Automatic Transmission Control Module Problems of Toyota Camry

The car start showing signs of "brief shudder intermittently while driving under light loads between approximately 25 and 50 mph", as indicated on Toyota service bulletin t-sb-0034-14 (https://static. Nhtsa. Gov/odi/tsbs/2014/mc-10131827-9999. Pdf) and t-sb-0312-17 (https://static. Nhtsa. Gov/odi/tsbs/2017/mc-10146516-9999. Pdf), with Toyota's solution "the torque converter and engine control module/ecm (sae term: powertrain control module/pcm) logic has been modified to reduce the possibility of this condition occurring. Follow the repair procedure below to address this condition. " today 5/1/23, I have taken the car (91,079 miles) to Toyota dealership, and the mechanic recommended "transmission replacement (automatic): complete transmission with torque converter & reset values to relearn new transmission and drivers driving habits: $6,888. 17". I have called Toyota (800)-331-4331 explaining to Toyota representative the issue and referring to Toyota's service bulletin on this issue, with the hope the cost of the repair will be covered by Toyota, since this is a know issue for them. However, I was told that Toyota covered the warranty for this issue "until 10/21/2022 or 150,000 miles, whichever comes first". Therefore, since the date 10/21/2022 already passed, but the car having less than 150,00- miles (91,079 miles), Toyota representative told me Toyota will not cover the repair of this issue. Consequently, I am addressing this issue to NHTSA, with the hope that NHTSA can ask Toyota to cover the repair of this issue, by either making an exception or revise the warranty conditions (I. E. , up to 150,000 miles, without date limit). Thank you.

When I put the car in reverse and then in forward the car jerks. When I'm driving the car at lower speeds and my foot is not on the gas pedal and then I press the gas pedal the car feels like it's going to stall, or shifts down or up jerky like it skips gears or it can't decide what gear it should be in. I understand there is a technical service bulletin to resolve this issue that Toyota is aware of. The bulletin recommends that dealers reprogram the pcm module. The bulletin is TSB #t-sb-0330-17. The dealer won't reprogram because it's nit a recall issue.

Update to NHTSA id - 10937419 my 2016 Toyota Camry se has since been back in and out of the shop with the same since the original complaint my car has been at the dealership 5 times. Each time was simply told "normal operation" or "could not duplicate". . . It is intermittent had received a call from my service advisor that they pulled codes showing the following; p1604 - startability malfunction p2610 - ecm/pcm internal engine off timer performance b1507 - vehicle speed control and idle control related he informed me it was likely a bad ecm and was waiting on Toyota to approve the repair. Shortly after I was informed Toyota denied the repair stating driver error. . . And the service invoice says no codes? I have report showing otherwise!!! in April, my car accelerated pulling into a driveway and ran into the back of truck at approximately 5 mph causing damage to the hood, grill and bumper of my vehicle. I reported this incident and Toyota took my vehicle in for 20 days for an investigation and brought in a "3rd party" to pull the edr box info. When the 3rd party sent me their readings. . . All codes including freeze codes were non-existent? however I demanded the diagnostic report from daytona Toyota and have that to prove they were indeed there to begin with. Where did they go? I spoke with wendy olsen the victim and witness coordinator of the us attorneys office southern district of new york regarding this matter. Honorable william h. Pauley iii us district judge for the southern district of new york arranged a deferred prosecution of fraud charges on Toyota for this same issue in 2014 and upon completion of monitoring for several years the case was to be nullified, however that was changed and was not. . . There must be a reason why!!! I have attached documents to show service records with obvious personal information blocked for privacy reasons!.

This vehicle was purchased used from hertz corp. During the test drive we noticed a hesitation when attempting to accelerate at speeds between 25 and 45 mph. We also drove another 2007 Camry with higher mileage and it did not have the hesitation problem. We asked hertz to have a Toyota dealer check out the problem. The computer was fixed with a software update. The problem still occurred so it was taken to another dealer. Everything was ok. The statement was made by that Toyota service adviser that the computer uses a program to determine the driving habits of each driver and the hesitation problem would self correct. Yeah right. We purchased the lower mileage vehicle, and have driven almost another 5,000 miles, however the problem did not self correct; in fact it appears to have worsened. The vehicle was again taken to a third Toyota service department on March 24, 2008 with the same verbal footwork that its a drive-by-wire system and nothing can be done to correct what I consider to be a potentially dangerous condition. Some day I may need to accelerate hard to avoid an accident or whatever and I would like to have instant acceleration instead of a 1-3 second delay. Considering the high tech systems available to the automotive industry, I find it unconscionable that Toyota cannot fix the problem. Ive reviewed the NHTSA complaints web site, edmonds, and other sites and find this problem is pervasive with other Toyota vehicles. Im requesting that a defects investigation be initiated to analyze and develop a solution to this problem before this throttle/transmission hesitation issue results in injury or death.

