I refered him to ask here from the FnF main forums, from what I understand his problem is:

- When his headlamps are switched on, the tail lamps with the LEDs also switched on and works normally.

- Problem is when he press the brakes, those LEDs on the left tail lamp won't become brighter to indicate braking. The right tail lamp and third brake light works normally.

- If the headlamps/tail lamps are not switched on eg. daytime driving, the left tail lamp LEDs won't lit up at all during braking.

Mine FLX Se with 136k mileage able to achieve 11-15km/L.. depends on driving style. Mostly city driving with start stop condition, if found highway and straight road will performing F1 style.  I'm in marketing line FYI. Not sure the reading ok o not.

Try calculating using km/l instead of rm/km due to possible inaccurate figures caused by the constant RM value fluctuation. Mine average 13-14km/l highway and could be as low as 10-12km/l in mixed city, highway.

I see Bro. Let me do it next trip then update again!

The USB Cable can be another factor. 

Never used car charger. Sorry..

I used a 2.4a car charger previously to charge my note 4. It charged quite ok to me but i didn't use any apps during its charge. I used the cable that comes with my phone to charge it. Now ive upgrade to aukey quickcharge 2 charger

with the aukey charger it charges my note 4 slightly quicker than the normal 2.4a. yes waze (or any apps running) does draw power due to the screen stays on. for other cars, not sure because seems like im the only one that uses a car charger
