Power steering loss on other Sierra 1500 years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2016, 2017, 2018, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
Power steering loss is the steering wheel suddenly going heavy, usually with a warning on the dash. Nearly six in ten complaints in this group mention a warning light or message, and almost two thirds mention driving or highway speed rather than parking.
What got replaced
Owners who name the part that was replaced mention the steering rack (7 reports) and the EPS motor or module (4 reports).
Recalls and investigations
One recall on the steering system covers the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.
Electric power steering (EPS) assist may be lost momentarily, followed by a sudden return of EPS assist.

Should you keep driving it?
This page can't tell you that. 0 of 44 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
