Vehicle has an issue where it intermittently throws errors, loses power, accelerates on its own, and is difficult to steer. I purchased it with 12,800 miles in it and it has been having this issue since then and no one has been able to fix it. It appears from maintenance records it has been happening since it had 2800 miles on it. It has happened many times with me since I purchased the vehicle in November of 2023.

THE ENGINE STOPPED ITSELF WHEN I WAS AT A COMPLETE STOP AT A TRAFFIC SIGNAL. AFTER A FEW MINUTES I WAS ABLE TO START THE ENGINE AGAIN. IT DID THIS THREE TIMES IN THE SPACE OF AN HOUR. ALWAYS AT A COMPLETE STOP.
