Brake wear on other Terrain 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: 2014, 2015, 2016, 2017, 2026.

What this problem usually is

Brake reports cover a wide spread of symptoms. Grinding or squealing is common, and so is a pulsing pedal or a shake through the car when stopping. Others describe pads and rotors worn out long before they expected, a brake warning light, or a pedal that goes soft or sinks toward the floor. The most serious ones say the car didn't stop in time.

Recalls and investigations

One recall on the brakes covers the 2019 model year. A recall on the same system isn't always the same failure, so read the defect text.

The rear brake caliper pistons may have an insufficient coating causing gas pockets to form, potentially reducing rear brake performance.

Is this a known problem?

The manufacturer has sent NHTSA 6 service bulletins or notices for the 2019 GMC Terrain 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.

Should you keep driving it?

This page can't tell you that. 1 of 71 reports involved a crash and 3 people were hurt. 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.
