ENGINE
While driving on the freeway the engine began loosing power and there is a knocking sound. My daughter was almost rear ended trying to get off the freeway. The vehicle was inspected by an independent mechanic and i was told the rod bearings are bad and the engine needs to be replaced. The vehicle has regular oil changes and does not consume a lot of oil. No warning lights came on. The dealership refuses to inspect the vehicle because it has a salvaged title. The failure happened at 108k miles.

ENGINE
Engine had knocking then completely froze while driving due to low oil pressure. Car has been well maintained, regular oil changes and just had axle repaired. Hyundai has extended warranty to cover this issue that is common on these vehicles and should cover the cost of the new motor. Consumer spoke with Hyundai corporate and the case number is [XXX]. Although they are well aware of cars catching fire and are even part of a major litigation lawsuit for this same situation consumer is getting nowhere with them.

UNKNOWN OR OTHER
The sunroof exploded while driving on the highway showering the vehicles behind me with glass causing drivers behind me to swerve and or change lanes violently. The explosion was so loud that it caused me to brake hard and to swerve. Hyundai has acknowledged the problem and issued an extended warranty on the sunroof which they are not honoring. My car was inspected by the glass company that repaired the sunroof and after the work was completed, by a Hyundai dealership. There was no warning. The sunroof just violently exploded nearly causing me to loose control of the car. Fortunately I had the sunroof visor closed which kept glass from hitting me and very possibly a loss of control of the vehicle. Can you help me to get Hyundai to honor their warranty?

ELECTRICAL SYSTEM
While driving on the interstate, the car began to jerk, and then the engine proceeded to rev as if the car needed a power boost to continue performing. The dashboard then said "Hybrid System Warning! Stop and Do Not Drive" and then the car would no longer accelerate and I had to pull over. This was an extremely dangerous and unsafe situation to be in, and unfortunately, the error only presents itself while driving so the mechanics are unable to get a code that clearly defines the issue that needs to be resolved. I have spent numerous hours on forums with complaints from Hyundai Sonata Hybrid owners who had the same issue and have visited various mechanics to fix the issue, only to end up having the issue arise yet again, further endangering their lives on the road. I believe the best solution forward is to take a serious investigation into the issue and issue an open recall so drivers can get the assistance they need to remain safe on the roads.

ENGINE
The contact owns a 2015 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the vehicle hesitated during acceleration and lost motive power with several unknown warning lights illuminated. The vehicle was towed to the dealer where it was diagnosed with engine failure. The dealer informed the contact that the engine needed to be replaced; however, the dealer declined the engine replacement due to the previous owner's failure to have the Manufacturer Service Campaign Number: 953 (ECM & Cluster Update - Engine Monitoring Logic Product Improvement) performed prior to the failure. The vehicle was not repaired and remained at the dealer. The manufacturer was not made aware of the failure. The failure mileage was 124,803.

FUEL/PROPULSION SYSTEM
While driving POV from work, I began smelling fuel in the air conditioning system from external intake. Upon further discovery, the high pressure fuel pump was found to be dislodged from the engine, due to a sheered bolt. This allowed fuel to spill out on the manifold and engine, also reducing power for acceleration. This issue could have caused a vehicle fire that could have engulfed the cabin if ignited.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
ABS and Traction Control warning lights came on, then went out the next time I started the vehicle. They then did this a second time. On the third time, they stayed on. Brakes worked fine, and vehicle had plenty of brake fluid. Inspection at dealership revealed left rear wheel speed sensor malfunction. Research discovered that this could cause a braking problem as the issue continued. Dealership verified this is a possibility. Dealership also stated they have had a number of vehicles report this issue; doesn't seem to be related to any particular year.

