While at the dealership service center, the "service electronic power steering" warning light illuminated on the dash and when driven the steering wheel began snapping back, making driving very difficult. The garage informed us that the van is considered unsafe/undriveable until fixed due to the high risk of causing an accident. Upon inspection by the service center, they stated that the steering pump was filled with water from an unknown source and that the harnesses were completely corroded. The wiring/connectors were also completely corroded and appeared to be causing the issues with steering.

Vehicle wheel would suddenly jerk when driving. Video of steering wheel doing this was taken while parked. The suddenness of this created immediate dangers to the driver and any around due to the unpredictability of the steering. Vehicle was brought to a dealer/service center where they diagnosed a corroded wire harness that required the entire steering rack to be replaced. There were no warnings or dash lights on. Vehicle is still at the service center four weeks later because the wire harness is unavailable and the vehicle cannot be safely driven.

Sometimes while driving I experienced my powered steering cut out while taking a ramp on/off of the highway, and sometimes when i was trying to park and back up into a parking space while steering at the same time. When the power steering cut out I got lights for "Service Power Steering", "Service ESC", and "Service Hill Assist" all at the same time, and once i got a power steering light. I looked up the issue and found that there is an active preliminary investigation going on for the same issue on the same vehicle, the investigation coded PE26002. Once I handed the vehicle over to the dealer, they found that the power steering had an open circuit on the steering gear. Once they took the connector off they found that the connector was corroded and the wires were burned on the steering gear and main harness side. I had to have them replace both the steering rack, and the main harness.

Steering Rack and Pinion failure due to corroded electrical connection plug. This occurred in april, 2025, when the van had less than 15,000 miles on it. Took the van to Blue Ridge Chrysler Dodge dealership in Abingdon Va .for Warranty repair. Plug was taken off another vehicle to put on mine aaaand dielectric grease added to hopefully keep the replacement plug from corroding too. Location of plug makes it susceptible to water infiltration, a definite design flaw that is likely to cause trouble again in the future.

Incident

Jul 9, 2026

While driving, a “Service ESC” warning message appeared and the vehicle suddenly lost power steering assist, causing the steering to become extremely difficult and creating a serious safety risk while the vehicle was in motion. The vehicle was taken to a service center, where technicians found multiple loss-of-communication codes involving the electronic power steering system. Further inspection found the main electronic power steering connector full of water and corroded. The technician documented that water intrusion caused excessive damage to the electronic power steering terminals at the rack-and-pinion assembly. The water intrusion appears consistent with a failure or inadequacy of the sealing intended to protect the electronic power steering connection from moisture. Due to the extent of the corrosion and damage, the affected wiring harnesses and rack-and-pinion assembly had to be replaced, followed by a wheel alignment. This failure resulted in a sudden loss of power steering assist while the vehicle was being driven.
