Owner report 11457937 · 2022-03-23 (March 23, 2022)

On multiple drives the car has "lurched" or accelerated when foot was NOT on the accelerator pedal. These were minor issues, but unnerving when pulling up to park near a structure. Today 3-23-22 I was driving and after about 1 hour of normal operation the car began to accelerate while pressing the brake, and decelerate while pushing the gas. The engine was revving and then slowing down opposite of what would be expected. This is a hybrid vehicle - it felt as if the gas engine was supposed to be spooling up to charge the battery but instead …

The first time it was taken to the dealership and “fixed” - now it has failed again. The second issue is that the car accelerates on its own, both at a high and low rate of speed. While traveling at approximately 60 mph on multiple occasions, when the engine transitions from the electric motor to the gas engine, it will suddenly rapidly accelerate without any additional pressure on the gas pedal. While braking at a low rate of speed, the car seems to fight the brakes and will accelerate instead, propelling the car forward… Look up ODI 11530328 at NHTSA ↗	1730.9% ODI 11526901 I was rear ended and the air bags didn't deploy.

This has happened multiple times and the dealer claims they have never heard of this happening. It could cause a serious accident when it happens.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.

The component has not been inspected by any other sources outside of the Hyundai certified mechanics at the dealership. No warning lights or messages appeared at time of occurrence; however the engine would rev up when switching between hybrid …

When the feature activated, I felt the car jerk a bit to slow down, and sort of swerve in one direction before righting itself. There is a possibility that the feature activated because I had manually enabled the Auto Hold fe…
