I have been receiving important safety recall notices from Hyundai Motor America since February stating they are preparing a remedy. The ABS modules could malfunction and result in an engine fire while I am driving the vehicle or it is parked. This is very concerning. Each time I have my car serviced I ask Hyundai service dept. to address the recall and I am told the part is not available.

It has been OVER 6 MONTHS since there has been a recall on my vehicle (Hyundai Recall 218 / NHTSA Recall 22V-056). It is a MAJOR safety hazard which could cause an engine fire while parked or driving and there is no remedy as of today, Aug. 7th. This needs to be addressed asap. NHTSA might also want to check their numbers/email. The number provided on the safety recall docs automatically hangs up on me when I try to call NHTSA @ 888-327-4236, and the email address provided (https://www.safecar.gov) says site can not be reached.

Even with have oil changes regularly and just about 2,000 miles ago *synthetic oil* the car started making very weird noises when accelerating and randomly having the oil light pop up. As I drove down the highway, with the pedal to the floor it would not speed up, the car then completely died and would not turn on. After having it towed and inspected they declared the engine was done and could not be fixed. They then informed me that because this issue is SO common it makes it extremely hard and expensive to find a replacement engine.

I was driving on the highway about 5 minutes away from home when I was avoid a reckless driver. (I called and reported it to the State police) Once I was trying to switch lanes my engine seized up in the middle of the highway. I keep up with the maintenance so I have no idea why it would do that. After getting towed and bringing it to the nearest dealership I was told my engine seized up and now I need to bring it to a Hyundai dealership to get it inspected before receiving service. I wont rice service until August 31st. This all new to me because my car fall in the recall of the many Hyundai's. How can I get rid of my vehicle as a second owner who bought t from a dealership? I don't feel comfortable or safe driving a vehicle like that.

While driving the vehicle suddenly went into a limp mode and had a flashing check engine light. The vehicle was in limp mode for approximately a half mile prior to having complete engine failure and shutting off completely. Vehicle has always been properly maintained. Dealer confirmed engine is seized. A manufacturing defect with the Theta II engine caused the premature engine failure. If this occurred on a major highway myself and other motorists would be put at a significant risk as there was limited time to act and find a safe place to roll to a stop.

I currently represent Mr. Jeffrey Harvey as his attorney. Hyundai has failed to provide a remedy for more than four months for Mr. Harvey's vehicle. The recall campaign has not sent further instructions or details about the proposed remedy for the problem with the vehicle. Please advise as to exactly how long Hyundai has to come up with a remedy for the vehicle, and what exactly the options are for reimbursement of out-of-pocket expenses.

As part of Hyundai's class action lawsuit settlement, Hyundai promised to fix defective engines reporting the P136 error code and provide alternative transportation until the vehicle's defective engine is fixed. Instead I am without a car because Hyundai corporate claims they are "too busy" to fix it. For three weeks, Hyundai corporate has known that the engine of my 2015 Hyundai Tucson has reported the P1326 error code, and has been sitting at Key Hyundai at 4660 Southside BLVD; Jacksonville, Florida. Hyundai has refused to provide us with a loaner car, or authorize us to get a rental car, as required under the class action settlement, under the basis that the inspection has not yet been performed on the vehicle. When we asked for them to help find another dealership to inspect the vehicle, or any other assistance they could provide with alternative transportation, they refused. Hyundai assigned us a case manager, Ricardo (case number 19759747), who has repeatedly lied to us, and refuses to return our calls. For example, he claimed that he called the dealership to try to help us, even though the dealership reported no such call in their records and Hyundai confirmed that they did not have this call in their records. Hyundai refuses to assign anyone else to help with this matter. We have been calling Hyundai almost every day for three weeks and they have provided no assistance whatsoever. The constant theme has been to "sit and wait". I am requesting your office to help so that other Americans are not victimized by Hyundai. Hyundai promised to make the victims of their defective engines whole, and yet instead have vehicles subject to the class action lawsuit sitting around for weeks, and refuse to provide any assistance whatsoever with alternative transportation. Americans could lose their jobs and be forced into financial insolvency because of Hyundai not honoring their settlement agreement.

