2003 CHEVROLET SUBURBAN
This model year
What the record shows
The 2003 Chevrolet Suburban is the 27th model year of a nameplate NHTSA records from 1977 to 2026.
The federal record holds 301 owner complaints and 706 service bulletins for it.
Counts are reports, not rates. A complaint is something an owner chose to file; it is unverified and unadjusted for how many of these cars were sold, so the useful comparison is against other model years of the same car. Recalls and investigations carry more weight because a manufacturer or regulator acted on them.
Reading this report
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
