Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Driving along and various system warnings came on, then started losing power, then the engine died and the car was completely dead. Got a jump start and the car ran for a couple of minutes and died again. Had it towed to a repair shop and when they checked it the next morning, they couldn't find a problem and it ran great for them. I replaced the battery and alternator just to be safe because we were about to leave on a trip.”

“The wiring system fails when the wiring - SOY BASED - is eaten by rats. SUBARU refuses to take responsibility for this. My car has less the 9500 miles and has had over $3500.00 work done to replace the wiring eaten by Rodents as this is considered my fault?.”

“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. …”

“I have had the wiring in my 2021 Subaru Forrester having to be replaced 2 times - once in front of car, once in fuel parts - due to Rodents eating the wiring. I have been told by Subaru Customer Service staff that the wiring is Soy Based. Subaru has a Class Action Suite in Hawaii for this exact reason yet Subaru in Macon continues to insist this is MY problem not theirs. I have Rodent repellant devices in my car. I am very frustrated, upset with being misled and no concern for the customer being offered.”

“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.”
