I was driving with cruise control going around 70 when the car started slowing down suddenly. Not wanting to slow down even more, I turned off the cruise control by hand using the cancel button on the steering wheel (rather than tap the brake) but when I then hit the accelerator, the engine felt like it was in neutral, revving past 6000 rpm on the tachometer. At that point, I realized I had no control over the drive train so I pulled off the road onto the center median of the highway, just as the engine died - fortunately, there wasn’t anyone following close behind. We had been driving for about 1.5 hours with the AC blasting and the gas tank at that point was low, with less than 1/8 remaining. All this happened without any dashboard warning lights turning on. This was the very last leg of a ten-day, 2,000 mile road trip. I tried restarting the engine but only got clicking. Since I thought we’d be struck a while and it was so hot, I turned the key to the accessory position and was able to roll down the windows. We sat there for a couple of minutes wondering what to do. It took another minute to find my AAA card. Before calling for roadside assistance, I tried starting the engine again and this time it turned over. We did not have any further problems in the remaining 100 miles of our trip (though I was very anxious about it happening again). I took the car in to a Subaru service center this morning (36 hours later). They did a multi-point inspection and road test but did not find any issues and were not able to replicate the problem.
2015 Subaru Forester acceleration complaints
Page 2 of 3: complaints 11 to 40 of 70, newest first, as owners wrote them.
I have had several instances while driving on the highway when my forester revs to a very high RPM, the vehicle speeds up suddenly, and then shuts off completely. The only fix is to put the vehicle in neutral, move to the shoulder, and restart the vehicle. This has happened approximately 4 times during my 1 year of ownership and it is completely random when it occurs.
The contact owns a 2015 Subaru Forester. The contact stated that while driving approximately 35 MPH, the vehicle experienced unintended acceleration causing the driver to immediately depress the brake pedal to abruptly stop the vehicle. After the failure, the vehicle operated as normal. The cause of the failure was not yet determined. The manufacturer and local dealer were not yet notified of the failure. The approximate failure mileage was 72,000.
Sudden accelerations.
The contact owned a 2015 Subaru Forester. The contact stated that while driving at an undisclosed speed, pulling into a parking space, and while attempting to park the vehicle on the street, the vehicle experienced unintended acceleration. The contact had to depress the brake pedal several times before the brakes were engaged. The failure occurred on two separate occasions. The vehicle was taken to the dealer, but the dealer could not replicate the failure. The vehicle was not repaired and was later sold to St. Cloud Subaru (141 Park Ave S, St. Cloud, MN 56301). The manufacturer was not made aware of the failure. The failure mileage was approximately under 60,000.
This 2015 Subaru accelerates without warning and without gas pedal input. The issue arose about a month ago (July 2021) and has persisted ever since. The vehicle will rev while in park and once put into drive will jolt aggressively and without warning. Additionally, the vehicle will enter low-power mode at random and decelerate to 15-20mph. This has caused multiple hazards when driving on highways/interstates where pulling over is difficult or impossible.
The 2015 Subaru Forester accelerated unexpectedly while slowly turning into a a Walgreens parking lot. The acceleration could not be stopped by stepping on the brake, and the car crashed into the brick building. The vehicle is at Phil's Auto Body Shop in Rosemount, MN. The estimate on the car is complete, and waiting on State Farm insurance to approve. The police were at the scene of the accident. Walgreens has video of the accident from their security cameras.
Auto accelerated unexpectedly after leaving car wash bay. Auto sped through parking lot into street and crashed into another auto traveling on a road.
Suddenly it started to accurate and the other was all in bord control system default are lighting up
Tl* the contact owns a 2015 subaru forester. The contact stated that while driving, the vehicle experienced an unintended acceleration, causing the speed to increase to approximately 62 MPH after leaving from a stop light. On another occasion while driving, the failure recurred and the driver downshifted to slow the vehicle which caused damage to the transmission. The cause of the failure was not yet determined. The local dealer austin subaru located at 8100 burnet rd, austin, tx 78757 and the manufacturer were notified of the failure. The failure mileage was 134,000.
I have experienced unintended acceleration during my ownership of my 2015 subaru forester xt while I was stopped on a city street. There is also a "lunging" feeling whenever you press the acceleration of the vehicle after proceeding from a complete stop.
On 3 separate occasions, my car has shutdown on the highway at speeds around 75-80 MPH. They all happened during road trips while my car was between 1/8 and 1/4 tank. The car has a noticeable drop in power, which feels like the transmission disengages and applying more gas doesn't help. This is incredibly dangerous!!!! Luckily I was in the middle of nowhere on all 3 locations so I was able to pull over without incident. The car will not start, until more gas is put in the car. It's not out of fuel though because I tracked how much gas is in the car and how much I filled up after towing. This only happens after driving for multiple hours. I can run the car to empty if I'm just driving around town. A recall needs to be issued for this issue. I can see there have been tons of complaints around this issue.
Eyesight system fails regularly or does not work at all. This impacts all proximity warnings, automatic speed control and wheel slip control.
Car in motion. Happens on a stop, parking the vehicle in progress, driving slow. When pushing gas pedal slowly from start point; vehacle speed up so much that I have to press brakes pedal to hold the speed down. Happens once every other time.
While driving on the highway at 65mph the car lost all power. The rpms went up like it was in neutral (car was still in drive). Fuel tank was down to a little less than 1/4th of a tank but still had 100 miles until empty. Adaptive cruise was engaged at the time (automated cruise applied accelerator that rose the rpms to 4500). This was in the middle of a 4 hour road trip on a flat straight road. Car exhibited no warning or lights until complete power was lost. I was able to safely pull over to the shoulder. All lights came on in the dash after I was stopped. I turned the car off and I was able to immediately start it again. Shortly after I filled up the tank and the car drove fine for the next hour until I was home. This was a scary incident that could be very dangerous. I noticed that this car has about a dozen other reports that are much like this in the past year.
