It threw a code for a reason. It's good it went off but if continues to happen it might be worth scheduling an appoint at the dealer just in case. They can use a scanner to see what the code was for and if there is an issue it will be fixed under warranty.

Did you hit this cow before the light came on?

Yes ,of course thank you!! I will scan it and have it checked was happy it cycled.. Blow it up under warranty is always the plan.

If it was steady on, most likely an emissions issue. You say you really stepped on it to enter freeway, computer saw abysmal gas mileage and threw the appropiate code.

If it comes on and starts blinking, pull over immediately. There is something seriously wrong.

My older sister used to use the “ so and so was having a cow” reference all the time.

the same thing happened to me. I wasn’t going full throttle but I was pushing it as I was entering a freeway going uphill and all of a sudden it came on. I wonder what the issue is.

I had the check engine light around 1800 miles as well. I got P0811 code on OBD reader and it is tied to Transmission slippage. I went to dealership and they reset the code. Asked me to come back when the Check engine light comes back again for them to diagnose the issue

It's no big deal it has not come on again and I've done the same thing it's all the sensors and all the engine and all the CVT learning to work together. Truck has been perfect since I love it.

I have a hybrid Lariat FE. @~2500 miles now.

I had the same code P0811 on 2/24. I let the car sit for a little over a day and drove it a short trip and the light went off. I took it to the dealer yesterday and they still have it. Still pending diagnosis.
They did say it could be a bad clutch, flywheel, clutch damper, or bad sensor. They wanted more time w/ it.

While the light was on I did experience strange brake issues. If your stopped at a red light and traffic moves forward and your foot is on the brake keeping the trucks topped and you let up a little and creep forward to follow traffic to get the truck to stop again the pedal goes dead about 2-3x the force you had it prior to hold the truck still. Its not like the pedal goes dead like air in the lines. Once the CEL went off this seemed to go away. I noticed this pretty heavily for the first 2400 miles while at red lights or drive throughs or parking in my garage where I have inches of clearance in my tight garage.

Still getting great MPG and really no other driving issues.

Clutch??

Clutch??

Technically there is a fixed clutch pack between the engine flywheel and input of the transmission as a fail safe if there's a power/load mismatch in either direction so things don't break. Presumably there's some function monitoring ICE engine RPM to trans input speed and a discrepancy there is flagging the CEL.

I have the same exact issue with braking and check engine light as well.

I have been averaging between 28-31 on Hybrid XLT

Seems to have gone away once the CEL went off on its own. Dealer just cleared it and sent me on my way. Hopefully it wont come back.

Your MPG is low, maybe its cause your in the COLD climates? I am getting tank avg 37.8 and when its under 50mph 45mpg

Mine has never come back on, only came on the one time. Very pleased with my hybrid! I'm glad it came on that means it works, and I'm glad it cleared itself. If not of course I would have taken it into a dealership.
