2019 Subaru Forester Electrical System

My 2019 forester touring. The sound system will randomly raise to extremely high volume. It’s an extremely loud, distorted, static version of what you were listening to. You cannot turn it down with the volume control with knob or power it off. It is unresponsive and you must wait 5-10 seconds for the sound to go back to normal. Not knowing when it’s going to happen scares the heck out of me. I’m afraid to drive off the road or cause an accident when being startled in this way. This has been happening since one month of my owning the car. (Ordered it, got it October of 2018] I’ve had it to the dealer numerous times and called Subaru of America. I was told if the problem doesn’t duplicate at the dealer nothing can be done. I only have 24k miles on it. It’s not safe! I now a have grand baby to drive. I also wear a hearing aide now which I cannot drive with as it’s way worse with the high volume the problem produces.

The contact owns a 2019 Subaru Forester. The contact stated while driving approximately 55 MPH, there was an alarm heard before several unknown warning lights illuminated and the vehicle lost motive power and decelerated to 35 MPH. The contact shifted to neutral to restart the vehicle. The contact pulled over to the side of the road and waited for a while before continuing to drive. The eyesight, brake light, automatic transmission, oil temp, and several other warning lights illuminated intermittently. The failure occurred a second time on the same day. The dealer was contacted and advised the contact to take the vehicle to the dealer whenever the lights were illuminated. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the dealer for assistance. The failure mileage was 119,000.

Subaru Forester 2019 January - February of 2025: issue initially presented as the hatch beeping, indicating that it was not closing fully. The hatch would not pop back up as if something was in the way, just remain down & continue beeping. The car would then not start, with only the hatch beeping noise (beep beep beep) going off. When I drove it, it kept warning me that the hatch wasn't shut completely. After I parked it in the garage, the next morning it would be dead. The issue was supposedly resolved in February of 2025 as I replaced the battery on my own and replaced this part: 29182AA060. Schomp Subuaru reported no issues with their diagnostic tests. November 30th - December 2025: I started the car just fine. When I opened the trunk and closed it, it gave me three beeps and wouldn't fully close, even if I pushed it shut and locked it. The next morning, the car would not start - the battery was dead. The tow company also could not jump start the car. As the car was being towed, the hatch alert was the only thing working/beeping. Even when not trying to use the hatch. I have used the car every single day up until this issue started. I have not left the keys in the car. The car is now back at the dealership. The unreliability of this can/has left me and my passengers stranded and cold. The dealership found no issue the last time this occurred even though there was a class action lawsuit about this exact issue, but somehow my car was not considered included. I cannot have Subaru tell me that there is no issue again.

The issue started last year over a period of several months when my car kept stalling at a traffic light. After stopping on a red light my car stalled. I had to shut off the car then restart to get it going. Had the battery replaced and problem was gone until this week. Car stalled at the traffic light again (in the middle of busy downtown and being the 1st car at the intersection), but this time it wouldn't restart and battery light turned on when attemped to restart. Called Subaru road assist and requested jumpstart service. While waiting for road assist to arrive, attempted to jumpstarts with a manual jump starter, but didn't work. Attempted with the jumpstart cables, but still didn't work. Subaru assist arrived and was able to successfully jumpstart my car. The Subaru tech assessed my battery and showed 75% battery life. Drove home on the freeway for about 25 miles. The next day drove to and home from work (25 miles reach way) with no issues. The following day, my car wouldn't start from my home. Jumpstarted with the manual one and brought it to the shop a few miles away. Got to the shop and turned off the engine. When turning on again, it wouldn't start.

The battery on my 2019 Subaru Forester was replaced in September 2022. It was the best battery available offered at Les Schwab. But a few days ago, the battery was completely dead again and couldn’t even be jump started with my Jump N Carry after being parked in my garage for ~3 weeks. After taking out the battery and getting it fully recharged at Les Schwab, they also tested the battery saying it’s still in good shape. I suspect there is parasitic battery drain issue going on with this model.

As I was driving, every warning light came on, my car emitted a high pitched alarm and the car stopped working. This happened twice. I had to put my car in park. Turn off the car and turn it back on to make it driveable. I took it to the dealer and was informed that the battery and starter required replacement. The battery was covered by an extended warranty (I paid $100 or 20% of the cost), but the starter was not covered by any warranty since my car has 41K miles and is 5 yrs old. I contacted Subaru and they agreed to pay $800 towards the $1209.13 repair. My Subaru Case # 241016-1801159. I believe my starter failed because of the automatic start/stop engine feature. I asked the dealer if the starter failure could have been detected during a regular maintenance and they said no.

After starting these lights came on the dashboard: check engine, flashing I drive, no eyesight, rab off. Seems related to start/stop system which randomly dies when I release the brake. The whole dash lights up and I have to put the car in P and start it again. Thanks.

Car suddenly stopped accelerating several times over the course of several months, at seemingly random speeds, once even at a full stop when attemptign to begin acceleration. Required to turn it off and on again (in park, break still works) and it works again. I towed the car to the dealership, and they told me after a few days that they could not recreate the issue and nothing was certifiably wrong with it. The only thing that came up on the sceen was the EYE LIGHT system wording with a slash through it.

