2015 Hyundai Tucson Transmission Problems

Shortly after you took delivery of your used 2015 Hyundai Tucson, the engine suddenly lost power while you were driving, leaving you stranded on the roadside. Multiple warning lights appeared on your dashboard at the time of the failure, and the vehicle would not run afterward. The exact cause hasn't been identified yet, but it appears related to the engine, fuel system, or electrical components. Diagnosing the root cause and repairing or replacing the failed component will be necessary to restore the vehicle to working condition.

While driving on the highway, your engine suddenly shut off without any warning light, and your car lost all power with a truck directly behind you. You saw two puffs of smoke from the tailpipe, but heard no engine knock or ping sounds before it happened. The engine would not restart, and after a battery replacement didn't fix it, two repair shops diagnosed a seized engine.

While driving at 70 mph, your 2015 Hyundai Tucson lost all engine power without warning, forcing your husband to swerve across lanes and pull onto the shoulder. The engine light came on after restart, and a mechanic confirmed the engine was completely seized. Hyundai claimed the engine wasn't covered under warranty because a service campaign (related to the KDSD system) was never completed on your vehicle, even though you were never notified of it and it was only a software update that warns of problems rather than fixing the underlying engine defect. The engine required complete replacement but was denied coverage.

Your engine is burning through 3-4 quarts of oil between oil changes, which causes the car to enter limp mode (reduced power mode) until you add oil and restart. Your transmission is also slow to shift from 3rd to 4th gear, sometimes not shifting until you reach 65 mph. When limp mode activates, you lose power on hills, which has created dangerous situations. No warning lights appear on the dashboard until the problem occurs.

Part 43777-1G100 Pin-Snap is Part Code 43777B does not keep linkage attached to transmission shifter, it broke/snapped off due to wear and tear on a vehicle that only has 65,000 miles on it causing the vehicle to be stuck in drive.

I am writing to express my concerns regarding the recall repair performed on my 2015 Hyundai Tucson on October 5th, 2022. I have received numerous letters from Hyundai regarding an open recall and finally received a notice stating the remedy was ready. I scheduled an appointment with Matthews Hyundai of Syracuse and took the vehicle for the recall. Unfortunately, after taking the vehicle back to the dealership, I was advised that the check engine light was on and the issue was a result of a faulty knock sensor and purge valve. I was asked to pay more than $100 for the repairs. However, after further discussion, it was concluded that I wouldn't be charged. However, after only two days, the engine check light came on again, and the speed reduced to 45 MPH on the highway. I was then told that the problem was from the ignition coil and was charged $232.72 for the repairs. Despite paying the full price, the same problem occurred again, and I had to take the vehicle back to the dealership seven times, paying a total of $1,160.67. Throughout this recall repair failure, the vehicle's check engine light would come on, or it would randomly lose power, making a knocking sound and reducing speed even while driving. I no longer feel safe in this vehicle, and it has resulted in thousands of lost wages as it is the only vehicle I use for my work and personal use. On December 1st, I wrote a complaint to the New York division of vehicle safety and was advised to take the vehicle to a different Hyundai authorized dealership for diagnostics. I took the vehicle to Burdick Hyundai of Cicero, and after a week, they stated they were able to find the problem. However, Hyundai denied the claim for repairs on the vehicle. Since then the vehicle inspection has expired, and I took the vehicle to a shop for inspection. They stated they could not pass the inspection as the vehicle speed would not exceed 45MPH.

Previous History: Vehicle already required an engine replacement - short block assembly. Current Details: DTC P01326 - While driving - Check Engine Light blinks & vehicle's acceleration is immediately reduced, causing dangerous disruption to the flow of traffic while merging into traffic from exit ramps, at traffic lights, stop signs, turns etc. Has been to dealer 3x for diagnosis and repair. Jan 2022 - 1st attempt - Knock Sensor replaced (Recall 966 was performed in Nov 2021) 2nd attempt - Knock Sensor software updated - 3rd attempt - Knock Sensor disconnected and reconnected. After each repair attempt the vehicle continued to suffer reduced acceleration and blinking check engine light while driving within a day or two. 4th time - DTC P0087 - Fuel Rail/System Pressure - Too Low & DTC P2191 System too Lean at Higher Load (Multiple) (Bank 1). These are "new" codes discovered by subsequent Hyundai dealership after the 3rd repair attempt unresolved by the original selling dealership. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others. The warning check engine lights did appear at the same time as the reduced acceleration and occurred each time spontaneously while driving. The vehicle is available for inspection upon request. There are additional complaints involving 2015 Hyundai Tucsons listed on the NHTSA website which I do not see connected to a current or previous recall. However, I do see Hyundai issued a recall # 207 in 09/2021. Please note the similarities of referenced complaints show the first 8 characters KM8JT3AF of the VIN show a direct correlation to manufacturer and engine types. Also note, there is an open unresolved recall # 218 with the potential to cause fires and currently has NO REMEDY available. Recommendations from Hyundai are to park vehicle away from buildings and continue driving even with fire hazard?

I was driving and there was a knocking noise from the engine and loss of power. I opened the hood and noticed a pulley on the belt that looked loose and had the car towed to the dealership. According to them they know this particular engine Theta model has been an issue for fires and engine failure with components breaking internally but no recalls have been addressed for my VIN number even though there are hundreds of thousands of customers with the same issues and only some recalls have been made. Ultimately leaving the customer with the bill. This is a very dangerous situation and reading hundreds of comments on various sites and these incidents happening in other countries as well with this engine, there should be a huge investigation and something being done about this.
