Since December 18, 2024 I have had this happen 5 times. I come to a complete stop and have my foot on the brake. The car will then hop four-five times (like the sensation of shifting in manual with a cluch and you don-??t shift correctly and the car will hop). I am not sure why this is happening. I took it to the dealer and they haven-??t experienced the issue. This doesn-??t happen at every full stop either.

I have had 2 intermittent issues since I bought this vehicle brand new. 1) Hard, Jerky shifting from 1-2 or 2-3 gear 2) Huge safety issue regarding loss of power and inability to accelerate from a stop even though the car is on and in drive. This has happened to me multiple times and is very intermittent so it is hard to replicate. This has happened when I am attempted to accelerate from a complete stop and the car begins to move but then does not accelerate at all. Almost as if the powertrain shut off even though it was moving under its own power a fraction of a second ago. This has happened to me multiple times with my entire family in the car as we attempted to enter intersections leaving the car powerless with oncoming traffic. Thankfully we were not hit by another car but could have been.

Several times per week, when I go to accelerate after being at a complete stop, my vehicle hesitates and does not pick up power. It very slowly accelerates and feels as if it-??s going to stall, then suddenly revs up and accelerates, but revs up higher than it should before finally getting to the appropriate speed/rpm. This is very unsafe as I cannot pull out into traffic, even if I should have time, because I don-??t know if it is going to accelerate or not. One of these days I am going to get T-boned! I took it to the dealership and they did a software update that was supposed to fix the issue, but it did not. The issue still happens several times per week. There are no warning lights on the dash. The dealership did not run a diagnostic because they told me I would have to pay for it if no codes came up. I-??m not willing to do that, as I feel since the vehicle is under warranty and having issues, the diagnostic should not be my responsibility to pay for. I cannot say a specific date when it occurred (below) because it occurs often.

On high-temperature days, when the A/C is running at full capacity, the vehicle occasionally fails to accelerate from a stop. This issue persists even after applying the recommended ECM update. The lack of reliable acceleration poses a significant safety risk, particularly when turning across oncoming traffic or entering a busy street. This situation can leave the vehicle stalled in the path of approaching vehicles, increasing the likelihood of an accident.

Sometimes the vehicle will be very sluggish when accelerating from a stop, it is hard to replicate, and inconsistent.

- Georgetown, TX, USA

When accelerating from a stop, there is a hesitation or lack of power when stepping on the accelerator. Releasing the accelerator and depressing it again will get the car going. The engine also revs high at low speeds before dropping to the next gear.

when moving from a full stop, the car sometimes has hesitation to move to a full speed.

Starting off from a stop or at low speeds the vehicle loses all power. Engine stumbles and does not respond, when it happens it almost feels like the engine may stall. Pressing the accelerator and the vehicle will not move, then suddenly will start to go seconds later. This has almost resulted in a crash since the vehicle loses all propulsion unexpectedly. No warning lights. Took to the dealer twice and everything is -??normal-?? no codes stored.

Our vehicle loses power after initial startup when you first accelerate. We have had three incidents where we were pulling out from a stop sign or stoplight on a major road and you press the gas and the car shutters and doesn-??t move at all. All three times a car accident almost occurred. This has been reported to the dealer and they replaced the entire hybrid powertrain. The issue persists at random with no warning messages generated by the car. It also hasn-??t been replicated for a dealer to see themselves. It-??s extremely dangerous and has been reported numerous times on forums.