My car has been subject to safety recall for its anit-lock break system module system since February 2022. It is now the middle of May, 2022. Hyundai, in the Sacramento area of California, says they do not have parts in stock for performing the mandated recall and will not call me back or give me any estimate for when I can have the part. The Hyundai of America representitive just told me I could keep calling, putting the burden on me, and not assisting me further in terms of becoming part of a list of people that still need the recall done, etc.. The notice says my car's engine compartment might catch on fire while parked or driving without this recall. That's pretty ridiculous and unsafe. They need to provide a remedy.

I bought My SUV on January 14th 2022, and it presented a recall problem on February 05th, 2022. On the way from Bethlehem to New York, my daughter was driving the vehicle, when it slowed down in the middle of the highway, put my daughter live in risks and it did not accelerate and she moved to the edge and called 911. I called the AUTOProved staff, the dealership I unfortunately bought my SUV from, immediately when my car broke down. On February 23rd the warranty company sent me a tow truck, which picked the vehicle to the dealer's shop from my house, and the Dealer's staff have been providing misleading information to me ever since. (They told me I couldn't call Hyundai, because this vehicle was in their name.) Now, I completely understand that my car might not be the only one they or you have to work with, however, as you may notice it's been two entire months and neither the dealership, nor the Hyundai company have provided me with neither a solution, nor any service, or helpful information to my problem. I've exhausted every possible method to get an answer from the dealership. I've emailed them, called them, personally went to the site several times, sent them messages, and they have been giving me false information about my vehicle, ignored my calls, picked up and said they will call me back with information and never called, or say that nothing can be done about my car and/or that it is MY responsibility to pay for the recall problem of my car for it to be fixed after previously telling me that I didn't have to pay for anything and as you state on your letter to me. On March 18th 2022 the AUTOProved staff, told me that my Tucson was towed to their shop and that they will have to work on it because you, Hyundai, refused to fix the problem. Lastly on March 31st I called the Warranty company to claim the rental car refund, but they said that they did have not a claim for the vehicle from the dealer staff.

Previous History: Vehicle already required an engine replacement - short block assembly. Current Details: DTC P01326 - While driving - Check Engine Light blinks & vehicle's acceleration is immediately reduced, causing dangerous disruption to the flow of traffic while merging into traffic from exit ramps, at traffic lights, stop signs, turns etc. Has been to dealer 3x for diagnosis and repair. Jan 2022 - 1st attempt - Knock Sensor replaced (Recall 966 was performed in Nov 2021) 2nd attempt - Knock Sensor software updated - 3rd attempt - Knock Sensor disconnected and reconnected. After each repair attempt the vehicle continued to suffer reduced acceleration and blinking check engine light while driving within a day or two. 4th time - DTC P0087 - Fuel Rail/System Pressure - Too Low & DTC P2191 System too Lean at Higher Load (Multiple) (Bank 1). These are "new" codes discovered by subsequent Hyundai dealership after the 3rd repair attempt unresolved by the original selling dealership. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others. The warning check engine lights did appear at the same time as the reduced acceleration and occurred each time spontaneously while driving. The vehicle is available for inspection upon request. There are additional complaints involving 2015 Hyundai Tucsons listed on the NHTSA website which I do not see connected to a current or previous recall. However, I do see Hyundai issued a recall # 207 in 09/2021. Please note the similarities of referenced complaints show the first 8 characters KM8JT3AF of the VIN show a direct correlation to manufacturer and engine types. Also note, there is an open unresolved recall # 218 with the potential to cause fires and currently has NO REMEDY available. Recommendations from Hyundai are to park vehicle away from buildings and continue driving even with fire hazard?

