Catalytic converter theft: what you need to know

Catalytic converter theft from cars isn’t a new crime, but it has increased significantly in recent times.

Police forces around the UK, including those in West Yorkshire, London and Nottinghamshire, are advising owners of any car fitted with a catalytic converter to take precautions.

Any car fitted with a catalytic converter within the exhaust system could be at risk. In the case of Lexus, we are aware that the second-generation Lexus RX 400h models (2005-2008) and the Lexus CT 200h have been a target for thieves.

Below we’ve gathered the best advice for Lexus owners who may be concerned.

What is a catalytic converter? 

The catalytic converter is part of the car’s emissions control system. It cleans up the exhaust gases before they are expelled from the car through the exhaust pipe. Its internal elements react with the gases, breaking them down into less harmful substances and water vapour. All cars sold in Europe since 1993 have had to be fitted with catalytic converter by law.

Why are they a target for thieves?

The police are best placed to offer advice on the motivation behind crimes. But we understand that the recycling value of catalytic converters is the primary attraction to thieves because it contains precious metals such as rhodium, platinum and palladium.

What is Lexus doing to stop its cars being targeted?

In May 2021, Lexus (GB) announced that it would be covertly marking more than 100,000 catalytic converters in order to combat theft. By working with police and Smartwater, catalytic converters can be tagged with an invisible yet traceable marking, meaning that a stolen catalytic converter can be traced to a specific crime, helping police in their attempts to fight the organised gangs responsible. It also raises the risk to all those handling the devices along the criminal chain, from theft to eventual disposal and recycling.

It is free to get the catalytic converter marked, all customers need to do is call their local Toyota or Lexus retailer to arrange a visit.

In addition to this, Lexus has issued 20,000 Smartwater kits to police to support their local anti-catalyst theft initiatives. The company is also working with the AA, Toyota’s roadside partner, so its patrols can point customers to where they can get a free kit.

We have also developed and reduced the price of a ‘Catloc’ device which can deter theft and make it more difficult. Lexus teams in the UK and other countries are urgently exploring new technical possibilities to deter criminals as well.

We are working with the police, as well as talking to government about changes in the law around scrap metal sales that would make it harder for criminals to sell stolen catalysts for cash.

However, these are criminal operations and our scope is therefore limited. A number of police forces are taking action and some forces, such as Nottinghamshire, are also starting awareness campaigns. It is vitally important for anyone who is a victim of this crime to report it to their local police force as quickly as possible.

In the main, it remains older cars that are targeted because advances in efficiency and technology mean the latest generations of Lexus catalytic converters contain vastly lower amounts of precious metals, whilst still doing their job just as well or even better; this means their value for recycling is very low and they are not attractive to thieves.

We’re doing all we can. We’ve shared police guidance with customers, and are seeking technical solutions, although for obvious reasons we would like to refrain from talking about specifics.

How much does it cost to replace a catalytic converter?

Our priority is to do all we can to support Lexus customers who have been the victims of catalytic converter theft.

We have reduced the prices of catalytic converters to a level where Lexus UK does not make any profit from their supply to customers.

Your nearest Lexus centre can advise on exact costs after inspecting your vehicle.

How long will I have to wait for replacement parts?

The rapid rise in this crime is one we could not have envisaged set against many years of low incidence of thefts. It has impacted our ability to source a sufficient quantity of replacement parts, for which we sincerely apologise.

However, we are taking urgent action with our suppliers to secure increased supplies, which we hope will allow us to effectively tackle the supply issue and repair customers’ cars more quickly.

  1. I had the misfortune of having my CC stolen from my 2007 RX400h. I visited a garage who replaced it for £150, but only because they they happened to have an after market one lying around. I also bought a 2014 RX450h last year from a Lexus Dealership who informed me when I asked for the catlock to be installed that these vehicles were not susceptible to the theft. I didn’t quite believe it then, and I am less convinced now.

    The thing I will say is that Lexus should be offering at at least 50% new catlocks to show they want to assist customers, considering I have now been quoted £400 for parts and labour to fit one.

    1. Hello Ishfaq,
      Thank you for contacting us. We’re sorry to hear that you have been affected by this awful crime.
      Any vehicle containing a catalytic converter is in theory at risk of theft due to the precious metals these contain.
      CatLocs are available for both of these vehicles, and they can be ordered through your nearest Lexus Centre. These are produced at zero profit to Lexus UK.
      Smartwater marking is also available, and this can be carried out free of charge at your Lexus Centre.
      If you would like to make a formal complaint, you can do so with our Customer Relations team here: https://www.lexus.co.uk/concierge-tool/contact-us/.
      Once again, we’re so sorry to hear that your vehicle has been targeted by thieves. We hope you’re back on the road soon.

    1. Hello Bhavin,
      Thank you for contacting us.
      There is no official Lexus CatLoc available for the IS300h.
      However, Smartwater marking is available for all vehicles. This involves tagging catalytic converters with an invisible yet traceable marking, meaning that a stolen catalytic converter can be traced to a specific crime, helping police in their attempts to fight the organised gangs responsible. It also raises the risk to all those handling the devices along the criminal chain, from theft to eventual disposal and recycling. This can be carried out for free at your nearest Lexus Centre.
      Thanks.
