What owners say
Our take, from owner reports
Sentiment is generally positive among long-term owners, particularly for the D5 generation (2018+), which is praised for its exceptional ride comfort, quiet cabin, advanced technology, and strong value proposition on the used market.
7 problems reported (2 very frequent, 3 recurrent, 2 isolated) · medium confidence
Problems owners report
- Very frequentHigh maintenance and repair costs
Very expensive parts (e.g., air struts ~$2,200 each, headlights ~$3,000) and labor, leading to high annual ownership costs.
- Very frequentRapid depreciation
Significant loss in value, especially in the first few years, though this makes the car a strong used value.
- RecurrentMild Hybrid System (Belt Starter Generator/BSG) failures
A known issue on D5 (2018+) models with the 48V system, potentially leading to expensive repairs; subject to a technical service campaign (27BQ).
+ 4 more issuesShow fewer
- RecurrentElectronic gremlins
Concerns over long-term reliability of complex infotainment, driver aids, and other electronic systems; some isolated reports of issues requiring multiple resets.
- RecurrentAir suspension failures
A noted point of potential failure and high repair cost, particularly on higher-mileage examples of all generations.
- IsolatedAdaptive Cruise Control (ACC) sensor failures
Isolated reports on early D5 models where rain or fog caused malfunctions, sometimes requiring replacement.
- IsolatedRocker arm issues in EA839 3.0T engine
Mentioned as a potential but less common issue, primarily noted in tuned engines and earlier (pre-2019) model years.
The version owners recommend
For the D5 generation (2018+), a well-optioned example is highly recommended. Key desired options include the Executive Package (22-way seats with ventilation/massage, head-up display), Driver Assistance Package (adaptive cruise with traffic jam assist), dual-pane acoustic glass, the premium lighting package (HD Matrix LED, OLED taillights), and the Bowers & Wilkins audio system. The 3.0T V6 (55 TFSI) is the common powertrain, but some owners express a preference for the V8 (60 TFSI) or wish for the V6 PHEV variant not sold in the U.S. For the D4 generation (2011-2017), the 4.2L TDI diesel is highlighted for its immense torque (627 lb-ft), strong acceleration (0-60 mph/0-97 km/h in ~4.7 seconds), and impressive fuel economy (up to 38 mpg).
Competitors to consider
Owners compare it most often with the Mercedes-Benz S-Class (specifically W222 and W223 generations), BMW 7 Series (G11/12 and G70 generations), Lexus LS, Porsche Panamera and Genesis G90.

Overall sentiment
Sentiment is generally positive among long-term owners, particularly for the D5 generation (2018+), which is praised for its exceptional ride comfort, quiet cabin, advanced technology, and strong value proposition on the used market. The D5 is frequently described as a "hovercraft" for its sublime, non-floating air suspension and is noted for being significantly lighter than its rivals due to its aluminum construction, contributing to better handling and fuel economy. Owner satisfaction is often tied to purchasing the vehicle as a lightly used or CPO example at a steep discount from MSRP, where its blend of luxury, technology, and driving dynamics presents a compelling alternative to the Mercedes S-Class and BMW 7 Series. Criticisms are primarily focused on high maintenance and repair costs, concerns over the reliability of complex electronic systems and specific components like the mild hybrid system, and the car's significant depreciation. For older generations (D3, D4), feedback centers on the potential for expensive repairs, particularly with air suspension and aging electronics, though well-maintained examples with thorough service records are still appreciated.
Positioning vs competitors
Positioned as a more driver-oriented and technologically advanced alternative to the Mercedes S-Class and BMW 7 Series, with a more understated design. The D5 A8 is consistently noted for its superior ride-handling balance: being more composed and less floaty than the S-Class while offering better technology (e.g., Level 3 autonomous driving capability at launch) than the contemporary W222 S-Class and G12 7 Series. It is considered the best value proposition among the German trio on the used market, often selling for significantly less than comparable-age rivals, which attracts buyers but also reflects its lower brand cachet and sales volume. It is viewed as less flashy and more rare on the road than the ubiquitous S-Class. Against the Lexus LS, the A8 is seen as more engaging to drive but potentially less reliable long-term.
Recommended configurations
A lightly used or CPO D5 A8 L with the aforementioned option packages. A pre-purchase inspection (PPI) from a knowledgeable independent mechanic is considered essential. Purchasing with a remaining factory or extended warranty (e.g., Audi After Care Platinum) is strongly advised to mitigate repair costs. For winter climates, downsizing from the large optional wheels (e.g., 21") to 19" or 20" wheels with winter tires is recommended for significantly better snow and ice traction.
General recommendations
Highly recommended for buyers seeking a full-size luxury sedan with a superb blend of comfort, technology, and engaging driving dynamics who are willing to purchase used at a steep discount. Suitable for owners who value a quiet, comfortable cabin for long commutes or traffic. Not recommended for buyers unwilling to budget for high maintenance costs or those who prioritize brand prestige and high resale value. Essential steps before purchase: obtain full service records, conduct a thorough PPI focusing on electronics and suspension, verify all recalls/TSBs (especially campaign 27BQ for the Belt Starter Generator on D5 models) have been addressed, and budget a significant annual reserve ($2,000-$5,000+) for maintenance and repairs.
Remarks
The D5 generation's value is a dominant theme; owners report purchasing nearly-new examples for dramatic discounts (e.g., a $106k MSRP car bought CPO for $62k), which fundamentally shapes positive ownership sentiment. The car's aluminum Audi Space Frame is a key differentiator, reducing weight compared to rivals and contributing to its praised driving dynamics. Owner feedback suggests a notable improvement in reliability for post-2022 models following a mid-cycle refresh. The future of the A8 model line is noted as uncertain, with declining sedan sales and no confirmed successor platform, which may impact long-term support and residual values. Analysis based on owner discussions spanning multiple generations, with the most detailed feedback focusing on the D4 and D5.
