While waiting for traffic signal to change with foot on break pedal, the suv accelerated suddenly and lurched forward and rear ended the car ahead of me! Luckily, it was a Hummer with a tire mounted on the rear door and damage occurred only to my MB. Front end has severe damage, hood buckled and headlight broken! It was a spooky experience! 'chk breakpad wear' warning light has been coming on lately when starting and I was planning to get breaks chkd. But this was a frightening experience! Is there an issue with MB ECU like this? I'm in the process of filing insurance claim.
