2011 HYUNDAI SONATA Complaints

Very high oil consumption. Tested with dealer and came out at 1qt/1 mile. Knok sensor detection system was installed while in warranty but they won't replace the engine.

The contact owned a 2011 Hyundai Sonata. The contact stated while driving 30 MPH the battery warning light illuminated. The contact stated that white smoke was issuing from under the hood. The contact stated that he depressed the brake pedal to stop the vehicle, however, the pedal depressed to the floorboard, and the vehicle did not slow.

The contact stated that the fire department was called and when they arrived the fire had spread to the passenger compartment. The contact stated that the fire department extinguished the fire with water. The vehicle was towed to an impound lot and the contact stated it was later declared a total loss by his insurance provider. The manufacturer was not informed of the failure. The contact had researched online and related the failure to NHTSA Campaign Number: 23V651000 (Service Brakes, Hydraulic). The failure mileage was approximately 200,000.

The ABS system has had a recall due to the potential for an engine fire. The initial recall was set on 9/22/23. Up until today (12/6/23) no action has been taken by the manufacturer but we are left without a car.

My car is at the Hyundai dealership now for almost 3 months to get 14 recalls done and also there was a lawsuit a few years ago that the engine was getting still an oil into the engine. My car was affected by that I just bought the car in 2021 I did not know about it. I’m needing them to swap out the engine as well and it’s been almost 3 months And it’s all recalls that are supposed to be done with my car 14 of them including the engine and the engine is part of the settlement that was done a few years ago Number was ran and it was a part of it, and it had me select the dealership I and that’s where I chose for it to go and it was supposed to be switched out for free

I was driving in the middle lane of the NJ parkway going 50mph and the car stalled. I was able to coast to the shoulder and have the car towed to my mechanic. Today I was information the engine is dead and I should contact the dealer. This a replacement engine as the first engine died while driving when the car had 70,000 miles. Hyundai replaced the engine but at 90,000 miles the replacement engine died. I'm wondering if you have reports of this happening. unfortunately the class action suit will not cover my 2011 Hyundai Sonata with 160,000 as it is over the years and mileage of the warranty. The warranty did not start at the time and mileage of the replacement engine but at the time of orginal purchase.

My Hyundai Sonata started messing up 3 months ago. My check engine light came on I took it to autozone to get it checked and it was my knock sensor wire harness I dont have a warranty on my car and I dont know what else to do

10/31/23 Car lost power on freeway. Dash lit up and stalled, I took picture brought to dealership. Could not find any issues or codes. 11/12/23 Driving on Pacific Coast Highway car started making knocking/ticking noise. Pull off to a side street and car hesitated and check engine light came on. Had it towed to dealership. Still waiting on assessment. Was told will take 2-3 days due to backlog. Clearly a known Engine issue dating back to recall campaign 132 Engine/inspection/replace. (I brought into dealership on 2/9/16 to perform checks on the 132 campaign - shows completed).

When I have my headlights turned on, and am driving my headlights flicker on and off. It mostly happens when I use the turn signal, but not always. sometimes it happens when I hit bumps. The headlights and the dash lights all go out when this happens, it usually lasts from 1 to 20 seconds at a time. I have taken it to my local garage(straight and clear) and they tested all electrical components and replaced the alternator and I still have the issue. They looked it up and determined that this is a known issue with the Hyundai Sonata, and one of the modules needs replaced in the steering column. This is a major safety issue because my headlights go out when driving and could cause and accident, and depending on the exact issue of the module it could cause a fire. There are no warning lights, just the lights go on and off. I will be getting the car repaired around November 9th 2023, because I need my car to be safe, and can submit my invoice at that time if this becomes a recall.

The contact's daughter owns a 2011 Hyundai Sonata. The contact stated while his daughter was driving 40 MPH, the engine seized. The contact's daughter was able to pull to the side of the road. The vehicle failed to restart and was towed to the dealer, where it was diagnosed that there were metal shavings in the engine. The dealer informed the contact that the engine was replaced with a rebuilt engine. The contact stated while his daughter was driving 50 MPH, the vehicle shuddered, and the engine seized a second time at 96,000 miles. The contact's daughter was able to pull to the side of the road. The vehicle was towed to the dealer, who informed the contact that there was no oil in the vehicle. The dealer performed an oil change on the vehicle, and the vehicle restarted. The check engine warning light was illuminated. The failure recurred a week later and there was no oil in the engine. The vehicle was towed to an independent mechanic, where it was diagnosed that there were metal shavings in the oil. Additionally, the mechanic informed the contact that the engine was not replaced but was rebuilt by the dealer. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened; however, no further assistance was provided. The failure mileage was approximately 61,000.

I started to get engine knocking noises about 6 months after the purchase of the used car. This knocking noise began to increase in frequency as I pressed my foot on the accelerator and the car would not accelerate when I pressed my foot on the gas pedal. Then the car would shut down in the middle of traffic. After waiting about 30 -45 mins, I would try to start the car again and would start and initially run as long as I drove less than 20 miles/hour the knocking noise level would decrease but if I went above 15 - 20 mph the car would shut down. The check engine light and engine oil light would come on. So I would check the engine oil level oil using the dip stick and it showed oil levels were ok. On October 10 2023 while driving to Walmart the engine turned off and would not start after waiting over 1 hour and I was stuck in the mall entrance road. A concerned driver with his passengers pushed the car to a Walmart parking spot where it is currently at. In addition, the traction light kept coming on and I paid the Hyundai dealership $2,800 to repair to keep the car from drifting to the left and to get the light off.
