limp mode check engine light code p1326

- Piedmont , SC, USA

My engine needs to be replaced. Out of nowhere it failed. No stuttering, no stalling, no check engine light or any other warnings. Just failed.

- Marlow , OK, USA

While driving under normal conditions, the engine began misfiring and losing power. Inspection revealed that two of the spark plugs had suffered a broken ceramic insulator, which likely occurred during a pre-ignition or detonation. As a result, the ceramic insulators were pushed through the engine causing at least one of the exhaust valves to burn leading to loss of compression resulting in engine failure on the highway. This engine has no current recall, despite numerous similar complaints. Hyundai has issued detonation-related recalls for other engines (like the Theta II), yet the 1.6L Turbo GDI engine in this Tucson is also experiencing similar failures. At the time of this complaint there are 955 complaints in the NTHSA database about this vehicle with more than half citing engine failure issues -?" many of them sudden and severe failures while driving. This creates both a safety risk and an excessive financial burden. These failures occur without warning and can leave the driver stranded. It is concerning that Hyundai has not acknowledged a defect pattern, despite consistent failure modes being reported across this engine type. I am requesting that NHTSA investigate the 1.6L Gamma II Turbo engine for potential systemic detonation or pre-ignition issues that can lead to severe engine damage. A recall or special service campaign should be considered, and Hyundai should be held accountable to cover these repairs.

The vehicle is experiencing severe engine shaking and misfiring during operation. Initial diagnostics confirmed that the spark plugs and ignition coils are functioning correctly and are not the source of the problem. A compression test revealed that two cylinders have no compression, indicating a likely internal engine failure. Potential causes include damaged or worn piston rings, valves, or a blown head gasket. This condition results in rough idling, reduced power, poor drivability, and potential long-term engine damage if not addressed promptly. Immediate engine repair or replacement is required.

I was returning home from a 224 mile trip. I was driving 65mph with the AC on low. Vehicle started slowing and losing power. I pulled over at the next possible location when I noticed the engine light was blinking then stayed solid yellow. I tried to rev the engine a few times only to be met with engine shutter and misfire. Had to have the vehicle towed the remaining 65 miles home. Took the vehicle to my mechanic where he stated cylinder 3 and 4 misfiring and told me this is a common problem with this vehicle. After doing my own investigations, I see this vehicle has an extensive history of the same problem from several other people. But yet no recall.... Why?

It is my belief that the engine is failing or has something wrong, due to an engine recall. I started having issues with acceleration and took it to a local mechanic who advised it was an engine issue and needed to be taken to the Hyundai dealer asap. As of today, May 27, 2025, it was taken to Autonation Hyundai in Columbia, SC who is alleging that all engine recalls related to my vehicle are not covering any engine issues. I have had this car for quite a while and have never had any issues until now. Multiple diagnostics have been performed.

There is an excessive engine oil consumption on the 1.6L turbo charged motor. Motor oil is completely depleted between recommended oil changes. It is a necessary to add roughly 1qt of oil per 1,000 miles driven, between oil changes, in order to maintain safe oil levels. No signs of leakage, therefore oil is burning at an unsafe rate.

In February of 2025, my oil lamp warning light came on. My husband checked the oil dipstick and noticed that it didn't have any oil on it. There was a visible burn mark as well. I called my local Hyundai dealer to schedule an appointment to see why my car was burning oil like that as it was not due for an oil change. The appointment was made for February 20, 2025. My car at that time had 79,803 miles on it. The Hyundai dealer suggested performing an engine combustion cleaning service, per Hyundai, to see if it would "fix" the problem. They also went ahead and did an oil change. After these services were done, I was told to bring the car back in after 1,000 miles. Hyundai's guidelines are that they allow 1 quart of oil loss per every 1,000 miles. I brought the car back to the Hyundai dealer after 1,000 miles and that was in April of 2025. I was told that my vehicle passed the inspection. The oil level on the dipstick was in the "normal range." After a few weeks, my husband checked the oil level again just to make sure the engine wasn't burning any additional oil since we were not convinced that the engine combustion cleaning service solved the problem. He checked it on May 11, 2025. The dipstick showed that it was below the L. I called the Hyundai dealer once again, and they were able to get me in on Tuesday, May 13th. My mileage was 81,792 on the day I brought it back in. They confirmed that it had burned over 2 quarts of oil in less than 2,000 miles. That is more oil consumption than Hyundai "allows" per their 1 quart of oil for every 1,000 miles rule. The dealer put in a request to Hyundai for a new engine replacement and I was denied due to my vehicle having no warranty.

