2.0L turbo with 48V mild hybrid — FCA/Stellantis modern four-cylinder. 270 hp, more economical than the V6 (22-28 mpg). Limited long-term data. Coolant hose fitting leak as early issue. 91 octane recommended. Carbon buildup from direct injection possible at high mileage.

• !! Coolant leak / coolant in oil from 60,000 km

• !! Turbo bearing wear from 100,000 km

  Turbo bearing wears prematurely from oil starvation — especially after short trips with no cooldown period or poor oil quality. Direct injection plus turbo: short oil change intervals (max 5k miles) are critical for longevity.

  Symptoms: Whistling from turbocharger, power loss, blue smoke, elevated oil consumption
