Subaru Forester warning lights comes on

Filed Nov 1, 2026 · Electrical, Engine · TX

When coming to a stop, the auto start/stop system shuts the engine off and it fails to restart. All dashboard warning lights illuminate. The vehicle must be shifted to Park and restarted manually with the start button. The component that failed is the auto start/stop system; the exact cause is UNKNOWN. The vehicle is available for inspection upon request. This put safety at risk because the vehicle was left immobile in live traffic at stops until it could be restarted. There were no warning lamps or symptoms before the failure; the warning lights come on when the failure occurs. The vehicle was inspected by Gillman Subaru Southwest on October 229, 2026, and the dealer stated the battery performance was bad and in critical condition.

2021 Subaru Forester The vehicle has experienced recurring electrical and battery-related issues for several years. The original battery was replaced by the Subaru dealer with a larger-capacity battery because of repeated starting concerns. The replacement provided only temporary improvement. The vehicle continues to experience rough starting on a regular basis, even after installation of a newer aftermarket battery with a higher cold-cranking-amp rating. The current battery is approximately five months old. The most significant safety concern occurs during Auto Start-Stop operation. On multiple occasions, the engine has shut off at a stop as intended, but then failed to restart when attempting to move again. When this occurs, multiple warning lights illuminate on the dashboard and the vehicle is unable to proceed until it is shifted into Park and restarted manually. Because of this issue, I now disable the Auto Start-Stop feature on every drive to avoid a potential failure to restart while in traffic. The issue has been ongoing for years and has occurred with multiple batteries, including the dealer-installed replacement battery and a newer aftermarket battery. The dealer suggested that an aftermarket dash camera could be contributing to battery drain. The dash camera was disconnected, but the problem continued. I am concerned that failure of the vehicle to restart after Auto Start-Stop operation could leave the vehicle disabled in traffic and create a safety hazard. The condition appears to involve the vehicle’s electrical system, battery management system, charging system, Auto Start-Stop system, or a combination of those components. The vehicle is available for inspection upon request.

I am filing this complaint regarding a recurring and dangerous safety issue with my 2021 Subaru Forester. The auto stop/start feature intermittently fails to restart the engine after it shuts off when stopped. When this occurs, multiple dashboard warning lights come on, an alarm sounds, and the vehicle requires putting the transmission into "Park" and shutting it down completely before it will start again. This has happened multiple times at intersections, traffic lights, and freeways during rush hour (stopping and starting frequently), leaving me temporarily stranded in live traffic. The local Subaru dealership service department was unable to replicate the issue, however upon inspecting the vehicle's charging system, the battery was found unable to hold charge from the alternator and was replaced on June 9th, 2025. Now after less than 1 year of replacing the battery, the problem persists. I have been made aware of TSB 16-118-24R (TCM reprogramming for auto start/stop restart failure) and TSB 09-80-21 (Thermostatic Control Valve failure) which appear directly related to this issue. This is a serious safety hazard. A vehicle that cannot restart in live traffic puts the driver and other motorists at significant risk of a crash. I am requesting that the federal safety agency investigate this issue and consider a formal recall.

This vehicle has died 4 times in one week. when this happens, multiple lights have flashed in the dash board, including the "eye sight" warning. Then, it would not restart but continued to "turn over" when the ignition button was pushed. One instance was on a busy street at a stop light, another at a busy intersection in the inner left turn lane, the other 2 instances were in parking lots. The first 2 times the vehicle was able to be jump started and was not taken to the dealership. The 3rd, it was jump started and taken to the dealership. They said the battery was slightly low, but had sufficient charge. They changed the fob battery, and topped off the car battery. That was all. The next day was the episode where it died in the turn lane. I had it towed to the dealership. This time they changed the battery to a more high capacity battery, and admitted that these vehicles have a battery put in them at the manufacturer that is not strong enough for the systems it runs. I even found a service bulletin about it online, #TSB 07-218-23R. This should be a recall item, and they should have changed this battery at my first visit! A vehicle suddenly dying on a busy roadway puts those inside at risk, as well as everyone around them. Very disappointed in this 2023 Subaru Forester Premium.

While driving the car, the engine stops completely. After a few seconds, it can be restarted. It does this several times a week at random intervals. It's very dangerous since it usually happens when we're driving in traffic. The dealer checked it out in July but couldn't find anything wrong. Even though it's a serious safety problem, they said to keep driving it until it does it every time the car is driven or until the car won't run. When this happens, all the dashboard warning lights come on and the word "Eyesight" is displayed with a diagonal line through it. A warning buzzer also sounds. This started last summer with very infrequent occurrences and is now several times a week.

I have a 2016 Subaru Forester and started 3 weeks ago with a problem when I turn it on all the lights on the dashboard turn on and the car won't star. The mechanic has changed the battery and the problem continues. It's happened three times now that it's suddenly shut off while I'm driving. It was very scary. Now the mechanic said that I have to take to the dealer because it is the body control module.

While at a Stop as the engine turns off and awaits decompression of brake to turn on again vehicle moves forward bit, then the engine shuts down while in drive (stalls) had a vehicle hit me in rear but luckily I had my trailer hitch on because it saved me from body damage . I had to place in park and restart this has happened several times before and I’m kinda nervous and makes my wife nervous when stopping at lights or stop signs it might turn off in the middle of the intersection. When this occurrence happens all dash lights pop up … I checked engine with code reader after the incidents but it doesn’t give out any info on what could possibly be happening. I had the Dealership change the Thermo control module in 2025 but these occurrences has happened before and after the TCM replacement.Having the dealership check is like wasting my time and money because they aren’t able to pinpoint the cause without a code . There has to be a problem somewhere in the system it’s just that the dealership in Hawaii has no clue ..

While driving on public roads, all dash warning lights illuminated simultaneously. The instrument cluster displayed “EyeSight OFF.” At the same time, the electronic parking brake engaged / the vehicle would not accelerate and required me to stop and shift to Park. The only way to restore drivability was to turn the vehicle off and restart. This has occurred intermittently, including in traffic, creating a serious safety hazard for myself and surrounding drivers.
