2017 Subaru Forester: sudden loss of power

Filed Nov 2, 2021 · Transmission · DE

Making a sharp turn going slightly uphill from a full stop, the car moves forward enough to enter the intersection and then there is no throttle response. The car does not respond at all to the accelerator peddle. The engine does not stall but rpm drop to idle speed. After a few seconds, throttle response returns. Very dangerous as you move onto a highway because the car lingers in the intersection while the car behaves as if it has totally lost power. This has happened repeatedly but at random times.

The vehicle was traveling along the highway at around 65-75mph and we went up a grade (cuesta grade) along 101 freeway in california and vehicle had a sudden loss in power while climbing up the hill. Ultimately, no power was ever regained and the vehicle shut off completely and stopped. We were stuck on the side of the road and had to call 911 to have a chp offer park behind us so that we would not be hit because we were partially in the lane. The car could not move so we had to have it towed to a subaru dealership. We received a check engine light, vehicle emissions controls, hill assist, and the car was shaking. Subaru recently made a recall on models that have had a loss of power but my vehicle is not on the list but I did experience everything mentioned in the recall. Can you assist?

On three separate occasions thus far, while driving approximately 70 MPH on interstate 93 in massachusetts and new hampshire, my 2017 subaru forester touring (with 21k miles) lost power and completely shutdown. All three times, I was luckily able to steer the vehicle to safety while avoiding other motor vehicles and neither myself, my passengers nor anyone else around us was hurt. When the vehicle decides to shutdown, it feels like the car drops itself into neutral, the rpms shoot up to about 4500-5000 and all of the lights on the dashboard light up. There is about a five second window to steer the vehicle to safety from when you first detect that the issue is occurring. After waiting for about 45 minutes after the incident, I am able to start the car back up and drive it. This is a serious safety concern of mine (and it is terrifying when it happens) and I have already contacted subaru of america asking for a solution. I am now currently only using the car on short trips and if I have to get on the highway, I stick to the right lane and do not go over 60 MPH.

Driving in the freeway around 20-30mph, some traffic. On the way to dropping daughters off to school. On the freeway switched lanes then car lost power and decelerated on its own quickly from 20mph to about 1mph, pressing the didn't do anything. Almost got hit by the rear driver behind me. Managed to move to right lane. Pressing the gas pedal did nothing, several lights on the dashboard appeared which included check engine light, traction control, oil light. Turned off the car to find the number for towing about 15 minutes later turned on the car and this time pressing the gas pedal made the car go, dashboard lights still on. Took the car directly to the dealership. Dealer claimed it was a bad cell on the battery that caused the problem, and also reprogrammed the computer. Bad cell on battery will not cause this to happen. Dealer also failed to write the details of the incident. Initial paperwork stated check engine light. Advice dealer to properly document incident.

On april 22, 2018, my 2017 forester with 22,000 miles on it stalled in the carpool lane of a busy la freeway (the 405 southbound near lax) at 4:20 p.m. Traffic in the lane had come to a complete stop and when it picked up again, the engine stalled. I immediately called 911. Chp arrived 20 minutes later and pushed me to the side of the road. A tow truck then towed my vehicle 47 miles to irvine subaru where the following day I was advised that their mechanics found nothing wrong with the car in spite of the loss of power which jeopardized my safety and that of my passenger. It should be mentioned that when this event occurred, my low fuel light had not alerted me to the fact that my fuel level was low; my on-board computer indicated I still had 80 miles until empty and the fuel gauge displayed one bar. In addition, I can state with 100% certainty that my tank was not empty as the tow truck driver was able to restart the engine and in fact drove it up on the flatbed of his truck when he loaded it there. As a result of this incident, I have lost faith in the safety of my vehicle and am leery of driving it long distances from home; a result that is unacceptable to me given that this vehicle is only a year-and-a-half old. The only photo I have is one of my vehicle loaded on the tow truck at the time of towing.
