The battery drains quickly when the car is switched off, potentially causing the driver to be stranded in dangerous situations without a functional car.

The radio/touch screen unit has lost its contrast. In bright sunlight I can see an underlying circuit pattern on the screen that makes it hard or sometimes impossible to see the back up camera. Instead of seeing the image from the backup camera all I see are lines. I can no longer rely on the camera for safety support.

The battery went dead on Jan 14th 2022. This isn't totally unexpected as this was the first time the battery needed replacing since the car was purchased new. However, after the battery was replaced the same day, three days later Jan 17th the battery was again dead. Since then, the battery has been replaced once more and again died on both March 27th and April 1st. The car is driven weekly at least and has no warning lights on. After the most recent incident it was researched more heavily and found that there is a potential class action lawsuit against Subaru for this exact problem. Though it hasn't been dangerous for us it could be potentially dangerous should the car decided to fully shut off in the middle of traffic.

This is the latest time in a series of incidents where the SUV would not start due to a problem with the main battery. New batteries drain very quickly after a series of electrical problems. So far, we have noticed keyless entry FOB says battery in the FOB is low and stops connecting (but then connects if we remove the key from it without us holding it to the button that turns the car on and off), we replace this battery but continue to have the same issues, front passenger side window is not able to be rolled down or up from driver side, as the battery continues to drain, gas gauges stop correctly registering amount of gas in the car, different warning lights light up on control panel without any sense of rhyme or reason, and overhead lighting gets dim. For a few weeks, the SUV blames the problems on the battery in the key FOB being low, even though it was replaced on December 15, 2021. When replacing the FOB battery did not work, we learned it was the actual main SUV battery that had been drained. It is now March 19, 2022, and we are having the same issues despite having only a moderate amount of miles put on the SUV and only 3 months of time passing since we purchased and installed a brand new car battery. We will have to spend money on batteries again.

Battery continues to drain when car is parked/off causing a required jump start and then recharging of the battery. Dealer replaced battery one time in 2019 (with expense to owner) and recommended driving car every couple of days to ensure it does not draw down. This is not normal. Battery continues to drain down. Owner purchased aftermarket AGM battery (May 2021) of higher voltage/capacity to attempt to reduce number of issues yet vehicle continues to exhibit parasitic drain and battery dies after 3-4 days (faster when it's cold). Dealer has looked at car two more times and claims this is normal and need to not leave car for multiple days without starting. There are multiple class action lawsuits claiming this issue so I am registering this VIN as an affected vehicle.

The contact owns a 2018 Subaru Forester. The contact stated that while attempting to start the vehicle, the vehicle failed to start-up. The vehicle was towed to the local dealer who diagnosed that rodents had eaten through the engine wiring harness. The contact was informed that the wiring harness was made of a soy-based material that was attractive to rodents. The vehicle was not yet repaired. The contact indicated that 2 weeks prior the windshield wiper fluid spray mechanism was inoperable due to a similar failure with rodents eating the soy-based tubing. The manufacturer was not yet notified. The VIN was not available. The failure mileage was 27,000.

There is a parasitic drain on the electrical system, including when the vehicle is turned off and nothing is left running. As a result the vehicle will not start. aI replaced the battery and experienced the same problem with a month. This is most problematic when the vehicle has not been used for at least 2 days or it's very cold outside. It's happened at least 10 times in the last 2 years. The most recent incident was yesterday. When I called dealership they denied any electric so issues with the 2018 Forester and want to charge me $75:to check the electrical system even though there's a lawsuit in Canada due to this same exact issue. Everytime this happens aI and my passenger s are put at a safety risk by stranding us because until help arrives.

I'm filing a complaint regarding a battery drain issue in the 2018 Forester Limited. After sitting idle and not being started for 1.5-2 weeks the battery is fully drained. Fully drained is defined as the car won't start with a portable jumper. The power source car needs to be running and connected to the battery of the dead Forester for upwards of 20mins to give it a partial charge prior to the battery dead Forester being able to start. I've been told various reasons from various dealers and cannot get a straight answer. [A] one subaru dealersip said it's normal to have a dead battery in 3days. [B] another subaru dealership said it was because I had a bad battery, but after replacing it the issue still persisted. I have made sure to manually shut off all lights including making sure the running lights are in the off position, not the automatic on/off position. This incident has occurred multiple times when traveling for week at a time and upon returning to the car to try and start it and it won't start. The same dealership [B] claimed that the parasitic draw was because I kept a cigarette lighter car charging adapter plugged in even though the car was off. I have read several other complaints about this issue regarding this car and hope there can be a recall/legal claim filed against subaru for this issue so they resolve it.

