The vehicle unexpectedly entered 'Limp Mode' due to engine tracking code P1326. The vehicle severely restricts engine power and RPMs while driving on public roads, preventing normal acceleration. This creates a severe safety hazard as the vehicle cannot safely merge into oncoming traffic, accelerate away from intersections, or maintain basic road speeds, putting me at a high risk of being rear-ended.The fault is under Hyundai Theta II Txxm. I have been given the runaround by both hyunday corporate and the local dealer.

This problem was observed about 1 month ago: While driving and headlights set on AUTO, during the day, and the light switch NOT on, the dashboard would indicate the lights were ON, for just a second or two, and would go off. At night with the headlights set on AUTO and the headlights ON, while driving, the headlights go OFF and ON briefly (1-3 seconds) causing a dangerous situation as visibility of road is lost. This condition was initially observed at night, after using the turn signals (left/right), but is now happening with greater frequency while driving without using turn signals. I Will schedule a visit with dealership to report/confirm problem.

Door latch issue. Driver's side door has to be pulled multiple times after unlocking to open from the exterior. Passenger side door latch has become completely inoperable and does not open from the interior or exterior now. To have multiple doors fail at the same time seems like a true design failure / flaw and an inoperable door a true safety hazard.

While stopped at a traffic light, the engine began producing a loud metallic clattering and clanking sound, consistent with connecting rod bearing failure (rod knock). There was no prior warning light or indication of this specific failure. When the light changed, the vehicle would not accelerate normally, leaving me stalled in a lane of moving traffic. I was forced to make an emergency turn to get the vehicle out of the way of oncoming and crossing traffic. The engine would not hold an idle afterward and has not run since. The vehicle was towed to a Hyundai dealership, where a service department employee stated by phone that this 1.6L turbocharged engine family has a known, documented history of severe factory defects affecting the connecting rod bearings.

All the warning lights in the day lit up. Brake, LDWS, AEB, outside air temperature won’t read and the a/c blows hot. $486 to diagnose at dealer and they state that it’s an electrical issue due to a bad vacuum pump. I can’t get an answer as to whether the vacuum pump safety campaign was completed or not. Dealer wants $1500 to replace.

The engine is failing at 128,000 miles. The car is burning so much oil that it is impossible to drive more than 500 miles without the oil running dry. The problem has been inspected by the Hyundai dealership nearest me. The vehicle notified me of the oil issue by illuminating the oil light. The issue started after the turbo failed at 127,000 miles. The turbo was replaced at a cost $3,500 and immediately afterwards the vehicle which previously did not burn oil now does. It doesn't just burn oil it consumes it like a black hole.

While driving, the vehicle experienced a sudden and severe loss of motive power accompanied by a loud, catastrophic internal knocking sound from the engine compartment. The vehicle was towed to an authorized Hyundai dealership (Piazza Hyundai of Limerick), where a certified diagnostic technician confirmed a severe internal connecting rod bearing failure (rod knock). This sudden engine failure creates a significant highway safety hazard due to the immediate loss of acceleration and power steering/brake assistance if the engine completely seizes while operational. Hyundai has issued widespread safety recalls and a 15-year/150,000-mile extended warranty (TXXM) for this exact failure mode in other engine displacements (such as the 2.0L Nu GDI), yet they have excluded the 1.6L Turbo engine from identical coverage despite it suffering from the exact same manufacturing defect and presenting the same public safety risk.

All the door locks and actuators/latches are failing. Hyundai claims there is no recall for it, and the price for one door repair is $1384... This is a safety issue since the passenger in the rear seat could not get out in an emergency!

Within the last month, the passenger side front door will no longer open from the outside even if the door is unlocked. The driver must lean over to open the passenger door from the inside. Then approximately one week ago, the passenger rear door began to have issues in that it would not open from the outside nor would it open from the inside. This is a known safety issue which puts passengers at risk. A Technical Service Bulletin 21-bd-006h extends the warranty coverage to 10 years/unlimited mileage, however my 2016 Hyundai Tuscon is six (6) months outside of this window. The local Hyundai dealership will not fix under this door latch warranty extension and quoted a cost of $885.00 to remove and replace both latches. I currently have a case opened with Hyundai USA Customer Affairs and am waiting to see if Hyundai will cover the cost of repairs and fix the two door latches. If they do not, I will consider legal remedies.

The vehicle severely shudders, jerks, and hesitates from a stop and while making a turn, during both acceleration and deceleration, making it entirely unsafe to drive. The vehicle has been completely un-driveable for the past 6 days. The check engine light illuminated, and on 4/9/26, the dealer documented a failed transmission judder test and kept the car, issuing a loaner. A temporary software patch failed after two weeks. Upon return, the dealer reported they were unable to recreate the problem, recommended returning when the vehicle demonstrates the problem more frequently, and refused to mechanically repair the dual-clutch transmission under my active original-owner 100,000-mile powertrain warranty, basically instructing me to continue to drive a seriously un-safe vehicle. Most recently, a yellow dashboard warning light illuminated, and the vehicle entered a dangerous 'limp mode,' severely restricting power and struggling to move before the light cleared after cooling down. The vehicle is completely un-driveable and parked.

Transmission previously replaced after failed Judder test. Transmission is failing again: Last few days the car will accelerate to 15 then it attempts to shift and power drops and pressing the pedal has no response or very little then it changes into what feels like 4th or 5th gear at 20 mph and acceleration is very sluggish and also switching into manual gear control is completely unresponsive. Power drop at 15 mph, the transmission jumping into what feels like 4th or 5th gear at 20 mph, and sluggish acceleration — is consistent with the clutch pack slipping and the TCM essentially giving up on lower gears and defaulting to a higher gear to protect itself. Manual mode being completely unresponsive is a significant red flag — it means the TCM may have entered a limp or failsafe mode where it’s overriding driver input entirely.
