This ^. I had to replace a dead battery in my truck a few weeks ago, and it's been all frigged up ever since - apparently all the engine tuning resets if power is disconnected.
I've tried to get the dealership to disable the door auto-locking (get above 5 mph, doors lock) "feature" half a dozen times, and I've given up, since they disable it in the software and it's turned back on before I leave the parking lot.
ABS brakes are awful, and down-right dangerous if you are not expecting their flaky behavior, and rather want them to perform in a predictable and consistent way. It's terrifying driving an ABS vehicle on icy roads.
Who hasn't had a largely irrelevant, but very expensive, sensor burn out and trip a buggy corner case in the engine firmware?
I realize I sound like a Luddite, but my favorite vehicle so far is still my first, which was a bare-bones, rusty 1985 F-150 with a four-speed manual and a straight six. It's still on the road, with over 300,000 miles on it, although it has become something of a truck of Theseus, aside from the frame and tranny. You can tear the whole thing down and put it back together with a pretty basic set of mechanics tools. It wasn't perfect - starters and solenoids tended to go bad, and mileage was a tad worse than the current models - but it's simple, so that when things go sideways, you patch up the one component that's broken, and trundle onward.
