Hi everyone,
I had an issue on August 23, 2020, where the car slowed down and over-revved twice. Today, I took the car to the dealer this morning, and was told (1) Honda's Diagnostic tools could not find indications that an error or an issue occurred, (2) could not replicate the problem, and (3) without a diagnostic capture of the incident the dealership could do nothing about it.
After some research today, it seemed like others may be having similar issues. How were you able to (1) resolve the issue with Honda and (2) able to help document the Computer error code so the next time it happened?
Would anyone recommend an OBD tool that can monitor in real-time what "gear" the CVT is in, engine loading, speed, temp, and other parameters that may help isolate the problem while driving?
Here is what happened below:
(1) State of the car:
Car was in HV mode with 75% of battery, and not going uphill.
(2) Symptoms:
While driving or starting from a stop, the engine sounded like it shifted into a lower gear by the loud engine revving noises it made. It occurred twice.
(2a) Occurrence 1:
While driving at 35 miles an hour, the transmission sounded like it went to a lower gear, and the car was slowing down even after pressing on the gas. What seemed to address the problem was turning off HV mode, let it go into EV mode, then put it back into HV Mode.
(2b) Occurrence 2:
Between 10 to 20 minutes later. From a full stop at a stoplight, the transmission sounded like it was stuck in a lower gear, pressing the gas did not accelerate the car past 19 miles/hour. What seemed to address the problem was turning off HV mode, let it go into EV mode, then put it back into HV Mode.
In both cases, putting the car back into EV Mode, then back in HV mode, seemed to resolve the problem of the loss of power and engine over-rev. It seems odd to me that Honda would not have a fix for this yet.
