NHTSA closes investigation into Jeep Liberty fires

The investigation that the National Highway Traffic Safety Administration opened into the Jeep Liberty in October 2013 has been closed. NHTSA received two (!) complaints about fires starting in the driver's door, thought to be caused by the master power window switch. The initial estimate was that 80,000 Libertys could be roped into a possible recall, but according to a report in the Detroit News the agency examined records for 425,000 Chrysler products that used the same window switch, including the Dodge Nitro and Chrysler Town & Country minivan.
After canvassing 265 warranty claims related to the master switches, NHTSA concluded that the rate of fires compared to the "large population of vehicles" was rather low, and that there was no trend pattern behind the few issues it did find. Perhaps with that, and the closure of the trailer hitch investigation, the Liberty can finally rest in peace.

Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.

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.
