Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“On sunday, the 22nd of march, I was traveling south on us hwy 45. The sky was clearing and the road was dry. I had my cruise set to 65 MPH. As I approached an overpass, the distance sensor on the front of the truck mistook the shadow of the overpass as a stopped vehicle. Warning lights and buzzers went off and the vehicle did a hard brake. Luckily, there were no other vehicles around me. I took it to our shop and the system was cleaned. Four days later, the sensor mistook an overhead interstate sign for a stopped vehicle. Again, the warning lights and buzzers and a hard brake. …”
