Question 1

My 2019 Honda CR-V's fuel efficiency is getting worse

Accepted Answer

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.

Question 2

Thinking about a Honda CR-V and its engine service life. Does the engine have a timing belt or chain?

Accepted Answer

Is the engine in your Honda CR-V timing belt or chain? It depends on when the car was made, but it’s crucial information. That’s particularly so for owners of the first-gen CRVs we saw in Australia. That vehicle had the B Series Honda engine which used a rubber timing belt. The good news is that this has proved a very reliable set-up, and Honda recommends the belt be changed only every 150,000km which is a huge replacement interval by industry standards. A full kit to replace the timing belt on this engine, including a new water pump, will cost around $300 for the parts After that (from 2001 onwards) Honda fitted the K Series engine to CRVs, and this engine used a timing chain which should be good for the life of the engine. The R20A four-cylinder engine used from late 2012 also uses a timing chain, as does the turbo-diesel 2.2-litre engine from the same era. The current-model CR-V with its 1.5-litre turbocharged petrol engine (the L15B7) also uses a timing chain. The task of the timing chain or timing belt is exactly the same: They take drive from the engine’s crankshaft to the camshaft and, in the process, keep all the moving parts in harmony. Many car makers moved away from a timing chain to the rubber, toothed drive belt as a way of simplifying engine design and driving down the cost of each engine. The rubber timing belt is also quieter in its operation and is also less prone to stretching (as a timing chain can) so the camshaft (commonly referred to as the cam) stays in perfect synch with the rest of the engine’s rotating parts. The rubber timing belt is a simpler design because it doesn’t need to be tensioned via oil pressure from the engine as many timing chain systems are. The timing chain, meanwhile, is preferred by some manufacturers because it should last the lifetime of the engine and never need replacement. This isn’t always the case, however, and some engines designs from a variety of manufacturers suffer problems in this regard. But, in a properly maintained engine of sound design, the timing chain should never need attention, while the rubber timing belt generally requires periodic replacement.

Question 3

What's wrong with my 2006 Honda CR-V engine?

Accepted Answer

The engines in these Hondas are considered pretty solid and reliable performers. But as with any car now celebrating its 15th birthday, things can go wrong that can affect performance. With that in mind it could be time to give the engine a comprehensive once-over and a full service. Having the car electronically interrogated would be a good idea, too, as any faults noted by the on-board computer will have been logged and could tell you a lot about that’s going on under the bonnet. Just because the car hasn’t illuminated a dashboard warning light, doesn’t mean that the computer hasn’t noticed something strange going on. The problem is obviously an intermittent one (or the car would never run properly) and that really does point towards something electronic. That said, a good mechanic will also go back to first principles checking things like fuel delivery, ignition timing and even engine compression. Any information you can gather when the problem occurs will help enormously, too. For instance, does the engine blow smoke or make any odd noises when it loses power? Does the car shudder or suddenly start using more fuel when the problem occurs? The more observations you can pass on to a mechanic the better idea he or she will have of where to start searching. Fundamentally, you could be looking at anything from a collapsed catalytic converter or muffler, a faulty fuel pump or injector, a damaged spark-plug lead or literally any one of about a thousand other things.

Question 4

What's the correct oil type for my Honda CR-V, and is it tricky to change it yourself?

Accepted Answer

The best Honda CR-V engine oil will depend on which engine your car is fitted with. From 2007, Honda used a 2.4-litre four-cylinder and, even though the model was facelifted in 2012, the engine stayed the same. In that case, the oil you need is a quality (from a recognised brand) 5W40 either synthetic or semi-synthetic. From 2012 to 2017, the CR-V was also available with a two-litre petrol engine option, and that unit requires a 0W20 as the first choice but a 5W30 is also allowable for engines that size. If your car is the later model, things get a bit more complicated as there were new engine options including a 2.2-litre turbo-diesel which needs a diesel-specific 0W30 synthetic oil. If you have the later 1.6-litre turbo-diesel replacement which arrived here from late 2015, the same 0W30 oil is appropriate, as is a 5W30 synthetic. These `light’ (low viscosity) oils are typical for high-tech engines such as the Honda’s with its variable valve timing. Honda made continual changes to the CR-V range over the years, including some model and specification revisions for the 2016 model year, but none of these affected the range of engines (or Honda CR-V oil type) we’ve just discussed. Late model CR-Vs with a petrol engine require five litres (or slightly less) of oil, while the turbo-diesel models need 4.7 litres. Just as there’s a correct Honda CRV oil, the correct Honda CR-V oil filter should also be fitted at the same time to avoid putting clean oil through an old, dirty filter. For the 2.4 petrol, the correct filter is a Ryco (or equivalent) Z411, as is the filter for the two-litre petrol. The 2.2-litre diesel requires an R2767P filter while the 1.6 diesel uses a Z690. There are no mysterious trade secrets about how to change oil on a Honda CR-V, but you do need to know the basics. Changing oil and oil filter at home is a great DIY project and a good way to save some money and gain some satisfaction. The best advice is to obtain a workshop manual specific to your car and take it step by step. The manual will also include all the information and specifications you need to tackle other DIY service and maintenance jobs including checking power steering and transmission fluid. The manual will also give you information on how often to change the oil as well as the check and service intervals for the car’s other systems. That way, you won’t be relying on a warning light on the dashboard to tell you that action is needed. If you have any doubts, there’s always the option of taking the vehicle to a service centre, but even talking to a family friend who is a mechanic might give you the confidence to give this task a go. Changing a car’s oil is not tricky, but there are things you must remember, including disposing of the used oil in an environmentally responsible way.

Question 5

Why is the plastic around the gear shift on my 2019 Honda CR-V deforming?

Accepted Answer

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.

Question 6

Honda CR-V 2020: Should I buy AWD?

Accepted Answer

It’s a fact that the top-rung version of a particular make and model will not only get all the luxury and convenience items, it’ll also usually be the first to score new safety tech, too. That’s why CarsGuide gives car-makers a pat on the back when they make new safety gear standard across the whole range. However, that’s the exception rather than the rule here, and most car-makers, including the ones you’ve mentioned have the same policy of loading up the more expensive variants in their line-up. But before you dismiss all-wheel-drive as something you have to pay for to get better safety gear, understand that AWD itself is a safety boost. The extra grip given by driving all four wheels makes a car safer in all conditions, but especially in low-friction conditions. So, if safety is a concern (and it obviously is for you, Mark) then I reckon AWD is for you anyway. Besides which, even though you’ve said you only driver to the snow every now and then, when those times arrive, you’ll be very pleased you paid for AWD.

Question 7

Should I buy a Toyota RAV4 or a Honda CR-V?

Accepted Answer

You really need to go out and test drive both vehicles, because they both have their plusses and minuses and those will be graded according to your personal preferences. Overall, the RAV4 is a bigger vehicle (almost as big as the original Kluger, in fact) so that might come into the reckoning based purely on the size of your parking space at home. The RAV4 rides a bit more softly but your choice of the range-topping VTi-LX in the Honda is a good one because that’s the only model in the line-up that includes autonomous emergency braking, lane-keeping and adaptive cruise-control. That said, the RAV4 has all those features, too, but extends them to the bulk of the models offered, not just the top-spec version. On warranty and fuel economy, both compare pretty closely, so it will come down to the little things that you personally find important; things like the Honda’s doors that open almost to 90-degrees and the Toyota’s vast rear seat legroom and cavernous luggage space. Over to you.