1)Component that failed: Engine 2)Driving 75 miles on the interstate in traffic and suddenly losing speed was very dangerous. 3)Yes, the issue is still occurring, even worse now as my vehicle shakes just starting the engine. 4) The mechanic has inspected, diagnosed and attempted to repair. However due to the condition of the engine, and the cost of replacing it; fixing may not be an option. 5)The engine light began flashing and then went off; then back to steady on. I purchased this 2017 Hyundai Tucson used just 4 years ago. Everything seemed to be working just fine, I've had regular oil changes. On Saturday, May 10, 2025, as I was driving on the Interstate with my cruise control set, I began to lose power and my speed slowed. I took my car off of cruise control and pushed on the gas pedal to gain speed and my car started to shake and it struggled to pick up speed. My mechanic has changed the spark plugs and performed a BG upper engine induction cleaning; did compression testing and leak down testing. He found that cylinder 4 has no compression. In addition to that, he noticed there was oil on the spark plug. I had my oil changed 3 months ago, and less than 3,000 miles - my engine is burning up the oil to the point where the oil level is extremely low. I have now found out that this is a known issue with this type of vehicle. I'm told it's $10,000 to replace the engine. I have no warranty coverage since I'm not the original owner. I was not aware of the class action lawsuit that was settled last year. I'm extremely upset that Hyundai has not recalled ALL the engines for this make and model of vehicle as it seems EVERYONE has had engine problems.

Purchased this in June of 2024. Ran fine until August 19th 2024 when I was returning to work from my lunch break. I went home for lunch and everything was fine. On the way back, I was pulling out into highway speed traffic and while merging, the engine just stopped. No warning lights or anything. It just stopped running. The vehicles behind me luckily were able to see what happened and get around me without incident. Once I was able to coast back to a safe area, I proceeded to try to restart it with nothing but a click as a response. Tried a few more times with same result. Called roadside assistance and proceeded to check under hood. Found oil stick barely showing any oil when just under 2 months ago it was full, and I had not seen any warning light indicating low oil. Took oil cap off and felt what was inside and found metal shavings in oil. Roadside showed and pretty much confirmed the metal shavings and my worst fear. Still had it taken to a Hyundai dealership where they told me the motor was seized at it would be $13,200 to fix. Asked about the existing class action suit and pretty got told my engine wasn't part of it. After looking at all the complaints here, not seeing how they CANT classify this as a major issue. Still fighting with dealership I purchased from to get something done.

I was driving home from the store a short distance from my home. The check engine light came on, the car ran rough, lost power and would not accelerate. I was able to get home. My husband checked the oil; it was 2 quarts low. He previously changed the oil 3000 miles prior. He connected a code reader and it read "DCT 1326". I drove slowly on the berm of the road & able to get home. Had I been on an interstate, my life could have been endangered. Top speed a rough 30-40 mph. After my internet search it appears that oil consumption and engine loss is a common problem. My car has less than 60K miles. No prior history and oil changed every 5K miles.I am very upset about the lack of responsibility on Hyundai's part. This is our 3rd Hyundai and we were loyal customers.

- Manor, TX, USA

Engine experienced a catastrophic failure. Driving (normal commute) and clicking noise start coming from the engine. Got louder over a short time, but no dash waring lights came on. Further along the check engine light came, and when it started flashing I pulled over and called for roadside assistance (tow). No other warning lights came on. Engine temp read normal throughout. After the dealer service team reviewed, said the engine block was cracked and metal noted in the oil and filter. I contacted Hyundai USA to see if they would cover engine replacement. After a few days of review and back and forth with the dealer, they declined any claim. Dealer service rep quoted us approx $20k for engine replacement. We opted to sell to salvage company and now need to buy another car. Just over 66,000 miles and complete loss.
