The BMW 4 Series, since its inception, has positioned itself as a symbol of driving pleasure and engineering excellence. Combining the best aspects of German automotive precision and luxury, it represents an attractive choice for enthusiasts and everyday drivers alike. But when investing in a high-end vehicle like the 4 Series, one pressing question often looms large: Are BMW 4 Series reliable?
This article delves deep into the reliability of the BMW 4 Series, focusing on both objective data and anecdotal experiences from drivers. We will cover various aspects, including build quality, long-term performance, common issues, and maintenance costs, to paint a complete picture of whether the 4 Series can be trusted as a long-term investment.
Introduction to the BMW 4 Series
The BMW 4 Series was introduced in 2013, a spin-off from the iconic 3 Series. It brought with it a more athletic stance, sophisticated styling, and a more luxurious cabin. Available as a coupe, convertible, and later as a four-door Gran Coupe, the 4 Series offers something for nearly every type of driver.
The lineup is powered by a range of engines, from efficient four-cylinders to high-performance inline-sixes. BMW also made M Performance versions available, like the M440i and M4, adding even more excitement to the mix. The allure of the 4 Series lies in its blend of sportiness, luxury, and advanced technology. But how does it hold up in terms of reliability?
Breaking Down Reliability: What It Means in the Automotive World
Before diving into the specifics of the BMW 4 Series, it’s important to understand what “reliability” means in automotive terms. Reliability can be defined as the car’s ability to perform consistently without experiencing significant mechanical or electrical issues. A reliable car requires fewer repairs, has lower maintenance costs over time, and maintains its performance across several years of ownership.
Factors that determine a vehicle’s reliability include:
Engine durability: How long can the engine function without experiencing significant issues?
Transmission robustness: Is the transmission capable of smooth shifts over many miles?
Electrical system: Are the car’s electronic components (infotainment, sensors, etc.) prone to failure?
Build quality: Does the car suffer from excessive wear and tear, or do components break prematurely?
In the luxury segment, where BMW sits, owners typically expect more from their vehicles. High standards of reliability are essential, especially given the premium price tag.
BMW’s Reputation for Reliability: A Mixed History
Historically, BMW has enjoyed a strong reputation for performance, luxury, and driving dynamics. However, when it comes to reliability, the brand has experienced a somewhat mixed history. While older models like the E30 and E46 3 Series earned a reputation for bulletproof engineering, more recent models have faced criticism for increasing complexity and electronic issues.
The 4 Series, being a more modern offering, inherits some of these concerns. Like many modern luxury cars, BMWs have become more dependent on advanced electronics and turbos, which introduce new points of failure. However, when compared to competitors like Mercedes-Benz and Audi, BMW generally fares better in reliability surveys.
BMW 4 Series Reliability: What the Data Says
Reliability ratings for cars are often compiled through consumer feedback, third-party surveys, and long-term tests. Let’s explore how the BMW 4 Series has performed across several key metrics.
J.D. Power Ratings
J.D. Power provides one of the most trusted and comprehensive vehicle reliability studies. They assess cars based on problems experienced per 100 vehicles (PP100). A lower score indicates better reliability.
For the 4 Series, the J.D. Power ratings have typically been average to above average in terms of reliability. Models from recent years have scored around the industry average in terms of dependability. This puts the 4 Series in a respectable position, though not class-leading.
Consumer Reports
Consumer Reports is another key source for assessing vehicle reliability. They base their ratings on extensive owner surveys and feedback.
For the BMW 4 Series, Consumer Reports generally assigns a predicted reliability score of 3 out of 5, which again is in the middle of the pack. Owners frequently cite issues related to the infotainment system and electrical components, but the overall mechanical reliability—particularly the engine and transmission—has been solid.
Warranty and Repair Costs
BMW offers a standard 4-year/50,000-mile warranty, which provides some peace of mind for owners. However, once out of warranty, the cost of repairs can be steep. BMW parts and labor are known to be expensive, especially compared to non-luxury brands.
Reports indicate that repair costs for the 4 Series are higher than the average vehicle. Owners should be prepared for maintenance bills that reflect the car’s luxury status. Common repairs, like replacing brakes, dealing with electronics, or fixing oil leaks, can add up quickly.
Common Issues in the BMW 4 Series
No car is perfect, and the BMW 4 Series is no exception. Over the years, several common issues have been reported by owners and mechanics. Here’s a breakdown of some of the more frequent problems associated with the 4 Series:
Electrical Problems
One of the most commonly reported issues in the BMW 4 Series is related to its electrical system. This includes malfunctions with the iDrive infotainment system, erratic behavior of the navigation system, and problems with the car’s sensors and electronics.
Many drivers have expressed frustration with screen freezing or failure of the rearview camera. While these issues might not leave you stranded, they can be bothersome and require trips to the dealership for software updates or repairs.
Turbocharger and Fuel System Problems
The turbocharged engines, particularly the B48 2.0-liter inline-four and B58 3.0-liter inline-six, are praised for their performance. However, turbocharged engines introduce a level of complexity, and some owners have reported issues with the turbocharger and fuel systems, particularly in older models or cars with higher mileage.
Symptoms include loss of power, rough idling, or even a check engine light related to the turbo wastegate or fuel injectors.
Oil Leaks and Gasket Failures
BMW has a history of oil leaks, and the 4 Series is no different. Valve cover gaskets, oil pan gaskets, and timing chain cover gaskets are all known to fail prematurely, leading to oil leaks. This issue is common across many BMW models, not just the 4 Series.
Owners may notice oil spots under the car, a burning smell, or even low oil levels, prompting the need for more frequent top-ups.
Suspension and Steering Issues
While the 4 Series offers sharp handling, it’s not immune to suspension problems. Some drivers have reported issues with the front suspension components, particularly worn-out bushings and control arms. These can lead to uneven tire wear, noisy suspension, or a rougher ride.
BMW’s steering systems have also come under scrutiny, with some drivers noting issues with steering feel and occasional power steering malfunctions.
Strengths of the BMW 4 Series: Why People Still Love It
Despite these issues, the BMW 4 Series continues to enjoy a loyal following. Here’s why:
