How to read this file. Complaint records are unverified owner submissions to the federal safety agency. Counts are raw, not adjusted for sales volume or vehicle age. Recall campaigns apply to the model; only a VIN check shows whether this car is affected or repaired. Parts shown are named by an editorial note or listed as a search directory; none is a diagnosis. Full methodology.

Federal defect investigations
Formal investigations opened by the federal safety agency into this vehicle. An investigation is the step between a complaint pattern and a recall; not every one results in one.

Recall campaigns
Safety-recall remedies are normally provided at no charge. Under US federal law the mandatory free remedy applies when the vehicle was no more than 15 years old at the time the defect was determined; manufacturers often cover older vehicles voluntarily. Canadian rules differ. Confirm eligibility with the manufacturer using the VIN. Each campaign number links to the federal record.

Transport Canada recalls
Recalls issued under Canadian law for this model year, from Transport Canada's Vehicle Recalls Database. Matched by model name, so a Canadian-market variant may appear here that was sold under another name in the US. Units are Canadian vehicles affected.
| Recall | System | Units (CA) | Summary |
|---|---|---|---|
| 2025356 2025-06-27 | Engine | 37,836 | Issue: On certain vehicles, the engine may not have been manufactured properly. As a result, the engine could make abnormal noises and a warning light may turn on. |

Service bulletins and warranty extensions
Manufacturer communications to dealers on file with the federal agency: repair instructions, service campaigns, and warranty extensions. A warranty extension means the manufacturer may pay for a repair the recall table does not cover.

Before you buy this vehicle
A test-drive checklist generated from this vehicle's own complaint and recall record.
- Cold-start it yourself and listen for the first thirty seconds.Knocking, ticking that fades as it warms, or blue or white smoke on startup are the sounds of this vehicle's engine cluster. Check the oil level and the coolant color, and ask whether the engine or its head gaskets have ever been out.
- Try the camera, sensors, and any driver-assist features in a parking lot.A blank or frozen backup camera image and phantom sensor alerts are this vehicle's driver-assistance complaints.
- Sit in it with the engine off and test everything that has a switch.Windows, locks, lights, the cluster, the radio. Electrical faults are this vehicle's story and the hardest to see on a drive: an intermittent no-start waits for the second week of ownership. Ask for the battery's age and whether any control module has been replaced.
- Run the VIN against open recalls before you negotiate.This vehicle has 3 recall campaigns on file. An open recall needs VIN-specific confirmation. Many are quick, no-charge fixes and worth negotiating over; an unresolved do-not-drive advisory, or a remedy the manufacturer has not yet made available, should stop the purchase until it is resolved.
- Ask for the service history in writing, then read it against this page.The complaint families above are where owners of this vehicle report trouble. Repairs in exactly those systems are evidence the car had the problem; no such repairs could mean it never developed it, or that it was never fixed. The test-drive items above are how you tell those apart.
Parts search directory
The generic parts list for this vehicle has its own page: a search launcher for every system, filtered by fuel type and era but not by engine, trim, or brake type. It is not a diagnosis and not a fitment guarantee.