Bought vehicle June 2021. Battery failed multiple times. Sometimes it will start with a jump, but on 12/2/21 it was completely dead and required tow to Michael's Subaru dealer in Bellevue, WA. Battery was replaced twice within 6 week period.

Purchased this certified pre-owned, with warranty on 4/30/21. Required jumpstarts for dead battery five + times over the first 4 months, in moderate weather. Dealership confirmed that a new battery was installed at the time of my purchase. The vehicle has been towed to the dealership several times, they can find no issues. They then replaced the battery on 8/4/21 as the 3-month old battery failed testing per fail code JRGKF50-328J0D1. The car required a jump start on 11/21, again on 11/26, and I am currently waiting (12/2/21) for Subaru Roadside assistance, for yet another jump start. The car was last driven (commute home from work) yesterday. External temperatures have not been overly cold - yet. It should be noted that I turn off the radio and heat/air before shutting off the ignition. I have also disconnected my phone from the car's system in order to prevent any further battery drain. This is completely unacceptable. Roadside assistance takes a minimum of 60-90 minutes to respond. I work in Trenton NJ, where it is dangerous to be with a disabled vehicle for possibly hours awaiting service. I've owned over a dozen cars through the years, and have never experienced battery drain issues.

My battery keeps draining for some unknown reason. It's parked in the garage and locked but it is always dead when I need to use it. I need a reliable transportation and I have never had this problem before. I have had 4 - 5 jumps from my insurance company in the last few weeks. And it's dead again today after a jump a few days ago.

I left my car for 19 days while on vacation in my garage and the battery was dead when I returned. I charged the battery after jumping it with our other car. Now, 14 days later, the car would not start again and needed to be jumped. I have read about the battery drain. My care only has 21K miles.

There seems to be a fast battery drain on my car. After using the car and letting it stay parked (with all the interior lights off and checked to make sure everything was completely off) for 36hours, the car would not start. This has happened multiple times. It was not dead winter cold, it was approx 70º or hotter.

Battery was dead when we tried to leave, no reason as the car had been fully turned off. Left myself and my daughter stranded for 90 minutes in the heat without viable cell service, until I was able to find someone with jumper cables. Went to car parts store and bought a new $176 battery- as I wasn-€™t able to make it the 45 minutes to the dealer. Want reimbursement for battery and repair/explanation so it doesn-€™t occur again.

Multiple times, I've had the car parked for several days and when I try to start it, the battery is dead. I've had the dealer check the battery twice, and the entire charging system once. They couldn't find a problem. This doesn't happen every time consistently, but it's happened enough that I wanted to report the issue.

Battery keeps dying without daily use. I drove my vehicle less than a week ago, no lights left on, nothing in the charging ports, no doors open, and still the battery didn't have enough power to start. I've had to call AAA and have neighbors jump start my vehicle a few times but when I get my battery tested I'm told that my battery is fine and that I do not need a new one. Something is draining my battery and I don't know what.

I have had numerous times that my car would not start because the battery was dead. I upgraded my battery at purchase because I had the dealer install a remote start. Within a few months my car was completely dead and had to be towed to the dealer, 2.5 hrs away. Subaru replaced the battery with the biggest battery that would fit. The next winter, the same dead battery issues happened. It was suggested that I get a car starter jump pack, to keep on hand, which I used often. Then the battery stopped holding charge for even four days. So they recommended that I get a Trickle charge battery tender, so I did. The dealer thought it might be the remote starter, and replaced that. So far, it has been okay, but it is warmer weather now too. They also recommended that I keep the battery tender plugged in all time, year round, which seems crazy for a new car. I tried several times and ways to download my invoices showing these repairs. All failed.
