2004 F150/5.4 engine quits at low speed. Completely random, may do it several time in one day and than not again for several weeks. I have been involved in several close calls when the vehicle quit at intersections and railroad tracks. Since no odbc codes are ever set, dealer can't seem to find the problem.

Twice the engine has gone into "fail-safe" or "limp" mode; diagnosed as a "computer" glitch on a brand new 2004, less than 700 miles, Ford F150 pu; once entering the highway; once entering an intersection. When this happens, there is enough power to get you off of the road. Stopping the truck, cutting it off and back on allowed for normal use. Also excessive vibration checked 3 times, was told under investigation; no fix yet. 3 out of 4 new tires were replaced during diagnostics stating that they had "flat" spots on them.

While applying the brakes coming to a red light at an intersection, all power was lost and driver unable to stop vehicle and crashed into a dump truck. No airbags were deployed, all power was lost. Dealer checked vehicle and said that they could not find anything wrong with the vehicle. Very disturbing failure because the dealer could not find anything wrong with the vehicle to fix and that this could happen again at any time.

The emission light came on. The vehicle was taken to the dealer, and consumer was told that fuel pump was defective. The gauge went out of control. After filling the tank, the gauge read empty. The brake light wiring was inoperative, alignment was out, the vehicle had stuck in park, the right passenger door was inoperative, the speedometer read wrong, and the vehicle would die out.

2004 /F-150/SC lariot/5.4. A/C ( eatc ) not operating correctly. This vehicle has been to the Ford dealer 5 times and still no resolve. A/C will not cool properly short cycles 6/7 time per minute. The eatc (electronic air temprature control) for the A/C does not operate in Ford specs. As per Ford F-150 ws manuel, page 412-00-4 and states" it is known that a refrigerant pressure of approximately 210 kpa ( 30 psi) will yield a operating temperature of 0 (32). The A/C cycling switch controls system operation in an effort to maintain this temperature." Test results ( in F* ) at 58 / 64 % humidity max cool.( add 8/10* for reg A/C) #1. amb.70*=A/C @44* stable #2. amb.80*=A/C @51* stable #3. amb.90*=A/C @56* and unstable #4. amb.100*=A/C@62* and unstable #5. amb. 110*=A/C @70* and unstable these results were verified and reproduceable on 7 new units for comparison. Ford "hotline " says that as long as the pressures are normal the system is normal and there are no repairs or changes authorized. If this system was working as engineered by Ford specs. These readings would be 8/10* lower and operating correctly with no complaints. Ford has stated " do not return this vehicle unless there is a real problem.

I have a 2004 Ford F-150 FX4 supercab. I am experiencing two primary problems with the vehicle. First, the vibration and steering wheel "nibble". the vibration is present at nearly all speeds. It feels like the vehicle is rollong over small bumps in the road. Dealer has had vehicle twice and will have it again (3rd time) tomorrow. Claim to be able to fix the problem. The steering wheel "nibble" happens around 75-80mph and did improve slightly with rebalancing the tires. The other problem is with the A/C system. The system is not cooling the cab of the truck when the outside temp is 85 or higher. The condiction is particularly bad when the vehicle is at idle. The dealer says the system is operating at spec. I talked to a friend who has the same vehicle and he says he has the same problem and he is bringing his to the dealer to have it checked. The A/C in my friend's 1997 Ranger cools better than my new F-150.
