Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2020 Chevrolet Blazer that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
This Preliminary Information communication provides information to the technician with additional information on the functionality of Lane Keep Assist.
What owners wrote
“I was driving and steering reduced drive with caution notification and brake assist notification came on and then engine light and the temp gage went to cold and stayed there. My steering stiffened up making it hard to steer. This is a known problem with the Chevy blazers and it had to do with the thermostat needing replaced.”
Filed Jul 10, 2026
“Check engine light on, message saying "steering assist reduced drive with care", engine temperature gauge not moving from C, and AC not working. I have taken it in to be fixed 3x, and they have fixed it 2/3 times but the message has come back again. It is a big issue in 2019/2020 blazers according to my research.”

“Steering assist reduced warning is on all the time. Fan is on overdrive and thermostat needle on cool all the time. Leaking camshaft actuator solenoids”
Filed Aug 1, 2025

Should you keep driving it?
This page can't tell you that. 0 of 35 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.
