Concerns about Buying a Terrain Diesel

Hi All-

I live in the Northeast and have a long daily highway commute averaging 35k miles per year. My golf cart of a Hyundai that I currently drive has been flawless but at 175k miles, it needs to go out to pasture soon before it needs any major repairs. In addition, I want to tow a small aluminum fishing boat (8-10 times a year) and a new little Hyundai won't be up to the job. I'm spoiled by Asian car dependability and getting 32-35 mpg.

Enter the Terrain Diesel

I've test driven the Terrain Diesel and loved it. My thought is to wait until next February or so and buy a 2018 vehicle coming off a lease - hopefully maintained at the dealer from which I make the purchase. I'd buy the longest most comprehensive GM extended warranty and keep my fingers crossed.

My problem is that I've had so many bad experiences with GM products since I was a kid that I think I might have automotive PTSD - mostly from suffering through a 1980 Olds Omega, and 2002 Saturn L300. I know that GM is a lot better these days, but the Chevy cruise engine debacle was recent and I can't unsee the Pontiac Aztec. Fact is, if my car doesn't run, I don't get to work and have to rent a vehicle. So there is a lot at stake.

Am I just being neurotic about this, or should I be concerned about trusting this car to take me to the 200k range without reliability issues. In fact, the money for maintenance and repairs is much less important than the feeling of not having a car I can trust. I'm the type that tends to over-do maintenance and get things done the second there might be a problem.

What would you all do? Any help is greatly appreciated.

Glen

That's one of the issues with a diesel you're not supposed to tow with it....

Hmmmm. I sense some sarcasm. ;-)

The issue is not so much with a diesel. It’s with this diesel, which I understand is French in origin. But the larger question is about the reliability of the new Terrain design as a whole. This diesel’s performance, common issues, stated vs. actual MPG. Any known issues I should look out for, etc.

Those that have them, are you satisfied. Would you buy one again?

Thanks in advance.

No sarcasm... I lease one gets a constant 36-37 mpg no issues with the drivetrain but it only has 14000 miles on it
Don't like the gauge for the DEF and the fuel filter could be a concern down the line as could be the DEF pump as the cold can effect it.
It rides nice has good power but I dont think I would buy one now that they are discontinued

I see what you’re doing here - you get the diesel a year old at a huge discount - plus, what (?) ... 45 mpg? Not a bad idea, but wouldn’t the gas Equinox or Terrain be the better choice? You’ll still get upper 30’s mpgs, and the fuel will be cheaper.

I guess I’d have to see both purchase prices ...

Hey Glen! I researched my decision to get my 2018 Equinox Diesel AWD Premier for months prior to pulling the trigger. I did what you plan on doing and found a used one with 4Kmi for $27,100; that was a huge savings over new. I immediately changed the oil myself after purchase and just let the dealer do the first of two free oil changes after just breaking 12Kmi. Real world fuel economy on the highway is just over 41mpg WITH flowing traffic and just under 40mpg without it. The longest trip so far from Sarasota, FL to Miami yielded 42.3mpg. The towing rating of 1500lbs is because the DEF tank is in the way of installing all six bolts into the hitch. Someone else here on the site figured a workaround for that. This engine has been utilized in Europe in Opel vehicles and in Australia in Holden vehicles and don’t seem to have any glaring issues (at least none that I could find). I hope you’re as happy with yours as I am with mine. Best of luck!

If you buy cheap, you buy twice!

Indeed it is this diesel as designed ...as mentioned in articles at when the 2018 nox was getting ready to be released...they have not provided enough cooling for this diesel to tow more that 1500lbs.

BTW it is German designed ...though Opel now is owned by Peugeot, France

https://en.wikipedia.org/wiki/GM_Medium_Diesel_engine


We love our diesel nox...we don't need to tow at all, but we drive a lot of highways and rural/state highways...Our average mpg for 22000 miles we have driven this car is 37 mpg. Love that i refill after 400 miles and still have a couple of gallons still in the tank.


But i am partially worried with it being discontinued ...if i were on the market today for a new car i would not buy it just because it is being discontinued...i tend to keep cars for 10 to 15 years...so i wonder if that would happen with this one once our extended warranty is over.

If i were on the market today the 2019 hybrid rav4 would be a good option as highway miles are close to the diesel nox
But then does the batteries last more than 7 or 8 years (the warranty period).

I had no idea it had been discontinued. Thats too bad. Well maybe if they are discounted way low because of the discontinuation I’ll take the chance since those of you who have them like them. Otherwise, I’ll check around for other options. The little bass boat i want is right around 1500# so any of the mid sized SUVs will do it. If I can swallow low 20s MPG, there are almost countless options.
Thanks for all of the feedback!

Anyone know why the diesel went away?

Same reason(s) *any* product goes away: didn't make enough money. Lack of interest.

But hey - if someone *gave* me a diesel, I'd take it and drive it my requisite 222,222 miles.

Probably wouldn't have much trouble doing it, either ...

One other thing to consider is GM May have discontinued the Trailer hitch that can be installed after purchase? I’m not sure if there is enough demand for a 3rd party to make one, so try and find one already installed.
