Filed Feb 12, 2025 · Acceleration · MA · crash

As I was pulling up to a gas pump, my car suddenly accelerated. Applied the brakes to stop but it kept accelerating. My choices were to hit the car in front of me or a snow bank. I chose the snow bank. Tons of damage to my car. Don’t have that info yet, though.

I was commuting home from work when suddenly there was smoke coming from under the hood and the vehicle completely stopped working in the middle of the road. It would not accelerate and I had to get help to move it into a parking lot. I had to get it towed to my home. The car will not start. If we turn the key to try to start it, the engine starts smoking.

I am the owner of a 2014 Hyundai Sonata. That car is 8 years old and has 69K miles on it. At no time did Hyundai Motor Company notify that my car was impacted by an engine failure recall. On November 10, 2022 the car was being driven. At no time did it give any potential warning, instead the car fully stopped while in motion at 25 mph. There was no warning, no lights appeared on the dashboard until the car had stalled itself out. When I called the local dealer where the car was purchased, I was promised a call back. That call never came. I was able to contact someone at corporate who did confirm the vin number of my car is on an engine recall. I was told to contact a local dealer to find someone to replace the recall alerts. Again the local SURESKY dealer cannot help me. After spending 4 hours on the phone, I was able to connect with someone in a service department who indicated that the return volume of these car is so extensive that they are backlogged 3 to 4 more. I would encourage all users of this car to immediately end use of it. I would encourage all users to look into local LEMON laws. This entire recall was handled completely wrong by Hyundai Corporate who. Nobody can answer questions, they can only pass you around. The company should be investigated for consumer fraud at the state and federal level. The company should be investigated for proper accounting, proper tax reporting, for the recall.

January 29th my check engine light came on and I was not able to go no more than 40mph. there is a knocking noise coming from the engine. took it to autozone and the code was P1326. Now when I start it up it has a smoking smell to it and the knocking is getting louder. I have not driven my vehicle since January 29 2022 The knocking noise first started January 24th. I see there is a recall for this issue with other Hyundai vehicles but for some reason it is not showed for my vin. One Hyundai dealership told me they can not look at my vehicle until march1

The check engine light illuminated intermittently at 92k miles, then the engine started making noises intermittently, and then the vehicle was slow to accelerate intermittently. The knock sensor software upgrade had previously been installed. The synthetic oil had been changed at 82k and 86k. South point hyundai changed the oil, replaced the battery and turbocharger at 92381 miles. Around 93246 miles the intermittent engine noises and intermittent no acceleration and slow acceleration are back, and the check engine light is not illuminating. Returned my sonata to south point hyundai who reports the engine is bad, but there are no diagnostic error codes, and they are waiting to hear back from hyundai on how to proceed. Hence, the knock sensor software update is not a corrective action for detecting engine failure, alerting drivers to engine failure. The knock sensor software update is not an effective screen for engine defects. The engine noises occur when the vehicle is stationary, in motion, on a city street, and on a highway.

Once my sonata hybrid reached 105000 miles it has reflected the exact issues of the other 2.4l engines. Loud knocking, lack of acceleration above a certain RPM and unable to go above 60 MPH. The car is currently sitting in the drive way since it sounds like a rod is about to rip through it. The oil light comes on but only when turning. We have been denied since this VIN is not included in current recalls. All recommended maintenance has been done since we bought it brand new.

As I was driving on the highway at 75 miles an hour in severe traffic car started to make noise and blink check brake. Then it started to slow down to around 10 miles an hour and new message was hybrid system warning do not drive. If I was not on the end lane I would have been in an accident. My kids and partner are traumatized. Very dangerous design needs to be looked at.

2014 hyundai sonata was dropped off to nearby hyundai dealership for scheduled recall appointment campaigns 180, 953, 160, 162, and 946 on 04/24/2019. Dealership communicated to me all recall inspections were made, and no further repairs or replacements to the car was needed at approximately 11:30am on 04/24/2019. Car was then picked up through the sales department at my earliest convenience on 04/25/2019 at approximately 7:00pm. After driving 9 miles on a 55mph street, my car lost immediate acceleration/power causing the speed to reduce without warning, and without brake lights activated (witness to this is the individual who drove me to the dealership to pick up the car, and was currently driving behind me at the time of the incident). After immediate loss of acceleration/power (the car was moving at 55mph), the check engine light began blinking. The car was immediately moved off the road, and a burning smell was detected after removing myself from the vehicle. As the service department was unavailable, the sales department from who gave me my car we're unable to properly assist me with receiving a tow back to the dealership, and provide me with a loaner car for the cars inability to be driven. At approximately 8:50pm, a tow arrived to take the vehicle back to hyundai's dealership in which the recall inspections and campaigns were performed. Dealership approved a rental for the following day, yet unavailable/unable to be approved until the service department re-opened. Currently, the dealership has me in a rental car through enterprise, covering the cost except for $1.00 a day (which is to be paid by me). More so, as this is not my car, an additional coverage charge of $9.00 per day was required to insure me coverage in the event the rental is involved in an unexpected accident. As of 04/28/2019, I am waiting to hear an update from the dealership about my car.
