Before this visit, the vehicle had no history of drivetrain problems. It had recently completed an approximately 8\u00bd-hour drive from [XXX] to [XXX], followed by three weeks of normal driving, without any binding, vibration, shuddering, abnormal turning characteristics, warning lights, or drivability concerns.  The dealership retained the vehicle for four days for what was represented as a one-day service. On XXX, I was told the vehicle had been road tested and was safe for release. **Immediately after taking delivery**, the vehicle developed severe drivetrain binding, violent shuddering, heavy vibration, and significant resistance during normal turns, creating an immediate safety hazard. I returned directly to the dealership. After initially stating they could not duplicate the condition, the dealership ultimately diagnosed **both rear CV half shafts as failed** and prepared an approximately $4,500 repair estimate.  The dealership later performed a second rear LSD fluid service **without my knowledge or authorization** after concerns were raised about the original service. They initially offered to replace both rear CV half shafts at no cost, but later withdrew that offer and returned the vehicle to me with both rear CV half shafts still broken.  I respectfully request that NHTSA investigate whether improper drivetrain service procedures, incorrect lubricant application, inadequate post-service inspection, or another safety-related condition can cause catastrophic driveline failure immediately following routine maintenance. I am also concerned that the forces sufficient to fracture both rear CV half shafts may have damaged other AWD drivetrain  INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)","products":[{"type":"Vehicle","productYear":"2020","productMake":"GENESIS","productModel":"G70","manufacturer":"Hyundai Motor America"}]}]}
