Vehicle History Report
What Problems Does the 2021 BMW 4-Series Have?
As a relatively new generation for 2021, long-term reliability data is still accumulating. However, early reports and general BMW trends can offer insights. One of the most discussed aspects, though not a mechanical problem, is the polarizing design of the large kidney grille, which some find aesthetically displeasing. In terms of mechanical issues, there haven't been widespread, model-specific, commonly reported catastrophic failures for the 2021 4-Series. However, as with many modern luxury vehicles, potential areas for concern in the longer term could include the complex electronic systems and infotainment hardware.
Specific to the 2021 model year, there have been some recalls issued. For instance, a recall was issued concerning the automatic emergency braking system, which might not function as intended. Another recall addressed potential issues with the seat belt pretensioners. These are not necessarily indicative of poor overall reliability but are important to be aware of, as all vehicles can experience recalls. Owners have also reported occasional glitches with the iDrive infotainment system, such as freezing or connectivity issues, though these are often resolved with software updates.
Regarding long-term durability, BMWs are generally built to last with proper maintenance. However, the cost of repairs for components like the turbocharged engines, complex transmissions, and advanced electronic systems can be higher than for non-luxury brands. Specific to the 2021 4-Series, its powertrain options are generally robust, with the inline-4 and inline-6 engines having proven their mettle in other BMW models. The mild-hybrid system in the M440i adds another layer of complexity that could potentially become a point of failure down the line, though it's too early to confirm significant issues. Owners who adhere to the recommended maintenance schedule, including regular oil changes, fluid flushes, and inspections, are likely to experience good long-term reliability.

How Does the 2021 BMW 4-Series Compare to Other Vehicle?
The 2021 BMW 4-Series competes in the fiercely contested entry-luxury coupe and convertible segment. Its primary rivals include the Audi A5/S5 and the Mercedes-Benz C-Class Coupe/Cabriolet.
Performance: The 4-Series is renowned for its engaging driving dynamics, sharp steering, and potent engine options, particularly the M440i's smooth inline-six. The Audi A5/S5 offers a more comfort-oriented ride with competent performance, especially in S5 guise, but often lacks the ultimate driver engagement of the BMW. The Mercedes-Benz C-Class Coupe/Cabriolet prioritizes luxury and a refined ride, with its AMG variants offering strong performance but sometimes at the expense of a harsher ride.
Features: All three offer luxurious interiors with advanced technology. The 2021 4-Series boasts BMW's excellent iDrive system, which is user-friendly and feature-rich. Audi's MMI system is also very capable, while Mercedes-Benz's COMAND system, though visually appealing, can be less intuitive. Driver-assistance technology is generally strong across all competitors, with optional packages offering advanced features.
Reliability: Historically, BMW and Mercedes-Benz have had similar reliability ratings, often slightly below Audi. However, as luxury vehicles with complex systems, maintenance and repair costs can be higher across the board. The 2021 4-Series, being a new generation, is still establishing its long-term reliability record. Early reports suggest it's solid, but the long-term outlook for its sophisticated electronics is something to monitor.
Price: The 4-Series generally positions itself competitively. The 430i often starts at a similar price point to the Audi A5 and Mercedes-Benz C300 Coupe, while the M440i competes more directly with the Audi S5 and Mercedes-AMG C43.
Recommendations:
- Similar Alternatives: If you prioritize a refined and comfortable luxury experience with a stylish design, the Mercedes-Benz C-Class Coupe is a strong contender. For a blend of sportiness and sophistication with excellent AWD capability, the Audi A5/S5 is a great choice.
- Better Alternatives (depending on priorities): For ultimate driving engagement and performance, the Porsche 718 Cayman (though a two-seater sports car) is in a different league but offers unparalleled handling.
