Thanks for your honest, thoughtful response. I’m guessing I could get it working again on my own. I’ve just never felt so disregarded by a dealership/manufacturer is all, I guess. Especially a “luxury” brand.Honestly? With yourself. You bought a used car without a warranty, right? A complicated one at that. After a car is out of warranty and especially if you didn't buy it new no auto manufacturer is going to waste much time with you. Even if you threaten to never buy another of their brand. Troubleshooting my friend. The liftgate does not seem to be super complicated, mainly switches, a control board and a motor. Ask questions, work your way through it. Solve your problem. You seem pretty mechanically inclined, get after it.
