Desconocido.

Hello, thanks for reviewing. I recently bought a brand new Hyundai (VIN provided) and the speedometer intermittently is inaccurate. Maybe 50% of the time, which I would argue is less safe since I can’t reliably tell what my speed is. When it is an issue, it’s worse the faster I drive. It breaks the 10% threshold I’ve read about around 30mph, where it will say 26mph. I brought it to the Hyundai dealership and they claimed they couldn’t replicate the issue so they won’t fix it - but it’s intermittent and I have picture / video proof from multiple dates. I used various speed sources to be sure. I found some Hyundai forums online where many others have the same issue. The speedometer is an important safety feature, not to mention other dependent features, like cruise control. Happy to provide proof by request.

Paint the paint issue with Hyundai is ridiculous. I have a 2016 Hyundai Sonata. No matter if I’m driving, going through a car wash, or just sitting in the yard. It’s absolutely ridiculous. Corporate and a lawyer has been contacted and the said there wasn’t anything they could do. There is thousands of cars that look the same or worse than mine.

Vehicle’s front collision sensor popped up on dash, vehicle lost all power. Almost was hit by a group a semi trucks hauling a wide load that wouldn’t have been able to stop in time. This is the 3rd time it has happened in a week and a half.

Hev warning turn off engine sign while driving on the interstate my car lost power and the car behind me had to suddenly move over this is very unsafe while driving down the interstate.

Found me driving on I 75 and I put the cruise control at 70 miles, instead of maintaining the speed at 70miles the vehicle accelerated to more than 90 miles per hour I had to quickly put my foot on the brake otherwise I could have an accident with the vehicle from the front, after all this happened, I felt the car was losing speed, I tried to accelerate but it did not go over 60 miles per hour. I took it to the mechanic and they did not detect anything in the vehicle's computer. This vehicle also turns off at times when you are driving and it turns off it also spend too much oil motor , I started looking for information on this model of car and I see that there are more than 550 people who have the same problem as me, this is an unsafe vehicle for the road.

Complete engine failure while driving. Car completely shut off and will not restart. It did not give any warnings prior to happening. Also cruise control stopped working months prior to this engine failure. Took to mechanic and he stated there is recalls on this vehicle and need to turn it in. I have also received mail stating the same about recalls.

I first noticed an issue with the voice resignation which also is effecting the messages navigation phone and just recently the lane assist and radar. For 2 weeks I have tried to address this with Hyundai customer service with no proper response the dealer service I stating the computer head is at fault but they have no idea when they will get one from Hyundai. I know the service people will be keeping the car for week to resolve this since the whole dashboard will be removed. I was told a representative from hyundi will be contacting me on the 5th wich I doubt will happen because when I had a problem in April 2023 I was told the same thing I had the phone nearby all day and no one ever called and I am assuming the same will happen on the 5th. This is not a dealer or service dept issue it's a hyundi problem and I am reluctant to use any of the assisted driving or rely on the safety components that this car is individually installed with.

Warning light for airbag continues to stay on , and cruise control does not work at all.

My Sonata uses oil about a quart every 1000 miles. The acceleration is weak and there's no warning lights on in the dash. The lifters will start chattering and I'll stop and put a quart to a quart and a half in it. The cruise control alot of times will not work and when it does a lot of times you have to mash the buttons hard and several times. My Sonata is ready to be inspected at anytime.

On a highway cruising at 70mph with the acc (adaptive cruise control ) on and following distance set at max a car from another lane turned into my lane and then continued to an off ramp. My car initially braked and then downshifted from 8th to maybe 4th and accelerated hard - scaring me and my passengers. I did add to the actions of the car by pressing the following distance button on the steering wheel a few times. I had owned a 2016 Sonata with acc and drove over 100k miles with acc operating. That is why I pressed the following distance button - to lessen the actions of the car when the car entered my lane. The 2016 also had a acc setting of fast, normal, & slow (I used normal). The 2023 has no acc setting. I did complain to my dealer and he said this was normal and nothing happened. I feel this is dangerous so reported it to Hyundai customer service. They told me to go to my dealer.

The bluelink subscription service for my Hyundai Sonata includes a feature to see the diagnostic codes my car has or has had. Attached is a document with all of the dtcs my car has reported since I purchased it new in November of 2021. There are 15 stored codes (not active) but they are still concerning to me because they have appeared from before the car was built to about 1000 miles after I purchased it. 5 codes are for the lane keep assist system, 1 for the electronic stability control, 5 for Smart cruise control, and 4 for the tire pressure monitoring system. Three of the codes occurred after I purchased the vehicle with absolutely no warning or indication of any fault regarding the lkas system.

Manufacturer has refused to return my calls. Dragged me down there for an appointment, made me wait. Just to tell me they didn't order the specific part even though I made the appointment months in advanced. . . . And to call back in a week. That was September (6 months ago). I called, multiple times. Either I get no answer, voice mail, hung up on, laughed at or told that they will urgently call me right back. All to no call back . I've reached out on social media, email, called managers, no one has followed up, horne Hyundai az is a joke! and so is the surrounding certified dealers. No one has reached out and I've tried all outlets to dealers (somewhat) near me. No one finds this serious so if I get injured on the campus much longer and I will regret it.

There are multiple issue with this car since last a year or more. ( picture attached) * at times computer flashes below message . . " Hyundai system warning safety stop do not drive" * steering lock up * while driving a screeching sound and then it goes away. We received the recall notice and my daughter jeranica took it to the Hyundai dealer for repair. They charged us $900 mentioning the issue is with belt & assembly and engine is ok. We informed then of all the above issue. Even after repairing the above we still have the same issue with the car. It look like Hyundai dealer are using this opportunity to rip-off the customer instead of actually fixing the issue. We still have above issue with, car computer asking us to stop on highway and steering lockup, dealer does not seem to be interested in fixing the issue. At one time he mentioned we have 114k mileage on the car and the life of engine is finish.

Air bag light on all steering controls not working.

I bought my vehicle from a local dealership a week ago. The horn and none of the features on the steering wheel work. The front panel of the steering wheel feels lose. I also smell gas often and my left muffler smokes and I sometimes smell burning rubber. Navigation does not work as it should and my xm features don't work because of a bad xm antenna (shark fin. ) there is vibration in the steering when braking. My tire pressure light blinks and then stays on. The key doesn't operate the locks sometimes.

The vehicle slows down on its own and will not allow me to rev up even when pressing the gas pedal down. Also the light for traction control turns on and the brake lights stay on all day and all night whether the car is on or off.

When trying to set my cruise control a message pops up on my dash saying scc conditions not met.

This is a major issue thousands are having with this model 2014 Sonata. When using the blinker, it causes the headlights to completely shut off while driving. Soon as the blinker turns off it kills the headlights. Extremely dangerous and Hyundai seems to be ignoring this issue and pretending they're not hearing of it often. I've had to pull over many times until the lights come back on. Seems to be an issue in the steering column. Cruise control also decides when it wants to work. Sometimes on startup it works, sometimes it doesn�t. I believe it has to do when the car is started. Something odd electrically with these cars. But the blinker/headlight issue is causing wrecks. This is wildly dangerous.

Engine stopped running while driving.

Gases from the dashboard heating cause a film to form between the windshield and the camera. Because of this, in heavy direct sunlight, lane keep assist toggles on and off without warning causing unintended lane departures with out warning. Also, when using Smart cruise control, the vehicle slows to a stop but may continue moving slowly even after displaying the press gas to continue screen. The auto hold light does not illuminate.
