Common problems with the 2018 Suburban
NHTSA's file holds 84 owner complaints on the 2018 Chevrolet Suburban. Owners named the engine most often: 19 complaints, and half of the 5 that list a mileage came after 87,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Engine | 19 | 5 | 88,000 |
| Power Train | 19 | 4 | Under 5 mileages |
| Electrical System | 17 | 7 | 68,000 |
| Service Brakes | 13 | 2 | Under 5 mileages |
| Steering | 8 | 0 | Under 5 mileages |
Of the 84 complaints, 3 report a crash, none reports a fire and 2 report an injury (4 people reported injured). These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2018 Suburban
The 27 mileages owners gave run from 60 to 208,257 miles. A quarter are at or under 10,000 miles, half at or under 42,000, three quarters at or under 88,000 and nine in ten at or under 129,000; 6 (22%) came after 100,000 miles, 1 (4%) after 150,000 and 1 (4%) after 200,000.
These mileages say when owners reported a problem, not when a 2018 Suburban 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: 21 of the 27 came at or under 100,000 miles, so they say nothing about how many miles a 2018 Suburban can cover.
Complaint mileage also follows a model year's age: the 2018 has had less time to cover miles than older years, so its figures will rise as it ages.
| Measure | Value |
|---|---|
| Lowest mileage listed | 60 miles |
| 25th percentile | 10,000 miles |
| Median (50th percentile) | 42,000 miles |
| 75th percentile | 88,000 miles |
| 90th percentile | 129,000 miles |
| Highest mileage listed | 208,257 miles |
| Complaints after 100,000 miles | 6 (22%) |
| Complaints after 150,000 miles | 1 (4%) |
| Complaints after 200,000 miles | 1 (4%) |

Is the 2018 Suburban a good year?
Complaint counts cannot say whether the 2018 is a good or a bad Suburban: they rise with how many were sold and how long they have been on the road. They show how the 2018 compares with the other model years in NHTSA's file.
With 84 complaints, the 2018 ranks 28th of the 40 Chevrolet Suburban model years from 1987 to 2026 with 10 or more complaints, counting from the most. The most: the 1994 (872). The fewest: the 1987 (18).
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.

|---|---|---|---|
| 1987 Suburban | 18 | 0 | Under 10 mileages |

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 2018 Suburban 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 2018 Suburban.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 57 of the 84 complaints on the 2018 Chevrolet Suburban give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA names counted: SUBURBAN, SUBURBAN 1500 and SUBURBAN 2500. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
- Recall-file names matched: SUBURBAN, SUBURBAN 1500 and SUBURBAN 2500.
