While pulling up to a drive thru window the vehicle shuddered and the engine shut off. I lost all power steering and had to come to a stop, shift into park, then restart the engine. No check engine lights or warnings illuminated. There were no status messages to indicate what caused it to shut off. Also the driver side mirror shakes a lot, just like all the other reports say.

While cruising on a 2-lane road or a freeway, the vehicle will cross over the adjacent line, either left or right. This generally happens between 50 to 75 mph. The event happens either when cruise control is on or off. Wind is not necessarily the problem. The solution requires one to take the necessary immediate steering correction. At times, the departure from the lanes may repeat. This may be a temporary correction. This may create a head-on collision if not immediately correctly manually. VERY DISTURBING!

On 9-May, 2026, the vehicle was driven during the morning with no warning lights or indication of component failure. Vehicle was parked on the owner's driveway at approximately 13:00. Approximately 15:40 I started the Ascent’s engine, let it idle for about 60 seconds, buckled up and scanned dashboard and rearview mirror. No warning lights or any fault indication. Approximately 15:42, I put the vehicle in reverse and released the brake Approximately 15:42:30 the vehicle exited the driveway Approximately 15:43 there was a shudder on [XXX] (heading north); the dash lit up with multiple warning lights; the check engine warning illuminated and the ATOIL Temp warning light engaged. At this time, the vehicle rolled down a hill, un-commanded, and only with repeated pumping of the brake did the vehicle stop. Approximately 15:49 I was able to park the vehicle, engaging the hazard flashers and exited the vehicle. While no one was injured in this instance, had this happened on a highway there would have been insurance losses and potential injuries.

The hood acts like it is going to come loose whenever I : 1> Meet a semi-truck on a two lane road. 2> If following a truck on interstate. 3> Driving when windy. The flex in hood is very unnerving for fear it is going to blow off when in traffic. The body shop has adjusted latch today but did not correct the issue.
