My brand new F150 2021 had a powertrain malfunction with power totally reduced. I had no ability to accelerate. I had to glide over to the side of the road. I restarted the car. It reset, i went to accelerate and again i had an error code and my car froze. I was able to restart again and drive over to my Ford dealership i purchased it from at 15 miles per hour. The problem was reproduced once and confirmed by the dealer. The dealer has contacted Ford and was told they have never seen that error code for a F150. The GM of Ford here in Montana told me if they cant reproduce the problem again, i can have the truck back. This truck is 3 weeks old. I am terrified.

F-150

  • miles
I purchased the truck early 2021. After about 6500 miles, upon starting the vehicle a warning message to the effect of "Oil Level Low, Add Oil" appeared. After manually checking my oil dipstick, I found the oil level to be below the safe oil line. I promptly took the truck to the Ford Dealership in which I purchased it. The service technician informed me of one other case he has personally experienced where the PCV system was defective, allowing an excessive amount of oil to be consumed. Ford was unable to receive my vehicle for service for 1-2 weeks due to a full service schedule. It was at this point I attempted to go to a 3rd party vendor for an oil change. That vendor checked my oil level and confirmed the reading was below the safe oil line. They advised I return to Ford. Concern for my safety and the continued safe operation of the vehicle, I requested the 3rd party vendor to add a quart of oil. In the end, it took 2 quarts of oil to return the oil level to a safe operating zone. I then promptly returned to Ford and spoke to the service department manager. They will accomplish and oil change and return the vehicle to me to perform an oil consumption test over the course of approximately 1,000-1,500 miles, before returning to Ford for further evaluation.
