While traveling about 40 MPH in traffic without any warning, my check engine light flashed on immediately followed by the heat gauge maxing out and a buzzing noise began sounding. What appeared to be smoke was pouring out between my hood and cowling. I managed to stop the car and lifted the hood. Antifreeze smell was strong, water was shooting into my alternator and the engine was excessively hot. I had the car towed to a reliable garage and they determined that the intake manifold had split open, but the "smoke" was actually steam and no fire had ensued. Later that day, the mechanic called and said a new manifold would cost about $400, and about another $400 in labor. The final bill was actually $820 and $60 for towing. Upon notification that a newly designed manifold was now being sold, I became suspicious about why ford would do that. I checked ford and was told "my VIN# was not part of any recall, period! After checking this the federal safety agency site however, I found several interesting facts. There were about 300 complaints of this same rupture - I believe the number of people not reporting this problem were several times higher. I also found out that all 4.6 liter engines at least in 1997 and 1998 had the same problem. I also discovered that ford had "quietly" and I suspect "illegally" did a selected recall on fleet vehicles and police vehicles without telling anyone else. Why would ford be allowed to selectively correct an engineering defect. Is my life worth any less than a fleet car driver? I called fords consumer hotline at 1‑800‑392‑3673 and spoke with a rep named vicky. She had the audacity to say my VIN# had no recall and she never heard of this problem, furthermore that she had no access to this site nor was aware of it. If ever a company needed reprimanded, ford does.

Car was brought to dealer under warranty numerous times with complaint of low antifreeze in radiator and the faint smell of antifreeze towards the front of car, after driving the car. Dealer claims he could not find leak under warranty, but found it soon after warranty period. Dealer said part of new radiator cost would be covered but still charged $100.00 for repair. I reluctantly had to pay it to get my car. I have purchased 2 cars at the dealer and so has friends and relatives. Dealer did not stand behind warranty totally since the problem was presented at least twice during warranty. Dealer did not fully comply with 3 year ford warranty in my opinion. Dealer did not react to my complaint after the repair. I will not buy or recommend purchase of another new vehicle there again.
