This issue first ever appeared several months ago. Due to a number of parts replacements over the past several months, not certain if related or coincidental.

Seconds after coming to a complete stop at a traffic light, parking space, drive-thru, etc on about 10 different occasions I've observed a loud very slow front end groan sounding similar to grinding brakes, can be felt in the brake pedal, sometimes it will do it 3 times in a row while stopped sometimes only once. Happens in reverse too. Vehicle is NOT moving when it occurs and when it does it happen, it seems to more than once the same day or perhaps again the following day and then doesn't happen again for weeks.

 

Didn't update this but as mentioned in another thread, it turned out to be the new AC compressor fitted at the main dealer. Another new compressor fitted and problem resolved.
