“My car was not running correctly one day, so I took it to my mechanic and he found anti-freeze in the cylinders. He said that the anti-freeze blew through passage on intake manifold into the pistons, and I had to replaced the entire motor and the intake which cost me $3400.00 enable to fix. I can not understand why they used a plastic part on the motor.”
NHTSA complaint #10143109, filed 2005-11, 82,160 miles“Plastic intake manifold on a 1996 ford Grand Marquis 4.6 liter v-8. Apparently there was some settlement offer from ford to replace this part with an aluminum intake however due to the car not being driven much, 70,000 miles in 12 years the intake manifold did not fail until recently. I would like to know what options I have in fixing this part and possible reimbursement of the $800 or more it will cost me to fix it.”
NHTSA complaint #10251873, filed 2008-12, 70,000 miles“My car (1996 Mercury Grand Marquis) developed a crack in the intake manifold leading to complete loss of coolant and overheating while traveling through wyoming. It was then towed to a small town repair shop, where this problem was brought to my attention, and that many cars had a recall for this. Unfortunately, for civilian cars there is no recall which LED to a repair cost of $1132.00.”
