Common problems with the 2006 Terraza
NHTSA's file holds 54 owner complaints on the 2006 Buick Terraza. Owners named the electrical system most often: 11 complaints, and half of the 9 that list a mileage came after 13,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Electrical System | 11 | 9 | 13,900 |
| Electronic Stability Control (ESC) | 11 | 11 | 113,000 |
| Structure | 11 | 9 | 13,000 |
| Service Brakes, Hydraulic | 8 | 8 | 42,000 |
| Suspension | 8 | 7 | 87,560 |
Of the 54 complaints, 4 report a crash, none reports a fire and 5 report an injury (7 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2006 Terraza
The 48 mileages owners gave run from 12 to 248,747 miles. A quarter are at or under 13,543 miles, half at or under 42,000, three quarters at or under 82,016 and nine in ten at or under 140,000; 8 (17%) came after 100,000 miles, 2 (4%) after 150,000 and 1 (2%) after 200,000.
These mileages say when owners reported a problem, not when a 2006 Terraza 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: 40 of the 48 came at or under 100,000 miles, so they say nothing about how many miles a 2006 Terraza can cover.
| Measure | Value |
|---|---|
| Lowest mileage listed | 12 miles |
| 25th percentile | 13,543 miles |
| Median (50th percentile) | 42,000 miles |
| 75th percentile | 82,016 miles |
| 90th percentile | 140,000 miles |
| Highest mileage listed | 248,747 miles |
| Complaints after 100,000 miles | 8 (17%) |
| Complaints after 150,000 miles | 2 (4%) |
| Complaints after 200,000 miles | 1 (2%) |
Is the 2006 Terraza a good year?
Complaint counts cannot say whether the 2006 is a good or a bad Terraza: they rise with how many were sold and how long they have been on the road. They show how the 2006 compares with the other model years in NHTSA's file.
With 54 complaints, the 2006 ranks 2nd of the 3 Buick Terraza model years from 2005 to 2007 with 10 or more complaints, counting from the most. The most: the 2005 (120). The fewest: the 2007 (33).
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 |
|---|---|---|---|
| 2005 Terraza | 120 | 99 | 43,000 |
| 2006 (this page) | 54 | 48 | 42,000 |
| 2007 Terraza | 33 | 31 | 33,000 |

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 2006 Terraza 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 2006 Terraza.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 6 of the 54 complaints on the 2006 Buick Terraza 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: TERRAZA. 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: TERRAZA.

Each complaint is counted once, by its NHTSA number, with the model year and mileage of its first row; a model year has a page only with 10 or more complaints.
