Loss of power with 3 lights on (Slip, VDC Off, Service Engine Soon)

2004 Murano SE, 65K miles, still under extended warranty

I was driving on local road about 40miles/hour in a hot afternoon. Suddenly noticed lost of power, and car slowed to about 20 miles/hour. Pressing on the gas could still move the car at 20 to 30 miles/hour, but definitely feel the force from the engine is only 30% or so of normal power.

At this point, noticed 3 lights on the dash board: Slip, VDC Off and Service Engine Soon.

I kept the car going at this slow speed for about 0.5 mile into a parking lot. Turned off engine and after 3 min. turned back on. Everyything seems to be fine now. The Slip light and the VDC Off light are off as well. Only Service Engine Soon light is on. Drove home with no other issue at all.

I am to try to call the dealer to schedule an appointment. Any insight on what might have happened and how serious this could be?

One optimistic scenario could be somehow a slip happened (hot road, hot tire, who knows what), triggered Slip light which forces VDC Off as well. Then the Service Engine Soon light is on (this is supposed to be the light that will go on anything goes wrong?).

A bad scenario could be CVT is starting to fail? My extended warranty will expire 6K miles later. So in this scenario I really appreicate any thought to get down to the bottom and fix it for good now. Next time this recurrs I will be out of warranty...

THANKS!

I would have gone to an AutoZone right away to see what the codes were. I have a code reader at home so depending on where I was would have been the place I would have gone.

If it were the CVT the AI think the CVT light would have gone on.

Keep us posted.

Sounds like you tripped some failsafe mode for the computer which limited engine power. My guess its either an electronic throttle problem or (hopefully not) a transmission issue.

Lots of squeaks and rattles.

Hey guys...would this issue fall under the same CVT overtemperature condition that others have experienced?

Result

Turns out to be a failure in Thorttle Body Assembly. Here is the diagnosis on the paper:

"Performed diag and traced to internally failed throttle body assy. Replaced assy and performed idel relearn and working".

THere is another note saying "found code p2135. found tps sensor inop. recommend replace and recheck". Anybody know what p2135 is, and what is "tps sensor". I am now asking myself if this is a seperate problem that they have not fixed, or it is part of the "failed throttle body assy"?

This throttle assembly somehow falls under factory warranty still (I heard something like 70K miles or 10 years I think), so all costs were paid by Nissan.

I had the DTC P2135 (throttle position sensor) on my 04 SE several years ago. I retrieved the code and then reset the check engine light (MIL) in my garage using the accelerator pedal method. As I have learned with all of my Nissans over the years, reset the code the first time you get it, and see if it returns. Many times it's a fluke and is nothing to worry about. That was the case with my Mo's 2135 DTC. The code never returned.
