Very finicky car

Like many German cars, this has its quirks. The navigation is tough to get used to, but that's not what's most curious about this car: at elevation about 10,000 feet, the nav shuts off! It displays a warning and becomes inoperable. Mercedes says it affects so few people that they won't fix it. So if you drive in the mountains a lot (we live in Colorado) and want to use this car in high elevations, keep this in mind. As importantly, keep in mind that Mercedes refuses to spend the time reprogramming the nav systems. Maybe they outsourced that part to Japan...

Complete transmission failure including torque converter at 74k 9k repair bill with only 1 year warranty through Mercedes dealership. Subsequently traded it in for a Lexus.

5000 miles update

Well it time for an update on my ML550. I put on 6,000 miles and so far not much problem to report. I had to make one stop to the dealer to date and that was for a recall notice I receive to fix some hydraulic problem and tail light seal. The truck was drop off in the morning and i picked it up about three hours later. some noticeable comments: 1) there is a click noise in the cold when you first start the car. 2) With the window down a loud noise is heard when switching from park to drive or reverse. The dealer said this is normal and is due to the large solonoid. 3) The radio went off but no display came on. The radio came back on after the vichele was turn off and back again.

I bought this car 11/29/08 with 10 miles.This is the best car I have driven to date. The ride is smooth, excellent for long trips. Control and nav are relatively easy to use, not complex as some indicated. This is my first MB. I have 1200 miles on it so far so its too early to assess its reliability. I absolutely love this car so far.
