Specs side by side
What owners say
6
Overall
Sentiment is broadly positive, with the Mazda 6 consistently praised for its reliability, longevity, and driving dynamics. Long-term owner reports frequently highlight the vehicle's ability to reach high mileages (e.g., 250,000 miles, 377,000 miles) with minimal major issues when properly maintained. The car is commended for its handsome design, well-regarded interior quality in its class, and a driving experience often described as more engaging than key competitors like the Toyota Camry and Honda Accord.
Best version to buy
Insufficient owner data available to declare a single "best" trim or version across all generations. Feedback is divided by powertrain preference.
Known issues
- ⚠Thin paint / paint chipping and fading: noted on multiple generations, particularly older models. Frequency: recurrent.
- ⚠Rust issues: especially on heat shields and exhaust components, causing rattles; mentioned on pre-2014 models and some later examples. Frequency: recurrent.
- ⚠Steering wheel vibration / shake at highway speeds (55-65 mph / 89-105 km/h): often attributed to tire balance rather than mechanical fault. Frequency: isolated.
Passat
Overall
Sentiment is highly polarized and varies significantly by generation, engine, and market. For certain generations and powertrains, particularly the 2.5L 5-cylinder and pre-2012 TDI models, owner feedback is positive, praising solid build quality, timeless design, comfortable highway cruising, and strong diesel fuel economy (reports of 60+ MPG/3.9 L/100km on motorways). However, a very frequent and dominant criticism centers on below-average long-term reliability and high maintenance costs, especially for turbocharged gasoline (TSI) and certain diesel (TDI) engines.
Best version to buy
For reliability and low cost of ownership, the 2.5L 5-cylinder naturally aspirated gasoline engine (available in North American models circa 2006-2014) is very frequently recommended as "rock solid" and dependable, despite being less powerful and efficient. For fuel efficiency, the 1.9L and 2.0L TDI diesel engines are highly regarded, with the older 1.9L noted for legendary longevity, though the newer 2.0L TDI's DEF/emissions systems are a recurrent source of expensive problems.
Known issues
- ⚠Below-average long-term reliability and high repair costs: very frequent complaints of electrical gremlins, interior trim failures (e.g., door upholstery peeling), and expensive repairs beyond routine maintenance. Frequency: very frequent.
- ⚠Turbocharged gasoline (TSI) engine issues: carbon buildup on intake valves requiring costly cleaning, timing chain and tensioner failures (especially on earlier 2.0T engines), leading to catastrophic engine damage if neglected.
- ⚠Diesel (TDI) emissions system (DEF/AdBlue) failures: particularly on post-2012 models, leading to expensive repairs and reduced reliability despite a robust engine core. Frequency: recurrent.
