ENGINE
First time I took my vehicle to the shop for over consuming oil they replaced the oil and cleaned all the parts. A few months after this my car would not accelerate properly and had a loud knocking noise in the engine and check engine light came on. After taking it to the dealer I was told I would need to replace the whole engine. I have proof of proper care done on the car but since I am second owner it is not covered in the original warranty. My car could have stalled and resulted in me and my family injured at the least. Hyundai knows about these issues and needs to recall the engines.

There is excessive oil consumption with the engine in my car. Hyundai says 1qt per 1000 miles is “acceptable” however this is not acceptable and can lead to catastrophic engine failure and oil slick on roadways if not caught in time. This is a know problem with Hyundai/Kia at this time. In many cases Hyundai/Kia owners are left with a “lemon” of a new car that is currently in warranty. Some have been granted replacement engines that have not lasted 3000 miles. A recall must be issued in the name of safety on these cars. The manufacturer must be held accountable for the lack of quality that has been put out over the last decade.

ENGINE, POWER TRAIN
While driving, engine alerted that it was overheating. Pulled over and coolant was very low, so I refilled it and then while driving to my family's garage to use the lift, saw white exhaust smoke. Took it to an independent mechanic, and in the ~10 mile trip there, over a quart of coolant had been burned off. He was able to reproduce the issue. No issues with the engine operation, it runs well and efficient, no check engine light. Mechanic found that a coolant line runs to the middle of the exhaust system and that this seems to be the issue. Other owners seem to have reported this same issue with this same model and roughly the same year, in which the muffler assembly needs replaced due to coolant leaking into the exhaust. Only prior issue was less warm air out of the vents for the previous week or so, but no other issues or warnings.

VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM, ENGINE
The vehicle has twice been disabled while driving due to “lost communication with hybrid module powertrain control module.” This breakdown is a significant safety hazard as the car loses power and coasts to a stop without any warning. The second time was on a 65 mph highway. Neither time has had any warning before the malfunction lights appeared. The first time occurred on 10/7, and the vehicle was towed to the dealership. Nothing was done besides clearing the trouble codes and test driving with the car, which returned at the end of October—the second time the breakdown occurred about a month later on 12/3. This second time, I removed the code myself on the roadside so as not to be in more danger, and I am currently awaiting an update from the dealership’s service department on their next steps after initially being told to just have it towed in again. Losing power without notice is incredibly concerning. I want to report this safety issue and determine my next steps to resolve it, as this has dramatically impacted my trust in the vehicle and its safety.

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.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING
The plastic housing of the brake lights have turned black. I'm on my second set that I got at wrecking yard. The plastic doesn't hold up to the heat of the tail/brake light. I saw other cars like mine with same problem at the wrecking yard. And my ground wire to my radiator fan burned out as well during COVID. I think Hyundai used cheap plastic that can't hold up to the heat. My dash cracked really bad as well. All over. I saw the same cracked dashes of other car in wrecking yards. They know they had a plastic defect and they changed body styles the next year. My door handles brake off in my hands and the a/c vent broke twice. They have hazzard car because all of this happened early when I purchased the car. And my car has Hyundai and Kia parts old body style 2010 bought end of 2009. Theta 2 engine. All of the recalls but they leave my car out. And that stop brake switch light has broken so many times. Replaced free only 1 time by dealership. Other times I had to pay for. Cheap plastic. If I need repair by dealership , I have to leave car on their lot for 6weeks for them to look at. Not appointment. Leave my car on lot until it's my cars turn. And my car just quit running once while driving in my apartment complex. It also quit running driving down the highway.. everything shutting off and lights turned on dash. The battery light was on first, then the check engine , abs, and all lights coming on. I tried to turn on my hazards but everything was failing. I was lucky I wasn't hit by other highway traffic. My headlights went off or really dim. I was allowed to drive really slow to a roach hotel just there on interstate. I was told it was my alternator. But I think it was something else that caused failure. I did have my car professionally washed, that day. (Hardly do that). And the week before it was at Hyundai shop for retinting of windows which my battery was dead in their dusty lot when pickup. That brake light switch lamp stopper was broken and laying in floor l

Between oil change intervals, the check engine light flickered intermittently. I checked the oil level and it was very low. I added 3 quarts of oil and took it to my Hyundai dealership. They performed all the oil consumption tests and told us that the car now burns seven-tenths of a quart every 1000 miles. Hyundai USA claims that this is acceptable oil consumption. I disagree of course. I called my service adviser at the dealership and requested that Hyundai replace the engine because a 2015 Hyundai Sonata with only 70K miles should not be burning that much oil. He agreed and told me to keep monitoring the oil consumption and if it burns 1 quart or more after 1000 miles, to bring it back.

SERVICE BRAKES, ELECTRICAL SYSTEM, WHEELS
The ABS (Antilock Brake System) or BMS ( Brake Module System) warning light illumination came on flashing “DO NOT DRIVE “ and the brakes sieze-up making it impossible to drive. Key Hyundai in Jacksonville previously charged me $2600 to replace the BMS and within warranty. A few months later the same company charged me another $342.56 to diagnose the same issue. I had to rent a car for $700 while in the service repair department. Key Hyundai was unable to fix my 2012 Sonata hybrid except offering me a replacement hybrid battery and control system for $12,900. I declined. I believe that the campaign 251 involves this problem. I had to get the car towed to another mechanic that is currently working on the vehicle.

AIR BAGS, SERVICE BRAKES, HYDRAULIC
The contact owns a 2004 Hyundai Sonata. The contact stated her fiance was driving 20-25 MPH on a steep hill with her in the front passenger's side seat. The contact stated that her fiance depressed the brake pedal to come to a complete stop at the stop sign, but the brake pedal went down to the floorboard, and the vehicle failed to respond. The contact's fiance veered to the left and intentionally hit a telephone pole to avoid crashing into a parked vehicle, and to prevent a more severe accident from occurring as the road was significantly steep. The brake warning light was illuminated. The air bags failed to deploy. The contact sustained a seatbelt mark. The contact's fiance was not wearing a seatbelt and hit his head against the windshield. The contact's fiance sustained a concussion, a laceration on the chin, a chipped front left upper tooth and bruises on the bottom teeth.

The dealer was not notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was approximately 185,000.

Oil consumption issues. Had a brand new factory motor to replace original motor due to engine failure from oil consumption issues on June 29 2020 at 154,285 miles. The new motor only has 56,665 miles on it and I'm having to add extra oil in between changes because it is bone dry after about 1800 miles from oil change each time.
