guys.. I reallly hope someone sees this... I bought a 2013 Jeep grand cherokee 4x4 in october and it has been great til the last week or so.. now suddenly when I am stopped at a red light it vibrates - sometimes once or twice per red light and sometimes not at all.. n sometimes its a faint vibration and sometimes its so bad I can feel ot in the steering wheel annd in the foot pedals, like a giant shudder. its makjng me craaazy and I am just past my 60, 000km warranty (ya high km for the yr). Does anyone else have this problem? And has anyone found a solution? Also how do I get replies for this? Sorry- first time user...
