All the heaters and grid heaters are working. I think I've got a bad batt but the dealer says they are good.... I got well over 7 years on the 05's batts...that said they are doing anything they can to cut cost and make thing last just long enough to get through warranty.... I've not noticed and odors since the recall's new SCR was installed I did have the tail pipe fall off/ out. the clamp broke and the Tec never noticed... A new clamp and all is good.... Like I said time will tell.... I'm not very happy how they blanked off the old amonia sensor wires I'll probbally seal them better at some point....
