One problem related to front air bag sensor control has been reported for the 2002 Mercury Grand Marquis. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2002 Mercury Grand Marquis based on all problems reported for the 2002 Grand Marquis.
Air bags are rendered inoperative by failure of a sensor in the driver's side seat belt pretensioner. Flashes code 3-4. Part in question is oem number 2w7z54611b09aaa. Ford advises that part is discontinued, no replacement parts available. No other explanation. This leaves two choices: drive without airbag protection or replace vehicle. This car has less than 16,000 miles on it and need not be replaced. How can a safety critical item be discontinued in less than 6 years. This part is required to be replaced in the event of an airbag deployment and, as in my case, when the sensor failed.
