2014 HYUNDAI SONATA Complaints

The contact owns a 2014 Hyundai Sonata. The contact stated that while his wife was driving at an undisclosed speed, she smelled an abnormal gasoline odor inside the vehicle. After a visual inspection of the engine compartment, the contact observed a fuel leak near the high-pressure fuel pump. The check engine warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the high-pressure fuel pump hose. The vehicle was repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 125,000.

The trunk lid on my 2014 Hyundai Sonata will not open. This is a safety issue since there is no way to access the spare tire if needed and there is no emergency exit. The left rear passenger seat is able to be folded down but it is the narrow one and there is no way to reach the seat release for the right-hand side which would allow someone to climb into the trunk and try to release from inside. Even then, it may not release based on what has been reported online. It seems there is a recall for later Hyundai Sonata model years (NHTSA report 21V619000 recall #208 for the 2016/2017 model year) but the problem exists as well in the 2011-2017 Sonatas. NHTSA should expand the model years in the recall or issue a new recall that covers the 2011-2017 Sonatas.

The contact owns a 2014 Hyundai Sonata. The contact stated that while the vehicle was at an independent mechanic for an oil change, the contact was informed that the engine oil level was low and there were metal shavings in the engine oil. The independent mechanic referred the contact to the dealer for assistance. The vehicle was taken to the dealer, where a second oil change was performed. The dealer also performed three oil consumption tests every 1,000 miles. In the first oil consumption test, the engine oil level was 2 1/2 quarts less. In the second oil consumption test, the engine oil level was 1 quart lower, and in the third oil consumption test, the engine oil level was 1 1/2 quart lower. The dealer informed the contact to return for the fourth oil consumption test after another 1,000 miles. The vehicle was not repaired. The manufacturer was made aware of the failure. The contact stated that the vehicle was previously repaired under NHTSA Campaign Number: 17V226000 (Engine and Engine Cooling); however, the failure recurred. The failure mileage was approximately 110,000.

when using the turn signals, either way, the headlights cut off. sometimes they flicker back on and sometimes they stay off.

When I am driving with my headlights on auto, every time I use my turn signal (and sometimes spontaneously) my headlights flicker. Sometimes it’s just for a second, but other times it has lasted more than 3 seconds which can be very dangerous while driving at night. It is also dangerous because other drivers may think I’m flashing my brights at them when im not. During this the dash will flicker as well. This has been happening since I got the car in 2018 so it’s not a battery issue.

Rear Driver Side door latch actuator assembly. Part failed and door cannot be opened even to change/repair the part. This is a major safety issue as the door cannot be opened by rear passengers.

There was the strong smell of gasoline so the vehicle was then parked outside of our garage. We had a scheduled appointment with our independent mechanic to have this looked at. Prior to the appointment, the Check Engine Light came on and was also flashing. The car was performing very poorly at this time. When the gas pedal was applied to accelerate the car sputtered and severely hesitated. We pulled off of the highway to a city street and then a parking lot to call for a tow to our mechanic. Upon inspection he found that a fuel line was leaking. He looked up to see if there were any Hyundai Technical Service Bulletins related to the issue. He found "Fuel Tube Replacement (Recall 227). Due to the recall we contacted the dealer Piazza Hyundai of Limerick (PA). The service representative (Jason) looked at the recall and stated our vehicle was not a part of the production line being recalled. All items in the recall were found on our car. We had our independent mechanic fix the fuel line. Prior to the repair the car was not in a drivable state.

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”.

Right brake light assembly melting around lightbulb and right brake light not working due to the burn. I went to multiple used auto parts store to try and buy the right brake assembly and noted multiple cars from 2011-2014 had the same issue.
