reported issues, recalls & what to inspect
This report uses official federal safety records plus VeroRoad’s vehicle × tool evidence. It is a screening tool, not a reliability grade or prediction that your specific car will fail.
31 unique complaint records5 recall campaigns returned0 complaint rows with usable mileage10 local vehicle/tool evidence rows
NHTSA complaints are consumer-submitted allegations, not verified failures. Raw complaint totals are not failure rates because vehicle sales/exposure are not normalized here. A recall is an official safety campaign, but your VIN may or may not be included.

What I would inspect before money changes hands
The highest reported component groups are converted into inspection tasks. They are not diagnoses.
Engine & powertrain
17 owner complaints in the leading component signal intersect this system.
- Cold-start behavior and idle quality
- Acceleration under light and moderate load
- Current, pending and permanent DTCs
- Freeze-frame and fuel/engine live data where available
Brakes & ABS
4 owner complaints in the leading component signal intersect this system.
- ABS/ESC warning lights
- Wheel-speed live data if a warning is present
- Brake pedal feel and parking-brake operation
- Pad/rotor condition and uneven wear
Electrical & 12V system
3 owner complaints in the leading component signal intersect this system.
- 12V resting and charging voltage
- Module communication scan
- Battery age and terminal condition
- Unexpected warning lights or intermittent electrical behavior
Tires & TPMS
3 owner complaints in the leading component signal intersect this system.
- Tire age and matching set
- Uneven wear or sidewall damage
- TPMS warning status
- Correct pressure after a cold soak
ADAS & visibility
2 owner complaints in the leading component signal intersect this system.
- ADAS warning lights
- Camera/radar area damage or windshield replacement history
- Lane/forward-warning operation on a safe road test
- Calibration records after collision, glass or alignment work
SCAN INTEGRITY CHECK
Make it harder for a recently cleared warning light to fool you.
A clean dashboard is not the same as a clean scan. Readiness monitors, pending codes and permanent codes provide useful context during a pre-purchase inspection.
- Run a full-system scan before clearing anything
- Read current, pending and permanent powertrain codes
- Check readiness monitors; multiple “Not Ready” monitors can be consistent with a recently cleared ECU or disconnected battery
- Save freeze-frame data for any stored emissions/powertrain fault
- Scan ABS, SRS, transmission and body modules when the tool supports them
- Check 12V battery / charging condition because low voltage can create misleading module faults
TSBs & MANUFACTURER COMMUNICATIONS
Look beyond recalls.
Manufacturers submit service bulletins, warranty extensions, repair instructions and other communications to NHTSA. These documents can reveal service procedures and known conditions that are not necessarily safety recalls.

SOURCE TRANSPARENCY
Where these signals come from
Federal data are fetched from NHTSA’s public APIs. VeroRoad aggregates the records into screening signals and keeps complaints separate from confirmed recalls.
