2021 Subaru Crosstrek Electrical system Problems

“Was driving on highway when all of the lights on my dash illuminated. Eventually I got a warning for oil at temp alarm. Was giving code P2757 and P0700. Looks like this a common issue in Subarus but doesn’t look like it covers anything after 2020.”

“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”. …”

“There have been multiple instances where my car has failed to “restart” if the auto-start-stop feature is on. I immediately turn that setting off every time I get into my car because if I pause for too long at a light/stop sign etc.the engine will stall and turn off (without being in park). I have reported this to Subaru on many occasions and they’ve told me to replace the battery, so I did, and nothing changed. I’ve also replaced the starter and that didn’t help either. I’m now unable to turn my car off at gas stations because I’m worried it won’t restart. …”

“Purchased in August 2024, had to get a new battery 2 days after purchase & then went to the dealership January 2025 because my battery kept dying & I was stranded at the airport late night. They acknowledged is has a parasitic draw but did not notate the source. They claimed I needed a new battery when my previous Subaru branded battery was only 5 months old. The new battery was almost $600 which is double/ triple a store branded equivalent. I purchased yet another battery but non-Subaru branded since theirs did not last even 6 months. Still have been experiencing the same issue. …”

“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. …”
