Overview of M240i

The BMW M240i is a powerful and sporty coupe that is known for its impressive performance and handling. It is equipped with a turbocharged 3.0-liter six-cylinder engine that delivers 382 horsepower and 369 lb-ft of torque, making it capable of accelerating from 0 to 60 mph in just 4.2 seconds.

This car is also available with xDrive all-wheel drive, which provides excellent traction and stability in all weather conditions. The M240i comes with an eight-speed automatic transmission that provides smooth and precise shifts, and it also features a sport-tuned suspension that delivers a responsive and engaging driving experience.

The M240i is not just about performance, however. It also comes with a range of advanced features and technologies that enhance comfort, convenience, and safety. These include a premium sound system, a navigation system, a rearview camera, and a range of driver assistance features such as lane departure warning and forward collision warning.

Engine Reliability

The BMW M240i comes equipped with a B58 engine, which is widely regarded as one of the most reliable mass-market engines in the US. The B58 engine is a turbocharged 3.0-liter inline-six that produces 335 horsepower and 369 lb-ft of torque.

One common issue reported by some B58 engine owners is low coolant levels in the main tank. While this issue is not unique to the M240i, it is important to keep an eye on coolant levels and address any leaks or issues promptly to avoid engine damage.

Overall, the B58 engine has shown impressive reliability, with many owners reporting no significant issues even after several years of ownership. Regular maintenance, such as oil changes and tune-ups, can help ensure the longevity of the engine.

It is worth noting that the M240i’s engine comes with a factory warranty of 4 years or 50,000 miles, whichever comes first. This warranty can provide peace of mind for owners concerned about potential engine issues.

Transmission Reliability

The M240i comes with an eight-speed automatic transmission as standard. While the transmission is generally reliable, some owners have reported issues with rough shifting and hesitation during acceleration.

According to the BMW owner forums, the most common transmission problem is a delay in shifting from first to second gear. This issue can be resolved by resetting the transmission control module or updating the software.

Another issue reported by some M240i owners is a clunking noise when shifting gears. This can be caused by a faulty transmission mount, which should be replaced by a qualified mechanic.

Suspension and Brakes Reliability

The BMW M240i xDrive Coupe boasts a well-tuned suspension and powerful brakes. According to several reviews, the suspension and brakes of the M240i are reliable and perform well even in demanding driving conditions.

The M240i’s suspension system is composed of MacPherson struts in the front and a multi-link setup in the rear. The system is designed to provide a balance between comfort and sportiness, and it delivers a smooth ride on most road surfaces. The suspension system also features adaptive dampers that adjust the suspension’s stiffness based on driving conditions, providing a more comfortable ride during normal driving and a more dynamic ride during spirited driving.

The M240i’s brakes are also reliable and powerful, thanks to its large brake rotors and four-piston calipers in the front and two-piston calipers in the rear. The brake system is designed to provide consistent stopping power even during high-speed driving and spirited driving.

Interior and Electronics Reliability

The interior of the 2022 BMW M240i is well-built and features high-quality materials. However, some owners have reported issues with the electronics system, particularly with the infotainment system.

According to some reports, the infotainment system can be slow to respond or may freeze altogether. Additionally, some owners have reported issues with the sound system, including blown speakers and malfunctioning amplifiers.

Despite these reports, the M240i has generally been praised for its interior and electronics reliability. BMW has a reputation for building high-quality vehicles, and the M240i is no exception.

Owners can take steps to ensure the longevity of their vehicle’s electronics system by following the manufacturer’s recommended maintenance schedule and avoiding harsh driving conditions that could damage the vehicle’s sensitive electronics components.

Safety Features

The BMW M240i comes equipped with a range of safety features that are designed to keep the driver and passengers safe in the event of an accident. These features include:

  • Airbags: The M240i comes with front, side, and knee airbags for the driver and front passenger. Additionally, there are side curtain airbags that deploy from the roof to protect the heads of all occupants in the event of a side impact.
  • Anti-lock Braking System (ABS): ABS is a standard safety feature on the M240i. It helps prevent the wheels from locking up during hard braking, allowing the driver to maintain control of the vehicle.
  • Electronic Stability Control (ESC): ESC is another standard safety feature on the M240i. It helps prevent the car from skidding or sliding out of control during sudden maneuvers or on slippery roads.
  • Traction Control: Traction control is also standard on the M240i. It helps prevent the wheels from spinning during acceleration, providing better grip and stability.
  • Adaptive Headlights: The M240i comes with adaptive headlights that adjust the direction and intensity of the light based on the car’s speed and steering angle. This helps improve visibility and reduce the risk of accidents at night.
  • Parking Sensors: The M240i comes with front and rear parking sensors that help the driver maneuver the car in tight spaces. The sensors emit a warning sound when the car gets too close to an obstacle.
  • Rearview Camera: The M240i also comes with a rearview camera that provides a clear view of what’s behind the car when backing up. This helps the driver avoid collisions with stationary objects or pedestrians.

Maintenance and Repair Costs

When it comes to owning a BMW M240i, maintenance and repair costs are an important consideration. The M240i is a high-performance vehicle, and as such, it requires specialized care to keep it running at its best.

According to RepairPal, the average annual repair cost for luxury compact cars is $801 per year. This includes both major scheduled maintenance and unscheduled repairs. The BMW M240i falls within this category, and while it may be on the higher end of the cost spectrum, it is not unreasonable for a luxury vehicle.

It’s important to note that the cost of maintenance and repairs can vary depending on several factors, such as the age of the vehicle, mileage, and driving habits. Regular maintenance is crucial to keeping the M240i running smoothly and preventing costly repairs down the line. BMW offers a complimentary maintenance program for the first three years or 36,000 miles, which covers basic maintenance such as oil changes, brake pads, and wiper blades.

After the complimentary maintenance program expires, owners can expect to pay for routine maintenance such as oil changes, tire rotations, and brake pad replacements. These costs can vary depending on the service center and location. However, BMW’s reputation for quality and reliability means that repairs tend to be less frequent than with other luxury brands.

In terms of repair costs, owners of the M240i can expect to pay more than the average luxury compact car. However, the car’s performance and handling make it a worthwhile investment for those who prioritize driving experience. It’s important to note that some repairs may be covered by BMW’s warranty, which lasts for four years or 50,000 miles.

Longevity of M240i

The BMW M240i is a high-performance sports car that has been on the market for a little over two years.

According to some owners, the M240i has been reliable so far, with no major issues reported. However, it is important to note that the car is still relatively new, and it will take some time before any long-term issues start to emerge.

One of the key factors that contribute to the longevity of the M240i is its high-quality construction. The car is built with high-quality materials that are designed to withstand the rigors of high-performance driving. Additionally, BMW has a reputation for building reliable cars, and the M240i is no exception.

Another factor that contributes to the longevity of the M240i is its regular maintenance. Like any car, the M240i requires regular maintenance to keep it running smoothly. This includes oil changes, tire rotations, and other routine maintenance tasks. By following the recommended maintenance schedule, owners can help ensure that their M240i lasts for many years to come.
