36 Electrical System problem

Failure Date: 10/29/2021

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.

37 Electrical System problem

Failure Date: 10/21/2021

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.

38 Electrical System problem

Failure Date: 10/16/2021

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.

39 Electrical System problem

Failure Date: 09/08/2021

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

40 Electrical System problem

Failure Date: 09/03/2021

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.

41 Electrical System problem

Failure Date: 08/09/2021

With car in park key will not turn to the off position and can not be removed.

42 Electrical System problem

Failure Date: 08/01/2021

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.

43 Electrical System problem

Failure Date: 07/08/2021

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.

44 Electrical System problem

Failure Date: 06/23/2021

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.

45 Electrical System problem

Failure Date: 06/15/2021

We have discovered that our 2019 Forester has a parasitic battery drain of almost 1 amp when the car is off and the hatchback is open. This resulted in full battery drain several times until we did several tests to determine the root cause of the problem (Subaru was of no help). This led to replacement of the oem battery at about 52,000 miles.

46 Electrical System problem

Failure Date: 06/12/2021

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.

47 Electrical System problem

Failure Date: 05/13/2021

Battery drains for seemingly no reason. The radio or lights are not left on that would make the car drain while the car off. I had to replace the battery on 5/14/2021.

48 Electrical System problem

Failure Date: 05/08/2021

1. The car battery failed on six separate occasions within a 12 month time frame. First on may 8, 2021, August 21, 2021, September 9, 2021, November 5, 2021, February 5, 2022, and on March 28, 2022 2. The drivers safety was placed at minimal risk on one occasion since cars were lined up behind in a parking lot when the car would not start. 3. Yes, the problem has been reproduced due to the number of different times the battery died and the car would not start. The problem has not been confirmed by a dealer or independent service center. 4. No, to date the vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. 5.

While getting a 2 hr dental procedure, there was an unexplained battery drain, leaving the car dead. I paid aaa to give me a roadside emergency jump. I had had no previous issues.

51 Electrical System problem

Failure Date: 11/01/2020

A few incidents have happened since the latter half of 2020: while at a stop light that turned green, my car stopped moving for a few seconds despite pressing on the gas pedal and the rpm went up to 6/ loudly revved. I was almost rear ended at this light. The car has also had this lack of movement issue on the freeway while in traffic. My car jerks several times on slight inclines especially after surpassing 40 mph. Often times, I cannot accelerate past 40 mph regardless if the drive is on a flat surface or an incline. The rpm will increase, but the gear feels like it will get stuck and the car makes a loud noise. This is the most noticeable going from 40 mph to 50-55 mph. These incidents are on city streets. However, power often gets lost going on to freeways for the same reason. I cannot surpass 40 mph when entering a freeway and was almost sideswiped on the driver's side by an impatient person entering too early where the on-ramp merges with the freeway because of this. While on a freeway, the car will continue to accelerate despite attempting to slow it down by pressing on the brake or coming to a complete stop. This has also happened on city streets and poses a safety issue. The acceleration when this happens is much faster than when I try to manually accelerate the car myself in other contexts, like mentioned above. I believe it is the cvt as this seems to be a common problem with cars of my make, model, and year.

52 Electrical System problem

Failure Date: 10/15/2020

First, driving on the highway the air conditioner stopped working. Second, the very next day, the vehicle began to make noises (squealing) when driving it anywhere. Streets, turns, hills etc. Then it began race and it felt as if the back tires were racing to catch up to the front tires. There was lurching forward. Shuddering. No dashboard warning lights came on. I called the dealership, then took it to the dealership. It was scary to drive it there. I felt like the transmission was going up. Third, the tailgate, ( in or out) release buttons were not working consistently (repeat complaint). I left the vehicle at the dealership and telephoned Subaru of America. This 2018; I had owned for exactly two months. I had only driven the car approx 1200 miles total. Mileage 47,000. The dealer has repaired the ac and cvt transmission. The ac is a known problem and it was the condenser that was leaking and needed replaced. The cvt is also a known problem. The service tech test drove the vehicle and able to duplicate concern. He found the rpm increased and the squealing could be heard. Vehicle would shudder. When he removed the pan he found metal in the oil. Confirming the cvt (transmission) needed replaced. Repairs were made under the extended warranty. Given the information found on the web regarding these problems it was important to report that these problems continue. Safety is concern.

53 Electrical System problem

Failure Date: 04/15/2020

Forester was parked in under ground parking garage for between one and two weeks. The battery was completely dead, no sound at all when I tried to start it. The only door that was locked was the rear hatch door. Neighbor brought a battery charger and got the Forester started. Following that, I drove it to the local Subaru dealer and ask them to check and see if anything was draining the battery. They check everything and did not find any problem. The fellow at the service desk said that starting a car is the biggest drain on a battery and if the car isn't driven enough between startups, it tends to bring the battery down. He recommended particular battery charger which he said I could purchase at walmart. Since I only have a little over eleven thousand miles on my Forester, and I have never had this situation occur with any of my other automobiles in the past. I do worry about what would happen should I leave my car parked at the airport for a couple weeks and there is no place to plug in a charger. I still love my Forester.

54 Electrical System problem

Failure Date: 01/01/2020

Windows get locked and I'm not able to use the switch to unlock the windows and either side. Issue was reported. Subaru corrected the issue but it still happens. Once Subaru dealer helped via phone conversation to reset but this is a constant issue. I feel trapped in my car and I have to open my door to reach for a ticket while at a parking lot. Can't role down my window at the gas station. This can happen stationary or in motion. This is definitely a safety hazard. Also, while driving the music goes to a high to low volume and vise versa either on it's own or when I hit a bump. Very disturbing and scary at times especially when I'm on the highway.

55 Electrical System problem

Failure Date: 08/16/2019

The airbag system became disarmed and seatbelt warning light came on when smartphone weighing 3lbs was on front passenger seat. This occurred multiple times the passenger front seat sensor is supposed to become armed when a 40lb passenger sits in passenger front seat only. Reading through the owners manual states that both driver and passenger airbags may not deploy which puts driver and passengers at risk for injury.

56 Electrical System problem

Failure Date: 10/09/2018

It seems that my car has a poorly designed/not-current-limited usb jack, which fails to prevent a phone charging cable with shorted or shorting-intermittently interval power wires from burning up and possibly causing a fire. The details of my burnt-cable event: on Tuesday evening oct. 9, 2018, I got into my car in my garage. I then started the car. The usb part of my iphone cable was already in the car's usb port, I believe. While the car was still idling in place, I then plugged the lightening end of the cable into my iphone's port to charge it. I was still idling in place when I heard a sound similar to a plastic bottle popping inward or outward and started to look around in my car for what's going on. I then, within seconds, I believe, started to smell a burning smell. I opened my center console, since that was the most recent thing I had handled, and had ports in it, and I smelled the burning smell more. I quickly pulled out the cable from the usb port and the iphone itself. I went onward with the night's activities, and then later that night, back at the car, inspected the cable and saw that the lightening end (iphone end) was distorted, with a wire protruding, and a brown burnt spot. I believe this could have turned into a fire if I hadn't quickly removed the cable from the usb port.

57 Electrical System problem

Failure Date: 08/07/2018

While in reverse, audio control is lost. Alteration to channel or volume or turning off audio is disabled - which can be highly distracting if the setting were left extremely loud since the audio will initialize several seconds after starting and reversing is already in progress at that time.

58 Electrical System problem

Failure Date: 04/30/2018

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.

59 Electrical System problem

Failure Date: 03/22/2018

Outside temperature readings are between 3-7 degrees off. Dealer says that is normal. An I to assume the tire pressure, engine coolant temperature and oil pressure gauges are also off ?.

60 Electrical System problem

Failure Date: 02/11/2018

The eyesight had been manipulated to a warning even when there's no obstruction while driving forward, while backing up it gives a warning that someone or a vehicle is adjacent to my car. These are just a few of the problems I encounter. I have an idea who's behind this. But I cannot prove it. Someone very knowledgeable in computer security within my vicinity. It compromises the safety feature of the car while driving and even backing up in my garage.