This is an intermittent problem. The vehicle surges sometimes and misfires when it cold starts. I took the car to the retailer, they did not found any issue. Only the differential oil was changed. They told me to return if the problem occurs again. Again it came back and intermittent. I am sure retailer will not be able to find the problem again. It is sudden loss of powers for couple seconds and it a hazard on the road. Hope there are recalls on this issue.
While driving in the highway at 75 MPH with cruise control on the car suddenly went to 5000 RPM and at the same time started to brake all the lights in the dashboard came on I pulled over and the car's engine shut down. I tried to started about 5 06 times the car wouldn't star and after that the car was completely dead. I had it tow to a shop. The next morning it started like nothing the mechanic at the shop said it was the battery.after changing the battery I took it to the gas station after putting gas it wouldn't start again after several tries it started.at this point I don't think the battery was the issue but I am glad I got home. This happened in starkville ms 200 miles from where I live.
I drove into garage at about 1 m.p.h. And put the car in park. After idling for about 3 seconds the engine accelerated to 2,800 r.p.m. And stayed there,I couldn't get it to slow down. I pressed on the accelerator many times,it wouldn't slow down or speed up. It just stayed at the same speed. Pressing the brake pedal didn't do anything. I got it stopped by turning off the ignition. When this happened the check engine light came on. I got code p2138. I am replacing the accelerator pedal position sensor as I am afraid to drive it.the car is exactly 5 years old,I bought it new. It has 16,552 miles on it now. I was very lucky it was in park when it did this. I hope the new part fixes it.after 4 restarts the check engine light went out. I took it for a short drive,and the engine kept wanting to run fast. Two days later it seems ok,it slows down now.
We were driving in the freeway at 65mph, we had been driving about an hour, on the freeway with some traffic but mostly moving normally. Suddenly with no warning nor engine lights, the car reved but didn't respond to the gas pedal. As though it had run out of gas. The low fuel light had gone on already, it turns on around 70 miles to empty, but we still had 50 miles to empty. We pulled over and called roadside assistance to deliver gas since that's all we could figure had happened. After about 30 minutes waiting we decided to try it and just see if it would start and it did! We drove to the next exit and got gas with no further problems, and continued on home after. This was very scary and left my family sitting stranded on the side of the freeway. No engine lights, no codes, nothing obvious to fix. Now I'm nervous to drive with my kids in the car in case it happens again.
Twice while driving on the interstate on a 3-4 hour trip going approximately 70 MPH using cruise control with approximately 1/12 - 1/6 tank of gas, my engine began to rev and at the same time lost power and speed. The first time I pulled off the road, shut the engine off, waited approximately 10 minutes and was able to restart the engine and finish my trip. It happened the second time with mostly identical circumstances. I pulled off the road, turned off the engine, waited and was unable to start the engine. I had to tow my vehicle to a dealership. They ran diagnostics with nothing turning up. They were however able to start the car when they tried. This was extremely dangerous being in 70 MPH traffic and having no speed control. I have the dealership paperwork from the service. Now the engine does not seem to have the normal power it usually does when accelerating. *tt
On 2 separate occasions was driving my 2015 subaru forester (touring edition) at highway speed, 70 MPH, the car lost power and started decelerating. Luckily both times I was able to get over to the shoulder. The car re-started after awhile. The first time the low fuel light was on but I had over 50 miles left according to fuel sensor. The second time, a month or so later, no low fuel light was on. There were 2 bars left on the fuel gauge. Again car totally decelerated and then a few minutes later was able to be driven. Subaru dealership claims they have not heard of this problem but someone did call them about it the day before I called. I am scheduling an appointment where they say they will do a diagnostic on it. I am seeing multiple complaints on this exact car on carcomplaints.com this is an extremely dangerous problem and subaru should not be waiting for fatalities to happen before recalling these cars.
When stopped in traffic car hesitates, stalls and stumbles to accelerate for a few seconds. Unable to shift from 1st to 2nd smoothly (stuck in 1st gear?). Was rear ended when unable to accelerate at light. Dealer did software update that did not fix problem, still ongoing
In heavy traffic my speed control failed. The engine rpms went down by themselves while I was driving on freeway. The gas pedal completely unresponsive.
When using light acceleration such as in a parking lot or at a red light or stop sign to start going the vehicle bucks forward it will literally make you jerk back in the seat. Also while pulling onto a street it jerks forward but has hesitation which isnt to safe if you ask me when trying to get out on the road if cars are coming...
When highway driving multiple warning lights are illuminated on dash, traction control, eyesight, cruise control off, hill assist. The eyesight systems are disabled shutting off cruise control. When this happens the rear brakes light are not working. When the car is the shut off then restarted and the brake is depressed the car will not come out of park after starting. This happens when it is reset after the car sits off overnight. The last time I could not get it out of the park I went behind the brake pedal and move the brake switch and pressed the connection on top in. This reset the system and I was able to get the car out of park and all the warning light on the dash disappeared. The stoplight switch/brake switch part #83311fj001 is defective. On 3/1/19 subaru announced a recall not sure if it's this part/issues but I am hoping it is.
Tl* the contact owns a 2015 subaru forester. While driving 2 MPH, the vehicle spontaneously accelerated and crashed into an electrical box. There were no warning indicators illuminated.
