I noticed that when got to accelerate from stoping that car won't go. When I hit the gas the vehicle moves only a little and if I push my foot on the acceleration peddle harder and all the way down the vehicle actually slows down. It happened this morning on city street roads not going any faster than 45mph. The only way to get it to go again is taking my foot off the gas peddle and re placing it and it then will go back to accelerate as it should when I press the gas peddle. I have gotten it looked at suburu dealership and they were unable to figure out the problem. It happened to me twice this morning. Once when turning off my street taking a right trying to accelerate to 25mph and then another when trying to accelerate after a stop light on a 45 mph road. I will be reporting it from now on every time it happens. This is very unsafe, it could easily cause an accident. Thank goodness no one was right behind at those moments when I went to accelerate.

The contact owns a 2015 Subaru Xv crosstrek. While driving and releasing the brake pedal, the vehicle hesitated to accelerate for approximately four seconds without warning. The vehicle would then resume normal operation. The failure was experienced several times. The vehicle was taken to servco Toyota honolulu (2850 pukoloa St #200, honolulu, hi 96819, (808) 564-1100) to be diagnosed, but a failure code was not found. The vehicle was also test driven, but the failure was not duplicated. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 19,000.

After removing car from garage, while slowly driving uphill in alley (less than 15 mph ), car accelerated on its own while my right foot was in the air on the way to brake to slow down for a turn. The car moved & sounded as if accelerator had been depressed, but it wasn't by the driver! I was able to stop the car with the brake, but unintended acceleration caused car to overshoot where I wanted it to go by several feet. It didn't collide with anything. I heard a "thunk" below car a couple of seconds before the acceleration. I brought car to dealer at earliest appointment - Oct. 11. they suggested it was the continuous variable transmission. I knew car well enough to know what I experienced was not how cvt operates & insisted on speaking to supervisors. They helped me open an investigation by Subaru. I gave Subaru written consent to access the car's black box. Their inspector (from Bosch automotive services) downloaded black box & car's other computers, performed a physical inspection & test drove. He said it was unlikely to be caused by cvt or the cruise control, & found no damage under car. On 11/10/16, I got E-mail from Subaru that no defects were found, no diagnostic trouble codes were stored, & "the vehicle is operating as designed." I called the signer, who stated the "impact of the acceleration was not enough to store." She refused to provide me copies of the computer printouts or any other docs from investigation, claiming they are proprietary to Subaru, even though the data, as part of car, belongs to me! while car was out of service over 30 days, lemonlaw didn't take case as no defect was found. I understand intermittent electronic throttle control problems don't leave dtc codes. Don't know if I can trust this car, as malfunction's cause was never found. NHTSA should issue regs on electronic throttle control safety as owners can't sue!
