but recently, my ML500 (2003, with a hair under 42k miles) shuts off. again.

this is not the first time this happened. they have replaced, engine mounts, bushings, key&ignition, tranny mounts, and a bunch of other crap.

what happened the first few times, was...

1. driving normally, no heavy throttle. boom. car shuts off. no power, no brakes no nothing. (bought it in, "fixed" replaced some crap and out)

2. driving normally, all of a sudden, car shuts off, but WITH power, all eletronics work, but RPM is @ zero, everything shown at cluster is at zero. and the car feels like it just shut off. (bought it in, replaced alota crap, even the cluster)

3. driving heavy throttle, on the highway, and all of a sudden bam. funny rpm, like its spazzing. then it shut off. (bought it in, *****ed at the SA, and called mbusa, they said they'll fix it bla bla bla, came out, wow no problems for abt....4 months. until recently)

RECENT, about 2 weeks total.

Driving in city traffic, so think about 40-50mph max. so all of a sudden, the RPM quickly drops, down to 1k rpm. floor it, it'll jump up to 1.2k rpm at MAX, and grandma walks faster than the car. seriously, car doesnt move. at all.

so...OK, shut if off for 5 mins. checked everything, oil is fine, not over heating, NOTHING stuck in the intake, bla bla bla, turned it back on. runs fine.

this happened a few times within a 2 week period. so I have made an appointment with MB-MANHATTAN for earliest, FEB 19th, 2007.

BUT BUT BUT....heres the deal. what happened today. same situation, RPM drop, i let go of the throttle, car seems slug-ish, so i heavied the throttle a bit, and it hits...1500rpm MAX. car DOESNT move, infact, its slowing down. shifting down on the touch shift, moves abt 100rpm more down to "optimal gear" and car slowed down, until it seriously dead stopped. I shut the car off, for 5 mins, do the routine checkup, not over heating, oils right, etc. turned it back on, engine rpm jumps. normal startup, abt...what? 3-4k rpm? then when the idle went down to 500. check engine light came on. and whats funny. even if u floor the car at idle, it jumps up to 1500rpm max.

any help? thanks in advanced

The solution was simple - get rid of it, and I recommend that to you. Once past warranty, you'll have to deal with more frustrations, especially financially, if you keep having the same issues you currently have. Keep in mind that the warranty on whatever work is performed on the truck now expires with the 4/50 OEM warranty. So, theoretically, if you replce a component in warranty a day before your warranty expires and that component fails two days later, guess what???? It's on your dime. Yes, I know becasue I went through this. Unless you can work out something wth your SA regarding post warranty repairs, get rid of it. Way too much headache!!!
