Used Audi Q5 2nd Gen (2018–2024): Buyer's Guide

The 2018 Audi Q5 logged 193 NHTSA complaints. The 2019 logged 45. Same MLB Evo platform. Same 2.0T engine. Same body. The difference is Audi's first-year bugs plus one significant recall. That gap tells you exactly where the B9 generation got sorted, and where it didn't.

This is not a guide about whether the Q5 is a good car. It is. This is a guide about which specific years, powertrains, and configurations to buy — and what will happen to your wallet after the warranty runs out. The B9 generation runs from 2018 through 2024. It has three meaningfully different powertrain families, a major facelift in 2021, two fire-risk recalls, and one class-action water pump settlement. All of that matters before you spend $18,000 to $38,000 on one.

This Generation at a Glance

The second-generation Q5 (internal code 80A, platform MLB Evo) launched as a 2018 model year and replaced the 8R platform that ran from 2009 to 2017. Key platform gains: a lighter all-aluminum construction, a new quattro Ultra on-demand AWD system, and a standard 7-speed S-tronic dual-clutch transmission replacing the torque-converter unit from the first gen.

A meaningful mid-cycle facelift arrived for the 2021 model year: new MIB3 infotainment (10.1-inch touchscreen with 10x the processing power of the prior system), 12V mild hybrid system added across the lineup, power bumped from 248 hp to 261 hp on the base engine, a plug-in hybrid (Q5 TFSI e) added to the lineup, and exterior restyling. The 2022 model year added S Line exterior packaging as standard and expanded the PHEV battery from 14.1 kWh to 17.9 kWh gross.

Powertrain and Trim Breakdown

Q5 45 TFSI — 2.0T EA888 (2018–2024)

The 2.0T is the volume engine. Most used B9 Q5s you'll find carry this motor. It's the Volkswagen Group EA888 Gen 3 or Gen 4, depending on vintage, and it's a capable engine that improves significantly from the first generation. But it has documented failure points that owners encounter with regularity above 60,000 miles.

Water pump. The most common costly repair on the B9 2.0T. The water pump and thermostat sit in an integrated plastic housing. Volkswagen Group acknowledged the failure pattern through a class action settlement that extended water pump warranty coverage to 8 years/80,000 miles and issued TSB 19 23 44 2071515/1. The fix is a replacement of the integrated assembly at around $1,300. Ask for service history. If the car is past 80,000 miles and the water pump hasn't been replaced, factor that into your offer.

PCV valve. The positive crankcase ventilation valve uses a rubber diaphragm that hardens and cracks over time. When it fails, crankcase pressure builds, oil consumption increases, and you may see oil being pushed out of seals and gaskets. The valve itself is a cheap part. Preventive replacement around 70,000 miles is widely recommended on AudiWorld and AudiZine forums. If you're looking at a high-mileage Q5 with no PCV service history, it's worth doing immediately after purchase.

Valve cover gasket. Oil seepage from the valve cover gasket is a common complaint above 60,000 miles. An independent Audi shop typically charges $300–$600. Dealer quotes of $1,500–$2,000 are not unusual. When inspecting a used Q5, look and smell for oil residue around the top of the engine. It's not catastrophic but it's a negotiating point.

DSG / S-tronic jerkiness. The 7-speed dual-clutch transmission shows a characteristic low-speed jerk during 2nd-to-1st downshifts, particularly when coming to a stop. Forum threads going back to 2018 document this across multiple owner-reported cases on MyAudiQ5.com. Audi has issued software updates that reduce but don't eliminate this behavior. Test drive at parking lot speeds specifically. A car that lurches hard into first gear is not "normal."

Oil consumption. The EA888 family has a history of oil consumption via carbon-fouled piston rings. The B9 generation is better than the 8R, but it's not immune. Check oil level before a test drive — and again after. Owners on AudiWorld report consumption of 1 quart per 2,000–3,000 miles on high-mileage examples.

MMI infotainment (2018–2020 only). The older MIB2 system in pre-facelift Q5s is prone to freezing and random reboots. TSBs 2030465 and 2055591 address software issues. The 2021+ MIB3 system is meaningfully better. If you're considering a 2018–2020 car with MMI issues, verify current software version at an Audi dealer before purchasing.

