Looking at this input, I can see:
- Recalls 3, 4, and 6 all describe the same side airbag wiring harness defect (same physical problem, multiple filings). Group as one issue.
- Recalls 5 and 7 both describe the MAF sensor stalling issue on 2.5L V6 engines. Group as one issue.
- Recall 1: suspension/subframe corrosion causing loss of drive power and wheel-fender contact
- Recall 2: subframe corrosion (salt states, structural)
Recalls 1 and 2 both involve subframe corrosion but in different regions (US states vs Canadian provinces) and different described consequences. Recall 1 mentions loss of drive power and wheel contacting the fender/wheel well. Recall 2 mentions thinning/perforation of subframe steel with no risk description. These are likely the same underlying defect (road salt corrosion of subframe) filed in different jurisdictions. I'll treat them as one issue per grouping rules.
Lead: The subframe corrosion issue (severity 5) is most serious — wheel can contact fender, loss of drive power, crash risk.
Then: side airbag wiring (severity 4), MAF sensor stalling (severity 3).

**The 1999 Hyundai Sonata has 7 recalls, the most serious involving subframe corrosion in high road-salt regions where the steel can thin or perforate, potentially causing loss of drive power
