FCA UConnect fiasco could set over-the-air updates back years

Since cars have become more software dependent, most major automakers have been inching toward enabling over-the-air updates to keep vehicle electronics, ranging from infotainment systems to safety features, current. But there are only two car companies — Fiat Chrysler and Ford —± currently doing OTA updates, and on a limited basis. GM CEO Mary Barra announced last summer that the automaker will launch a new EV architecture and infotainment system capable of over-the-air updates "before 2020." The one exception, per usual, is Tesla. Since the release of the Model S almost six years ago, the maverick EV automaker has made routine OTA software updates a core part of its vehicle platforms and value proposition, and has sent out updates for everything from adjusting ride height to enabling Autopilot, largely without incident. When I've asked automakers why they can't do the same thing, I've heard reasons ranging from running afoul of their dealers (and archiac regulation) to security concerns. Automakers like Ford and General Motors say they want to act like tech companies, which routinely send out OTA updates for a wide range of devices, but overall the car industry still moves at a very cautious snail's pace. And when automakers do try to move faster and take more risks — unlike with a smartphone update, which people bitch about but live with — the consequences can be significant when things go wrong. That's the case with Fiat Chrysler America and its recent public-relations nightmare when an OTA update went awry. The update went out at the end of last week for the Uconnect system in late-model vehicles, and it made head units go into a near continuous reboot, which caused owners to not only lose access to entertainment features, but also critical functions like emergency assistance. Almost immediately, owners took to Twitter to express outrage, and FCA was caught flatfooted. A tweet went out on Monday on the UconnectCares Twitter account that read, "Certain 2017 & 2018 Uconnect systems may experience a reboot every 45-60 seconds. Our Engineering teams are investigating the cause and working towards a resolution.

Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:

Dodge recalls 27k Darts for bracket that can disrupt transmission module

Dodge is recalling 27,520 examples of the 2013-2015 Dart with dual-clutch gearboxes. The mounting bracket for the transmission control module can affect the part's operation and cause the compacts to suddenly shift into neutral. According to the automaker, 23,688 of them are in the US, 3,376 in Canada, 5 in Mexico, and 451 elsewhere. The National Highway Traffic Safety Administration reports these examples carry build dates between February 24, 2012, and June 16, 2015. There are also no reports of accidents or injuries. Because of the way the bracket is mounted, the part can put too much force on the control module's circuit board and cause it to shift out of gear. The engine and airbags remain operable if this happens. To fix things, dealers will install a redesigned mount and replacement module. Related Video: Statement: Mounting Bracket September 14, 2015 , Auburn Hills, Mich. - FCA US LLC is recalling an estimated 23,688 cars in the U.S. to replace certain control modules and mounting brackets that may contribute to a loss of motive power. The Company is unaware of any related injuries or accidents. An FCA US investigation prompted by a small number of warranty claims discovered a control-module mounting bracket may apply too much force and disrupt the function of a circuit board within the module. This condition, unique to certain cars equipped with dual dry-clutch transmissions (DDCT), may cause the transmission to shift into neutral. However, the engine remains on and the vehicle's air-bags, as well as other safety features, are unaffected. The condition may also be preceded by the illumination of a dashboard warning light. Customers who observe this are urged to contact their dealers. The campaign is limited to certain 2013-2015 Dodge Darts equipped with DDCTs. Additional vehicles will be recalled in Canada (3,376), Mexico (five) and outside the NAFTA region (451). Affected customers will be advised when they may schedule service, which will be performed free of charge. Service will entail installation of a redesigned mounting bracket and replacement of the control module. Customers with additional questions may call the FCA US Customer Information Center at 1-800-853-1403.
