Hyundai Tucson electrical problems

Body: my vehicle has experienced a malfunction in the front passenger side door. This door does not open from the outside, regardless of it being unlocked. The failure occurs 99% of attempts to open said door. A repair was made by the dealer I purchased it from, yet the issue returned within a month. First incident: February 2022. Electrical: My vehicle has also experienced malfunctions in all four windows. The initial malfunction occurred in July 2023, when the front driver side window would not go down. Within a week of having the window regulator and motor replaced professionally, the window regulator failed again (would not go back up after being let down)-- with an additional failure in the front passenger side window regulator. The part was replaced for the second time by a different independent service provider. This time, the failure occurred when I inspected the service providers work. The part was reordered and replaced yet again. However; the service provider made me aware that the issue had occured again, shortly after they repaired it and began testing it. The window was blocked off to keep it from sliding down. The issue is now present in all four windows. Each time it is repaired, the window regulator drum gears are stripped within 3-4 uses. - Vehicle is available for inspection upon request. - failure/malfunction was inspected and confirmed by two different independent service providers. - there were no warning lights or signals aside from the initial failure leading to a failure in all four windows.

When I push the brake and push start button at the same time to start the vehicle, it will appear as if it is fully started. It is not until I put the vehicle in reverse that I notice the vehicle is not fully started. This happens on cold or hot starts and anytime of the day sometimes multiple times a day. The battery, malfunction indicator light, immobilizer, and engine oil pressure lights/lamps are on.The service department advisor did say my vehicle replicated but the vehicle was not hooked up to reader at the time. After that no service technician has been able to reproduce the problem. The vehicle has been to the dealership on 3 different occasions and I have provided them with a video.

NHTSA should have a non-official recall warning for Hyundai vehicles that have this software based Safety Defect, which is some models don't have a Passive Engine Immobilizer, and the vehicles can be easily stolen by starting the engine with a USB cord. Thankfully Hyundai(recall) offered a free Anti Theft Software Update, and a steering wheel lock. I checked my VIN number with the Hyundai Dealership in Oregon, and they said my car already received the Anti Theft Software Update. The only reason I knew my 2020 Tucson had this issue, is because State Farm cancelled my insurance a month after I started paying for it. State Farm and Progressive currently deny new policies for vehicles without a Passive Engine Immobilizer. Also State Farm still denied my insurance after I got the software update. Affected Hyundai models from 2011 to 2021 that have standard “turn-key-to-start” ignition systems/without a Passive Engine Immobilizer, are the Accent, Elantra, Santa Fe, Sonata, Tucson, Genesis Coupe, Palisade, Kona, Venue.

The vacuum pump on my 2017 hyundai has a faulty cap resulting in an electrical error to the CAN system. This causes dash lights abs 4wd parking break stability control tpms sensor check engine light to eliminate and the speedometer to not work. All of the systems are not opperating due to the system not being able to communicate. It is illegal and a safety issue to not be able to use the speedometer.

My car has an engine oil leak that has been happening for over a year now since I bought it. I have to change my oil every 2,000 miles because of the leak, when Ive been told this car should be changing its oil for every 7,000 miles. My passenger door no longer opens from the outside once my car is unlocked. I have to put my window down in order to get inside and this is a safety hazard.

the entire computer system shorted out throughout the entire car. It did not let me select above all of what it affected. The entire car malfunction due to the dealer not doing predelivery inspection. They have the vehicle and have not given me a written explanation or reports as to what happened to cause this. This vehicle was defective and dangerous and should not have been sold.

The windows of the 2016 Hyundai Tuscan go down and then the regulator went bad at that exact moment causing the windows to not go up, while driving on the highway. It is available for inspection. On a highway, I was going the speed limit between 65-70 MPH when I put one window down and attempted to put the window back up but I couldn’t. The pressure gets unbalanced and therefore impacts the drivers ears and passengers. I couldn’t even drive without the need to grab my ears because of the pressure. I had to pull over because the window wouldn’t go back up and the other windows wouldn’t go up after trying to balance the pressure in the car. I had to think quick and get on the side of the highway to figure out what happened. My ears wouldn’t stop popping and I couldn’t get back on the highway to get home. I had to drive slow off the following exit because the pain in my ears was so bad. This is a safety issue and isn’t the first time seeing this happen to people. The problem occurred out of nowhere, there were no warning signs and no indication this was going to happen. I confirmed my suspicions by going to a mechanic locally and sought out the issue being the regulator. This cannot be on consumers to repair. Out of all the issues that have been announced about this issue country wide, I’m surprised this has not been brought up before. This happened on 9/18/23 at night going home with my children. They had to cover their ears because of the pressure. I did not call the police or insurance company as I had not been in an accident. That doesn’t not mean this should be taken lightly. Had I not had thought of my kids in my car and thought quickly to pull over, we would have crashed.

Recently the transmission was replaced because the original one was defective. After a couple of weeks, I had turned on the clean air control and it started blowing cold air, so I turned the heater control higher, and the air was even colder. I don't know why this started happening all of a sudden. I'm the type of driver that rarely turns on the heater or air conditioning, I always use the recycle air button that pulls from off the engine and from outside.

When driving the car and stopping at red lights, stop signs, or any other stops in traffic on roads and expressways, the car engine randomly dies and cannot restart between 3 and 10 mins. There is no warning when this is about to happen – the car engine simply dies and dashboard lights come on. There is no response from the car after shifting in Neutral or Park by pressing the start button with foot on brake. After some amount of time, the car will start. There is no warning before this is going to happen. The dealer (Patrick Hyundai) has inspected the car three times and has not been able to reproduce the problem as this happens randomly. They told me on my third visit to not bring the car back as they don't know what the problem is. The first time this happened was 4 months after I owned the car and has happened in excess of 6 times I now fear for my life when I drive this car. I was almost hit twice. I was stopped on a busy main street at a red light when the light turned green and all cars drove away and the truck approaching me assumed I would drive also but couldn’t because the car was stalled in the middle of the road. The truck veered away as last second to avoid my stationary car. The 2nd time was on expressway during traffic when stop and go driving was occurring and my car engine died again. As in previous case, vehicle behind me anticipated I would move forward like other cars but couldn’t and stopped inches from back bumper.
