FUEL/PROPULSION SYSTEM
Noticed a smell of gasoline in the passenger compartment and took it to my local mechanic. Upon his inspection he found that the gas smell was caused by a crack on the plastic connector for the fuel line on top of the fuel pump. He showed this to me and recommended replacing the fuel pump as the connector is built into the pump and there was no proven way to fix the leak. Said leak caused gasoline fumes to fill the passenger compartment and therefore a risk of igniting a fire in the passenger compartment.

I have been notified in the last three oil changes to my 2017 Hyundai Sonata that it's missing oil. Today, I went to an oil change even before the oil change was due (the car noted it was not due for another 819 miles or 3 days). There, they told me the car has an engine oil leakage and that it barely had engine oil. I told them, the car didn't even light up as needing oil. They told me to visit a local Hyundai dealer to have it checked ASAP, as they have serviced various Hyundai Sonata and Elantra models with the same issue.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
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.

ENGINE
My engine seized while driving down a mountain and I had no acceleration at the bottom of the mountain. If I would have been in front of an 18 wheeler while experiencing this failure there is a good chance I would have been in a wreck. Luckily I was not in traffic and was able to find a place to pull over at. There is no where to pull over safely on said mountain unless you’re an 18 wheeler. There is a recall on my engine by Hyundai corporate but there are no dealerships servicing the recall anywhere I can find. The vehicle has not been inspected yet because they are trying to charge me $150 for the inspection that the Hyundai website says is free for the recall. There was no warning to this happening, there was no engine light, oil light, or anything that came on before the engine gave out on me while driving.

FUEL/PROPULSION SYSTEM
While driving the car it suddenly decelerated and multiple warning errors on electronics, driver assist, braking started going off then the error message of Check Hybrid Turn Engine Off came on. I was able to coast into a parking lot as the car could only go around 5 miles an hour. I turned the care off and on and the Check Hybrid Turn Engine Off remained for the 2 hours it took to have a tow truck come to take the car to a dealer. The car has 16,383 miles and prior to this there was no warning or error messages. The dealer hasn't reviewed the car yet, but the fact that it immediately, with no warning, decelerated and would go only 5 miles an hour is very risky and unsafe.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The car has had multiple issues with the hybrid system. I’ve taken it to the dealership about 4-5 times. They “fix” the issue but a little while later I’m having more hybrid warming issues. This last time I took it to a different dealership, paid for a diagnostic test, and was told my hybrid system was bad but because it was repaired too many times instead of replacing it, it’s no longer covered under warranty. The issue from the last diagnostic test showed the master brake cylinder was faulty, I replaced it but I’m still having the same issue. The mechanic I took it to did their own diagnostic test and it showed there is an issue with the hydraulic booster, high pressure accumulator short term charge. When I searched the issue, I’ve found that many people are having the same issue with the same car/year as mine. I contacted the manufacturer and they are still not willing to fix it even though it is a possible defect in the car.

The first time my engine light came on was about a month after I had purchased it. The dealership told me to go to autozone to see what it could be. Report said it could possible be an oil clog or oil change. I got an oil change and the light was off. Light came on an every now and then but the car was driving fine. I got another oil change at the recommended mileage. My car won’t start now, I thought it was a battery issue so I took it in to a mechanic to have it looked at and they said I need a new engine.

ENGINE
I purchased a 2015 Hyundai Sonata from Carmax on 12/6/22 in Tinley Park, IL. The motor on the car went out on 8/30/23. I took my car to family mechanic to find out that the motor has a hole in the back of it. I had it towed to Happy Hyundai on 9/1/23 in Oak Lawn. I was by Happy Hyundai that they will not be able to look at my car for for 4-6 weeks. Carmax claimed to have did an all point inspection on the car but yet the motor went out. I’ve only had the car for 8 months. The motor went out while I was driving on the express way going over 50 mph. My safety and others around me was put at risk. Luckily me and no one was hurt. The only time the engine warning lamps came on while I was on the expressway and that’s when the car started to slow down while trying to get to the right side of the expressway.

VEHICLE SPEED CONTROL
My concern is a potential unintended acceleration forward as. I was. parking vechicle. Sudden burst of speed, went thru shrubbery and off a 2 foot wall. Felt as if we were taking off a runway in a plane. Car went nose up over the wall and then dropped into a neighbor yard digging a divot, ripping rear left fender and bumper with some undercarriage problems. My spouse and I were seatbelted and not injured. I can not recall any safety warning until car stopped and then do recall a message being on dash but cannot presently recall what it said. Vehicle currently being worked on at collision center where Insurence Appraisor gave go ahead with estimate to repair damages

VEHICLE SPEED CONTROL, SERVICE BRAKES, EXTERIOR LIGHTING
The brake lights stay on all the time, thus preventing vehicles behind mine from knowing if I'm actually stopping. Hence, they may stop without reason, and endanger drivers behind them. The manufacturer has likely known of this being an issue in Sonatas from, at least, 2007 through 2013 models. The manufacturer is putting the task of solving the problem (if that's even possible), upon a dealer. And, my trip to that (nearest) dealership (75 miles away) creates its own danger. The danger is added to by a pre-existing unsolved issue of the horn not functioning. As per the brake light issue, I've been to the dealership about it twice, and they weren't even aware that the brake light switch they think attaches to my car doesn't. So, I wonder if the manufacturer tried to address the issue in the middle of the 2011 model year, installed a different model switch and wiring on more newly built cars in that model year, and decided to ignore the owners of vehicles sold earlier in that model year. As for an additional related issue, unless I disconnect my battery when not in the car. the lights stay on and run down the battery. That can contribute to its own safety issue.
