I just got back from a 3 hour trip, parked my RX350, went to use it a half hour later and the battery was stone dead. Had to jump it. This has happened 2 times now. Has anyone had this problem?

Another quote like yours:

I have a 2009 RX350 with 43,000 miles. (still under warranty) I've had to jump the car off four times in the past 3 weeks and have taken it to the dealer twice. Both times they said the battery checks out and can't find anything wrong. They suggested that maybe we left the key on ACC and that drained it. That's not the case. The battery is shot, I replaced it today and they agreed that the battery was bad. My question is that: 1) could something else be draining it? The dealer said that they couldn't find a parasitic drain or 2) Is Lexus service incompetent and dishonest? This is our first Lexus and so far, I'm totally unimpressed. Thanks.

My reply to his statement: I have a 2010 Lexus R350 with identical mileage and identical issues. I had it checked and asked to have it charged at a local garage. They reported that the battery was bad and wouldn't charge fully. I immediately drove the 60 miles down curvy mt. roads to nearest Lexus dealer. This is the second battery to go bad. The first was the one that came pre-installed with the vehicle. This was the warranty replacement battery 1 yr. & 9 mos. ago. Greenville, SC, Lexus mgr. claims nothing wrong with battery. Says he won't replace battery even though it says 84 mo. warranty (Lexus 00544-MF24f-575). Says if he has to "replace a replacement," I have to pay for it. It's nighttime now, I'm over a barrel. I put out the $115+ for the new battery. I ask to hold onto the old battery. Dealer seems mildly shocked. Firm inadvertently(?) tries to charge battery recycling fee. While all this is going on, I decide to report the problem to Lexus' customer service line. Case manager won't be back to me for days. Phone lady politely suggests that I could request a loaner battery until this is resolved. Dealer refuses. I do the arduous drive back up the mt. I'm asking the same question you are. Something just doesn't "smell" right. I wonder if the dealer pawned off a used battery on me for the warranty replacement a year ago, which is why it went bad so fast. Or is there something amiss in the inherent electrical system that Lexus is failing to own up to?
