2017 Hyundai Tucson: stuck in gear or won't shift

Filed Oct 7, 2026 · Acceleration, Electrical · VA

While going down the highway at around 72 mph , my car went into limp mode. I was unable to accelerate, the brake and wheel locked. And then the engine light began flashing. The limp mode , non acceleration, and flashing engine light have happened twice before this instance. The first two times the pulled the P1326 knock sensor code and replaced it. Did the update, and sent me on my way saying it was fine. Now this most recent time (the 3rd time), the engine has failed. A CARFAX report says my car already had the engine replaced at 52k miles, meaning there’s 1 something internally wrong and 2 it’s still well within mileage warranty for another engine replacement. This car is extremely dangerous as it can literally stop in the middle of the highway. I went from 72 to about 15 mph in seconds, I was unable to get over or accelerate. It was terrifying. Now dealing with Hyundai - they don’t want to take fault.

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.

Following the knock sensor detection system update, this car has a P1326 code that forces it into limp mode. Occurs during moderate-hard acceleration, e.g. getting on a highway. The car is limited to ≤2000 RPM and ≤ 45 mph, and rapidly decelerates to that speed if necessary. Acceleration is very limited. This occurs roughly every two weeks, despite having a brand new sensor installed by Hyundai. Hyundai has also allegedly performed cleaning on the sensor and related parts. This has been going on since November, when the recall that installed this update was performed.

am submitting a safety complaint regarding my Hyundai vehicle due to repeated engine power loss (limp mode), excessive oil loss, and a denied engine recall replacement. I initially brought my vehicle to the dealership after experiencing engine power loss/limp mode, engine oil loss, and illuminated check engine warning lights. The dealership confirmed that my vehicle was covered under an engine recall and stated that the recall procedure was completed. As part of this process, the dealership performed an engine combustion-related service and charged me approximately $1,600. After this repair, I drove the vehicle for approximately 1,000 miles. When I returned the vehicle to the dealership, the vehicle entered limp mode on the same day it was brought in, and the check engine light was illuminated again. The dealership advised me that the vehicle had lost an excessive amount of engine oil during the 1,000-mile period. Due to the continued engine issues and oil loss, the dealership requested a full engine replacement under the recall. However, Hyundai denied the engine recall replacement request. The vehicle’s repeated loss of power, excessive oil consumption, and limp mode create a serious safety concern, especially while driving at normal road speeds. I am concerned that the recall remedy was ineffective and that the denial of an engine replacement places drivers at risk. I am requesting that the federal safety agency review this matter for potential safety defects and improper handling of a known engine recall issue.

Oil consumption problem caused vehicle to go into Limp Mode on freeway. Manufacturer states 1qt loss every 1000 miles is acceptable.

My 2017 Hyundai Tucson has completely broken down will not go into reverse had a diagnostics at Hyundai. I thought it was going to be covered because of the class action suit. My car apparently was not in the recall or the suit. I don’t understand I have the identical problem of the dual clutch transmission issue. I’ve tried to get Hyundai to do good-faith repair they refused. I’ve contacted Carmax where I purchased the vehicle. They had the car when the lawsuit was finalized I didn’t know anything about the lawsuit or the problem with the vehicle. I’ve had the car for five years it’s at 85,000 miles. I don’t know what to do.

The engine is failing. Our vehicle continues to experience tremendous oil consumption and it's all of a sudden gone into "limp mode" where we lose engine power even after the knock sensor recall update was performed. No check engine lights, no indication of what's happening and it just loses power on the highway as well as city streets. It's a danger to everyone around us and it's a danger for us as we try to drive the vehicle. The dealer / Hyundai had us do 2 oil consumption tests but would not do anything to fix the issue. They informed us they needed to replace the engine after the first oil consumption but then they backed off of that and didn't fix the issue. It’s just gotten worse. We also had a transmission service done and they said the transmission looked fine. We took it in for a diagnostic just after this as the power issue began in "limp mode" where we lose engine power. They are trying to say it needs a new transmission but with the known issues with the Hyundai oil consumption and engine issues where the vehicles go into power loss / limp mode, we’re reporting this issue for our safety and the safety of the community as it’s unsafe to drive this care. We hope you will push Hyundai to do a recall for the engine not just for us but for all Hyundai Owners who are dealing with the same issue.
