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.
What we checked
Partly reconciled against public records, 2026-09-25
NHTSA holds 182 owner complaints for the 2018 Chevrolet Colorado ZR2, and 1 recall campaign.
A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 43% of them are about one thing — the transmission and drivetrain. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.
One recall campaign covers this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.
Not written up yet: electrics and electronics (35 complaints). That group is in the public record and is not covered by the issues below. Treat it as something to ask about, not as absent.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
