2 months ago I got my battery replaced when it started dying very often. Now the same thing persists, if I don't use the car for two days the battery dies again. I took it to the dealer and got it tested and the dealer gave me a report saying the battery is good. I have to jump start it every time.
2011 Hyundai Sonata GLS A/T
I've had this issue for a while now but is seems to be getting worse the older the truck gets. I've had the battery, and alternator tested multiple times and they always receive passing grades. If the truck sits for a period of several days or more without being started, the battery is sometimes dead when I go to start it up and go somewhere. It is really frustrating because it seems to happen and very random times, when I least expect it.
Sometimes I can go start my truck without any problems at all after a week or so. Sometimes it won't start if I leave it alone for only a day or two. Usually after I jump start the truck it will run fine and start for the next several weeks. Is it possible that there is a short somewhere causing the battery to drain sometimes? Also, there is sometimes a buzzing sound that comes from under the hood when it is warm outside with the engine off and the truck at rest... could they be related?
I have a 2005 Hyundai Tuscon. If we go out of town, or any time we don't drive the Tuscan for three days or more we always come back to a dead battery. I mean really dead. I mean, get a new battery dead. Since 2005 when we bought the vehicle new, we've had nine—9—new batteries put in. The last one was a heavy duty battery recommended by the dealer.
This problem started after the dealer replaced the OEM radio. We've had multiple checks done on the engine to find out where the (battery) draw is coming from. I researched and found a Hyundai Technical Service Bulletin saying that the problem is from a defective stereo. But my dealer says they can't locate the problem.
We've also had the battery posts cleaned and other things done. The vehicle runs fine and has had few problems except for this nagging battery problem.
My Mom purchased a new 2011 Lexus RX350 last spring. The dealer installed a remote starter at the time of purchase (we live in Alaska). We've had a continuing problem with the battery going dead if the car has not been driven for a period of time (like 4 days). When she does drive it, it is for short trips (3 miles round trip to work). The original battery was replaced in fall with a heavy duty one, but the problem continues. Its been to the Lexus dealer (130 miles away) several times, but they claim everything is within the tolerances and "there is no problem".
They did note that the remote starter was drawing more than it was suppose to and reinstalled it. Their finding was that she was not driving it enough and recommended a battery tender, which has been installed. That works as long as she plugs it in daily. However, if a plug in is not available (like at the airport, hospital or if she is visiting) the battery goes dead after 4 days (even after it has been driven 100 miles).
In my 2014 F250/6.2, if the truck sits unstarted for 10 - 14 days it will usually kill the battery. I mean dead enough to not even power the dome lights. Do the various modules in these trucks draw that much that it would cause this? I'm getting ready to install a couple of 5 Star tunes in the truck. But if I need to take it to a dealer for some warranty coverage for this problem I'll hold off. There's never been a tune in it to this point and I don't want a warranty claim denied for that reason.

View 3 RepliesI had to take my car for Oil Change and I had the driver door lock replaced. I think it is a common problem with the Sonatas to have the driver door power lock issue.
The mechanic was doing it by the book so he decided to disconnect the battery before proceeding. His work is really neat, the door is working again.
After leaving the shop, I noticed the Check engine Light coming on! I have one of these BT modules, so I checked the code and it says: P0106. The car is idling fine, driving fine and there is no noticeable issues what so ever.
I stopped on the side, turned off the engine and with ignition on, I did reset the MIL. But the MIL came back in the second driving cycle. (turn off and then on).
Do you think I need a new MAP sensor? I've seen some Optima's owners with similar problem but I can't find how the problem has ended with them.
Today, I drove to work, 45 Miles with the coded pending. Once arrived to work, I turned off and then on the car and the MIL is on again.
My battery is dead, but I need to drive for 5 hours. Can I boost it and drive for 5 hours on the highway? Would this damage my car? I can replace the battery when I get home.
View 4 RepliesCharged battery, tried adding my 100amp charger "jump" mode on when starting, took off ground and ground down to metal where it attaches, cleaned all the contacts, tried a known good battery. Yet the car still clicked when trying to start it. I removed the starter and wired it with appropriate gauged wire, and had someone turn the key while I held the starter and it operated as it should, no clicking. What should I try next before I re-install the starter, so I don't end up having the system clicking like there is a dead battery again? Because I certainly didn't fix anything.
View 5 RepliesJust put a new battery in our 2011 Sonata, now the radio doesn't turn on. Didn't find anything in the owners manual about this, and when I called the service dept at my dealer they said "I don't know, you'll have to bring it in". Hope it might be something simple to reset?
