| Description of the problem | My sonata has started stalling and shutting down without warning. The first time it happed was dec 12th. I just finished accelerating from about 35mph to 60mph. There the vehicle made a loud thump and the engine shut down. Seconds later i lost power steering, dash lights, and headlights. The car restarted without issue. The same problem happened on dec. 16th while traveling at a constant 30mph. I experienced the same symptoms as before, except the vehicle did not shake or create a loud noise before shutting down. Mileage was at 75980. Temperature was in the 20's. I took the car do the dealership and they could not find anything wrong or recreate the problem. The third time this has happened was dec 29th. I was traveling at 20mph and coasting to a stoplight. It was 19 deg outside and the mileage was around 76800. So far the car has not shut off when the weather is above freezing. Lower temps might be contributing to the problem but not likely to be the primary cause. In all cases the car was at operating temp and was running for more then 30 min. It has not yet shut off while accelerating. Only maintaining speed or coasting. About a two months ago the dealer did a software update on the vehicle due to a claimed recall. The issue started about 2-3 weeks later this is definitely a safety issue since it happens without warning. I did find some other complaints similar to this while searching. |
