Replying to: dmathews3 (Jan 06, 2007 8:19 am)  Aside from class action suits...I thinke if all of us make it a point to RATE the CAMRY LE in as many places as possible...this might help. By the way, any suggestions as sites where we can rate the camry to reflect this serious problem?

Replying to: neil1aa (Jan 06, 2007 12:31 pm) First, the only Toyota I own is a Prius. But I do have a 2001 AWD RX300 which exhibits the earlier symptoms resulting from the revised shift pattern/schedule adopted late in the last century as a safety measure. Seemingly on all Toyota, Lexus, Ford and VW FWD vehicles with automatic transaxles. At least those are the marques wherein complaints of 1-2 second throttle lag or downshift downshift delay/hesitation problems can be most easily found. My solid suspecion is that sometime late in the late century, say 1995, the automotive insurance industry approached the automotive manufacturing industry with the news that statistically FWD and front torque biased AWD vehicles were proving to be dramatically more hazardous(***) in foul weather conditions than their RWD and rear torque biased AWD counterparts. The obvious message being: "either fix what's wrong or we will start charging a premium to insure FWD and..., vehicles." Another obvious point along this line is like the over-confidence drivers of 4WD/4X4's get in foul weather so do many FWD owners due to the extra traction provided by the engine weight being over the driven wheels/tires. But that wasn't the major issue. Engine compression braking on a FWD vehicle can have a really adverse affect on vehicular control on a slippery roadbed surface. Even more to the point the anti-lock braking system can be made non-functional due to engine compression braking. So nowadays almost all FWD and front biased AWD vehicles with automatic transaxles will UPSHIFT upon a FULL lift-throttle event. That leaves you in coastdown mode in to high of a gear ratio should you suddenly have need for quick acceleration. Because the engine is now at idle and with the trnasaxle having just completed an upshift there is now insufficient ATF pressure/flow to complete the required downshift quickly. So the manufacturers have chosen to use DBW, e-throttles, to delay the onset of engine torque developement until the downshift can be completed. *** Ford Motor Company has just been awarded a patent for two techniques which appear to directly address this issue. The first of these involves substantially reducing the level of regenerative braking on a hybrid vehicle when the OAT declines close to or below freezing. The second involves disabling regenerative braking the instant the anti-lock braking system activates so as not to interfere with ABS activity. The only vehicles in production to which Ford could currently apply this patent are both FWD or front torque biased AWD.

Replying to: wwest (Jan 06, 2007 1:51 pm) This isn't directly related to the topic at hand, but I had to respond to your comment. There is NO evidence that front-wheel-drive vehicles were involved in a greater frequency of crashes in inclement weather conditions compared to rear-wheel-drive vehicles. Therefore, the insurance industry never approached the automotive industry demanding changes. If there were such evidence, there is no doubt in my mind that the research arm of the insurance companies, the Insurance Institute for Highway Safety, would have publicized a study to that effect. If you can provide a link to ANY research showing FWD vehicles are so dangerous in bad weather, I'd like to see it.

Replying to: mvperez4jesus (Jan 06, 2007 5:30 am) That said, it is the Camry that has been the best selling car in the US for 9 of the past 10 years, not the accord. Should you be interested in the Camry, and are looking at the I4 5A, just make sure it's built after October. As for the V6 6A, I'm still not aware of anyone with one built in the past few months that has reported the RPM flare. |

Replying to: 210delray (Jan 06, 2007 3:28 pm) Can you spell "parasite"? Can you imagine what would happen to FWD automotive sales, let along used car values, assuming what I surmise is true and the information became publically available from a source considered as reliable as the IIHS? "...There is NO evidence...." Not only does the Ford patent speak strongly to this issue there is clear and certain evidence that Toyota, Ford, and VW have "stuck to their guns" in the face of fierce public outcry about the adverse affects of these 1-2 second downshift delays. Why wouldn't they simply revert to the old tried and true shift pattern/schedule? For Toyota it seems to have begun with all the reported premature transaxle failures in the 99 RX300. The most real indication of this being a problem was with the 2003 Camry transaxle as recorded via the TSB issued in the spring of 2003. And as you can see those exact problems continue with the 2007 models. Eight years is an awfully long time for Toyota to take to correct a design problem. Don't we ALL know that these transaxles used to downshift upon full lift-throttle events? Other than the aforementioned safety issue why such a drastic change in the shift pattern/schedule and seeming only for FWD models? Because anyone having ever driven a stick shift FWD vehicle on adverse roadbed conditions knows full well the hazards of downshifting to slow or stop. Best to use the e-brake lightly.

One must also realize that the Camrys good sales figures are in part due to their fleet sales to rental companies like Enterprise, Alamo & others. I've yet to see any Accords in rental fleets, so the Camrys sales numbers aren't really truthful in that regard. Having owned 2 in the '90's, they were both competent "appliances" with lousy brakes. And with the teething problems at Toyota of late, I'd definitely wait until these latest acceleration problems are resolved. It reminds me of Toyota's attitude with the "oil sludging" problem. Toyota blew it with their somewhat slow response of even acknowledging the problem. Seems like history is repeating itself again. Sad too. What's happening with the auto industry of late. Why can't any company just produce a trouble free product that anybody can afford to buy & own? I'm at a loss on this question...! The Sandman

ALL 2007 TOYOTA CAMRY OWNERS: The evidence is out there. The dealerships know of the problem. There is definitly a transmission problem with their new line of Camry's. Most importantly, the transmission issue is an extremely dangerous safety issue for all of us. We all need to bond together and start writing letters to Toyota, continue giving bad reviews to the new Camry, complain to the National Institute for Highway Safety, write letters to our senators and congressman. We need to force a transmission recall among Toyota and place pressure upon the company. Thousands of people read this forum and Toyota has a team developed to read our posts and figure out how to do damage control through the press. If Toyota will not issue a safety recall for the 2007 Camry transmissions within the next 4-6 months, a class action lawsuit will have to be formed and will be available to all 2007 Camry owners.

Replying to: wwest (Jan 06, 2007 4:46 pm) Then you said, You can be certain sure that the automotive insurance industry is just as "beholden" to the automotive industry as are the automotive magazines and your daily newspaper. Can you spell "parasite"? So which is it? Is the insurance industry able to stand up to the auto companies and say it's time do something about these "hazardous" front-wheel-drive vehicles? Or is it a "parasite" that feeds off the auto industry? All your statements about how automatic transmissions upshift, downshift, and hesitate are beside the point. Where is the evidence that FWD vehicles have been "dramatically more" hazardous than RWD vehicles in bad weather conditions? Can you point to higher fatalities and injuries? No, all you can cite over and over are Ford's patents which deal with regenerative braking, which is used at present only in hybrid vehicles. This is my last comment on the issue, although I find it curious that if you think FWD and "front torque biased" AWD vehicles are so hazardous, why do you own both a Prius and a Lexus RX? Shouldn't you be driving a Crown Vic and a Tahoe instead? Now, let's return to the topic at hand, before the hosts step in and ban this side thread.
