“On two incidents randomly and without warning the car failed to accelerate while driving in traffic on an open road and I had to coast to safety and put in park, then drive, then travel less than five miles home. Both times I immediately scheduled service with suburu with appointments about a week out. The car drove without incident while awaiting service. Service failed to replicate the problem, diagnose or remedy it after having the car a week and I was told“vehicle is operating properly at that time”. …”
NHTSA complaint #11603340, filed 2024-07“I was crossing two lanes of a very busy ocean front street when the engine “bogged down” . I let off on the gas pedal and then depressed it again, which then caused the engine to go off. I the quickly restarted the engine and was able to get out of the way of oncoming traffic. This was the only time the engine failed, but on about three or four previous times, the engine “bogged down” when I depressed the gas pedal, but recovered after I quickly depressed the pedal again.”
NHTSA complaint #11431202, filed 2021-08“I was driving my 2021 Subaru Crosstrek slowly in a parking lot when it unexpectedly accelerated on its own without me pressing the gas pedal. I believe the Crosstrek was now going 40mph. I tried to shut off the engine and brake at the same time but neither one had any effect. I thought maybe I had two options. Either hit another vehicle or pedestrian or turn my car into the curb. I decided to turn into the curb which resulted in the breaking of both axels, flattening all the tires, and sustaining damage to the front fender and headlight. …”
