2017 Gmc Terrain Complaints

  • Power Train, electrical System, engine 09/01/2025

    We have been keeping up with all maintenance and oil changes. We have only driven the car for less than a year. At time of oil change; the oil has been low, resulting in OVER oil consumption; Requiring an extra quart of oil to be added between oil changes. When we purchased the vehicle, there was an strong exhaust smell; The shop that we bought the vehicle stated there were no issues and we have taken it to them multiple times an hour away from our home. The car completely shut off while my minor son and I were driving. Placing both of our lives at risk! It would never start back up. Now the car has seized and requires an engine replacement. It is sitting at a local garage while we wait for the dealership to help us, to no avail.

  • Engine 07/15/2025

    I was driving back from out of state and all the sudden the engine just got loud. So I pulled over and check oil levels. Except there is no access to the transmission oil. The only way to check this is to remove the front driverside tire, take a bolt out and see if any oil drips out. This is insane that there is no dip stick. I am taking it to a mechanic on Monday but to not have quick access to this is wild.

  • Power Train, engine, fuel/propulsion System 06/18/2025

    Throttle position system all of a sudden went bad. My 2017 Terrain started shaking. I was holding up traffic. The sun couldn't go over 5mph. I've read online where this is happening alot in 2010'2017 GMC Terrains.

  • Exterior Lighting 05/25/2025

    I looked up my recall on my vehicle about my headlights being recall. Never received any information there was a recall.

  • Engine 04/10/2025

    GM recently recalled over 500,000 car engines. The warning signs to look out for was a “knocking” sound coming from the engine. I had recently experienced the same issues that the recalled car engines were experiencing. I went to get it checked out and my mechanic said there were chunks of metal in the engine. The GM engine recall should include 2017 GMC TERRAINS SLT. If I had not got it looked at, it would have caused an accident that would have been unpreventable due to the warning signs of only the knocking sound. No other lights had came on in the car. Please consider putting this make and model in the engine recall! If someone reaches out to me, I have the name of my mechanic that can verify the engine issue of my GMC.
