Electrical system

“I purchased a Subaru for reliability and safety reasons. This car has placed my family in some dangerous situations. Every time the outside temp is 90+ degrees F and it is driven on a road trip of 200+ miles, the car's acceleration shuts off. There is never any warning or check engine/trans lights until after this happens. Nate Wade Subaru in Salt Lake City cannot find any codes and does not know how to help. The car will not restart after being turned off, even after waiting up to an hour. We have had to tow it. The last incident taking place 7/30/2022 with our 19 year old son driving. The worst part is that twice it happened in the far left lane with no option to get over to the right side of the highway safely due to traffic. Cars/trucks from behind have narrowly missed hitting us because there was not enough shoulder to pull out of the way. This has happened both in UT and ID where posted speed limits were 70-80 mph and put us in real danger. I don't know what to do other than sell the car. But I don't feel right doing that without sharing this problem -which would then "kill" the sale. It is unacceptable to not have a fix for this issue or at least a…”

Power train

12 reports
“My transmission completely locked up on me while driving at interstate speeds. I was traveling at 65 MPH with the car in regular driving mode, on cruise control and the transmission completely locked up on me. The front tires locked briefly, causing me to go into a small skid, which I was able to correct, and then the engine revved high and I had no power. This lockup and skid caused a rapid deceleration of the vehicle and had there been lots of traffic around me it would have caused a major accident on the interstate, possibly causing fatalities. My transmission completely locked up once I went through the nearest intersection to get to a side road. This left me stranded in the middle of a major highway intersection with no ability to physically push my vehicle out of the way. The vehicle behind me just about rear-ended me. This has been a major issue with these transmissions and a major safety issue. These transmissions should be put on a recall since this is a major safety issue. The extended warranty that Subaru has put out only waits for a problem to occur, this does not save lives but only puts them in danger. They should be FORCED to do a recall. No…”

“All of a sudden, with no reason whatsoever, my daughter's car has "rod knock" with less than 100,000 miles on it. Bought this Subaru for my daughter so she would have a car that would last a long time and she would be safe. Maintenance was kept up at our local mechanic religiously. I am saddened and disappointed in the mechanical performance of this vehicle. Started with lights going out early in ownership when it was new, and now this. I have a Subaru Impreza as well and am strongly considering trading it in for a Honda. I have family that works for Subaru and I wanted to support family and bought 2 Impreza's based on belief that your brand was highly regarded for longevity and safety. Engine's in vehicles should last more than 100k miles, regardless of the manufacturer. This should be a recall based on internet research. My ask is that Subaru stands up to its marketing and its product and takes care of this repair at no cost.”

Vehicle speed control

7 reports3 crashes
“The contact owns a 2015 Subaru Impreza. The contact stated that while reversing the vehicle at 10 MPH, the transmission was shifted into drive (D), and the vehicle experienced unintended acceleration at 30 MPH. The contact depressed the brake pedal, but the vehicle failed to stop and instead accelerated. No warning light was illuminated. The vehicle then crashed into a building. No air bags were deployed. The contact did not sustain any injuries, but medical attention was received on the scene. A police report was filed. The vehicle was towed to a repair shop and had not yet been deemed totaled by the insurance company. The contact stated that a police officer later arrived at the residence to deliver a notice suspending her driver's license indefinitely due to a medical condition. The manufacturer was not made aware of the failure. The failure mileage was approximately 63,000.”

Air bags

7 reports1 crash
“We bought our 2015 Subaru Impreza from a used car dealer (we are second owner) in February 2020 with 55K miles on it. On our test drive, we noticed the air bag said it was off even with a passenger in the car. We agreed to purchase the vehicle upon repair. It was repaired and the mechanic guaranteed his work, and we had no issues for a year. Then, we moved across the country and the sensor began to sometimes malfunction again. The Subaru dealership quoted something like $3k to fix it. In Googling the issue, I see Subaru has had this issue in previous models. Please open an investigation to see if the problem continues in more recent years.”

Steering

7 reports
“Power Steering failed, extremely hard to turn steering wheel, EPS Light on dash illuminated. Luckily happened in driveway. Thinking back steering seemed odd last week was less effort to turn left as opposed to turning right.”
