Electricity, for all its benefits, can be a real pain in the backside sometimes. That's especially true for Fiat Chrysler, as it just issued two unrelated recalls for issues involving electricity and wiring.
The larger recall covers 182,743 US-based examples of the 2016 and 2017. The issue comes from the wiring harness. In "certain crash events," as FCA puts it, some wiring may disconnect from the car's impact sensors. The impact sensors help determine when airbags should deploy, so a disconnected sensor could prevent the airbags from deploying correctly.
Thankfully, there are no injuries related to this issue at this time. The dealership will reroute the wiring, which will fix the problem. All affected 2017 models are still in dealers' hands, so the cars will be fixed by the time they are sold to customers. The fix is available now, but customers will be notified by first-class mail like usual.
The second recall affects more niche vehicles, covering some 74,833 examples of the following vehicles: 2007-2013 Ram 2500/3500 pickup, 2007-2013 Ram 3500/4500/5500 chassis cab and 2011-2014 Dodge Charger Pursuit.
In this case, the problem lies within the alternator. The alternator's diode may wear prematurely when operating in more extreme conditions. If that happens, the alternator may short circuit, which could cause either an engine stall or a vehicle fire.
Dealerships will replace the alternator as necessary, which should solve the problem. Owners will be notified and advised when to schedule service. It appears the replacement parts are not yet ready, though.
