Around this time, Toyota (and others) was having terrible problems with paint peeling and flaking off its cars. My best information suggests that there was a problem with the paint supplier’s quality, and the result was paint that was absolutely falling off affected cars, sometimes in sheets. White cars seemed to be the biggest offenders, but other colours were affected, too.

With that in mind, I’d be taking the car to a paint specialist who will be able to determine if your car is one of the affected ones or not. If not, then you may indeed have paint damage due to water sitting on the paint, but that seems a fairy remote possibility if the car has been garaged most of its life. If the cause is a case of the paint quality problem, then you need to talk to Toyota Australia’s customer service department. Even though the car is out of warranty, this may be classed as a pre-existing problem and subject to some form of warranty claim. That said, I wouldn’t be holding my breath…

Simply assuming the problem is a dud sensor is a great way to replace a bunch of things that weren’t causing the problem. This needs to be diagnosed and the first step there is to have the car electronically scanned to see what faults the computer already knows about. From there, you can make a much more informed plan of attack.

That said, you may well be right and the problem is a crank-angle sensor or something to do with the throttle position sensor. But, equally, the problem could be with the car’s wiring (getting hot when the power is turned on) or the fuel pump, so making a guess and replacing that component is a great way to waste time and money. A scan is quick and cheap and the smart way to go on any electronically fuel-injected vehicle.

Plenty of used cars change hands without service books in the glovebox. But this is usually a problem in older cars where the vehicle is well and truly out of warranty. In a newer cars such as yours, the lack of any service history in the car would be a major red flag.

There’s no law requiring a car dealer to provide a service history, just as there’s no law compelling owners to have their cars serviced correctly, even though failing to do so will often void the car’s warranty. And how can a dealer be responsible for a car’s service books if the previous owner lost them? Also, if the car hasn’t been serviced within the Toyota dealership network, how can a dealership determine what that service history has been?

But here’s what’s probably happened: Many dealerships (especially high-volume ones) remove the service handbook, owner’s manual and the second key from the car before it goes on the lot. That’s to prevent those things going 'missing' over the weeks the car is on sale and being test driven by who-knows-who. In my experience, there will be one person at that car-yard who will know where the books and keys and stored and until you find that person, their location will remain a mystery. But, if the car was bought on the condition that the service books would be sent to you, then that forms part of the contract of sale and the car-yard must produce them. In the meantime, since you don’t know when the last service was carried out, I’d be pushing for a free service to ensure the car doesn’t wind up with a skipped service based on time and kilometres.
