Not 5 star! None actually.
A complaint was submitted today with California Bureau of Automotive Repair to report California State Law Emissions Control Warranty violations against SLO BMW.
Subject vehicle: 2016 BMW X3 28d. (diesel).
Vehicle Mileage is 68,000 miles.
California Emissions Warranty - 7 years / 70,000 miles applies.
My original Warranty Booklet that came with this vehicle specifically indicates that the failure of the "SCR Metering Module" is covered under the 70,000 mile emissions warranty. The Selective Catalytic Reduction (SCR) module is a critical emissions control component that injects Diesel Exhaust Fluid (DEF) in the exhaust specifically for emissions control purposes. This is what prevents all diesel cars and trucks from blowing out black smoke. SLO BMW Service Dept diagnosed that the Diesel Exhaust Fluid (DEF) injection line broke off at the SCR metering module and the metering module needed to be replaced. They quoted $750 to fix it and SLO BMW refused to accept that this is a warrantied part listed in my warranty booklet. I had to pay $199 (diagnostic ransom fee) to get my car back unrepaired.
I contacted BMW of North America Customer Service and they also refused to honor their warranty. No explanations provided. Just plain NO.
This is a clear violation of California Emissions Law. From the California Code of Regulations, Section 13, Division 3, Chapter 1 Article 6 section 2039 which states: "For 7 years or 70,000 miles (or a longer period of time or mileage, optional) (Whichever first occurs); If an emission-related part listed in this warranty booklet specially noted with coverage for 7 years or 70,000 miles is defective, the part will be repaired or replaced.
