Terrain

The power steering assembly failed and caught on fire. This then caused the engine to malfunction and no longer work. This happened while driving on the interstate at a speed of approximately 80mph. No prior check engine lights were visible

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.

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.

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.

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

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.

March 1, 2025, I was driving from Charlotte, NC east bound on highway 40 towards Wilmington and all of a sudden my car just stopped while I was in the left lane. I was able to cruise over to the right shoulder and park my car in front of a sign that read exit 298 a few feet ahead. From there I was on the highway about two hours trying to get a tow truck to tow my 2017 GMC Terrain to the nearest GMC dealership which so happened to be 10 miles away. Which the tow never came. My step father drove about 100 miles west to pick me and my daughters up. All night I was on the phone with one tow truck company after another and every one kept saying they couldn’t find my car. In the morning I called another tow and he was able to find my car in the same location I left it. It was a Sunday so I had to wait until Monday to follow up with GMC Thompson. They advised I needed engine work. I was told I needed, timing chains, compression, gear bolts. However my car had just been repaired in November 2024, because my car wouldn’t start up after work. GMC in Charlotte Liberty GMC they replaced the gasket, chains, pipes, pistons, bolts, screws, seals, valves, bearings, actuators, tensioners, manifold, I mean the engine was rebuilt basically. It Thompson GMC about month to repair the vehicle because they were waiting for parts. The last week Lisa my representative was able to get me a loner car. I’ve been driving the car for about almost 3 weeks and I’m still very Leary of it. Terrible experience and I don’t see any recalls for my year make and model but I believe I’m probably not the only one with this year make and model that has gone through this. There’s two dates so I’m not sure which date to put.

1st time - rear main seal blew out & engine lost all of its oil causing rocker arm to break & chains to slip-vehicle sputtered & DIED while driving down busy street & would not restart - my safety & safety of others driving behind me were at risk for causing a rear end accident and/or pile up crash - no warning lights or sounds alerted me - dealership told us General Motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in Midwest states due to colder temperatures - the intake manifold vent hole is not large enough to let air out, so it plugs up & causes pressure to blow out rear seal, which causes oil to leak out and engine dies. When replaced with a remanufactured engine intake manifold vent hole was not drilled out causing it to happen again 2nd time - when leaving parking spot at work noticed oil puddles underneath my vehicle, I checked my oil, it showed full, I was concerned, drove to nearby last place I got my oil change. They informed me that all the oil had leaked out and showed me the bottom of my vehicle oil covered the front to the back of my vehicle. They also said that I was extremely lucky to get to shop before engine blew and stopped dead. AGAIN my safety and safety of others behind me could have been a rear end accident and/or car pileup crash - again no warning lights or sounds alerted me - shop personal told me General Motors is aware this is/has been a problem with 2017 Terrain vehicles especially those driven in Midwest states due to colder temperatures - even though the repairs where done by a certified dealership the first time they replaced with a remanufactured engine but failed to drill out the intake manifold vent hole bigger so this would not happen again BUT IT DID. General Motors cannot just sell vehicles it has to stand behind what they sell which in my case they have not. Due to GM lack of concern, recalls, reimbursements, lives have been and continue to be at risk
