Common Toyota C-HR problems, and how to check them

Problem 1
Toyota C-HR: Hybrid won’t switch on: flat 12-volt battery
What goes wrong
The small 12-volt auxiliary battery (not the big hybrid battery) goes flat or wears out, especially when the car stands still or does short trips. Without it the hybrid system can’t switch on.
How to check it yourself
Measure the 12-volt battery: below about 12.2 V at rest it’s flat, and a battery that won’t hold charge overnight is worn. The hazard lights not working or a dead dashboard point to it.
The usual fix
Charge or jump-start from the 12-volt jump point (see the handbook) and replace a worn battery with the correct type. The main hybrid battery is rarely the cause.
Signs: Won’t crank (starter doesn’t turn), Battery warning light, Hard starting
Fault codes: P0562
Problem 2
Toyota C-HR: Grinding brakes from rusty discs (hybrid rarely uses them)
What goes wrong
A hybrid does most of its slowing down with the electric motor, so the friction brakes are hardly used. The discs rust, and the caliper slide pins and rear pads can seize, giving grinding, pulsing, or a brake-test failure.
How to check it yourself
Look at the disc faces through the wheel: a rusty ring or ridges on the braking surface, or pads that don’t move freely, confirm it. Do a few firm stops from speed and listen for grinding.
The usual fix
Clean and grease the caliper slide pins and pad contact points, and replace discs and pads if they’re pitted. Brake firmly now and then to keep the discs clean.
Signs: Steering vibration
Recalls for the C-HR
The most recent recalls registered with the RDW, the Dutch vehicle authority, across all generations of the C-HR. Not every recall covers every car: a dealer can check yours with the VIN (chassis number), and recall repairs are free.
Electric drive system overload
The electric drive system may become overloaded.
Possible consequence: The software of the high-voltage battery may respond incorrectly in certain cases, causing the electric drive system to shut down. The vehicle may lose power while driving.
The fix: The dealer will update the vehicle's software free of charge.
