Brake Actuator Assembly Failure: The symptoms may be reduced braking performance or warning lights on the instrument cluster.
Here are some of the latest issues that we’ve found whilst servicing Hybrid and EV vehicles. Not all makes and/or models have the same issues, but these are the ones that seem to crop up regularly.
The Toyota Hybrid Brake Actuator is a major part of the braking system in Toyota hybrid vehicles. It’s responsible for controlling the regenerative braking and hydraulic braking functions of the vehicle.
In a Toyota hybrid, the braking system operates in conjunction with the hybrid drive system to maximize energy efficiency. When you apply the brakes, the Brake Actuator controls the transition between regenerative braking and traditional hydraulic braking.
During regenerative braking, the electric motor acts as a generator and converts the kinetic energy of the vehicle into electrical energy. This energy is then used to charge the hybrid battery. The Brake Actuator helps manage this by controlling the amount of braking force applied and regulating the interaction between the electric motor and the wheels.
If the braking force required exceeds what can be achieved through regenerative braking alone, the Brake Actuator automatically transitions to hydraulic braking. It activates the hydraulic brake system, which applies pressure to the brake pads or shoes, allowing for additional stopping power.
The Brake Actuator incorporates various components, including hydraulic actuators, solenoid valves, sensors, and an electronic control unit (ECU). These components work together to ensure the smooth operation of the hybrid braking system.

Electric Power Steering (EPS) Failure
There have been instances where the electric power steering system in Toyota Camry Hybrid models has experienced problems. This causes a loss of power assistance while steering, which can lead to heavy steering requiring a lot of effort to turn the steering wheel making it difficult but not impossible to control the vehicle.
Toyota Camry Electric Power Steering (EPS) failure can show up in several different ways.
Loss of Power Steering Assistance: The most noticeable symptom is a sudden loss of power steering assistance. The steering wheel may become difficult to turn or feel heavier than usual. This can make it challenging to manoeuvre the vehicle, especially at low speeds or during parking manoeuvres.
EPS Warning Light Illumination: When the EPS system encounters a malfunction, it typically triggers the EPS warning light on the dashboard instrument cluster.
Steering Wheel Vibration or Shaking: Another indication of EPS failure is the presence of vibration or shaking in the steering wheel. You may feel feedback or resistance when turning the wheel, which can affect the overall steering experience.
The main solution for EPS failure depends on the cause. In some cases, it could be a malfunctioning EPS motor or a faulty electronic control unit (ECU). The repair may involve replacing the defective component or recalibrating the EPS system.
If you experience any of these symptoms, please contact Automotive Insight or book an appointment for your car with our technicians We will be able to diagnose the issue accurately and provide appropriate solutions.
Toyota and Lexus High Voltage Battery Thermal Management Air Filter
Lexus and Toyota hybrid vehicles are equipped with a High Voltage (HV) Battery thermal management system that helps regulate the temperature of the battery pack. The system includes an air filter that prevents dust and debris from entering the battery compartment and interfering with the cooling and heating functions.
Maintenance of the HV Battery thermal management air filter is an important aspect of keeping the system functioning optimally.
Guidelines for HV Battery Thermal Filter Management
The air filter needs to be regularly inspected for any signs of dirt, debris, or damage. This inspection can be done during routine maintenance.
Depending on the vehicle model, the HV Battery thermal management air filter may be reusable or require replacement. If it is a reusable filter, it can be cleaned using compressed air or by gently tapping it to remove dust and debris. However, if the filter is damaged, excessively dirty it should be replaced according to the manufacturer’s recommendations.
The frequency of air filter maintenance may vary depending on driving conditions and climate but it is recommended to inspect and clean or replace the HV Battery thermal management air filter at regular service intervals, which are specified in the owner’s manual.
At Automotive Insight we perform the HV Battery thermal management air filter checks as part of our comprehensive maintenance schedule and is often overlooked by inexperienced service centres. We have the expertise and knowledge to ensure proper maintenance and address any concerns related to the HV Battery thermal management system.
Tyres specifically made for EV’s and Hybrids
Electric vehicles (EVs) and hybrid cars have unique characteristics that can necessitate special tyres designed specifically for their needs. Below are some of the reasons why EVs and hybrids can require specialised tyres:
Weight Distribution
EVs and hybrid vehicles typically have heavy battery packs usually located in the floor of the vehicle, which can result in different weight distribution compared to conventional internal combustion engine (ICE) vehicles. Specialised tyres can be designed to handle the specific weight distribution of these vehicles, providing optimal traction, stability, and handling.
Instant Torque:
Electric motors in EVs deliver instant torque, which means they can accelerate quickly. This can put additional strain on tyres, requiring them to have enhanced grip and traction capabilities to handle the sudden and strong acceleration.
Regenerative Braking
EVs and hybrids often utilise regenerative braking, which captures kinetic energy during braking and uses it to recharge the battery. This type of braking puts different demands on tyres compared to traditional friction braking, as it can result in varying levels of grip and traction. Tyres designed for EV’s and Hybrids can provide consistent performance and grip during regenerative braking.
Rolling Resistance
Electric vehicles place a greater emphasis on efficiency and maximising range. EV and Hybrid tyres can be engineered to have lower rolling resistance, meaning they require less energy to move, thus improving the overall efficiency and extending the vehicle’s range.
Noise Reduction
EVs and hybrids tend to be quieter compared to ICE vehicles because they lack the noise associated with an internal combustion engine. As a result, tyre noise becomes more noticeable. Specialised tires can be designed with noise-reducing features to minimise road noise and provide a quieter driving experience.
It’s important to note that all EVs and hybrids require specialised tyres, and tyre selection can also depend on factors such as the vehicle’s weight, performance characteristics, and the driving conditions you typically encounter.