What owners consistently love: The 2.0T Q5 drives well for a family SUV, delivers genuine all-weather confidence with quattro, and the interior quality is a clear step above most Japanese or domestic alternatives in this price range. Forum consensus is that a well-maintained 2.0T Q5 easily reaches 150,000+ miles.

SQ5 — 3.0T EA839 Turbo V6 (2018–2024)

The SQ5 uses the EA839 3.0T turbocharged V6 (not the supercharged 3.0T from the first-gen SQ5). It's genuinely fast: 349 hp, 0–60 in under 5 seconds, and a soundtrack that justifies the premium over the base car. It also carries more concentrated mechanical risk.

Water pump — critical. The EA839's factory water pump is widely documented as a failure waiting to happen. The design uses internal vacuum pressure to operate a slide valve that controls coolant flow through the impeller. When the vacuum system fails, the pump stops moving coolant. One Audi performance shop documented over 14 EA839 engine failures at a single dealership in a 6-week period, all on stock vehicles. The failure rate appears to be well below 5% of EA839 engines — but when it fails, it can cause rapid overheating. Ask specifically whether the water pump has been replaced. An aftermarket billet aluminum replacement pump is the permanent fix; factory units should be considered time-limited parts. Expect $1,500–$2,500 for a proper replacement at a specialist shop.

Piston failures — rare but serious. A documented (though sub-5%) failure on the EA839 involves piston skirt wear from piston rocking under load, leading to piston structure fatigue. Some affected engines have returned with metal shavings in the oil within 3–4 weeks of service. If you're buying an SQ5, ask for the last oil change records and request an oil analysis if the car has over 60,000 miles. Metal in the oil is a walk-away.

Cylinder 6 misfires. Multiple owner reports on AudiWorld document misfires specific to cylinder 6 on the EA839. Some cases involved metal shavings in the oil before the misfire appeared. This is distinct from the piston issue above but may be related to the same root cause.

PCV system. Like the 2.0T, the SQ5's EA839 has PCV system issues. Forum threads on VWVortex and AudiWorld document PCV failures leading to oil consumption and crankcase pressure. Not as acute as the water pump issue but worth monitoring.

What owners love: SQ5 owners are largely enthusiastic about the powertrain when it works. The car is genuinely quick, handles well for its class, and the V6 is smooth and distinctive. The 8-speed Tiptronic also feels more refined than the 7-speed dual-clutch in the base car. Most SQ5s run trouble-free; the water pump is the key variable.

Q5 TFSI e — Plug-In Hybrid (2021–2024)

The PHEV Q5 produces 362 hp combined from the 2.0T plus an electric motor, and in 2022 got a battery capacity upgrade to 17.9 kWh gross. Electric range was officially rated at 26–35 miles depending on conditions. The PHEV is the only Q5 variant with standard full-time quattro (not quattro Ultra) and the only one with a high-voltage battery.

Battery fire recall — mandatory check before purchase. NHTSA recall 25V080000 (superseding 24V898000) affects 2022–2023 Q5 PHEV models built between August 10, 2021, and December 10, 2022. The Samsung SDI high-voltage battery cells can overheat and cause a thermal event — a fire. Audi recalled 4,616 PHEV units in the US. Owners with detected faults were told not to charge the vehicle. Before buying any Q5 TFSI e, run the VIN through the recall checker to confirm this recall was completed.

Battery range degradation. Some PHEV owners report electric range dropping from 30+ miles to under 15 miles within 2.5–3 years of ownership. The battery warranty covers degradation beyond 30% for 8 years/100,000 miles — but proving degradation at a dealer can take time. Ask the seller to demonstrate electric range in real-world conditions before signing anything.

Charging system recall. NHTSA recall 23V842000 affects Q5 PHEV models with the included 220V/240V Level 2 charging cable. An overheated outlet or cable can cause a fire. Remedy is a replacement cable with a temperature sensor. Also check whether this recall is complete.

Trim-Specific Notes

The B9 Q5 came in three trim levels throughout most of its run: Premium, Premium Plus, and Prestige. The SQ5 started in Premium and went up to Prestige.

