2017 Hyundai Tucson Fuel Cell fuel/propulsion system problems

“My car has been burning oil for over a year. there is no leak. I have been putting three quarts in every 4 to 6 weeks. I have now replaced two coil packs and the spark plugs. my engine light is on because it said 3 and 4 was misfiring so i recently replaced those coil packs and now it said spark plug and i replaced it again as well. so the engine light coming on and what it says the problem is is wrong. now when i push the gas it is knocking or missing. not sure how to describe it. no one has looked at it other than a friend that is a mechanic and he says its probably the engine because this kind of car has these problems.”

“1. After driving the car and turning it off, I get a loud bang coming from a gas tank. 2. Sometimes when making a hard right or left turn steering wheel vibrates, and the warning light for all wheel drive system comes on. When I turn the car off and restart it, it goes away. 3. After software installs due to recalls, when I accelerate my radio occasionally shuts off on its own, and then we’ll come back on on its own. 4. After turning the car off when I restart it occasionally the clock in calendar revert to 00:00 for the time and the date resets to 1/1/20.”

“Greetings, I have had issues with the Hyundai Tucson 2017 I own for many months. Issues include among others an abnormal knocking noise from the engine, reduced engine power and/or hesitation, burning smell, oil leaking, and smoke coming out of the engine, misfires, and other issues. It happened many times on the highway and almost caused accidents and the last time it happened, the vehicle was towed, and recently the smoke coming from the engine forced me to pull over. I reported the issue to the dealer but they didn't recall or address the issue. The car has been maintained properly over time and now I fear for my life. It is totally unfair that about 100k of this brand have been recalled for the same issue, in my case it is just after I finished to pay in full the vehicle. I seek your support to have it addressed for safety”

“In June of 2023 at around 79,000 miles. I was driving on the highway and had a sudden loss in acceleration and would not go above 65 mph. During the inspection, the dealership ran the vehicle through 3 tests of oil consumption and it failed 2 out of 3 which did not result in a replacement of the oil pan system. My car continues to burn through oil at an increased rate (every 3000 miles). I know because the dip stick is completely dry when checking it. In July of 2024 at around 84,000 miles, while driving on the interstate, I experienced a loss in acceleration again. My Tucson would not accelerate over 65mph. I took it into the dealership and they found that my catalytic converter needed to be replaced. The replacement was estimated to cost around $5000. For each incident, there were no warning lamps that illuminated on the dash. The oil light did not come on nor did the engine light come on.”

“Four days while driving on streets and freeways in Oklahoma City My 2017 Hyundai Tucson turned off and stalled. Lots of lights came on. Luckily I was able to get out of traffic without getting rear ended. I took the suv to local Hyundai dealer and they couldn’t find the problem. The second time I took it to the dealer they replaced sensor crankshaft to clear lights that were coming on. Paid $209.27 for multi point inspection and paid $412.62 for second repair. I’m frustrated because I was without transportation for 4 days. Dealerships did not offer a car for me to drive.”

“Car has 125,000 mi on it. This will be the 3rd catalytic converter in 2 years. Second one was March of 2022. I have excessive oil consumption (1QT every other week). Which I believe causes the exhaust system to clog. It’s an engine flaw design I believe. The issues isn’t the converter but the oil consumption contributing to the clogging. The vehicle actually had complete engine failure while I was driving on the interstate Dec 23, 2023 driving at 70 miles an hour! It was caused by the clogged converter! I could have died! Thank you.”
