Ford recalls 1.48 million F-150s for transmission, plus other models

Weeks after recalling more than 800,000 F-Series pickup trucks for a fire risk, Ford has issued another separate recall for approximately 1.48 million 2011-2013 F-150s for a transmission fault. The six-speed automatics could unexpectedly downshift into first gear without warning. Ford and Lincoln tangentially issued much smaller recalls for the Mustang, Continental, Nautilus, and Navigator. According to Ford, some 2011-2013 model year F-150 pickups with six-speed automatic transmissions could "experience an intermittent loss of the transmission output speed sensor signal to the powertrain control module." This could potentially cause the trucks to temporarily downshift, which could be dangerous if it occurs while driving. Of the 1.48 million affected trucks, 1.26 million are in the U.S. while 221,000 are in Canada. Thus far, Ford knows of five reported accidents involving the issue. To remedy the problem, owners can take their trucks to dealers to update the power control module software. Ford also issued recalls for about 4,350 2019 Mustangs, Lincoln Nautiluses, and Lincoln Navigators in the U.S. and Canada due to a possible fault with the instrument clusters. Although there have been no reports of accidents, Ford says the instrument panel clusters assemblies might be blank or not turn out when the vehicle is started. Additionally, Ford issued a third recall for 28,200 2017-2019 Lincoln Continentals in the U.S. and Canada. Ford says silicon contamination might build up inside the door latch motor, causing it to malfunction. As a result, the door latch might not always fully engage, and the doors could possibly open unexpectedly. Despite no reports of accidents, Ford will remove and replace door latch assemblies on all doors for those affected by the defect. If any of these apply to a vehicle you own, contact Ford to discuss whether it is included in any of these recalls and have the vehicle checked out at a Ford dealership.

Ford wants smart cruise that's speed and grade sensitive

Ford is working to make adaptive cruise control even smarter and more economical for future vehicles. The automaker now has a patent (pdf link) on a system to use information on the grade of the road, traffic data, and a driver's preferences to eke out better fuel mileage over a journey. This solution would essentially put a little hypermiling right into a model's software. The Blue Oval's patent refers to this tech as "route navigation with optimal speed profile," and the system starts by splitting the way to the driver's ultimate destination into many smaller pieces. Each one is analyzed based on GPS data, and traffic info is also constantly updated. Based on the occupants' preferred travel time, all this info is combined to figure out the most efficient speed for each leg of the journey. All of these calculations are actually more than the car's computers can handle, so some of the math is offloaded to a cloud-based network. According to Ford, some of the benefits come when tackling hills while diving. Maintaining a single speed when going up and down steep grades isn't the most efficient method, but current technology can't easily make the necessary adjustments. This system uses the GPS data to adapt the vehicle's speed and leave the situation with better fuel economy. Ford is currently making major investments into autonomous driving technology and has some prestigious partners. While the patent documents don't specifically mention the optimal speed profiles for driverless vehicles, they seem like a natural fit. Over the course of an entire trip, the fuel economy gains would likely be even greater than over a few miles on a relatively flat interstate.

The 24 Hour War: Adam Carolla's new documentary brings the Ford-Ferrari battle back to life

Long before the GoPro or even videotape, races were filmed by guys standing next to the track with 16-millimeter cameras. The images kind of shook, they didn't always hold focus, and over the years all the color has faded out of the film. It all conspires to make the endurance racing battle between Ferrari and Ford in the 1960s seem like ancient history. What Adam Carolla and Nate Adams' new documentary The 24 Hour War does best is make that inter-corporate battle feel as if it happened yesterday. Yeah, if you're an obsessive you've likely seen most of the shaky-cam race footage used here before. But what you haven't seen are the interviews that frame the war and explain the egos and engineering behind the legends. It's not a perfect movie, but it's the sort of movie only fanatics could make. And it's easier to appreciate if you're a fanatic too. The first 25-or-so minutes of the documentary are taken up with histories of both Ford and Ferrari and an overview of how ridiculously deadly motorsports were in the Sixties and earlier. It's all interesting (if familiar) stuff, that could have been handled in about a third the time with some brutal editing. Still, the two protagonists in the story are well drawn: the racing-crazed Enzo Ferrari, who only builds road cars to stay solvent; and Henry Ford II, who after being thrown into the deep end of the Ford Motor Company management in 1943 at the age of 25, wasn't going to be humiliated after Ferrari pulled out of a deal to sell him the sports car maker. With one notable exception, the filmmakers were successful in rounding up practically everyone involved who is still alive for an interview. That includes Dan Gurney, Mario Andretti, Pete Brock, Bob Bondurant, Piero Ferrari, Mauro Forghieri, Carlo Tazzioli, and even Ralph Nader. There are good archival insights from the late Carroll Shelby. But where's A.J. Foyt? After all, he co-drove the stupendous Ford GT40 Mark IV with Dan Gurney to victory at Le Mans in 1967. The interviews make the movie worthwhile, but it cries out for more technical depth about the cars themselves. Yes, the GT40 was complex and engineered practically like a production car, but there's no mention of how the Lola Mk VI and Eric Broadley kicked off the development. There's only a superficial explanation of what made the American-built Mark IV such a leap forward.
