1. I purchased this vehicle in 2016 and I have had my rear brake lights repaired several times because the rear tail lights continue to go out, This happens regularly. There is no warning lights on the dash to indicate an issue. The only way i learned that my brake lights don't work properly is another motorist driving behind me and almost rear ending me. I have had the rear brake lights repaired by the dealership before. My brakes always smell like burning rubber after driving having me to believe that the lubricant for the brake pads aren't working. 2.The dashboard lights also periodically blinks out without warning. After a few moments it will illuminate again. 3. My seatbelts sometimes doesn't tighten up. I have to pull them several times for them to catch and return after the seatbelt isn't in use.

So my car started to stall when I started it an when I started goin down the road like it wanted to die. Then I started to smell gas very strong so had a code tester put to my car an i have 6 permanent codes. An not only that im smelling oil strong an noticing big oil spots under my car. So I look under the hood an behind the turbo I see oil behind an underneath the turbo. I definitely didnt feel safe driving but now its not even drivable. I purchased it couple months ago from an individual an i cant belive the amount of problems this car has. Im a single mom an trying to support my family an its hard to now with a non running car. I've put quite a few parts hoping it would fix some of the problems an nothing has. I absolutely love the car an very beautiful but unfortunately to many problems with it. Eninge, gas leaks, timing

I had an issue on my car where engine oil level is getting low day by day, then I have visited service center to solve they have said to change spark plug, pcv value and also done fuel induction service , said me to come after 1000 miles then after I had a another problem where my car RPM is increasing and speed is getting low. I have visited the service center again saying catalytic converter issue and asked me to pay 3000$ to do repair before that I have paid 700$ but mentioning you one thing till now I have spend 2000$ for the same issue what was happen. Today as now my car is issue to move in toll road it is very hard to move. And also Hyundai is denying my request and saying me I am out of warranty. My car has 94000 miles as for today. Please help me out from this I am struggling with the issue.

I have a 2013 Hyundai sonata in which the engine was recalled close to about 2 years ago. About 3 days ago my engine just randomly gave out on the highway in rush hour traffic the middle of me driving. And now I am without a vehicle and my car is sitting at lake Norman Hyundai dealership.

WHILE DRIVING AND USING THE ACCELERATOR , THE RPM WOULD REV UP BUT THE CAR WOULD NOT MOVE. THE CAR WOULD THEN JERK BACK AND FORTH. ONLY ABLE TO GO APPROXIMATELY 10 MILES PER HOUR, BUT THE RPM WOULD GO AS HIGH AS 6K OR 7K RPM. DANGEROUS TO DRIVE. WHEN IDLE, ALSO FELT RPM GO UP AND JERKING MOTION

When driving, an acceleration would sometime cause the car's RPMs would drop to zero with the throttle of the vehicle responding poorly. A lose of power occurs and the takes about 15 seconds to feel some power return to the throttle. The feeling of no throttle occurs which is very scary when your reason for accelerating is to pass a vehicle but the sudden lose of power makes it difficult to accelerate properly to pass. The RPMs remains none responsive. With the loss of power, the traction control light came on. When the vehicle is turn off and turned back on, the car's issue disappears. But the problem randomly occurs again.

We were part of the Hyundai Theta claim group. Our car did stop in traffic, luckily my husband was alone, and no one was hurt. It was towed to the dealer. This was October2023. Dealer gave a list of fixes & stated it had nothing to do with theta. We had all recommended maintenance done; as we always do. Roughly 2 months later, Dec., with a full car, it did it again, at a stoplight. We are lucky to be alive. We had it towed to our mechanic. I contacted the Theta claims line. Our mechanic stated oil was still in the filter, but the pistons had blown clear through the engine, which he still has. Hyundai contacted him. He sent pictures. Hyundai denied my claim for timely filing. I have called weekly, followed every instruction. Now they want me to mail a letter. I am a disabled veteran. Look how many recalls they have. They don't mind recalling. They will just deny people. Please help.

My 2013 Hyundai Sonata lost acceleration power while on the road requiring an emergency departure from the road and it fails to acceleration beyond. Placed vehicle in park and attempted to proceed home but was only able to drive 5 to 10 mph max creating a dangerous situation for my fellow commuters and myselt. After about a few block I let the vehicle cool down and attempted to proceed home. The car would only go up to 5 mph requiring me to avoid rear end collisions. Ultimately, requiring a tow vehicle to bring it home. Our neighbor indicated it is the MAP sensor which was changes with no improvement to the car's acceleration issues. Checked all the fluids and assured they were correct. This vehicle has place me and others in a dangerous and potentially fatal situations.

