What's the rest of the fleet like? Power train good (so far) but stupid stuff - like mechanical mechanism for passenger window replaced at 45000 miles, wheel bearings replaced at 48000 miles, brake sensors corroded and replaced 46000 - all out of warranty, of course. Trunk developed leak at 43000. I buy one owner-off lease vehicles with about 25000 miles on them. Drove Lincoln Continentals for 10 years, bought extended warranties - never once used them - cars each died after 175000 miles. This car would cost a mint to drive 175000 miles. Very disappointing for quality and reliability. Cadillac, you've got a long way to go to be perceived as a quality vehicle.
Quality and reliability of mechanical and electronic components.
