My husband and I purchased a 2011 Winnebago View Profile. It has 25,000 miles on it and we have had one problem after another with the check engine light, air conditioning, air bags (recall) .... Recently the check engine light came on again and we had to have the motorhome towed (told my Mercedes complimentary tow through roadside assistance) to the nearest dealership. We did that. Dealer informed us that NOx sensors failed. I did some research and there have been 5 recalls on the NOx sensors with Mercedes. Cost just to replace the NOx sensors was over $2000 and was told could then be problems discovered with the catalytic convertor. Filed a claim with Mercedes of North America. Was finally able to speak to a Executive Referral Manager a week later and he offered no assistance whatsoever. He said because it was out of warranty they wouldn't pay for any repairs. This vehicle has had one problem after another and we have paid for all the repairs. Finally reached a point where enough is enough. This is a known problem with the NOx sensors but Mercedes won't admit that or take responsibility for fixing it. I would never, ever buy from this company again. Worst customer service ever.
