2017 Kia Sportage Power Train

Transmission stops drive ability at various times when pulling out into traffic it stops accelerating and the engine just revs high rpm’s until it slams itself back into a power gear. I have stalled several times recently pulling into traffic and was nearly involved in a wreck because a momentary lack of acceleration. This problem also hapoens when driving a steady speed it all of a sudden stops accelerating a d just revs the engine very high until it catches itself and regains the ability to have power.

The contact owns a 2017 Kia Sportage. The contact stated while driving 60 MPH, the vehicle failed to accelerate as needed. The vehicle then went into LIMP Mode with the check engine warning light blinking. The vehicle was taken to an independent mechanic who stated that the vehicle could not be diagnosed because the vehicle was under recall. The manufacturer was not contacted. The failure mileage was 64,000.

bad transmission. engine revs up but car isnt moving at all.

The contact owns a 2017 Kia Sportage. The contact stated while driving 65 MPH, the vehicle inadvertently stalled and lost power. There were no warning lights illuminated. The contact stated that while attempting to restart the vehicle there was an abnormal knocking sound and the vehicle lost power. The vehicle was towed to the dealer who diagnosed that the engine needed to be replaced; however, the dealer informed the contact that the repair would not be covered under the warranty since the knock sensor software upgrade was not completed on the vehicle prior to the failure. The manufacturer was made aware of the failure and stated that the knock sensor software upgrade was not completed on the vehicle prior to the failure and offered no further assistance. The vehicle was not repaired. The failure mileage was 95,079.

Transmission intermittently goes into neutral while driving causing engine rev, loss of ability to continue to drive/maintain speed. Very dangerous as you have to drift to the side of the road and put the transmission into Park and back to Drive to get it to engage again. Meanwhile you could easily be struck by another car trying due to sudden loss of momentum with no brake light warning or trying to maneuver to the side of the road with no engine power. Occurs every month or two. Dealer unable to duplicate multiple times. No warnings before it happens. There are at least 20 other reports of this on the NHTSA site. When will an investigation be opened? This has the potential to cause a serious crash.

TRANSMISSION WILL SUDDENLY DISENGAGE AND ENGINE WILL ACCELERATE TO 4500 RPM OR HIGHER. THIS HAPPENS WHILE DRIVING MOSTLY WHEN VEHICLE IS BETWEEN 25 AND 45 MPH. THIS HAPPENS SEVERAL TIMES A MONTH. THIS HAS CAUSED VEHICLE TO PAUSE WHEN SWITCHING LANES, ALMOST CAUSING AN ACCIDENT. THIS HAS HAPPENED MULTIPLE TIMES OVER THE LAST YEAR.

WITHOUT WARNING THE CAR DROPS OUT OF GEAR, THE ENGINE REVS. YOU HAVE TO TAKE YOUR FOOT OFF THE GAS FOR THE CAR TO GO BACK INTO DRIVE AND YOU CAN CONTINUE DRIVEING. THIS HAPPENS AT ANY SPEED.
