Historical MOT pass rates and DVLA records for 2016 model year cars.
- Engine Bay High-Voltage Wiring Harness Chafing and Short CircuitSerious
On 2016 to 2018 Prius models, the engine wiring harness connected to the hybrid Power Control Unit (PCU) can rub against its protective cover due to assembly tolerances. Prolonged engine vibration can wear through the wire insulation, exposing copper strands and generating an electrical short circuit that causes stalling or poses a severe vehicle fire hazard under DVSA recall R/2018/240.
- Auxiliary 12V Battery Parasitic Drain and No-Start ConditionModerate
The small auxiliary 12V AGM/EFB battery responsible for booting the hybrid system ECUs and vehicle relays suffers from parasitic drain when the vehicle is parked unused for several days. Because the hybrid system does not use a conventional alternator, short urban journeys fail to recharge the 12V battery, resulting in a completely dead car that cannot switch to READY mode.
