NHTSA Complaint #11590554 — 2017 HYUNDAI SONATA HYBRID

2017 Hyundai Hybrid Sonata lost power while in the middle lane of [XXX] . Following notice appeared: Check Hybrid system. Turn off engine !HEV. We were able to coast over to side of road (car was going 70mph at time of breakdown). Car towed to McDonough Hyundai dealership. Talked to Service Dept. We explained our situation to him (out of town, spending money on a hotel). They performed an engine electric Diag. which stated: Vehicle had multiple codes for low battery voltage. Test battery and got an instant failure. Cleared codes and test drove after new battery replacement. No codes came back. Approximately 1 hr. later in Jackson, GA we were on [XXX] , middle lane & engine stalled (70mph & coasted over to side of highway). Received same code: Check Hybrid Battery System, !HEV, turn off engine. Had car towed to Kennesaw, GA. Rented car to drive home & had car towed to Alexandria, KY our home town. After 2 wks. car was put on diagnostic machine. Said they test drove car multiple times. They said could not duplicate the issue. It was suggested the next time we get code on our dashboard to take a picture of it or video. Took car to Kerry Hyundai, Florence. Test driven car 40 miles & have gotten nothing. No codes. Told them it was imperative that your mechanics find the issue. I will not drive the car as it is now. It is unsafe as it stands now. Breaking down 2x in GA. The first time after driving it 6.5 hrs. and the 2nd time after putting brand new battery in & breaking down exactly 1 hr. after driving. We have been without our car since [XXX]. Hyundai advertises a great warranty on their cars, one reason we purchased it. We wanted a SAFE, RELIABLE car since we are both retired and going to travel. We are out of $1,827.08 & afraid to drive car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
