Ford recalls 90,736 vehicles due to engine valve issue

Ford will recall 90,736 vehicles as engine intake valves in the vehicles may break while driving, the National Highway Traffic Safety Administration (NHTSA) said on Saturday. The recall impacts certain 2021-2022 Bronco, F-150, Edge, Explorer, Lincoln Nautilus, and Lincoln Aviator vehicles equipped with either a 2.7L or 3.0L Nano EcoBoost engine, the NHTSA said. According to documents posted by NHTSA and sourced from the automaker, "The engine intake valves may break while driving, which can result in engine failure and a loss of drive power." Following an investigation that started in January, 2022, Ford found 22 instances where "the engine intake valves fractured and fell into the combustion chamber of the engine causing catastrophic engine damage." The automaker's analysis continues: "Ford identified that the potential root cause of the failures was engine intake valve failure due to valves that exceeded the designed specification for hardness, were brittle, and more likely to fracture. Ford determined that this was due to the supplier’s grinding processes and the sensitivity of the intake valve material to grinding processes that were not within control specifications. The intake valve material was changed for vehicles produced after October 31, 2021." Fixing the problem will require replacement of the entire engine. "Dealers will inspect each vehicle to determine its cumulative number of engine cycles. For vehicles that do not meet the engine cycle threshold, dealers will accumulate high revolutions per minute (rpm) engine cycles per a service procedure. Engines will be replaced on vehicles that do not pass the engine cycle accumulation," Ford says.

Google's new Android Autos OS unveiled, will be in cars this year [w/video]

Connected cars are coming en-masse. We know this much. How, though, remains something of an open question, especially as two of the world's largest tech companies are preparing to battle for control of your car's dashboard. On the one hand, we have Apple and its CarPlay system. And now, we know what Google has been working on with Auto Link.
Its new name is Android Auto, and yes, it's based off the Android architecture that is the primary challenger to Apple's iOS mobile operating system. Announced at Google's I/O conference today, Android Auto functions similarly to CarPlay - owners will need to plug their smartphones into their cars to access the full breadth of capability.
In Android Auto's case, that means a wealth of voice controls to limit distracted driving. Google's marquee apps will be available when the interface arrives in production models later this year, including Google Play Music, Google Maps and voice-activated texting and text playback. Meanwhile, developers will be able to begin designing custom apps for the new system via an upcoming software development kit.

Is it time for American carmakers to give up on dual-clutch transmissions? [w/poll]

Last week, in the midst of Detroit's first days seeking relief in Chapter 9 of the bankruptcy code, Automotive News contributor Larry P. Vellequette penned an editorial suggesting that American car companies raise the white flag on dual clutch transmissions and give up on trying to persuade Americans to buy cars fitted with them. Why? Because, Vellequette says, like CVT transmissions, they "just don't sound right or feel right to American drivers." (Note: In the article, it's not clear if Vellequette is arguing against wet-clutch and dry-clutch DCTs or just dry-clutch DCTs, which is what Ford and Chrysler use.) The article goes on to state that Ford and Chrysler have experimented with DCTs and that both consumers and the automotive press haven't exactly given them glowing reviews, despite their quicker shifts and increased fuel efficiency potential compared to torque-converter automatic transmissions.
Autoblog staffers who weighed in on the relevance of DCTs in American cars generally disagreed with the blanket nature of Vellequette's statement that they don't sound or feel right, but admit that their lack of refinement compared to traditional automatics can be an issue for consumers. That's particularly true in workaday cars like the Ford Focus and Dodge Dart, both of which have come in for criticism in reviews and owner surveys. From where we sit, the higher-performance orientation of such transmissions doesn't always meld as well with the marching orders of everyday commuters (particularly if drivers haven't been educated as to the transmission's benefits and tradeoffs), and in models not fitted with paddle shifters, it's particularly hard for drivers to use a DCT to its best advantage.
Finally, we also note that DCT tuning is very much an evolving science. For instance, Autoblog editors who objected to dual-clutch tuning in the Dart have more recently found the technology agreeable in the Fiat 500L. Practice makes perfect - or at least more acceptable.
