What owners say
A7
Overall
Overwhelmingly positive sentiment regarding the driving experience, design, and long-term reliability of the 3.0-liter supercharged V6 gasoline engine (3.0T) and 3.0-liter TDI diesel powertrains. The A7 is consistently praised for its gorgeous, timeless design, exceptional comfort, refined handling with Quattro all-wheel drive, and practical hatchback body style. Owner feedback indicates high satisfaction with the vehicle's performance as a daily driver and long-distance cruiser, with specific acclaim for its quiet cabin, comfortable seats, and high-quality interior build.
Best version to buy
The 2016-2018 model years with the 3.0T supercharged V6 gasoline engine (CREC version, 333 hp) are most frequently recommended. This iteration is noted for having design revisions that address earlier potential issues like carbon buildup (via dual port and direct injection) and updated chain tensioners.
Known issues
- ⚠Higher maintenance and repair costs compared to mainstream brands. Labor and part costs at dealerships are noted as expensive. Frequency: very frequent.
- ⚠Water pump and PCV (Positive Crankcase Ventilation) valve failure. Common replacement items typically needed between 60,000-100,000 miles (97,000-161,000 km). Frequency: very frequent.
- ⚠Emissions system complexity (TDI models). The Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR) system, EGR, and associated sensors are potential failure points with high replacement costs, especially beyond 100,000 miles…
Panamera
Overall
Sentiment is deeply divided and heavily dependent on model year, powertrain, and ownership expectations. Long-term owners of V8-powered models, particularly the GTS and Turbo variants from the second generation (2017+), frequently praise them as among the best daily drivers they have ever owned, citing a blend of exceptional performance, practicality, safety, and surprising reliability with proper maintenance. However, significant and severe criticism is directed at the E-Hybrid models, especially first-generation examples, which are described as profoundly unreliable with catastrophic electrical failures, frequent breakdowns, and extremely short hybrid battery life (reportedly 3-5 years).
Best version to buy
Second-generation (2017+) V8 models, specifically the GTS and Turbo variants. The GTS is highlighted for its intoxicating engine character and as a sweet spot in the lineup.
Known issues
- ⚠Catastrophic E-Hybrid system failures: including complete electrical system failures, stranding owners, requiring frequent towing, and very short hybrid battery life (3-5 years). Frequency: very frequent for first-generation hybrids.
- ⚠Air suspension failures: compressor and component failures, typically occurring after 50,000-70,000 miles, with repairs costing several thousand dollars. Frequency: very frequent.
- ⚠High maintenance and repair costs: extremely expensive parts (e.g., tyres, brakes), dealer service, and repairs; described as "running a £70,000 car" even when purchased used. Frequency: very frequent.
