2016 HYUNDAI TUCSON Complaints

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.

The contact owns a 2016 Hyundai Tucson. The contact stated while driving 50 MPH, the vehicle failed to accelerate as intended and stalled. There was no warning light illuminated. The contact was able to pull over to the side of the road, where the contact restarted the vehicle. The contact drove to his workplace and parted the vehicle. However, the vehicle later failed to start. The vehicle was towed to the dealer it was purchased from, and the contact was informed that the engine had failed. The vehicle was not repaired. The vehicle was then towed to Affordable Towing and Repair, where it was diagnosed that the engine had failed and needed to be replaced. The manufacturer was not contacted. The vehicle was towed to 125,000.

Driver door does not open from the outside. Rear passenger door does not open at all.

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.

The power window motor and regulator on the drivers side failed to roll up the window. It was raining and made it stessful driving home . The window was stuck down and the rain was soaking the inside of the car. Very distracting while driving.

Oil drains very fast even with regular oil changes and maintenance. The vehicle began shaking and then completely stopped with very little warning. Check engine light flashed for under 60 seconds then vehicle would not move forward on the highway creating a major safety hazard. Engine smelled hot and like burning rubber.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the check engine warning light was illuminated and there was an abnormal sound coming from the engine compartment. The vehicle was taken to a dealer where it was diagnosed that the vehicle needed an oil consumption cleaning. The vehicle was repaired however, the failure persisted. The manufacturer was not notified of the failure. The failure mileage was unknown.

The engine in this 2016 Hyundai Tucson has experienced progressive failure symptoms consistent with the known rod bearing defect covered under Hyundai's engine warranty extension campaign. Symptoms include: excessive oil consumption requiring frequent top-offs over several months, severely degraded acceleration, failure to upshift under load, and an audible metallic crunching noise occurring around 4,000 RPM. A knock sensor fault code (P1326) was previously triggered (on 2/16/26), confirmed by a mechanic (on 2/17/26), and cleared. The dealer was visited (on 2/17/26) and refused to perform the campaign repair, stating no active code was present at that time. The vehicle is available for inspection. The problem has not been confirmed by the dealer despite a visit; the dealer declined to act citing absence of an active code. The vehicle has not been inspected by police or insurance. Warning symptoms include the prior knock sensor code, oil consumption, loss of power, and the current mechanical noise. Symptoms first appeared several months ago and have progressively worsened. The dealer's refusal to act under the existing campaign despite documented symptoms has left this vehicle in a dangerous condition on public roads.

Both rear doors actuators will not allow to open from inside or outside, the passenger will open from inside and the driver door intermittently is the same and I have to juggle the handle or smack above the handle to get it to open on driver side. The passenger is only opening from inside and have to smack above the handle or put pressure to door to have the actuator release....both rear doors do not open at all. This is a safety egress issue. I have minor children and they cannot get out of the vehicle and if an emergency, the first responders cannot get into it.

Took vehicle to dealership and had it diagnosed for the electrical system faults cause all the dashboard warning lights came on. Shop said it could be bad vacuum pump.
