Mazda CX-5, Mazda6 and Mazda3 could stall due to software glitch

Mazda is recalling 262,220 vehicles due to a software error that could cause the engine to unexpectedly stall out. The recall affects 2018-2019 CX-5 crossovers, 2018-2019 Mazda6 sedans and 2019 Mazda3 models.  According to NHTSA recall No. 19V497000, which was filed June 27, a programming issue in the powertrain control module (PCM) on select Mazda vehicles could cause the engine to shut down. More specifically, "the software controlling the hydraulic valve clearance adjuster may operate improperly when transitioning from cylinder deactivation to full cylinder activation modes." This could potentially cause the intake valve rocker arm to come out of position and hit something else in the engine. If this occurs, the engine could misfire, the engine could lose power, and the Malfunction Indicator Light would be triggered. The recall affects 143,004 2018 CX-5s, 81,236 2019 CX-5s, 18,295 2018 Mazda6s, 2,551 2019 Mazda6s, and 17,134 Mazda3s. Some cars from those model years received the improved software at the factory and won't be affected by the recall. Although the first report of a related issue was chronicled in January 31, 2018, no injuries tied to the problems have been reported. Mazda is expected to start its recall on or before August 26, 2019, and will reprogram the PCM with improved hydraulic valve adjustment control programming for free.

2020 Mazda CX-5 diesel is still, and perhaps forever, MIA

Halfway through 2020, the most recent Mazda CX-5 diesel you can find anywhere in the U.S. is a 2019 model year — the only one offered so far. With automaker factories beginning their model-year turnovers shortly, CarsDirect did some poking around as to the fate of an oil-burning 2020 CX-5. The outlet couldn't get definitive answers, but a host of secondary evidence suggests the diesel crossover will skip this year, naturally leading to the question of whether the model will skip this market from now on.  Asked in April about the crossover's fate or its arrival, Mazda would only say that "with the current state of the world, many things are tentative." The following month, the automaker's early fleet ordering guide pegged this month as marking the end of CX-5 production, 2021MY crossovers starting down lines in August. Mazda had nothing to say about that information, either. When CarsDirect got in touch again for this latest report, Mazda professed the delay has nothing to do with emissions certification. Then the wall went up again, the only other comment being, "We cannot confirm any details for the CX-5 Diesel at this time."    We're speculating, but at this point, even if Mazda could get 2020MY CX-5 diesels on the lot, why should the automaker bother? The challenges for diesel in general, and this expression of diesel particularly, are clear to everyone; our last post on the CUV, six months ago, was about the five-figure discounts dealers were offering. A quick check on Autotrader at the time of writing shows 45 examples of the 2019 CX-5 diesel available nationwide, plenty of them still priced in the low- to mid-thirties. On Autotrader Canada, which specifies vehicle availability beyond the "1,000+ Results" on the American site, there are 6,135 CX-5s listed nationwide, only 58 of them diesel. Canadian outlet Motor Illustrated wrote, "Mazda recently told us they had a lot of Mercedes-Benz GLE diesel owners and other diesel fans with upscale models trade for a CX-5 diesel." Apparently luxury diesel crossover conquest buyers aren't numerous enough to support a model line. The gasoline versions of the 2020 Mazda CX-5 launched in November last year. It shouldn't take that long for us to find out about the fate of the 2020 CX-5 diesel, or if there will be a 2021 model. Related Video:    

Flyin' Miata is building a V8-powered MX-5 ND

It's cold in many parts of the country, but this V8-swapped 2016 Mazda MX-5 Miata that Flyin' Miata is developing has us dreaming about throwing on a parka and taking a very brisk drive. This beast is the product of the talented folks at Flyin' Miata, but we can't get too excited just yet. According to the company's brief Facebook post, this is just a dummy V8, placed under the Miata's hood to confirm fit. Judging by the photo, the engine fits like a glove. "There's still a long way to go before this is a real thing," Flyin' Miata writes, but the company admits everything looks "very promising" so far. The post doesn't mention any details about the estimated specs, but Autoblog reached out to Flyin' Miata for more information about this intriguing build. Keith Tanner, one of the mad scientists who shoehorns V8s into Miatas at the Colorado outfit, told us that Flyin' Miata is looking at both the LS3, which will provide between 430 and 525 hp, and the LT1 which is 460 hp out of the box. A supercharged LT4 is also being considered, but as Tanner put it, "that might be a little nuts" in a car as light as the ND. In any of these engine configurations, Tanner estimates the V8-swapped ND should comfortably be a sub-4 second to 60 mph car. The transmission will be a Tremec T56 Magnum six-speed manual. The suspension, brakes, fuel system, cooling system, and the chassis itself will all be beefed up to handle the power, as per normal FM practice. The one question mark is the rear end, as the ND's existing one simply won't be up to the task of putting that much horsepower to the ground. The 2016 Miata was one of the best cars we drove in 2015, but Flyin' Miata knows how to turn a standard MX-5 into an absolute hotrod with the company's LS3 V8 conversions for earlier models. Imagining the more modern chassis from the latest generation with a massive dollop of more power is an exciting thought. We can't wait to see how this project turns out. Related Video:
