2023 Hyundai Tucson Other Problems

While driving on the highway, your moonroof glass spontaneously shattered and fell into the car, creating a serious distraction and safety hazard. You were at risk of physical injury from the falling glass and debris. The failure occurred with no warning beforehand, and you're aware of similar reports from other Hyundai Tucson owners. Fixing this will require inspection of the moonroof assembly and likely replacement of the glass panel and any associated tracks or seals.

While driving at 40 mph in dusk conditions with adequate following distance, you braked when the vehicle ahead began slowing for a red light. Your car continued forward despite your braking effort and appeared to accelerate instead, causing a collision. Your vehicle's forward collision warning system did not alert you or attempt to brake automatically, even though you were approaching the car ahead. The repair bill came to $6,645.90. You should have a mechanic inspect your braking system, forward collision avoidance sensors, and throttle control to determine why the brakes didn't respond and the car appeared to surge forward.

Your sunroof suddenly shattered while driving, creating a loud explosion-like sound followed by glass breaking. The unexpected noise caused you to swerve, creating a safety hazard for your passengers and other vehicles nearby. The sunroof failed with no prior warnings or messages, and the dealership confirmed they've never seen this issue before.

Your 2023 Hyundai Tucson's wiring insulation may be damaged by rodents chewing through the soy-based and plant-derived biodegradable materials used in the wire housing. This has resulted in thousands of dollars in repair costs that are often not covered by warranty or insurance. The owner believes this is a design defect rather than owner negligence and is requesting investigation into whether this constitutes a safety issue warranting a recall. Repairs would involve replacing damaged wiring harnesses and wire insulation with rodent-resistant alternatives.

Your horn has failed twice—once at 67,000 miles and again at 100,000 miles—requiring two separate replacements at the dealership. You've experienced situations where you needed the horn to alert other drivers to unsafe lane changes, but it didn't work. The dealership mentioned many customers have reported similar horn failures and suggested you keep receipts for potential reimbursement, though no recall is currently in place.

Your car has twice accelerated on its own while you were stopped or idling in traffic, with the engine revving to nearly 8,000 RPM and lurching forward before you could brake. Stopping and restarting the car resolved the issue both times. No warning lights appeared on your dashboard, and the dealership hasn't been able to reproduce the problem during testing.

Your 2023 Tucson's windshield has developed pitting, chips, and cracks from normal highway driving without exposure to gravel or dirt roads. When a repair shop tried to fix one of the larger chips, the windshield cracked further, suggesting the glass may be defective or unusually fragile. The fine pitting across the windshield has reduced visibility noticeably. You may need to have the windshield replaced with a new one to restore visibility and safety.

Your horn stopped working completely after use during rainy highway driving. The dealer confirmed this is a known issue with your vehicle and ordered replacement horns, which took longer than expected to arrive. The service technician indicated Hyundai is aware this is a safety concern. The repair involves replacing the horn assembly with a redesigned unit.

Your Bluetooth hands-free phone button isn't working. The dealership told you that a software update to fix it won't be available until December, leaving you unable to safely use your phone while driving for the next few months. The fix will require a software update to be installed at a dealership once it becomes available.

UNKNOWN - was parking in a spot and car accelerated uncommanded, stepped on the brakes and car did not stop. It stopped with parking sign cement post.

Horn stopped working even the fuse is fine still horn not working . Not panic alarm sound either.

2023 Tuscon Limited Gas - Multiple instances on Vehicle Forward collision warning system activating with alarms noted but no activation of emergency braking while sitting at stop light with cars in front and back that are not moving. Radio system going to show surround view and in some cases only front view even though at stop light. Biggest issue this weekend while taking a curve while merging onto another freeway the emergency braking system activated for no reason. First time occurrence. No one beside me or in front of me for some distance but did have someone behind me. It was a quick activation of the brakes and then release, I would say 1-2 second engagement. If had been longer and brought me to stop would of been an accident. I am taking the car to Westlake Hyundai to investigate this week and will report. Also having dealer investigate premature driver seat excessive wear. Car has 15.5K miles on it. I am concerned as this car is exhibiting same issues that my wife's 2018 Tuscon had that ended-up being successfully lemon lawed. I am also seeing way to many similar complaints and Hyundai needs to figure out what is going on with their emergency front collision sensing system and issue a fix or recall.

Failure to accelerate. While entering Route 95 from on ramp traveling at about 40 miles the car failed to accelerate. Gas pedal revved engine but failed to accelerate and slowed. Safety of myself and others in grave risk as I was trying to merge into traffic that was traveling at 65 miles per hour. I contacted dealer and was told appointment was not available for weeks and they never heard of the problem. I will bring auto into dealership and leave it with them as it is clearly unsafe to drive. No warning light on dash or engine light problem was present.

Upon closing the driver’s side door, the panoramic sunroof exploded. The car is currently at the dealership where it was purchased. It is available for inspection. Safety……Any occupants within the vehicle would have been exposed to the shards of glass if the sunshade was open! The dealer stated that Hyundai has approved the replacement of the exploded sunroof glass and the cleaning of the glass remnants inside the car. The was no warning or symptoms prior to this incident. We requested a loaner vehicle but as of today we have not received one. Completion date stated 1 week..order and installation. The rounded upwards photo of the sunroof glass, the stress fractures at the front and rear of the glass as well as the inward bending of the front sunroof corners gives every indication of an upward movement of the glass from within the car. It was not damaged by any objects external to the vehicle. There are many similar incidents cited on the internet

The trim on the driver's side rear door flew off while traveling at approximately 65 miles per hour. Luckly no one was behind me. I was able to retrieve the trim piece from the highway and it was determined to have been placed improperly on the car. The trim was not able to be replaced due to damage when it was run over by several vehicles. The warranty says it's covered but the trim has been on back order for a month.

Driving down the freeway at normal speeds and my panoramic sunroof literally just exploded, raining tempered glass all over the interior of the vehicle while I was driving. No evidence that it was caused by any road debris, objects, nor falling objects from the sky. I wasn’t driving under a bridge and no cars/trucks were immediately next to me nor in front of me. Traffic was flowing at normal speed. I wasn’t injured but was certainly startled and distracted for a moment to gauge what had just happened. The dealer is looking into it. Claims it could have been caused by a rock. That seems to defy the law of physics and the glass actually look like it bowed from the inside out as if too much pressure was being applied to the glass. Searches online seem to point to several class action lawsuits and plenty of reports of similar exploding sunroofs!

Trunk door opens by itself. This has happened after exiting vehicle at least 3 times when vehicle is parked. Has not happened while moving

I was driving on I95 and all of sudden the truck started sputtering and shut off. I turned off and back on , it would not go. Then the engine light came on. There was also smoke coming from the tail pipe when I tried again to start it. Back in December 2022, I was driving and the truck cut off and would not start at all. It was diagnosed as the Ignition coil being the problem. This horrible, both times could have been worse because of it cutting off while driving.
