Honda CR-V RW Hybrid

Honda issued TSB 23-040 acknowledging that the AC compressor shaft seal swells due to a new refrigerant and oil formulation required by regulations. This allows refrigerant to leak out gradually, resulting in warm air from the AC. Affects 2017-2022 CR-V models including the hybrid. Honda extended the warranty on the shaft seal to 10 years from original purchase date with no mileage limit. If within this warranty extension, the repair is free. Out of warranty, replacing the compressor costs approximately €800-1,200 at a dealer, or €400-600 at an independent specialist. The shaft seal alone is a minor part, but labor to access and replace it is significant.

The CR-V hybrid's electronics maintain a parasitic draw of approximately 50 milliamps when parked. The keyless entry system, connectivity modules, and hybrid system monitoring all remain active. If the car sits unused for more than a week, the 12V battery can go flat, preventing the hybrid system from starting. This is especially common on 2019-2021 models. Honda released a software update to reduce parasitic draw. A replacement 12V battery costs €150-250, but the underlying draw issue should be addressed with a dealer software update first. Using a trickle charger (CTEK or similar) when parked for extended periods is strongly recommended.

NHTSA has investigated Honda's Collision Mitigation Braking System across multiple models, with over 1,200 complaints filed. The radar sensor in the front grille can misinterpret objects, roadside structures, or shadows, triggering sudden braking at highway speeds. Honda has attributed some occurrences to radar misalignment and instructed dealers to reposition the sensors. A software recalibration at the dealer typically costs €100-300, though Honda may cover it under warranty or goodwill. The system can be temporarily disabled, but it re-enables each time the car is started. NHTSA's investigation expanded to cover nearly 3 million Honda vehicles.

Owners report the infotainment screen going completely black for up to 20 minutes or freezing and becoming unresponsive. This affects navigation, the reversing camera, and audio controls. A soft reset (holding the power button for 10-15 seconds) usually resolves it temporarily. A dealer software reflash is the recommended permanent fix and is often covered under warranty. In rare cases where the head unit hardware has failed, replacement costs approximately €500. Honda issued TSB 19-066 addressing display issues on affected models.

Hybrid braking systems blend regenerative and friction braking. At very low speeds (below approximately 10 km/h), the system transitions from regenerative to conventional friction brakes, which can cause a noticeable grabbing sensation or moaning sound. This is partly because the friction brakes are used less frequently in a hybrid, allowing surface corrosion to build up on the rotors. The issue is more pronounced in damp conditions. Dealers sometimes state this is normal behavior. If the noise is excessive, resurfacing or replacing the front brake discs (€200-400) and pads (€100-200) can help, though the issue may return over time.

Honda recalled certain 2020 CR-V Hybrid models because transistors in the power converter unit contained excessive dopant concentrations. In cold temperatures, this caused abnormally high voltage output that triggered a protective shutdown of the DC-DC converter. With the converter offline, the 12V battery could not recharge, eventually leading to loss of drive power. Honda addressed this with a free software update (recall 20V798). If you are looking at a 2020 model, verify this recall has been completed. The fix is purely a software update at no cost.
