In drive SMG would not engage...engine would just rev.Suddenly it would catch and lurch forward.Then it would clear for several miles...then reappear again.Changed battery as it was suggested by dealer that 6 yr.old battery may not power all the onboard electronics.Red "COG" is now back with a vengeance
Yesterday RED COG again, would not engage in drive or reverse and then stalled and would not restart[middle of rush hour intersection]5 minutes later it started and ran without problems.What is going on?
