My 2013 SV has been at the dealer for two weeks now because they can't find the reason for my power meter gauge false reading problem.
Long story short: they replaced the traction motor on it (motor only, not inverter nor charger) because of a small noise during acceleration/deceleration. It did solve the noise issue but when I took the car back, I noticed that my power gauge meter was no longer accurate. Running 70mph on highway would give me 5 kw reading or so. I even ended up a 40 miles trip having a 14 miles/kWh average (!). Took it back to dealer, no relevant DTC.
So obviously something went wrong during the motor swap operation. I've been reading the service manual in an effort to find a clue on this behavior and found that a DTC can be thrown in this situation but only if "The difference between the estimated power consumption calculated based on a torque value from VCM to the traction motor inverter and the actual power consumption calculated based on a high voltage battery voltage and current is 54 kW or more."
Which is ridiculous in my point of view, I mean a difference of 54 kW is really huge.
I was suprised to see that the motor power consumption is calculated and not measured, the manual says: "POWER CONSUM (MOTOR) kW Displays the traction motor estimated power consumption calculated by VCM from the traction motor torque and vehicle speed."
So since my speedometer reading seems to be ok, I assume that the reading of my traction motor torque might be wrong.
Anyone here have a clue of where to look to solve this ? I want my Leaf back, 2 weeks driving an ICE car is really painful
