Friends, back again seeking suggestions...
Yesterday morning I had to drive to a local Staples store about 7 miles away... Morning seems normal... No problem starting the car or driving... I was inside Staples for about 30-45 minutes... Came out of the store, put the key to the ignition and problem starts... Car wouldn't start!!!
Tried jump-starting the car with the help of a fellow gentleman... The car still wouldn't start... I could only hear a clicking sound... On the dashboard I could see some signs that would flicker and go away... Only noticeable thing is the sign of a clock with 00:00:00 written below it.
I never have seen that sign before and do not recall receiving any warning message that will tell me about any battery issue.
I had to call AAA... The guy came and also started with jump starting... Only difference is this time we were trying to jump start from behind connecting the cable directly to the battery terminals (first time we tried using the terminals under the hood)... Nothing worked until we tried charging the battery for almost 1 and half hour... The car finally started.
I drove back home and then left the car running for about another 20 minutes... I thought the problem was solved for the time being... I understood the battery would need replacement... In the afternoon I thought I should check it out and I found I'm back to square... This time I jump started the car myself using my other car and it took me about 30 minutes... Again, after starting I left it running for about 40 minutes... However, after I turned the engine off I couldn't turn it back on!!!
Any idea what could be the issue here... I doubt it is just the battery... All lights, AC everything turns on!!!
BTW, if you remember I reported my incident about low octane gas about a week back... I attached the link of that thread for your reference below... Is there any chance these two things are related???
