So, if it's associated with RF interference and the throttle electronics, why does it tend to wait for 10K to appear and why does replacing the CVT appear to correct it?bluebonnet said:Hello All,
Sorry (Christine, Yamamoto, et al) to hear that you are having surge problems.
I have had my new(2009 SL) Cube for 2 days now. Now you've got me worried. I'll be on the lookout for any weird behavior.
I wanted to ask the group about the throttle control as it pertains to the surge problem. Many cars today (including our Cubes, Honda Accords, Toyota Camrys, etc.) use a "drive-by-wire" accelerator pedal. In other words, the pedal is essentially an electronic position switch whose position is transmitted electronically to control the fuel. Like any switch, noise or some other deleterious artifact, could corrupt the electronic position signal. (think of an old radio volume control knob that creates static whenever you adjust the volume).
I have read elsewhere some speculation that this type of interference may be contributing to the Toyota problem. The Cube surge sounds eerily similar. I know a thing or two about electronics and can imagine a scenario where radio frequency interference could (at least theoretically) upset the normal operation of some control electronics.
So, could erroneous (eg - false) accelerator pedal position signals create the surge behavior?
Also, I would suggest that anyone encountering the surge problem to note their geographic position (they may be near a cell phone tower, etc), and note whether their radio, cell phone, was being used.
Just food for thought.
I am quite sure the reason is to get people to purchase a CVT vehicle who may be worried about this "new" Technology. when I purchased a new Murano in 2004, I was very worried about the tranny as replacement was $6000 I therefore elected for the extended warranty upon purchase which cost me an extra $1500.miata007 said:I think there are 2 reasons car company increases the warranty.
1. give people confident that a product is reliable/all the bugs have been worked out. (ex. Hyundai is confident about theirs so give people 100K warranty).
2. there is a problem (ex. the TL/Odyssey transmission. There are people who replaced their tranny 3x)
As of the cube, I am not sure which is the reason. Time will tell if this (surge problem) becomes a issue.
How many times have you had the surging occur? Mine done it only once for about ten minutes, and that was several thousand miles ago. ...... Nothing even similar since that day. .....Go figure ???MDracer76 said:Looks like I have this same issue..
Just over 15K on the odo, and 1.5 years of ownership...
