Greetings-
My Genesis is really starting to irritate me. The first time I brought home my car and my wife took it out, she came back and said:
"How come it doesn't go when you push the pedel down". The delay in this car is crazy. You have to half floor the peddle to get going and then it is too jerky.
Anyone else experiencing this delay? Is this something the dealer can re-program?
Thanks,
CLE
You need to explain to your wife that the Genny is a 'drive by wire' car; that is, your foot does NOT directly control the throttle via a cable to the throttle body flapper...rather, your foot CONTROLS the gas pedal only. It's set up with a spring so you get a SIMULATED feeling of MASHING down on the gas, demanding more power and higher RPMs. What your foot does is move the pedal's sensor that in turn tells the CPU you have demanded more RPMs. That in turn, has to be interpreted by the CPU and then sent to the engine, and then sent to the automatic tranny (which, by the way, is an 8 speed and is not a maze of hydraulic valves like the old school autos but electronically controlled and switched) and THEN it downshifts into the necessary range your foot has demanded. Hence the 'delay'...either from a dead stop, or that 'slight' delay when you mash the pedal to 'kick it down'..... it's just the nature of the beast now.
Here, let her read this...."drive by wire" or "electronic throttle control"...
It's essentially the same thing pilots have been using on wide body aircraft for years (fly by wire)....

The throttle cable has almost become
redundant on today’s motor vehicle. The drive-by-wire system is by no means a new concept as it was introduced by BMW on their 7 series range back in 1988. The system BMW use is referred to as EML (German term for
electronic throttle control). The system has now found its way onto other vehicles with humbler routes and can be found on base models. Historically a mechanical linkage between the accelerator pedal and the throttle butterfly has always existed, be it via a cable or via rods and linkages. These have now been replaced by sophisticated electronic control modules, sensors and actuators. This system is also referred to ‘Fly-by-Wire’.
There are several reasons why electronic throttle actuation is preferable to a conventional throttle cable:
The vehicle’s on board electronic systems are able to control all of the engine’s operation with the
exception of the amount of incoming air.
The use of throttle actuation ensures that the engine only receives the correct amount of throttle opening for any give situation....
[Presumably we are too dumb to know THAT]
The optimisation of the air supply will also ensure that harmful exhaust emissions are kept to an absolute minimum and drivability is maintained, regardless of the circumstances. Coupling the electronic throttle actuation to the adaptive cruise control, traction control, idle speed control and vehicle stability control systems also means
finer control can be achieved.
The use of such a system has advantages over the conventional cable version by:
*Eliminating the mechanical element of a throttle cable and substituting it with fast responding electronics, reduces the number of moving parts (and associated wear) and therefore requires minimum adjustment and maintenance.
*Greater accuracy of data improves the driveability of the vehicle, which in turn provides better response and economy...
[I'd dispute the "better response' statment, though]
Unfortunately it's something the dealer won't 'program' your car to do... and I got a message back from these folks that testing for the 2012 Genesis 3.8V6 is not completed...yet:
