NHTSA Complaint #11554063 — 2017 HYUNDAI ELANTRA

The initial problem was that the car began to stall out at slower speeds. This caused potential accident situations because of the sudden loss of control. We brought it to a service station which could not identify a specific problem. The car continued to experience this problem, so a couple of days later we brought it to a second service station. They thought it might be the crankshaft position sensor, so replaced that. While the second service was working on the car, they noticed a quiet knocking noise, which caused them to check the oil, which they found to be 3 quarts low, despite the fact that we had had the oil changed about 2 months (2,000 miles) earlier. There had been no warning light that the oil level was low prior to the service station checking it, and there was no indication of an oil leak. When we drove away from the second service station, the engine noise began getting much louder and the car again started stalling suddenly, so we brought it back to the service station. They indicated that the engine had likely been ruined as a result of the low oil situation, and suggested that we have it towed to a Hyundai dealership so they could address it. We did that, but Hyundai, after taking months to provide a response, determined that the problem was not one they would take responsibility for. We have done research and seen other consumers have this exact same problem, with similar non-support from Hyundai. I am also aware that there was a class action around this that seems to have been dismissed under odd circumstances. This problem is not akin to brakes wearing out; it is a clear manufacturing problem that causes very serious dangers to the public. Hyundai recognized this risk because they suggested a very aggressive oil-maintenance regimen to purchasers of these cars. They should stand behind their dangerous product. I have receipts and documentation supporting the above work by the service stations, including the prior oil change, if needed.
