Trans.Fail Safe Prog.
 

04 x5 4.4l error message Trans.Fail Safe Prog. but the transmission shift perfectly normal and drives like new only issue i have is the temp gauge goes to RED then back to halfway. the speedometer goes dead then works again and the rear suspension is lower than the front.

Not sure if this would apply to the X5 or your car specificially...but I had encountered something similar on my E32 (735iL), and it turned out to be a faulty speed sensor.

Gonna guess and say the battery needs to be replaced. You get all kinds of happenings with a week battery, its due anyway if its the OG battery.

battery alternator and starter was replaced less than 2 months ago.

:iagree: sounds like the battery.

It has to be battery, alternator or you have some odd electrical issue going on with your X.

Are your DSC lights on? Brake, ABS? It might be your DSC module for which this happened to me last month and i got it repaired. Before getting my module fixed i got my brake sensor, speed sensors changed but still no avail. So my mechanic told me the DSC module was bad.

Yes all the brake lights are on...i just replaced the abs unit too and no luck on getting rid of the warning lights prior to the trans fail safe prog. came on. how much did the DSC module cost?

The repair was $300 at modulemasters.com.

I had the same problem with Trans Failsafe Prog and now my car is dead. I have to jump the battery to start the engine. Do I have bad battery or DSC module? Please advise.
