Can anyone tell me why when it is humid, rainy, or over 80 degrees out, that my car acts like it has a shifting problem? When I give it gas, it hesitates, and sometimes jerks. Also, when giving gas uphill, it almost acts like it's in 5th gear and might not make it up. This has been happening for over 2 months. 2 weeks after it started happpening, my Air Bag light came on and has stayed on since. Someone looked my car over and he thinks it's a computer problem. I just want to know if anyone has had this problem and what was the fix, or if someone knows of a fix. Thanks in advanced.

 

Underneath the dash, there is a data link connector... have dealer plug the GDS into that data link connector and scan the modules for codes and see where you are..

SRS has nothing to do with driveability issues,,, 2 independent systems.

On the SRS, I will venture a buckle high resistance code for 1 of the front seat belt buckle exploders, or a 1448 mat defect at passenger front seat.

On the drive concern, maybe 2106, 2135 and 1295 as a wild guess.. transmission codes, no common codes for NF Sonata
