Toyota C-HR 2.0 Hybrid
2.0-litre fifth-generation hybrid drivetrain with high efficiency. Noticeably more powerful than the 1.8 hybrid, yet barely thirstier. Lithium-ion battery, E-CVT, no known weaknesses so far.
Mature design SUV
145 kW 2.0 hybrid in the refined AX50 — sporty chassis, dynamic drivetrain and finally a coherent overall package.
Engine Weaknesses 7
The EGR cooler can develop cracks, causing coolant ingress into the combustion chambers. Toyota has published TSBs for affected models. EGR valve sticks from around 100,000 km.
Symptoms: White smoke from exhaust; coolant loss; sweet exhaust smell
The EGR liquid cooler on the M20A-FXS can allow coolant into the combustion chambers through internal leaks. Toyota has issued a TSB (T-SB-0104-21).
Symptoms: White smoke from exhaust, coolant level dropping without visible external leak, oil turns milky, engine warning light
All Dynamic Force engines are susceptible to EGR cooler cracks per TSB EG-00691T-TME. On the M20A-FXS, coolant can enter the combustion chamber and cause hydrolocking, cylinder head damage or piston deformation.
Symptoms: White smoke from the exhaust, coolant loss without visible external leak, engine stumbling, engine damage in severe cases
From around 80,000–100,000 km, the EGR valve and EGR passage on the M20A-FXS can clog with PCV oil vapour and soot particles. Without cleaning, cylinder head damage can result long-term.
Symptoms: EGR fault code P0400, fluctuating idle, poor throttle response, elevated emissions
The M20A-FXS is sensitive to fuel quality. Poor-quality petrol or fuel with high sulphur content causes deposits on injectors, degrading power and economy.
Symptoms: Slight power loss, increased fuel consumption, rough idle, fault code entry for fuel metering.
The EGR valve on the M20A-FXS can block with soot deposits from around 80,000–100,000 km. This leads to fault codes P0401/P0402 and restricted hybrid operation.
Symptoms: Check engine light (P0401/P0402), reduced EGR flow rate, rough idle, in rare cases limp mode.
The M20A-FXS occasionally shows oil loss at engine seals. The complex architecture of the 2.0L Dynamic Force hybrid with direct injection and high-pressure pump increases the risk of seal failure.
Symptoms: Dropping oil level, oil spots under the vehicle, faint oil smell
Vehicle Weaknesses 7
The hybrid battery of the C-HR AX50 can age prematurely during long periods of inactivity or at high temperatures.
The C-HR AX50 can show sporadic EPB error messages. The most common cause is a weak 12V battery. Rarely also software or actuator faults. The EPB may then fail to release.
C-HR AX50 owners criticise the infotainment system as outdated.
Because the C-HR AX50 brakes primarily through regeneration, brake discs rust over quickly.
The low roofline and sloping rear significantly restrict rearward visibility.
Many C-HR drivers report an inaccurate fuel gauge and range display. The indicated remaining range often does not match the actual fuel level. A widely discussed forum topic with 348 replies.
The standard 45 Ah starter battery (factory: Mutlu) drains too quickly on short runs and after extended parking due to permanent consumers (telematics, alarm, GPS). Well documented on chr-forum.de with multiple breakdowns reported.
