Hello! Recently, I got into a mid-damage accident and gave the car for repair. The overall repair was not done very well, but the biggest problem that makes driving impossible is the greasy and oily interior. After 1-2 hours of driving, I start to feel bad, my head hurts and I feel dizzy and sick. The coolant level is normal and does not visually drop. What can evaporate into the cabin and how to deal with it? Maybe there’s a leak somewhere? Car is 2022 Hyundai Sonata Hybrid. Thanks in advance for your answers!

 

Since not too many shops are qualified to handle Hybrid repairs, I would have a dealership check it out thoroughly,
Could be battery fumes, leaking A/C system ,exhaust fumes , we don't know and it is not wise to diagnose over the net without actually checking in person.
This would be considered a safety concern and should be checked ASAP.
