2017 Subaru Crosstrek: engine stalls while driving

Filed Nov 7, 2026 · Electrical, Fuel system · PA

While driving, the car stalls out. Sometimes it recovers automatically, but most times I need to restart it, causing me to be very concerned about a possible rear-end crash. I have taken it to the dealer (Rafferty in Newtown Sq PA) twice. The fist time (Oct 8th) the MAF sensor was replaced and a fuel induction service was performed. The problem seemed to be fixed for about a month and it recurred. The second visit (Nov 6th), the technician wanted to perform a fuel induction again until I reminded him he had already done that. He did replace a clamp on the loose intake hose. Upon return, I looked up the problem online and found some possible solutions that weren't offered, like: 1. Ignition coil ECM short circuit 2. CVT Torque converter lockup solenoid 3. Crankshaft position sensor (perhaps that is the MAF sensor that was replaced) I have opened a case with Subaru (Case #261107-1500076) and am waiting to be contacted by a Field Tech Specialist.

*The engine experienced a failure of an internal valve spring, a component that controls the operation of the engine valves. The failure required significant engine repair, including engine teardown. The vehicle was diagnosed by Subaru of Olathe, and the failed component and vehicle should be available for inspection through the servicing dealership. Subaru of America reviewed the dealer's repair estimate and approved partial goodwill assistance toward the repair. *A valve spring failure is a serious engine malfunction that can result in engine performance issues, loss of power, engine stalling, or engine damage while driving. Such a failure has the potential to create a safety hazard if it occurs during vehicle operation, particularly at highway speeds or in traffic. Subaru has previously acknowledged valve spring failures in certain vehicles through Recall WTY-84 involving engine valve spring fractures that could lead to engine malfunction or stalling. *Yes. The failure was diagnosed and confirmed by Subaru of Olathe, which provided a repair estimate totaling several thousand dollars and recommended repair of the valve spring failure. Subaru of America relied on the dealer's diagnosis when approving goodwill assistance toward the repair costs. *The vehicle was inspected by Subaru of Olathe and the diagnosis was reviewed by the [XXX] Customer Advocacy team at Subaru of America as part of a goodwill assistance request. There is no indication that the vehicle was inspected by police, insurance representatives, or other third parties. *Vehicle started stalling at lights and jerking when in motion, seemed to have no power available and dangerous and appeared suddenly in Sept. of 2026. *Vehicle is a 2017 Subaru Crosstrek with approximately 72,000 miles. It was purchased new and maintained primarily through Subaru dealerships. The owner believes a valve spring is not a wear-and-tear item and should reasonably last the life of the engine.

On Sunday, 5/9, my wife and I were traveling back from NY to Philadelphia when out of nowhere, my car stopped accelerating and stalled, completely, in the left lane on the Staten Island Expressway. I called 911 and they were able to dispatch a tow, immediately. The battery worked. The dashboard said to check the engine. Luckily, the tow arrived in about 5-10 minutes. The driver escorted us out to his truck and protected us from oncoming traffic. We were brought to a safe location and were able to start the car (and it kept running), without any assistance. We were too afraid to continue the ride back to Philadelphia (lots more distance and highways to go). We called AAA to tow the vehicle to my Subaru dealership in PA. This has never happened before. One strange thing that has been happening over the last few months is that sometimes our key will get stuck in the ignition when we try to turn the car off. We are able to turn off the battery, but are unable to turn the key further. We have to try several times or even put the car in drive and then park before trying to turn it off again. I am not sure if this is connected. The service at my dealership has been very nice. They’ve had my car for over a week. Unfortunately, they haven’t found anything wrong. They’ve checked for codes and nothing’s come up to indicate any issues. I am really at a loss because I do not feel safe driving this vehicle. I did see that there is a new recall (https://www.consumerreports.org/car-recalls-defects/subaru-recalls-crosstrek-forester-impreza-for-safety-concerns/) but it does not include my particular year. I wonder if this problem actually involves 2017 Crosstreks. I do not feel safe driving my car.

Car stalls randomly upon acceleration from a stoplight or stop sign. Takes 3 to 4 seconds til the car accelerates. During all this time the engine is still running. Has happened 4 times within the past year. Afraid this may cause an accident, as yesterday I thought I was going to get t-boned. Will not drive my grandsons in this car.