View 7 RepliesI have a 2013 Hyundai Sonata GLS with 55,000 miles. I was told to replace the plugs and battery by my local automotive shop. I decided to do it myself to save a couple of dollars just this past week. I filled up the car today and noticed the MPG dropped significantly. Normally a full the tank shows I have 420 miles to go. Today it showed 370 a difference of 50 miles.
I have two ideas why this happened:
1) Replacing the battery has caused the computer to reset and as a result it is showing the wrong mileage. After a week or two of running the correct mileage will show. I drove the car about 150 miles after changing the battery and thought this would of been enough time for the computer to figure out the MPG if this was the problem.
2) I caused damage to the Iridium plugs when I gapped them and did not notice it. I used Autolite XP6203 model and gapped them at .044. Autolites do not come pre-gapped I was told. The car is not hesitating and runs smooth. I am thinking this is the problem but not 100% certain.
Is my idea about the computer valid and I should give it some time to recalculate MPG? I am thinking to give it a couple of tanks of gas and see if the car fixes itself
I'm fairly new to these cars. I just bought one used 2 weeks ago. lately in the very cold new england mornings i am seeing the battery light flash at me when downshifting on the highway. seems to go away after about 5 miles and doesn't happen every day. Belt and the tension look ok. My car is stock and has 52k on it.
View 10 RepliesGot a new battery today but now the check engine light is on. Went to local auto parts store and was told it's the MAP sensor. I had the battery replaced 3 years prior to this and at that time the check engine light didn't turn on. Is that normal?
View 4 RepliesGot a 2011 Sonata back in 2010, drove for 4.5 years and battery is finally showing weakness this winter, planning to replace the battery, but unable to find the recommended battery specs from the owner's manual.
View 5 RepliesI just brought home a shinny new 2012 Hyundai Sonata Limited with Nav and it's awesome! Just discovered something though...
When the engin is off and I am running the radio I get the Battery Discharge Warning pop up on the Nav screen accompanied by a beep. It goes off every minute or so.
This is going to be annoying next time I go to the drive in that we like to frequent as we need to play the audio on the FM radio with the car turned off.
How I can turn this off or disable the sounds at least?
I had a sensor error which caused my battery to drain. The computer thinks my door is unlocked when it is locked, leaving the door open image on the dashboard. This caused my battery to drain totally. What the damage would be for a new battery and fixing the door sensor ?
View 11 RepliesI was installing xenon supply HIDs in my 2012 Sonata and when attaching the power cable to the battery my ratchet went ahead and touched metal while it was assisting me in tightening the nut
Small spark, tiny puff of smoke and the popping sound associated with such an event. I see what appears to be a little fuse under a clear plastic cover on the positive battery terminal itself. On it says 150 AMP. the pop sound came from that. So I am assuming its blown.
Here is my real concern...the red battery symbol now stays on when I start the car...
I have been out of the country for the past 3 months and I left my car at my parents place. I have a 2011 Sonata SE with Nav. I got a call from my dad saying that my car is dead (battery) and the doors have locked. He previously was able to jump the car since he was able to open the doors with the key fob remote. Now the doors will not open. I assume the battery has died beyond where the key fob can open them. I return back home this week and would like to be able to deal with this headache before I return and come back to a working car. How to get into the car or at least popping the hood without being able to get in the car? I've read up about other cars having a backup battery or special mechanism on the door handle for these situations so I would think Hyundai thought this through...
View 35 RepliesI replaced the battery in my 2011 Sonata. After the install I reset the radio, clock etc. and everything seemed to work fine electronically. The car was very low on gas and when I filled it later that same day the "Distance to Empty" display in the dash only read 271 miles after fill up. Typically when it is filled it reads 550+ to empty. After three tank fulls the display now reads 375 when filled up. Is there a reboot for this function? Does it have to be done by a dealer?
View 21 RepliesI just bought a 2012 Prius c. There are oftentimes when I don't drive my car for a few days. When this happens, I have heard that the car might not start, especially in the winter. Is this true?
View 7 RepliesPrius was running wonderfully until a few weeks ago. Recently, about 2 months ago, bought a new 12v battery. Everything was working fine.
About two weeks ago, the car wouldn't start. Jump started all good. Drove fine. If left unstarted for a day, it goes flat the next day. If driven every day, car will start fine.
Battery volt reads 14.1V whilst driving. I checked on the MFD screen.
