Purchased from Carvana. Nine days after purchase came out to a dead battery took it to the authorized dealer and they said the battery was a bad cell battery. Replace the battery. Six days after they replaced the battery it was dead again. This time they had it in the shop for two weeks before they found the issue. It had been aftermarket wired with a GPS tracking system that was draining the battery. They said if I have any further issues with it, I need to take it to a dealer. They gave me a bag full of multiple components that had been added to the vehicle. I do not know how Carvana missed them all.
Having trouble with leaks and the evap purge system. I repaired it three times. The vehicle will turn off while driving.
There was an instance a couple months ago where I was driving and my ignition stopped. To my luck, I was in a safe area to stop but it is dangerous for this to be happening with my car while I am driving.
