“There is a definite KNOWN problem with the transmissions in all 2018 Hyundai Tucsons and maybe other model years as well. This is well documented via the Internet by the number of articles concerning this ongoing problem! This problem seems to have been unresolved over a pretty long period of time now! It is most definitely a safety issue and should be addressed. When issue happens it leaves the vehicle at the mercy of surrounding traffic! It definitely requires your consideration and your looking into! Search the internet concerning this transmission failure problem.... Why has this NOT been addressed prior to or long before now?”Owner report · Power Train · Aug 2026
“The engine has been consuming oil, where we were adding at least a quart of oil between oil changes. We noticed the vehicle would shake like it was going to die while idling at a stop light or in a drive through. Recently my husband was driving home from work on a busy highway and the vehicles check engine light started blinking on and off. He pulled over and had the vehicle towed. The oil consumption made the vehicle throw a rod and damage the engine. Now we are needing to replace the engine.”Owner report · Engine · Jun 2026

“On June 5, 2026, driver was on I25, when driver heard engine making a winding and weird noise. Vehicle immediately went from 60 mph to 40 mph. It was extremely dangerous and driver barely evaded a collusion with several other vehicles. A check oil and engine light came on. Towed back to same Hyundai dealership. They claim engine needs replaced and needs maintenance kit. Total cost $16,892.87. Note: prior to, in January 2026 the transmission and differential were replaced. Was told there were no other issues (same Hyundai dealership).”Owner report · Engine · Jun 2026
“UNKNOWN -A catalytic converter clogged after being installed - only 14 months following installation, causing rough and unsafe acceleration, inability to shift gears properly, and need to drive with hazards on. It is clear that there is an issue with the engine/exhaust and system in this vehicle. Additionally, the car needs oil added regularly and seems to be burning it, as indicated by low level.”Owner report · Engine · May 2026
“Approximately one month ago I had a high pressure fuel pump installed in my 2018 Hyundai Tucson. While driving on the highway, about ten minutes from home, my car suddenly burst into flames. There were no warning lights in the cockpit. There was no smoke in the cabin. Another motorist flagged me down. I got out of the vehicle just in time for it to become fully engulfed in flame. It burned down on the highway. Police and fire responded. Insurance is investigating. If I was inside the vehicle, I would have certainly died.”Owner report · Unknown Or Other · Apr 2026
“The oil consumption issue has begun. At about 75k miles, my 2018 Hyundai Tucson 1.6L Turbo is burning oil at an insane rate. And there is no indicator of it occurring (no codes or anything on the dash) until it's too late. Hyundai is now WELL KNOWN, and aware, for this problem and it is a catastrophic safety issue because of the possibility of the engine seizing and disabling the vehicle. It isn't negligence on the consumers part either, especially when timely and consistent oil changes are being done. *NOTE* My vehicle has had the transmission (6 speed dual clutch) replaced at around 30k miles and is having the same issue again (at 75k miles). So first the transmission and now the engine!”Owner report · Engine · Mar 2026
“I bought this car 6 months ago. I did not know it had a recall on the engine. The engine just died a week ago. I brought it to hyundai and the confirmed it was a recall and go ahold of corporate. Corporate is refusing to fix the recall because they said "I should have brought it in at the original recall in 2020." I did not own the car there and I was not aware of the recall at all. [XXX] is my husband he is the other owner of the car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)”Owner report · Engine · Mar 2026
