Hyundai Tucson fuel smell problems

Filed Sep 28, 2026 · Fuel system · TX

An authorized Hyundai dealership performed a major engine replacement on my vehicle on June 11, 2024. The vehicle mileage was documented as 110,797 miles in and 111,799 miles out. In September 2026, after the vehicle had reached 129,430 miles, I brought it to an authorized Hyundai dealership because of a severe gasoline odor and evidence of gasoline entering the engine oil. The dealership documented the vehicle at 129,430 miles in and 129,431 miles out. The documented mileage from the 2024 engine replacement's out-mileage of 111,799 to the September 2026 diagnostic in-mileage of 129,430 is 18,633 miles. The vehicle was returned to me, but the fuel/oil contamination condition recurred within approximately 48 hours. The oil level subsequently increased substantially. I repeatedly requested the dealership's technician narrative, diagnostic findings, test results, and electronic service documentation showing what was inspected, what was tested, and what findings supported the dealership's diagnosis. The dealership performed the work, yet these records have not been provided to me. Hyundai corporate has also not provided the requested documentation and has directed me toward additional diagnostic expense rather than providing the records from the inspection already performed. The 2024 engine-replacement documentation lists the replacement engine and associated service parts, including service kits 21111-2GK50-QQH and 21111-2GK70-QQH, as well as oil-cooler pipe/hose assembly 25470-2G050-QQH. I am requesting that the actual service records establish what components were installed, replaced, transferred, or reused during that repair. I am not claiming that the available information by itself establishes the root cause. My concern is the recurrence of apparent fuel contamination of the engine oil only 18,633 miles after the documented engine-replacement out-mileage, combined with the lack of diagnostic documentation from the authorized dealership's inspection. I am su

This vehicle has a considerate amount of oil dilution problems. I have had this vehicle taken in for service several times due to gasoline mixed into the engine oil. Again on March 6 2026 for the 4th time now the vehicle has a check engine light extreme hesitation with an almost stopping jerking motion due to dilution problems. Multiple dealerships claim there is nothing wrong with the car.. there is a distinct gasoline smell in the engine oil. The vehicle at times is almost unsafe to drive due to the hesitation and halting it does on its own. Every time a dealership is contacted my problem is dismissed. There is a burning smell due to the oil gas dilution issue. The car reaches higher temperatures than it should. And now the Hyundai dealership is making me wait almost a month again to have the problem looked at again which then puts me as the driver in an unsafe situation to drive a vehicle with such hesitation and fire risk. If they dismiss this oil and gas mix again and do not repair the car it could seize my engine or maybe possibly even cause fire damage.

My vehicle began experiencing issues around 83,000 miles. The engine started burning oil, showed shuddering during acceleration, and there was a noticeable smell of gasoline inside the cabin. Eventually, the car wouldn’t start, so I had it towed to the dealership. The technicians confirmed it was running rough and behaving abnormally. The Hyundai dealership conducted a full inspection and diagnosed several issues. They replaced the spark plugs, performed a GDI-safe induction cleaning, replaced the coolant and brake fluids, completed a transmission fluid service, installed a new battery, carried out wheel alignments, and changed the cabin air filter. All of this work was completed in October 2024. However, in December 2024, I had to return to the dealership because the fuel smell inside the cabin persisted. Although they couldn’t find the source of the issue, the smell eventually disappeared after the visit. Following that, I was advised to check my oil every 3,000 miles due to the GDI engine's reputation for burning oil quickly. Despite this, the car began running rough again, and when I checked the oil, it was completely dry—well before reaching the 3,000-mile mark. I had to get another oil change sooner than expected. Unfortunately, the issue continued. I brought the vehicle back to the dealership for another inspection. They suggested starting a monitoring process where I would bring the car in every 1,000 miles to check the oil levels. After driving 1,000 miles, the oil level was just slightly above the low mark—still not normal for such a short distance. I urgently need assistance to move forward with the engine replacement process before my warranty expires. I am currently at 91,000 miles.

Engine sputtering before turning on and strong gas smell throughout vehicle and near engine

Within the first year of purchase, my power train system has beeb throwing codes. I took it to the dealership where they assured me nothing was wrong. My fuel injectors then gave out. The dealership replaced them and told me “yes these things are faulty and we see it a lot”. After replacing it, they did not seal the fuel injectors, causing gas to gush out and set my car to smoke. I was ill from inhaling gas fumes for days. They took accountability and said that the injectors were defective in the vehicles and that they would once again fix it. I am not experiencing further engine issues which they do not know how to diagnose. My car is a 2022 purchase from the lot. The engine is defective and Hyundai is negligent. They admitted they were aware of the injector issue but didn’t do much to correct this. After corrected, they almost had my car set on fire from fuel pouring on the engine.

(1) [XXX] (14,568 mi): The vehicle had been running normally. My wife was about to switch lanes at an intersection when the vehicle started to shake and vibrate. The entire dashboard lit up and the vehicle quickly died. She tried restarting it and the engine wouldn’t turn over. Anytime there was an attempt to restart, there was a potent odor of gasoline. The car died in the middle of the road. It would sort of start but then it wouldn't move and would just shake and smell of gas. After many minutes of trying to start the vehicle, barely got power but was able to pull to side of road around other cars. Hyundai app reported codes: P030300 and P217800. Had car towed to local dealer. Picked the car up and next day spoke to the service manager who indicated there was a 20%-25% chance this would reoccur. He said there was nothing he could do as Hyundai would only cover the cost for the existing issue. The paperwork from the dealer shows it was a P0303 for cylinder 3 misfire and system too rich caused by leaking fuel injector for cylinder 3 (low pressure). [XXX] (14,702 mi) I was driving the car, in middle of an intersection and the vehicle started to vibrate and all lights on dash lit up (check engine, battery, etc.) and smell of gasoline. Car hesitated and wouldn't move. Died in intersection. Had to have 2 people help push me as I was dead in middle of road with people beeping and passing me. Got to side of road and couldn't get vehicle to start. No error codes on app this time, but all symptoms were exactly the same. Called for tow, different dealership due to location. Dealership indicated they would return it to us safe, but because of Hyundai policies, they can only work on the affected items. This is well documented by Hyundai owners of this problem and going by what the service manager of the first location told me, this is common to spread to other injectors. THIS IS UNSAFE! TWICE IN MIDDLE OF INTERSECTIONS! TWO MORE INJECTORS! SOMEONE IS GOING TO GET HURT! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFO

I had my top engine block (not sure why not a full engine replacement) replaced under warranty June 2023. Shortly after the fix my AC unit stopped working. Once I got my AC unit fixed, about 1.5 months after my engine was not performing. My car would not turn over and when it did, it was in limp mode and would not run properly. I had it towed to dealership who could not find the issue until after they took out of the bay and went to move it, it wouldn't start. They replaced the crankshaft positioning sensor and it wasn't covered under the extended warranty. The top engine block only has 10k warranty which is fast approaching. Took car home and when accelerated past 60 car shakes and when i brake car shakes. Now car cabin smells of gas. All cars with KM are having multiple issues. Dealership not calling back regarding gas issue and has not responded to if they touched my tires. Local Mechanic said all my wheels were unbalanced.
