Powertrain Malfunction

[IRE]

I have had my F-150 Lightning for 7 weeks and have clocked 3,600 miles.

While driving yesterday, a warning came up on the dashboard saying to take the truck in for service and power dropped such that one could only crawl along. I stopped at the first light. Powered off and on. Power came back but the warning light (orange spanner) persisted so I gingerly drove home.

My Ford App on my phone declared that there has been a Powertrain Malfunction / Reduced Power. The warning illuminates when the system has detected a powertrain or a four-wheel drive fault which means I need to contact the dealer ASAP.

Has anyone seen this?

My lightning did the same thing . I didn’t drive it for a few days and when I jumped back in the truck it was cleared and has been fine ever since.

This happened to mine and mine also cleared on it’s own - I made an appointment with dealer anyway and they advised there was a Ford Power Up that was in the process of installing and that was the likely cause.

The fault cleared overnight. I still took it into the Ford dealer where I bought it. They reported a number of other alarms in the system, test drove it for 30 miles for two days. Fault did not return and they declared that it was good to go.

Looks like consumers are testing Ford's hardware and software. Hopefully this will not happen again.

Incidentally, I was surprised to see that this is a very common problem reported on a number of F-150 Lightning forums.

 

[ICED Lightning]

I think we may start to realize that, like the 'dummy lights' that happen frequently on ICE vehicles, like the scorned 'check engine' light, are rarely dangerous, urgent, or anything of real relevance to the driver.... continue on.
I don't think that there is anything, as a driver, that you can do, that would somehow 'harm' the truck, if you simply continue pushing the GO pedal...


hopefully my Lightning's 'check engine' light will not come on simply because I forgot to turn the gas cap enough times : )
