Today my 2017 journey sxt with 89,000k miles went into limp mode with a red lightning bolt symbol on the dash. I have codes U0401-00 and C121C-00. I was able to drive the car home but there is just about no throttle response. All considered, it ran smooth. I can't seem to find anything on these codes that make sense to me. Was wondering it anyone has came across this in the past that can share some insight.
