Alternator/generator/regulator problems of the 2009 Hyundai Santa Fe

My 2009 Hyundai Santa Fe has stalled more than 4 times while driving since 2010. It loses power without warning rendering the vehicle unsafe and not able to be driven. The first time in 2010 it stopped while on the exit ramp of a highway doing about 50 mph. The car was brought to the dealership and they "could not duplicate the problem" so they did nothing. Brought same vehicle back to dealership in 2011, 2014 and 2019. Each time we are told "could not duplicate at this time". The most recent on August 7, 2019 they replaced the alternator and battery commenting that "vehicle now operates normally. Vehicle does not stall". The vehicle has since stalled again during driving. The dealership will only look again at the vehicle at the cost of $100. 00 per hour. We have contacted the corporate office and they were not helpful, in fact rude and hung up. After reading so m;any complaints on just this site I hope our government can help get Hyundai to be responsible for their vehicles before someone gets hurt or killed.

The battery light kept blinking, my battery is new, also the seat belt light for passenger seat kept blinking even when the seat belt was buckled. I stalled out and wouldn't start back up. I was in the street when it wouldn't start back up. I had it looked at when it was towed and the shop said there was alot of oil on my alternator and I would have to replace my value cover gaskets also.

The check engine light came on because of the gas gauge. Now I have no clue how much gas I have because the reader on the dash keeps going up and down. A month ago, I had the alternator and gas line replaced because of the last recall/service announcement. These electrical problems stem from that replacement.

I am having the issue with the gas gauge, where a short time after filling up the tank, the gauge drops to empty and then the check engine light comes on. I believe this problem was caused by the same issue as a recent recall, where oil was dripping on the alternator. Just a couple days after I received the recall for that issue, I began having electrical issues. My radio came on and off, my windows rolled up and down very slowly. On my last drive home, my electronic brakes stopped working, the steering was hard and the transmission began shifting up and down before I was finally able to pull over and have the car towed. Upon my drive home from the dealer after the recall repair, I noticed that a headlight was newly burned out. In less than a week, the other headlight burned out. On the same tank of gas I had since getting the car back from the dealer, the gauge first dropped to empty before the tank was empty. I believe something was shorted out in the gas gauge system, just as the headlights and all the other electrical issues that resulted from the alternator not working. Hyundai should repair the gas gauge issue since it was caused by the issue of their last recall.

While traveling on the interstate at speed (70 mph), car stopped responding to throttle with no warning. As I merged to right lane, car died completely and I had to maneuver to shoulder with no power. Stuck here with wife and 2 toddlers until towed to mechanic. The alternator was dead and had to be replaced. One year later, same thing (luckily not on interstate this time, and warning light did come on this time). Alternator replaced again. Later in 2015, Hyundai announced a maintenance campaign (#936), and I was reimbursed for initial 2 events, and local dealer completed the required maintenance in Nov 2015. 2 years later, same thing: warning lights, oil on alternator, etc. Local dealer again completes the work (thankfully at no charge to me). As of today, oil is on the alternator again, and I feel it is only a matter of time before the issue occurs again. As my wife is typically driving the kids around in this vehicle, I do not like the thought that it could cut off at any moment. I am hoping Hyundai will announce a permanent fix or recall. I am reaching out to them for advice on the latest recurrence. Initial event: 6/28/14 (mileage: 61020) 2nd event: 6/1/15 (mileage: 79800) Hyundai campaign completed: 11/19/15 (mileage: 89512) 3rd event: 08/30/17 (mileage: 119929) Feb 2018 (mileage: 127177) - notice oil building on alternator again.
