Failure Date: 01/13/2011

My 2010 Tacoma, while sitting at a stop light, suddenly surges as if somebody hit the gas or slammed me in the rear. It hasnt pushed me beyond my brakes but it is very disturbing. I reported this to the Toyota dealer and they said they couldnt reproduce it. It doesnt happen with any regularity, it just happens out of the blue. Additionally, when you go to very low speeds and make a sharp turn the rpms jump to about 3,000 and then it feels like the transmission kicks in. This was also reported to the dealer who said it was by design but if it is it is poor design.

The contact owns a 2006 Toyota Tacoma. The contact stated the vehicle has had problems with the cruise control. The failure began after the contact had the transmission serviced and the transmission was not refilled properly. After the service, the contact stated that the cruise control started to accelerate pass the speed that it was set with being reset by the driver. The vehicle was taken to the dealer again and repairs were made to the electronic control unit, which has caused the rpms to idle either excessively low or excessively high. The contact stated the vehicle will also downshift from fifth gear to second gear when driving with the cruise control set to 55 mph and above. The failure mileage was 85,118 and the current mileage was 85,557.

On June 11,2010 I was changing the anti freeze in my 2003 Toyota Tacoma. The vehicle was in park and running to warm engine to open thermostat to get more coolant from the lower block . Well I decide to boost the engine speed by manually moving the throttle . To my surprise my truck lurched back before coming to a stop I check the shifter it was still in park . But a further exam the vehicle stuck in reverse and will not go into any forward gear. I m' going to check to see if the linkage needs adjustment everybody I talk with said it was not suppose to move unless the brake was applied first.

2005 Toyota Tacoma lunges or surges while holding the brake at light. If I don't hold the brake firm it could rear end vehicle in front of me. Dealer says its normal. And charged me to inspect. Airbag light came on dealer told me it was a part in the airbag and wanted 612. 00 to replace stating that it may go off while driving. Causing a crash . Shouldn't a part this critical be covered for life of truck?.

'09 Toyota Tacoma. Transmission shifts erratically at slower speeds. Drops into first gear and lurches when turning a corner. Truck transmission feels out of control at apex of turn in an intersection. Not safe for foot traffic or other vehicles in the intersection. Dealership says transmission is ok. Many other complaints about this problem on edmonds. Com forum. Toyota will not acknowledge the problem.

2010 Toyota Tacoma double cab pre-runner, I have experience a sudden jerk (like other car has hit me on the rear) while I was stopped and the brake was pressed while waiting at the traffic light. It happened to me three time for five days after I brought my truck to the dealership to repair this problem, which they said that there is no problem and it is just because the Tacoma has a sequential type of transmission. .

The vehicle surges unexpectedly. One or more times a day, depending on travel needs, I experience surges both at complete stops and when accelerating. Depressing the accelerator pedal from a stop or roll includes a "delay" in response from the vehicle, then the unexpected surge is noticed. Generally, a small amount of pressure on the pedal does not yield a desired acceleration effect, instead a "wait and go" effect is experienced. Several times, this delay has caused near misses in terms of accidents. Expecting the vehicle to respond to accelerator pressure but not getting acceleration is considered hazardous. Surging forward violently when at a complete stop is another concern. With the brakes completely depressed, the vehicle will surge forward at most traffic lights or during stop and go traffic. This vehicle was brought to the dealer a week after purchase with my concerning of shifting and sometime erratic behavior. The dealership did little more than take a short test drive with me (no diagnostics, no formal or mechanical evaluation), and tell me nothing was wrong with the truck. The truck had less than 1000 miles on it, now with 2600 miles, the problems persist.

