2014 GMC TERRAIN Complaints

Driving and there was a thump and the right windshield wiper arm came to a stop in the middle of my windshield and would no longer work during a downpour.

On an extremely rainy day, the windshield wipers stopped working. My son was driving the car, and his safety was extremely compromised. He could not see out the windshield at all, and he was lucky that he was in a position to get to the side of the road without incident. If he were on a highway, it would have been extremely dangerous. This occurred on July 8th, 2021. There were no warnings that precipitated the problem. The wipers were working fine. We went to our mechanic who had to replace the entire windshield wiper mechanism due to corroded joints. We paid approximately $260. The mechanic said this is a very common problem with GM wipers. We did not keep the damaged part... we did not know that this was a safety issue with other model GMC Terrains until today. Clearly, it is a widespread problem, and there should be a recall, as this is extremely dangerous

I was driving to work during a rain storm. I drove for about 25 minutes until I reached the highway. I merged onto the highway behind a tractor trailer. There was enough spray that I needed to put the wipers on high speed. After driving for a few minutes the wipers came down and stopped halfway. I was able to pull over on the shoulder and tried to determine what happen. I turned wipers off and on and could hear the wiper motor whirring. Motor worked but wipers did not engage. I got out of the vehicle and pushed the wipers down and they moved freely telling me they are not connected to the motor. This was very dangerous and scary! I am now in need of repairing this issue.

For the last 6 months my vehicle has excessive oil consumption 1/4 to 1/2 quart of oil every week. When it starts up it sounds like a diesel engine. In 2019 it did the same using about a 1/2 quart every 3 weeks. We have kept an eye on it ever since as over time it has increased oil consumption and just recently found out this is a problem for many others as well. We have always kept the oil changed when due per mileage sticker and vehicle oil life indicator.

While driving in a rainstorm, the wipers stopped working. This caused my visibility to suddenly become extremely compromised. A tractor trailer was in front of me and spraying water from the tires due to heavy rain as well. I had to pull over, under an over pass, and wait out the rain. This is extremely dangerous in of itself to be on the side of a major highway. I have since investigated and found the ball joint connection to the wiper arm corroded and broke off. The wiper motor still runs. This is identical to the 2013 GMC terrain issue.

While driving in the rain, my windshield wipers just stopped working while in an upright position on the windshield. Not only could I not see due to the rain, the wipers were actually blocking my view as well. They now will not turn on at all.

I'm having issues with my GMC Terrain when I start it. It always starts but it's like it keeps trying to start or is having issues getting enough fuel to get it to idle normal. Sometimes it only lasts a second or two and other times I have to push the gas pedal to get it to idle normally.

My GMC Terrain makes a clunking noise under the hood when I accelerate and go into a lower gear. Does it mostly going up hills but also even on flat road.

The contact owns a 2014 GMC Terrain. The contact stated while driving at various speeds, the vehicle hesitated while depressing the accelerator. The service engine warning light was illuminated. The contact had taken the vehicle to several independent mechanics and was informed that the catalytic converter needed to be replaced. The contact then took the vehicle to the dealer and it was confirmed that the catalytic converter was defective and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 140,000.

My 2014 GMC TERRIAN WIPERS STOPPED WORKING. I CAN HEAR THE WIPER MOTOR RUNNING, BUTWIPERS NOT MOVING. THIS WAS VERY DANGEROUS AS I HAD TO MAKE AN EMERGENCY STOP DURING HEAVY RAIN WITH LIMITED VISIBILATY.
