Please help! I have spent thousands of dollars on trying to figure out why my car is stuck in limp mode. I had both front axels repaired and when I got my car back it wouldn’t go over 40mph. It has no communication with engine control module and transmission control module (this was before limp mode and currently). Electronic parking brake automatically engages every time I go to drive and press the gas. Hard shift from park to drive or park to reverse. I sent it back to the shop and had transmission fluid checked, fuses checked and sensor for speedometer and anti lock break replaced.

Um....axles wont cause limp mode......this is an odd one.

ikr, do you have any ideas?