The contact owns a 2008 Toyota Camry. The contact purchased the vehicle on February 8, 2008 and immediately noticed an extreme vibration at low or high speeds. While driving 40 mph, the vehicle lunges and constantly vibrates and bounces. The dealer is aware of the failure, but cannot do anything until a service bulletin is issued. The failure mileage was 10 and current mileage was 386.

Transmissions pauses before engaging.

The contact owns a 2007 Toyota Camry. The contact was driving approximately between 40-55 mph on normal road conditions when the accelerator pedal began to stick. There was an application of excessive force to the brake pedal with both feet. The vehicle skidded and loss control and suddenly, the accelerator pedal released. The driver was able to gain control and resume to normal operation. The failure occurred constantly at least three times a week. The vehicle was taken to an authorized dealer on nine separate occasions for the identical failures. There were replacements of the transmission control module (tcm) and transmission. The failures continued which there were no resolutions. The failure mileage was unavailable.

When starting vehicle up from a cold it revs up when you put it in gear it larches fwd you have to apply the brakes hard to stop it then the revving goes down I also get the erratic cruse control when used the sped goes up and down constantly shifting 5-3 overshooting the set speed Toyota says this is the way the manufacture designed the car to operate.

Merging onto the freeway into fast-moving traffic, the car hesitated for several seconds before it downshifted and started to accelerate. On-coming cars had to brake and honked at me. That can be a dangerous situation.

I purchased a 2007 Toyota Camry in September 2006. The vehicle has 16,000+ miles on it. The vehicle hesitates upon acceleration , and at times lunches into gear . This has caused honkning at us and harzardous conditions, especially when changing lanes on the freeway. There is a loud intermitent clunk when turning corners, backing up, and stopping. There is an apparent lack of power when the gears shifts in the automatic transmission. Also, there is vibration when backing up with the air conditioner on. We have had the vehicle in the dealership several times and mostly get a song and dance routine from the dealership. They said that everything we were experiencing was normal or due to the computer design or emission standards. This is very difficult to accept since I have been driving for 50 years and have never encountered anything like this before. Toyota has at this point not been able to resolve any of these issues. However, they did remove and replace the gas tank to eliminate the clunking problem, and I now know according to the dealership that it was not necessary. The clunking is still present. This car reacts like a vehicle with 200,000 miles on it that is in dire. , it needs f a tune up and major overhaul. My wife was involved in a rear end accident 6 weeks ago, and now we realize that this may not have occurred if the car would have accelerated properly.

I purchased a new 2007 Toyota Camry in June 2006. After returning the car to the dealership several times because of the sluggish acceleration from a stop was consistent and the passing gear downshift felt delayed as if there was a communication lag between the tcm and actual switching of the shift solenoids at speeds less than 50 mph. The cruise control will not set speed. On steeper grades and on the interstate the down shifts are very frequent and at times very dramatic. When cresting a steep hill the transmission down shifts at the crest and takes 2 or 3 seconds to release the throttle, picking up anywhere from 10 to 15 mph and I have to break suddenly in order to slow the car down. I was told by Toyota representative that a technical service bulletin came out in September of 2006 for an ecm calibration enhancement to shifting performance and smoothness and this new computer software had to be downloaded in the car and this would recalibrate ecm (pcm) engine & transmission. The catcher to this is that the customer has to request this download before the dealership will follow through. If you don't know about the bulletin how can an average customer request this? the download was performed on this car but didn't help any. The dealership took the car back and I was given a new one in Dec. 2006. Same thing with this one. I have been through national center for dispute settlement with an appointed arbitrator who had the car inspected by an ase independent inspector. He agreed with the above but in conclusion stated that Toyota should "diagnose and repair as necessary". I feel that this is a no win situation for the consumer and Toyota knows all about the problems but just doesn't know how to correct them. Because of the lack of safety the "lemon law" should be put into effect and these cars recalled. Toyota is not going to take responsibility unless forced. This is my first and last Toyota vehicle.

Throttle and transmission hesitation when starting out from stop, and when attempting to increase speed, hazard avoidance, followed by speed overshoot. Cruise control over reacted to slight grade increase, such as an overpass, by down shifting the transmission 1 to 2 gears and accelerating past set speed by 7 to 10 mph. Car will slow to set speed and repeat the down shifting and acceleration until the cruise control was turned off or the road was leveled. During long up hill driving the cruise control has to be turned off completely as it presented a great possibility of causing an accident. The dealer maintaied s that the engine, transmission, and cruise control operated normally.

