Buying a Used Audi Q5 (2nd Gen FY, 2018–2024): Complete Reliability Guide and What to Watch Out For
The second-generation Audi Q5 (FY), introduced in 2018, refined everything that made the original model so popular. Built on the MLB Evo platform shared with the A4, A6, and Q7, it delivers a perfect balance of comfort, technology, and all-weather performance. With its range of efficient turbocharged engines, Quattro all-wheel drive, and luxurious cabin, the Q5 remains a top choice in the compact luxury SUV class.
But if you’re considering a used Audi Q5, it’s important to understand the real-world reliability and what common problems to look out for. Here’s a detailed guide based on owner experiences and workshop data.
Overview: How Reliable Is the 2nd Gen Audi Q5?
Overall, the 2018–2024 Q5 is a reliable and well-built SUV, especially when maintained according to Audi’s service schedule. Its engines — particularly the 2.0 TFSI and 3.0 TFSI — are more refined and less problem-prone than earlier generations. The dual-clutch S tronic and ZF 8-speed automatics have also proven durable.
However, like any premium European car, the Q5 demands consistent maintenance and quality fluids. Neglect or cheap repairs can quickly lead to costly issues.
Common Problems on the Audi Q5 (FY)
- Oil consumption: Some 2.0 TFSI engines (especially early 2018 builds) may consume oil between changes.
- PCV valve failure: Can cause rough idle or check engine light.
- Carbon buildup: Direct injection leads to deposits on intake valves around 60–80k miles.
- Water pump leaks: Plastic housings can crack or leak coolant.
- Thermostat housing failures: Common on both 2.0 and 3.0 engines.
- Electrical gremlins: MMI glitches, backup camera issues, or power tailgate malfunctions are occasionally reported.
- Transmission hesitation: DSG models may experience slight lag at low speeds if fluid is overdue.
- Suspension wear: Control arm bushings and end links can wear prematurely on rough roads.
Engine Reliability: 2.0 TFSI (EA888 Gen 3)
The 2.0-liter turbocharged four-cylinder (EA888 Gen 3) is the most common engine in the Q5. Producing between 248 and 261 hp, it offers strong performance and good efficiency.
Key points:
- Oil consumption is much improved over earlier versions, though minor use is normal.
- Regular oil changes every 5,000–7,500 miles are recommended to prevent carbon buildup.
- PCV valves can fail, causing rough running or whistling noises.
- Timing chain tensioners are reliable, but always listen for rattles at cold start.
- Carbon cleaning every 60–80k miles restores performance.
Verdict:
A smooth, efficient, and dependable engine when serviced correctly. The EA888 Gen 3 is among Audi’s best-balanced powerplants.
Engine Reliability: 3.0 TFSI V6 (SQ5)
The SQ5 features a 3.0-liter turbocharged V6 (EA839) — a newer, single-turbo design with impressive durability and performance.
Key reliability notes:
- Oil leaks from valve cover gaskets or oil filter housings are possible around 80k miles.
- Water pump and thermostat failures are common maintenance items.
- The turbocharger itself is very reliable when cooled properly.
- Carbon buildup is less severe than in earlier Audi V6s thanks to improved injection design.
- Occasional misfires or vacuum leaks may arise from aging PCV systems.
Verdict:
The EA839 V6 is one of Audi’s most robust modern engines — capable of high mileage and excellent performance with proper maintenance.
Transmission and Drivetrain Reliability
Depending on configuration, the Q5 offers two main transmissions:
- 7-speed S tronic dual-clutch (2.0T models)
- 8-speed ZF automatic (3.0T SQ5)
Known points:
- S tronic units are smooth and reliable but require fluid and filter changes every 40–50k miles.
- Hesitation or jerky shifts often indicate overdue service, not a mechanical failure.
- The ZF 8-speed in the SQ5 is bulletproof with regular fluid changes.
- Quattro AWD systems are extremely reliable; fluid changes every 60k miles are recommended.
Verdict:
Both transmissions are dependable when maintained. Avoid neglected examples with no transmission service records.
Other Components to Watch
- MMI infotainment system: Occasional freezing or black screens, often fixed with software updates.
- Electronic tailgate: May stop working due to latch motor wear or moisture ingress.
- Air conditioning: Weak cooling or bad odor often linked to clogged cabin filters or evaporator leaks.
- Suspension and steering: Control arm bushings and sway bar links wear with age.
- Sunroof drains: Can clog and cause interior water leaks — check for damp carpets.
Maintenance Tips for Longevity
- Use high-quality synthetic oil (VW 502/504 spec) and change every 5,000–7,500 miles.
- Replace transmission fluid and differential oil every 50–60k miles.
- Inspect PCV and water pump every 40k miles.
- Perform intake carbon cleaning every 60–80k miles.
- Keep the MMI software up to date to avoid bugs.
- Wash underbody regularly in winter to protect suspension and subframes.
- Use top-tier fuel to keep injectors clean.
Which Audi Q5 Models to Avoid
- Early 2018 models with reported oil consumption or PCV issues.
- Cars with overdue DSG fluid changes.
- Examples with incomplete maintenance history.
- Vehicles showing signs of coolant leaks or thermostat failures.
- Heavily modified SQ5s without proof of professional tuning and servicing.
