Hello! I'm new to this forum, so thanks for having me. Bought a 2014 Lexus IS350 F-Sport AWD with 60k miles last month and started having problems last week. Also, it may be important to note that I live in upstate NY and the weather has been in the 20s/30s. Also, the closest Lexus dealer is about 1.5hr away. Here's a rundown of what's going on:

Was sitting in parking lot with power on and engine off for 3-5 minutes. Went to start engine and heard nothing but rapid clicking noise. Waited 10 minutes and tried again with same noise. Called for a jump start, guy came and helped me jump my car with success, took the car to AutoZone to have the battery tested. The battery appears to be the original Lexus battery and tested with full power and 100% charge. They also tested the alternator which appeared to be in full working order as well. Went to start car again and it started right up with no issues. However, now there is a check engine light on since jump starting the vehicle, code comes up for camshaft positioning sensor, after starting the engine again.

Similar thing happened yesterday. However, this time I started the engine with no issues, shut the engine off 2 minutes later. Went to start the engine 5 minutes later, same rapid clicking noise. I then spent the day switching out all 6 spark plugs which appeared worn out. This morning, the car seemed to struggle to start but did successfully.
Any ideas what could be going on? I appreciate all the responses. Thanks!

Best tip :

Unplug the - buttery for 10 minutes .. your ECU will resets all data .. and hope you problem gone after that

battery issue. take it to a dealer & have them update your ecu and replace battery

Thanks for the responses. I will certainly try unplugging the battery and letting the ECU reset.

I did this procedure and started it up. The engine did seem to struggle to start. We'll see how it goes in the coming days. I might stop by another autozone to get the battery tested again.

I disconnected the battery on my '14 is350 the other night to install a intake and when I went to restart the car for the first time after getting everything buttoned up it struggled a little. The car actually stalled. After that first hiccup there have been no problems. Car has started every time since no problem. Maybe just give your ecu a few minutes to learn.

Sounds like a text book dead/dieing battery. I know the some 2014s had issues with batteries going flat abnormally. Forget the garbage factory battery. If they don't give you one for free after the ECU update, which they will give you for free. Go order one of these bad boys. Optima red top

Agreed here. I have always had the experience that the factory batteries are junk.
