Hi guys, my name is Nads and I'm based in Havant, Hampshire. I picked up a 2007 RX350 with 90k miles on the clock at the start of lockdown and despite being a massive Honda fan with an S2000, I've found myself increasingly obsessed with Lexus products!
I've searched around the forums but I'd appreciate any advice people have regarding a problem that has appeared today.
The car took a while to fire up this morning but it started and made a low frequency beep for 3-4 seconds on startup. No clear warning lights. After that it started normally each time I tried. When I tried the car again later on it cranked but would not start. It just sort of tailed off and died. On second attempt it started normally and after that it fires up really quickly with no noises.
I've just tried again this evening and it did the same thing where it cranked slowly then died. Again the car then behaved normally. I've tried it with 2 different keys so it's not an immobiliser issue. The car shows no signs of any engine weakness when driving and has never broken down.
I find myself doubting it's the battery as the car has shown no gradual signs of starting poorly and is used almost every day. I'm wondering if this sounds like a crankshaft position sensor or something else. Does anyone here have experience of this happening?
Thanks,
Nads
