Build my inspection planToyota RAV4 · frequently asked questions
Is the Toyota RAV4 reliable?
Yes — it's one of the more dependable compact SUVs, with only minor issues to check.
What should I check on a used RAV4?
Transmission smoothness, service history, and any stored fault codes.
Does the RAV4 have engine problems?
No major engine faults for this generation — it's a strong, long-lasting drivetrain.
Are there any specific issues with the hybrid battery on this generation?
The 2.5-litre hybrid system introduced in 2016 is generally robust, but the nickel-metal hydride traction battery degrades over time. Dealers should check if the vehicle has a full Toyota service history, as this extends the hybrid battery warranty up to fifteen years, providing significant peace of mind for prospective buyers.
What maintenance is required for the all-wheel-drive system?
The AWD system on these models uses an electromagnetic coupling on the rear differential. It is relatively low maintenance, but the transfer box and rear differential fluids must be replaced every 40,000 miles or four years. Neglected fluid changes can lead to differential whining or premature failure of the coupling.
Why do some diesel models suffer from excessive oil consumption?
Early fourth-generation RAV4s fitted with the 2.0-litre and 2.2-litre D-4D diesel engines can experience piston ring wear, leading to high oil consumption. This is exacerbated by extended service intervals. Always check the dipstick for low oil levels and inspect the service book for annual or 10,000-mile oil changes.
