Check out the 2001 Ford Escape. It has been on sale for less than 6 mos. and is the subject of a fifth recall notice...not TSB....RECALL !
Dealers have been instructed to hold off all test-drives and sales until a potential windshield wiper flaw can be repaired. Prior recalls in it's short life include steering wheels coming loose, improper rear wheel hubs, leaking fuel lines, and a cruise control malfunction that could cause the throttle to stick.
Also DC is recalling 769,000 Dodge and Chrysler Minivans to reinforce steering wheels that could separate from the steering column. Source : Autoweek 12/11/00.
I hope I've brightened your day !!! Keep up the good work.
Thank a lot and keep fighting!

Although it's not a Maxima.....read "Technical Correspondence" on page 142 of the Jan 01 Road & Track. The article is headed "Shifting Killjoy.

One other piece of information you could provide me if you don't mind is your Repair Order number. That way, Steve would have something to refer to when he contacts Courtesy Nissan. By the way, I realize your Repair Order number may have been manually generated as Courtesy's computer system has been down since Friday afternoon.
Thanks.

"Question: I have a 2000 Mercury Cougar V-6 with a manual transmission. When the accelerator is released while shifting, the engine speed will drop only gradually. To obtain smooth upshifts it is necessary to keep the clutch disengaged for about 1.5 seconds to allow the engine speed to drop to the transaxle speed."
"I have spoken with the factory and was told the engine-management computer keeps the throttle open during shifts for emissions-control purposes. The dealer told me my engine is operating within the acceptable range. Needless to say, this detracts from the joys of manual shifting. A 1999 Cougar I drove did not exhibit this trait. Similarly, there is very little engine braking when decelerating with the accelerator released, so the brakes must work harder. Is there a solution? Or is this a common problem with modern cars?"
"Answer: The short answer is yes, this is common in modern cars. When the throttle is suddenly closed, a momentary burst of high hydrocarbon production ensues as a bit of rich mixture is trapped in the cylinders. By effectively not allowing abrupt throttle movement, this condition is avoided."
"Unfortunately, to an enthusiast driver it results in a maddening loss of precision accompanied by the many undesirable side effects you mention. The only cure would be to rewrite the computer code in the engine-management computer."
"Aftermarket chip manufacturers seem to think this condition is caused by an automatic transmission computer code being used in a manual transmission application. In any case, they had not done the research and development to locate whatever code is causing the "hung throttle," as they hardly had any call to do so."
[The remainder of the article is specific to the Cougar.]
The article does not explain the underlying mechanics driving the fuel-cut condition, but it's clear that bigk200, Steve Thomas, and others are correct in pointing out a logic issue as the true source of the problem.

lurch forward hard compression braking etc."
This is exactly what my car does, but to me it sounded like the guy with the Gougar complained about the opposite symptom, which is, not having enough engine braking. Just my oppinion...
Joe
I agree with Joe's interpretation. The answer to the guy's question covers the entire spectrum of complaints even though all the possible complaints weren't listed. I'd be willing to bet that the guy has trouble maintaining a constant speed in 1st gear at low rpms just like you and I do.

The question is: How did they convince Ford to reprogram the ECU? Is it possible to do the same with Nissan?
I've read the past posts regarding the Cougar, and what was described is exactly the problem that we are having with our Maxima's.
The factory fresh versions of the Maxima uses an immediate fuel cut while loads of extra air is being allowed into the engine. When the fuel has been cut, the extra air serves to clear the engine of nasty fumes. That is why the engine goes from too much power to negative (compression braking) power.
The Cougar behaves similarly to the Maxima after the fameous "fix". The "fix" employs a small time delay before a fuel cut is allowed to happen. During this time delay, the engine continues to get loads of air (just as before the "fix"), but it also continues to get fuel for an extra moment or two. Eventually, the fuel cut still occurs, just not as suddenly as before the "fix".
Ok, fine... supposing for a moment that the fuel cut is necessary to complay with emissions, then I have to ask "why does the BMW's drive so well without any hint of the fuel cut problem"? I think BMW serves as proof that we shouldn't have to live with this problem.
Over and out.
without any hint of the fuel cut problem"?
it's the Ultimate Driving Machine don't you know!?, so what if you have to order them from the factory and wait 3 months to get one. I am sure you don't mind paying full MSRP and be treated like a dirt at the dealership unless you are wearing your Armani garb. Hey, so you have to take on another mortgage if god forbid it broke down...it's only money right?....small price to pay for no "fuel cut" problem...Go to the BMW 3 series forums and take a gander at the problems those folks are having and the grass may not feel so much greener on the other side.
If you ever get a Beemer stick to the 3 series since for some reason the 5 series seem to be more problematic (I should know I owned two 5s).

