Car sometimes refuses to start. Hyundai has had it a month waiting for it to fail to start. Their diagnosis is a failed engine control module (cost for part and service, approximately 1,000). I cannot find engine control module replacement among the listings on Repair Pal.

The ECM is not a common part for replacment, and does not appear in the Estimator tool. The price is not terribly out of line, depending on the vehicle. I think your car warrants more inspection and a second opinion before spending that money possibly needlessly.
