Owner report 11579772 · 2024-03-27 (March 27, 2024)
About five months ago, while driving on the highway, the care would say it's in Drive, but sounded like it couldn't get out of 1st gear and I'd get high RPMs. Thankfully there was stop-and-go traffic and I didn't have to exit pull off the highway or hit high speeds. I exited at the next exit and, as soon as the car stopped, it wasn't possible to get it into gear. Eventually the car started and I was able to get into gear and drive it using Manual drive mode. Once at the dealership we were told it was a bad VCR and they needed to replace tha…

Owner report 11556569 · 2023-11-23 (November 23, 2023)
There is a continuous issues with my battery dying. There are multiple malfunction lights showing, particularly the rear collision light. The check engine light is also showing, and I have had an oil change recently. The car breaks on its own. While backing into a space, the steering wheel would not completely turn right until I straightened up the car. Finally. I have had my driver's side car seat repaired three times by the dealership. It works sometimes and not others. Any suggestions on any or all of this would be helpful. Thank you.
