      2013 xc70 T6 battery drain

      Battery went out on wife a few weeks after getting car. Had her call roadside assistance and was jumped. Local tire shop tested the battery and says it's good. Noticed that the car would struggle to start and now and then won't start so it had had to be jumped a few more times. Super inconvenient. Car is scheduled for service in a couple weeks.

      Almost had it towed to dealer as we still have a bit of roadside assistance, but dealer said we were out of luck on a loaner vehicle. Any culprits on these vehicles? I can't even remember the last time I've had to jump a car and have never experienced persistent battery issues on one that tests out.

      Also, why is there no way to view the battery status?

      This and the rough downshifts have me slightly concerned.

      Car has 48k miles and warranty expires at end of month.

      2013 xc70 T6 battery drain

      Thanks for the post, could happen to anybody. Hoping for interesting answers! Helps for upcoming problems if any ofcourse. Thx for sharing. Couldnt help you on this one. Looks like something is hot wired that shouldnt be. Generator I think charges the battery? Or is it the alternator? My basic knowledge has been long gone!!- Let us know if u find any solution.

      I would say the battery is 100% the culprit. As I live in a hot country, I need to take my T6 to the garage for replacement as soon as I get the first start struggle, every 18 months or so.
      the Volvo battery tester always confirms the battery is worn out. Your symptoms match mine completely, hence I don't think this it can be anything but the battery. Please ask to see the slip from the battery tester. Please ask them to check the alternator voltage. Just yesterday I did the same procedure and I had 14.1 V charging the battery from the generator. The dealer seems incompetent or has broken equipment. In fact the dealer probably just wants to avoid changing the battery on warranty.

      It will never start again if I leave it two three days ignoring "the starting struggle" and hope the battery will be recharged if I switch off the headlights on the way home from work.

      It's possible the RDAR is causing the battery drain. There is a Software update. The RDAR controls the Sat Radio and there is a software bug that keeps it awake and will drain the battery. Only way to know if the RDAR Upgrade is available for your car is to have the dealer check for SW updates. If its had the SW update already, it's most likely a failing battery. Are you getting the Low Battery Message?

      Wife took it to les schwab, a local tire specialist who has a good reputation, to test the battery after the first time we had to get it jumped and they indicated the battery is in "great" shape. Not getting the low battery message until we try to start and it won't turn over. when it stutters but still starts, it does not show a low battery warning, but it's pretty clear it's low when it does that.

      Oh well, I will mention the RDAR/Sat Radio bug when we get it in. Bought a portable jumper in the meantime so we can jump without car to car jumper cables.

      2013 xc70 T6 battery drain

      The rough downshift; a transm oil change could do magic, well worth it. Prob never done?

      Here a quote from somebody else on Swedespeed;

      "--Thought I would post the results from my recent scheduled service visit on this issue. My service adviser did mention the RDAR software update to prevent the satellite radio tuner from staying on after the ignition is switch off as a possible cause for the battery drain. But after connecting the car to their computer they found that software update had already been installed from a previous visit. So they tested the charging system and discovered that the battery failed load test. So they replaced the battery. He figured the prior RDAR bug constantly draining the battery over time had caused the battery to wear out prematurely. Hopefully that will put this issue to rest. I also asked for and received Sensus 3.0 no problems at all LOVE the new trip stats!

      Isn't it usually the other way around, that living in a cold climate stresses the battery more? Harder to start, harder to charge, risk of freezing it, fuel heater usage and oter stuff. If you have 14.1 volts from the alternator that sounds very reasonable to me. Do you short trips exclusively?

      How many miles on the car? Around 50-60k miles it could be a good idea to have a transmission flush performed. These transmissions can occasionally be jerky, nothing I see as cause for alarm. Maybe ask the dealer to reset the adaption while you're in there, or have them perform a software update if any is available.

      As for the battery: if the battery's good but it doesn't crank well it could be a bad ground connection. Or the sirius satelite radio bug draining the battery, as someone said. If so then it should take some days for it to discharge and the car should perform as usual after the battery's been charged. Feels like the battery on a MY13 shouldn't be bad already. Try using a smart charger on it, I restored a bad battery on another car that struggled in the winter but has been performing well for almost a year since.

      Well, they

      (1) Replaced the battery. "Tested battery with VIDA, battery failed." I was biased going in thinking something was causing the battery to drain prematurely as the last place said it had a good "test." we've probably abused it in the last couple weeks jump starting it.
      (2) Confirmed abrupt downshifting and updated software. "Scanned with VIDA, codes for torque converter clutch algorithm. Performed TCM upgrade." said it was shifting much smoother.

      I suspected the battery. Sometimes a battery can fool a battery tester. It can have a "surface charge" but not a deep charge where the amps come from to start an engine. I would really doubt any modern radio would run down a battery unless the vehicle was not started in several weeks. Batteries fail prematurely for a variety of reasons. Because of all the electronic devices on the xc70 the battery is under more stress than many other vehicles. And by the way, it would be a good idea to change the ATF.

      Thanks gorj. The ATF flush/change is high on my list.

      We're on our fourth battery since buying new in 2010. OE lasted ~3 years then I've replaced with auto store mid or upper level batteries every 18-24 months. Heat in Houston combined with the ridiculous amount of heat under the hood cooks them. I don't know why Volvo moved the battery to under the hood from the previous generation - 5 years with the original battery in our '02 and it was still going strong when we sold it.

      I also have to top up the coolant overflow container 1-2 times a year from evaporation. It's hot in there.

      I understand at times it feels like a knifefight in a telephone box and you are armed with a toothpick. Just changed one on my wifes V40.

      So I have been struggling and ignoring and struggling to ignore this problem. Our 2013 XC70 with 50k+ miles needed the brake booster vac pump seal replacement last winter. I removed the battery etc... and did the work, put it back together and the Mrs started reporting low battery warnings every day after driving 26 miles to work. It only took a minute or so for her to gather up her stuff to leave the car. Took the battery to Walmart it's only 18 months old at that point and they tested it as good and I saw the printout. Went home and performed various VIDA tests and it checked out... no failures. The car starts and runs fine, but I don't trust it. Since then i have just ignored it until I can come up with some other test or theory.

      Did you go into the CEM and reset the Counters after Battery Replacement?
      Vehicle Communication/CEM/Advanced, scroll down and its in the second group from the bottom. I think it says Resetting Battery Counter after Battery replacement.
      I would try that but its also possible that the battery is below or around 80% health and the CEM may throw battery message even with a sufficient battery to start car.

      Thanks for the suggestion. That sounds familiar and I believe I reset the counter. Maybe this weekend I'll connect up and see if that looks like somewhere I've been.
