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 …

2022 Hyundai Elantra Hybrid Limited with 25000 was fine when I drove home from work. An hour or two later, got in vehicle which then shuddered and died. Manufacturer deflected blame to avoid performing repair under warranty but needed a new alternator. Car went into limp mode and just would not start once engine cylinders misfired (all cylinders misfired!). This issue after they refused to repair or tow, deemed it safe but almost wrecked due to it dying when driving off the lot assured there was no issue.
