Any Original Owner High Mileage Terrains out there?

I have a 2010 Terrain 2.4L AWD that I purchased new that just passed 104K miles. I've had my share of the common problems listed on the forums here but overall have had a good experience with the car.

List of problems:

1. Engine started using oil at 32K miles. Since I check my oil regularly, I never ran low. Went from using a quart every 4000 miles to using a quart every 1400 miles now. I know that I can still get the dealer to put new piston rings in but hate to have the engine torn down if I can just keep adding oil. A lot of DI engines seem to be afflicted with oil consumption issues. I fly airplanes that use a quart of oil every 10 hours of running and that is considered acceptable as long as the compression is good!

2. Battery died and needed replacement at 53K miles.

3. AC Condenser cracked at 55K miles and was replaced (my dime).

4. HPF pump was replaced under recall 83K miles. Don't know if the original unit ever leaked or not.

5. Throttle Body Sensor issue at 87K miles. This actually happened to me while I was driving on a long distance trip. Had to pull over on the highway due to reduced power. Shut off the car and it ran normally after restart. Made it to my destination and installed a new Throttle Body myself (Advance Auto parts). No problems since.

6. Rusting of the door seams. I fixed this myself with seam sealing tape and a respray with touch up paint. This has held up quite well but the seam sealing tape is ESSENTIAL. Before this I tried just respraying but it re-rusted within a year.

My main worries now are the Wave Plate transmission issues. No problems yet but it seems like this affects a lot of these cars.

Would love to hear from other high mileage Theta owners detailing their experiences.

I would love to see this thread continue, unless there is already another similar thread. Didn't see one though. How many miles on those Equinox / Terrains?

2011 I4 2.4 Terrain here with 115,000.

Had the oil consumption problem, started around 70,000, had it fixed around 90,000 last year and it has fixed the problem. Other than that I have replaced the following...

1) Battery went last January. Almost 8 years so no complaints there.

2) Changed Spark Plugs at 93,000, only because the plugs were on rebate and are easy to do.

3) Did transmission fluid at 50,000 then again at 96,000.

4) Changed belt at 95,000 and just changed bad belt tensioner last month.

5) Low Beam bulb burned out a few weeks ago, replaced both sides. Got 8 years out of the OEM.

6) Rear brake pads are getting close, but still have some life. Fronts have half their life left.

7) Other basic stuff like air filters have been replaced a few times.

Other than that the car has given me no real problems. I do worry about the transmission, since the 2010-2011 have that stupid plastic disc design on the TCM which has been known to break around 120,000 - 140,000, I guess well see what happens.

Great to hear some actual input on these vehicles.. I'm wanting to get one.



Been driving my 2008 HHR Panel 2LT for over 10 years now & no issues. I replaced the battery just last year, it was still good, but going into winter I wanted to be sure..

If you can, get the V6, significantly less problems than the 4 cyl. If you do decided to go for the 4 do not buy a 2010-2013 unless the seller has documented proof the oil consumption problem has been fixed. Even then I would be weary.

Thank You for the input. I do want to find one w/V-6, (changing spark plugs looks to be a bit involved).
I'm reading so many oil issues with that 2.4 DI.

My 2LT HHR Panel 2.4 is a different animal I guess, it has never used a drop..

I"m searching for low mile 2016 or '17 V-6 (preferably) w/Denali package. I see several but they are not cheap.

I joined here to learn all I can as I look.. Appreciate any & all input..

Then there is choice between FWD or AWD, I know FWD should use less gas.

Personal opinion, unless you live somewhere that snows a lot, I wouldn't bother with the AWD. If you find a good one then go ahead, but the AWD is just more maintenance you have to do (transfer case, diff fluid) and you get slightly less gas mileage. Also the Denali's are nice, but they do come with the 19in tires. The 19's definitely look better in my opinion, but they will be more expensive to change down the road. Also the suspension system is different for Terrain's that use the 19in tires, so if down the road you have to replace struts, it will cost you more. Just something to think about.


Also here is a good video of a guy changing the plugs on a V6, it is a little more involved, but doesn't look terribly difficult.

That is a great point, enough to care for with inviting more. Also the Denali's are nice, but they do come with the 19in tires. True. The 19's definitely look better in my opinion, but they will be more expensive to change down the road. Yes they will, I have 20's on my old C-10..

Is the Terrain a sub-frame vehicle or full frame ?

Also here is a good video of a guy changing the plugs on a V6, it is a little more involved, but doesn't look terribly difficult. Thank You, I saw that U-toob previously. I think the V6 is still the way to go.

Thanks for all the input.
