2014 Hyundai Sonata: grinding or squealing brakes

Filed Jan 16, 2025 · Engine · PA

I got a 2014 Hyundai Sonata in May of 2023. In the beginning of September 2024, I was driving down the road on a highway and a knocking sound began as well as grinding. The car then immediately lost all power which could’ve resulted in a serious accident like death or injury to me or others. I found out about the engine recall right after for the class action lawsuit for Hyundai. They told me I was good under the extended warranty. I was told that I needed to get the odometer branding fixed on the title before they would honor the recall. I did that and received the clean title in the beginning of November. The car was at a garage where they agreed that the car had premature worn engine bearings and had failed. The car went to a dealership in the beginning of November. Then I was told I needed more information like the clean title, bill of sale, and a statement. I provided all 3. After that I was told I needed to send receipts of my maintenance to the car. I also did that. I send every several documents. The dealership had told me my claim was denied due to “maintenance neglect” and “not enough maintenance documentation.” I then had the dealership reopen the claim and sent all of the prior maintenance records on the vehicle from the owner before me. I am told it is declined still for the same reason which makes no sense. I sent 35 documents to them. I was told today that they will not fix it and I was wished the best of luck. I did not have the car at the time of the recall and only had it for a year and a couple months. The car has been sitting for 4 months while I am paying insurance on it at the dealership to get the engine recall repaired.

Engine started making a weird knocking noise & was smoking from oil lid. Was driving & the noise got louder & then started to making a squealing noise. Started heading towards the dealership & it slowly started loosing power. Got to the turning lane to turn into the dealership parking lot, car immediately died in middle of road causing me to almost be hit by another vehicle . It started up long enough for me to make it into the parking lot. Car is now currently sitting at dealership waiting till Monday for Hyundai Service center to look at it. I originally had an appt scheduled for Tuesday to get it looked at but it didn’t last that long. speed limit was 35, I couldn’t even drive over 20 mph & had my emergency hazards on.

As I was driving on the interstate, 25 or so miles away from, my car started to shake and the service lights appeared on the dashboard. I pulled to the shoulder of the road, and shut it off, i turned it back on and it ran for maybe about 10 more miles until it happened again. This time, I turn it back on to get it to run and it doesn’t even begin to shift into drive. It started making a grinding/knocking noise from the engine & shaking, so I shut it off. I had to get it towed home and it has just been sitting in the drive way for a couple weeks now because it’s undrivable. I had no knowledge prior to this incident of an engine recall issued on the car, the dealer I bought it from didn’t inform me and neither did my lien holder. I contacted Hyundai of Slidell and they said since these open safety recalls have not been addressed that they will just reject them. There are about 2 from before I even bought the car that were issued in 2017 I believe that have not been completed. I bought the car in October of 2021 and was not informed of these safety recalls. Prior to this incident, no warning service lights had appeared and I was never told that I need to get my engine inspected as it ran fine.

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”.

From the time of my purchase of the car used in 2016 I noticed the the brake would sometimes make a squeaking sound if the brake pedal was depressed suddenly. In September of 2021 I noticed that a Brake Warning light would come on when starting the car. Sometimes the brake pedal would push to the floor as if there was no brake fluid pressure. I took the car to the Hyundai dealer and asked them to inspect and repair the problem. The problem was determined to be the ABS Pump along with the ABS Assembly. The units were replaced at a cost of $908.91. Later in June of 2022 the noise returned and the brake light again began to light. I didn't lose brakes but the light remained on whenever the vehicle was operating. I returned to the same dealer service shop and they inspected the problem and found DTC C1236. They checked pressure and it had 1054 Bar (needs to be 1000 Bar).The technician replaced the Hydraulic Electronic Control Unit and installed a Hybrid Noise Fix Kit. The cost for these repairs was $3351.15. I am aware of problems with other Hyundai model cars brakes. I hope that our car is safe to operate or park. The dealer confirmed the problems for both repair instances. I do not know if any other authorities have inspected this. I don't have the defective parts. The dealer service center retained them after both repairs.

The first time this happened I had just parked in front of my house and put the car into Park when I heard a chiming sound coming from the car, and the message Check Brake followed by Hybrid System Warning! Safely Stop and Do Not Drive on the dashboard. I did not drive the car for severals after this. After that, I started the car with no issues and was able to drive it with no issues but 4 days later I got the same message while out driving, I stepped on the brake and heard a grinding noise and the brake pedal went all the way to the floor. I pulled over, stop the engine, turned off the ignition, waited a couple of minutes afterwhich the car started with no issue and I was able to drive home. Today I took it to Hyundai garage for the service dept to take a look at it. I am waiting to hear back.

What seems to be random and without provocation, the car will sound a beeping alarm that only sounds on the interior, it will deactivate the accelerator (basically puts the car in neutral), and will display a warning message that reads "hybrid system warning! Safely stop and do not drive. Check brake". No matter what speed the car is traveling at, it can undergo this problem. If brakes are applied during this issue, it will sound as if the brakes are grinding and are not functioning properly. The issue can only be resolved by putting the vehicle in park, turning off the vehicle, and restarting it. If this is done, the car is back to 'normal' function. It has certainly been a safety hazard as it has done it multiple times in bumper to bumper traffic while traveling at higher rates of speed, and the car stalls out in the middle of the freeway. The hyundai service department has found no issue after running diagnostics, and says there is nothing that can be done to remedy the issue overall. I would estimate this exact issue has occurred approximately 20 times, periodically, over the last 6 months.

I sent you an email regarding the problem. You want additional information. But didn't say what addition information. Bottom line is I had brakes put on in may 2020 on my 2014 hyundai, they didn't feel rit., took car back, test ride, seemed ok. These brakes were manufactured by wagner brakes.; .for a few weeks when I pressed on brakes there was a squeal, while car was moving, and lately sounded like steel on steel. While care was moving took car back to jtires plus, brakes were defective, they replaced them with duralast gold brakes. I'd like to know if there have been other complaints against wagner brakes, and I'd like a full investigation of these brakes. The other issue is the recall on my 2014 sonata power train/gear shift; campaign # 123. This was completed in 2017; however, some months ago once the gear shift was in part with motor off, and I turned on the motor the shift would not move from the park position. I had to work with it a while; sometimes after a while I would put the key. Next to the shift compartment and I could shift the gear. I'd like to know if you have received any other complaints about the shift gear and how to have a second recall on campaign 123. The other problem is sometimes when I put on the e brake, it seems like the car would take too long to come to a complete stop. The other day after being parked, I turned on the engine, put the gear in reverse, but it continued to go forward. I had to turn the engine off and restart it and then put it in reverse before it reversed. I'd like to know if you've received complaints like this and I am requesting that my car be tested for the aforementioned problems free of charge due to all of the recalls hyundai has had in the past. In all of the situations above the car was on city streets, with the exception of the reversing, I was parked in a fast food parking lot.

I heard a grinding engine noise from the car. I took it in to ask what the terrrible sound was, I was told the computer pulled a "internal engine failure" code and it was no longer able to be driven. I was told they had a recall on earlier models but not the year 2014. I was told it needed a new engine, metallic flakes were found upon investigation at hyundai. I was told if the car continued to be driven it had a high risk of seizing up during use which would cause an accident. I was told it was recalled then later told that year 2014 had not yet been recalled, but that it was covered under warranty. They have had the vehicle for 2 months now and are stating I need to call the consumer protection agency and notify them of the situation to encourage a recall.
