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.

Who can I contact if I’m worried about my Lexus?

  1. Hello
    My catalytic converter of RX400h was stolen a day ago. I didn’t know it until police informed me this morning!
    I read all the comments here and note it’s a significant issue for this type of models.

    Why didn’t Lexus warn owners of this specific model as they are at higher risk?(Acknowledge other models are also at risk).

    Please warn relevant owners asap to take practical precautions and to minimise the risk of it happening again!

    Thank you

        1. Hi Samson,

          Thanks for getting back in touch. We don’t currently offer a Catloc device for any Lexus vehicles, however we are urgently seeking other technical solutions to help our customers.

          Thanks.

      1. I have just had the catalytic converter stolen off my car in a busy car park.
        I have been advised that this could happen again once replaced is there anything I can do to prevent this.

        1. Hi Anna,

          Thanks for getting in touch. We are so sorry you have been impacted by this crime. We have Catlocs available for RX400h and the Lexus CT and we would recommend contacting your nearest Lexus centre for more information.

          Thanks.

      2. Hi, yesterday they stole my catalytic converter for the 2nd time and I would like to part exchange for another Lexus however will the newer model NX or RX be open to cat theft as well?

        1. Hi Tijen,

          Thanks for getting in touch. We are so sorry you have been a victim of this crime. In theory, any car with a catalytic converter is at risk of this type of theft. However, we are producing Catlocs for vehicles deemed most at risk and we currently don’t produce them for either the current generation RX or NX.

          Thanks.

      3. Happened to me too. Both the dealer and insurance company knew about the rise in theft but didn’t inform owners. Nor is lexus paying for fitting a cat lock for this design oversight. Unlikely to buy another lexus. So much for customer service.

        1. Hi SM,

          Thanks for getting in touch. We are so sorry you have been affected by this crime. We have tried to ensure as many of our customers as possible are aware. We published police advice on this crime as soon as it could online, wrote to our dealer network to brief customers and wrote directly to owners of a number of our vehicles where we had details to do so.

          Currently, we are also engaging with Home Office, Local MPs, Met Police (OVCU) and the Assistant Chief Constable of Cheshire Police (Jenny Sims) who is also the National Lead for all vehicle crime. All of this will raise the profile of this crime with all police forces and identify issues with current legislation.

          If you would like to discuss your situation further with our customer relations team, you can find the contact details here: https://www.lexus.co.uk/concierge-tool/contact-us/

          Thanks.

          1. Hello,
            I have a 2012 ct200h. Should I worry about my catalytic converter? Do I need to have a catlock fitted?

          2. Hi,

            We have developed a Catloc for this vehicle. It can be bought and fitted for £250 including VAT. Please contact your nearest Lexus centre to get one fitted.

            Thanks.

    1. Hi Samson,

  2. My Mum (who has a Lexus service plan) has just had her catalytic convertor stolen today from her Lexus RX400h in a supermarket car park. We are also baffled why she has never had an email from Lexus warning of this awful crime! I have put her email and name in the contact box. Could customer relations please get in touch with her ASAP please.

    1. Hi Moira,

  3. catalytic converter of RX400h was just 12 hours ago, i just parked my car and came back after 15-20 minutes and catalytic converter gone already , they are very professional to steal it.

  4. I have just been a victim of this awful crime, completely gutted that my lovely car has been stolen from, not to mention the cost of putting it right, I was in a retail car park in Cheltenham, a place I visit often as down the road from where I work, I was only there 15/20 minutes max, can’t believe this has happened. Why have I not been warned

    1. Hi Lynn,

      Thanks for getting in touch. We are so sorry you have been a victim of this crime. Our customer relations team will be able to support you further in any way we can and we will email you directly to discuss this with you.

      Thanks.

  5. Hi
    You mention a specific Model and a Date range above so does this mean a new NX for example is not likely to be a “target” … and more to the point do the vermin doing this know that ?

    1. Hi Bill,

      Thanks for getting in touch. Due to the high-grade power saws used to remove the catalyst, in theory any car with a catalytic converter is at risk of theft.

      Thanks.

  6. It’s not just Lexus, this is a huge problem that’s not going away. The UK police need to do more in general. SInce October 2019 we have had our cat stolen from our Honda CR-V twice and also our Honda Civic THREE ATTACKS! We have lost both our cars and are being forced to change our plans and move house to escape the fear of being targeted a fourth time.They just wont leave us alone. It’s meant I will likely have to close my business for moving. Utter disgust for the pieces of filth who freely conduct themselves in this cowardly and sensless way. Spineless.

  7. I had my stolen on the 10th
    I have had to go through my insurance company! Now I’m worried about it happening again! Once my car is fixed and returned
    Please can you advise on the best catalytic prevention system on the market ? There’s so many and I don’t want to buy a load of rubbish that’s won’t work!
    Many thanks

    2. We feel exactly the same – we had ours stolen in the last 24 hours but reluctant to spend the money on a new one in case they come back.

      1. Hi There,

        Thanks for getting in touch with us about this. We are so sorry you have been a victim of this crime. We will email you directly in order to gain additional details and put you in touch with our customer relations team.

        Thanks.

  8. RX400h driver here, CAT stolen on 5th November 2019. Replaced via Insurance and 9 days after the car is returned to me the CAT stolen again yesterday. This is epidemic levels yet no-one can provide a viable deterrent. The irony here is that most of the precious metals in these stolen CATs ends up back in new CATs. Come up with a better location for the CAT or a better solution, not just ‘contact your local Lexus service centre’.

    1. Hi There,

      Thanks for getting in touch. We are incredibly sorry to hear about this. We will email you directly in order to gain additional details of your situation in order to put you in touch with our customer relations team who will be able to help you further.

      Thanks.

  9. Lexus as usually skyrockets the prices for everything done at their centre, £750 is that no profit to Lexus ? They are laughing on us, people stop using them unless it’s a minor service, they are the biggest thieves.
    They tried to charge me over £6000 for what’s at local garage £600.
    My catalyst converter stolen today, local garage supplies and fits Chinese catalyst converter on the day for £250

    1. Hi Alex,

      Thanks for getting in touch. We are so sorry to hear about this. We would like to help you further by putting you in touch with our customer relations team. They are best placed to discuss your situation with you in more detail and provide you with support in any way we can. We will email you directly in order to gain additional details and open a case with them on your behalf.

      Thanks.

    2. Hi Alex,

      Could you please give me the details of your garage? I am going through the same issue and it is very expensive to fix at Lexus.

    3. HI Alex. Can you advise if the aftermarket Chinese catalyst dies the same job as an original one. Any nloises or rattling when driving ?Would you still have a catlock fitted on it? Thanks

      1. Hi Robert,
        Thanks for your comment.
        We would only recommend using genuine Lexus parts as they have been created specifically for the protection of the vehicle.
        Thanks.
