2021 Nissan Versa Engine

Driving down the road, the car enters a phase where you can not accelerate at all. It seems like the fuel injectors are cut off by 90% and you can only accelerate to about 35 mph. Although this has happened the whole life of the car 26,000 miles, today I was fed up with it and decided to make it known there is an issue. I've tried different fuel and that did not fix it. As a mechanic myself, I feel there is some kind of programming fault from the factory. I have taken my car into the Nissan dealer and they told me they couldn't find anything wrong and maybe i was using the wrong fuel. I told them the correct fuel was being used. Their technician told me i bought the wrong car for the harsh Minnesota environment. That did not please me. Thank you for your time and hopefully you can have a serious talk Nissan about this issue.

Car is still pretty new (less than 6,000 miles) and it is experiencing a loss of coolant. It was near the "max" mark on the reservoir when purchased brand new and now it is riding on the "min" mark. I have been checking my fluids and such occasionally since the day I bought it and have watched it progressively go lower. In comparison, I have a 20-year-old pickup truck that I personally replaced a head gasket on over a year ago and it holds coolant better than this brand new Versa. Wouldn't be surprised if other new Versa owners are experiencing the same issue. I'm doubtful the dealership will do anything quick to fix it
