trunk will not open

I have not had this problem fixed. I was wondering if anyone out there had the same problem. I can't get the trunk to open using the key or the remote.

What a crap. My 2005 MB S430 has 81K. I have had nothing but problems, one after the other. Instrument cluster and command & control had to be replaced three times. Transmission controller module needed to be replaced. Crankshaft sensor, fuel pump, AC blower motor and regulator, windshield wiper motor, etc. all needed to be replaced. Now the temp, clock and gear shift indicator went dead in the...
I have a 2005 MB S 430, Granted it stays in a heated garage and is cleaned all the time.. I have had no problems with this car at all 130,000 miles. Just brakes and tires, reg oil changes. The only part I have replaced is a heater control valve in the cowl area, $175.00. no big deal. The car is adult driven and yes I did buy this car new. Going on a trip this summer and I am planning on replaci...
Not what it should be. Over rated. Too costly for every little service. Floor mats are not good....they should be attached to the floor so they do not move. The AC is not very strong ( I live in Flporida) takes too long to cool the cab. I do not like the windshield wipers, with it auto wipe on rainy days. There are a lot more problems........... for the price ......it sucks.
