The 2021 cadillac CT4 edges this one, but it's tight. We're talking 4.6 versus 4.3 on the reliability index. Close enough that the right answer for you might be the other truck — depends what you're using it for and what you can afford to fix when something does go.

Going with the 2021 ram Promaster City? Watch the engine. The 2021 cadillac CT4 has fewer reports in those categories, so you'd be trading one set of weak spots for another.

What goes wrong more often on the 2021 RAM Promaster City?

Which has more recalls?

The 2021 RAM Promaster City has more active recalls (3 vs 0). Total count is less important than severity, though — a vehicle with one critical recall and zero moderate ones is generally riskier than one with five moderate recalls.

Is an extended warranty worth it on either of these?

Both vehicles are out of factory bumper-to-bumper coverage at this point. Combined repair exposure across the top problem categories runs around $3,100 on the higher-risk vehicle. A quality service contract typically costs $1,800–3,500 over 3 years, so a single major failure usually pays for the contract. The math favors warranty coverage on whichever vehicle you choose, especially if you plan to keep it past 100,000 miles.
