Common Bentley Problems

Built on a new platform shared with the Porsche Panamera, the Mk3 is a massive leap forward in technology and reliability, though electronic complexity is at an all-time high.

Bentley's first SUV. While very capable, it suffers from typical high-end SUV issues like heavy tyre/brake wear and complex air suspension faults.

A significant refinement of the original GT, introducing the V8 engine option. While generally more reliable, it still shares the heavy-wear characteristics of its predecessor.

The Bentley Mulsanne, produced from 2010 to 2020, was the final flagship to be handcrafted entirely at Bentley’s headquarters in Crewe, successfully preserving the brand’s traditional "hewn from granite" feel. Avoiding the shared Audi/VW platforms used in the Continental GT range, the Mulsanne utilized a bespoke chassis and the iconic 6.75-litre "L-Series" V8 engine—a lineage stretching back to the 1950s. In the UK, it represents the absolute pinnacle of British luxury, prized for its peerless "waftability," hand-stitched leather interior, and a level of road presence that establishments it as a more characterful and bespoke alternative to the Rolls-Royce Ghost. Reliability for the Mulsanne is generally high for a hand-built car, reflecting the under-stressed nature of its massive V8 engine, but used buyers must navigate specific high-cost maintenance themes. The most common technical concern involves the air suspension system, where rubber air springs can perish or connecting lines can crack over time, often resulting in an uneven ride height and expensive corner repairs. Additionally, due to the vehicle’s immense 2.7-tonne weight, it is exceptionally hard on its braking and suspension components, with front discs and bushes being common MOT failure points. Owners also report occasional "gremlins" in the earlier infotainment systems, including Bluetooth connectivity glitches and slow radio reception. When buying a used Mulsanne in the UK, a full Bentley or recognized specialist service history is absolutely non-negotiable, as missing a scheduled service on such a complex vehicle is a major red flag. Prospective owners should listen for any "whining" from the power steering pump and check for misting in the front sidelight units after a test drive. It is also vital to check the deep, hand-finished paint for "swirl marks" and verify that the 12V battery is healthy, as these cars are highly sensitive to low voltage. A well-maintained Mulsanne remains one of the most prestigious and rewarding luxury vehicles on the used market, offering a unique "Old World" charm that no modern, mass-produced SUV can replicate.

The four-door sibling to the Continental GT. It shares nearly all mechanical components and therefore the same common faults, with additional complexity in rear cabin electronics.

The car that redefined Bentley. While now offering incredible value, early Mk1s can be "ticking time bombs" of maintenance if vacuum pipes and air suspension have been neglected.
