Mazda CX-5 Engine Problems
What may have caused my Mazda CX-5 to suddenly stall?
There are literally hundreds of things that could have caused the engine to suddenly stop. It could be anything from an electrical failure to a broken crankshaft to a seized torque-converter to an empty fuel tank. And practically anything in between. The dash lights illuminating when the engine stopped is actually quite normal, as the lights are trying to warn you that something’s wrong (in case you hadn’t noticed).
The fact that it won’t restart is no real clue, either, as you haven’t told me whether the engine turns over and won’t fire, or won’t turn over on the starter at all.
What is the best family SUV for around $20000?
While the Mitsubishi Outlander is spacious, reliable and easy to drive, our experience testing it against rival medium SUVs have found it to be noisy and a little too firm riding to be truly comfortable and relaxing. At your price point, there are better alternatives out there.
Have you considered a Mazda CX-5? In petrol or diesel, we have found it to be a superior and more economical proposition, and is definitely quieter and more refined. Plus, the Mazda's all-wheel-drive system is more sophisticated and better at dealing with loose surfaces like sand.
A late-model (post 2014) S5-series Subaru Forester 2.5i petrol is far more economical than the earlier iterations, since it switched to a more efficient CVT continuously variable transmission. And there's also the 2.0D turbo-diesel which is economical. This, too, is a fine SUV on-road or for light off-road driving.
Finally, the Nissan X-Trail diesel is a roomy and capable choice, especially from 2017, when it received a 2.0-litre turbo-diesel to replace the older 1.6L unit.
What oil should I use for my Mazda CX-5 2019?
Mazda recommends fully synthetic for its SkyActiv engines and 5W30 is one viscosity that is listed for this engine. It’s also worth noting that the Mazda engine requires oil that conforms to API (American Petroleum Institute) SL, SM or SN. Although these gradings have an American tag, they’re pretty universal in the industry and denote an oil that is up to a certain minimum standard of protection required by car-makers (Mazda included).
But before I bought any oil, I’d contact the workshop or dealership that did the most recent oil change or service and ask what brand and grade of oil was used. That way, you’re not mixing oils. Different oils have different additives, and mixing them can sometimes cancel out the benefits of these additives.
There may be those reading this who will question whether a new car like a 2019 Mazda should be needing top-up oil between oil changes. But it’s a fact of life that even modern, high-tech engines do consume a little oil between services. Modern all-alloy engines are possibly even a little oil-thirstier than their old-school, cast-iron predecessors. A smart car owner still makes a habit of dipping the engine oil every Saturday morning.
I’d also recommend using a quality, brand-name oil rather than the cheaper, supermarket-branded stuff. Oils ain't oils? Definitely not.
Mazda CX-5 or Hyundai Tucson: Which has better fuel consumption?
Fuel consumption is a difficult subject because there are a number of things that affect it that relate to you and the sort of driving you do, but the official fuel consumption figures come down on the side of the Mazda, 7.4 L/100 km compared to 7.7 L/100 km average for similar vehicles. Either one would be a good choice, but if fuel consumption is your determining feature then go for the CX-5.
Mazda CX-5 2014: Does it need a special battery?
It doesn’t need a special battery; a good quality one will do the job.
How to change the oil on a Mazda CX-5?
The principals of changing any fluid, including engine oil, in cars hasn't really changed in the last 70 years. Warm up engine, remove filler cap, drain old oil into a pan, swap oil filters, refill oil to recommended level using the oil grade recommended by the manufacturer. However, if you get something wrong in that process there is a real risk of injury or causing (financially) catastrophic damage to your car, so I'd suggest newbies take their cars back to the dealership, or a good independent mechanic, to have a professional do the job for you. They can also give your car a once-over to ensure nothing else needs repairing, or will wear out soon!
Mazda CX-5: Why has the ISTOP function stopped working?
Intermittent problems are hard to fix because the mechanic really has nothing to go when everything is working. It could be an electrical connection, or a sensor. The only thing you can do is to persist and take it to the dealer when it happens again.
Mazda CX-5: Faulty alternators
If you’d had your car serviced by the Mazda dealer you would have saved yourself the cost of the replacement alternator, and the inconvenience of trying to sort it out.
