Two problems related to check engine light on have been reported for the 1997 Mercury Sable. The most recently reported issues are listed below.
At about 100,000 easy highway miles, we had to replace the torque converter, then the entire transmission, plus for the last two years minor engine repairs to the tune of about $350 every other month, the window won't go down anymore, and now--4 months after the transmission replacement--we have lost overdrive and the engine light is on, again! we have never had a car with this many problems, and will never buy a Ford/Mercury anything again. Our suburban was more reliable.
While traveling on the highway without prior warning. The engine light appear on the dashboard and the vehicle will stall. The dealership is aware of the problem. Nlm.
