The third-generation Continental GT moved to the Porsche-derived MSB platform, bringing a significant leap in dynamics and refinement over its predecessor. The 4.0-litre twin-turbo V8 produces 542 hp and pairs with a smooth ZF 8-speed dual-clutch gearbox, offering a compelling alternative to the W12 with notably better fuel economy. It remains a handbuilt luxury grand tourer with Bentley's signature interior craftsmanship and a broad spread of torque.
Robust V8 engine, proven platform
Lower running costs than W12 variant
Air suspension repairs are costly
Complex electronics, expensive labor
Buy if: You want a handbuilt luxury GT with a proven powertrain and can budget for specialist maintenance and occasional high-cost suspension or electrical repairs.
Avoid if: You are not prepared for Bentley-level parts and labor costs, or you need a car that can sit unused for weeks without battery management.
Expected Annual Maintenance Costs
Common Problems
Air struts can develop leaks, causing uneven ride height and overworking the compressor · more· less
The Continental GT Mk3 uses an advanced air suspension system with electronically controlled dampers. Over time, the air spring bladders can develop leaks, causing one corner of the car to sit lower than the others, particularly noticeable after the car has been parked overnight. If a leaking strut is not addressed promptly, the compressor works overtime to compensate and can burn out. Individual OEM air struts cost approximately €1,200-2,000 each, with labor adding €500-800 per strut. A failed compressor adds another €1,500-2,500 including labor. In a worst case, replacing multiple struts and the compressor can exceed €8,000. Suspension warranty claims accounted for more than a third of extended warranty cases according to MotorEasy data. The issue typically develops after 60,000-80,000 km or 5-7 years. Early detection through checking ride height after overnight parking is key.
The signature three-sided rotating dashboard display can jam or fail to rotate · more· less
The Mk3 Continental GT features a unique three-sided rotating display panel in the centre of the dashboard. It contains 40 moving parts including two motors and a dedicated ECU. Owners have reported the display failing to rotate, getting stuck between positions, or producing grinding noises. A basic software reset (pressing and holding the volume button for 10 seconds) sometimes resolves the issue. When hardware failure occurs, the repair is more involved as the entire display module may need replacement. Bentley dealer quotes for the complete unit including labor range from €3,000-5,000. Independent specialists may manage €2,000-3,000 if only the motor or ECU is faulty. This is relatively uncommon but is unique to this generation and has no equivalent on competing cars.
Wiring harnesses can become trapped or snagged, leading to short circuits and warning lights · more· less
In July 2019, Bentley issued a recall affecting approximately 800 Continental GTs for wiring looms that could become trapped or snagged during manufacture, leading to chafing and potential electrical short circuits. Even on cars where the recall has been completed, the dense wiring throughout the car can develop issues over time. Symptoms range from intermittent dashboard warning lights to complete failure of specific systems like heated seats or window motors. Diagnosis is often the most expensive part, as tracing a wiring fault in a Bentley requires specialized equipment and expertise. Most repairs cost €800-1,500 at an independent specialist, but complex faults requiring harness replacement can reach €3,000.
Frameless window motors fail with a characteristic hissing sound before complete failure · more· less
The Continental GT uses frameless windows that must drop slightly when the door opens and rise when it closes. The window motor and ECU are integrated as a single unit, and Bentley does not supply the motor separately. When failure begins, a hissing sound is audible during window operation. Eventually the window will fail to operate entirely or may drop into the door. The integrated motor-ECU unit costs approximately €400-600 per window, with labor adding another €400-600 due to the complexity of the door mechanism. This is a known weakness across all Continental GT generations and typically affects at least one window over the life of the car.
Multiple electronic modules continue drawing power when parked, draining the battery within days · more· less
The Continental GT has an extensive network of electronic modules that can continue drawing current even when the car is shut down. If the key fob is stored nearby, the car may wake periodically to prepare for starting, accelerating battery drain. Owners who do not drive their car regularly report flat batteries within 5-10 days. The dual-battery system means that sometimes only one battery fails while the other remains functional, causing confusing symptoms like a working dashboard but no engine cranking. A quality battery conditioner or trickle charger (CTEK MXS 5.0 or similar) is essential for any Continental GT that is not driven daily. Replacement batteries for the Continental GT cost €150-300 each.
Oil feed strainer to turbos can clog over time, risking turbo starvation and failure · more· less
The 4.0-litre V8 engine shares its architecture with the Audi S6/S7/RS6 engine family. An Audi TSB (2044640) documented a problem where a small oil strainer feeding the turbochargers can become clogged, starving the turbos of oil and leading to catastrophic failure. This issue was most prevalent on 2012-2017 models, and published data suggests less than 4% of Continental GT V8s experienced turbo failure. The Mk3 (2018+) benefits from an updated strainer design, making this less likely but not entirely eliminated. Preventive replacement of the strainer costs approximately €1,500 including labor (significant access difficulty). If the turbos have already been damaged, full replacement can reach €6,000-8,000. Regular oil changes every 10,000 km with quality synthetic oil significantly reduces the risk.
Well-engineered but expensive when things go wrong
The Mk3 Continental GT V8 benefits from the modern MSB platform shared with the Porsche Panamera, and the 4.0 V8 is a proven engine across the VW Group. Most issues are related to the air suspension system and electrical complexity rather than fundamental powertrain problems. However, Bentley labor rates and parts costs mean even minor repairs carry premium price tags. A complete service history from a Bentley dealer or recognized specialist is essential, and a battery conditioner should be considered mandatory equipment for any car not driven daily.
