Expert Answers about GMC Terrain


  • Replacement Control Module and Door Sensors for Kwikee 32 Series RV Steps
  • The part number 1800709 was phased out and was replaced by the # LC379605 which is the correct controller for your 2008 Kwikee 32 Series step. The correct door sensors are then the part # LC369299 and you'd be set!

  • Roof Rack Recommendation for 2016 GMC Terrain to Use Thule Hullavator
  • I checked with Thule and they confirmed their 47 inch Wingbar Evo roof rack part numbers # TH711220, # TH710401 that fits your 2016 GMC Terrain does work with the current version of the Thule Hullavator part # TH898 so it would be the way to go. You aren't able to use longer crossbars most of the time as the attachment channel on the bottom side of the crossbar does not run the full length of the bar.

  • Can I Use The Thule Passage 3 # TH911XT On My 2019 GMC Terrain To Haul My Ebike?
  • There are options for getting your 62 lb ebike to the trails using your 2019 GMC Terrain, but a trunk mounted rack like the Thule Passage 3 # TH911XT is not the answer. Even though it has a capacity of 105 lbs, it still isn't recommended using a trunk mounted rack for hauling an electric bike as the capacity is for all 3 bikes loaded up and not just one bike. E-bikes need a platform style rack to be hauled. Your best option is to get a hitch like the Draw-Tite Max-Frame Hitch Receiver #...

  • Availability of Light Duty Weight Distribution Systems
  • We have very light duty weight distribution systems, but none of them will fit a 1-1/4 inch hitch since that hitch size isn't designed for the torque the WD systems can put on hitches. For a light duty weight distribution system that will fit a 2 inch hitch the Reese Light Duty part # 66557 is for tongue weights up to 400 lbs. If you need a higher rated system the part # RP66540 is for 200-600 lbs of tongue weight. For a 2 inch ball you would want part # A-90 and for a 2-5/16 inch ball...

  • Parts Needed to Flat Tow 2013 GMC Terrain Behind Motorhome
  • Yes, our flat towing recommendations are going to be the same for 2013 GMC Terrain as those for the 2012 model. In order to flat tow your Terrain, you will need the 5 basic components. I recommend going with the following: Tow Bar - RoadMaster Sterling All Terrain Tow Bar # RM-576 Base Plate Kit - Roadmaster EZ Base Plate Kit # 523163-1 Safety Cable Set - Included with Tow Bar # RM-576 Tow Bar Wiring - Also included with the Tow Bar Supplemental Braking System - Roadmaster Even Brake...

  • Trailer Hitch and Wiring Recommendation for 2017 GMC Terrain
  • For a hitch for your 2017 GMC Terrain I would recommend the etrailer part # e98865 which is a confirmed fit, with great towing capacities, and because it has the best price. For trailer wiring the Curt harness part # 56094 that you referenced is a confirmed fit, but I would rather see you use the Tekonsha part # 118494 as it has circuit protection built into it that the Curt does not. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes...

  • How to Find Which Transmission Cooler Will Fit with Your Vehicle
  • In order to determine which transmission cooler will work for your 2019 GMC Terrain (or any other vehicle), you will need to measure the amount of space you have in front of your radiator. For example, the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class III - Efficient, part # D13502, measures 11" wide x 7-1/4" tall x 7/8" deep. If you have this amount of space to work with in front of your transmission, then this will work for you. As for installation, we have...

  • Trailer Hitch and Wiring Recommendations for a 2016 GMC Terrain
  • Between the Curt hitch # C12291 and Draw-Tite hitch # 36408 both hitches are positioned the same on the 2016 GMC Terrain. Take a look at the picture I have included showing the hitches installed. The receiver locations are identical and the crosstubes and mounting brackets are hidden behind the fascia/bumper. If it were me I would use Draw-Tite trailer hitch # 36408 if carrying bikes or cargo. The reason is that the Curt hitch requires the use of stabilization strap # 18050 when using...

  • Recommended Trailer Hitch and Trailer Wiring for 2017 GMC Terrain
  • We have both Class III hitches with the 2 inch receiver tube or the Class II with the 1-1/4 inch receiver tube available for the 2017 Terrain. I'll typically recommend folks go with the 2 inch, as there are more hitch mounted accessories available and there isn't much of a price difference between the two. I'd recommend going with the etrailer brand # e98865 Class III hitch because it's very competitively priced and is just as high quality as the offerings from Curt and Draw-Tite. For the...

  • What Hitch and Wiring do you recommend for my 2014 GMC Terrain
  • The etrailer Trailer Hitch Receiver part # e98865 is a perfect hitch for you. It has plenty of weight capacity and looks really nice on the vehicle with its matte black finish. If you're hauling it on a trailer the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118494 will give you a working 4-way flat trailer connector to operate the lights. The etrailer Ball Mount Kit for 2" Hitches part # 989900 is a great way to have any ball and ball mount combo you...

