I first experienced HEV hybrid system issue back in 2022. I took my sonata to the dealership which they had over a month to try to fix the problem which they did for the time. Now a year later I’m back with the same issues and the dealer basically saying they can’t see my car for a month then don’t know how long it’s going to take to fix the issues if the even. Nobody can really tell me what’s wrong with my car. This the second time it’s been a safety hazard while driving on the interstate and the system malfunctions causing a hazard to me and drivers around me because the vehicle has basically cuts off rapidly slowing the vehicle down

Over past 2 years, repeat alarm & message on dashboard, says, “Hybrid System Warning! Safety Stop and Do not Drive.” During attempts to back vehicle from garage, brakes grind. Seemed to be on auto-stop, trying to stop the vehicle from moving. On 01/03/22, brought car to Laguna Niguel Hyundai. Invoice notes “Caused by HISTORY CODES IN AHB C2112 C1102 C1237; NO CODES CURRENT CLEARED HISTORY CODES AND TEST DROVE VEHICLE NO CODES OR LIGHTS ON AT THIS TIME.” Was told history codes related to something about “voltage too high” and “Accelerator switch circuit [ABS switch]” and “wheel rear input signal.” On 11/28/22, brought car to Laguna Niguel Hyundai to address the ‘check engine light’ that was on. Service manager said “battery was not corresponding with the engine”, something about “HECU” and how it’s needed to “check brake reservoir for fluid – so I should pump it due to air bubble inside.” On 6/12/23, was driving more than 70mph; began losing speed, down to 0 mph. Stepping on gas did nothing. Drifted toward side of road & got alarm sound and message on dashboard, “Hybrid System Failure.” Terrified. No control of vehicle, 4 passengers, stranded. Towed to La Quinta. Notes on Hyundai La Quinta invoice: “VERIFIED CUSTOMER CONCERN SCANNED CODES P1B25 HIGH VOLTAGE PATH FAULT; P1B77 HIGH VOLTAGE PRECHARGE FAULT; POWER RELAY ASSEMBLY FALUTY SAFETY PLUG ASSEMBLY ARE FAULTY.” Notes also said BATTERY REPLACEMENT: BATTERY FAILED TEST Caused by BATTERY FAILED LOAD TEST. On 7/31, “HYBRID WARNING MESSAGE” returned. Alarm sound, grinding brakes – car undriveable. Towed for service. Invoice: “Caused by LOW BATTERY STATE OF HEALTH 53%. RECHARGE BATTERY TO 100% AND CLEAR DTC AND ROAD TEST.” While 7/31 work was covered under warranty, felt unsafe. Why battery health poor, when it was replaced 6 weeks before? Then came 8/30. Car disabled. Alarm sound & message says, “Hybrid System Warning! Safety Stop and Do not Drive.” Service manager said “hydraulic power unit failure”.

THE VEHICLE REQUIRES CONSTANT NEW OIL IN BETWEEN OIL CHANGES AND HAS BEEN LIKE THAT SINCE NEW. THE ENGINE BURNS OIL, AND IT IS NOT GOING ANYWHERE, NOOEN SEEMS TO KNOW.

Driving the car on the freeway, the battery light came on, and after that few other warning lights came on and I pulled over by then the car stopped and didn't turn on. It was scary since I was on the freeway. No other warning prior to that and the car was very well maintained even during the last recommended service everything was checked and no recommendation was made regarding the alternator. It was the alternator that caused the problem according to the dealer diagnosis.

The contact owns a 2021 Hyundai Sonata. The contact stated while driving 45 MPH, the vehicle inadvertently lost motive power in the middle of the roadway and failed to restart. The vehicle was pushed to the shoulder of the roadway, where the failure persisted. No warning lights were illuminated. The vehicle was towed to the dealer, who determined that there was no oil in the engine, causing the engine to seize. The vehicle was then towed to another dealer, who confirmed the diagnostic results. The contact stated that an oil change was performed three days prior to the failure. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 44,000.

The brake rotors are faulty and become warped at 9k mile I now have 27k and are extremely warped causing braking issues at higher speeds. I have been waiting over two months for new rotors from the dealer with no word as to when they will arrive. If the vehicle is left un-driven for a couple days the rotors will become rusted. Even the brand new vehicles in the Hyundia showroom are covered in rust. The suspension of the rear shock are extremely weak and bottoms out on the smallest rut. Cornering I’m the vehicle is subject to enormous amounts of whee hop which could result in an accident.

What component or system failed or malfunctioned, and is it available for inspection upon request? The Car continues to have inconsistent acceleration, hesitation, and sometimes lurches forward. On two occasions, the car felt like it was just going to turn off while driving. I was driving about 75 mph on I295 and driving about 15 mph on a residential road during the second occurrence. How was your safety or the safety of others put at risk? I feel as though I am not in complete control of the acceleration but am mostly concerned with the car stopping on it's own. I am very scared I'm going to be hit by the car(s) behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? I have an appointment in October for the car to be evaluated by a dealer. I hope it doesn't happen again before then. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? The only time a warning lamp came on was during the second episode when the car felt like it was going to turn off; the engine light came on and immediately off.

While exiting the vehicle there was a loud pop from under the drivers seat. Upon inspection the left front weld attaching the drivers seat to the positioning bar to raise and lower the seat bottom had failed and separated completely. This causes the front seat bottom to sit at an angle and not fully attached to the structure of the car, causing a severe safety issue in the event of an accident as the driver is not properly aligned for the airbag, the seat belt no longer aligns correctly on the body, and there is a greater risk of full seat detachment in a collision or while simply driving.
