Credov's researched list of the 4 faults the Nissan Q50 Hybrid is known for (2014–2022), 4 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Check the brake pedal is firm, does not sink, and braking is smooth with no grabbing or surge.
Why it matters: A failing electric brake booster reduces braking performance, which is a safety risk, and the pedal sensor is not sold separately so the whole booster has to be replaced.
What to look for: Check the engine joins in smoothly from electric drive with no jerk, flare or clutch fault code.
Why it matters: A slipping dry clutch gets worse over time, and the gearbox has to come out to fit a new clutch disc, a major and costly repair.
What to look for: Check the battery gauge rises and falls normally and EV-only running has not become weak or short.
Why it matters: A worn hybrid battery is very costly to replace, and used or rebuilt packs are hard to find for this model.
What to look for: Run the air-con on max cold with the engine on and stopped and check it stays cold throughout.
Why it matters: The electric air-con compressor is an expensive part with few rebuilt units available, and a seized unit can spread debris through the whole system.
