Huh? Pacificas are everywhere, especially since they also have the only PHEV minivan in the US. In the PHEV Pacifica FB group I'm in (I do own one, so I am a bit biased here), many people have Pacificas alongside Teslas and other EVs. But even the gas Pacificas are everywhere, including "upscale suburban driveways".
Though your point does still stand about FCA/Stellantis' reputation: we had to get over their our perception of them when we got ours, and I would never consider any of their other vehicles. But our Pacifica has been a really great van. I'm just amused that you picked the one vehicle in their entire lineup that doesn't prove your point.
You're right about the PHEV thing attracting a lot of people who otherwise would never own a Chrysler. Checking "just the right boxes" is something FCA is really good at with their more niche vehicles. The high horsepower Charger/Challenger/Cherokee and the Jeep Wrangler are amazingly good at creating a way for the married couple who can't agree on what vehicle want to both leave with enough of their boxes checked.
The reputation hasn't stopped FCA from selling to this market. Wranglers and Grand Cherokees are pretty common too, as well as the rare Hellcat.
On one hand you have FCA (I'm sorry, Stellantis) which leans into its not so positive reputation and does just fine.
The other hand you have Toyota who spend the 90s and 00s digging a goodwill moat in the minds of premium consumers.
Both approaches work but for different demographics. You'll never see a 4Runner with a magnetic company sticker sitting in an industrial parking lot or in less well off part of town and you'll never see a Pacifica in an upscale suburban driveway.
