2023 Subaru Ascent Other Problems

Your vehicle rolled backward while parked on May 12, 2024, even though it was in Park. The door struck you as the car moved, and it rolled over your leg, causing injuries to your lower leg, ankle, and foot. You haven't been able to reproduce the problem since, and the dealer says they're not aware of any similar issues. A thorough inspection of the parking brake system and transmission shift mechanism may be needed to identify why the vehicle moved.

Your passenger-side mirror has been missing since March 2025, and you ordered a replacement part in April that was supposed to arrive within weeks. As of July 2025, delivery has been delayed to August, leaving your car without critical visibility for safe driving. Getting the mirror replaced will involve installing the new mirror assembly once it arrives.

Your tires may be wearing out unusually fast due to damage that occurred during the tire mounting process at the factory. A misaligned part on the assembly equipment may have stressed the tire's inner structure, which could eventually cause the tire to fail suddenly and lose air pressure while driving. Subaru will replace all four tires for free, and you should contact your dealer to confirm if your vehicle is covered by this recall.

Your 2023 Ascent is getting 15-17 MPG in city driving, while the window sticker promised 20 MPG city and 22 MPG combined. Even on a highway trip, you only achieved 20 MPG despite resetting the meter and filling up fresh. You're concerned that Subaru's fuel economy claims on the monroney label may be inaccurate, especially since achieving the advertised numbers seems to require unusually cautious driving habits like keeping RPMs under 2000 and avoiding normal acceleration.

I attempted to make a U-turn with the steering wheel fully turned to the left. When I accelerated, the car took off and went straight into the curb. It did so by “plowing” or what is referred to as severely undesteering - which forced the front right face of the wheel into the curb, breaking the wheel off. The vehicle continued accelerating for another 50 feet (as can be seen in the photographs) when the engine gradually and audibly died down and came to a stop. The brakes were no longer functioning properly at that time while sinking to the floor as they did immediately after the first impact. In the four months and 2300 miles that I’ve been driving that car, I’ve noticed surging a number of times during warm up and also while the CVT is “shifting.” I also constantly have to modulate the gas pedal to keep the vehicle at a consistent speed. RPMs drop and surge in an inconsistent manner. Also, when the wheel is turned completely to the left lock, (which is how my crash occurred) and upon acceleration, there is a bang/grinding sound from the front left axle. Lastly, I noticed at least one other incident where it seemed like the turbo would not disengage when lifting off the throttle. In other words, it lagged in response to the throttle by about two full seconds before the engine began decelerating.

Side passenger window spontaneously developed a crack about 10 inches long while sitting parked. The crack is located the direct line of sight of the side view mirror.
