When I drive over 50 mph and stop, I get messages 'engine system default' and 'transmission system default'. The car slows down, but does not completely die out. I turn it off and am amble to restar


Sounds like you have lost overdrive. Most cars go into to limp mode with engine and transmission problems. Limp mode is reduced engine power and the transmission only shifts to certain gears. Keeps people from totally destroying the drive train.

WHAT COULD BE THE PROBLEM WITH MY 2000 GMC YOKON XL WHEN A REDUCED ENGINE POWER MESSAGE COMES ON THE MESSAGE CENTER


A sensor within the car's computer system has detected a possibly major problem. The system then puts the engine into "limp mode" so that it can be driven to a repair station. Driving in this condition will only increase the damage. Highly recommend you take to reputable mechanic immediately for computer diagnostic.

Cvt light on indicating over heating. Stops car lets it cool down and then completes his trip. Dealer could not identify problem or diagnose the problem.


I do not know why your local Mitsubishi dealer cannot figure this one out. What you are describing is a known problem for which Mitsubishi has published a Technical Service Bulletin (TSB).

The problem is caused by incorrect transmission fluid levels and there is an updated dipstick included in the fix.
MITSUBISHI TSB REFERENCE NUMBER: TSB-10-23-005

You may also want to talk to your son about heeding warnings from your vehicle's onboard computer system. When the CVT transmission begins to overheat, the CVT light will come on, a warning chime will sound, and the words "SLOW DOWN" will be displayed in the Muti-informational Display. This will occur LONG before the vehicle goes into "REDUCED POWER" mode. If he would slow down as he is being told to, the warnings will extinguish themselves as soon as the transmission fluid temperature drops to a safe level (which it will, if he slows down).

REDUCED POWER MODE is like an angry parent...."OK, you don't want to slow down like I told you to do, and you are going to destroy my transmission by ignoring my warnings, so I am shutting you down!!! You won't slow down, so I am slowing you down! Now, if you do not want this to continue, then you better start listening to me!"

Similar things will happen if you choose to ignore engine control or Brake/Traction Control warnings. The old days of ignoring warning lamps and running around with your dash lit up like a Christmas tree are over. There is a new sheriff in town called REDUCED POWER MODE.

There is a whirring noise and the gears don't seem to be kicking in. The car is an slk automatic


It seems that your clutch plates have worn out. The automatic gears system uses a centrifugal clutch which automatically engages as the engine rpm increases. If the the plates are worn out, it will make a whirring sound as you rev the engine & there will be a loss of power transmitted to the wheels resulting in slow pick up of speed. Get the clutch plate assembly replaced.........sodeep

Engine power reduced


Locate the IP to body harness connector, which may be located in and around the left hand kick panel area or inside the IP. Check to see if there is a water leak into the area and repair as necessary.
