Toyota Hybrid Theft: What Taxi and PCO Fleets Need to Know in 2026

If you run a taxi or PCO fleet, there’s a good chance a lot of it is Toyota. TfL’s own data from January 2026 shows 23,262 Toyotas licensed as private hire vehicles in London, more than any other manufacturer, and the Prius on its own accounts for 8,047 of them. The Auris, Corolla and C-HR fill out plenty of the rest.

Toyota hybrids have had a rough reputation with thieves. A few years ago the worry was catalytic converters being cut off overnight. Today the picture is different, and it’s worth knowing what’s actually changed before you spend money protecting against the wrong thing.

Catalytic converter theft: much smaller than it was

Catalytic converters contain precious metals, and hybrids carry more than most cars because their exhausts run cooler. That made the Prius, Auris, Honda Jazz and Lexus RX favourite targets during the 2020 to 2022 spike, when cutting a converter off a parked car took a couple of minutes.

That wave has largely passed. A freedom of information request by Auto Express found that across the 30 police forces that responded, catalytic converter thefts fell from 6,909 in 2021 to 150 in 2024, a drop of around 98%. Police credit coordinated operations, a database for tracking stolen converters, and manufacturers forensically marking their parts.

So it’s not the threat it was. It hasn’t gone completely, though, and older hybrids like early Priuses and Aurises, which many PCO fleets still run, were always the most exposed. If you lose one, the car is off the road until it’s repaired, which for a working PCO car means lost earnings as well as the bill.

The bigger risk now: electronic theft of the whole car

The more serious problem for Toyota and Lexus owners in recent years has been theft of the entire vehicle by getting into its electronics. Thieves have targeted models such as the RAV4 and C-HR, along with several Lexus models, by gaining access to the vehicle’s wiring from outside the car, then unlocking and starting it without the key. It can be done quickly and quietly.

Toyota’s position is that the problem is organised gangs rather than a flaw in its security, and it offers some fixes through dealers, including a protective plate on certain models and a security upgrade on others. If you run affected models, ask your Toyota dealer what’s available for your vehicles.

Not every Toyota is equally exposed. The point for a fleet operator is that the factory key system isn’t something you should rely on alone.

How to protect a Toyota hybrid fleet

Fit an immobiliser

This is the layer that matters most against electronic theft. A ghost immobiliser needs a PIN entered on the car’s own buttons before the engine will start, so a thief who has fooled the key system still can’t drive away. On pool cars, a relay immobiliser with driver tags does the same job and records who had which car. Our comparison of ghost and relay immobilisers covers which suits your setup, and can a ghost immobiliser be bypassed is honest about its limits.

Track every vehicle, with alerts that matter

A tracker won’t stop a theft, but the right alerts change how fast you find out. Movement alerts overnight tell you a car is leaving a driver’s street at 3am. Tilt or tow alerts can flag a car being jacked up or lifted, which is what catalytic converter theft and flatbed theft both look like. For many newer Toyotas, digital tracking works without fitting anything. Older Priuses and Aurises usually need a hidden hardwired tracker. See where trackers should be fitted.

Think about where cars park overnight

PCO cars usually live at drivers’ homes, not in a depot. That makes parking habits part of your security:

• Park close to a wall or kerb so the underside is hard to get at
• Use well-lit spots, ideally overlooked
• Use a garage or private drive where there is one
• Keep key fobs well away from the front door, ideally in a signal-blocking box

Mark and protect the converter on older hybrids

For the hybrids most exposed to catalytic converter theft, a converter marked with a unique code is less attractive to steal and easier to trace. Some operators also fit a physical guard or cage. Ask your garage or installer what fits your models.

Use dash cams with parking mode

A 4G dash cam with parking mode can record and alert you to someone around or under a parked car. It won’t stop a determined thief, but it helps with the police report and the insurance claim. Check the camera has a battery cut-off so it doesn’t flatten the 12V battery. Our post on dash cam parking mode battery drain covers the settings.

What to tell your drivers

Most of this only works if drivers are on board. A short briefing covers it: where to park, where to keep the fob, how to check the car has actually locked, and who to call if the car isn’t where they left it. Put it in your driver handbook so new drivers get it from day one.

Frequently asked questions

Is catalytic converter theft still a problem in the UK? Much less than it was. An Auto Express FOI found thefts fell by around 98% between 2021 and 2024 across the police forces that responded. Older hybrids are still the most exposed, so basic precautions are still worth it.

Why were hybrids targeted for catalytic converters? Hybrid exhausts run cooler, so their converters contain more precious metal to work properly. That made the Prius, Auris, Honda Jazz and Lexus RX particular targets.

Which Toyotas are targeted for electronic theft? Reported targets include the RAV4, C-HR and several Lexus models. Toyota offers some protective measures through its dealers, so ask what’s available for your vehicles.

What’s the best protection for a Toyota taxi? An immobiliser to stop the car being started, tracking with movement and tow alerts, sensible overnight parking, and good key habits. On older hybrids, add converter marking or a guard.

How many Toyotas are PCO cars in London? TfL data from January 2026 showed 23,262 Toyotas licensed as private hire vehicles in London, with the Prius the single most common model at 8,047.
