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.
