Yes...yes I did. But I see conflicting stories, so I was just enquiring about towing...didn't mean to get your panties in a bunch
I have a very light utility trailer i use. I try to keep total weight under 1,000 Lbs. No problems so far.

Generally towing for NON TOWING RATED vehicle is limited to 1200lb. This is a rule of thumb number. If you drive on flat surface, vehicles can tow a lot more without problems, but if you have hills or mountains, vehicle brakes, engine and transmission cooling system is not designed to deal with extra heat generated by trailer weight, that's why 1200Lb was considered safe limit.

Here are the datas for the identical Opel / Vauxhall Mokka X equipped with the two engines (138 and 153 HP) shared with their US cousin, the Buick Encore:

138 HP engine and trailer with brakes: 1,200 kg (2,645.5 lbs)
138 HP engine and trailer without brakes: 500 kg (1,102.3 lbs)

153HP engine and trailer with brakes: 1,500 kg (3,306.9 lbs)
153 HP engine and trailer without brakes: 500 kg (1,102.3 lbs)

These figures are valid for hills up to 12%, and a maximum altitude of 1,000 meters (approx. 3,000 feet above sea level. The maximum authorized towing weight decreases by 10 % for every 1,000 meters.

All figures taken from the Opel Mokka X Specification Sheet, dated 06-29-2017

All this implies of course that the car is equipped with a trailer hitch specifically designed for Encore / Mokka X and certified for these loads.

I hope this helps.

A company named CURT Manufacturing LLC sells US made trailer hitches for the Encore. Towing capacity up to 2,000 lbs.

But DRAW TITE has one that is certified for 3,500 lbs towing weight. This offers a towing capacity similar to those we have here in Europe, i.e slighltly superior to what Opel / Vauxhall has authorized for the car. We can order the Mokka X with a factory installed Hitch ( manufactured by Brink in the EU). I don't know why Buick does not offer that possibility for the Encore, it does not make sense.

No drilling or welding required. It is a simple bolt-on job, plus wiring kit and you're done.

You should / could send an email to Draw Tite in case you are in doubt. They will certainly provide all the informations you need.

OPEL/Vauxhall in Europe are offered with manual transmissions which does not need cooling , ENCORE does not have that option in US, its only Automatic. US version has different radiator with transmission cooler in it. Automatic transmission can and will overheat if vehicle is overloaded and cooler is not sized for that. So it not same vehicle in term of powertrains. As for hitch rating 3500lb, its only metal rating for hitch itself. You could I suppose get a 10 000 lb hitch made up for Encore, does not mean your vehicle can tow that much.

Opel/Vauxhall Mokka X are offered with Automatic transmission as well, so I believe that your worries are not that justified.
BTW, the 153 HP version of the Mokka X is or rather was only available in combination with AWD and Automatic. (It has been discontinued just last week, simply because PSA did not want to pay to update it and keep it conform to new EU emission norms coming next september. They hit Direct Injection engines hard. The 138 HP version remains available, either as FWD with Manual or Automatic or as AWD but only with 6 Speed Manual.the combination of AWD and Automatic was exclusive to the Direct Injection engine, this is what made it the favorite version in Switzerland were the extra torque is appreciated, for obvious reasons.)

The trailing capacity mentioned in my previous post is valid for both engines with Automatic as well. A hitch rated at 3,500 lbs makes sense for a car that can pull 3,306.9 lbs or even 2,645.5 lbs. I certainly would not recommend to tow a trailer that weights about as much as the car though! One has to be reasonable and keep a comfortable safety margin.
The reason why the Buick is supposed not to tow while the Opel/Vauxhall actually does, will always remain a mystery. (And if I asked Opel/Vauxhall why we do not have the folding front passenger seat that the Buick encore offers, I would not get an answer either.)

As far as I am concerned, I still have to be patient, as my car is still one month away on a Ro/Ro ship. And it is an AWD with Automatic AND factory installed trailer hitch!

A trailer towing package will typically include a heavy duty transmission cooler that is separate from the radiator.

I grew up with with two friends who both became auto master techs. They told me that once transmission fluid gets overheated it's ability to lubricate and protect the transmission is severely compromised. I always look to see if factory offered optional transmission cooler and have always installed one. Bottom line is if you severely overheat the transmission fluid, transmission failure will probably follow...

I have always replaced transmission fluid at regular intervals well ahead of recommended service interval in manual. If I were towing on the encore for any appreciable distance I would do it once a year. And if you overheat it, replace the transmission fluid immediately.

You could install a transmission cooler. But i would not install one on a modern car unless it is offered by the manufacturer. The reason being is that it will also be slower to come up to proper operating temp or may not be able to reach it at all. Which may bring on other problems. For example, many modern transmissions have a temp sensor in transmission and change shift points and avoid lockup in order to bring transmission up to good operating temp more quickly. If it can't warm up properly, You might see poor fuel economy or throw a code.....

And finally there is a big difference between emission rules in Europe and U.S. The biggest one being that the Europeans can have vehicle not meet emissions in order to protect the engine. This is a giant loophole. They can run rich fuel to air mixture in order to protect engine, which will run cooler and avoid overheating.

As you can see, I am an engineer who typically goes into way too much detail. It drives my wife crazy..... :)

Short answer to all of the above is that whether you can safely tow with your Buick Encore is not an easy question to answer....
