BMW 4-Series vs BMW 5-Series

Verdict: BMW 4-Series vs BMW 5-Series

The BMW 5-Series exhibits an average reliability score of 65/100, with 54 recalls over eight years and a complaint rate of 3.9 per 10,000 sold. In contrast, the BMW 4-Series currently shows a reliability score of 0/100, lacks any recall history, and has no owner complaints recorded, though this may be due to its recent market introduction. The 5-Series has well-documented issues in several areas including airbags, electrical systems, and powertrain, which are absent in the 4-Series. Based on available data, the 4-Series appears more reliable, but its short time on the market warrants caution until more comprehensive data becomes available.

Reliability problem analysis

The BMW 5-Series exhibits a range of issues, with air bags and the electrical system being the most frequently reported, including a notable number of crash-linked complaints—5 and 4 respectively. Other areas of concern include the engine and power train, though these are less frequently reported. In contrast, the BMW 4-Series has yet to generate any complaint data, suggesting either a lack of reported issues or a smaller sample size. The absence of recorded problems in the 4-Series makes the 5-Series' documented safety concerns, particularly those linked to crashes, more pronounced by comparison.

Which one to buy

If you prioritize reliability and a proven track record, the BMW 5-Series is your better choice. With a reliability score of 65/100, it demonstrates a level of dependability, albeit with some concerns. The model has faced 54 recalls, indicating areas that have been addressed, and has 3.9 owner complaints per 10,000 sold. This suggests that while there are issues, they are being managed and are relatively infrequent compared to the number of vehicles sold.

On the other hand, if you are risk-averse and prefer a model with no identified issues or recalls, the BMW 4-Series might appeal to you. Its reliability score of 0/100 reflects a lack of historical data rather than inherent problems, as it has no recalls or owner complaints reported. However, the absence of data makes it a less predictable choice. Consider this if you value a clean slate but are comfortable with the uncertainty that comes with a newer or less-documented model.
