A steering wheel that locks up while driving your 2020 Dodge Charger represents a serious safety issue requiring immediate attention. True lock-up—where the wheel cannot be turned at all—creates a life-threatening situation distinct from heavy steering due to power assist loss.
Distinguishing Lock-Up from Heavy Steering
Complete steering lock while driving (the wheel won't turn at all) is different from loss of power assist (the wheel turns but requires much more effort). True lock-up is rare and extremely dangerous. Very heavy steering from EPS failure is concerning but manageable.
Potential Causes of Lock-Up
Complete steering lock while driving could result from mechanical failure in the steering column, severe internal steering gear failure, or—in extremely rare cases—catastrophic EPS motor seizure. These conditions are uncommon but serious.
Ignition and Steering Column Lock
The steering column lock is designed to engage only when the key is removed. Malfunction of this system could potentially cause unexpected lock engagement. This is a known issue in some vehicles and represents a safety defect.
EPS Motor Seizure
An EPS motor that seizes rather than simply failing to assist would create very heavy steering, potentially feeling like lock-up. True motor seizure is rare but would make steering extremely difficult rather than completely impossible.
Immediate Response
If steering locks while driving, apply brakes progressively while trying to maintain vehicle direction as best possible. Activate hazard lights and aim for the safest available area. Once stopped, do not attempt to drive until the issue is diagnosed and repaired.
Code C1001 and EPS System
Code C1001 relates to EPS system faults. This code captures information about EPS malfunctions but may not specifically indicate mechanical lock conditions. Thorough physical and electronic diagnosis is needed.
