What owners wrote

I was driving on the highway and it was raining. I lost control of the vehicle, the steering wheel was spinning uncontrollably. I was advised I most likely hydroplaned. The vehicle finally slowed down and backed into a guardrail. Only the rim of the driver side back tire was damaged. The impact felt like the impact felt when hitting a curb too hard.

Reported at 28,000 miles, November 2020 Crash

Situation: driving uphill on hwy 120 on new priest road, big oak flat, ca, two lane mountain road. Slow car in front of me and a delivery truck tailgating. Slow car eventually moves aside in a turnout and I accelerate to open up space between myself and what I thought would be the truck but somehow the slow car returned to the driving lane ahead of the truck.
