VEHICLE SPEED CONTROL

The speedometer in this car is extremely inaccurate and inconsistent with its accuracy. On some occasions, the speedometer can indicate a +-2mph variance at any given speed (good), while other times, the speedometer can indicate a +-6mph variance at any given speed. (bad) The vehicles true speed was verified by GPS speed data and by manually calculating given each individual wheel speed in the car. Both measured speeds confirmed that the vehicles speedometer was off by 5-6mph. No modifications performed to the car. This is a serious safety hazard as the driver is given inaccurate information regarding the actual speed of the vehicle and can lead to accidents.

VEHICLE SPEED CONTROL

I purchased a new 2024 Hyundai Sonata Hybrid Limited on [XXX]. At about 2000 miles I noticed the speedometer of the car and the WAZE app were reporting different speeds. This is an intermittent problem so sometimes the vehicles speedometer and the WAZE app match and other times the vehicles speedometer and the WAZE App disagree. I've repeatedly taken this car to the dealership where I purchased it complaining about the problem and they can't seem to find a problem. Hyundai documented the problem is with WAZE and there's "DELAY" in the signal from the satellite to the WAZE App, even though I've stated my other vehicles speedometers and the vehicle speed reported by WAZE match. Hyundai documented this anomaly is what gives the vehicle it's "UNIQUENESS." Yet they won't resolve this issue. There are several functions in the car that are dependent on the the vehicle's speedometer being correct and when the speedometer is incorrect, these other functions don't work properly either. I've taken the car onto freeways where there are measured mile postings. Sometimes when the speedometer indicates it's at 60 MPH it takes 60 seconds to traverse the mile. Other times, when the speedometer indicates its at 60 MPH it takes 63 seconds to travel the measured mile. it's not just my car, there are many other customers around the United States that are experiencing this problem and I/we can't seem to get Hyundai to address, fix this problem. My personal opinion is this; Hyundai knew about this problem before they put the car out to the market for sale. So Hyundai knowingly sold a defective vehicle, before they sold the first one of these vehicles.

EXTERIOR LIGHTING

I purchased a new 2024 Hyundai Sonata Hybrid Limited in May 2024. At about 3500 miles I noticed the low-beam headlights did not adequately illuminate the road. When driving at night, the low-beams don't illuminate the road signs nor do they adequately have any vertical illumination. When pedestrians are walking on the roadway, the low-beams barley light the calf of a person's leg, but there's no indication of the persons body being illuminated. Using the Hi-Beams, these problems are somewhat resolved. The roadways are better lit, the road signs are better lit and pedestrians are a little more illuminated. I've addressed this with Hyundai, and while there's screw(s) to vertically align the headlamps higher, it seems they are adjusted all the way to the top position. Even if the headlamps could be adjusted vertically, because the headlamps are so recessed under the hood, the hood cuts off any possibility for lights to vertically illuminate people. In my opinion, this is a serious safety issue that's caused by a design flaw and the NTHSA should seriously considering deeming this vehicle unfit for road use at night.

VISIBILITY/WIPER

Fractured windshield from rock strike. Not Hyundai responsiblity. 2 1/2 feet from mirror thru driver view. ISSUE IS: Safelite does not have aftermarket glass. Car is 5 months old. Hyundai says they have zero replacement glass in United States. I can order ($1500), and wait appx 2-3 months. It is illegal both in CA where I reside and federally to drive with fractured windshield. How is it that auto manufacturers are able to not keep safety items reasonably in stock? Covid is long over, I’m tired of hearing “supply chain” excuse. A brief online review shows Kia/Hyundai has had windscreen issues ongoing for years. I’m not even certain that all of my mirror resident safety features are working properly.

AIR BAGS

With a front seat passenger, using the autos seat belt, at the height of 5’ 6” and a 145lbs. The airbag off light will come on, indicating the airbag system has been turned off. This is intermittent and at times the issue can be resolved with pulling the vehicle over. Turning the engine off, asking the passenger to step out of the vehicle (at times on the shoulder of a major interstate), closing the front passenger door. To then reopen the car door, set again in the front passenger seat, secure seat belt and the driver starts the car. Sometimes this will cause the light to go off, indicating the airbag system is on. However, this does NOT always work. During a normal transit the airbag will randomly come on and off.
