I have an automatic car is doing funny things
First when selected Drive or Reverse it would just jump back on its own into Park.
Now its not doing that anymore.
Now when i select reverse it goes into reverse and as soon as i get close to something it was sound an alarm, but when i select Drive it goes into drive and goes forward . the alarm disappears but the reversing information is still on the dash screen even when i put in Neutral.
Hope i can get some help from you or someone on this chat
