McLaren servicing

McLaren values customer feedback and actively uses it to improve their vehicles. Customer input regarding engine faults is taken seriously, and the company addresses reported issues through software updates, technical service bulletins and improvements in subsequent models.

Please contact us if you require service bulletin information for your vehicle or software updates.

While some modifications may enhance performance, for cars still in manufacturer warranty it is crucial to approach engine modifications with caution. Unauthorised modifications can void warranties and may introduce unforeseen complications. McLaren recommends consulting authorised dealerships or the manufacturer before making significant modifications. For cars out of warranty we strongly advise a full inspection of the vehicle to assess the need for pre-emptive work, including upgraded components.

McLaren, like any manufacturer, continuously evolves its models and addresses reported issues with a focus on improvement. The timeline can vary, but McLaren is committed to resolving issues promptly and ensuring subsequent models benefit from lessons learned.

Owners can stay informed by checking for communications from the manufacturer, and from us here at SBR Engineering. McLaren typically issues notifications directly to owners, and authorised dealerships and ourselves can provide information on available software updates or improvements. Owners can also use the online portals provided by the manufacturer.

McLaren road cars are generally well regarded for their performance and improving reliability. While some models have encountered specific issues, the brand is committed to continuous improvement: it listens to customer feedback, implements software updates and introduces enhancements to ensure the reliability and longevity of its road car engines.

Regular and proactive maintenance is crucial in helping prevent potential engine faults. Adhering to scheduled service intervals, conducting routine check-ups and promptly addressing any warning lights or unusual sounds all contribute to the health and longevity of the McLaren engine. However, we are still seeing excessive wear on older cars, even with a faultless service history.

McLaren provides a comprehensive warranty for its road cars, typically covering the engine and associated components. The specific terms vary by model and region. Owners should familiarise themselves with the warranty terms, as fixing faults not covered can be expensive. SBR are able to offer a warranty for McLaren models after a full inspection of the vehicle.

McLaren has been proactive in addressing reported engine faults. When issues arise, McLaren's engineering team release software updates, implement improvements in subsequent models and offer solutions to affected owners. Unfortunately the dealer network has not always delivered the customer service the manufacturer might have hoped for.

Regular maintenance and adherence to service schedules play a crucial role in preventing potential issues. Here at SBR we are able to offer the same software updates if needed, with our factory diagnostics.

McLaren road cars, while renowned for their high-performance engines, have experienced some recurring issues over the years. Common faults include the cooling system, electronic glitches and software-related issues. Some models have also faced overheating and engine misfires, which can be caused by mechanical failure.

The MP4-12C faced teething problems related to electronic glitches and software, and the M840T engine in the 720S had occasional reports of overheating and misfires. Early versions of the M838T also suffered from valve train wear; this was addressed on later engines but still affects the earlier versions. Both engine versions have suffered from cylinder liner issues and even con rod failure.
