I started home espresso with a Breville Barista Express. That served me well for about 4 years before I got tired of its limitations, especially in regards to grind uniformity and making adjustments for different roasts (ie temp, pressure, etc.). I stopped using the built in grinder in favor of an Atom 60, which led to a massive improvement and held me over until upgrading to a Profitec Pro 600.
Until I want something plumbed in, or really want to geek out over data from a Decent, I don't see much reason to upgrade any time soon.
I had the exact same thing happen, just with a 2014 Hyundai. Only aftermarket remote starts were available when I bought the car, so that's what was installed at the dealer. Took it in for a recall repair 3 years later and the remote start was broken when I picked the car up.
Contacted multiple dealerships and they wouldn't touch it since it's aftermarket (despite being installed at a dealer). The shop that did the recall repair flat out said I couldn't prove it was their work that broke it so they're not responsible. My only option was to take it to a local shop that does that type of work. Audio install and aftermarket mod shops were the best bet.
