“Several times our 2019 Subaru Ascent battery has drained down to low levels requiring jump starts. This last time was this winter and -15 degrees outside and was very dangerous for her. The alternator does not seem able to keep up with the load. I have heard of many other people having this problem. It sat overnight on both occasions.”

“The engine keeps stuttering when driving and slowing down to stop at a traffic light. Couple of times, it should shut down and I have to restart the car. I do ensure the car is warmed up to a minimum of 7-10 minutes before starting. It only started recently but I am worried that this will happen more and suddenly stop when driving and me getting involved in an accident.”

“At only 17.6k miles, the battery in my 2019 Subaru Ascent was completely drained overnight, for no logical reason. I called Subaru roadside assistance to give me a jump and I let it run for 33 minutes then took it for a 10 min drive. The battery was dead again the next morning. Vehicle was stationary overnight and until the 10 min drive. During this time the tailgate would persistently beep, trying to open.”

“My fuel pump was replaced (according to the dealer) based on the most recent recall. However now it idles and runs rough just a short time after this service. I recently read there is another lawsuit or issue with this fuel pump and the symptoms are the same.”

NHTSA complaint #11363767, filed 2020-10, 23,314 miles

“I was in traffic and the dash- started flashing and everything at once started shutting off and then brake was applied on its own. Very scary while in traffic- I have been waiting for a tow truck for over 3 hours. Dials: at oil temp flashes, all electronic things is all off and lit. Transmission and braking issues- all at once. City street braddock rd and I pulled off at kings park shopping center in front of wells fargo and cvs, stationary.”
