Three problems related to vehicle shudder have been reported for the 2019 Subaru Ascent. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2019 Subaru Ascent based on all problems reported for the 2019 Ascent.
Car was shaking while idling/ shifting hard/ studdering while trying to shift and not shifting while going up an incline. The transmission was damaged from the slack in the cvt belt and now has to be completely replaced. Also the battery died. No doors were left open and no lights were left on. No reason to have a dead battery other than a large parasitic drain while the car is off.
Cvt appears to be faulty. While driving, rpms will jump up by 1-2k, stay at that level for a second or two, then drop down. When it drops, car will shudder or accelerate. Occassionally a screeching or grinding noise is heard. This has happened multiple times, but is not predictable. It has happened on the highway at speeds if 65 and above; and it has happened on city roads at speeds of 30. It sometimes happens multiple times in one trip; or it may go a week between events. Dealership has been unable to replicate it, says if they can't replicate it then the "best case scenario" for a diagnosis is for the transmission to fail and for us to be stranded. A internet search for "Subaru Ascent transmission problems" reveals that this is a rare problem, but seems to disproportionately affect Ascents built in August of 2018. Subaru allegedly is replacing these transmissions once problem is diagnosed, but if it's a known problem then they should replace them all proactively.
