Anyone else getting this code? Exhaust filter full. Power decreased. See Dealership. This is the 3rd time it's been to the dealership, each time problem supposedly solved but then it repeats. Once or twice a week a code comes on that it's full, so we take it out for a drive and it clears the code, temporarily. This was happening even on long commutes to work. Now he's only 5 miles to work as opposed to 200 mile commute. So it's had highway miles as well as in town miles. Barely has 50,000 on it and has been an issue since purchase.
