Electrical System
1,445 of the 4,542 complaints (31%) mention the electrical system. Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.
Fuel System, Gasoline
1,284 of the 4,542 complaints (28%) mention the fuel system. Fuel system problems can cause stalling, hard starts and poor mileage. We test fuel delivery and related sensors to find the real cause. See our no-start diagnostics and check engine light diagnostics pages.
Exterior Lighting
494 of the 4,542 complaints (10%) mention lighting and visibility. Lights, wipers and visibility items are quick to fix and are on every rideshare inspection checklist. We check them as part of our inspection prep. See our rideshare inspection prep page.

Most Common Chevrolet Trailblazer Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the Trailblazer. The most-cited is P2714 (powertrain code), mentioned in 5 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| P2714 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 5 |
| P1467 | Manufacturer-specific powertrain code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 5 |
| P0463 | Fuel level sensor circuit high Failing fuel level sender, which can cause a wrong fuel gauge reading. | 3 |
| P0700 | Transmission control system malfunction The transmission computer stored its own code. A scan of the transmission module shows the real fault. | 3 |
| P0299 | Turbocharger underboost Boost leak, failing turbo or wastegate, or a boost sensor issue. | 2 |
| U0151 | Network code A scan and test is needed to confirm what this code means for your vehicle. | 2 |
A code is a clue, not a diagnosis. The same code can have several causes, so we test before replacing parts. See our check engine light diagnostics, and read whether it is safe to drive with the check engine light on.

Keeping a Chevrolet Trailblazer Reliable in Phoenix
Arizona heat is the hardest test a Chevrolet will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Trailblazer that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for Trailblazer owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Chevrolet Trailblazer, a pre-purchase inspection shows what the paperwork does not.