Does anybody have a clue why Edmunds nuked the webcite so all the links are dead now? That's really weird. Ok ok, they needed some "home improvement". But why did they change the location of the forum? That does not make any sense.
Anyways, I updated the web page so all the links at http://www.NissanMaximaProblems.com are now functional. Enjoy!

I've just sent another letter to MT. I indicated that "It appears that due to some miracle you've got the one and only unaffected (or specially modified) Maxima 2000 SE for your tests."
I also suggested they have a look at mine :-)
Let's press on the issue and let them know there IS a problem.
Kostya.
Car has about 1200 miles on it, observed the break in period and am getting about 24 MPG overall, maximum of 28.9 minimum of 22. I enjoy driving it greatly.
If your effort fails, I'm trying to think of what to do next. Does anyone have any contacts or names / addresses / emails / etc. for anyone at Nissan? Is it time to start a campaign?
Thanks,

Enquiring minds want to know.

By the way, I just test drove a 2001 V6 5-speed Passat and IT ALSO EXIBITS THIS BEHAVIOR. However, the 4cyl Turbo doesn't.
I have not posted in a while, but I'm still around.
No solution in sight! Nissan doesn't care about their customers. The customer is the enemy.

There are several people that tried this fix and swear by it.
BTW, anyone check out the new Subaru Impreza WRX? 227 HP, 0-60 6.1 seconds, etc. I've owned four Subaru's before this piece of junk Nissan, and I can't wait to see this Sube up close and personal. Only downfall is the size, but that doesn't matter that much for me.

I test drove a new BMW 528 5-speed last fall, and it did not have the problem that we all have with our Nissans and Fords. I guess you get what you pay for.
The service manager at my dealer tried to argue with me that the Maxima is an equal to the BMW 5 series... what a joke! I used to be a little critical of BMW, but this proves that BMW knows a thing or two about cars!
Don't take this the wrong way, I take offense at you calling one of the best cars that I've ever owned a "piece of junk". If your Maxima brings you that much displeasure, sell it, and spare yourself and everybody else the aggravation.
The Sube WRX certainly has the performance, although the styling is awful. I can't get used to those oversized headlamps and fog lights, and the rear is just blah.
No one should have to pay so much money for a car and have it perform so badly.
I agree with Dave that the Maxima 5-speed is a "piece of junk". At least in regard to the engine controls system.
I have not sold my Maxima yet because I like the overall styling, the stereo, etc., and I also don't want to take the financial hit by selling it so soon. I normally keep cars for a very long time, but this Maxima will gone in a heartbeat when I see something I like better.
True the Subaru WRX is nothing to write home about, but I don't think Subaru has ever had much in terms of styling, except for maybe the SVX which was quite unique. I look at it as "bang for the buck". I also feel bad for the A/T Max owners, as their trans problems have now expanded to 2-3 shift problems as well. But, a TSB was issued right away, due to the fact that Nissan knew this would cause tranni damage later on and had to cover their behinds.
If I get lucky and dump my Max somehow, I might post my FSTB and Razo pedals for sale, so there's always hope that I succeed!!

Here's what you do, drive your Maxima to the Bronx. Get out of the car, leave the keys inside and take a taxi home. The car will be stolen, and if you have gap insurance it will take care of the lease. BINGO...hopefully the police will never recover it.
Ok, so that's insurance fraud..
NOTE TO THE MODERATOR: I am kidding!.
Seriously, I feel your pain...nothing worse than being stuck with a lease with a problematic car...I have the same disgust with our Toyota Sienna which unlike most Toyotas it was built with bubble gum. Other than my scratch magnet black paint job I utterly enjoy my MAX SE A/T.
Peace,
Speed
BTW....I test drove the 5 speed Maxima, and I decided against it because I thought the clutch was too light, the throws were too long and vague. So, I partly agree with you that the 5 speed tranny of the Maxima is not a good one (at least not for my taste). Ofcourse there are those that think the Maxima 5 speed tranny is just perfect, and just like me didn't even notice the "fuel cut" issue at low speeds.
Enjoy the Beemer (when you get it)

Most of the 5-speeders who like to chat on-line about their cars are people who drive hard. The harder they drive (all on or all off the gas pedal), the less they will notice the "fuel-cut" problem. Perhaps thats why so many think their car is great.
