Toyota RAV4 Hybrid
Flagship fourth-generation hybrid with Dynamic Force technology. Extremely economical for a vehicle of this size (under 5 l/100 km in the Camry). Timing chain, no known weaknesses so far. The gold standard for hybrid reliability.
New hybrid in the old RAV4
145 kW 2.5 hybrid with e-AWD — newer technology than the 2AR, good pull from rest. The most recommendable XA40 drivetrain.
Engine Weaknesses 6
The hybrid battery in the RAV4 XA50 with A25A-FXS sits under the rear seat and can be damaged by moisture. Blocked ventilation slots lead to battery overheating.
Symptoms: Hybrid warning light, reduced battery output, 'Check Hybrid System' message, in severe cases complete battery failure
The EGR system on the A25A-FXS tends to clog with deposits from approximately 130,000 km. The EGR cooler develops cracks and allows coolant to enter the EGR circuit.
Symptoms: Power loss; foul smell while driving; low coolant level; fault messages on the instrument cluster
The timing chain is considered a weak point on the A25A-FXS and should be inspected preventively at approximately 150,000 km. The frequent engine start/stop cycles in hybrid operation increase the load.
Symptoms: Rattle on start-up; metallic noise from the timing chain area; slightly rough idle
Toyota issued a TSB (T-TT-0614-20) for 2020 A25A-FXS engines: coolant leak at the housing or connector of the electric water pump.
Symptoms: Check engine light, coolant traces on the engine underside, dropping coolant level
In predominantly urban short-trip use the A25A-FXS hybrid engine does not reach operating temperature long enough to drive off fuel and condensation moisture from the oil. Oil dilution and increased bearing wear can result.
Symptoms: Oil level rises instead of dropping, oil smells of petrol, engine oil becomes watery and cloudy, increased wear
The A25A-FXS shares the risk of oil loss at sealing surfaces with other Dynamic Force engines. Long-term data is still limited at high mileage — seals should be inspected thoroughly.
Symptoms: Dropping oil level, oil spots under the vehicle, faint burning smell
Vehicle Weaknesses 10
Heated washer nozzles can allow salt water to enter the heating element through a faulty sealant, which can cause a short circuit and in the worst case a vehicle fire.
The parking brake on the RAV4 XA40 is a known weak point.
The 2.0-litre petrol engine can develop a leaking or seized water pump.
From around 100,000 km the steering rack develops a knocking noise, particularly on rough roads. Replacement with a used or new part is labour-intensive and costly.
Vehicles from salt-heavy regions show paint bubbling at wheel arches, sills and bonnet edges after 7–9 years. Thin factory paint promotes early corrosion.
Vehicles from model years 2014–2015 experienced excessive transmission oil loss due to a production defect. Both manual and automatic transmissions are affected.
The RAV4 XA40 is flagged above-average frequently for headlight issues at roadworthiness inspections.
The A/C condenser in the front bumper area is vulnerable to stone chip damage, causing slow refrigerant loss. The replacement part is costly; if caught early, soldering or sealing may suffice.
Like its predecessor the XA30, the XA40 steering rack cracks when manoeuvring or at full lock. The cause is universal joint wear. Mechanics rate it as a comfort issue.
The XA40 has poor sound insulation around the wheel arches and floor from the factory. After extended use or gravel roads the cabin becomes noticeably louder. Aftermarket sound deadening can be retrofitted.
