Well That Was Weird....

I woke up this morning, warmed my truck up as I was doing my pretrip. I hit the highway and got up to speed. Then all of the sudden every warning light and buzzer went off in the truck. I lost power and pulled onto the shoulder. Restarted the truck and everything was fine, now the check engine light is on though. Do I contact my FM or what?

I would. You dont want to be stranded on the side of the road and it is better to get it taken care of right away, Generally that problem doesnt go away and can pop up at any time.

Just weird, it’s a brand new truck.

Its not all that uncommon for a new truck to have issues, especially when it comes to the electrical side of things. When I worked for PFG we had a couple freightliners that were maybe 6 months old with probably 40k miles on them. Both of those trucks were frequently being sent to the dealership for all the lights coming on and not allowing you to shift out of neutral. The other 2 trucks we had were 5 years old with 400k on them and ran quite well. Each time they were sent to the dealership we lost them for 3 to 4 weeks. It makes me chuckle a little bit when somebody thinks buying or leasing a brand new rig will prevent them from breakdowns. I agree that contacting your FM or road assist would be best. They will be able to tell you better what to do. I'm sure sometime soon theyll route you to a terminal or shop to have it checked out.

Guys I THINK I know exactly what I did wrong and I am super embarrassed. Such a noob mistake, I forgot to put the gas cap back on

That may cause the engine light, but it shouldn't cause the other problems.

My dad has been working on trucks for 30 years and he says it's not uncommon for new trucks to have electrical issues. He's even had some that needed to be rewired right out of the factory.

Sounds like you picked up an electrical gremlin overnight while parked.

These do happen in the trucks, brand new or older life, from time to time. I've had erroneous warnings on the dash in every truck I've driven. Some were a few seconds, while others lasted for more than a week. About the only thing you can check is the radiator fluid level and cap, the air filter, the engine oil, the fuses, the power steering gearbox fluid, DEF tank, the fuel water filter, and the fuel. Most everything else I can think of is going to be either electrical and/or need a mechanic.

I would call your maintenance or breakdown phone and listen to their solution. Other than that, just keep an eye on all the gauges, watch the mirrors for prolonged excessive exhaust smoke, and listen to the motor while at different speeds and RPMs. It's probably nothing.

When you first turn the key to the on position stop there and let the electrical system cycle through. Lights flash, stuff beeps and some models the dials in the guages will move. Once it all settles then start the truck. It can help with the gremlins.

I would call breakdown and report the problem and notify your FM as well. These new trucks have miles of wiring in them and the electrical systems are crazy. When I worked for Werner Enterprises they issued me a brand new freightliner and it stopped regenerating in after I had it two weeks. I had to get towed to a dealer to get it fixed. Techs where not surprised and went to do a forced regen. The tech walked away to use the bathroom; and whie he was gone, it caught on fire and burned down to the frame. I always take electrical issues seriously form then on.

Whenever something Electrical goes weird the shop always tells me to cycle the key 5 times as that well reset the computers. So far it's worked every time .
