Gear shifters in some Fiat Chrysler models are too confusing, says NHTSA

The National Highway Traffic Safety Administration hasn't forced a recall, but found more than 100 crashes and over a dozen injuries related to the problem
DETROIT—Electronic gear shifters on some newer Fiat Chrysler SUVs and cars are so confusing that drivers have exited the vehicles with the engines running and while they are still in gear, causing crashes and some serious injuries, U.S. safety investigators have determined.
The National Highway Traffic Safety Administration, in documents posted during the weekend, has doubled the number of vehicles involved in an investigation of the problem, but it stopped short of seeking a recall. The agency found more than 100 crashes and over a dozen injuries, mostly in newer Jeep Grand Cherokees.
Agency tests found that operating the shifter “is not intuitive and provides poor tactile and visual feedback to the driver, increasing the potential for unintended gear selection,” investigators wrote in the documents. They upgraded the probe to an engineering analysis, which is a step closer to a recall.
The investigation could determine just how much automakers will be able to change the way cars operate when they introduce new technology, and how far they can stray from conventional ways of operating vehicles that drivers are accustomed to.
The probe now covers more than 856,000 vehicles including the popular Jeep Grand Cherokee SUV from the 2014 and 2015 model years and the 2012 through 2014 Dodge Charger and Chrysler 300 sedans with 3.6-litre V6 engines.
In the vehicles, drivers pull the shift lever forward or backward to select gears and the shifter doesn’t move along a track like it does in most cars.
The cars and SUVs sound a chime issue a dashboard warning message if the driver’s door is opened while the vehicles are not in Park. But the gearshift does not have notches that match up with the gear you want to shift into and moves back to a centred position after the driver picks a gear. Investigators found that the push-button start-stop feature doesn’t let the engine shut off if the vehicles aren’t in park, increasing the risk of the vehicles rolling away after drivers have exited.
“This function does not protect drivers who intentionally leave the engine running or drivers who do not recognize that the engine continues to run after an attempted shut-off,” investigators wrote.
Cars rolling off unintentionally can injure the driver or pedestrians in the path of the vehicles, the agency said. Thus far, the investigation has found 314 complaints, 121 crashes and 30 injuries. Three drivers reported fractured pelvic bones, while four others needed to be hospitalized with a ruptured bladder, fractured kneecap, broken ribs, and severe leg trauma, according to the documents.
Fiat Chrysler says it is co-operating in the probe. The company changed the shifters so they function more like people are used to in the 2016 Grand Cherokee and 2015 Chargers and 300 sedans, but FCA said it did so to increase customer satisfaction and not because of safety concerns.