Truck was purchased new in may 2009 (tacoma sr5, 4x4, access cab, 4l, v6, automatic transmission, towing package). When coming to a stop, the engine will rev up to 5000 rpm. My foot is on the brake when this happens, and I am not slamming on the brake. When I shift into neutral, the revving stops. This has happened three times in two days, not every time I stop. The truck has 3900 miles on it. After the third time, I drove directly to the dealer. They did a "system health check" and the test came back ok. They could not duplicate the condition in the time they had the vehicle. I left the vehicle there for a technician to drive to see if he/she can replicate the condition.

I previously filed odi complaint 10282779 to report to two instances where my Tacoma accelerated on its own at a time when I had about 17,000 mi. On the vehicle. Thereafter I tried to troubleshoot the problem. The only thing that changed prior to the onset of the spontaneous acceleration was that I acquired a blackberry curve to replace my previous cell phone. My old cell phone was smaller, so while driving I usually kept it in the slot next to my gear shifter. My blackberry was much bigger and didn't fit in the slot. Therefore I put it in the cup holder underneath my dashboard. It was then that I started experiencing the acceleration problem. Subsequently, I started carrying my blackberry either in my backpack on the passenger seat or in the slot where I used to keep my smaller cell phone and I no longer charge the blackberry using the charger that plugs into my lighter socket in my dashboard. With one exception (which I shall describe) this has solved the problem over the 9,000 mi. Since it began. On 10/21/2009, I was driving my Tacoma at a time when I needed to charge my blackberry. I plugged my blackberry into the car charger and placed the blackberry in my backpack on the passenger seat. Within 10 miles my Tacoma started accelerating uncontrollably. I shifted the truck into a lower gear and unplugged my phone from the charger, but the vehicle kept accelerating. I shifted to neutral and turned off the engine when it started to redline, and steered the vehicle off the side of the road. After I stopped, I shifted into park and turned the ignition and the engine again started to redline. I let it rest a couple of minutes, and it started normally and I drove off. I no longer charge my blackberry with the lighter charger and have not had any subsequent problems. It is my belief that my blackberry's electromagnetic frequencies interfere with my Tacoma's electrical system when the phone is either too near the dash or plugged into the car charger.

The problem with the transmission is when I slow down to go around a curve or decelerate for any reason it does a hard down shift and then when I proceed to press the accelerator the truck acts like it is searching for what gear it should be in, at the same time the rpm is increasing (engine starts to race) and finally the transmission lurches forward and goes into gear. If you are in heavy traffic or crossing a busy highway this is very unnerving and in my opinion a safety issue and an accident just waiting to happen. I have taken my truck to the dealer twice and was told that there was nothing wrong with it. I was told that it was new technology and that I had to get used to it.

I purchased a new Toyota Tacoma sr5 pickup 8/27/09. Immediately I noticed a problem when I slowed down at speed bumps and to turn corners and then started to accelerate. The vehicle would hesitate then surge forward. I can stop the hesitation somewhat by very lightly pressing the accelerator after I slow down and then slowly accelerating. If I forget to very lightly accelerate, the vehicle will surge forward following the hesitation. One time this surge as I turned a corner almost took me into oncoming traffic. I attempted to resolve the issue with service representatives locally who told me the transmission was operating normally. I filed a complaint with Toyota, was given a case number and was told by their complaint center that it was Toyota's position that the transmission is operating normally. I feel that this tendency, which has been documented by numerous other owners at online sites such as edmunds. Com, is a safety hazard that should be remedied in a recall. This situation occurs every time the vehicle is driven and requires very careful concentration to avoid a sudden and potentially unsafe surge in speed. Nothing has been done to correct this issue and no response other than to deny my complaint has been taken.