  • Tow Bar Recommendation to Flat Tow a 2011 GMC Terrain with a Roadmaster Sterling Tow Bar
  • The EZ style base plates you have ordered are compatible with the Roadmaster Sterling Tow Bar, # RM-576, and nothing else is required to aid in ease of installation or removal. The tow bar comes with safety cables and a 6-pole connector. Both the towing and towed vehicles will need a RoadMaster 6-Wire Trailer Connector - Vehicle End, # RM-910030-7. Finally, you will need to check with the manufacturer for instructions on the proper procedure for towing your vehicle because some vehicles...

  • Why Circuit Protected Trailer Wiring for 2016 GMC Terrain is Better
  • The Curt T-Connector Vehicle Wiring Harness with 4 Pole Trailer Connector, # 56094, will fit your 2016 GMC Terrain and will work to operate the trailer stop, turn, and tail lights. But, it does not have a circuit protected or powered converter to protect your vehicle wiring. If given the option, I will always recommend the circuit protected powered converter, # 118494, because it is designed to protect your vehicles sensitive wiring. What it does is virtually eliminate the extra power...

  • Vehicle Taillights Shut Off with Trailer Plugged Into a 2012 GMC Terrain
  • There could be a few different issues with your setup but since you have towed the trailer with your other tow vehicle and there were no issues then that means the issue is with your 2012 GMC Terrain. I did not catch what trailer wiring harness that you were using but the first thing I would check is the ground for this harness. This is most likely the cause but if the vehicle's taillights are also cutting out then that leads me to believe you could be overloading the circuit. If you are...

  • Comparing Blue Ox Patriot and Demco Stay-IN-Play Braking Systems for a 2017 GMC Terrain
  • In regards to braking systems, there are portable options which take a bit of time to setup but can easily be transfered for vehicle to vehicle and there are fixed options which don't really require any setup but are not easily transferred from one vehicle to another. The best two options in these categories are the Blue Ox Patriot Portable Braking System part # BLU37TR and the Demco SBS Stay-IN-Play DUO Supplemental Braking System part # SM99251. These will both work just fine on a 2017...

  • Can a Prodigy P3 Brake Controller Install in a 2011 GMC Terrain
  • You can definitely install a P3 Brake Controller part # 90195 on a 2011 GMC Terrain but there isn't a plug-in adapter available for it. You will need to start with a 4-way (if you do not have one). For that you would want the # 56094. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for...

  • Can Larger Tires Be Put on CE Smith Multi Sport Plus Boat Trailer
  • The CE Smith Multi Sport Plus Boat Trailer # CE48870 referenced in your question includes 12 inch wheels and tires. You could certainly replace these with larger tires but you will need to make sure you maintain adequate clearance between the fenders and frame rails. We recommend at least 4 inches between the fender and the top of the tire for suspension travel and at least 2 inches between the tire's side wall and frame. The hubs on the trailer feature a 5 on 4-1/2 inch bolt pattern so...

  • Weight Distribution Hitch Recommendation for Towing 2019 Jayco 145RB
  • A weight distribution system is recommended basically whenever the trailer weighs over half the weight of the tow vehicle or the suspension of the vehicle is experiencing significant sag. You'd be over the 50 percent weight capacity so a system would be recommended. I'd recommend the Strait Line part # RP66082 which has a tongue weight range of 200-600 lbs and features the best style of sway control that works to fight sway before it starts. For a 2 inch ball you would want part # A-90...

  • How Do I Flat Tow My 2011 GMC Terrain With A 4Cyl Engine
  • Your 2011 GMC Terrain can be flat towed if it is FWD, not AWD. You will need the following items to flat tow your vehicle: base plate, tow bar, supplemental braking system, vehicle tow bar wiring, and safety chains. My recommended base plate is the Blue Ox Base Plate Kit - Removable Arms, part # BX1689. You cannot see this base plate when it is installed, yet it is always ready to be towed. I have included a video of this base plate being installed on a 2012 GMC Terrain below. The next...

  • Best Trailer Hitch for a 2018 GMC Terrain with a 1.5L Engine
  • For your 2018 GMC Terrain with the 1.5L Engine I recommend going with the Draw-Tite Max-Frame Trailer Hitch Receiver # 76419. This is a Class III hitch with a 2" receiver with a 4,500 lbs Gross Trailer Weight (GTW) rating and a 675 lb Tongue Weight (TW) rating. It is the perfect trailer hitch for many different applications but you will want to check your owner's manual to verify what weight capacities yor Terrain has. Let me know what you will be using the trailer hitch for and I can...
