Toyota C-HR2017

Known issues

• 1.2T petrol turbocharger carbon build-up on direct injection at high mileage (80k+), causing rough idle and reduced power — preventative fuel system cleaning recommended
• Timing chain tensioner rattle on cold start in first 5–10 seconds, particularly in winter; rare but documented in some 2017–2018 units — requires chain replacement if severe
• Occasional CVT transmission shudder during low-speed acceleration or hill starts; reprogramming via software update usually resolves
• Panoramic sunroof seal deterioration after 6–7 years, leading to minor water ingress at rear roof edge and interior trim staining
• 12V auxiliary battery discharge issues if car left idle for 2+ weeks; parasitic drain from infotainment system reported in some vehicles
