UPDATE:
I have an 03 Murano, been a pretty reliable car since I bought it back in 2006 from a Nissan dealer in South Florida. I have approximately 130,000 miles on it. Recently, I had the transmission service fluid change since it was due. Even though I didn't have it done at a dealership, it was serviced by a specialist who used the fluid required (watched to make certain). For a few days everything was running normal, then suddenly the engine (RPMs) revs up and it lunges forward.. but doesn't move forward--almost as if i had the brake on holding it back from moving. It would lose power, but not stall out. Even when I depressed all the way down on the accelerator only then would the car begin to move.. very, very slowly pick up speed maybe not going past 40-45 on a highway after 10-15 minutes of driving.
I found out that if shut off the engine and restarted my car it would operate as if nothing happened. Problem is, it does it all over again, I noticed this especially when it's warmed up. I took the car to a mechanic close by (not the same one who changed by fluid) since he had a former Nissan mechanic familiar with Muranos. My car had sat in my garage for 3 days so it was cold and during a 15 minute drive to drop the car off I didn't experience the problem I had been having.
After they checked it he came back with engine fault code # P1778, which he explained was "step motor circuit problem". He said best to take to a Nissan dealership (aka, "stealership") since it might require in-depth ($$$) transmission work which only the dealership could do.
After reading through the forum I was surprised to see all the issues which sounded so similar to mine--all revolving around the CVT transmission for my year Murano. I'm now going to have to tow my Murano into a dealership to have them look into the problem. From many of the post I've read on CVT transmission, specific to the 03 Murano's, I'd like any advice on what I should suggest/explain to the dealership when I end up towing it in. Below is a list of things I am going to point out to them to keep them from (ripping) overcharging me, or not misdiagnosing the initial problem as an inflationary sales tactic.
-----------------------------------------------------------------------------------------------
1.check air intake piping has been performed (past recall) and the main breather hose is loose which might cause this problem.
2. throttle position sensor problem (I believe this TPS is the sensor controlling the throttle body valve.) or maybe a TCM sensor issue. from what I've read the pressure sensor is located either on the CVT, or inside the CVT which is inexpensive itself, but expensive to replace since it means tearing apart the transmission.
4. check out the transmission valve body that will goes bad after a while.
5.crank sensor failure problem.
------------------------------------------------------------------------------------------------
Could this also be related in some way to having the transmission fluid changed and a sensor inside (TPC) and became clogged?? If so, is there an inexpensive way to fix it?
What I want to avoid is the service (salesman) adviser to recommend to replace the transmission seals thinking it might do the job, (for about $1500) if not they would look deeper for something else (to bill me for..$$$)
Any other suggestions, or help especially to which Nissan dealership I should take my car to who is honest, reputable and has experience (a tough task, I'll settle for 2 out of three) with this type of problem who is located in South Florida would be greatly appreciated.
Of course, I will update my problem (good, bad, etc) with details to help others ( of which there might be many) out there who might find themselves in this same predicament.
Thanks in advance for advice/help on recent experiences similar to mine would be appreciated!
