The coolant thermostat was broken and gave two check engine codes P0128 and P0128P. AC was not functioning when the thermostat was not working, which can be dangerous in summer. It is also a very common problem with Cadillac XT5 and GMC Acadia.
The tread is separating from the tire in chunks. Never seen this in a 21000 mile factory Michelin tire let alone any other tire before. It exposes the core of the tire which is a safety hazard. Called Michelin and they were only concerned about the warrantee, not the safety.
Passenger side seat bolts attaching seat to frame loosened and seat began to rock
Check engine light (power reduced steering drive safely) notice came on. Code reads P0128, coolant below thermostat regulating temperature. This is an on going issue with Cadillac.

Then you are left with no choice but to get repaired at the dealer only to be ripped off. 180 for d...