My 2008 Toyota Tacoma accelerates on its own without warning when driving normal speeds. This happened twice in the last week. Both times the accelerator pedal was not blocked or impeded. When I subsequently shifted to neutral, the first time the engine returned to normal, the second time the engine raced to redline so I turned off the ignition. Thereafter, I started the engine and it raced to redline, so I shut it down. The second time I started it, the engine returned to normal. The first time the problem happened, I think that had been using cruise control earlier in the 45 minute drive. The second time, cruise control had never been turned on or engaged and the problem occurred in the first 2/10 of a mile into my drive. The pedal did not get stuck after I had pressed it all the way down. In both cases, I was driving a constant 35-45 mph when the truck took off on me. When I say it accelerated, I mean pedal to the metal acceleration - not gradual like when cruise control resumes. I took the car to the Toyota dealership for repair. They tested it and drove it 80 miles, but they couldn't find anything wrong or anything that could be fixed under warranty. I called Toyota's national office, and they said that if the dealer didn't find anything wrong, then there was nothing they could do. I would have thought they would have shown serious concern for this dangerous product defect.

I drive a 2009 Toyota Tacoma. The transmission hesitates/sticks when the driver accelerates after DE-accelerating. This occurs when the truck slows to a speed below 15-20 mph, especially when turning a corner or yielding. The driver is pushing the accelerator, trying to get out of harms way of other traffic and the transmission is sticking and revving up; not wanting to kick in and go. Toyota claims this is normal. This is not normal - it is a safety hazard.

Note: the date given is for the first of several incidents. Vehicle: 2009 Toyota Tacoma; 4 cyl. Auto trans. When ascending mountain passes, in drive, letting off on gas as summit is reached, vehicle accelerates over summit and continues acceleration. I've been able to drop the rpm by repeatedly hitting brake and then tapping gas. This lowers the rpm and puts transmission back into highest gear. This is a computer or electronic problem. It has happened the same way several times, over a few thousand miles and several months. I now make the ascent in third, shifting into drive at the summit, with no problems. I took the vehicle to the dealer, lithia Toyota in klamath falls or, and was told "the computer needs to adjust to your driving style", but it still hasn't happened. Toyota is stonewalling, and telling the dealers to do the same. There are dozens of similar complaints about Tacomas with automatic transmission.

The transmission in 2009 Tacoma 4wd v6 does not shift down smoothly as the truck slows down into a turn and begins to accelerate out of a turn or in a straight away. The issue is pronounced in speeds of 35 mph and less . There seem to be a delay in response when accelerating,. Until the transmission responds and the truck lurks forward . I checked with the Toyota dealer , and the dealer does not think there is a problem . I checked Toyota forums and found out numerous complaints about the same issue that I have . There is for sure a problem with the transmission or the software. My truck has only 2700 miles on it . All the complaints I read regarding this issue are low mileage trucks and it seems to be affecting the 2009 model.

2009 Toyota Tacoma,5 speed automatic transmission. When slowing to make a turn and then resuming speed, the automatic transmission seems to be in neutral or severely slipping. Toyota service states this is normal ! makes turning with oncoming traffic is very hazardous as you don't know if the transmission will be properly engaged in gear. Always happens at 20 mph or less when in drive. I have also had this same problem when in local stop and go traffic, no turning involved.

I purchased a 2009 Tacoma double cab sr5 4x4 auto in June of 2009. It now has 9000kms. Ever since new I have noticed that the transmission shifts strangely and somewhat unpredictably. When I am driving at approx 18km/h and press the accelerator (to accelerate or continue same speed) the truck usually drops into 1st gear and stays there for a few seconds before going back into second gear. This causes a "lurching" as it should not be jumping to 1st. It is very noticeable and I have driven many, many automatics, including Toyotas, and they do not do this. I had a 2001 Tacoma before purchasing this new one and it did not do this. Also, when you shift the truck from neutral to drive, and immediately press the gas, it is almost like the truck hesitates, then lurches forward violently. Sometimes causing wheelspin. It seems like when shifting to drive there is no power for about 3 seconds then it suddenly hits. These problems are dangerous as they cause the vehicle to lurch forward when in traffic this is not safe.