The Camry 4 cylinder has a major lag in response time associated with low speeds. There is an obvious delay between the gas pedal being pressed and the engine responding. The dealer attributes this to the drive-by-wire throttle system which Toyota has already released a software update regarding the tcm module. They say this is normal.

- the contact states that on 12/9/06 she driving when her vehicle had power surge the weather was clear. She was parking when her vehicle suddenly accelerated and jumped the curb. She contacted the dealership and they are saying that they have no responsibility for occurrence. The contact said that she found several other similar complaints on the internet. The contact believes that the problem is a result of a faulty speed control modulator. The vehicle is currently at a repair shop. The contact also has a copy of a police report.

At 200 miles noticed slippage in transmission. Reported problem to dealer, but was ignored and told that the computerized system needed to get adjusted to the driver. Over a period of time the problem worsened in spit of complaints to the service center. On 11/16/06 the car was finally taken in for repairs (I was told by a customer rep. That there was a valve that was defective and Toyota would replace it. The car was expected on 11/17/06, but due to a problem it was set for delivery on 11/18/06 at 9am. When I went to picked up the car the service director said that they could not fixed the problem, and the transmission would have to be replaced. I was shocked and disappointed at this new development. Toyota arrogance and the dealerships incompetence and impolite response to my initial concerns is inexcusable. The matter at this time is unresolved since I no longer want this car.

The second generation Toyota solara uses "drive by wire" technology instead of a throttle cable. My car experiences a lag between the time when I press the gas pedal and when the car actually starts to move. This happens in a specific scenario where the car is decelerating, but then the driver resumes accelerating. The lag can last up to 2 seconds and presents a critical safety issue which has led to three near miss accidents in intersections for me. This feels like it would if your car stalled in the middle of the intersection and then the light changed. A technical service bulletin was issued for certain VIN solaras which reflashed the ecu to a new program in an effort to reduce the lag. This was not an effective corrective action. Toyota has no solution at this time and this puts my safety at risk. ,.

I brought the car to the service department on 05/16/07, and they reprogrammed the ecm( engine control module). The car seemed to be much better in terms of erratic shifting and acceleration. I would suggest to anyone with a similar problem to have this procedure done.

The contact owns a 2007 Toyota Camry. When the contact applied normal pressure to the accelerator pedal while at a complete stop, the vehicle hesitated and lurched forward. He has taken the vehicle to the dealer on numerous occasions and they repaired the tcm. However, all remedies to date have been insufficient in correcting the failure. The failure mileage was 1,941 and current mileage was 12,878.

This complaint is a new 2007 Toyota Camry le 4 cylinder with automatic transmission. This car will hesitate for a long period of time before accelerating from virtually any speed (behavior not seen when accelerating from dead stop), regardless of how hard the driver presses the gas pedal. Problem occurs when moving at virtually any speed and then quickly pressing and holding the gas pedal down so as to accelerate quickly. This behavior is not like any other car I have ever driven, including a rental 2005 4 cylinder Camry that I drove for a week in the colorado mountains last summer (2005). Safety issue is that car is unpredictable in situations where one must move the car to avoid traffic. Example: rolling forward into a left turn at a green light intersection, press gas to clear the intersection before oncoming traffic gets too close, the car did not increase engine revolutions and took over 1 sec. To drop into lower gear and begin to increase engine revolutions/accelerate. The car's failure to respond to gas pedal input was so long that I would have had an accident if I had persisted in the left hand turn; I had to turn the car parallel to oncoming traffic to avoid hitting the oncoming car. This behavior is repeatable and the delay can be up to 2 sec. In length before the car even begins to accelerate. . Read more...

Throttle response delay in 2007 Toyota Camry (4 cyl. Auto) camry - bought new 4/06 from Toyota of nashua (nh). Defect is a delay of 1 1/2 seconds in throttle response. Delay was most noticeable at normal urban traffic speeds of 35 to 45 mph. A light increase in throttle at constant highway speeds in the 35 to 45 mph range resulted in the engine 1) usually not remaining in high gear 2) having no response for 1 1/2 seconds, and 3) then roughly down-shifting, as if the driver had called for strong acceleration. The car's speed "sagged", and then the car's engine oversped. The driver then had to decrease throttle to prevent overspeed in traffic. Pulling out into traffic becomes unpredictable and dangerous. Delay and/or over-response in the throttle control's action may create skids on wet and icy roads. Less experienced drivers may become un-nerved by this kind of throttle response. Toyota's response to complaints consisted of these replies: (listed in the order in which they were given over multiple service visits) 1. "we know what it is. It is the fly-by-wire control. They all do it and the owner has to live with it" (spoken over the phone prior to the first service visit) 2. "operating as designed". . "this isn't a safety issue". 3. "the Camrys have a driver habit imprint feature which adapts to the driver's style". 4. "the car is pretty much normal". 5. "he has seen a few of these". (garage tech rep. ) during service appointments, the dealership supplied three 4 cylinder, automatic 2007 Camrys as "loaners". None of these cars demonstrated the same drive-train behavior. The writer has been told of two other Camrys which exhibit the problem: hey are serial #s: 4t1be46k27uxxxxxx and 4t1be46k87uxxxxxx a similar complaint is documented on-line in the "car and driver" magazine's user review.

