NHTSA Complaint #11700391 — 2016 MINI COOPER CONVERTIBLE

The Environmental Air Catalyst (EAC) Sensor on my 2016 MINI failed two years ago when I had only 25,000 miles on the car. (The car now has 30,200 miles on it; I do not drive it very much). NHTSA worked with MINI/BMW several years ago, and MINI extended a limited warranty for this sensor to 15 years/150,000 miles, but only for Cooper "S" models. Mine is not an "S". See Recall "S1 M01 05 20" The S has a BMW "B46M PZEV/SULEV " engine, which is covered by the extended warranty. My car - not the "S" model - has the BMW "B36M" engine. This is not covered by the extended warranty noted above. I have gone online and saw lots of complaints, as this appears to be a very common problem. A MINI dealer in Richmond, VA told me the same thing: the sensor fails, and you have to replace the entire radiator because the sensor is attached to it. I was quoted more than $2,000 to fix this problem. It seems to me that this defect is as common in the non "S" MINI Cooper's as it is in the "S" versions, and that MINI should extend the same warranty to vehicles with the B36M engines. Can you help?
