I have never seen an electrolytic capacitor fail in an automotive context, and I've owned my fair share of capacitor plague-era vehicles. I'd imagine it's a combination of preferring other types of capacitor for that environment and not buying the cheapest shit they can find in the markets that day like Dell did.
