2010 Honda CR-V Q&A
2010 Honda CR-V Question: Battery drain
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. - jocar124
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.

Did you ever get this issue resolved. i also have a 2010 CRV EXL with the same Problem. Joe GA - Visitor
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. - fixitpat
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. - Charmar
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. - Don 1938
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). - Rebsatx
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. - MiketheTike

I think it my be the A/C relay switch, because they are known for getting stuck in the on position. My A/C light has always come on (in winter) when I'm not using it. It sound like it may be rela...

Nothing added to vehicle that takes power.. Could ignition switch be the problem or what else could it be ?
