“Vehicle vibrate starting at 50 MPH and gets excessive at 65mph and up, while cruising in the highway. The vibration can be felt on the steering wheel and the driver seat seat.”
NHTSA complaint #11292190, filed 2019-12, 20 miles“Ever since we purchased our Subaru, the RPM's seemed a little off and then at random times when I put it in reverse, it will just idle and I will slowly press on the accelerator and it will not engage in reverse and then random pop into gear and lunge backwards. It doesn't happen every time, but is scary when it does. This has been happening pretty much since we purchased it”
NHTSA complaint #11443999, filed 2021-12“I purchased a 2020 Subaru Forester in 2020. Last week, the Check Engine light came on and it was due to the thermo control valve that need replaced. My car was outside of warranty at 70k miles and Subaru’s customer advocacy office will not reimburse despite this being a faulty defect for many 2018-21 Foresters. There is a class action lawsuit filed but I’m still out $1900. There should be a recall and I should not be paying for this manufacturer defect.”
NHTSA complaint #11580521, filed 2024-04“While driving, the 2020 Forester, the check engine light, collision light, eyesight function lights all went on at the same time. I brought vehicle to check diagnostics and it is showing Engine Coolant Bypass Valve A Control Circuit low in Power Train System. Their were no messages prior to all the lights turning on and I was able to bring into the dealer for oil change but not able to make an appointment for repair for a few days from now”
NHTSA complaint #11535457, filed 2023-07“Thermo control sensor failed which will damage the motor if overheating dealer says it's going to cost me $1500 and it isn't covered under drivetrain warranty which is 5 years 60000 miles I have 27000 miles”
