2016 Chevrolet Colorado Z71 Diesel Replace 7: Wonky Switches and Tiny Points


Our 2016 Chevrolet Colorado Z/71 Duramax had a little bit of a character disaster when it first joined our fleet. As a few of chances are you’ll bear in mind, our Colorado had two small points when it was first delivered: the change financial institution on the middle console didn’t reliably work, and the driving force data middle display screen on the instrument cluster proudly displayed the GMC brand on startup as an alternative of the proper Chevrolet bowtie.

I already coated the brand switcheroo repair again in replace one, so let’s tackle the wonky switches and the handful of different small points that our Chevy Colorado has suffered from over the previous yr.

Busted Buttons

Each Chevy Colorado comes with 5 rocker switches on the decrease portion of the middle stack, every actuated by taping down on them. These switches management, from left-to-right, the exhaust brake/tow/haul mode, traction management, the hazards, the cargo mild, and hill first rate management.

All 5 of the switches had a few half-inch of play in them, and worse nonetheless, the traction management change solely labored intermittently and provided that you pushed down actually onerous on the intense left fringe of the change.

Our native Chevy seller at first thought this might be a fast hour-long repair earlier than a tech realized that they’d have to drag aside the dashboard to switch all 5 switches. In the future and a Chevy Spark-loaner later, and our Colorado was returned to us, lastly in the identical form it ought to’ve been in when it left the manufacturing unit.

Honk Honk

This one was a primary—not lengthy into its stick with us, the Colorado’s horn shorted out and stopped working. Affiliate editor Scott Evans took our Chevy off-roading again in replace quantity two and made fairly the bow wave by a water crossing, shorting out the horn within the course of. The horn’s mounting place close to the grille doesn’t actually assist issues, however it was hardly our Colorado’s fault. Nonetheless, the horn was changed beneath guarantee and hasn’t given us any points within the loads of off-roading the truck has seen since.

Steering Squeaks

I don’t learn about you, however creaks and rattles in brand-new vehicles drive me mad. Round 4 or 5 months into our mortgage, our Colorado’s steering column began to make a squeaky-binding sort noise, which was particularly noticeable at metropolis speeds in 90-degree turns.

It was fairly onerous to determine the place the sound was coming from (for each the Chevy seller and me). At first we thought it was the airbag cowl on the steering wheel rubbing. The airbag cowl’s mounting screws had been lubed up, however the sound persevered.

Subsequent, the Chevy seller tried lubing the bolts that mount the steering wheel to the steering shaft. Higher, however the sound was nonetheless there.

Lastly, the seller seen a service bulletin calling for the alternative of the decrease portion of the steering rack, which might remove binding and noises from the steering shaft. The service adviser despatched me away in a Chevy Cruze and instructed me he’d replace me tomorrow on the repair, however he talked about it may take a pair days.

The following afternoon the service advisor known as me. I anticipated an replace, however obtained higher information—the Colorado was cured. And certainly it was; the Colorado’s steering rack has been squeak-free since.

Squeaky leaf springs

After a trouble-free third-quarter, the rear leaf springs began to squeak and chirp as they rubbed towards one another on bumps. The noises weren’t obvious with the home windows up, however they might simply be heard at metropolis speeds with the home windows down.

After a fast lube and grease by the seller, the squeaks had been gone.

Climate stripping

After practically 30,000 miles, a lot of which has been off-road within the scorching, dusty SoCal desert, I’d say we’re fairly fortunate that the one casualty is a few rubber climate stripping, simply above the rocker panel on the right-rear passenger door, that’s beginning to come off. The seller resecured the climate stripping the identical morning it was greasing the rear leaf springs, and the truck was good as new, as soon as once more.
