2017 Hyundai Tucson: won't start

Filed Nov 4, 2026 · Engine, Fuel system · FL

While driving down the highway, the check engine light started to flash. Once the car was turned off and back on again, it shook violently. It was hard to keep it in the lane and I was worried it would cause an accident. It was driven off the highway while constantly shaking. Once it sat off for roughly 30 minutes, it would turn on, but wouldn't turn over and drive. It was towed to a dealership where it was diagnosed, though I was never given anything past a verbal "it stopped compressing". It turns on and over, but makes a grinding noise. It will die and turn off the engine after roughly 45 minutes. This had never happened before. *I've been told a few different things by people who hear about the problem, but I've never received a real diagnosis by the Hyundai dealership it is located at. It has always had a oil consumption problem, adding roughly one quart of oil every 800-1000 miles. It has had oil changes every 5,000 miles. It also had a hard time when cold-started accelerating, but would work fine once heated up. It is available for inspection upon request.

The engine (connecting rod bearings in the 2.0L Nu GDI engine) failed. The vehicle entered limp mode with DTC P1326, then died on the road and the engine seized completely (will not turn by hand when attempted; only clicks on starter). It is currently at First Hyundai dealer in [XXX], under Repair Order #XXXand available for inspection. The vehicle suddenly lost power and died while driving on the road. This created a significant risk of an accident or being stranded in traffic. I was on a busy highway and almost got hit twice. There is also a known fire risk associated with this exact defect (oil leaking onto hot engine components), as stated in Recall 209 (the federal safety agency 21V727). The vehicle was towed to First Hyundai. They have documented the no-start/seized condition on Repair Order #XXX. A prior independent scanner reading showed P1326 before the code was cleared. The dealer has not performed the full diagnostic inspection (scheduled around June 11). Hyundai Corporate (Claim #XXX) has been notified but has not responded after multiple escalation emails. The vehicle first went into limp mode ("Engine Protection Mode") with DTC P1326 on the scanner. Shortly after, the engine died completely and would not restart. This occurred after Recall 209 (bearing/KSDS campaign) was completed on XXX. Additional Details: This is a known issue with premature connecting rod bearing wear. The dealer is refusing to provide a loaner/rental upon drop-off, which contradicts TSB 22-01-023H (Dealer Best Practices for P1326 vehicles). The vehicle has been inoperable since 6/4 ..with no resolution. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle has a difficult time turning over when cranking, the RPMs are sticking and the car periodically shuts off at red lights. Several warning lights pop up when it won't crank and then other warnings when the car just completely shuts off at red lights. I drive the interstate in [XXX] daily for work, so with the engine stalling my safety is at risk every time I drive it. Likewise when it won't crank, my safety is at risk. I had two Hyundai recalls updated in my car in 2022, Hyundai Recall 209 which was a connecting rod bearing test and my car passed so they installed the other Hyundai Recall 966 which was software update for the knock sensor detection system to alert the driver of future issues. Those issues are now current. The software is detecting a critical failure which is why the car is shutting off - entering limp mode, or the engine is failing. On April 9th through the 11th, 2026 my vehicle was inspected by a Hyundai dealership, where a technician identified a developing engine concern and advised me to continue driving the vehicle.

Had had the vehicle approximately four months (purchased at Irwin Dealership in Laconia, NH) when the vehicle would not start. It was rendered non-functional. It was “repaired” in February 2023. When picked up in Feb after Irwin dealership in Laconia, NH had had it for almost 3 wks, they told me it had carbon buildup. It had only been driven about 4,000 miles since it had been purchased on [XXX], 2022. They changed the oil (oil changes are recommended every 5,000 miles). It died again on [XXX], 2023; again it had been driven less than 4,000 miles and was not yet due for an oil change. It has been there since. They (Irwin) wanted service records, I told them all I had from prior to purchase was the carfax, and that they had performed the only service because I hadn't driven it long enough to have even had a second oil change. When Irwin submitted documents to Hyundai, they indicated the issues with the car were due to neglect and poor maintenance. Hyundai refused to replace the engine citing that I had failed to provide service records. The car remains at the dealership, despite payments being made on a vehicle that can not be used.

After the engine was replaced we are still having electrical and engine issues and dealers in Atlanta area will not accept engine repairs. The car will not start consistently and most dangerous if we use our bights (lights) for just a second even, the car will shut down and restart when the bights are released. This was in stop and go traffic on the highway The radio will stop and do a reset while driving for no reason this has happened on multiple occasions but the bright on day reported below

Without warning, my car stalled and came to a stop while I was driving it. No warning lights had come on prior to the incident, but several came on after it stopped. I put the vehicle in park and attempted to restart it, and even though the start button lights indicated the the car was on, the engine would not start again. This is a safety issue because the car just stalled with no warning and I was not able to move it anywhere. If I had been on a highway or making a left turn, my children and I would have been seriously injured or killed. The car has been at the dealership since the incident, almost a week, and they have not yet looked at it or told me what is wrong with it. I have left 3 messages for the general manager and they have not responded.

I was driving my car and heard a rattling noise. The car suddenly started stalling and it cut off completely. Fortunately it cut off seconds before I entered the roundabout at a very busy intersection and i was able to roll into a shopping center parking lot. It wouldnt start again. Currently my car is at Bob Mayberry Hyundai. They ran diagnostics on or around Nov 9th. As far as I can understand I would possibly have to replace the engine. I was told they have to take a picture of the engine with the valve removed and send it to Hyundai and he said Hyundai also need all service records and they would able to obtain them. My car has around 65000 miles so its no longer covered under warranty.

As I was driving, the car began to slow down so I pulled over and the engine turned off. It wouldn't turn back on. Lights, radio, heat-all working but the engine doesn't start. We have it towed to the dealer and they say the engine seized up on us. It will be replaced because it is under warranty but it will take 1-2 months for a new one to come in. Apparently hyundai is aware of the issue and is redesigning the engines to fix the problem. How many times does this have to happen before they are recalled? What if you are on the highway and your car shuts off? No prior warning, nothing. They tried to give us the same bologna about engine maintenance and oil changes. This is a serious design flaw.
