Mercedes Classe E W212 (2009 – 2016)
Reliability score : 8.2/10
The Mercedes-Benz E-Class generation W212 (saloon), S212 (estate), C207 (coupe) and A207 (cabriolet) marks a major turning point for the star brand. After a W211 generation marred by electronic issues in its early days (notably the SBC braking system), the W212 was designed with a drastic specification focused on reliability and robustness. Aesthetically, it abandons curves for sharp lines and square dual headlights. In 2013, it benefited from one of the most expensive facelifts in automotive history (over a billion euros in investment), unifying the front headlights and profoundly modernizing the interior and powertrains. Although this sheet focuses on petrol engines (which underwent a major transition from indirect injection to CGI direct injection, then the arrival of the turbo), the W2
✅ Strengths
- Manufacturing and finish quality significantly improved compared to the W211
- Exceptional ride comfort, especially with Airmatic suspension
- Very high level of cabin sound insulation
- Overall very satisfactory reliability of the onboard electronics
- Excellent corrosion resistance
- Particularly successful and reliable V6 petrol engines (M276)
⚠️ Weaknesses
- Fragile M271 4-cylinder petrol engine (2009-2013) (timing chain)
- High maintenance and spare parts cost in the official network
- Airmatic air suspension (optional or standard on estate rears) prone to leaks (air springs, compressor) after 100,000 km
- 7G-Tronic automatic gearbox sometimes slow and prone to jerks if not serviced
- Blind spot sensors in the rear bumper that take on water and fail
- Decorative wood trim (burr walnut) that dulls and whitens with UV exposure (varnish defect)
🎯 Verdict
The Mercedes E-Class W212 is an excellent vintage that has restored the brand's reputation for reliability. If you are looking for a petrol engine, the top choice is the 3.5 V6 (M276) from the post-2011 E 300 and E 350, which offers exceptional driving pleasure for high-level reliability. For 4-cylinders, avoid 2009-2013 models equipped with the M271 engine (E 200 CGI, E 250 CGI) unless the timing chain has been completely redone. Prefer facelifted versions (from 2013) equipped with the much more robust M274 engine. V8 versions are exhilarating but require a significant maintenance budget, with particular vigilance on the V8 BiTurbo (M278). Overall, a well-maintained W212, ideally in its facelifted (Phase 2) version, is a highly recommendable purchase that ages remarkably well.
