While driving on a rural road the 'collision warning system' activated with no vehicles in sight either in front of me or in the opposing lane. It happened again approximately 3 miles later. I turned the system off. This has the potential of a disastrous out come if I would have been in heavy traffic.

Driving between 40-45mgh and stabilitrak failure service and ABS failure light comes on. At every bump the service lights goes on and off. Then on a smooth service the stabilitrak lights comes on until I get home. With the collision warning turned on the car also and almost frequently tends to brake on its own while driving. But here's the real problem this 2014 gmc terrain denali car is not on the 'recall' list - why? Seems it's from the same car manufacturer with same issues, shouldn't it be on the same recall list.

1) brakes have always rubbed & grabbed really hard when applied. Almost like they are defective rotors. Hard to stop fast. I notice they recalled a lot of their brakes, but not mine. 2). Transmission jerks & shifts very violently @ 16 & 17 miles per hour. Seems to slip & not shift @ that speed really rough. Has always done this. 3) sometimes the collision alert goes off & there is nothing around I live in the country & have no traffic it will just go off scares the crap out of you & startles me. I saw another person had this happen also all situations are in motion while driving. Biggest concerns are the transmission & brakes. 4) okay seats are supposed to be leather however, they went cheapy on the sides. It cracked & continues to crack & tear because the sides are vinyl. This started to happen @ approximately 3,000 miles. I only have 32,000 miles on it. I don't drive much.

My car makes a rubbing noise when and only when you stop. Also my forward collision alert comes on when nothing is in front of me. Sometimes it won't even come on when a car is in front of me.
