My new, 18 months old F150 has had six engine lights come on . . . . the first four were resets until they finally fixed it by taking the engine apart and replacing a knock sensor that was bad.... That's a really bad feeling for an owner of a new truck with less than 9000 miles . . . who takes a new engine apart at 9000 miles?!?! Six months later and now another light comes on, Ford dealer wanted $75 to plug the machine in and tell me the problem ... O'Reily Auto Parts did it for free / / / P2450 code says an evap valve is open on the gas tank . . . WTF on a new truck with less than 34,000 miles . . . I have had it less than two years! 18 months and I'm getting this horseshit . . . I've owned over dozen Fords, I am an old man who drives like an old man, ... OK sometimes I hit 80mph on the freeways... But that's no big deal, I never had any issues with my Fords in the past, but this 2018 XLT 4X4 seems to be a lemon.

The service writer at Ford said he couldn't get to me until next week and it won't hurt to drive the truck . . . however, he suggested I add some high octane additive to my gas tank and drive fast on the highway for half an hour or so. I nuked my gas tank with high octane gas and the additive and hit the road. I returned home an hour later parked the truck and shut it off. I got in the pickup the next day and the light was off! I went to the local auto parts store for another reading and my friend there said my engine was operating normally. From now on I'm buying high octane and adding the engine boost additive at my HEB gas pumps.
