Is My Honda Clarity Fixed?
Thought I’d write a quick update as a full post, rather than update yesterday’s post here.
Since the battery was dead in my Clarity so I couldn’t start the car, I called Honda Roadside Assistance. The tow truck driver did jump the car and it started, but there was something obviously wrong so I had the car towed to my dealer, Rancho Santa Margarita Honda, on Tuesday in the early afternoon.
Finally, after TWO DAYS of repeated calling and talking to several of the service advisors to find out what was going on with my car (there were seemingly multiple advisors on my car and no one returned my phone calls promptly or had answers) I picked up the car late yesterday after calling-in to talk to the general manager of the store to get some action.
The punchline? Is the car fixed? I have no idea but suspect it is not. Why? Because there is NO explanation as to why the battery was completely dead. Or why the check-engine light was on four times in July and August with the same error codes. Forget about any explanation on all the other issues I’ve had like this dangerous one after only a few days with the car.
The fix? Basically the service tech “reset” the car by clearing the codes, reset the steering and braking sensor system, but apparently did not identify any root problems with the control systems in the car. There were no software updates required (or performed) and apparently no aberrations or issues uncovered, even though there were several error codes and all of them show that there is some issue with the car’s internal communications system (likely bugs in the software and/or problems in the communication bus within the car itself):
- P1D00 – All CAN Malfunction Battery Condition Monitor Module – CAN is the bus and it talks over the powertrain control module (PCM). My guess all along is that there was some kind of fundamental bug in the software control system which is spawning errors.
- U0100 – Lost Communication with ECM/PCM “A” – More of those “lost” communication problems.
- U1204 – Invalid or Missing Data for Steering Column – The Transmission Range Sensor (also referred to as the PRNDL input an/or neutral safety switch) tells the transmission control module (TCM) an the engine control module (PCM) that the transmission is in park, reverse, neutral, drive, low, 2nd, 3rd etc.
- U1600 Reverse Input Circuit – The reason for a U1600 error is to cause the service tech to check system wiring, connectors, or other electrical components which are subject to failure. Another reason why I think there is a computer system malfunction within the car itself.
In my printed receipt, here is what they gave me showing what they found and the action they took to “fix” my problems:
After reading this Inside EV forum thread about others with goofy Clarity electronic issues, my level of confidence in the Clarity is at an all-time low, after only three months with the car and 4,600 miles.
I’m going to give it two weeks and, if there are continued problems, I’ll ask Honda to buy back the car or I’ll sell it on the secondary market (or likely trade it in on a Tesla Model 3).
To be continued…