The original battery does not support the CAN system and replacing the battery does resolve the issue. The system will shut off while stopped at a light to save fuel, and turn back on when you press on the brake or the gas. There is an error where the vehicle will try to start itself when you’re not even cranking it. This can be dangerous if the car shuts off at a light and won’t turn back on because the feature drains the battery. This needs to be a recall as Subaru is aware of the issue and implemented a new battery for the vehicles and want to charge double. Why should the consumer pay for something that the company is aware is a problem? And came up with a solution to the problem, but is trying to profit off of it instead of fixing their mistake?

Subaru has issued a service bulletin regarding this issue. The vehicles auto engine on/off (gas saving feature) fails to restart while driving due to OEM battery is known to be too weak. Only way to resolve the issue is to replace with higher capacity battery requiring new battery tray and additional new equipment. Current, customer has to pay repairs out of warranty. Incidents are frequent and reoccurring.

The contact owns a 2019 Subaru Forester. The contact stated while driving 60 MPH in a thunderstorm, the vehicle lost motive power inadvertently. The check engine, the Vehicle Dynamic Control, and the Eyesight Driver Assist system warning lights were illuminated. The contact was able to pull to the side of the road. The contact stated that the engine continued running, and the instrument panel functions were operable; however, the vehicle failed to respond upon depressing the accelerator pedal. The vehicle was towed to the local dealer, and the vehicle operated as needed. The dealer test-drove the vehicle but could not determine the cause of the failure. The contact stated that she picked up the vehicle; however, the failure recurred while driving. The vehicle was taken back to the dealer, and the dealer diagnosed that water was leaking out of the thermal control valve and onto the electric wiring. The vehicle was repaired under Warranty. The manufacturer was notified of the failure. The failure mileage was approximately 16,600.

Sun roof malfunction. Would not open. Once open, went on highway and had to close it. This was distracting to me, driver, and put us all at risk for no weather protection or debris on highway. The sunroof malfunctioned again by not responded and would not close. No warning for any errors. Has not been inspected by insurance. It is available for inspection. Online forums show multiple people are having this issue!

Automatic Rear lift gate will not raise (but does unlatch); the lift gate cannot be raised manually after latch is released. One can only open it about 6 inches until there is heavy resistance- like the strut has seized or a sensor has triggered a brake. Now, the rear gate cannot be opened in an emergency.

The Starlink Infotainment system started to continually reboot despite any attempts to reset it. With the car shut off, the CD player began continuously spinning up then winding down. This drained the battery. I had to pull a fuse labeled BACKUP to prevent this from happening. This has rendered the backup camera unusable.

Apparently the electrical system drains the battery when the car is not being used. If I let my car sit for 3 days the battery will be dead when I come out to use it.

First, the driver's side window would not go up when rolled down, but instead went up and down on its own, until I stopped the car and restarted it. A few days after that, on Friday, January 13, 2023 while on my way to work, I was stopped at a traffic light. All of a sudden beeping started happening, the "Eyesight" light came on, other things were showing, and the car died. I was too freaked out to notice anything else. I put the car in park and restarted it, and it was fine. Today, January 16, 2023, the exact same thing happened when I was stopped at a traffic light, again on a very busy highway. I am extremely worried and will be contacting the dealership tomorrow.

Battery drain quickly. Overnight battery drain. Car driven for over 40 miles and the following day the battery is drained and won't start. Car left for one week with out driving - battery drained and won't start.

Failed thermo control valve assembly, Subaru part #21319aa010 Subaru is aware of the problem but new parts are backordered, with delivery perhaps weeks away as this is apparently a common problem. The local dealer indicated Subaru will pay for parts and labor (this is a verbal offer only), which again suggests this is a known problem. The failure led to automobile not performing and a two to service location. As a known deficiency, why has this not incited a recall or other notice?

While driving, the vehicle stopped driving midride. I attempted to turn off the car and restart the car, but it had issues. This happened on 3 separate occasions. I believe the battery was being overdrawn. Two times this happened on the highway and I lost the ability to stay accelerated. I have had the dealer inspect it twice and they found no issues. Shortly after breaking down the third time, a separate car repair shop tested the battery and it tested good. The check engine light appeared and made mention of the Eyesight system.

Driving vehicle in a busy intersection and all of a sudden the electrical power went out. Battery is completely drained.

Auto start failed multiple times leaving car disabled for a short period of time in traffic creating safety hazard. After asking the Subaru service center about it they said there was nothing they could do about it because there was no lights on the dashboard. Eventually they informed me at the last service that the battery needed to be replaced.

In July my car kept dying and I had to jump the battery frequently. i Had it serviced at Hayesville firestone and was told it was ok. Problem continued. had a mechanic suggest I get another battery , whick I di at car quest. Has been fine since. I just received a notice of battery drains on Sub forester, so I am reporting this to you. No injury was involved

The car's battery is unable to start the car. If the car isn't used for one or two days, the battery power is drained so low that I can't start the car. This problem began very soon after purchase and has not gotten better. The dealership told me I was keeping the keys too close to the car and that was causing the issue. However when the keys are kept far away the problem continues. I'm also having a problem with lifting the back hatch. Sometimes it just beeps and doesn't open

Battery has died
