- engine had metal shavings in it which led to excessive amounts of oil consumption, it took the dealership almost a year to admit that the engine was going out -the brake light switch keeps going out, I have replaced my third switch in my 7 years of owning this car. -the taillight wiring harness warp the taillight housing for the brake lights due to excessive heat generated from the 2537 bulbs. In general, the wiring harness don't even last that long

First, my low beams quit working months ago. Bulbs are good. I even took it in to a shop to have it checked. They said they couldn't find anything and that it was an electrical issue. That makes sense since I just started having issues with the dome lights inside as well. Have to have the inside lights turned off or they will not go off. Most recently, on the highway on my way to work, my car lost power and the dash lit up with lights and I had to pull over. Started making a loud clanging noise as well. Took it to the shop again to get it looked at. They said my oil was almost gone. No oil on the dipstick. I just recently had the oil changed! should not be out of oil. They further noted that there were no signs of oil leakage anywhere. Suggested that the engine was faulty and was excessively burning oil. Not sure what I aza M supposed to do now. I have a issues with safety due to my lights not working, and a bigger issue with my engine not working properly. I need help!

I bought a 2011 Sonata 24 hours later I took it on the road. Just as I get an hour away from home I was going up a steep hill... the next thing I know my rpms shot up past four and then next thing U know every light on my dash came on and my gas peddle stopped working. I also made sure to get an oil change before I left. Once I finally got the car towed back home I tried again to start it now my engine is knocking... I contacted the guy who sold it (licensed to sell cars) mentioned he did not know of any recall. Will be calling a Hyundai dealership near me in the am for more info.

Sonata 4-cyl

  • 156,000 miles
I was at a complete stop and when I accelerated to approximately 15-20 mph, the rpms increased to over 5,000 and engine began to shake however when pressing on the gas pedal vehicle would no longer accelerate. My engine, eps, and oil lights all illuminated and vehicle stalled in the middle of the lane. Vehicle ignition would not engage after stalling. I had to have the vehicle towed. In Sept of 2019 I had a similar issue with high rpms, vehicle not accelerating properly and safety light illuminating. I brought it in to the dealership where we purchased it used (June of 2019) and they claimed they could not find any problems. No recall was mentioned by them so I am assuming it was never looked into. Had it not of been for the tow truck driver I would have never been made aware of a possible recall issue.
