UNKNOWN OR OTHER,ENGINEI am reporting a repeated safety-related defect involving exhaust intrusion into the cabin of my 2022 Volkswagen Taos. The vehicle experienced loss of power, coolant loss, and engine warning indicators, and was serviced twice by Volkswagen Southtowne in Sandy, Utah. First Incident – Vehicle Returned as “Safe to Drive” During the first repair visit, the dealer diagnosed issues involving the manifold/exhaust area, head gasket, coolant system, and catalytic converter. After keeping the vehicle for an extended period, the dealership informed me the vehicle was “safe to drive,” although the repair was not fully completed. I relied on this representation. After the vehicle was returned to me, I began experiencing significant physical symptoms only while driving the vehicle, including nausea, dizziness, and vomiting. These symptoms occurred repeatedly during operation and would subside after leaving the vehicle. At the time, I did not understand that these symptoms were caused by exhaust entering the cabin. Second Incident – Defect Confirmed and Additional Repairs Performed Weeks later, the symptoms persisted and I returned the vehicle to the same dealership. At this second visit, the dealer reported coolant leakage and additional gasket failures. They removed the cylinder head, replaced gaskets, and performed additional exhaust-related repairs. I was provided a loaner vehicle during this extended repair. After this second repair, the symptoms while driving stopped. Safety Concern Based on the timing of symptoms, the repair records, and the resolution following the second repair, I believe that exhaust gases were entering the cabin of the vehicle during normal operation for an extended period. This created a significant safety hazard. I was repeatedly assured the vehicle was “safe to drive” when it was not. I unknowingly operated the vehicle while being exposed to exhaust fumes for several months. The condition caused physical illness, impaired my ability.
