2025 Toyota RAV4 Pricing and Specs

Without a doubt, the best thing to do now is the have the car electronically scanned. That’s because there are literally hundreds of things that could cause this sort of problem, ranging from (but hardly limited to) a sick fuel pump, a blocked fuel filter, worn injectors, a fuel leak, poor ignition, a low-voltage battery, dirty air-filter, blocked or damaged exhaust, a stray electrical problem and much, much more. Even something simple like a fuel rail that is not holding pressure when the engine is switched off, can lead to symptoms very much like yours.

Hopefully, the on-board computer has logged these random starting problems and will be able to tell a mechanic what’s wrong. Otherwise you’ll simply continue replacing parts that weren’t the problem in the first place. And that costs time and lots of money.

The kerb weight of the RAV4 you mentioned depends on whether it’s the two or four-wheel-drive model. If it’s the former, the kerb weight is 1690kg, if it’s the all-wheel-drive model, the kerb weight is 1775kg. I know you asked for tare weight, but the only difference between kerb and tare weight sis that tare weight is the mass of the empty vehicle with 10 litres of fuel in its tank, while kerb weight is the same empty vehicle but with a full tank of fuel.

Of perhaps more interest to anybody towing is the fact that the two-wheel-drive RAV4 can tow 480kg while the AWD version can cope with 1500kg. The 2WD Rav’s GVM, meanwhile, is 2185kg and the AWD’s is 2230kg. The two-wheel-drive RAV4’s GCM is 2665kg, while the all-wheel-drive’s GCM is 3730kg.

Some of this information is quite difficult to find (even if you have the owner’s manual) yet it’s crucial safety information and should be more readily available. Some car makers seem very coy about publishing GVM and GCM limits, possibly because they don’t always reflect well on the product’s ability to tow and carry a load at the same time.

A noise or vibration that is engine speed dependent is usually associated with the driveline, while a similar problem that occurs at a particular road speed is more often a problem with a wheel or suspension component. The main exception to that is the differential which is part of the driveline but determines the vehicle’s speed, so can contribute a speed-dependent noise or vibration, too.

Beyond that, you could be looking at a fault with a wheel bearing, a deformed tyre, bent rim, worn suspension bush, bent axle or suspension arm or pretty much anything else. A rolling-road dynamometer (kind of like a treadmill for cars) might be one way of achieving the problem speed while a mechanic looks and listens on.