While driving down an interstate I accelerated to pass a semi truck. Immediately after passing the truck I took an exit and about halfway off the ramp my car lost all power...no noises or notifications. Had to coast to side of road. Once car was off thr road the engine light oil light and battery light were all lit. I bought a new battery and it did not fix my car. I had a mechanic look at my car and they believe the engine siezed up. The dealership said there is 3 recalls now on my car but engine is not one of them though is probably should be. Was told it would take 3-4 months to get my car in due so many needing repaired. I do not understand how this hasn't been recalled yet. I had my 1 yr old and 2 yr old in the car with me. If my car had quit just 10 seconds earlier we would have likely died. This is not ok for them to keep selling these cars with engine problems. Someone needs to open a lawsuit against hyundai.

My husband had taken my vehicle to work one day. He called me and told me that the car had shut off and wouldn’t restart. He had just turned onto a major highway and was able to pull off to the side of the road. We thought it might have been the key fob, so I brought the other fob with me. Still nothing. The brakes were stiff and the dash would light up, but the engine wouldn’t turn over. We had the car towed back to our home. We replaced the battery and starter, and after doing research, have come to the conclusion there is something in the engine that is causing the engine to not turn over. We believe we’ve narrowed it to the timing chain. Our next step is to take it to the dealership and have it evaluated, but possibly looking to upgrade.

After inspection by the mechanic it was determined that the engine seized. The vehicle is currently at the garage and is available. At the time the engine seized we were on the highway with a speed limit of 70 mph. The vehicle shut off but luckily I was able to pull over safely onto the shoulder. I had my entire family in the vehicle so I definitely feel our safety was at risk. The vehicle has only been inspected by my mechanic. The oil was changed less than two months ago and was changed at regular intervals. There was no warning lights or messages prior to the vehicle losing power. Once it lost power the oil light and engine light came on.

Our 2015 Tucson has the G4NC DOHC GDI engine, which unfortunately isn’t listed in any current engine settlement as of the writing of this complaint. Our engine started to rev at considerably high rpms while driving up hill, followed by a subsequent loss of power and speed. We managed to make it to the top of the hill and pull over, traversing over multiple lanes in front of on-coming semi trucks and other fast moving traffic with our hazards on. Upon pulling over, our engine died. There were no red or amber warning/caution lights on the dash, nor did the check engine light illuminate during the incident. After a few attempts at restarting the engine, we finally got it started and drove it home and brought it to the dealer the next day. They diagnosed it as a “clogged catalytic converter.” Although seemingly a secondary issue, and no further information as to what actually caused the clog in the vehicle inspection report, we reluctantly dished out the $3,200 for the repair of the vehicle we so desperately needed for work. They also installed a “knock-sensor” update. A couple months later… When driving the vehicle to work, the check engine light illuminates and flashes on and off continually. After pulling the vehicle over to a stop and consulting a Hyundai mechanic, I had the vehicle towed to a Hyundai dealership for diagnostics. Turns out the knock sensor update is what caused the engine light to illuminate to “prevent severe engine damage,” and I’m left with a large bill for engine repairs. Will the G4NC engine be investigated by the NHTSA? Will Hyundai honor my drive train warranty? Will Hyundai Corporate ever call me back? Tune in next week…

Driving down the street and the vehicle suddenly shut off in the middle of the roadway. Vehicle would not restart. Engine oil leaking out of tail pipe was noticed when vehicle was being placed on tow truck. Towed to Hyundai. They say seized engine and not covered under warranty due to low oil. No lights came on dash to include low oil or check engine. Only 66,000 miles. Oil last changed less than 4,000 miles. If there was no oil then how is it possible oil leaking from tail pipe. Looked at similar complaints. Appears rods and bearings are braking in these motors. 55 mph road when car suddenly shut off. Could have seriously injured driver. Could have caused serious accident. Hyundai does not stand by their product and warranty.
