Came here as my 2010 RDX with 130k kms (80k miles est) didn't want to start.

I suspect it's the newly installed dashcam (installed 1 month ago) AND car sitting for >1 wk unusued.

As I charge the battery up right now (and am at home sitting on my computer waiting for time to pass), just wanted to see if I am "attacking" the problem correctly based on the symptoms:

a) literally when I turn the key, not even a sound, a click, nothing - only the brake light engaged sign lights up and then dashboard light (and the light dies slowly after).
b) VIOFO dashcam: I don't remove it from the lighter socket (I presume this is the culprit? - the manual did say it will not draw power - but I don't know if our RDX lighter socket does draw power even if engine is off)
c) I read other posts here indicating it could also be the bluetooth - but that is what I'll "attack" AFTER I make sure it IS the lighter socket drawing power from the battery

Please let me know if you think it's any other problem: eg starter, alternator etc... The engine does not even crank FWIW. Literally nothing save for some lights turning on.

Many thanks for your thoughts.

 

I doubt it is the dashcam, but if you are worried there are harnesses available that plug in-line with the rear view mirror wiring (assuming you have auto-dimming mirror). It's a cleaner install and there is no power supplied when the car is not on, so no way for the camera to drain the battery.

 

Invest in a multimeter and check the battery between starts for like a week. Should help you isolate the issue. Ie disconnect the dashcam and check if the voltage drops, etc.

 

After 6 months or so, it's a dashcam or lighter socket fluke and/or the battery -- I replaced the battery and it seemed like Kirkland battery has "deteriorated" in quality (or kirkland battery i got was a fluke)-- meaning: if the dashcam was indeed draining power, either the battery sucked (eg Kirkland) or this new battery from the CAA is better... how do i know this? well, i forgot to unplug the dashcam again for a week and this time, car started easily... FYI kirkland battery was only 1 yr old when it didnt want to start in the middle of summer last year...

PS I won't muck around with the bluetooth system for now, even if i don't actually use it at all...
