Lexus has confirmed the remedy for a recall covering 789 of its flagship SUVs, and for some owners it means a brand-new engine. The action covers the Lexus LX 600 and the GX550, both fitted with the same twin-turbo 3.4-litre V6.
What is wrong
Lexus says the engines may contain machining debris left over from production, which can contaminate the bearings. In the worst case that leads to engine knocking, rough running, a no-start, or the engine stalling while driving. Affected LX600 models were built between 16 November 2022 and 1 April 2024, and GX550 models between 4 March and 3 April 2024.
What owners do
Lexus dealers will inspect the engine, a job of about two hours, and will only replace it if the inspection finds a problem. All work is free. Owners can check whether their VIN is included by contacting a Lexus dealer or the Lexus Customer Assistance Centre on 1800 023 009.
Cartell Assessment
The numbers are small, but the potential failure is not, and replacing an engine is about as serious as a remedy gets. Lexus finding the issue and covering the fix in full is the right call.
AU Outlook
Debris-related engine recalls have hit several brands running high-output turbo engines, so expect more scrutiny of forced-induction petrol V6s. If you own an affected LX or GX, book the inspection now rather than waiting for a symptom.
