Hello,

When a vehicle is in limp mode, it will have the service engine light illuminated.
Is your check engine light on? If so have you retrieve the codes?
This can help us point to the right direction of why it is in limp mode.

Here is a guide of how to check for codes:

A vehicle usually goes to limp mode to protect the vital parts, like engine or transmission. You might find these articles on limp mode helpful:
