Subaru Forester electrical problems

1-16-24:car wouldn’t open and start; jump-started by AAA to dealer; dealer kept overnight & checked battery: said charge held, ready to go home. 1-30-24, 4 pm-ish: able to start n drive, but check engine& eyesight warning light came on- late in day, so didn’t drive to dealer. 1-31-24: car dead; jump-started by AAA again & drove to dealer. On 2-1-24, dealer sends a video & says replaced battery, but check engine light & eye sight warning light still on; investigated further & found there was a lot of water that had pooled under the passenger seat & caused some corrosion- I.e.: shorted out electrical system. I asked dealer to report to Subaru since this seemed like a car defect. 2-9-24- dealer says Subaru won’t repair it at their expense and it’s a 25 hour job & will cost a lot. Dealer wanted me to file a claim with my insurance, but car was not driven through rain, high water, or stored in a flooded garage or on a flooded street. The water in the car seems like a design defect on the part of Subaru.

The automatic shut off feature causes the car to lose all power. No power at all in the middle of traffic and I can't even use hazard lights to warn anyone. When at a stop the auto shut off turns off the car and when I take my foot off the brake it completely dies. It has happened 5 times in the last 3 days. Very dangerous. Imagine this happening on the freeway during rush hour. It's a miracle if no one has been killed. I saw countless posts from others on different forums. I have only owned this car for a week and half, taking it to the dealer today. This needs to be a recall paid for by Subaru, it is unacceptable.

I started the car to make a trip to town to run some errands. When I cranked the engine the Check Engine light came on. The S for Sport Mode was flashing and a No Eyesight warning came on. Also SRS Side Airbag light came on to indicate it was not working. And another light came on showing a car going out of its lane, but I don't know if it was the Lane Keep Assist light or not.

Driving my 2020 Subaru Forrester on 1/26/24, at night. Stopped at traffic light. Car started shaking, dash lights system lights came on. Turned off car and restarted. Car would not accelerate. Had towed to mechanic. Diagnosed as probable thermo regulator. Could not repair because part only available from Subaru. Called dealer who was not sympathetic or helpful. Told to bring in and leave. Would get to it when they could.

The vehicles battery does not hold a charge during short term, (3-5 weeks of storage). I understand that some prior years of Subaru vehicles have this same problem and there is currently a recall for this. I wonder if this battery problem exists in newer Subaru Foresters. When we purchased this vehicle as new we observed that the Dealership was having problems maintaining the charge on at least two other new Forester vehicles on display and had to replace the battery in one of these to start the vehicle and show it to other customers. We have had to have Triple A, (AAA), visit our home and jump start our 2023 Forester at least three times. We do not use the vehicle much and there is less than 1000 miles on our auto. The auto is stored in the off condition. No warning messages of lamps show the depleted battery conditions until trying to start the vehicle. We have recently, week of 1/15-22/2023, replaced the battery the auto came with and put in a new Diehard battery. We have photos of the old battery.

My vehicle starlink infotainment system does not work. This is a safety hazard because it prevents drivers from using their back up cameras and this car has many blind spots. This also frustrates drivers and causes distraction as navigation is not available. The screen display abruptly stopped working. I brought my vehicle to the dealer and their solution was to spend $1700 on a new infotainment system. Owners should not have to be paying to utilize safety features marketed for the vehicle they bought. There were no warnings prior to the system breaking.

When I am idling at a stop sign or sitting in traffic and I have come to a full stop, the car's engine shuts down as a gas-saving feature. This is not the problem! The problem is that sometimes when this feature engages, when I lift my foot off the brake to start driving again, a shrill constant ringing sound starts and the engine won't power back on. There is an error message that comes on that says "eyesight disabled." When this happens, none of these factors (the ringing, the error message, the dead engine) stop until I put the car in park and power it down completely, then restart the engine. Then none of the symptoms are there anymore and the car drives normally. I have not noticed any consistency about when this problem does or does not happen - it occurs in all weather types, temperatures, times of day, slopes/flat roads. I sometimes go months without it happening, and other times it happens twice in several days. The only consistent thing is that it only happens when the car is at a full stop and the engine has shuddered off to save gas. I live in Chicago and almost exclusively drive short distances in the city, I hardly do any highway driving. This has happened maybe 20 times since I bought the car in February, 2023.

All of a sudden, the eyesight and collision prevention stopped working, the check engine light came on, the blue light thermostat indicator came on. We had no heat. The flashing "S" (sportsmode indicator) came on. We were driving on the highway and still over an hour from home. It was snowing, we could not adequately clear the windshield of fog so our visibility was severely compromised. We lost all Eye Sight capability which meant that we were vulnerable if there was ever a crash or an obstruction in the roadway.

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?
