This Is Where The GMC Terrain Is Made

This Is Where The GMC Terrain Is Made

We’ve written extensively about the GM Terrain and its capabilities on this blog. Today we’re going to look at where the Terrain is made. This seems to be a straightforward question, but this car consists of many components (engine, transmission, tires, etc.) made in different parts of the world. Let’s start with a quick answer:

Between 2010 – 2017 GMC Terrains were assembled in Ingersoll in Ontario, Canada. From 2018 onwards, Terrains have been assembled in San Luis Potosi, Mexico. The engines that have been used in the two generations of the Terrain have been manufactured in Michigan, Tenessee, and New York, as well as St. Catharines, Canada, and Coahuila, Mexico. The transmissions are mainly made in Ohio, Michigan, and Mexico.

However, that certainly doesn’t answer the question entirely. Below, we’ll first dive into detail about the assembly location. After, that we’ll give you the complete rundown of where the engines are made, and we’ll do the same for all transmissions used in this vehicle. Finally, we’ll talk about how to identify which tires you have and where they are manufactured precisely. Read on!

Assembly Location Per Generation

The first generation of the GMC Terrain, manufactured between 2010 – 2017, was assembled at CAMI Assembly in Ingersoll, Ontario in Canada. The second generation, manufactured from 2018 onwards, is assembled in San Luis Potosi in Mexico.

Now, it’s essential to discuss the engines that are used in the GMC terrain. The first generation of the Terrain used four different engines. Below we’ve stated what engines these are and where they have been manufactured.

  • The 2.4 Ecotec LAF manufacutred from 2010 – 2011 and the 2.4 Ecotec LEA manufactured from 2012 – 2017 where both built in Tonawanda, New York.
  • The 3.0 LF1 or LFW manufactured from 2010 – 2012 and the 3.6L LFX manufactured from 2013 – 2017 where both manufactured in four locations:
    – St. Catharines Engine Plant, St. Catharines, Canada; 
    – Flint Engine South in Flint, Michigan, United States; 
    – Romulus Engine Plant in Romulus, Michigan, United States
    – Ramos Arizpe, Coahuila, Mexico.
  • The Natural Gas versions of this generation of the Terrain aren’t made by GMC. Instead, they are modified by Nat G GNC Solutions in Houston, Texas and AGA Systems in Salt Lake City, Utah.

The second generation of the GMC Terrain uses three different engines that are made in the following locations:

  • The 1.5L LYX Turbo Inline-4 is made at the Flint Engine Plant in Flint, Michigan.
  • The 1.6L LH7 Turbo-diesel Inline-4 was made in Szentgotthárd, Hungary.
  • The 2.0L LTG Turbo Inline-4 was made in multiple locations, to include Spring Hill Manufacturing, in Spring Hill, Tennessee while the engine block and cylinder heads are cast at Saginaw Metal Casting Operations in Michigan.

Now, let’s talk about the various transmissions used in the GMC Terrain and where they have been manufactured. Below, we’ve created a list of the transmissions and with the exact model numbers. Let’s have a look.

First Generation (2010-2017):

  • 6-speed 6T45 automatic for I4 Models are manufactured in several different locations around the world. Namely in Toledo, Ohio – Boryeong, South Korea – Yantai, China
  • 6-speed 6T70 automatic for V6 Models are manufactured in at the Warren Transmission Plant in Warren, Michigan.

Second Generation(2018-Present):

  • 9-speed 9T45 automatic for 1.5L and 9-speed 9T50 automatic for 2.0 L are manufactured in the San Luis Potosi plant in Mexico
  • 6-speed 6T45 automatic for diesel 1.6L is made in three different locations around the world as mentioned in the previous subheading.

It’s challenging to give conclusive information about what brand of tires come stock on the GMC Terrain. Searching through forums, we found that many first-generation owners of the GMC Terrain had 17″ Firestone Destination on them from the factory.

According to, Firestone manufacturers tires in several different locations of the world, such as Brazil, Canada, Costa Rica, the U.S., and Vietnam.

Unfortunately, GMC has no further information available about what brand of tires come stock on the Terrain. Therefore, it’s impossible to give information about this. However, there is a way to figure this out yourself.

Suppose you want to know exactly where the tires of your GMC Terrain are made, then you can look up the DOT code on the side of your tires. This code is not that large, so you’ll have to take a moment to find it. It’s an extended code of letters and numbers that starts with the letters ‘DOT’. DOT stands for Department Of Transportation.

After the DOT letters, you’ll find a combination of three letters, numbers, or a mix. For example, ‘1M3’. In this case, 1M3 indicates Michelin makes the tire in Greenville, South Carolina. You can search on the internet for the specific three number/letter combination you have to find the exact manufacturer and location where the tires are made.

Are GMC Terrain American-Made?

Both generations of the GMC Terrain aren’t American-made because they are assembled in Ontario, Canada, and San Luis Potosi, Mexico. The engines for the Terrain are mainly manufactured in Michigan but can also come from Canada or Mexico. The transmissions are primarily sourced from Michigan or Mexico, whereas the tires for the Terrain are sourced from five different parts of the world.
