What changes compared with the 2010 Lexus CT
The same engines and the same documented faults as in 2010.

The engine itself is reliable, but cars with this version are already between 11 and 17 years old: check that the Prius III campaigns were carried out (brake actuator, hybrid system software) and inspect the condition of wear items (12 V battery, water pump, hybrid battery).[2][3]
Faults that affect 2011 cars
- Critical severityFrequency: OccasionalElectronicsBrake actuator failure (hard pedal, loss of assistance)Yes, it is a documented fault on the Prius III: the diaphragm of the brake actuator's accumulator can degrade and make the pedal very hard, forcing you to brake with much more force. Toyota ran a campaign in 2013; there are also owner reports of actuators failing after the warranty had expired.
- Critical severityFrequency: OccasionalElectronicsThe car loses drive or stalls because of a hybrid system fail-safe mode faultYes. Toyota acknowledged that, in the event of certain internal faults, the hybrid management computer on units built before 2014 might not correctly activate fail-safe mode, and the car would lose drive or stall while driving. It was fixed by software; reprogramming at an official dealer is free.
- High severityFrequency: OccasionalElectronicsInverter (IPM module) overheating and loss of driveYes. On units built between 2014 and 2016, the transistors in the inverter's power module can be damaged by thermal stress and cause loss of drive. Toyota ran a campaign in 2020; there are also inverters that have failed outside the campaign, with repairs of around €3,000.Repair: €3,000
- High severityFrequency: RareElectronicsDegradation or premature failure of the hybrid batteryIt is a component that generally lasts very well (there are units above 300,000 km), but there are isolated cases of premature failure, mainly on the Auris Hybrid, between 77,000 and 80,000 km, with repairs of around €2,800-3,000. We have not found a manufacturer campaign for this.Repair: €2,800–€3,000
Faults outside the engine in the 2011 Lexus CT
- High severityFrequency: OccasionalAirbags and safetyCrack in the evaporative emissions control unit on the tank: leak when the tank is fullYes: Safety Gate records a 2016 alert for a possible crack in the evaporative emissions control unit attached to the tank; with the tank full, fuel could leak and, given an ignition source, cause a fire. In the United Kingdom, the campaign covers CT 200h vehicles built between August 2010 and February 2015.
- High severityFrequency: OccasionalAirbags and safetyAirbag inflator for the curtain airbags with a possible micro-crack in the weldYes: a 2016 Safety Gate alert covers CT 200h vehicles produced in 2009-2012 because the weld on the inflator of each curtain airbag may have a micro-crack; if it grows, part of the inflator may separate, partly inflate the airbag and, in limited cases, project fragments into the cabin.
