I have a 2004 mercedes benz c230. The alarm sounds continuously while driving down the road. When this happens, the key will not disable it. The dealership says there is not a problem with mercedes but I seem to find lots of complaints on internet blogs regarding other customers having the same problem. What is our right as a consumer? Should there be a recall to get this corrected?
Tl*the contact owns a 2004 mercedes benz c230. The contact stated that the engine oil was leaking onto the o2 sensor. The o2 sensors were placed august 2009 by the dealer; the problem was not corrected. The engine oil began leaking on the sensors again so the vehicle was taken back to the dealer where the contact was informed that the camshaft, wiring harness and o2 sensors needed to be replaced. The contact called the manufacturer who offered no assistance. The vehicle had not been repaired.
