Filed Apr 22, 2021 · Acceleration, Transmission · MN

My car will jerk as I'm driving rpms going high while no speed is picking up. With jump out of gear when at stop light. Loud grinding noise from tires could have foot all the way down on gas petal and go no faster.

At 28000 miles the transmission started shifting erratic, the dealer reprogrammed the ECM and covered up the problem until the warrant ended and the battery failed at which time the car reverted back to default and continued to buck and jerk until the car reached highway speed. This continued until the transmission finally failed during operation on the highway on 3/5/20. The ABS module just failed during low speed operation for no apparent reason. Also the car indicated that there is an electrical problem even though all electrical components are in good operational condition. This error comes and goes constantly at any given time.

Takata recall while my vehicle is in motion, & when I stop at a stop light, it's suddenly shuts off. This has happened several times while on the highway at highway speeds, & on city streets at normal speeds. It has proven dangerous several times. When I put the vehicle in reverse, the vehicle jerks very hard. Also when I drive for more than 6 to 7 miles at highway speeds, a tire pressure sensor comes on.

Seat moved back for "easy exit" all vehicle components shut off and vehicle brakes locked up in the road then cut back on by itself and transmission jerked into gear like someone rear ended us! Very scary and unsafe with my 10 month old in the vehicle!

Transmission jerks . Have that crack in middle lift gate around emblem like I see everybody has . Lift gate window bolts rusted and one broke in half on the driver side back lift gate at top back window it cracked in half didn't know that when I noticed my warning light saying hatch was open I didn't noticed anything went too open and try to shut it and when I lifted open the door the glass fell out and bent the hinge that supports the whole rear glass I grabbed glass held it till others came to help me in parking lot glass was heavy im tiny petite girl so thank goodness for people who came to help me at store it was just hanging there and the other side was just as bad just didn't break in half at that point yet thank goodness or I think the whole thing would have fell to ground and shattered .very expensive to fix at a dealer so my husband order parts at store and online for a lot less and fixed it himself so that's all fixed now. . Right after that we noticed same kind of car as our with same problem only they had it all duct tape and stuff to keep it together (probably because they found out how expensive it is to fix) I didn't think that was safe at all either. My cruise control stopped working had it replaced during warranty. My air conditioner sucks . Just last week the newest thing is my trunk lock wont open no matter what I do . I can only open the lift gate window that's it. But the whole back door wont lift open. Lock wont budge to open don't know why?

Two problems...first whenever I shift into reverse there is a hesitation and it takes longer than it should to reverse. Im also experiencing a jerk before I come to a complete stop. Second ..the back of my lift has a crack from the bottom of the window to the mercury symbol and then it continues down under the symbol. I've done some research and there re lots of others with these same issues. I only have about 70000 miles on it.
