I was not only pissed off but a little bit skeptical but the 13-year-old kid that was the service writer seemed confident that it wasn't covered. Didn't sound right to me either but I was passed the 36,000 mile mark. They replaced the sensor and I get back on the road and not quarter mile away things started buzzing and whistling and flashing so I went back and then they told me it must be the pump. I asked them if they were going to take the money off that I already paid for the sensor and they said they would but then they didn't when we got to the cash register. Said I already had the parts so there's nothing they were going to be able to do. Thus I am not too happy with Mountain Home Auto Ranch in Idaho.Emissions system should be covered under warranty - (Federal Reqmt on cars - not sure about HD trucks) but my DEF system was covered on my 2015 4 years later in 2019 when pump failed - was tied up for parts for a week because of lack of parts.
