NHTSA investigating 630k Jeep Wranglers for possible airbag fault

The National Highway Traffic Safety Administration is opening a preliminary evaluation into a possible wiring problem on some 2007-2012 Jeep Wrangler models that could affect airbag deployment. The government agency has 221 complaints alleging that the airbag warning light is illuminating, and that could indicate that the safety devices might not deploy in a crash. If a recall is necessary, an estimated 630,000 vehicles could be affected. According to the documents from NHTSA (as a PDF here), a "faulty clockspring assembly in the driver side airbag electrical circuit" could be the culprit. Also, some of the affected Wranglers are showing a fault code that indicates the safety device wouldn't deploy in an accident. However at this time, there are no reports of injuries related to this potential problem. NHTSA's preliminary evaluations are simply meant to investigate and don't necessarily lead to a recall. This isn't the first time for a potential problem like this on the Wrangler, though. A clockspring issue already led to a safety campaign for 2008-2012 right-hand drive Wranglers and an extended warranty for 2007 left-hand drive examples.

Several complaints cite the following diagnostic trouble code (DTC): Code B1B02 Open Squib to driver's air bag. This DTC would indicate a no-fire condition (disablement) for the driver air bag. ODI investigated the RHD (right hand drive) Wrangler for a clockspring issue under PE11-019 which led to NHTSA Recall 11V258 on model year (MY) 2008-2012 RHD Wranglers as well as an extended warranty campaign on MY 2007 LHD Wrangler vehicles. This investigation covers the MY07-12 LHD (left hand drive) Wranglers.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

2018 Jeep Wrangler will have an aluminum hood and doors, leaked memo says

Earlier this year, FCA CEO Sergio Marchionne revealed that 2018 Jeep Wrangler would feature a heavy dose of aluminum, though he didn't specify how. Now, JL Wrangler Forums says the Wrangler will use the material for the hood and the doors, citing an internal bulletin from aluminum supplier Alcoa. According to the forum, the company says the next-gen Wrangler will utilize Aloca's C6A1 (an internal name) high form alloy. The SUV will also get 6022 and A951 from Alcoa that will be used on the SUV's front and rear doors, as well as for the hood. Alcoa's C6A1 is the company's new high form alloy, while its 6022 alloy sheet can be found on things like a car's hood, door, or closure panels. Alcoa's A951 is the company's pre-treatment aluminum sheet bonding technology that it uses on automobiles. "A team in the Farmington Hills (Michigan, USA) Aerospace and Automotive Products group is leading a new profitable growth opportunity with the 2018 Jeep Wrangler program. The next generation Jeep becomes the first to utilize our C6A1 high form alloy; we are currently the only supplier of this high form product. Alcoa will also supply 6022 and A951, including front and rear door inners, hood outer and inner." As Marchionne pointed out earlier this year, the 2018 Wrangler won't be made entirely out of aluminum. So Alcoa's contribution to the upcoming SUV's doors and hood could be the only components that use the lightweight metal – or Jeep could be using another aluminum supplier for other parts. Large changes lie ahead for the 2018 Wrangler, which include a pickup version, new engines, and aluminum. But we do know that the next Wrangler is that it will be built in Toledo, OH, as FCA announced plans to spend $1.05 billion to retool the Wrangler factory, while also adding another site in Illinois earlier this year.
