2015 GMC TERRAIN Complaints

In October 2021 I took my car to have brake pads replaced, oil and filter change, and tire rotation. The day before the appointment the engine light came on. I parked the vehicle and waited for my appointment. The mechanic there told me there was not a drop of oil registering on the dipstick.... very odd considering I had the oil changed regularly. The appointment was completed and the engine light reset. The next day the engine light came back on and the code it was giving was for a Timing Control Solenoid, so I purchased the parts and took it back to the same mechanic. Engine light off- vehicle running normally- a few months pass-another routine oil/filter change in between and the engine light comes back on. This time I take it to a dealership and again there is not a drop of oil registering on the dipstick. Now it is sitting in the dealership garage waiting on parts to arrive to replace the entire timing chain assembly. I have read many complaints in the last several months about the same issue. This should have been a recall by now. If the timing chain were to snap it could cause heavy engine damage as well as an accident if on the road at the time. GMC needs to be made aware of this situation and the heavy consumption of oil. My mileage at this time is only at 82K - this should not be happening this early on.

It was snowing. I cleared all the snow off my vehicle and warmed it up. I went to turn my wipers on, and they didn't work. The wipers just won't turn on.

The contact owns a 2015 GMC Terrain. The contact stated that upon checking the oil reservoir, he noticed that the oil was low despite recently having an oil change performed. The contact replenished the oil; however, he began to notice that the vehicle was vibrating with the check engine warning light illuminated. The contact took the vehicle to three independent mechanics; the first two were unable to diagnose the failure; however, the third dealer diagnosed the vehicle with a defective camshaft phaser. The contact called the dealer about the failure; however, they were unable to offer any assistance. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 152,000.

Check engine light on took to dealer and they ran diagnostic. Timing chain is also on its way out. I am the original owner. "Water in PCV system obstruction in the secondary air system." I had this cleaned out a few years ago $500.00. If the PCV freezes without warning, the engine will seize. No warning for PCV, just visual inspection from tech at dealer.

I was driving home last evening in the rain and with no warning my windshield wipers quit working. My visibility was severely impaired and this could have caused a very serious accident.

When I entered the vehicle to drive on a rainy day the windshield wipers would not come on after I moved the arm up. They would sometimes work when on "INT" but would not stay on and they would not work at all in the low or hi mode. There were no warning lights on. There has currently been no inspection. This caused me to have to drive home in the rain with poor visibility because the wipers would not work properly, as the "INT" mode would turn on and off randomly and not in the typical pattern on "INT" mode.

The contact owns a 2015 GMC Terrain. The contact stated that while reversing out of her driveway, the vehicle started making abnormal knocking sounds. The check engine warning light illuminated. The contact parked the vehicle. An independent mechanic diagnosed that the battery was severely corroded and needed to be replaced. The contact stated that the battery was replaced; however, the failure persisted. The dealer and the manufacturer were not notified of the failure. The vehicle was not repaired. The approximate failure mileage was 113,000.

As I was navigating my way home on Nov. 3, 2021 the windshield wipers stop working and it was dark and pouring down raining. There was no warning. Then the radio started acting weird the bluetooth went away and I could not get it back on the screen to connect. I tried turning on and off the radio but it would not turn off. The biggest danger to my life was that I could not see so I had to keep pulling on side streets to wipe the windshield so I could make it home in the dark and pouring rain. When the bluetooth stopped connecting I had to pull over again and pipe the directions through my phone to continue to navigate home. The windshield wiper can be confirmed by the dealer because it still did not turn on today. The radio turned on and off today and the bluetooth icon was back.

This is NOT a vehicle issue, but an issue of Wiper Blade manufacture. I Purchased Michelin Guardian wiper blades for my 2015 GMC Terrain which has the large PTB arm latching system. The Michelin blades do not latch securely into the arm and can be easily removed by hand without touching the latch release. My concern is the blades may become unsecured by normal usage and fly off the vehicle leaving the driver stranded who knows where. My thought scenario is between rest areas on the Indiana Toll Road between the Ohio state line and Chicago, IL. Imagine a retirement aged senior citizen in such a predicament. I have replaced the Michelin blades with Rain-X which latch securely and will return the Michelin blades. My concern is for the un-aware, un-suspecting driver who may experience the latch failure I have described. FYI, Michelin has not responded to my correspondence to them on this issue.

On 10/25/2021 at approximately 5:40 AM, I was on my way to work. It was raining and dark at that time so of course I had the wipers on. As I proceeded to get onto the highway, the wipers completely stopped as I exited the on ramp. Immediately I had to maneuver to the shoulder of the highway. Considering I couldn't see that could have easily been an accident since my visibility was 0 as well as being parked on the side of the highway for a prolonged period. My husband came and traded vehicles with me. He eventually got my vehicle off the highway and to a repair shop where they diagnosed the problem: the wiper transmission went out. The vehicle has not been inspected by anyone. There were no warnings that this problem was going to occur
