To determine if there's any recall *specific to your vehicle's VIN*, and to report a problem, you should do the following:
1. Check the NHTSA Website: Go to the National Highway Traffic Safety Administration (NHTSA) website (nhtsa.gov). Enter your vehicle's 17-digit Vehicle Identification Number (VIN) to see if any recalls have been issued for your specific Trailblazer. This is the most reliable way to check for recalls.
2. Contact General Motors (GM): If the NHTSA website doesn't show a recall, contact General Motors directly. Their customer service line can check their internal records for any potential issues or service bulletins that might address your problem. You can find their customer service number on their website.
3. Contact your local Chevrolet dealership: They can also assist you in determining if there's a recall or other warranty coverage for the issue. They can also diagnose the problem and provide a repair quote if needed.
It's important to note that even if there's no recall, if the problem is due to a manufacturing defect and you are within the applicable warranty period (if any), GM may still be responsible for repairs.
Keep records of all communication with GM and the dealership. This will be helpful if you need to pursue the issue further.
