Hi All,
I have a deposit on this unit but it has engine issues. When I test drove it twice I drove it with the throttle to the floor most of the time. It would shift at 1200 rpm so it goes through the gears very quickly. Also, it would never down shift at all even once I eventually got to highways speeds and would let off gas peddle a little and then floor it again, it only would accelerate in the top gear. Freightliner said the factory installed the foot peddles wrong and they don't allow the peddle to go past 60%. This sounds really dumb to me that they would say the peddles/tile flooring was installed wrong and it was driven over 8000 miles and I was the first person to notice that it had no power.

It also through a FOB key error and seemed to go into limp mode and once it was cleared out it seemed to drive better for a matter of seconds and then went back to what felt like limp mode. No codes were ever found when they plugged in the scanner.

Anyone ever heard of anything that resembles anything like this?
