You should CONTINUE give them feedbak & updated them that they have yet to resolve the overcrank issued, asked them to adv what to do next to have this resolved. Last time I also compliant to them right after my 6K service & went back to check but can't find any abnormality then claimed my Brake safety lock causes all this nonsense... Till I raise my voice only then the foremen asked to log into "MRR" to get adv for next course of action.

Since your EB need more them 3 times to overcrank frequently, why don't you video/sound record it & show to them during the complaint?? This will definitely help to speed up the troubleshooting I think..

Where and how to check battery voltage?

can u share where you buy it? what brand and model ? TQ   

Guys,

For me i always practice to crank AFTER the warning signals go off - abs & airbag warnings! Been doing tis with my old cars - Wira, Spectra, Optima. So far soo good. Only start up @ the 1st crank. Only twice got issues with my EB but in that case the 'gearbox' warning sign came off. After reflushing the ECU its now ok.

Just my 2 cents...

I just checked my battery voltage just now when I got home. I got home and shut off the car at 5.30pm.

At 6pm, I plugged in my OBD adapter to monitor the voltage.

Before start up, voltage was 12.3V.
During start up, voltage dropped to 11.0V.
When engine is running, voltage was at 14.0V.

Is this normal?

I have yet to try out the voltage during cold start. Will report back when I have done so.

You may DIY a voltage stabilizer for your car
