Two times while stopped or idling behind a car in traffic, my Hyundai Tucson 2023 has started accelerating on its own with the RPM increasing to nearly 8000 and lurching forward before I was able to apply brakes. Stop the car and restart. I have seen this described on other car message boards and hope the NHTSA will take this seriously. The dealership is not being helpful and claims they cannot reproduce it and it has not caused any onboard diagnostic codes.

I was backing out of my driveway, which is on a busy street. I waited for the traffic to clear. I backed out onto the main road, which I thought was completely clear, but a car came behind me and I smacked right into him. There was no beeping from my car, and the automatic braking system did not engage at all. The rear of my car, particularly the driver's side, was severely damaged. The other car's passenger front door was badly damaged. The side curtain airbag on their car deployed and their vehicle (Volvo station wagon) was not driveable. The emergency braking system frequently engages unexpectedly when I back out of my driveway, even when there is no hazard. The unexpected braking is oftentimes dangerous. However, this time, when I needed it, it did not engage. An outside diagnostic inspection was done on the vehicle, and showed "no event." If you saw the cars involved in the accident, it is clear there was a significant "event."

My 2023 Hyundai Tucson’s windshield has developed excessive pitting, multiple chips, and cracks despite only normal highway driving. I do not drive on gravel or dirt roads, yet the glass shows abnormal wear far beyond what would be expected for a vehicle this new. One of the larger chips was repaired by Safelite, and during the repair the windshield cracked further, suggesting the glass is unusually weak or defective. Visibility has become noticeably compromised due to the fine pitting across the entire windshield. Based on the number of similar complaints from other Tucson owners, this appears to be a recurring safety issue with Hyundai windshields.

As I was parking my car in a parking spot going about 5 miles or less. My car surged forward at a very accelerated speed, and I ended up running into a brushed and a metal fence, which is what stopped me. There were no warnings that went off on my car. No emergency brakes, nothing.

2023 Hyundai Tuscon - Very Low Milage approx 6500 Miles - while in a parking lot, The rear passenger Carrier ARM which holds the Control arm fully cracked causing the Control arm to fall off. This product failure is unprecedented as it was a total part manufacture failure. NO impact or under carriage damage was found, even upon Dealer inspection. I as the driver of the vehicle confirm that No impact, accident occurred, and luckily I was not on a highway when it occurred. This was caused ONLY as a result of Product Failure. My concern is that this may occur on the other wheel(s) as a product failure is often NOT a one- product issue, but usually a batch failure. So I am concerned for my safety and the safety of others on the road with this vehicle and product part. Another concern - this vehicle was manufactured during the covid era, and I am concerned about product failures as parts were difficult to get and may have been sourced without proper testing during this time). Kindly advise me on your findings, and if there is an inspection that can be performed to assure me that the car is safe.

After using horn on rainy highway driving it stopped working completely. Called dealer with issue and scheduled appointment. After two day they said it is a know issue and horns will take 2-3 business days to order. Took 5. Getting horns replaced today but told by service tech that this is a known safety issue to Hyundai. Horns are a basic piece of equipment. Should be recalled and better designed.

My 2023 Hyundai Tuscon has 36000 miles. Started running rough with a slight noise. First noticed on Wed [XXX]. On Thursday [XXX] I went to start my car and it stalled. Finally after letting it sit a few minutes it started but only to have the SGI light flash yellow and stay yellow for the remainder of the drive. That day I made an appt at my local Hyundai Dealership in Brandon Florida. They kept my car. Fast forward, Monday September 15th I was notified that the car had lost a significant amount of oil. Car was inspected and free of any leaks. Tech stated because of the low oil & oil pressure the battery life was significantly impacted. I would need an oil change & new battery. Upon arriving back I came across an article stating that excessive oil consumption is common among these vehicles and the dealer wasn't even going to notify me of this issue. They were not honest and I want to file a formal complaint knowing that this is well known issue. I feel unsafe driving my children around and am upset that a recall has not been issued to fix this.

On [XXX], while driving a 2023 Hyundai TUCSON SEL, the steering wheel suddenly and completely detached from the steering column and ended up in the driver's lap. This sudden and absolute loss of steering control is a catastrophic failure of a primary safety system that placed the driver's life and potentially the lives of others in immediate and extreme peril. It was only due to sheer luck that the vehicle was brought to a stop without an accident or injury. Following the incident, due to fear and anxiety, the driver is now in treatment and has been unable to work. The vehicle was transported to Ron Marhofer Hyundai on the same day. The following day, the driver was met with a profound lack of respect and professionalism from the service advisor, Declan McCready. The driver and her mother were implicitly told they did not know what they were talking about and were treated with a profound lack of respect. The service advisor initially asserted there was no warranty coverage for the issue and that it would cost nearly $500.00 to fix. He also claimed his entire shop of mechanics looked at the car and found nothing was broken. However, the very next day, the dealership abruptly reversed their diagnosis and instructed the driver to get a rental car, stating they would now be fixing the vehicle under warranty. The repair order confirms the technician's findings: "verified concern steering column separated stopped bracket bent and separated replaced column housing operating normal". The vehicle had 14,479 miles at the time of the failure. There were no prior warnings or symptoms before the incident.

