“I was making a left turn during a green light my car was in motion. A white van was speeding towards me from the drivers side going straight at me at high speed with a red light. They hit the front drivers end of my car which made my car spin out. The airbags did not deploy. The whole front end of my car was ruined.”
NHTSA complaint #11320468, filed 2020-04, 45,000 miles“Our new Terrain has vehicle in front visual warning systems. We were following a tanker type semi on the interstate and pulled all the way up behind the tanker semi (within 25 ft) and the vehicle in front light never came on. We tested this on all types of cars and trucks as well as standard box type semi and it worked perfectly. I have pictures of the rear end of the tanker semi in which it did not detect at all.”

When I spoke to service man at dealership, he stated that one fob was faulty and they would order a new one. I haven't heard back from them...today I got into a front end collision where the air bags did not deploy causing me injury. …”
