The contact owns a 1998 Mercury Grand Marquis. After driving 65 mph, the contact noticed fuel leaking from the vehicle. She stated that the intake manifold cracked and she took the vehicle to the Ford dealer. The dealer informed her that there was a recall on her vehicle, but they would not honor it because it was only good for seven years. She took the vehicle to an independent dealer and paid $850 for the repair. The VIN and engine size were unknown. The current and failure mileages were 113,000. Updated 12/12/2007 the consumer stated the intake manifold was a defect that Ford refused to pay for the repairs. The consumer stated would like to be reimbursed for repairs. Updated 12/12/07

Faliure has not happened yet but has the potential with all of the other 1998 Mercury Grand Marquis. Plastic intake manifolds are defective from Ford and cause coolant loss. This can cause engine damage and possible engine failure. Recall applying to fleet vehicles should apply to private use vehicles as well. Average repair costs between 700-1000 dollars.

1. check engine light came on and remained on constantly. 2. light began to blink for a while then remain on again. The car suddenly killed in a very dangerous situation (while in the middle lane of interstate traffic with no shoulder) 3. problem was determined to be the intake manifold. We were advised that this part breaks often and in fact a recall was issued but only on police cars! the average consumer is left to fend for themselves for this expensive part. A piece of plastic costing upwards of $500 only for the part. Upon replacement we were told by our mechanic that this has been a problem part in these vehicles; and when the part was received it was discovered that Ford had changed the construction to include metal( in the area that usually breaks) in what was previously an all plastic part. We do not have the old part, and I don't suspect that the mechanic kept it either.

Problems with intake manifold being cracked. The consumer felt that the same recalls for the Crown Victoria's and thunderbird's should also apply to the Mercury Grand Marquis because they were manufactured by the same company. The intake manifold cracked and was replaced. The consumer requested reimbursement for the monies spent for repair.
