The company continued to receive failure reports, even after revising its design.

Fiat Chrysler Automobiles has issued another recall related to electronic problems with its 2015-2016 Jeep Cherokee.The company in June recalled 164,000 units after experiencing power liftgate failure due to water intrusion around the control module. In some cases, the defect could even lead to short-circuit fires.

Ahead of the formal recall, FCA revised its engineering design and began building Cherokees with an additional water shield and plug to help prevent water from entering the control module. The company later received two failure reports involving vehicles built with the improved components.

Another investigation found that water had entered the module from a different route than FCA had considered in its initial recall. Engineers went back to the drawing board and devised a new water shield, now fully encasing the failure-prone control modules to prevent water intrusion from any direction.

The company claims to be unaware of any accidents or injuries related to the defect, which affects nearly 33,000 vehicles. Service technicians have been instructed to remove the old mastic shield and install the new full water shield, replacing any corroded control modules if necessary.

A separate Cherokee recall traced vehicle fires to a manufacturing screwup involving the air-conditioning hose routing near the exhaust manifold heat shield.
