2019 Subaru Legacy

The contact owns a 2019 Subaru Legacy. The contact stated that while the vehicle was parked, there was an abnormal sound coming from the engine compartment, and the vehicle intermittently stalled. The contact stated that seconds later, the vehicle returned to normal operation. No warning lights were illuminated. The failure reoccurred on several occasions. The vehicle was taken back to the residence. The vehicle was not diagnosed or repaired. The contact researched and became aware of an unknown NHTSA Campaign Number; however, the VIN was not under recall. The manufacturer was not notified of the failure. The failure mileage was approximately 15,000.

Multimedia component is not working correctly and it could cause an accident due to trying to change/control the component over and over again. It has a mind of its own. I turn it off and it turns on by itself. It switches radio stations by itself. The screen changes apps all by itself. I can't correctly use any of it anymore. I try using my phone and even though I don't want it sent to audio on the car it switches to it and then the conversation cuts in and out. I've tried resetting it a million times but it's useless anymore to even do that. I haven't brought it to a dealer as of yet. I looked it up and seen there are other complaints with this same issue. I received a letter for reimbursement if I changed it out but I didn't do that because I was able to reset the system at the time. I feel Subaru should be responsible for this as they know it's happening to vehicles and they've reimbursed for it.

Due to a dead battery issue in 2025, I bought a new battery. A year later, the car wouldn't start & I finally got it jumped. Ran fine for 3 weeks, then wouldn't start again. I brought car back to the Interstate battery shop, who tested the alternator, which was fine, but he said the battery was appearing low. After researching this problem, I discovered there's a known issue that the battery dies due to a parasitic draw. Subaru knows there is a problem but refuses to correct the issues. The dealer I bought the car from neglected to tell me there was an existing issue and will be happy to charge me $500+ to diagnose. This is a major defect on Subaru's part, and all future buyers should be aware of it!

Unintended acceleration, on 2 occasions. First occasion, car was in DRIVE waiting at a traffic stop and the engine radically increased it's RPM from idle to over 6000 RPM, remaining there. Braking control maintained the automobile's position. Shifting the car into neutral caused RPM to increase further. The car was shut off, restarted, and seemed to function normally. On the second occasion, which occurred later the same day, the car was off and then started, and while still in PARK with my foot on the brake immediately jumped to over 6000, remaining there. Once again the car was shut off, restarted, and seemed to work normally. It was taken directly (and slowly) to the manufacturer's service center at my local Subaru dealership. They have not been able to re-create the problem as of this date.

I am reporting a safety issue with my 2019 Subaru Legacy that hesitates and nearly stalls when accelerating from a stop and is now undriveable due to stalling and shaking. I bought the car new from AutoNation Subaru Carlsbad in 2019. It has about 65,000 miles and I have driven it less than 2,000 miles since its last dealer visit in August 2025. Since around August 2025, the car has intermittently lost power under light acceleration from a stop or low speed, especially while pulling into or through intersections. Pressing the accelerator sometimes produces very little power, the engine feels like it may stall, and traffic behind me must brake or go around me, creating a risk of a rear‑end collision in intersections. In August 2025 I took the car to AutoNation Subaru Carlsbad and reported that the symptoms seemed like a fuel pump problem (my independent mechanic agreed). The dealer kept the car for about two weeks, experienced the hard‑starting/turn‑over issue, but did not test or replace the fuel pump. They performed other services, charged me $1,956.21, and returned the vehicle without fixing the safety issue, even though they later acknowledged the fuel pump is covered under an extended warranty. One day after picking the car up, the same hesitation and loss of power recurred in an intersection. On November 26, 2025, the car again became disabled: it cranks, briefly starts roughly, shakes, and then stalls, and will not stay running. I believe this is a defective low‑pressure fuel pump or related fuel system component, similar to known Subaru fuel pump defects that can cause stalling and loss of power. No crash or injuries yet, but there have been near‑misses due to unexpected loss of power in traffic.

Constant battery issues. I've replaced the car battery 3 times and the car seems to be suffering from "parasitic battery drain". It took a long time to diagnose the issue and I've been to the Rye Subaru dealership 2 times already and they are still trying to fix the issue. This is my daughters car and I'm constantly waiting for a phone call to have the car jump started. She works the night shift and I'm worried about her getting stranded at night.
