At the time,time, car was not fully 2 years old.. its brand new.This is an addition to a post created a week ago. After the dealership offered to detail the interior of the car to solve the sulferic acid feeling I noticed that the flap above the driving wheel started to feel warm. This happened right in the morning in February. I'm not sure if I am feeling an electrical voltage, smelling the exhaust or there's still sulferic acid in the car. Every once in awhile I my hair smells like oil.. Whatever it is it makes your head feel heavy. My toddler feels something because during a drive he will say " hot". This puts our safety at risk if we are smelling the exhaust or feeling voltage while driving in the car. Sometimes it smells like fuel I the trunk of the car or acidic
Battery draining requiring multiple charging.
The battery died after less than two years. There is a class action lawsuit related to recent Subarus draining batteries very quickly due to parasitic power drain because of a faulty electrical system.

The battery died after less than two years. There is a class action lawsuit related to recent Subarus draining batteries very quickly due to parasitic power drain because of a faulty electrical system. The 2020 Forester was included in the initial lawsuit, but this model was thrown out of the lawsuit by the judge since none of the plaintiffs owned a Forester. However, it is a known issue. Prematurely and unexpectedly dead batteries, as I experienced, can cause motorists to be stranded and face related hazards, as well as to incur unexpected costs. I spent more than $200 to replace my battery long before the minimum expected three-year battery life.
I bought my new 2020 Forester in November 2019. It now has 1604 miles on it. Twice already I've had to have it towed to the dealership because the battery was dead from just sitting in my driveway. The first time, February 2021, they said it was a bad battery. The second time, January 2022, they said it's because I don't dri…

I bought my new 2020 Forester in November 2019. It now has 1604 miles on it. Twice already I've had to have it towed to the dealership because the battery was dead from just sitting in my driveway. The first time, February 2021, they said it was a bad battery. The second time, January 2022, they said it's because I don't drive the car enough. Said I have to drive or idle the car for at least 15 minutes twice per week which is a waste of gas and time for something that shouldn't happen to start with! There are already lawsuits about this constant battery drain but the 2020 Forester isn't included and it should be! There is NO reason for the battery to constantly drain to the point that the car won't start when the car is sitting with everything turned off!

The contact owns a 2020 Subaru Forester. The contact stated that while driving at an undisclosed speed, the radio system malfunctioned, which caused the blind-spot detection system, headlights, and instrument panel to fail to operate as needed. Additionally, the eyesight system would inadvertently engage, which caused the vehicle to stop without warning. The contact restarted the vehicle to correct the failure. The vehicle was taken to the dealer, and AutoNation Subaru Scottsdale (15678 N Northsight Blvd, Scottsdale, AZ 85260) and diagnosed with radio software failure. The dealer replaced the radio on three separate occasions; however, the failure recurred. The dealer also reconnected the eyesight system and resolved the eyesight system failure. The manufacturer was made aware of the failure. The failure mileage was approximately 1,000.

Frequent battery dying problem in 2020 Subaru Forester from Grayson Subaru, Knoxville, TN I am a 67 year old woman who does much scientific research in remote places alone at night. During the day, I manage 3 farms 100 miles apart. I am constantly opening and closing gates, getting out briefly to check livestock and fix fences. If my keys are left in the ignition even briefly, as I get in an out for small tasks, the car battery is dead. Other times it is simply dead for no reason at all. In my over 50 years of driving all sorts of cars and trucks, I have never had this problem. I have had constant problems with this car battery dying in as little as 5 minutes after driving 50 miles. I have brought this problem to Grayson Subaru’s attention and spent hours waiting as they checked for problems. They never find anything. I have made numerous calls. They assure me this is “normal”. This is NOT normal. Not in my over 50 years of driving cars. I am forced to carry a car booster with me at all times. This is a TERRIBLE situation for a car which typically is owned by people who often camp, are doing sports in remote places or need a small rugged car for farm work or field research or outdoor activities. Here are just a few times I have contacted Grayson Subaru over this problem. I have had dead battery many more times than this (just in past 2 weeks Jan 5, 10 and 14, 2022), but have had to jump it off because I was in a dangerous. I bought the car in Sept 2021 from Grayson as a new car: Calls and visits to Grayson over the battery problem. Jan 22, 2021; August 11, 2021; Aug 23, 2021; Aug 24, 2021; Oct 5, 2021; Nov 17, 2021; Jan 11, 2022. I do not want to invoke the Tennessee Lemon Law (T.C.A. 55-24-101 to T.C.A. 55-24-112), but I also cannot continue to drive such an unreliable car. I see there is a “battery drain" lawsuit for 2020 Subaru Foresters. I believe this car has the same problem. What do I do?
The contact owns a 2020 Subaru Forester. The contact stated that the battery drained quickly, and the vehicle had to be jumpstarted after three days. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 2,000.
Liftgate open for tailgating party. Battery drained despite NO lights being on at all. This should NOT happen. Left me (50yo woman) and 3 kids stranded in a very bad part of town.
