The 2020 Subaru Ascent has had a recall notice for nearly six months now (Manufacturer Recall NumberWRK21 NHTSA Recall Number21V955000). I experience a low frequency sound accompanied by rapid vibration lasting only a second when reapplying acceleration after a brief pause in acceleration. This occurs very inconsistently and not yet something replicable at the dealership. Subaru states they are working on a solution...The local service manager states they will do nothing unless a service light appears on the dash and that the remedy is likely replacement of transmission and they are not going to do that. We occasionally travel in mountain passes. This recall seems serious. Does NHTSA have any control over Subaru to force them to take the recall seriously? Do owners have to be injured or die for appropriate remedy?

Something in car drains battery frequently not while the vehicle is running but after it’s been off for a few hours when no lights have been left on, Subaru dealership refuses to admit there’s a problem. This leaves me exposed to being stuck in unsafe situations with a dead battery. No warnings ever come on to alert me the battery is draining. Transmission frequently slips and stutters when accelerating to higher speeds like when trying to transition onto the interstate. Subaru also denies this problem. They fixed the transmission clutch but that did not help.

I was crossing a four lane road going 20mph when there was a loud noise, which sounded like my transmission, then I could not accelerate my car. Thankfully I was able to coast across the road without being hit by another car to a safe parking spot. My check engine light, check transmission, and check eyesight lights all went on. (Later MySubaru only sent me an email saying my engine and eye sight lights were on). I was unable to put my car in reverse but could put it into park. My lights, radio and AC stayed on until I turned my car off. A tow truck came and towed my car to the nearest Subaru dealership (which was not my dealership since I was away on vacation). There are less than 20,000 miles on my car, my transmission failing is unacceptable and thankfully did not happen on a highway which I drive on a lot. The dealership confirmed it is indeed a transmission issue and Subaru agreed to tow it to my dealership near my house.
