC should be taking care of.

Acadia SLT 3.6L V6

  • Automatic transmission
  • 114,000 miles

This is first and last GMC product i will own! A timing chain should last for many hundreds of thousands of miles. This type of failure is related to BAD engineering that's not backed by a Quality Company :(

Acadia SLE 3.6L V6

  • Automatic transmission
  • 69,000 miles


Timing chain should not need to be replaced at 70k miles. This was a major inconvenience as I had purchased the car a week before the P0008 code light came on. This is something that GMC should really cover under recall, but they will not.

Update from Apr 26, 2017: Kept getting the P0008 code intermittently for a couple months. It would come on for a day then go off. Then go a week to even 3 weeks without coming in again. In all it probably came in 5 or 6 times over the course of 2 months. Finally my mechanic decided to change the timing chain and associated parts under my extended warranty. This was just done a couple days ago, but the light has not come back in.

I'm hoping this fixed the issue and this time the chain will last the life of the car. Crossing my fingers.

Dec 012016


  • Automatic transmission
  • 104,000 miles

My Acadia had the timing chain replaced at 65000 miles. And now again at 104000 my chain is being replaced again. Gmc has extended the warranty for other years of this model to 120000 but my timing chain was only guarenteed for FOUR MONTHS. How is that possible when GMC has acknowledged a problem with the timing chain stretching but will not guarenteed my repair. The won't even help with the 3200 dollar out of pocket cost I have incurred due to their faulty product which they do agree exists. I would like some compensation for my replacement of this timing chain.

Acadia LS 3.2L/V6

  • Automatic transmission
  • 66,100 miles

When I purchased this car in August 2012 as a Pre-Certified 2010 Acadia I was excited. It was a nice car and met my needs. I had already needed to take it in by May 2013. Since that time it has been in for service work 8 times in the last 4 years. I had to have recalls done, new brakes, coolant leak, thermastat fixed, sterring column, throttle (last week) and now this week the timing chain needed repair- for this fix they have to take apart the engine $$$$. Granted some cost were covered but some were not. The timing chain is not covered and it is going to cost around $2500.00. Happy f*** Valentines Day. I called GMC since it only has 66,000 miles on it. They told me there was nothing they could do, all the warranties were over. They did not help. It makes me saddened that a car with only 66,000 miles is giving me so much trouble. I was hoping to have it paid off by now but because of all the fixes I am not. Will likely not buy a GMC again d/t the trouble I have had.

Acadia SLT-II 3.6L

  • Automatic transmission
  • 97,000 miles

If not for the years on the vehicle (6+) this would have been covered under the 100,000 mile powertrain warranty. Requested GM assistance, but was denied (all I wanted was a 50/50 split). My points to them being that it is under 100,000 miles and timing chains are intended to last much longer, oil changes were all done prior to oil life monitor dropping below 25%, and all other maintenance was done timely. Oh, and timing chains aren't supposed to stretch!

This repair involves dropping the engine!!!! If this was meant to be replaced the vehcle would have been designed differently. Many vehicles require a timing belt (not a chain) to be replaced. As far as I know none of those require engine removal or cost any where near $3,000 (probably not even half of that).

Let's also look at the extra coverage provided for 2007 and 2009 model years for just this problem - stretched timing chains. Come on GM you should be ashamed of yourselves. This is why other manufacturers are all passing you by.

Acadia SLE 3.6L

  • Automatic transmission
  • 140,000 miles

Now it Jun 2016, I heard a rattling noise coming from under the hood of my car and dealership said that my TIMING chains needs to be replaced and also I needed a purge solenoid, shock and struts. Total bill will be around $3,500. This car has made me so depressed. I'm so disappointed with General Motor. Oh, by the way, they did offered me $2,000 on a purchase of a new GMC, or Chevrolet car .

Acadia SLT 3.6L V6

  • Automatic transmission
  • 80,000 miles

Bought our Acadia with 70k miles on it, within the first week it had to have a fuel pump assembly due to a bad sending unit, drivers side headlight assembly due to it melted, and a list of other small things. After a little arguing the dealership repaired it. Records showed they always serviced it at the dealership and kept up on the maintenance. In 10k miles I've serviced it 3 times already. Check engine light comes on and stores a code p0008. Which is for the timing chain being stretched or worn. Daytime running light is out and the housing is melted on the passenger side this time. Remote start doesn't work and this is the first we've tried using it since its just now getting cold here. Dealership let me know that nothing is covered and GM would be no help. Going to try going higher up, there is no way a timing chain should be worn out at 80k miles. And headlight assemblies should not melt with factory bulbs in them unless they were designed or manufactured wrong.
