I was driving on I-20 with cruise control on @ 71 mph (night time) @ 7 min into using cruise control, the suv acted like it stopped for a quick second (scaring me) I remember rubbing my neck afterwards, thinking it was almost like whiplash. I pulled off the road into parking lot. I thought maybe I had a flat or tire issue, no tire issues. I then stopped @ a store, when getting back into the suv, I could smell something awful. Like something had burnt. Still don’t know. I have not used the cruise control since this incident. It was Xmas weekend, so I have to wait till dealer opens back up to have it checked out.
I was unable to stop my vehicle from accelerating. The brakes were engaging but my vehicle continued to build speed. Myself and my family, as well as others on the road, were all put at risk due to my vehicle not responding or failing to control speed; cruise control was not engaged. My insurance company, USAA, is currently investigating and determining total damage estimate. No warning lamps, indicators, or messages were presented prior to collision. The rotors and brakes were glowing red after collision from continuous attempts to stop the vehicle.
KNOWN ISSUE: Chevy Traverse owners may experience a condition wherein the front exhaust pipe on their crossover separates from the mounting bracket, resulting in damage to the pipe. Now, General Motors has issued new Special Coverage that addresses this issue. NEW ISSUE: Rear exhaust pipe is also affected. When separated/cracked this was leaking carbon monoxide fumes into the inside of the vehicle when driven. Our family's safety was put at risk breathing these fumes. The Chevrolet dealership says that only the front exhaust issue is being recalled/covered but rear is not even when it is attached to same mounting bracket with known issue. Appeared/noticed as loud muffler sound and strong smells of fumes.

Occasionally when putting the SUV in reverse, the car does not go into gear. I'll hit the gas and nothing and then all of the sudden it goes into gear. It's almost like it's in a delay sometimes I'll have to put into drive and then reverse for it to go into gear.
