Common warning signs include the "Maintenance Required" or "Check Engine" light (coolant bypass valve failure with codes P261B or P261C), hybrid system malfunction errors (high-voltage cable corrosion), loss of cabin heat, overheating, and unusual engine noise.

• "Maintenance Required" or "Check Engine" light - coolant bypass valve
• Hybrid system malfunction - high-voltage cable corrosion
• Loss of cabin heat or overheating - thermal management failure

For a Toyota RAV4 2.5 PHEV worth £28,000-£45,000, a rebuilt A25A-FXS engine (£3,800-£5,500 supply) is almost always a sound investment. The RAV4 2.5 PHEV retains strong value, and a quality rebuilt unit with warranty offers better long-term value than scrapping the car or selling it as a non-runner.

• Vehicle worth £25,000+ - replacement is a sound investment

• Supply & fit: 2-4 working days total
• Hybrid system calibration adds some time

The A25A-FXS is generally reliable, but several issues have been documented. The coolant bypass valve can seize (60,000-100,000 miles), the high-voltage cable can corrode ("Cablegate"), and EGR cooler leaks have been reported. Toyota also issued a recall for potential engine cracks in some 2019-2020 models. Regular maintenance and prompt attention to warning lights are essential.

• Generally reliable with proper maintenance
• Coolant bypass valve failure - common high-mileage issue
• High-voltage cable corrosion - known weak point

The RAV4 2.5 PHEV uses the same A25A-FXS 2.5-litre Atkinson-cycle petrol engine as the standard hybrid, but with a larger 18.1kWh lithium-ion battery and more powerful electric motors, delivering 302bhp (38% more than the standard hybrid) and a 46-mile EV range. The PHEV also features a boost converter in the power control unit for enhanced performance.

• RAV4 2.5 PHEV: 302bhp, 46-mile EV range, 18.1kWh battery
• RAV4 Hybrid: lower output, smaller battery, shorter EV range
• PHEV: plug-in charging, higher performance
