2015 Hyundai Tucson: stuck in gear or won't shift

Filed Apr 5, 2025 · Engine, Transmission · PA

The engine uses about 3 to 4 quarts of oil before a oil change the it will go in limp mode. I have to get it rest and then add oil for the engine to run right. Also transmission don't want to shift 3 to 4 gear it will be 35 mph to 65 before it shifts. When the car goes in limp mode I lose power going up a hill and almost got rear ended. They won't do anything do to its a used car. No lights came on the dash till it acts up.

Our 2015 Hyundai Tucson check engine light started flashing and went into "limp mode" while driving on the freeway. Limp mode means the car loses power to accelerate, struggles going up hills, and limits speed. Thankfully I was not pulling out. The vehicle was towed that day to a mechanic who found traces of metal in the oil (see documentation). The vehicle was then towed to the Hyundai dealer. The dealer explained there is a common problem with Hyundai engines failing due to rod bearing issues and PistonSlap. I later learned the dealership covers the rod bearing issues due to a court settlement from being sued for so many engine issues. The dealership said if they found it was an engine bearing rod issue (ring connecting to the piston) they would replace the engine since it was a safety issue. They claimed if it was a piston slap it would not be covered (even though the bearing rod is connected to the piston and could potentially cause PistonSlap). After checking that the car had been taken care of extremely well with oil changes around every 3 months and all safety procedures had been taken they performed a bearing clearance test. The test passed without error detection so they changed the existing knock sensor. We were directed to drive the car and if the sensor turned on again to bring the 2015 Tucson back. We did and a week later, the new Knock Sensor reported there was something wrong with the engine again. I also noticed when checking the oil that smoke came from the dipstick tube. We took the car to the Hyundai dealer again. They did the bearing clearance test again. It passed again but this time they detected a rattling noise coming from the engine block. According to the records the noise was loudest to cylinder 4. The dealer claimed we needed a new engine that would cost about $9,500. Clearly, this is a piston-manufactured defect. With metal floating in the oil and a limited piston warranty it encourages the owner to drive the car until it brakes.

I have a 15 Hyundai Tucson that has been shutting off on me while driving on a highway going between 55 mph to 70 mph. Engine went into limp mode, CEL is on and flashing. Knocking noise heard from engine and consuming oil. Diagnosed with P1326 code. Brought to local Hyundai dealership. Even though road test stated normal operation, technician notes that vehicle DID stall, shut off, on return to the shop. No codes. Was told Hyundai would not pay for man hours to look into further. So allowed me to drive off their lot. Upon re-search I found, with NO help from local Hyundai or the dealership I purchased vehicle from, that my VIN number is associated with the E2 class action settlement that just went live May 2023, that my engine is indeed infected, like a cough before the cold, and has the potential of starting on fire/failure. Now I purchase this vehicle in 08/2023 with no disclosure of this very concerning problem. I am told by Hyundai USA that there is a paper trail that every affected VIN in the settlement has been notified, by law, to owners of affected VIN’s, and still not disclosed. I reached out to Hyundai USA at the national level, was given a case manager, who sent my case to the buyback/legal department. My case manager reached out and stated that my case has been denied due to age and mileage of vehicle (even though automatically extended to 15yr/150,000 miles) I asked what my next steps should be as my vehicle is still shutting off on me while driving and was told to have a different Hyundai dealership diagnose vehicle, but to not tell them all of the information of it already going to one Hyundai dealership. I was told if I hear a noise from the engine that I should pull off to the side of the road and call for a tow truck. I said so Hyundai USA feels good allowing this vehicle to be operated on highways knowing the symptoms I am experiencing. They obviously do not care for my safety let alone passenger safety, nor other motorist on roads.

Bought vehicle from dealership and 20 days later my car shut off as I was driving. Spoke to dealer they had me bring to her mechanic that she use since it was going to be in the shop dealer agreed to put new pads and rotors on. Picked up vehicle, ask them about the problem. They told me that it was all good and that they just cleaned up the mass air sensor that was dirty. Brought vehicle home. Mid of Oct driving down highway/55 mph vehicle shut off again on me this time it went into limp mode. Call dealership back and she wanted me to drive it to shop. I stated I’d did not feel comfortable driving it 45 miles in limp mode. Local shop Looked at it discussed with dealership. I finally spoke to the shop they gave me the information of the codes. Dealership texted me not phone call told me all about the code It was pulling and recommended that I take it to a Hyundai dealership as there is a service campaign on the vehicle. Dealership sent bank a copy of the service campaign. It states as required by federal law dealers must not place vehicle into customers use until campaign and all open recalls performed on vehicle. Campaign states it is a safety action. Campaign also states Q&A on the campaign. Hyundai strongly encourages customers to get this fixed. Also states what will happen if the wear in the engine bearings are malfunctioning. Also states that dealers will inspect and if necessary replace the engine. this is the second time vehicle has shut off while I was driving on Wisconsin highways. I have informed dealership that it was the second time that it has done this and that it was unsafe. Then I find out that the first shop I took it to that works with the dealership put in a used transmission a new Cadillac converter days before my purchase, and neither in person prior to signing purchase agreement nor on the Wisconsin buyers guide does it show that this dealership replaced anything into this car. I have only driven 1400 miles. I spoke with dealer, she won’t help!

While driving the vehicle suddenly went into a limp mode and had a flashing check engine light. The vehicle was in limp mode for approximately a half mile prior to having complete engine failure and shutting off completely. Vehicle has always been properly maintained. Dealer confirmed engine is seized. A manufacturing defect with the Theta II engine caused the premature engine failure. If this occurred on a major highway myself and other motorists would be put at a significant risk as there was limited time to act and find a safe place to roll to a stop.

Knock sensor repeatedly puts the car in limp mode. Loss of acceleration is dangerous. Dealer resets sensor and claims can't find anything wrong. This issue is widely reported.

I bought this car as a lease return at 36k miles. I have taken it in for all the recommended services and also the oil changes at the recommended intervals. Never had an issue with the vehicle at all till now. At just over 70k miles I was driving at 75mph and the engine lurched and the vehicle went into limp mode. The fastest I could go was 60mph. The engine had a wicked knocking sound. Fortunately I was near a hyundai dealership so I took it there. They said it needs a new engine. Thankfully I have the certified pre-owned warranty on the engine & powertrain up to 100k, so hyundai is eating the cost. But it is still wildly concerning to me! I'll for sure be selling this car before it hits the 100k warranty.