I leased a 2023 Hyundai Tucson AWD, and approximately four months after leasing, I began experiencing vibration and shaking when braking, especially at higher speeds and downhill. I brought the issue to a dealership, and while replacing the brake pads temporarily resolved the problem, I am concerned it will return, as many other Tucson owners have reported similar recurring issues even after rotor or pad replacement. This raises concerns about a potential underlying defect in the braking system that may not have been properly addressed. The issue poses a serious safety risk due to reduced control during braking, and I am documenting this in case it recurs. No warning lights appeared, but the problem was physically noticeable and confirmed by the service center. The vehicle is available for inspection upon request. I have a video i can send as per request i am not able to attach.

my 2023 Hyundai Tucson has had the horn replaced twice. the technician indicated this is a common problem due to the location of the horn its susceptible to water damage rendering it useless. The horn is something rarely used and we were not aware it did not work until we tried to use it to alert a car entering our lane of traffic!

For the second time in a year, I was pulling into a parking space and when I applied the brake, the car accelerated, seemed to be airborne and lurched forward. Though I firmly had my foot on the break, it would not stop until it hit a brick post about three feet away. This exact same scenario happened in July of last year. Then, I hit a stand of shrubs. Someone said, your foot must have slipped off the break and hit the accelerator. I said, “I don’t think so.” Yet, I took the blame for the accident, for I could not believe it was a car malfunction, nothing close to this had happened to me since I owned the car. Everything was the same in the last crash as in the first. This time, as soon as the car accelerated, I checked, and my foot was firmly on the break. There is definitely a malfunction in the car. The black.box Should be recovered and read by someone not associated with Hyundai. I checked on Hyundai Tucson Owners’ group on Facebook, and my incident has been reported by others.

I previously leased my vehicle from Rick Case Hyundai in April 2023, In November i started having issues with my vehicle as i moved to Colorado. My whole vehicle starts to uncontrollably shake going 25 mph and over. Since highway speed limit is 65 that is where i struggle the most with driving and that is the most endangering as well. I have to pump my breaks and hope they don't stop working. I have taken my car to get a diagnostic multiple times at different dealerships and each time i went to another dealership they advised a different problem I can send an email or mail with all attachments of diagnostic reports from Hyundai dealership. Each dealership advised one of these problems, engine, brakes, rotors, tires, etc, although the vehicle was a few months old! I reported lemon l to Hyundai Customer service with 2 different attempts and they denied my lemon law and advised i should pay for anything not under warranty. Although the vehicle has a manufacture defect i will be continuing to attempt different dealerships to help my cause since i am endangering myself and everyone around me. I have done enough research to know i am not the only person with this problem and this should be a recall defect. I need a solution so i can drive in the state i live in ,Colorado, and not be scared for my life that my car will stop working at some point.

While on the road, the sunroof just shattered completely. In this instance, nobody was hurt as the cover below the sunroof was open and that caught all the glass pieces. The car is hardly 2 year old and warranty covered the repairs. The complaint is that Hyundai never gave a clear answer as to why this happened and what can be done to prevent it. There is no consideration of the passengers getting hurt and startled by this incident. Also no consideration for the time it took for the repairs, the dealership never gave a loaner and we didn’t know we could rent it and Hyundai would reimburse. I feel Hyundai cannot just say sorry and move on as there has to be a reason for this and we pay extra for having a sunroof. I am not satisfied with Hyundai’s method of dealing with customers who suffered bear of their own manufacturing.

Driving on the highway when my car stopped accelerating when pressing down on the gas pedal. It was very risky to be driving on the highway without the ability to accelerate so we put our hazard lights on while we got out the highway ay the nearest exit and parked the car in a nearby parking lot. We were stranded about 100 miles away from home and had to have the car towed back home. Dealership confirmed that it was the fuel injector that was the issue and has been a known common issue for this type of vehicle.

Approximately 2-3 months ago, the horn had failed. This was reported to the dealer and covered under warranty. During the service the dealer advised that this issue was due to a faulty electrical contact and was a “known issue with the supplier of the horn”. Because of this, Hyundai extended the warranty period on the horn. Now, the horn had failed a second time and was discovered during a safety hazard in which I needed to alert another driver. This had the potential to cause serious injury but was avoided.

2023 Hyundai Tucson with just over 14,000 miles failed to accelerate. After completing a right turn the vehicle seemed like it went into neutral. A green warning light appeared stating limit 20 mph. I now know this is “limp mode”. Turning the vehicle off and back on seemed to resolve the issue. The vehicle was towed to the dealer. They found nothing wrong. I was told to take a picture of the warning next time. I was fortunate to not have caused an accident. This is incredibly dangerous.