Premium is the value buy. It includes leather, push-button start, Apple CarPlay/Android Auto, and 18-inch wheels. Good pick for buyers who don't care about panoramic sunroofs or LED headlights.

Premium Plus is the sweet spot. Adds the panoramic sunroof, full LED headlights, front/rear parking sensors, heated front seats with memory, blind spot monitoring, and 19-inch wheels. For daily use, the Premium Plus covers essentially everything you actually use. The 2019 model year added rear USB charging ports and wireless phone charging to this trim.

Prestige adds the head-up display, Bang & Olufsen audio, 360-degree bird's-eye camera, virtual cockpit digital gauge cluster, and adaptive cruise with traffic jam assist. Worth seeking if you find one at a price that makes sense — but don't pay a large premium over a well-equipped Premium Plus just for the B&O system.

Optional equipment to assess carefully:

The available adaptive air suspension (offered on some SQ5 Sport packages) raises the ride quality meaningfully but brings failure risk. At 80,000+ miles, air strut failures can run $2,000–$4,000 to correct. If you see an SQ5 with air suspension, confirm the system shows no fault codes and holds pressure. The standard coil/passive suspension is more reliable and still rides well.

The black optic appearance package (2022+) adds 20-inch wheels. Great aesthetics, but 20-inch tires wear faster and cost more per set. Budget accordingly.

Which Model Years to Target

2019 is the statistical sweet spot. Zero recalls. Forty-five complaints versus 193 for 2018. First-year problems resolved. Software matured. Pre-facelift means the MMI system is the older touchpad type (not the superior 2021 touchscreen), but the mechanical package is well-sorted.

2021 is the best buy for technology. The MIB3 infotainment is a generational improvement. MHEV adds fuel economy without the complexity of the full PHEV. The mild hybrid belt does require attention at 60,000 miles. Verify the gateway module recall (21V947) was completed — this covers 2021–2022 models and a subset of earlier years.

2022–2024 require recall verification. The cylinder head cover screw recall (25V294000) covers approximately 89,000 vehicles. Factory screws were improperly torqued, and over time they loosen, creating an oil leak that can drip onto hot engine components. Audi documented 11 thermal events. The repair is free — but only if it's been done. Never buy a 2022–2024 Q5 without confirming this recall is complete.

Skip 2018. The 193 NHTSA complaints speak for themselves. The airbag/seatbelt recall, first-year MMI instability, and elevated suspension and electrical complaint rates make it the weakest year of the generation.

Pre-Purchase Inspection Checklist

For any Q5 45 TFSI (2.0T):

• Start the car cold. Any coolant smell or steam from the engine bay signals a water pump failure in progress. Check the coolant reservoir level before driving.
• Check the oil level with the car at operating temperature. The EA888 consuming oil between service intervals is a documented pattern on higher-mileage examples.
• After the test drive, let the engine idle and smell around the valve cover area. Oil residue or a burning smell indicates a seeping valve cover gasket.
• Test the S-tronic at parking lot speeds. Approach a stop and feel for a hard jerk as the transmission drops to first. Minor smoothness is normal; a pronounced lurch is a software or clutch pack issue.
• On 2018–2020 cars: launch the MMI, open maps, play audio, connect a phone. Leave it running for 10 minutes. A system that blacks out or reboots has a known TSB issue.
• Ask for water pump replacement records. If the car is past 80,000 miles and the pump hasn't been replaced, you're buying a near-term repair.

For SQ5 (3.0T EA839):

• Check the coolant level before starting. A low reservoir on a warm car can mean a slow water pump leak already in progress.
• After the test drive, check for any overheating history in the infotainment trip log.
• Request the most recent oil change receipt. A shop that drained the oil recently should have noted any metallic contamination. If you can pull a sample for oil analysis, do it.
• Start cold and listen for timing chain rattle — a rattling sound that follows RPM and may fade as the engine warms. If it's still there at operating temperature, the chain tensioner is worn.
• Check for cylinder 6 misfire codes. An OBD2 reader with live data can pull stored fault codes before clearing them.

