“Vehicle was stored in a closed garage prior to operation. I started the vehicle and began to back out of the garage into the driveway. After approximately 3-5 feet of movement backward, several yellow warning icons illuminated on the dashboard and the vehicle's brakes stopped functioning. The vehicle free-rolled several feet down the driveway. After about 1 second, the vehicle brakes engaged, all warning lights went out, and the vehicle began operating normally. I attempted to replicate the fault but was not able to. …”

“I was driving around 60-65 mph on the highway when suddenly a warning alarm went off and the warning light read “stop vehicle and check brake system”. I took my foot off the accelerator and car continued to maintain speed. The power brakes did not work. I put the car into neutral hoping that would slow it down, but it continued to maintain speed.

Starting the next day we noticed the car was weaving without any steering, but thought it might have been icy road conditions and waited to see if it reoccured. The car has since weaved intermittently, but has righted itself after releasing the accelerator. However, on 1/15/25 while traveling about 50mph, the car started weaving on its own and when the accelerator was released the car started to wildly fishtail. Called dealer and they agreed this was a serious issue and agreed to see car the next morning. …”
