Right after purchasing my 2010 Honda CRV, the battery went dead after sitting for less than 2 days in my garage. Charged it up, took a fairly long trip, then let it set again. Started right up, drove it about 100 miles. After sitting for just 6 hours the battery was drained again and needed a 50-amp boost to start the engine. Dealer replaced battery 'tho found nothing wrong with the original. Drove it on and off for a couple of weeks, took another 200+ mile trip. Then after sitting for 10-14 days, the battery (the new one) was so dead, I had to enter the car manually. Has anyone had any similar problems - bad connections, failed circuits, etc that result in battery drain? The dealer can't find anything wrong.

go to another dealer. there is a drain that needs to be addressed. i am very concerned with that boost you got. that alone could have damaged a very sensitive electrical system. thank god you have the warranty, use it to your advantage by getting it extended or you may have a lemon law case. Roy

Thank you for your input. I've considered trying another dealership but the service dept. says Honda only allows certain things to be checked each time the car goes in with the same complaint. Would you recommend trying a Honda certified non-dealership shop or might that nullify my warranty? I need an expert, not someone willing to just pacify the manufacturer. Been through this horrible process once before with a 1984 VW Vanagon. What a waste of my time!! Again...thanks

Did you ever get this issue resolved. i also have a 2010 CRV EXL with the same Problem. Joe GA
COMMENT by Visitor on February 07, 2011
i am having a very similar problem. I also have an EXL 2010. My battery has died 3 ties within about a month. I have replaced the battery and each time the dealer says there is nothing wrong with the car. Any ideas anyone?

Yesterday, I took my 2010 CRV EX to the Dealer so that could check all systems to try and find what was causing my dead battery problem. Everyting checked out perfecty including my battery. I told them I wanted a "new" battery installed. They had to get the service manager's approval but I did get a new one. I'm hoping this will fix the problem but if it doesn't, I'll be again contacting Repair Pal to let them know.

I actually had my battery replaced but it happened again after that so i'm suspecting it isn't the battery. They tried to blame it on me that i'm leaving the light on or leaving something plugged in but i know that's simply not true. Anyway, keep me posted and I'll definitely do the same.

I have a Honda CRV 2010. Today morning the battery was drained out. I called the dealer and they have asked me to bring it in. Hopefully they will be able to resolve the issue. I will keep everyone posted.

I have a honda CRV 2008 and experiencing the same problem. Did you find out what the problem was. The mechanic checked mine and they said it is probably electronic issue. I will be taking it to dealer soon
COMMENT by tiredowalkin on September 27, 2012
My "new to me" 2008 CRV is doing the same thing, it sat for a week and the battery went dead, it tested 3 volts with a multi-meter, I charged it up and took it to the dealership. They said I must have left the ignition turned on!, but I always pull the key and drop it in the console. They wanted me to make an appointment to have a test ran on it, I told them they will get the vehicle back if it happens again, because they took two months to get me my title which is a state violation in itself, I have not even had a chance to plate the dang thing and told them that I might not! so they tested it while I was there,and said it tested fine now it's sitting for a week trying to duplicate the problem. I was treated by the tech rep like an idiot, yet he couldn't understand that I told them it was either a bad battery or a parasitic drain in the electrical system. Master mechanic my _ _ _!!!I don't need a lemon in my life!
COMMENT by fixitpat on September 27, 2012
Look through these to the one I posted (fixitpat). It turned out to be a problem with the air conditioner draining the battery. I was fortunate that the dealer caught it immediately. Sounds like you have a bad dealership....not sure I wouldn't just return it on that alone. Read my posting about this problem...go to them and see if this is the case. If they give you grief...give them the keys and demand a refund.
ANSWER by fixitpat on May 29, 2012
This also happened to us. Ours apparently was caused by our air conditioner....some kind of switch that would not turn off and continued to drain it. We had bought a new battery, thinking that was the problem. It was dead in a couple of days. Our dealer said this does happen occasionally. I was afraid to drive it afterwards....afraid it would happen again, but what they did fixed it.

What was replaced? I might have the same problem
COMMENT by fixitpat on August 04, 2012
My CRV was repaired on 3/15/12 and it had 48,836 miles on it when this happened. It cost me $139.96 to have it repaired by my local Honda dealer. The receipt for this says "Cust states the batter goes dead intermittantly. Diag and found A/C relay stuck and causing draining of the battery" The part cost $8.59...the rest was labor. Part # 39794-SDA (Relay ASSY). They replaced the Pressure relief valve. I have had no problems since this replacement.
COMMENT by Charmar on July 23, 2013
Thanks for posting this - it was the exact same issue I had. Issue happened today, dealership diagnosed it today and I got my car fixed today! Yeah!
ANSWER by Charmar on July 23, 2013
I have a 2010 Honda Civic, this morning the car was 100% dead, I even had to manually open the car door, had roadside give me a jump, ran for a bit okay, starting making a weird sound and died again so had it towed to Westwood Honda, long and short of it is, I have defect in a small electrical rely related to my air conditioning unit, even though the car is off behind the scenes the a/c is stuck in an “ON” mode and drained my battery. Tech said this is extremely rare to happen. Good news - car still under warranty and I should have my car back this afternoon. Perhaps this was your issue too.

Honda 2010 Civic - With 60000 miles. Same deal. Woke up to a dead battery usually after a cold evening. I purchased a new battery 3 days ago and woke up to a dead battery. Took the car to a Honda dealership and they diagnosed the faulty relay. They replaced compressor valve and ac relay (parts = $57; labor = $495).
COMMENT by amanny11 on February 10, 2015
Hi All. I've had the same issue with my 2011 CRV. After having the battery replaced 3-4 times in one year, it was finally diagnosed with a faulty AC Relay Switch. Apparently the switch was stuck "on" even when my car was off and drained the battery. The cost to fix this was about $175.

I have the exact same problem with a 2102 Honda CRV. Got a recall notice about 6 wks ago about this possible problem and took it to dealer for "reprogramming" and was told all was well. Have had dead battery several times since and it takes about 10 days for it to happen with regular use. Left it at airport for 4 days and it was deader than dead when I returned. Not impressed with Honda's apparent inability to trouble shoot though I imagine these complicated electrical systems can be very finicky. Obviously this problem has to be corrected on Honda's dime as it's directly related to a recall issue in my case.
