The 2021 Subaru Forester had been functioning normally with no warning lights. About 25 minutes into the drive I had come to a stop light on an upward incline. When the light turned green I moved from the brake to the gas as usual. However the auto-start function on the car failed, causing the engine to stall. A loud clunking sound was heard and the dashboard lit up with multiple lights, although I do no recall which ones were illumined. I attempted to press the gas again and the car did not respond. During this short time my foot was pressing on the gas the car rolled backwards and collided with the vehicle behind me. I continued attempting to press the gas pedal and still no acceleration was made. After parking and restarting the car it has resumed normal function. I have not yet visited the dealership so this issue has not yet been reproduced, nor has the offending system been inspected. I'm summary, the automatic engine start failed at a critical location, putting myself and others in serious danger and ultimately caused a crash.

Engine stalled 2x within 8 days at major intersections (both times), therefore blocking a lane in the intersections. Was told 1st time it was a gliche by dealership. Upon researching prior recalls for this make and model, engine stalls have been an issue. Dealership still can’t figure out issue.

On 08/23/2022 while driving on a four lane city street, light rain, moderate traffic, at about 35 mph, the car suddenly lost forward speed, depresssing the accelerator move rpm to over 3000, with continued loss of forward speed, until suddenly the drive train engaged and forward speed resumed. This is the fourth time this type of event has occured. A check at a Subaru dealer the next day revealed no codes in memory. Fortunately there was no heavy traffic on this road at the time because in another half hour there would have been very heavy traffic. This is very disconcerting and potentially dangerous to vehicles directly behind. Is there a problem with the Eye Sight system that triggers a sudden loss of speed when there is no vehicle close ahead?

on 7/9/22 @ 6:00p I was with my wife & 2 grandsons going into a diner parking lot. as I was slowly going into a spot the car suddenly and without warning accelerated causing the car to drive over a cement parking stop, over a 1foot high cement wall, through a chain linked fence which had privacy covering, down into a 12 deep ravine. after shutting off the car my grandsons, wife & myself had to crawl out through the rear hatch. when things quieted down we realized that none of the safety features were activated (anti-collision warning, anti-collision braking) I thank God no one was hurt. Subaru needs to look into this so in the future no one ever experiences this.

This is in reference to tracking # 11462054, a third incident of sudden engine power loss/deceleration. On 04/27/2022 the 2021 Subaru Premium was returned to the selling Subaru dealer to try and fix the two previously reported problems . They found no codes in memory and no problems when road tested. I left the dealer to return home, and about 10 min. after, on a two lane city street, the engine suddenly lost power while I was going about 25mph, and decelerated to about 10mph before regaining power. I drove back to the dealer and a service rep came with me for a road test of several miles, where the car operated normally. At the dealer, there was no code in memory. The mileage was about 13,135. No paperwork was provided by the dealer. How to resolve this problem???
