R350- Brakes, Hatchback and Seatbelt problems

[mummy3]

Just purchased my R350 3 months ago. Really like my car, however,... 3 small problems... My back hatch sometimes sticks...the dealer said the on-board computer showed no problem with the back hatch yet occasionally it still sticks. The brakes have begun to squeal when coming to a stop and just today my seatbelt unlocked as I was driving and went flying over my left shoulder. There was no way I hit it, I wasn't moving around, and both hands were on the wheel... and a passenger in the back seat saw it happen and was as shocked as I was. It had been securely fastened and the "seat belt indicator" was not on .. I had been driving for about 30 minutes before it released suddenly and on it's own. I was not turning but I had taken my foot off the accelerator to slow down a bit. I could not make it happen again after returning home. Has anyone else had such problems?

Hello you have to confirm the diagnosis tool your dealer uses.......it's has to be only star diagnosis. If not please go ex where for the solutions okay, may be a workshop that well equipped.

I have come this types of problems before. The brakes need to be looked after. It is good do refer a mechanic for a complete servicing. Have you bought the car direct from show room or a resale? Due to friction or decrease in brake fluid, brakes generally wear out. Sometimes it needs to be replaced. Regarding seat belt, how many times it happened while driving? If it is once, it might be an not properly locked error. If it is more, try getting a car mechanic.
