2018 Chevrolet Colorado ZR2 — Should You Buy One?

Typical asking price: $26,000–$36,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

A genuinely serious off-road midsize — the ZR2's front and rear locking diffs, trick Multimatic DSSV dampers, and wider track make it a Raptor-lite for the trail. That capability means many were wheeled hard, so inspect closely. Verify the 8-speed fluid service and, on diesels, emissions upkeep. A clean, un-abused ZR2 is a hugely capable and desirable truck that holds value well.

Known Issues for the 2018 Chevrolet Colorado ZR2

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

Off-road abuseHigh — wallet impact

ZR2s get wheeled hard; inspect skid plates, underbody, dampers, and suspension for damage, and check for prior repairs.

Low-speed shudder tied to fluid; a flush/update addresses it. Test-drive around 30-50 mph.

DSSV damper wear/costMedium

The Multimatic dampers are excellent but pricey to replace if worn or damaged.

Repair cost range: $400-$1,500

The 2.8L Duramax needs emissions maintenance; verify history.

Repair cost range: $300-$2,000 if neglected
