What is your Sierra 1500 doing?
Each one opens a sheet built from the owner reports of that problem on the 2015 model year.
Is the 2015 GMC Sierra 1500 reliable?
The 2015 GMC Sierra 1500 has 719 owner complaints on file with NHTSA, 2.4 times the median of 299 for 2015 pickups on this site. Of the 13 Sierra 1500 model years since 2014, it has the most complaints. Complaint counts rise with sales as well as faults, so read what owners report below before deciding.
At a glance
- Next to other model years
- Complaints filed before 2015 aren't in the files this site reads, so the 2015 count runs short and isn't compared with the model years next to it.
- Top problem
- Brake wear leads with 229 of the 719 complaints (32%), ahead of headlights at 83. A quarter of the 168 owners who gave a mileage for brake wear saw it by about 43,000 miles, and half by about 57,000.
- Crash, fire and injury reports
- 33 of the 719 complaints (5%) report a crash, a fire or an injury, a little under the 6% typical of vehicles on this site. Counted separately (one report can carry more than one), 23 reports mention a crash, 9 mention a fire and 11 people were hurt. The most crash reports, 15 of 23, fall under brake wear.
- Recalls behind the top problems
- Brake wear and power steering loss each have a recall on the same system (19V-645 and 19V-761; 18V-586). Headlights has none. A recall on the same system doesn't always cover the failure owners describe, so compare its summary with the complaints.
- When owners filed
- Filings peaked in 2019 at 139 (full calendar years only). In 2025 there were 48. So far in 2026, 27 more have come in. Filings on record start in 2015.
