Yes. If you live in GA 4 years is already pushing it. In hot/humid climates like the southeast, 36-48 months is completely normal for battery life (for any battery, not just Lexus branded batteries). I'm in Tampa and my 9/9/14 in service vehicle had the battery fail the load test 1/11/18 and was replaced by Lexus under factory warranty. My vehicle spent its life between Tampa and Atlanta.
You should get your battery load tested annually after the 2nd year of ownership. A battery load test is free basically everywhere, including at the dealership.
I'm still driving with the original battery in my 2013 450h, car was built end of 2012, so about 6 years now.
Then again the hybrid system uses the 12v battery a lot less than the non-hybrid. I'll probably load test it soon.
Also I only use the car 2-3 days a week, since I work from home.

That sucks to have to replace a battery every 3yrs. There was a batch of 2013 GS that had a parasitic battery drain from the network gateway ECU. Lexus issued a TSB for it.

ya my car is out of warranty for that tsb. so I just have to replace the battery every 3yrs. =(
In the future you should have your battery load tested once a year after the battery becomes two years old. A dead or jumped battery can cause a lot of glitches in some of the electronics(e.g. A/C, automatic parking brake, etc.), which is expensive to have diagnosed and resolved. An annual load test of your battery can be done at no-charge by a NTB (National Tire & Battery) store employee in their parking lot in about 5 minutes.
On a daily driver with real use, 3-4 years is about typical.
If it stays garaged a lot and you drive like grandma you might be able to get up to 6 years out of it.
Also, any time you kill a battery (eg, say you left a light on or something, etc) and drained it out, and needed a jump... its like a cat losing one of 9 lives... thats how much that punishes the battery. Batteries that have been "slammed" several times never seem to last as long as ones that have never had that happen.
Went out of town over the weekend and GS wouldn't start upon return yesterday. "CLICKCLICKCLICKCLICKCLICK!"
Jumped her off and all was good remainder of day. Just to be safe, put a battery charger on overnight.
Fast forward to this morning... "CLICKCLICKCLICKCLICKCLICK!"
Nalley Lexus is Roswell got me in at 10:15 and I was out the door with a new battery at 11:30! Great service.
Car was first sold in December 2014. Build date was 10/14. Is ~4 years 'normal' for a Lexus battery?
under 4 years is normal for cars in the south. Northern cars batteries last longer because summer and heat is what really kills batteries. Lexus batteries are made by panasonic anyways. Here in Houston around the 3 year mark you really start to be suspicious about how much longer the battery will last. Whats even better is to preemptively replace it in the 3-4 year mark because it will die suddenly in the worst time and place.
should just take the battery to an autozone where they can load test it and confirm if its dead or not, get you a replacement on the spot. It wouldnt take anywhere near over an hour. Walmart batteries actually have a good warranty 3 year replacement + 2 year pro rated
What gets me is why some people with a 4+ year old battery think their battery will always give them some kind of forewarning before it fails them, which is seldom the case. They refuse to have their aging battery load tested, which oftentimes can save themselves the headache of being stranded. But the people that really blows me away are the ones that have an aging battery that has already failed them (in that they needed a jump-start), but they try to 'repair' their old battery by charging it - thinking it should last a lot longer. I guess some people think that because their old battery starts their car today that it should last forever. Considering a new battery will usually last 4+ years it is not a very expensive wear item.

The ONLY way someone who has had to jump their battery should continue to expect pre-jump performance from the battery is if they did something that caused the battery to discharge directly. Such as leaving lights or other things on that were allowed to drain the battery directly. Beyond that, the only reason for the battery to discharge itself fully if it has not just been sitting idle for 6+ weeks is that it is nearing end of life.
Batter Longevity - Normal?
