U0428 on Chevrolet by model: symptoms, diagnosis and fix
GM recalled 2014 Silverado 1500 (NHTSA 17V414, ~690,685 units) and 2015 Silverado/Tahoe/Suburban (over 1 million units) for a temporary loss — and sudden return — of electric power steering assist, especially during low-speed turns. The EPS draws a high-energy load in low-speed maneuvers; when system voltage drops below ~8.8V for more than a second, the module disables assist until voltage recovers, with steering then snapping back to assisted. The sudden change in steering effort can cause loss of control. The remedy is an EPS module software update that reduces the steering system's energy demand. High search demand and a clear safety-recall pedigree.
Common Symptoms
- Steering suddenly becomes very heavy, then snaps back to power-assisted
- Loss of power steering during low-speed turns / parking
- 'Power Steering' warning or message on the DIC
- Hard steering after start in cold weather
How to Fix
Check VIN against NHTSA recalls 17V414 (2014) and the 2015 EPS campaign and have the dealer flash the updated EPS module software free of charge — this 'greatly reduces' the steering system's energy demand and prevents the dropout. If assist is being lost, also have the battery, alternator and charging-system voltage and grounds checked, since marginal charging voltage triggers the fault.

Frequently asked questions
What does U0428 mean on a Chevrolet?
U0428 stands for "Lost Communication with Steering Angle Sensor Module." U0428 is a network communication code meaning a control module (commonly the ABS/stability control or steering control module) has lost communication with the steering angle sensor module over the vehicle's data bus. The steering angle sensor tells the stability-control and electric power-steering systems exactly how far and how fast the steering wheel is being turned. When that data stops arriving, systems like ABS, traction control, and electronic stability control can disable themselves and turn on warning lights. This is typically a wiring, connector, or module/bus problem rather than steering damage. On Chevrolet it is documented across 1 model: Silverado.
What are the most common causes of U0428?
The most common causes of U0428 are: Wiring or connector fault between the sensor and the bus, Failed steering angle sensor module, Corroded or damaged clockspring/spiral cable connector, CAN bus wiring damage, short, or open circuit, Loss of power or ground to the steering angle sensor, Faulty ABS or steering control module, Software issue or sensor not calibrated after service. The specific cause varies by vehicle.
How much does it cost to fix U0428 on a Chevrolet?
Repair costs vary widely with the root cause and Chevrolet model; each issue on this page carries its own estimate where one is published.
