Inside, the 2014 A4 carried Audi’s tradition of class-leading interiors. The cabin blended understated elegance with exceptional build quality, featuring standard leather upholstery and premium materials throughout. Its design favored simplicity and refinement over flashiness, giving it a timeless appeal.
Passenger space was generous for the segment, with rear outboard seats offering adult-friendly legroom and headroom, while the 12.4-cubic-foot trunk was average for the class.
Audi’s MMI infotainment system provided centralized control over navigation, audio, and connectivity features, though some functions required delving into deeper menus.
Compared to BMW’s iDrive or Mercedes’ COMAND, MMI was slightly less intuitive, especially in non-navigation-equipped models where the controller was placed on the dash. Nonetheless, the A4’s cabin quality, comfort, and practicality made it one of the most attractive interiors in the small luxury sedan category.
4. 2015 Audi A4
The 2015 Audi A4 continued the upward trajectory of dependability established in the previous model year, earning a strong 4 out of 5 rating for reliability from Consumer Reports. This marked a dramatic improvement from earlier B8-generation models, which had been plagued with complaints.
By 2015, reports of engine issues had dwindled to a mere handful, while other categories tracked by the NHTSA showed only single-digit complaint numbers. Although largely unchanged from the 2014 version, the A4 remained a formidable contender in the entry-level luxury sedan market.
With its blend of confident performance, a premium interior, and excellent safety ratings, it solidified itself as a top choice for buyers seeking a well-rounded luxury car.

Inside, the 2015 Audi A4 upheld the brand’s reputation for cabin excellence. The interior exuded understated sophistication, with clean lines, premium materials, and standard leather upholstery setting it apart from BMW and Mercedes rivals that used synthetic leather.
Space was generous for the segment, with front seats offering excellent comfort and rear outboard seats providing adequate room for adults. The 12.4-cubic-foot trunk was average, but practical enough for everyday use. Audi’s MMI infotainment system provided centralized control of navigation, audio, and connectivity functions.
Though effective, it was slightly less intuitive than BMW’s iDrive or Mercedes’ COMAND, particularly in models without navigation, where the MMI controller was located on the dash instead of the center console.
Even so, the A4’s combination of craftsmanship, practicality, and premium ambiance ensured it remained one of the most desirable small luxury sedans in 2015.
5. 2016 Audi A4
The 2016 Audi A4 marked the final year of the B8 generation and did so on a high note. Consumer Reports awarded it a 4 out of 5 for reliability, while CarComplaints recorded just one engine-related issue, confirming that the lingering problems of earlier years had been resolved.
Audi trimmed the lineup for 2016, discontinuing the Prestige trim and redistributing equipment among the remaining Premium and Premium Plus models. Base trims now included heated mirrors and a sportier three-spoke steering wheel, although adaptive cruise control was no longer offered.
Despite being one of the oldest models in the compact luxury sedan segment at the time, the A4 maintained a strong reputation for comfort, refinement, and balanced driving dynamics, proving that a well-honed design can age gracefully.
Under the hood, every 2016 A4 featured the familiar 2.0-liter turbocharged four-cylinder engine, producing 220 horsepower and 258 lb-ft of torque. Buyers could choose between front-wheel drive with a CVT or Quattro all-wheel drive with either a six-speed manual or an eight-speed automatic transmission.
Performance was competitive, with Audi estimating 0–60 mph in 6.6 seconds with the CVT, 6.4 seconds with the manual, and 6.2 seconds with the automatic. Fuel economy matched rivals closely, returning up to 27 mpg combined with the CVT, 26 mpg with the manual, and 25 mpg with the automatic.
While competitors like BMW and Mercedes offered slightly stronger powertrains and better efficiency, the A4’s combination of responsive acceleration and sure-footed Quattro grip made it an appealing choice for buyers who valued both confidence and capability.
On the road, the 2016 A4 delivered the composed and polished driving experience that had long been a hallmark of the model. The standard suspension setup balanced comfort and control, providing a smooth ride over rough roads without sacrificing stability in corners.
For drivers seeking sharper handling, the Sport package added a lowered suspension and stiffer tuning, though this came at the expense of ride comfort, particularly when paired with the available 19-inch wheels.
Braking performance was excellent, with tests showing the A4 could stop from 60 mph in just 108 feet when equipped with summer tires.
Safety credentials were strong as well, with a perfect five-star rating from the NHTSA and “Good” ratings in most IIHS crash tests, though like earlier models, it struggled in the small-overlap frontal-offset test, earning a “Poor” score.
Inside, the 2016 Audi A4 demonstrated why the brand’s cabins were often considered benchmarks in the luxury segment. While the design dated back to the late 2000s, its restrained layout and premium materials helped it remain stylish and sophisticated.
Standard leather upholstery set it apart from rivals that relied on vinyl, and Audi’s signature red-lit gauges reinforced the premium feel. The cabin was spacious for a compact luxury sedan, with ample front-seat comfort and sufficient rear-seat head- and legroom for adults.
Cargo capacity was average, with 12.4 cubic feet of trunk space. Audi’s MMI infotainment system, controlled via a rotary dial and buttons, remained effective though slightly less intuitive than BMW’s iDrive.
Higher trims benefited from a console-mounted controller and upgraded screen, enhancing usability. Altogether, the 2016 A4 closed out its generation as a mature, well-rounded, and highly reliable option in the luxury sedan market.

5 Audi A4 Years To Avoid
1. 2008 Audi A4: Early Warning Signs
The 2008 Audi A4 is often remembered for introducing recurring reliability problems that would plague the model for several years. The most notable issue was with oil consumption and monitoring. Owners reported oil leaks, incorrect recognition of oil levels between changes, and overconsumption at relatively low mileage.