2009 Toyota Tacoma 4x4 crew pickup truck with auto transmission and v6 engine accelerated unexpectedly to over 80 mph, then later on the same trip it happened again. I was on a long straight stretch of interstate the second time so I allowed the truck to accelerate to approximately 95 mph at which time I stopped the truck again. The first time it happened, I had disengaged the cruise control due to a slower car in front of me and when I engaged the cruise control resume feature the truck accelerated 15 mph past the preset speed at which time I turned off the cruise control and regained control of the truck. The second time that it happened the truck was again in cruise control mode and was going up a long hill. When the cruise control shifted the transmission down and accelerated to maintain set speed the truck continued to accelerate past 95 mph and was only stopped by turning off the cruise control again. I allowed the truck to get to that speed to see if it would discontinue accelerating but chickened out at 95 mph because it is after all a truck. I took the truck to the selling dealer, he tried to make it happen again with no success (told me he would have to replace the cruise control unit but could not do that unless he could duplicate the problem because it is a very expensive change out) and it has not happened but one more time. 4 things seem to be common: 1. The cruise is turned on. 2. The vehicle is accelerating when the problem starts. 3. The transmission has automatically downshifted. 4. The problem is halted by turning off the cruise control. I had the dealer document the problem since he would not fix it. I hope this info helps in your continuing investigation of the problems that Toyota seems to be having. I am not a disgruntled customer, I have purchased a 2010 corolla from the same dealer since the incidents.

Failure Date: 07/12/2009

I own a 2006 Toyota Tacoma prerunner double cab 4x2 v6. I bought the truck new from the dealership and have experienced four instances where after pressing the gas pedal hard, thus into overdrive, the truck either kept speeding up or did not rev back down. 1st instance - about 6 months after buying the vehicle, I was entering the freeway and needed to speed up to enter into traffic at speed. I pressed the gas pedal hard enough to boost speed. As I entered traffic, the truck just kept speeding up. After applying a light brake, I pumped the gas pedal several times and it the transmission finally engaged and geared back down. 2nd instance - while leaving the freeway @ 65 mph I slowed to 45 mph and switched lanes to the right. Then I applied gas to speed up to merge and the truck did not slow down. Again the link between the throttle and the transmission did not seem to reaction as in a normal situation. I had to merge back because the would not slow down fast enough. After 4-5 seconds the truck slowed down. 3rd instance - again entering the freeway. I applied pressure to the gas pedal to speed up enough to enter the traffic. This time the throttle opened full bore. I put the truck in neutral, lightly applied the brake, and pumped the gas pedal. After 5 seconds the truck finally revved back down. I reached a speed of over 90 mph in this instance. 4th instance - driving uphill the car automatically increased throttle with a small amount of additional pressure to the pedal, the truck surged forward, again full bore. I used the same technique and it eventually slowed. This problem is definitely not a floor mat problem. I now drive my truck very gingerly so as not to replicate the issue. I have taken the truck to two dealerships, both have not been helpful or have recognized the problem. Saying that "your truck is not on the recall list we see here, call this Toyota number. " I know that others with the same model have this problem.

While in cruise at 70mph on interstate highway,vehicle shifts down from drive to second. Thus redlining the engine. Brought this to the attention of Toyota and their answer was,"vehicle is operating properly and is doing what it is designed to do". So they are telling me that they have designed a vehicle that is designed to shift down to second, not third at 70mph.

I purchased a new 2009 Toyota Tacoma in may of 2009. Shortly after purchasing the vehicle I noticed that the transmission 'slips' and does not engage at low speeds after slowing to around 10 mph and then accelerating without coming to a complete stop. This is very dangerous and I have had some close calls when turning left at traffic lights. This is a dangerous defect. I have carried the vehicle to the dealer twice and they say that Toyota has recognized the problem and is working on a computer 'patch' to solve the problem. I was given no time frame to fix the problem. I "googled" Toyota transmission problems and the problem appears to be so prevalent that there is a private web site devoted to this problem. I am wondering why the government has not issued a recall? this is a dangerous situation.
