1 Brake Light On problem

Failure Date: 08/31/2020

This car was repaired under campaign 19v149000 on July 27 for the brake light switch issue. Since the repair of the recall, I have taken my car back to International Subaru in tinley park, IL for follow up service related to the replacement part. The problem I've encountered on a number of occasions is the car alerts that there is an issue stating "hill start assist system needs to be checked" while the car is in motion. The car then cuts all throttle capabilities for approximately 5 seconds and the car just coasts before resuming taking a throttle input. When this happens the car is just coasting and drops 15+ mph in speed. This alert seems to be triggered randomly and it causes serious safety concerns when without warning my car suddenly loses any usage of the throttle. This problem has been traced back to the part replaced in the recall and the dealer found the records in the car's computer showing the switch was active when it wasn't being pressed. This issue first surfaced on 8/31/20 but has come back numerous times since then. Furthermore, I had issues where the brake lights were on on the car overnight with the switch active with no input causing a drained battery. This is a more serious issue than just lights because the car's throttle cuts out without warning and this has been traced back to the switch on my car. I would rather have the original recalled part replaced in my car compared to the recall replacement part.

2 Brake Light On problem

Failure Date: 02/14/2019

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.

3 Brake Light On problem

Failure Date: 11/07/2018

Similar complaints already logged. While driving at any speed warning lights for abs, eye-sight, dynamic vehicle assitance, hill-start assistance come on. Took the vehicle to the dealership to get it checked out. They replaced the brake light switch and said the problem was fixed. Upon driving, the problem persisted, this time with the brakes being applied by the vehicle itself while in motion on a highway moving at highway speed despite my foot not being on either the brake or gas pedal. With the decrease in speed, I attempted to accelerate the vehicle to no avail. At this time I pulled the vehicle off to the shoulder, put it in park, and then back into drive to see if the problem had been corrected. I pressed the accelerator for a period of time before ultimately the drive reengaged. . Read more...

4 Brake Light On problem

Failure Date: 09/25/2018

Hello, Subaru needs to add Forester models to its recall of 72,000 vehicles due to problems with their automatic braking system (abs), faulty brake light switch sensors. I just had to have my Subaru Forester's brake light switch replaced for the 2nd time in 2 years! both times, I was driving on open highways far from home doing 55mph on flat terrain when all of a sudden the 3 lights came flashing on my car's dashboard: hillstart assist system, abs, & vehicle dynamics control systems. I was extremely alarmed both times that my vehicle might not be safe to travel, especially since I was on highways and far from home. Could it be that when the part was replaced 2 years ago it was replaced with yet another faulty part?? two years ago, the repair cost was covered under Subaru new-car warranty. This second time, my extended warranty paid some, but I am now out of $100. Deductible, --- ($160. Labor cost(?!), to replace a $16. Part! total billed was $175. 68) I am not confident in the replaced sensor, and am scared to drive my Forester for long-distant trips for fear it may happen again, since it has already happened twice in 2 years. I believe that Subaru should refund my $100. Since Subaru has known about faulty brake sensors formally recalled in other models. Upon searching the internet, I discovered that faulty brake switch sensors have been a well-known problem with Subaru for many years, and recalls for this part should apply to the Forester as well as other models. I also believe that Subaru needs to add Forester models to their list of recalls for faulty brake light switch sensors. I/we Forester owners should not have to keep paying for known faulty parts, nor should we be scared for our safety to drive our newer model vehicles. Please help! r/ ms. Kotsiras.

5 Brake Light On problem

Failure Date: 06/14/2017

While driving, the electronic stability control, the hill assist brake and the abs lights randomly deploy. Happened 3 times in 24 hours. Turning the car off and back on seems to clear the issue. However, after that, now two times while traveling at a regular speed, the braking system automatically applied itself, including the cvt engaging into low speed and forcing the car to drive only at 10-20 mph. As well, when this occurs the braking system does not work. Other reads sound like a faulty brake light sensor or sensing system, but this is a potentially fatal malfunction as one traveling 60 mph on the highway was suddenly stopped with no warning. Then when trying to get to safety, the brakes would not work while attempting to come to a stop at a light. The vehicle seems to "reset" and be fine for a few miles, only to either go to the all lights on system (abs/hill assist/stability control) or go into the braking/cvt error as well. Will have the car towed to the dealership, but this is a serious safety concern that is electronic in nature as the default fall back is not a manual working brake system but seems to be a non-working brake system.

6 Brake Light On problem

Failure Date: 08/09/2016

Our 2015 Subaru forest will randomly while driving have all of it warning lights come one. Eyesight, hill assist, abs, lane departure, ect. If you stop and put it in park then it will not come out of park unless over ridden. I called in to Subaru and they said "2015 Subaru Forester right? it probably has a bad brake light switch or brake light sensor, which means your brakes will not light up while driving. This seems to be a known issue to Subaru as I have seen many examples of this happening to other people on Subaru boards. I was out of warranty and they want me to pay 170 dollars just to diagnose the issue when they clearly know what the issue is. This is a critical safety hazard, if my brake lights fail to light up while driving due to a known defect, I or someone else could be injured or killed due to them not being able to recognize my braking.