The main power relay for the hybrid battery shorted out causing the safety plug to also short out. I was driving down the road in a rural location and an error message came up on the screen saying hybrid system error, pull over immediately, and the car would not restart after I pulled over. The car was towed to the dealer and the dealer said that the power relay and the safety plug were shorted out. The main issue that I have is that the hybrid system warning light has come on multiple times and the car had to be towed to the dealership. They always said it was a software problem. The hybrid system warning pull over light first occurred 5 or 6 years ago.

Car has been knocking for a couple of months now, check engine started flashing and it lost acceleration. Towed to shop and code for knock sensor was reading bad. Shop replaced knock sensor, I picked car up and drove away and it happened again. Engine light flashing and lost acceleration, took back to shop and the next day which would be today they said take to the dealer cause it's still reading for knock sensor. My 2013 hyundai sonata 2.0 is now at the dealership in line with the rest of the seized engines. So I have spent $800 ($613 for shop and $200 rental car) and my car is still not drivable. Now I'm back in a rental at$300 a week until hyundai diagnose, test, and approve the process of fixing the issue with my 2013 hyundai sonata 2.0, it has a life time warranty!

We were travelling from Minnesota to Arkansas to see our family for thanks giving on 11/24/2022. Car engine starts blinking and engine started to make rattling noise. Took exit and pull over our car in one of the gas station. It was closed, this was our first road trip and first time in Iowa. Called insurance and towed our car to O'reaily auto part. They found out the error code p1326 which is related to engine issue. Looked for nearby Hyundai dealership and booked hotel near them. We went to Hyundai dealer at 7:00am on Friday 11/25/2022. We told them what happened. They told us they will check in our car. We waited from 7am to 1:30pm our car was still outside. At 2pm service manager came and said they cant check our car. We booked rental car ourselves and decided to come back home. We forgot our apartment key went back to get it and they had already started to diagnose our car thinking we are gone. Service guy told me that's engine failure every Hyundai is facing now. My car have 61k miles on it and I bought it in 2020 from Hyundai dealership. I still have 9k loan to pay this car and i cannot afford new car or new engine. I do not have car now and they are saying it can take months to repair my car if it gets approved for engine replacement. Hyundai is playing with my life and put me in depression. I have no option other than to cry. I am feeling so helpless now. Nothing and nobody seems helpful. I try my best to do anything i can and i am just waiting for coming Monday for Hyundai to make excuse to not fix my car. Hyundai is playing with lots of people life. This might be small for them but not for a working people like us. My life is messed up because of them. I cannot sleep at night and I have been calling everywhere if I can get help.

While driving car started beeping and making noises - check engine light, brake light, lcd displayed brake warning and flashed "hybrid system warning! safely stop and do not drive". Brake pedal then went to floor, and engine power reduced. Re-starting the car only cleared the problem for a minute before the warning message re-occurs. Others have encountered this issue resulting in crashes. https://www.carproblemzoo.com/hyundai/sonata/2013/service-brakes-problems.php also reported here: https://www.carcomplaints.com/Hyundai/Sonata/2013/brakes/service_brakes.shtml

Was losing power while driving, oil consumption issues (had to add oil every 1000 miles). Engine started knocking and went into limp mode, had it towed to dealership where they said they fixed it ($1100). Less then a week later while driving on the highway lost lower, went into limp mode (89 mph to 15 mph in seconds) and was almost hit by a semi truck. Car has been sitting at the dealership since May 2022, they said I need a new engine but Hyundai declined.

My car seized up a lot, like pushing forward, then all together stopped and went into only going up to 40mph. I just hot the car 10 months ago so it shouldn't have done that. Took it to a repair shop and they said the engine was on it's last legs even though I literally just got the car.

Ref: NHTA Recall Number: 20V-746 Hyundai REcall Number:198 (2nd recall fix ) After the above recall fix we had informed the Hyundai about engine heating up, we were told this is false alarm and car has monitoring system recall issue, Recall would would be mailed. I have all the dealer bill to prove the engine was heating up, they replaced certain part at our expense ( bill attached ) After above recall Fix by Hyundai Dealer in San Leandro, CA. we had engine overheating and car started engine started vibrating & I could see smoke from the exhaust. it ceased in the middle of the highway. Please note: Our Car has been services by Hyundai dealer. Note: if you look at the second safety recall notice, It does state in safety notice about engine compartments fire while driving for many reason and depending on the severity of the fire. the identification of the cause can be untraceable.. Above incidence happened just after your dealer did 2nd recall fix. IMO - It proves that recall fix was faulty and overheating engine cause the engine blew-up. Car has been with the dealership repair for 3rd recall. since a month Hyundai dealer asking us $9K to fix the car. I have reported the incidence to Hyundai Corporate under the case # 18811202. They are not responding. Dealer did contact Hyundai Corporate to get the engine change request, either the request if denied or gone unanswered.
