Replying to: venky_rk (Apr 18, 2007 7:16 pm) people with the 4cyl had been complaining of hesitation, and the V6, a transmission shift flare. it's possible your vehicle is affected by a long-standing problem going back years with DBW implementation on some lexus and toyota cars. search for hesitation here on edmunds and you'll find other forums marked read-only. with the 2007 specifically, some people with the 4cyclinder experience delayed accelerator response when merging on the highway, changing lanes, slowing to make a left-hand turn. ---- i suggest you start collecting some evidence to support your assertion there is a problem with your vehicle. one thing you could do, you could find a parking lot where it is empty using a video camera (with the time displayed) and you videotape the speedometer (so they can see your speed) wheel position (so someone knows you are making a turn) and tachometer (RPM indicator), while verbally explaining what you are doing and what you are experiencing. bring it to the dealership and show it to them, and have them ride with you while you duplicate the problem. tell them it is unacceptable and you expect an immediate solution. does the vehicle have stability control? it could be an issue. you could have a fuel pump problem or a loose hose or sensor. you could have a loose wire / ignition problem. whose to know. so it might not be DBW (drive by wire) or stability control. but first things first, get some objective evidence and go into the dealership prepared. doing so will show them it is unacceptable and you've got it documented right out of the gate. from prior posters, expect to be told everything is operating properly. if you feel your safety is compromised and you want out of a vehicle that hesitates because you are concerned about your safety, the safety of your passengers, other people on the road in your immediate vicinity, tell them. there might have been a TSB issued to reflash the ECM/TCM to improve the situation somewhat. you'd have to scan this forum and 2007 Toyota Camry Transmission Questions to check on this. good luck to you. |

Replying to: venky_rk (Apr 18, 2007 7:16 pm) A sharp turn, a fast one or accelerating turn especially, would imply the possibility of understearing or even slight actual understearing in which case the VSC might activate. You may even have roll-over protection in the system firmware or if one of the front tires slipped even ever so slight then TC would activate and result in your symptoms. In a tight, sharp turn the outside front wheel is already turning faster than the inside wheel and the firmware tolerance for wheelspin/slip may result in the ECU "thinking" that means the outside wheel is slipping and therefore activate TC. VSC, or even TC, activation might result in so slight a brake application as to be un-noticeable but the simultaneous engine dethrottling, and the rsulting recovery delay, would be VERY noticeable. Lose traction of/on the driven wheels of a RWD vehicle due to engine DRIVING torque and you still have the front wheels to maintain directional control with, On a FWD vehicle.... *** Traction Control firmware on a modern day RWD vehicle will apply moderate braking to the (DRIVEN) slipping wheel(s) but delay engine dethrottling to give the driver time to react. On a FWD the firmware differs in that it will simultaneously dethrottle the engine and apply moderate braking to BOTH front wheels. TC sensitivity to wheelspin/slip and reaction time is much quicker and faster than the driver could possibly be in doing EXACTLY what needs to be done, THROTTLE LIFT! Loss of traction, slight, or in some cases even impending, on/of the driven wheels on a FWD vehicle is so much more hazardous than on that of a RWD vehicle that the firmware design varies quite radically and in numerous ways/methods in order to most quickly return directional control to the driver.

I presume neither VSC nor TC will be completely "silent". There must be some tone or indication it is activating. If not, I would think that would be an issue.

I have a strange problem. When I bought my 2007 Toyota Camry SE with Navigation I remember cycling through the functions with the mode button on the steering wheel. It went something like CD/FM/AM/AUX. I remember thinking that the AUX input would be great with an ipod when I got one. Today I got my wife an ipod for her birthday with a car kit with the car charger and a 3.5mm plug for the AUX input near the 12 volt plug in the dash. I clicked the mode button and I could not find the AUX function. I plugged in the ipod and noting happened. I attempted to get the ipod to work for an hour and nothing. I called the dealer and they told me what I had been doing already. I am wondering… 1) has anyone plugged an Apple ipod into their Camry? 2) When you hit the mode button on the the stearing wheel does AUX show up as one of the functions? 3) Is there a chance the dealer updated my DVD Nav system without me knowing loosing the AUX function? 4) Should I reset the system to factory specs loosing all inputted info on the Navi system? Please help if you know anything about this. I know that this is a small problem but I would like to fix this myself if I can rather than wasting time at the dealership. Thank you!

The dash of my 07 Camry rattled like there was no tomorrow on my way home from work this morning. Wasn't even that cold out (50 degrees F). Quite a disappointment after having two TSBs performed on it! I guess Toyota's "anti-rattle kit" is just as flawed as the design of the 07 Camry's interior! Maybe I'll try disassembling the dash and filling it with silly putty...
