NHTSA Complaint #11488160 — 2015 BMW X1

The engine coolant thermostat limited warranty for defects in materials or workmanship. The vehicle currently has 60,128 miles. The vehicle's "service engine soon", warning light began appearing intermittently and now it is constantly on. The car has a stored code (P0597) Thermostat Heater Control Circuit/Open.This vehicle has a current technical service bulletin for a defective thermostat for this model year; however, the VIN number is not included. This should be investigated further as this Technical service bulletin(SI B01 01 16) suggests that PRODUCTION date is NOT the sole determinate, but rather, the entire model year is just as imperative!! The local BMW dealership is refusing to repair the vehicle despite having premature failure with the thermostat heater control circuit/open for this model year vehicle and with a currently illuminated warning light and code (P0597). Although the technical service bulletin states that the model year & model numbers are both covered, the bulletin further states: 1) ."Note: The MY 2015 vehicles produced up to and including January 31, 2015 (as applicable) have been added to this bulletin December 2017"; and, 2) "Please do not use a vehicle’s production date as the sole determinate for this coverage, the vehicle’s “model year” is also an important determinate."
