Before I waste anyone time I would like to point out that I do have OEM battery installed in the car which is almost dead. I will be changing it today. But with battery charged the hazard light comes on automatically for some reason and drains the battery. I am hoping its just one of the symptoms of bad battery as the tail is being naughty too.

To fix the hazard flashing is to just relock the car from fob and it stops.

 

yep, most likely battery, and I do so hate it when a tail is being naughty ........

 

Alright so changed the battery and the lights came on once again after driving it for 30min and parking it + locking the car. Went to grab a bite and saw the light flashing. Came out and saw that light were flashing and the alarm was basically sounding in muffled voice. Like the voice was trying to come out but it couldn't cause of low power to it ? Does the alarm have its own battery? anyways I locked the car with the fob and it went away. But I am just scared that it might drain my new battery so I keep on checking my car after few hours at work lol

 

Yes, the alarm does have it's own battery, but most are toast by now.
As to battery drain, you can remove the neg (-) battery cable and connect a multimeter between it and the neg battery post. You should see around 35 ma normal drain.
If you see a heap more, start plucking fuses till you locate the source circuit.

 

I always wanted to use multimeter thanks for the heads up I will check it up over the weekend. I am also doing search on the forum and I think I nailed the issue.

I am posting my find for someone else who might have this problem in future.
