hey buddies ! my H3 2007, I have the following problem 5 months ago: in morning or after a long time stopping (more than 7 to 8 hours), it so, when I start the engine, it is stopped with the message on dash: service stab system, tracation failed, reduced power. so, I try starting engine after less than a minute, with pressing on the race roughly. stopping again, and trying again, all this for 15 to 20 minutes, then it works. this happens especially during the cold period here in gulf. pls. advise.

cleaned the mass air sensor and that took care of it.

Looking through the manual I noticed you can actually turn the Stability System off by it's button just above radio by pressing it for 5 seconds. Wondering if this will at least stop the reduced power while driving. I may try it if I ever have the problem again. Give me the good old days when stability systems were not included and you did not have to dismantle part of the car to get to a front signal light.
