About the 2021 Cadillac CT4

With an overall Carivo score of 7.4/10, the 2021 Cadillac CT4 earns a Good rating among the sedans we've scored. Its strongest dimension is Safety at 8.0/10, while Reliability at 6.9/10 is where it trails the competition most noticeably. It's a capable but unexceptional sedan — stronger alternatives exist if you're willing to shop the segment carefully.

Reliability and safety are the two dimensions that matter most for long-term ownership costs. We rate reliability at 6.9/10 — below the segment average in our scoring. Budget for potentially higher maintenance costs and check the recall record below before buying. On safety it earns 8.0/10: respectable, if not class-leading — several competitors bundle more driver-assist tech as standard. Check your trim's official ratings at nhtsa.gov.

Performance lands mid-pack at 7.3/10: enough power and composure for everyday needs, without the dynamics that distinguish the segment's driver-focused options. Technology comes in at 7.7/10 — functional and modern, with wireless connectivity and core ADAS features, though some competitors pack more standard tech at this price point.

Priced from $32,022–$43,209, 26 MPG, seating 5, the Cadillac CT4 sits in the mid-market bracket of the sedan segment. Value lands at 7.2/10 — you get what you pay for, no more and no less, with a few rivals offering slightly better per-dollar returns. At 5 years old, it's worth checking whether a newer generation or refresh has addressed any weaker dimensions — compare it to the current model year before buying.

Bottom line: There's a case for the 2021 Cadillac CT4, but it needs the right buyer. Its reliability scores trail the class, and several higher-rated rivals sell for similar money — comparison-shop before committing.
