NHTSA complaint #11523832

Owner complaint summary

I have been experiencing serious safety issues with the 2019 Hyundai Tucson I purchased that have been ongoing since February of 2023. The check engine light comes on, begins to flash, and the car goes into 'limp mode' and will not allow me to accelerate faster than 45/50 mph. Consequently, it will further stall on hills due to the inability to accelerate. Below is a brief timeline of this incident: - February 21: Bring in vehicle to dealer as recommended for oil change, tire rotation, cabin air filter, and a recall. The recall issue was as follows: 966 engine monitoring logic, 22-01-028H-1, caused by ecm update, 966 campaign, ecm update op code 10d021r9.3 - February: 24: Check engine light comes on, flashing, and unable to accelerate past 45-50 mph. - February 27: Return to dealer and bring in vehicle for check engine/no acceleration issue. - March 2: Pick up vehicle from dealer - March 8: Check engine light comes on again, flashing, and unable to accelerate past 45-50 mph. - March 9: Return to dealer and bring in vehicle for check engine/no acceleration issue. - April 5: Pick up vehicle from dealer - April 8: Check engine light comes on again, flashing, and unable to accelerate past 45-50 mph. - April 10: Return to dealer and bring in vehicle for check engine/no acceleration issue - April 25: Pick up vehicle from dealer - May 3: Check engine light comes on again, flashing, and unable to accelerate past 45-50 mph. - May 4: Return to dealer and bring in vehicle for check engine/no acceleration issue; car is still at dealer as of May 25
