Collision sensor on Vehicle has started going off randomly and so do the breaks

Asked by Sep 03, 2014 at 03:23 PM about the 2014 GMC Terrain SLT1 AWD

Question type: Maintenance & Repair

My 2014 Terrain started having issues with the Collision Sensor going of when I am just driving down the road at speeds of 25-50. When the sensor goes off I can feel the break at the same time. I am always just driving, not breaking or turning or anything. GMC dealer cannot find anything wrong. brought it back home and 3 days later happened again. Weather type is not a factor. Anyone else have this issue

Take it back as it is under warranty. The computer sensor is acting up.

The car manual states the sensor does not activate unless your going 35 MPH. You can change the distance you get to the car in front of you before the warring is activated on the steering wheel control. I was told my car (2014 I-4) has a automatic braking system to slow you down when going down hills, but I was not told it works on the collision warring device. The automatic braking system uses the engine to keep the speed in control, much like trucks use the engine to slow down without using the brakes so they will not heat up.

I now have to modify my above answer. My Terrain does activate a braking sensor if the car in front of me slows down quickly and I don't. I am a non courteous driver and will get as close to the car as I safely can. I notice it does it at times even when there is no car in my lane, but I'm overtaking cars in other lanes. It's a pain, but it does warn me to lookout for other cars. Guess we will just have to get use to it.
