The vehicle's fuel gauge (type C) does not accurately adjust for changes in the amount of gas in a timely manner. It normally takes 2-3 days for the gauge to move to full tank even though it is full. Same problem from 1/4 to 1/2 tank, etc. For example, I noticed the panel said I had 11 miles to empty on Friday. The gas gauge showed otherwise. I wasn't near my usual fill station, so I put 5 gallons of gas in the car. It is now Wednesday (5 days later). The gas gauge moved slightly yesterday to almost 1/4 tank, but the fuel tank warning went from 11 to 0 miles left to empty (see attachment). I drove on the highway each day and in the city. I purchased this car July 2020 with a full tank. This problem became evident in Aug 2020. After refilling the tank, the reader showed 111 miles to empty. I informed Hyundai agent of the issue, who had no idea why this was happening. The guage and fuel tank reader finally adjusted after about 3 days. I had 449 miles on the car at that time. I now have over 4,000 with same problem. Apparently, something is faulty, but I don't know what. Auto dealer is baffled. This issue could result in a real fuel shortage while traveling with no gas station nearby.

Engine block became infested with rats/mice overnight. I believe this was the result of soy-based components used by Hyundai. No other cars on my block had this problem (I was able to survey the vehicle owners because we all were there waiting for street cleaning to occur.) it seems obvious that the rats/mice were attracted by the materials used by Hyundai and anecdotal reports suggest this is a chronic problem among many car manufacturers, but especially ones that use soy based components such as Hyundai, Land Rover, and Honda.

The car while I'm driving sometimes the car is unstable also when I turn on the car and I prepare to put it on drive the car apply the emergency brakes by itself. The emergency brake light is on and there is no way to remove it, I have to turn the car on and off continually until finally the car removes the brakes. I was driving on the highway and on the street and while I was doing so the car put on the brakes by itself. One to two months ago I took the car to the dealer and I told them about it but they said that the care needs 2 updates, apparently the car has two recalls. 6 hours later after the update the care wasn't working properly and they kept the car for 3 to 4 days, I got a loner by then. Last week Wednesday 08/05/2020 I took the car again to report the problem and I was told the care would be ready in 5 hours but after 5 hours it wasn't. since I didn't feel safe in the car I told them to keep the car and give me a loaner because the car is going to take one week to fix because they have to order parts, they want to keep the car but they didn't want to give me a loaner. I contact Hyundai corporate to report this incident because it is twice already, and I was told that someone would be in contact with me in the next 48 hours. I missed the call and I have been trying to call to get in contact with them again to fix the problem but every time I call they come with another excuse. The case manager in charge of the case is garrison and the case number 17216875.

Rear doors retain water every time it rains. When you open the rear doors water drains out of the car. Brought car to Hyundai dealership who verified the problem and confirmed the problem with other new cars on their lot, on April 21, 2020. Dealership contacted Hyundai corporate for guidance and there has been no response to date.

When it rains water gets inside the doors while parked. Especially the back doors. If it rains hard a cup full of water will come out the door upon opening. I've been told it's a design flaw. I've had it looked at twice and it's still not fixed. Customer service can't have someone come out and look and it because of the virus, so there's nothing that they can do.
