Stabilitrack - 2nd time occurring since purchased vehicle new in 2009. Error message - stabilitrack needs maintenance, then engine powers down. First time, fixed under warranty approximately 3-4 years ago. Problem back Jan 2014 - at first ice and snow packed under vehicle; once removed/thawed out, error light went out for a few days. Problem back on consistent basis now if hit uneven road and/or ice - more days have problem than not, now days. Dealer advised would have to fix/replace entire stabilitrack which, part alone was approx $500+. Annoyed; unemployed with no money to repair.
