2016 Toyota Land Cruiser Pricing and Specs

I don’t think this is an isolated problem, Andrea, as I’ve heard of exactly the same thing happening to other 200-Series Toyotas. From the look of things, this type of recurring limp-home-mode problem with the LandCruiser is usually down to one of three things.

The first is a damaged or faulty stepper motor which controls both the throttle and the variable vanes on the turbocharger. Sometimes the vanes can become stuck, refuse to budge and burn out the stepper motor’s electronics in the process. If there’s a problem with any of those components, the stepper motor – at the very least -t will need to be replaced. The advice there is to use the genuine Toyota part, not a cheaper copy.

The second possibility is a fault with the EGR valve, and the third is a faulty accelerator pedal which, unlike older cars, does not connect via a cable to the throttle, but ends an electronic signal to the car’s computer. Any glitch here can send the car into limp-home. The fact that you’ve had problems while in cruise control makes me suspect either the accelerator or stepper motor, so they’d be the components I’d be checking first. For what it’s worth, I reckon the police-scanner explanation is a load of rubbish.

Was it a Toyota unit or an aftermarket one? If it was a Toyota one I would request the dealer to update the maps to then latest available, and I would expect them to do that at no cost to your son. If it was an aftermarket unit fitted by the dealer then Toyota is not responsible for it, and you have to talk to the dealer as the person who installed the unit.

200-Series owners commonly report the vibration you are experiencing. There was talk of revised engine mounts, but it's unclear if anything was released. We'll check with Toyota.
