- If you're still in the same loaner Crosstrek, see if your dealership isn't willing to upgrade you to another loaner. I'd make it clear to them that you want/need the extra cargo room: that's why you got the Ascent in the first place, as a repeat
Subaru owner. If they are unwilling, take the case to SoA Advocacy, who should be more than willing to listen and hopefully even provide a push on your behalf.
In terms of the problem itself, remember that what seems like "a lot" online is only a very, very small fraction of the number of Ascents actually out on the roads. By being in this community -and other online social media- we're taking ourselves out of the bell-curve already. Furthermore, remember that there will be those who come to these communities specifically and only to voice their concern or even frustrations. "A lot" online really isn't, unless there's been an actual TSB or recall issued - and even then the recall may only affect a very, very
small percentage of actual vehicles on-road (i.e. the WRL-22 PCT heater bolt recall: RECALL: WRL-22 -- PTC Heater Ground Bolt
In terms of the repair, my wife's '09 Forester XT had its engine replaced with just over 4,000 miles on its odometer. The vehicle somehow managed to slip through and pass the "Stop Sale" testing at the time, and SoA warrantied the vehicle with a new longblock (my old thread on SubaruForester.org, our actual service ticket appears in post number 26: 09 Turbo engine failure
). We picked up the vehicle the day before a weekend roadtrip of 1,400-miles - she pulled as strongly as before she had the problem, and that vehicle was trouble-free for the duration of her time with us. We are a leasing family, and have leased/owned twelve Subarus since 2005 - so yes, we did return to the brand, even after this major service.
Modern production and QA/QC has made mass-produced consumer automobiles extremely, extremely reliable commodities. Small "teething issues" are not uncommon -similarly, recalls are not uncommon, due to the complexity of new vehicles- but major problems such as what you're looking at are, luckily, much less common.
Is twelve Subarus over ~18 years (add another four more, when you count my in-laws' Subarus) "a lot?"
For one family, yes, it is.
But I am also cognizant that in the big picture, my own experience with these vehicles doesn't amount to much more than anecdotal evidence.
Hope this helps!
