I really didint want to start another thread complaining about the Max, but i guess this one is more a search for some answers.

I started a thread a while back regarding my problems i have been having with my car, and it boiled down to an endless list of crap. So, i had my car misfire, and the dealer blamed it on the fact that i was driving the car on low fuel. So after posts and posts of complaining, i gave up and just accepted it. . but i guess i don't look at my car like i did before.

Anyway, again my car is a 41K 2005 Auto Maxima, maintained the way it should be, Mobile 1 every 5K or less, just waiting for the larger maintenance.

So i get my car back, and i have been noticing things that i havent noticed before. I dunno if these traits have always existed, or have i become paranoid since my car spasmed on me with the cylinder misfires.

For one, the car shakes now. . .. during idle at a stop light..i feel the seat shaking and vibrating. . . .though minor, but it is now noticeable. . .and happens around 50 percent of the time. While driving, the steering wheel shakes as well, sometimes vigorously and sometimes mildly. Thirdly, i have been watching the RPM on my car, and i have noticed something very weird. Whenever i step on the gas, the RPM goes up. As i release the pedal, the rpm drops .. . . then drops again, and bobs up and down. . .literally bobs up and down .. . .before stopping again. . . . .For example, i press the gas, and it revvs to 3K. . . i release, and it drops to 2K and stays there for half a second .. .then drops again to 1K. . . and bobs up and down. . .and stays at 1K. . .. .

These are all very very weird things going on with my car, but the engine light isnt going on so i cant even bring it back to tell the dealers of a problem. also, the transmission is VERY unsmooth now, but not enough to point out as an issue .. . .honestly i really believe my Max is sick .. . .i dunno what it is, but i am SURE there is something. . either with the tranny or the engine or the cylinders, but SOMETHING is wrong .. . .

If there are any competent mechanics or anyone knowlegeable i really need help. I am way too sick of the dealership, and the better ones seem a drive away, and i would be risking an entire days away waiting for an answer that might not come to me .. . .if anyone has any advice at all .. . .all help is appreciated. . . . .

 

I don't know what could be the problem, but I would get your max into the dealership just to create a paper trail in case you get past your warranty and all hell breaks loose.

 

low fuel as in low grade or tank too empty?

 

Low Tank .. . . thus sucking up sediment and crap into the fuel system from the bottom. .. .

The shaking is of least important.
I really worry about the erratic RPM movement. . . . .its starting to worry me more and more ..
and as with the transmission, im just gonna drive the living h@ll out of the car until it breaks .. . . .

 

I'm no expert but it sounds to me like rpms are moving because the car is down shifting as you slow down.

 

Make sure you have everything documented in a nice little folder....

 

Hmm downshifting. . .wouldn't that raise the RPM instead?

Yah i kept all my invoices for all the billions of times i went into the dealer.
I do have warranty, but right now that extra bit of cash to get it fixed at some other place seems much more worth it than bringing it back to the "free" dealer that doesnt fix crap for me. ...

Has anyone run into this engine issue ever?

 

I been fortunate, im now at 82k and never an engine problem....id be shocked considering its supposed to be such a wonderful motor (and I agree). Sounds to me like alot of bad luck, id put it out to the pasture if I had to deal with alot of **** liek that.

 

The vibration and trans issue would almost lead me to check the motor mounts. It would make sense anyway.

 

d@mn .. . .aright i guess its back to the cursed dealers. . . .
i'll try for saturday

 

Sorry for the bump of this thread, but I don't have enough posts to start a new one.

My 04 Maxima has 70k miles on it.

I have an odd problem. If I drive my car through snow/slush the rpms will drop from 2,200 to 500, then pop right back up to 2,200. This has happened 5 times, always while driving in a snow storm. The car drives flawlessly in all other weather conditions. Pushing harder on the gas peddle does nothing. In fact, I seem better off if I remove my foot from the peddle, and then re-apply.

This is a dangerous situation as it happens on slick roads, and when the rpms pop back the wheels spin.

Any ideas?

 

Sounds like it is your stability control system that is engaging. If it is, it is functioning properly. Read your owners manual or do some research regarding.

 

OP, not sure what is the problem, however go to another dealer. Sometimes another one will do things the first wont do.

 

the rpm shift, are you talking about if you are in 3rd gear and traveling at a consistent speed and you LIGHTLY step on the throttle that the cars rpm will jump a few hundred while never leaving the gear and not accelerating equally with the rpm shift? if so this is common. short story the maxima has the ability to "get ready" for the downshift by speeding up the engine regardless of the speed, gear, or current rpm. they do this so there is less lag when you stomp on the throttle.

it works kinda like the aston marten vantage.. when downshifting the car will match the road speed so there is no jerk. the car also "spools" the next gear so when you are under hard acceleration, the shift time is quick and the result is as much power as fast as possible. the aston also has the ability to "think" and predict your next gear change. its very interesting.

now the aston marten uses a computer and a very complex transmission to do all this, the maxima uses only mechanical means for this, and it is very very slight. Its just a luxury feature in the AT to make using tiptronic easier and acceleration deceleration smooth. this is a feature that a lot of cars will begin to adopt.

 

Nice reply 20eggs. I've noticed this recently a few times and I thought it was my trans starting to slip. With your explaination I don't need to worry. Thanks.

 

My tranny does the same thing and had me freaking out. I put it in triptronic and it didnt do the same thing. Thanks Twentyeggs it makes perfect sense now.

Reficuliu: see what happens if your in third with triptronic. If it acts the same then it might be a problem. I was same way and got paranoid and found problems that didnt exsist. My shake was tires. Rough Idle was only at realy low RPMs and in gear but I felt that in most of my friends cars too. These guys are right though, your under warenty so get documents on everything so you can show it as pre existing.
