Common problems with the 2015 Regal
NHTSA's file holds 33 owner complaints on the 2015 Buick Regal. Owners named the engine most often: 9 complaints, and half of the 7 that list a mileage came after 53,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Engine | 9 | 7 | 54,000 |
| Exterior Lighting | 8 | 4 | Under 5 mileages |
| Electrical System | 5 | 3 | Under 5 mileages |
| Fuel/propulsion System | 4 | 3 | Under 5 mileages |
| Air Bags | 3 | 1 | Under 5 mileages |
Of the 33 complaints, 1 reports a crash, 1 reports a fire and 2 report an injury (3 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2015 Regal
The 22 mileages owners gave run from 2 to 111,000 miles. A quarter are at or under 12,000 miles, half at or under 25,000, three quarters at or under 54,000 and nine in ten at or under 102,000; 3 (14%) came after 100,000 miles, none after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2015 Regal wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Most of these reports came early in the vehicle's life: 19 of the 22 came at or under 100,000 miles, so they say nothing about how many miles a 2015 Regal can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 2 miles |
| 25th percentile | 12,000 miles |
| Median (50th percentile) | 25,000 miles |
| 75th percentile | 54,000 miles |
| 90th percentile | 102,000 miles |
| Highest mileage listed | 111,000 miles |
| Complaints after 100,000 miles | 3 (14%) |
| Complaints after 150,000 miles | none |
| Complaints after 200,000 miles | none |

Is the 2015 Regal a good year?
Complaint counts cannot say whether the 2015 is a good or a bad Regal: they rise with how many were sold and how long they have been on the road. They show how the 2015 compares with the other model years in NHTSA's file.
With 33 complaints, the 2015 ranks 6th of the 9 Buick Regal model years from 2011 to 2019 with 10 or more complaints, counting from the most. The most: the 2011 (280). The fewest: the 2018 (19).
NHTSA files the Buick Regal name for 1986–2004 and 2011–2019. A gap of three or more model years means the name covers different vehicles, so the 2015 is compared only with the 2011–2019 model years.
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2011 Regal | 280 | 205 | 66,900 |
| 2012 Regal | 92 | 63 | 59,527 |
| 2013 Regal | 91 | 62 | 58,000 |
| 2014 Regal | 38 | 26 | 47,000 |
| 2015 (this page) | 33 | 22 | 25,000 |
| 2016 Regal | 41 | 21 | 27,000 |
| 2017 Regal | 20 | 14 | 70,509 |
| 2018 Regal | 19 | 11 | 22,000 |
| 2019 Regal | 20 | 9 | Under 10 mileages |
2015 Buick Regal recalls
NHTSA's recall files of November 11, 2026 list no campaign for the 2015 model year under the name REGAL. Recalls can be filed under another name (a trim, a body or a series name), so a recall may still exist for the 2015 Buick Regal: check the VIN with NHTSA's free recall lookup.
What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2015 Regal lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2015 Regal.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 11 of the 33 complaints on the 2015 Buick Regal give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA name counted: REGAL. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only this one.
- Recall-file name matched: REGAL.