SEATS, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The powered driver seat returning from a reclined position can get stuck in the recline position for some unknown reason. The seat motor, electrical wiring system and the switch have all been examined and replaced and yet for some unknown reason it continues to occur. Two different mechanics thought it was the switch for the seat being faulty but its been replaced twice and still this issue can occur where the seat after reclining any amount the seat will remain in that recline position for an extended period of time (multiple days) and can if reclined completely, remain in the full reclined position unable to return in the direction so as to raise it to a normal seated position. The seat switch will only recline but will not return back to the seated position to any degree. All of the other swithces and buttons with the drivers side seat continue to remain operational and work even when the seated position direction does not function. To operate a vehicle in the fully reclined position is dangerous as you have no back support while driving, there is also no whiplash protection or support in the event of a collision. It can also impair the drivers ability to reach the pedals or operate the vehicle properly. It also makes the seat behind the driver unusable. Further adding to the danger the seat has no manual options and therefore is unable to be manually returned to the seated position, thus once it is reclined back it remains stuck in that position until the switch begins to function again or the seat is removed. There are no warning lamps or indicators and the seat continues to properly function in the recline direction. Only upon trying to return to a seated position is there any indication of an issue. This has happened at least 3 times in the past year. Repair shops have examined the electrical wiring and the switch and cant seem to keep it from happening

FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP, UNKNOWN OR OTHER
Anytime the car needs a repair on something (fuel pump, inhibitor switch, etc.) in the middle of driving the car will flash "hybrid system warning safely stop and do not drive" and then either slow to 40mph then die, or just die completely. This has happened 3 times before I took it in to be fixed. A few months later, it happens again. It doesn't matter what is wrong with the car, the car just senses an issue and dies in the middle of driving. Very unsafe!

ENGINE
1/2022. My vehicle start leaking oil. Vehicle was under warranty. Had multiple things replaced. I thought oil leak was fixed. Not even a month later in 2/2022, the vehicle was leaking oil again. Brought it back to dealer & they redid gaskets, seals, etc. Now on 4/22/22, I have not even put 3000 miles on the vehicle since it was at the dealership & there was a knocking noise coming from under my hood. Called the dealership and they said I needed to get it back to them. Oil consumption test was never done because it was assumed that my oil was low because it was leaking. Both times oil was put in my vehicle. On 4/28/22, I was at work and went outside to check my oil and there was little to no oil on the stick. I immediately added 5 quarts of oil which is required for my vehicle. The knocking did not stop. I left work to run a brief errand on 4/29/22, and had just pulled out of work onto a very busy four-lane highway. All of a sudden I hear this big boom under my hood, my car locks up and my oil light comes on. I immediately took my foot off of the gas and coasted into the next driveway at a business. There was oil all over the road and pouring out from under my car. It happened to be an auto parts store. A mechanic came outside and looked and said a rod went through my engine block & oil was pouring out of my car. I started to have an anxiety attack and went into shock. Luckily I was not on the interstate because it could have been very bad. I am now without a car. None of the rental car places have any vehicles available and I have a full-time job & am a single mom with 2 kids. The dealership was nice enough to have my car towed to them 45 minutes away. They then told me about an oil consumption problem with Hyundai and there is a big class action lawsuit. This should have never happened. Apparently the oil consumption was never sent out as a recall or anything else so I was unaware of it to even know to check my car other than regular oil changes.

VISIBILITY/WIPER
I was driving on I 205 N (Portland, OR), at a speed of around 65 MPH, when I hear a loud pop. Wasn't sure what happened, and first thing I thought was that somebody fired at my car... I realized that the air entering the car was coming from the sunroof area, and hearing the sound of shattered glass moving on the piece of material that separates the sunroof from the interior I realized that the problem comes from there. So I got out at the next exit, stopped in a WINCO parking lot and started assessing the damage and cleaning/ vacuuming the glass.

ENGINE
I had closed from work one morning and was headed home. Just a few seconds after taking off, my engine completely shut down. Thank goodness I wasn't in on a highway or at a heavy traffic area. I managed to park my car by the road side & tried to restart my engine, but the car wouldn't start. I towed the car to the nearest mechanic, only to hear that my engine is done & needs replacement. I've constantly kept up with frequent oil changes & always used synthetic oil. Current odometer reading is 153k & I believe the car still has the potential to stay on the road a longer time if the engine is taken care of. I've reported the issue to my nearest Hyundai dealership & they've asked me to tow it to them, but they can't promise that they'll take care of the problem. Worst of all, that's the only car I have & I'm still making payment on the car.
