Picked up a 2014 Summit Ecodiesel in July of 2014 and had zero complaints. It now has 5,000 km on it and I have begun to notice a vibration in the center armrest and steering wheel and what I would describe as a resonance or reverberation such that I can feel it in my ears. Most noticeable when in gear stopped at a light. If I put it in neutral it is much quieter and vibration is significantly reduced.Took it in and dealer says nothing out of the ordinary. Find that hard to believe. Anybody else have this issue? Is this normal for a diesel? Trying to figure out if it's just me or if I need to take it back.
