Audi and Mercedes-Benz swap places between them, and the swap reveals more about each brand than the rankings themselves do.Quick AnswerBMW is the most reliable of the three German luxury brands by both J.D. Power's 2025 Initial Quality Study and Consumer Reports' 2026 Brand Report Card. Mercedes-Benz finishes second on J.D. Power and last on Consumer Reports. Audi finishes last on J.D. Power and second on Consumer Reports. The two surveys measure different things, so the right answer depends on how long you plan to keep the car — and that distinction matters more here than with almost any other comparison you'll read.Ranking At A GlanceJ.D. Power asks owners of new cars what has gone wrong after 90 days and reports it as "problems per 100 vehicles", so 196 means 196 owner-reported problems for every 100 BMWs. Lower is better. The industry average in 2025 was 192. Consumer Reports ranks brands by combining reliability, road test scores, owner satisfaction, and safety, with 1st place being best.BrandJ.D. Power 2025 (problems per 100 cars)Consumer Reports 2026 (rank, lower is better)BMW1965thMercedes-Benz21019thAudi26913thFor context: Lexus led the entire J.D. Power study at 166 problems per 100 cars. Premium brands averaged 203. Audi placed last among rank-eligible brands, which is the kind of sentence Audi's marketing team would prefer you skip over.Three Things The Numbers Don't Tell You1. Audi's worst brand score and its best model score come from the same study. The Audi Q3 ranked first in Small Premium SUV in the 2025 J.D. Power IQS, ahead of the Lexus UX and Mercedes-Benz GLA. The plant in Györ where it's built received a Silver Plant Quality Award. Audi as a brand finished at 269 problems per 100 cars, dead last among rank-eligible brands. Both numbers come from the same study.AudiThe brand average is dragged down by tech-dense newer models, particularly the Q4 e-tron, which Consumer Reports identifies as having problems with the climate system, electrical accessories, in-car electronics, and EV battery and charging. The takeaway: don't buy "an Audi". Buy the specific Audi. The gap between best and worst within the brand is wider than the gap between brands.Related: Related Article2. Mercedes-Benz makes cars that age badly.The Mercedes CLE ranked first in Upper Midsize Premium Car in the 2025 IQS. The E-Class ranked second. The GLS ranked third in Large Premium SUV. The same E-Class and GLS placed at the bottom of their respective categories in Consumer Reports' 2026 reliability data. That isn't a contradiction in the data. It's the data telling you something. The J.D. Power study measures problems in the first 90 days. Consumer Reports measures problems over multiple years of ownership. If you lease a Mercedes for three years and hand it back, you'll get one of the better cars in the segment. If you buy and keep it for five or seven years, you're looking at the lowest-ranked European brand in the survey.John Beltz Snyder3. BMW owners are the slowest to bring cars in for safety recalls.BMW carries the lowest weighted-average recall completion rate (49.0%) of any major manufacturer in NHTSA's January 2025 recall completion analysis covering 2018 to 2022. That doesn't mean BMW makes worse cars; the reliability data already shows it doesn't.. It means when BMW does issue a safety recall, owners take longer to act on it than at other brands.AdvertisementAdvertisementIf you’re buying used, this matters more than new: check the VIN against NHTSA's recall database before buying a CPO BMW, and don't assume previous owners did.BMWWarranty Coverage In 2026All three brands offer the same 4-year/50,000-mile New Vehicle Limited Warranty. The differences are in scheduled maintenance, and the picture shifted for model year 2026:BMW Ultimate Care: 3 years / 36,000 miles complimentary scheduled maintenance, plus 4 years of unlimited-mileage roadside assistance. Included with every new BMW.Audi Signature Care: 3 years / 30,000 miles complimentary scheduled maintenance. New for model year 2026, closing the gap that previously favoured BMW.AdvertisementAdvertisementMercedes-Benz: No brand-wide complimentary maintenance for ICE models. Premier Prepaid Maintenance is a paid product available in 2-, 3-, or 4-year packages. EQ electric models get an integrated service package with service included for up to 2 years.For high-voltage batteries, coverage varies by brand and by state of registration. Mercedes plug-in hybrid batteries get 6 years/62,000 miles base coverage, extended to 10 years/150,000 miles for vehicles registered in California, Colorado, Connecticut, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New York, Oregon, Rhode Island, Vermont, Virginia, and Washington. Check the warranty booklet for the specific BMW or Audi electric or hybrid model you are considering, since terms differ by powertrain and state.Related: Related ArticleWhich To BuyIf you...BuyWant the lowest probability of problems, full stopBMWPlan to lease for 2 to 3 years and return the carAny of the three; Mercedes CLE or E-Class are excellent in the first 90 daysPlan to own and keep the car 5+ yearsBMW first; avoid Mercedes E-Class and GLS based on Consumer Reports dataWant a specific Audi (Q3, Q5, A4) and not "Audi the brand"Audi: model-level data is much better than the brand averageAre buying a luxury EV from one of these threeNone of them lead.

In J.D. Power's 2025 Initial Quality Study, BMW reports 196 problems per 100 cars against Mercedes' 210. In Consumer Reports' 2026 Brand Report Card, BMW ranks 5th overall while Mercedes ranks 19th. Both surveys agree.Audi vs BMW: which is more reliable?BMW, by both surveys. BMW finishes at 196 problems per 100 cars in the J.D. Power 2025 IQS; Audi finishes at 269. In Consumer Reports' 2026 ranking, BMW places 5th and Audi places 13th. Audi's specific models, particularly the Q3 and Q5, score much better than the brand average, but on a brand-vs-brand basis, it isn’t close.Why do J.D. Power and Consumer Reports disagree on Audi vs Mercedes?In short, because they’re measuring different things. J.D. Power captures problems in the first 90 days of ownership. Consumer Reports combines multi-year reliability data with road test scores, owner satisfaction, and safety. Mercedes does well early and fades. Audi's brand average is dragged down by newer tech-heavy models, but its established gasoline lineup holds up better over timeSourcesAll data in this article comes from primary sources, fetched directly:AdvertisementAdvertisementJ.D.
