No Cadillac XT4 model year in 2021–2021 falls into the flagged band. The weakest are 2021, and even those sit close to this model’s own median.

P — provisional. These years have not completed 60 months on the road, so their totals are incomplete and they are excluded from the verdict.
The component groups most often named, with one representative report. These are unverified — allegations, not findings.

Complaint records show when problems get reported, not how long a car survives. Where owners gave an odometer reading, faults on the 2021 were reported at a median of 34,536 miles. Treat that as the point problems start being noticed, not a lifespan.
Answered directly from this model’s record.
Every model year is scored over an identical window: complaints filed with NHTSA during the first 60 months after that model year went on sale. Without this, older cars look worse purely because they have had longer to accumulate reports.
Limitations. Complaints are unverified reports submitted voluntarily by owners; they are allegations, not findings, and reporting rates vary between models. Model years with fewer than 60 months on the road are marked provisional and excluded from verdicts. Cross-model comparison is withheld pending production-volume data.
