NHTSA Complaint #11523457 — 2020 FREIGHTLINER SPRINTER 2500

On May 22, 2023 around 19:00 after driving my vehicle for nearly 90 minutes the vehicle no longer responded to the gas pedal being depressed by increasing acceleration. The vehicle would not go over 2,500 RPMs even with the gas pedal fully depressed. No warning were shown on the driver display or in the messaging system. The manual gear shifting did not work to raise or lower the gears while the vehicle was in this state. The vehicle display showed the vehicle in "D" for Drive and I could not change it to any other value such as D1, D2, etc.. The vehicle had almost no power and would not accelerate except for very slowly taking over 1.5 minutes to reach 55 mph. This is a SEVERELY dangerous situation as without warning my vehicle stopped responding to driver input in a reasonable fashion and thus if I was attempting to turn onto a busy road or cross a road my vehicle would not have enough acceleration to do so and could cause an accident resulting in serious death or injury. No warnings or alerts were shown on driver console. Parking assistance was turned off. Lane departure was turned off. I cycled on/off the cruise control to no avail. I evened turned the engine off and on and the problem still persisted. It wasn't until I was able to safely pull off later and power off the vehicle and wait 5 minutes that the problem went away. It is incomprehensible to me why we allow car manufacturers to override user input and commands with faulty and buggy computer software. If I press the gas pedal it should respond!