Beyond this, climate control issues began appearing after a few years, particularly with the air conditioning system, which struggled to maintain performance.
Despite these setbacks, when properly maintained, the A4 still offered a comfortable and composed drive, demonstrating Audi’s strength in design and ride quality. However, the reliability concerns overshadowed its positives.
Safety recalls also created concern for 2008 buyers, particularly surrounding airbags. There were five separate recalls related to corrosion, delayed deployment, or even explosions upon deployment, mostly affecting the driver’s side.
These safety defects reflected a deeper issue with long-term dependability. While the A4 provided the refinement expected from a German luxury sedan, the mix of costly oil issues, potential climate system repairs, and critical airbag recalls marked it as a model year for buyers to approach with caution.
2. 2009 Audi A4: A Risky Transition Year
Following in the footsteps of the 2008 model, the 2009 Audi A4 suffered from similar oil issues but also faced an even bigger concern: engine failures. Many owners experienced severe problems with oil consumption that, if ignored, led to engine damage over time.
While some considered the 2009 A4 a decent used luxury sedan thanks to its comfort and features, the reality was that the cost of ownership climbed sharply. Repairs tied to overconsumption and mechanical breakdowns made it one of the more expensive used Audis to maintain, especially as mileage increased.
Fuel economy was another weak point. The 2009 A4 consumed more fuel than many rivals and, when paired with the oil issues, earned a reputation for inefficiency and unreliability. On the safety front, the 2009 model inherited the same five airbag recalls as the 2008 A4.
These ranged from corrosion issues to deployment failures, undermining buyer confidence. In the long term, the 2009 model became one of the least recommended due to its combination of recalls, mechanical breakdowns, and excessive repair costs.
3. 2011 Audi A4: The Worst Model Year
If 2009 was bad, the 2011 Audi A4 was worse in terms of mechanical reliability and cost of repairs. This model year is widely considered the worst of the A4 lineup due to widespread engine-related failures. Owners complained of extreme oil consumption, frequent breakdowns, and poor fuel efficiency.
The most common problem involved costly engine replacements, often averaging more than $5,000. This turned the 2011 A4 into a financial burden for many buyers, with recurring repair expenses stacking up at relatively low mileage.
Interestingly, while 2011 had fewer total complaints than 2009, the severity of its issues elevated its reputation as the least desirable A4 year. While 2009’s problems were frequent, 2011’s were catastrophic, often requiring full engine replacements rather than piecemeal repairs.
Unlike earlier years, 2011 did not face widespread recalls, meaning its biggest problems were not addressed through manufacturer fixes but left to owners to handle. As such, it became a prime example of a model year where Audi’s engineering faltered, leaving drivers with high ownership costs and low confidence in long-term reliability.
4. 2003 Audi A4: A Troubled Second Generation
Stepping back to the second generation, the 2003 Audi A4 stands out as one of the worst-built versions of the sedan. It marked the beginning of a particularly poor stretch for Audi, characterized by inconsistent build quality and frequent breakdowns.
According to the National Highway Traffic Safety Administration (NHTSA), the 2003 model racked up 215 complaints, one of the highest totals in the model’s history. Issues spanned across the fuel system, engine cooling, and speed control, showing that the problems were not isolated but systemic.
In addition to the complaints, four recalls were issued for the 2003 A4, two of which addressed recurring fuel pump failures. This made the car unpredictable and costly to maintain, with reliability suffering even when repairs were performed.
Many of these vehicles began to experience significant wear by just 60,000 miles, well before the expected lifespan of a premium sedan.
Given the volume and range of issues, the 2003 A4 is often cited as a turning point that damaged Audi’s reliability reputation for much of the following decade, until improvements were finally seen with the 2012 redesign.
5. 2017 Audi A4: A Rocky Start to the Fourth Generation
While Audi made major strides in the 2010s, the 2017 A4 marked another problematic launch year. This model introduced the fourth generation of the A4, yet it struggled with reliability despite offering strong performance and driver satisfaction.
Consumer Reports noted a high owner satisfaction score of 4 out of 5, but reliability scores lagged behind with an average of just 37 out of 100. Owners praised the driving experience, but frequent complaints about electrical systems, climate control, leaks, and engine failures kept the 2017 model from ranking among the more dependable A4s.
The issues were visible in complaint records as well. CarComplaints data showed a sharp spike in problems for 2017 compared to the years before and after. Airbag concerns again dominated safety-related reports, making up nearly half of the 31 NHTSA complaints and three of the five recalls issued.
While some enjoyed the refinement and updated features of the 2017 redesign, the reliability concerns made it an undesirable choice for those prioritizing long-term ownership. In hindsight, the 2017 A4 mirrored earlier troubled transition years like 2009, where first-year redesigns proved riskier than later, better-refined versions.
The Audi A4 remains a compelling choice for drivers who want a refined luxury sedan that blends performance, comfort, and style. While the model has had its ups and downs over the years, certain versions have proven to be especially reliable and rewarding, making them smart buys on the used market.
At the same time, some model years are best avoided due to recurring issues that can lead to costly repairs and frustration. For anyone considering a pre-owned A4, doing thorough research and prioritizing maintenance history is essential to ensuring a positive ownership experience.
Ultimately, the best examples of the A4 showcase timeless German engineering, a premium interior, and driving dynamics that continue to impress enthusiasts and everyday drivers alike.
By choosing carefully, buyers can enjoy the luxury and confidence the A4 is known for, while steering clear of the pitfalls that can come with the wrong model year.
