Avoid the 2010-2014 and 2018-2019 Audi A5 model years due to documented reliability issues including excessive oil consumption, timing chain failures, and airbag recalls[1]. The 2011 A5 is the most problematic year, with engines consuming up to one quart of oil every 1,000 miles and experiencing premature timing chain wear that can cause catastrophic engine damage[2]. For a reliable used A5, target the 2015-2016 models (first generation) or 2020 and newer (second generation)[1].
Audi A5 Generations Overview
The Audi A5 has been produced in two generations since its 2008 US debut. Understanding each generation helps identify which years experienced the most significant problems.
First Generation (B8/B8.5): 2008-2017
The original A5 established the nameplate with its elegant coupe styling and quattro all-wheel drive. The platform received a facelift (B8.5) in 2012 with revised styling and updated engines[3]. However, early models suffered from widespread engine problems, particularly with the 2.0T four-cylinder, which experienced excessive oil consumption and timing chain issues[2].
Second Generation (B9): 2018-Present
The complete redesign introduced a lighter platform, new infotainment system, and revised powertrains. While generally more reliable, early 2018-2019 models experienced electrical issues and build quality concerns typical of first-year production[4].
Audi A5 Years to Avoid
2010-2012: The Most Problematic Years
The 2010-2012 A5 models represent the highest-risk purchases due to multiple serious issues:
| Problem | Impact | Repair Cost |
|---|---|---|
| Excessive oil consumption | Engine damage, oil starvation | $5,000-$10,000+[1] |
| Timing chain tensioner failure | Catastrophic engine damage | $3,000-$7,000[2] |
| Takata airbag recall | Safety hazard | Covered by recall[5] |
| Piston ring defects | Complete engine replacement | $10,000-$15,000[1] |
Oil Consumption Issues: The 2.0T engines in these years burned oil at alarming rates—up to one quart every 600-1,000 miles[2]. This excessive consumption resulted from defective piston rings that failed to properly seal the combustion chamber. When oil levels drop too low, engine internals suffer damage from inadequate lubrication, leading to premature wear and eventual failure.
During a pre-purchase inspection of a 2011 A5 for a client, the compression test revealed significant issues in two cylinders—the direct result of years of oil consumption damage. The repair estimate exceeded $12,000.
Timing Chain Problems: The EA888 engine’s timing chain tensioner was prone to premature failure[2]. When the tensioner fails, the timing chain can skip or break, causing pistons to contact valves and resulting in catastrophic engine damage. This issue triggered class-action lawsuits and settlements against Audi[5].
Takata Airbag Recall: The 2010-2012 models were affected by the widespread Takata airbag recall, where defective inflators could rupture during deployment and send metal fragments into the cabin[5]. NHTSA records show 50 complaints for the 2010 A5 alone, with 29 specifically related to airbag issues[2].
2011: The Worst A5 Year
The 2011 A5 earned distinction as the single worst model year with the highest complaint volume and most severe issues[1]:
- Oil consumption rates: 1.08 quarts per 1,000 miles average[1]
- Drivetrain issues: Unsettling wheel rubbing during morning starts, suggesting bearing or transmission problems[2]
- Airbag malfunctions: Deployment failures in crash situations[2]
The combination of these issues makes the 2011 A5 a vehicle to strictly avoid regardless of price or condition.
2013-2014: Post-Facelift Problems
While the B8.5 facelift addressed some issues, the 2013-2014 models still experienced problems[5]:
- Turbocharger issues: Shaft play and oil leakage requiring replacement[5]
- Continued timing chain concerns: Though improved, not fully resolved[6]
- Settlement-related repairs: Many vehicles required warranty work under the Rieger oil consumption settlement[5]
These years are less problematic than 2010-2012 but still present elevated risk compared to later models.
2018-2019: Early Second Generation Issues
The redesigned 2018 A5 introduced new problems typical of first-year production[4]:
| Issue | Description |
|---|---|
| Electronic trunk malfunctions | Trunk failing to stop when encountering resistance, causing injuries[3] |
| Rapid tire wear | Tires becoming unsafe at 13,000 miles[3] |
| Infotainment glitches | MMI screen freezing, phone connectivity issues[7] |
| Electrical system failures | Module failures causing SOS alarms while driving[4] |
Sun visor breakage was reported while driving, creating safety hazards[3]. Additionally, some owners experienced backup camera malfunctions where cameras randomly switched to graphic mode[4].
Despite Audi issuing Technical Service Bulletins for some issues, warranty extensions or recalls were not offered for many problems[3].
Common Problems Across All A5 Years
Certain issues affect multiple A5 generations, regardless of model year[8]:
Transmission Issues
The Multitronic CVT gearbox (2007-2016) has earned a reputation for problems including[8]:
- Transmission failure
- Shuddering and jerking during acceleration
- Overheating during demanding driving or towing
- Complete loss of power or mobility
The S-Tronic dual-clutch transmission in later models performs poorly at low speeds, causing hesitation and rough shifts in city driving[8].
Infotainment System Problems
The MMI system has been problematic across generations[7]:
- Screen going blank or freezing
- System failing to power on or off
- CD/DVD recognition failures
- Phone Bluetooth connectivity issues
Audi software updates can resolve some infotainment issues, so verifying that service records show the latest updates is important when purchasing.
Coolant Pump Failures
Premature coolant pump failure has been reported across multiple model years, leading to engine overheating if not addressed promptly[7]. This isn’t confined to specific years but warrants inspection during pre-purchase evaluation.
