“My Mercedes Benz GLA250 has a faulty rear differential and began shuddering and driving poorly when it had 44K miles on it. This is a very premature failure as diagnosed by two repair shops and is happening to thousands of this model Mercedes Benz. The damage can be catastrophic if continued to be driven as the differential metal continues to deteriorate and possibly have metal shavings travel into the engine. I was told initially by Mercedes Benz it was bad tires! I replaced the tires and the shuddering became worse. …”
