GMC Terrain 2017 SLI

Just recently purchased the 2017 model SLI, I really liked the look the feel of the car, it is a big upgrade compared to my 2006 Pontiac vibe. Few issues I have with it already.
1) clunky noice when turning
2) rear thud noise while idling or parked
3) engine steam

Engine steam seems to happen randomly either just sitting idle parked after a short drive, or after a long drive and just in park. I took a photo of the engine that looks to be smoking but it's steam of the heat it is giving off, I was able to capture the picture during the night while raining you can hear the sizzling of the water when it hits the engine or radiator.
Rear thud noise seems to come from the rear axle area passenger side at first it was loud enough I thought it was some one closing the trunk to their car, later I found it to be in listed area. After parking and standing near the rear passenger side you can barely hear it out side but inside it sounds very loud. After the car has been shut off you can hear the hot metal of the car cooling down in chicagos 40-50 degree weather then the big thud noise can still be hurd.

Clunky noise while turning sounds just like it is. Clunky noise when turning the wheels fully one direction.

I have not seen anything posted about the 2017 models yet only older 2014-2015. Has anyone come across this or these issues?
The car has 3,500 miles so far.

Since you are under the BtB warranty, why not ask the dealer these questions. They work on these vehicles every day.

Re: GMC Terrain 2017 SLI

the steam--- is it coming off the radiator/grille area?

If not-- and it is falling on the engine from the top- hood area.
it could be a misaligned seal on the hoot (back by the wipers).

Some years ago, there was a Service bulletin on the Trailblazers- for a seal allowing water to get past- and it was dripping onto the top of the engine- and making its way to one of the coils/spark plugs-- over time- it caused misfires.

Re: GMC Terrain 2017 SLI

I plan on taking it back but need to wait for a day that is suitable, I am the only one that drives so everything is depended upon me.

I am not 100% sure if it was dripping onto the engine area, when I had the hood closed it looked like the exhaust was coming from the front of the car, but I know it was not exhaust just a idea of how much steam was coming from it.

I am just seeing if anyone else might have come across or seen the same issues as I am having with a new car.

Re: GMC Terrain 2017 SLI

the other thing it may be--
is water that has landed on the AC condenser.
If AC comes on- the condenser (in front of the radiator) will heat up the water sitting on it- and cause steam.


The picture below-
I remote started in the morning, with AC ON- set to blow/defrost windshield.
I had washed the Traverse late in the afternoon- so water was still sitting on the condenser the next motning
But this is within a minute of remote starting- so the engine is still cold- and the radiator is nowhere near hot--- but the condenser has heated up enough to cause steam.

Others report seeing this amount of steam- when they come to a stop (think red lights) but water has recently hit the condenser... (freaks some people out- for sure!).

Re: GMC Terrain 2017 SLI

My vote is that this is the issue here, rbarrios. I think the last 3 or 4 vehicles I've owned do this on cool damp days or on cool days when I run the car through the power car wash. Your right, it does freak you out!

Re: GMC Terrain 2017 SLI

Thanks for the info the picture I got looks very similar, just was windy and raining. I have seen it do the same on dry cold days well I should say "day" it was not windy so it looked to have come from the engine seeping through the hood of the car.
I have never experienced this with any of my cars/trucks so it scared the **** out of me.

I hear this too, on my wife's '16, when I turn the wheel lock to lock it will thunk. Other than feeling cheap, I don't believe there's anything wrong; just the nature of a very light steering wheel.

Re: GMC Terrain 2017 SLI

Both our 2014 and 17 V6 Terrains had/have quite a bit of noise when turning the steering wheel when stopped and at low speeds. This is a hydraulic unit. I suspect low system pressure designed to give a little boost to gas mileage. Don't really like hearing it but doesn't seem to hurt anything.
