Fires, deaths continue after Jeep fuel tank recall

As Kayla White slowed her SUV behind two other cars to exit a suburban Detroit freeway on Veterans Day, it was rammed from behind by a Cadillac STS. Her red 2003 Jeep Liberty bounced off a Nissan in front of it, rolled onto its side and exploded in flames. Other drivers ran to help but were forced back by the heat. Firefighters arrived in just three minutes but were too late. White, a 23-year-old restaurant hostess who was eight months pregnant, died of burns and smoke inhalation. White is one of more than 70 people killed in fires involving older Jeeps with plastic fuel tanks mounted behind the rear axle. Fiat Chrysler, which makes Jeeps, recalled 1.56 million of them in June 2013 under pressure from US safety regulators. But only 12 percent of the SUVs have been repaired in the 18 months since the recall, a much slower pace than usual. And White's Jeep was not among those fixed. Last week, prosecutors charged the Cadillac driver with committing a moving violation that caused a death. But safety advocates and the lawyer for White's family say the blame belongs as much, if not more, on Chrysler and an auto-industry safety system that moves too slowly to prevent tragedy. The rear-mounted tanks have little structure to protect them if struck from behind, making them susceptible to punctures and fires. Moving the gas tank in front of the axle would be expensive and difficult. So Chrysler's remedy involved installing trailer hitches on the rear of the Jeeps as an extra layer of protection. Government testing showed the hitches protected the tanks in crashes up to 40 mph when stationary Jeeps were hit from behind. But at higher speeds, they wouldn't help. White tried to get the repair done a few weeks before her death but was told by a Jeep dealer that parts weren't available, according to Gerald Thurswell, her family's lawyer. He wouldn't identify the dealership, and his contention could not be independently verified by The Associated Press. Thurswell contends the gas tank ruptured, spilling fuel that touched off the fire. A Chrysler spokesman expressed sympathy to White's family but said the company had no written proof that she asked a dealer about the recall. Two crash reconstruction experts interviewed by the AP say gas wouldn't have spilled from White's Jeep if the tank had been mounted in front of the rear axle. Both say a hitch might have prevented the tank from being damaged, but because both vehicles were in motion, neither expert could say for sure.

Jeep Renegade sales being held due to powertrain issue [UPDATE]

UPDATE: An unnamed FCA US source has clarified to Automotive News that while there is a software issue, it does not concern the transmission. The Jeep Renegade appears to be facing early software problems that are similar to the ones at the introduction of the Cherokee a few years ago. The issue is keeping the brand's latest compact crossover away from dealers until the situation can be resolved. The fault reportedly deals with the software controlling the Renegade's nine-speed automatic transmission. FCA CEO Sergio Marchionne briefly talked about what was happening in an interview with Automotive News. "I'm having a very bad engineering day," he said. "It's a combination of attributes of that vehicle that is making my life horrible." The company boss predicted at the longest it could take until mid-June to fix things. Through April, Jeep has sold 5,157 Renegades, including 4,214 of them in that month alone. Autoblog reached out to an FCA US spokesperson to learn more about the software problem, but the company had no comment. Getting the software right to control the nine-speed automatic plagued development of the Cherokee. The issues delayed the model's launch in 2013, and the company was still releasing improvements for some vehicles this year.

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.
