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.
On three separate occasions the vehicle has stalled while driving on the highway. *nm each time this happened the vehicle could not be restarted and had to be towed to the nearest garage. The dealer informed the consumer that service bulletin 12950 as issued in 1999 identifying a fix for this problem. Since the consumer's vehicle was no longer under warranty he was forced to pay for the repair.
While driving vehicle stalled. Consumer used a starter battery kit to restart the vehicle or contacted aaa to have the vehicle towed. The aaa representative indicated that the stalling may be due to engine motor failure. Dealership and sears retail store performed a diagnostic test, but no failure code was found. Also , the battery and air bag warning light came on. This failure almost caused rear end collision.*ak owner is an ex philadelphia eagle football player named curtis bunch-black.
Intermittently while driving at highway speed vehicle stalled. This caused the loss of steering and the brakes. Vehicle was towed to the dealership, they charged $750.00, and problem recurred.
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. *mr 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.
Consumer was experiencing problems with the cooling system but wasn't included in the recall. *ph the consumer had to anti-freeze to the vehicle on a continuous basis. The consumer was then informed there was a defect with the 4.6l v8 engines. The manufacturer used carbon fiber intake manifolds on the engines. Due to the heat, the carbon fiber intake would crack which caused a lost of coolant. The consumer told there was a recall, but on;y for police vehicle's.
Ltr fm louis hettinger(ky) owner of a 1998 mercury grand marquis 4-door vehicle question if vehicle should be recalled because of fast idle. *mr the iac valve was replaced on the vehicle but did not help the problem. The service dealer stated that there was nothing else they could do to resolve the issue. There were other consumers who experienced the same problem. (there was a fast idle upon start up and the vehicle would slow down at short notice. When the problem occurred, there was no way to control the vehicle) *scc
While driving at 50mph on flat surface and with no warning vehicle shut off.
