These two readouts are closely linked in that one determines the other. Your average fuel consumption dictates the distance the car estimates it can travel based on what’s in the tank. But variation in these readings is perfectly normal. That’s because the range estimate is based on your most recent driving. So, if your fuel consumption has jumped from 7 to 8 litres per 100km, the computer will adjust the range down to compensate and prevent you from running out of petrol. That’s all very normal.

The bigger question is why your consumption has recently increased. Have you changed your driving style? Are you suddenly towing a trailer? Have you allowed another driver (with a heavier foot) to borrow the car? Are your tyre pressures correct? Have you added a roof rack? Do you now do more city and suburban driving than before? Is the car in need of a service and tune?

All these things can have a noticeable effect on fuel consumption, and any one of them could be the key to your fuel consumption increase and associated range reduction.

Plastic interior components in Japanese and European cars were once very susceptible to early failures in terms of cracking, peeling, discolouring and warping. The problem was that the manufacturers from these markets had an utter lack of understanding of Australian levels of UV radiation and heat cycles and, as a result, their plastic interiors soon disintegrated. Things soon changed for the better, however, and modern cars have very resilient interior fittings.

However, that makes it even stranger that your car should be exhibiting this problem. I’s not something that we’ve seen across a wide cross-section of CR-V vehicles, so maybe it’s a one-off manufacturing fault. Perhaps the plastic trim piece you refer to was damaged when it was fitted at the factory and has gradually become worse with age. Either way, it should be a simple warranty repair for your local dealership. Replacing the trim piece with a new one is the answer as the damaged part probably can’t be repaired economically.

I can’t think of any reason it wouldn’t be suitable for someone in the 60s. It’s a reputable brand, with good reliability, strong resale. Others to thin about are the Toyota RAV4, Mazda CX5, Subaru Forester.