About 2 months ago, I purchased a brand new 2005 Toyota Camry se v6. I have already taken it back to the dealer because of transmission issues. I push on the accelerator and nothing happens. . . Then seconds later (after I've taken my foot off the gas), the engine revs up to 5000+ rpm and stays there for a few seconds. I fear for my safety! the dealer said they had tons of complaints, said this behavior was completely normal, but had two "upgrades" for the car's computer system. They told me the upgrades would fix the problem. . . And it did - for a week. For that week, my brand-new Camry was the greatest! after a week, I noticed it seemed to be slipping back into it's bad habits. Now, a month later, I am taking it back again. It is just as bad as when I took it in the first time. I have been close to getting into at least 3 accidents because of this issue. It is completely unsafe, Toyota knows there is an issue (they have "fixes"), and yet they keep selling their cars. I bought a new car so I wouldn't have these problems! I spent a lot of money, and I feel like I got a lemon. This car needs to be recalled.

There's always a hesitation in transmission.

Recently I brought my 04 Camry to my dealer because of sulfur smell and rattle at light acceleration. The dealer verified the problems and replaced the converter and intake manifold according to the tsbs. They said they also had to re-program the ecm. Then after I picked up the car, I found everything is harder: the acceleration, steering, and braking. I found it is hard to maintain a speed whether on local or highway. On may 28,2005, while I drove the car on highway with 4 persons sitting in the car (including me), I found the steering was very hard and felted like it was locked, and I found it is very hard to accelerate to hwy speed and hard to maintain it. I brought the car to the dealer again on may 31. After having a technician test drove it, they told me it was similar to other Camrys (normal) and wouldn't want to solve my problem. I believe they never tried to reproduce my problem (by having more people sitting in the car). I think this problem is a safty issue so I file complaint with NHTSA. I also feel the car doesn't shift right and engine is noiser after the convert/intake change and re-programming.

The contact owns a 2005 Toyota Camry. While driving in second gear (mph unknown) the transmission would downshift when he accelerated. The dealer reprogrammed the transmission chip however, the failure occurred after driving 6,000 miles. The current mileage was 33,000 and the failure mileage was 6,000.

My wife and I purchased a 2005 Toyota Camry xle v6 5sp auto in Nov 2004. Shortly after taking delivery, we started to notice hesitation in the transmission while trying to accelerate from a stop and after slowing down in traffic. We also felt a delay when attempting to go into passing gear. This delay would last up to a couple of seconds. After the delay was felt, the car would accelerate rapidly. This would cause a jolt to the passengers and driver. It seems as though the transmission is not getting the power demand from the accelerator equipment quickly enough. We have taken it to the dealer twice. The problem seems to be getting worse. The last statement from the service manager was " I drove the car and clearly understand your complaint concerning the hesitation. That is the nature of this new technology. We cannot find anything wrong with the vehicle" the service manager denied they had any other complaints from anyone concerning this problem. That's when I started searching the web. After collecting complaints from several web sites such as this, I confronted the service manager. He stated he was unaware of the complaints and gave me the 1-800-# for Toyota. We have contacted Toyota and got a case #. They claim there are two TSB's associated with the problem. My question is "why doesn't the dealer already have the TSB's" my wife is the primary driver and has complained of two near misses caused from this problem. We will give Toyota this opportunity to correct the problem,but I am not getting a warm and fuzzy feeling concerning a fix. Next step is to get rid of the dangerous vehicle.

Severe hesitation when depressing throttle to full-throttle. When pulling into traffic or when attempting to over take a vehicle engine appears to remain at idle when gas pedal is fully depressed to the floor. No down shifting occurs along with no engine rpm increase. After 2-4 seconds engine then responds. If throttle is gradually depressed to full-throttle there is no symptoms, engine does respond properly. I believe it may be a problem in communication between the throttle position sensor and transmission tcm.

The vehicle's abs and traction control warning lights have been activated and the dealer can not determine the cause. The dealer informed the consumer problem could be with either the abs actuator or the internal ecu leaving an open source code. Consumer is very concerned that the problem can not be diagnosed and is concerned about personal safety if components do not function as expected. Ts.
