What Problems Does the 2018 BMW 6 Series Have?
Frequently reported problems for the 2018 BMW 6 Series, like many modern BMWs, often revolve around electrical systems and the iDrive infotainment system. Some owners have reported issues with sensors, control modules, and the overall responsiveness of the iDrive interface. Oil leaks are another potential concern, particularly as the vehicle ages, especially in the V8 650i models. These leaks can stem from valve cover gaskets or other engine seals. It's important to maintain proper fluid levels and address any leaks promptly.
Suspension components, such as bushings and struts, may also require attention over time, particularly on vehicles driven on rough roads. Check for unusual noises or vibrations during a test drive. While not specific to the 2018 model year, BMWs in general can have cooling system issues, so inspect hoses, the radiator, and the water pump for any signs of leaks or damage.
Recalls can be checked through the National Highway Traffic Safety Administration (NHTSA) website using the VIN. Regularly checking for recalls is crucial, as these address safety-related defects. Long-term reliability can be improved with meticulous maintenance, including timely oil changes, fluid flushes, and inspections.
