Engine
109 reports1 crash4 fires
“Without any notice, the crankshaft seized while driving 55 mph on the highway. We were on a highway with one lane in each direction and a shoulder. No warning lights appeared until after the engine failed. We were barely able to coast to the shoulder at the time. The incident blew a baseball size hole in the engine. The vehicle was towed to over 60 miles to Noller Hyundai of Lawrence, Kansas. The repair was paid for under the Hyundai warranty without me providing any maintenance records. The engine is not in our possession for you to inspect, but I'm sure you could reach out to the dealership where it was replaced.”

“The contact owns a 2015 Hyundai Tucson. The contact received notification of NHTSA Campaign Number: 22V056000 (Service Brakes, Hydraulic) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while driving at an undisclosed speed, there was smoke coming from underneath the hood. A chemical odor was detected coming through the air vents causing a burning sensation to the contact's eyes and nose. The contact had to roll down the windows to get relief from the chemical odor. The dealer was made aware of the failure but confirmed that parts were not yet available. The dealer scheduled an upcoming appointment for February 2023. Ray Brandt Hyundai (1700 Westbank Expy, Harvey, LA 70058) and Hyundai Slidell (298 E Howze Beach Rd, Slidell, LA 70461) were also made aware of the failure and scheduled upcoming appointments in 2023.

Perfect...that was november 2023.. 3 days later my car was a little low on gas due to they didn't fill it and I left it be, started it drove about 15 miles and it starts sputtering and almost stalls out. Now here I am in June and beginning of June I hear ticking under hood, thinking it's my oil, I changed it (myself) and here it is 3 weeks later oil keeps burning hot, the oil.pressue light comes on when I brake and off when I give it gas, and I don't have any power what so ever when trying to accelerate and doesn't pick up speed unless I'm going downhill. I have 2 small children and a single mom working 5 days a week, I need this car to work. Please hellllpp me . We were going up a hill and I almost got rear ended because my car didn't have power. Not to mention the driver seat fuse keeps blowing out and the bolt keeps breaking so now I can't fit comfortably while.driving and my seat bounces constantly up and down when going over bumps. This was supposed to be my new beginning family car as this is the newest car I've ever owned and it's become an…”

“On [XXX], my husband and I were driving on [XXX] (Highway) in the slow lane, when the engine shutoff without any Service engine light warning. It was frightening because an tractor trailer was directly behind the car as we lost power. There was no sounds of engine parts knocking or pinging when the problem occurred. The only thing was observed was (two) 2 puffs of smoke seen from the tailpipe, witnessed by my son who was following behind in his vehicle. The vehicle was not able to start after shutdown and had to be towed to my home. We purchased a new battery after assuming battery failure--with no resolve. The vehicle was towed to(two) 2 repair shops with the same conclusion: Seized Engine After checking Open Recalls on my vehicle, I contacted Hyundai to check for assistance. The vehicle is now at the Hyundai dealership in McDonough, Georgia for inspection. I am thankful that my husband and I were not injured or laying in a Morgue after this frighten ordeal on the highway when the Engine suddenly shutoff/Seized.”

“I called Wayne Mazda on 9/7/22 to make an appointment to fix this brake recall and to have my car serviced. I was given an appointment for January 17, 2023, which is 4 months later. I called several times to try and get a current appointment and was denied each time, so I contacted Hyundai and filed a complaint. My case number is 20485596. Also my dashboard light showing low tire pressure stays on, even though AAA came and filled the tires. We are seniors and my husband is in a wheelchair, and I feel 4 months is an unreasonable length of time to wait for a brake (potential fire) recall and service. Any help you can provide with this complaint would be appreciated.”

They told me that it was all good and that they just cleaned up the mass air sensor that was dirty. Brought vehicle home. Mid of Oct driving down highway/55 mph vehicle shut off again on me this time it went into limp mode. Call dealership back and she wanted me to drive it to shop. I stated I’d did not feel comfortable driving it 45 miles in limp mode. Local shop Looked at it discussed with dealership. I finally spoke to the shop they gave me the information of the codes. Dealership texted me not phone call told me all about the code It was pulling and recommended that I take it to a Hyundai dealership as there is a service campaign on the vehicle. Dealership sent bank a copy of the service campaign. It states as required by federal law dealers must not place vehicle into customers use until campaign and all open recalls performed on vehicle. Campaign states it is a safety action. Campaign…”
