Battery dying constantly

Recently purchased a 2010 QP with 17K miles and the car is perfect, except for the fact that there is a phantom parasitic load that drains the battery after 24-48 hours. Been to the dealer twice, and the computer says alternator is fine, no drain on the system detected beyond factory spec. Have changed the battery with a new one three times, and it still happens. Have checked the usual suspects: parked locked versus unlocked, light in the trunk, etc., still no remedy Have seen other threads where this has occured - any ideas? Security system? I love the car but this is maddening and the dealer just can't identify anything wrong. All suggestions appreciated.

That's a pretty hefty drain to do that. You need to get a multi meter and start checking individual circuits starting with the main power cable to the battery. The draw should be a few milliamps, 70-100 or so? Just taking an educated guess there, no clue what factory spec is. Then it's checking one circuit at a time until you find the one out of line. Good luck!

Well I don`t think it is gonna be the battery after replacing 3 of them and I`m not sure your gonna find the answer here...Battery drains can be difficult to locate on a modern car as the computers are on a network...Just like a laptop times out and goes to sleep the cars computers do the same thing after about 45-60 minutes...Sometimes you can have a computer that wakes back up and awakens the whole network causing a drain...I`m surprised they have not be able to find it...The larger the drain the easier it is to find and your would be pretty large if it drains the battery in 24-48 hours.....The meter they are using should have a record function to verify it is a drain by the way.. You can also have drains caused by hidden Lojack devices and GPS locators..I would take it back to the dealer and let them keep it for several days and test it some more as it may be randomly draining or find another place to look at it...I agree it`s kinda unacceptable....good luck...Jason

I had a similar issue on an Escalade. Took over a year to find it. The rear HVAC module was operating on a similar frequency as a neighbors garage door opener. It would shut down after 5-10 minutes, but if they activated their remote for their garage door, it would 'wake up' the module and it would stay on for another 5-10 minutes. Depending on how often they used their remote vs. how often the Cadi was started, I could get a dead battery in 2-3 days. Replacing the module fixed the problem, but it was an absolute b*tch to find... since no dealer or shop had the remote trigger I had at home, they couldn't find it.


Sorry for the uplifting post, but with all the modules these cars have in them, be aware it may be quite a while to locate the culprit. I think I'd get a battery tender and keep it on that full time.

It's mind boggling to me that any car manufacturer would use the same waveform for their control units as those used by garage door openers. Somebody wasn't thinking straight in Detroit. Thanks for the post. Truly amazing.

I can't confirm that story and I'm not saying you are making it up but that's the most unbelievable excuse I've ever heard. Unless the car has a wireless remote for the climate control, there is no way a wireless anything could affect a wired system within another vehicle. Besides that, how often could the neighbors possibly have used the garage opener to make that an issue?

Again, I'm not calling you a liar but I think they were pulling your leg on that one a bit once they discovered the faulty module. I'm an electrician by trade so I know a few things about how systems work and this one doesn't add up.

While that does sound odd about the GM vehicle...I have seen a few cars do exactly what he described.. Range Rovers around 95 and up had an issue with the RF receiver and would pick up stray signals and wake the system up and drain the battery.. However, I don`t think that is gonna be the case here...Jason

Believe it or not. Doesn't matter to me. I got no reason to make shit up or 'lie' about something. I'm the one who finally found the problem, so it wasn't a dealer 'pulling my leg'.


And Jason, I wasn't even slightly suggesting this was his problem, I was just using an experience I had to demonstrate how difficult some of these problems can be to narrow down with the complexities of modern automobiles and the way that dissimilar items are integrated.

I didn't say you lied, that was exactly what I was trying to avoid but it's difficult to accurately convey a thought with the proper tone via written word. Apologies if you felt I was being accusatory, that was not the intention I assure you.

In other news, any updates from the OP?

Check with multimeter on battery if the quiescent current is less than 0.05A.

enjoy