For Q5 TFSI e (PHEV):

• Run the VIN at recall-lookup before anything else. Confirm recalls 25V080000 (battery overheating) and 23V842000 (charging cable) are both completed.
• Test electric-only range on a full charge under real driving conditions. Below 15 miles suggests significant battery degradation. The spec is 25–35 miles.
• Check whether the 12V auxiliary battery has been recently replaced (it powers systems when the high-voltage battery isn't engaged and tends to fail more often on PHEVs).

All variants:

• Run VIN for recall 21V947 (gateway module) on any 2018–2022 Q5 or SQ5. The fix takes about an hour and is free. Unrepaired vehicles may enter engine limp mode unexpectedly.
• Run VIN for recall 25V294000 on any 2022–2024 Q5. The cylinder head cover screw fix is free and takes under 30 minutes. An unrepaired car has documented fire potential.
• Check the rear subframe and lower control arm ball joints for corrosion during any lift inspection. Snow-belt cars are more vulnerable.
• On cars with optional air suspension: connect to the Audi MMI diagnostics menu and check for active suspension fault codes. Ask the suspension to raise and lower. If it takes more than 20 seconds to respond, the compressor is struggling.

Running Costs

Audi dealer oil changes for the Q5 run $150–$220 per service. An independent Audi specialist typically charges $90–$130. The 10-year ownership cost for a Q5 runs approximately $12,919 in maintenance alone per CarEdge data — roughly $1,300 per year. Budget accordingly versus a comparable Japanese SUV at roughly half that figure.

Premium 93-octane fuel is required on all Q5 powertrains. Budget $300–$400 per year in additional fuel cost versus regular-grade vehicles.

Frequently Asked Questions

Is the 2nd gen Audi Q5 2.0T reliable? The 2.0T EA888 is a solid engine when maintained properly. Water pump replacement is the key high-mileage item (extended warranty to 8 yr/80K via class action). Well-maintained 2.0T Q5s regularly reach 150,000 miles. The 2019 model year has the best complaint-to-recall ratio of the generation — zero recalls and 45 NHTSA complaints, versus 193 for the 2018.

What year Q5 should I avoid? The 2018 is the weakest year of the B9 generation. First-year production issues generated 193 NHTSA complaints, roughly four times more than the 2019. The airbag/seatbelt recall also affects 2018 vehicles. The 2022–2024 cars are fine once the cylinder head cover screw recall (25V294000) is completed, but buying one without verifying that recall is a significant risk.

Is the SQ5 reliable compared to the Q5? The SQ5's EA839 3.0T carries more mechanical risk than the Q5's 2.0T, specifically around the water pump. The 2.0T Q5's water pump failure is common; the EA839's water pump failure is more consequential. Both are addressed with known fixes. A well-maintained SQ5 is a great vehicle — but budget for a water pump replacement at or before 80,000 miles.

Is the Audi Q5 PHEV worth buying used? The Q5 TFSI e offers genuinely useful electric range (25–35 miles on 2022+ cars) and strong performance at 362 hp. The fire recall on Samsung SDI battery cells covering 2022–2023 models must be verified completed before purchase. Post-recall, the PHEV is a compelling daily driver with very low fuel costs for short-range driving.

How many miles will a 2nd gen Q5 last? With proper maintenance and oil changes at the 10,000-mile interval, the EA888-powered Q5 regularly reaches 150,000–200,000 miles. The big variable is whether the water pump and PCV system are addressed proactively. Deferred maintenance on these items cascades into larger repairs. The SQ5 follows the same pattern — the water pump is the key risk variable.

Bottom Line

The 2019 Q5 45 TFSI is the cleanest buy in the B9 generation — zero recalls, the lowest complaint count, and a mechanically sorted 2.0T that's past first-year quirks. For more technology, the 2021 with MIB3 infotainment is worth the premium if you can find one with the gateway module recall completed. Avoid the 2018.

On the SQ5, the 2019 and 2020 are the sweet spots — the EA839's water pump is a when-not-if replacement, but those years are clear of the larger recall stack that arrives from 2021 onward. For any 2022–2024 Q5 or SQ5, the cylinder head cover screw recall (25V294000) must be verified completed before you buy.
