Has anyone experienced inserting their key only to be told that the engine is immobilised? It happens on really hot days when the car has been parked in the sun and it will start eventually after 5 or 6 attempts at locking up, unlocking, then trying again.

Service tech said that there were many "under-voltage" errors in the ecu's log and it did have some corrosion on the terminals but even after cleaning and re-setting - same again.

The steering column gets so hot in the sun that the key would almost be too hot to touch even after only being in the ignition socket for a couple of minutes.

I know the factory batteries are crappy and this one's a year old - but want to put off investing in a $220 Calcium battery quite yet.

I have thought of a hundred possible causes but I am really looking for someone that has the same symptoms rather than just more suggestions at what it might be. If I attempted all of my own suggestions I would spend thousands and still not guarantee a fix.

So your aware of the under voltage codes, and even after resetting they come back...

And leaving the car in the sun it gets HOT

Well solution is don't be a tight arse and buy steal or borrow a new battery

And get a $2 sunshade

I park my car in direct hot sun, the LCD screen was fading in the ctr dash cos it was so hot, a $2 sunshade fixed this and allowed me to also use the steering wheel cos I could touch that without burning my hands off...

Thx MexBat,

Not against buying anything if it will help but did not want to spend a cent if someone knew exactly what was rqd to fix it.

And yes will be getting a sunshade anyway (prob a few for the side windows too). I have put Calciums in my last 3 cars - they are actually great value for money.

But none of those cars ever gave up the ghost just cos it was a bit hot outside - my Land Cruiser never missed a beat even parked in 50 deg desert sun - I know I know FPVs are great but they are certainly no Toyota when it comes to robust reliability.

That said, I will certainly not swap my FPV for a Cruiser again quite yet....
