The contact owns a 2016 Hyundai Tucson. The contact stated that while driving at 15 MPH, the vehicle failed to accelerate when the accelerator pedal was pressed and released repeatedly at 1,200 RPM. The transmission warning light illuminated. Additionally, the rear driver's and rear passenger's side doors failed to open. The dealer was notified of the failure but informed the contact that there was no recall associated with the VIN. The contact associated the failure with the federal safety agency Campaign Number: 16V628000 (Power Train, Electrical System); however, the VIN was not included in the recall. The manufacturer was notified of the failure by email. The failure mileage was approximately 95,000.

Component: Power Train / Automatic Transmission / ActuatorsDescription: My 2016 Hyundai Tucson (1.6L Turbo 7-speed DCT) suffered a catastrophic transmission assembly failure that caused a sudden and dangerous loss of forward motive power while driving. The vehicle completely refused to engage forward gears, creating an immediate traffic hazard.A certified Hyundai dealership diagnosed the vehicle and pulled fault codes P073F73, P073F77 (Unable to Engage Gear 1), and P092177 (Gear Shift Forward Actuator Circuit Performance). These codes explicitly confirm a total mechanical and electrical failure of the transmission shift actuators.This failure mirrors the exact safety risks and clutch-slippage/engagement defects outlined in federal Safety Recall Campaign 149 (the federal safety agency Campaign Number 16V574000). Hyundai Corporate refused to provide any goodwill coverage, citing that the vehicle is out of its standard warranty period. However, the failure of these actuators is a direct consequence of the known, recurring manufacturing defect that prompted the initial federal safety recall. The vehicle remains an unresolved 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.

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.

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.

Hyundai Tucson Sport 2016 GDI engine. I am the original owner of this truck I have taken care of this truck so much it being my first brand new purchase. No oil leaks NOTHING! When I first purchased the vehicle I noticed that it would stall when I would accelerate but did not think too much of it since it was brand new. A few years passed started to notice frequent oil changes were supposed to be made. Another few years turbocharger went out had to get it replaced. The engine consumes so much oil at first I thought it was because the turbocharger was out so when I got it fixed I thought that would fix that issue and it didn’t. I got an oil change March 2, 2026 and on March 21, 2026 I was on the highway and the truck started to shake really bad I exited the highway went straight to the oil place they said I had no oil on the dipstick I got ANOTHER oil change (expensive) and when I turned on the car to leave the car shook again and the engine light was flickering on and off and finally stayed on the dash board. Barely made it home. Got a tow truck to tow it to Hyundai dealership they told me they will not see it unless I pay the diagnostic fee of $200 and even then they think it’s the engine with everything I described to them. They said since there are no recalls on the Tucson that Hyundai will not do anything for me I would have to pay out of pocket for everything. Had to pay the tow truck again to tow it to my house ($250). My car has all the symptoms all the other cars have that they have recalled. This is a huge safety issue because i drive on the highway a lot and everyone knows a car with no oil is extremely dangerous.

The transmission began slipping and hesitating within days of purchase. The vehicle intermittently fails to accelerate when pressing the gas pedal, especially when pulling into traffic or crossing intersections. This creates a serious safety risk because the vehicle does not respond when needed, leaving me exposed to oncoming traffic. The issue is intermittent and does not always trigger warning lamps or fault codes. The problem has been reproduced multiple times by me while driving under normal conditions. The selling dealer performed only a brief test drive and stated they could not duplicate the issue, but the hesitation and failure‑to‑accelerate continue to occur. The vehicle has not yet been inspected by Hyundai, but the symptoms match known issues with the 2016 Tucson’s dual‑clutch transmission and TCM logic. There were no warning lights prior to the failure, and the symptoms first appeared within the first week of ownership. The vehicle is available for inspection upon request.
