I got a bad deal on my 2012 550i xDrive
 Purchased the car from BMW Schomp, Highlands Ranch, Colorado on 8/25/2012 (NEW). In Nov 2012 (1,985 miles), replaced a faulty passenger seat memory chip. In Dec 2013 (8,014 miles), recharged battery due to excessive battery discharge. In Jan 2014 (8,214 miles), replaced battery with 92-amp battery due to repeated battery excessive discharge (which Schomp mechanics kept defending the old battery and the reasons for the excessive discharge). In Sep 2015 (19,381 miles), fixed faulty trunk light, replaced fuel delivery line, VAC pump, injectors. In Nov 2015 (21,549 miles), replaced passenger seat sensor/detector. In Jan 2016 (22,393 miles), replaced old battery with a bigger one (105-amp battery) due to repeated battery excessive discharge. In 2017 switched from Schomp's shop to "BMW of Denver Downtown" shop. In May 2017 (35,546 miles), experienced "Drive Train Malfunction" and replaced failed low pressure sensor. In Aug 2017 (37,096 miles) experienced repeated "Drive Train Malfunction" and replaced failed low pressure fuel pump. Also, experienced repeated "passenger seat sensor/detector" failure which "BMW of Denver Downtown" refused to fix under warranty. I had to pay for all 2017 problems since the car was out of warranty, which costed a lot.
