battery

Since late July, my vehicle has experienced a recurring parasitic battery drain and multiple electrical system warnings. Timeline Overview: 07/31: “Stop the engine and check the brake system” warning appeared; dealer found no issues. 08/02–08/04: Battery completely dead; car towed and...

I was recently impacted by the Connected Services problem (Feb 2025) and had to disconnect/reconnect the negative battery cable in the trunk to hard-reset the Infotainment system (fixed). After receiving a prior battery low warning while in Accessory mode, I decided to charge up my battery...

Hi, I've been looking at Genesis for some time now. I finally went with the G80 over a G70 and am having a good time with it. The battery will need replacing soon so i came to see if there was any information i should know above the generic battery replacement methods? Thanks for having me.

Can it be true? I received an email from Genesis earlier today telling me I can precondition the battery via the app or in vehicle: 1. Inside your vehicle or using the Genesis Intelligent Assistant app, go to EV Settings and select “Winter/Battery Conditioning Mode” to heat up the battery in...

After experiencing this issue about a month ago, and receiving the new VCMS software update (campaign 910G) as a "fix", the "Check Electric Vehicle system" warning is back. Charging is once again limited to 80%, right before a roadtrip (just like last time). As before (Diagnostic code P1AA900...

My new GV60 standard (~2600 miles on the odometer) recently threw code P1AA900 with a "possible condition with your Battery Management System has been detected" warning. Have scheduled a service appointment, though not nearly soon enough: limited appointment availability at my dealer. A few...

TLDR - what are the ways to conserve battery in the GV60? I watched a video and understand AC at 72 etc but is in car navigation more conservative than carplay? How bad is bluetooth? I’m guessing adaptive cruise control uses a lot of power, but what speed should I go to use the least amount of...

I have a 2013 Hyundai genesis 5.0 r-spec. So my car was sitting for a couple weeks before I tried starting it and I tried starting it with a jump starter that didn’t have enough cold cranking amps so it just did it’s normal thing we’re it ticks under the hood multiple times. So it tried to jump...

Hi! I’m wondering if anybody else has had similar issues with their Genesis Gv80. I purchased this car BRAND NEW from our local dealership in May 2022. When I got the car, one of the keys wasn’t working correctly, but I didn’t think much of it. I spent the summer driving my car and eventually...

Hi everyone, hoping someone here has had this issue. A month ago I noticed a low battery on my 2012 Genesis Rspec 5.0. I thought i had left the trunk open and maybe the light drained it a bit. Then a week later it was dead so I had it replaced. Battery light never came on. Then this past week...

Over Thanksgiving, I took my first road trip (227 miles each way- NJ to DC suburbs) and have a number of notes and questions to throw into this forum. Charged to 100% the night before (Level 2 home charger). Range showed 247 miles. The outside temperature would be 40-55 degrees for the trip, so...

I already posted this on the General Genesis forum. I replaced the battery on my 2017 G90. Because Interstate wanted to try to charge the old battery, the car sat for 3 or 4 days with no battery. After I installed the new battery everything worked fine EXCEPT that I intermittently get a warning...

I just replaced the battery in my 2017 G90. Because I had to wait for Interstate to try to charge the old battery, the car sat in my garage for 3 or 4 days with no battery at all. I installed the new battery and everything works fine EXCEPT I get intermittent warning lights and bells to “Check...

I went to start my car yesterday morning and discovered multiple electronic issues. - The proximity mirrors did not fold out - The doors did not unlock using the button on the door handle - Neither key was recognized by the car - The car won't start - The driver window went down but wouldn't go...

Was wondering to hear anyone's experience on getting replacement batteries from the dealer. Bought a Hyundai flooded H8 battery from the dealer today for my 2012 4.6 and was told that the OE battery is flooded and the replacements are also flooded. Was expecting these to be AGM, and poking...

Hello, I've searched the forums and did not find the answer. Maybe my experience will help someone else. I was having an intermittent loss of all electrical power-no entry, nothing. I replaced the battery last year and so I checked the connections (I'm a old electronics tech) and removed the...

CAR: 2015 Genesis Sedan 3.8 Technology AWD Canada Do I really need to remove the battery before I can charge it? This seems crazy. The manual is not very clear. I want to charge the battery from the + and - connector under the front hood. But the manual says: NEVER attempt to...

As most of us know the warm climates are harder on automotive batteries than cold weather. Down here in florida the best warranty I can find on standard technology auto batteries to fit my 2013 Genesis sedan 3.8L (size category 49/H8) is 30 months free replacement on Interstate's best...

Just as an FYI, yesterday when my original, 4 year old battery finally died, while I was searching for a trustworthy replacement, I discovered that the OEM Hyundai battery that the dealer sells is an H8/grp49 Interstate battery. The dealers I called wanted about $215 for the battery. I instead...

Do I have to disconnect the battery to pull the driver seat out of the car since there is apparently an airbag built in? If so, will I lose all my settings, etc.?
