I recently purchased a 2011 toyota corolla with 45k miles. For the past month when traveling between 40 and 70 MPH the car looses power. The tachometer will go down 200 to 300 rpms in a matter of a few seconds. It is like the engine is fluttering then after 10 to 30 seconds power returns and the rmps return to the previous setting. This loss of power makes the vehicle dangerous to drive. I started looking at complaints from other owners of the same vehicle-some found the problem to be in the accelerator pedal. I changed the pedal but it did nothing to fix the problem. After more research I discovered that there is a an official service bulletin regarding this problem. The cars computer has to be reprogrammed (flash). I called the toyota website to ask about the proceedure and if toyota paid for this-also no help. I feel that this is a dangerous condition and toyota should pay for this proceedure I am not the only victim. Toyota could not tell me how many other 2011 corollas reported this problem.

I drive quite a bit and normally know my vehicles pretty good. I have recently obtained this 2011 toyota corolla s and it is in great condition overall. I made a trip 2 days after getting the vehicle and immediately noticed a hesitation between 55-65 MPH. The first time it was approximately 11am in the morning at 78f. Driving on a flat well maintained black top road the vehicle does in fact have a constant hesitation that drops approximately 1000-2000 rpms with a noticeable feel in the vehicle. Immediately (3-4 sec) after the hesitation the vehicle recovers back to the original RPM. As long as staying in this speed range (55-65 MPH) the vehicle has the hesitation repeatedly. The second issue that I have noticed on the same vehicle is the actual deceleration when removing my foot from accelerator. When traveling on the same road and time as stated above the vehicle seems to really coast right along or so it seems. When saying this, I removed my foot from accelerator and the vehicle rolls right along as if I am still pushing the accelerator at which time I must apply the brake more significantly than letting it just coast. I would like to know how this is effecting my gas mileage, is it going to cause undue strain on the drivetrain, is this going to be a problematic issue that toyota is going to continue to ignore?

On 2/19/15 at around 9:27 pm my car was hit by a pickup truck in downtown bellevue, here is what happened 1. I approached the intersection to take a left from bellevue way ne to enter ne 7th st which takes into the lincoln square cinema parking lot 2. I saw the red signal (exclusive left arrow) and waited for the light to turn green to take left. My car was first in line waiting on red 3. Once the left arrow turned green I started turning left and half way into the roadway a pickup truck (driving at around 45-50 MPH) hit my car on the front passenger side (side collision) 4. With that impact my car was dragged about 15 feet and hit another car, that was standstill and waiting to turn right from ne 7thst to bellevue way ne) the impact to my car was so intense police officer filed a case and interviewed witnesses at the scene and concluded it was other guy (pickup truck) mistake. However, I am surprised why air bags didn't deploy? Mine is fairly new car, only 3 year old with 33k milage. I brought it brand new in december 2011 I am taking this serious because, fortunately my wife is not in the car when accident happened. However, me and my wife usually go everywhere together, and I can't even imagine what might have happened if she was sitting in the front passenger sear. So I want to file a case against the car company for selling me a defective car.

When I take my foot off the accelerator, it feels like I have the cruise control. The car decelerate very slowly for anywhere between .5 to 1 mile then the RPM drops suddenly as it should when you first take your foot of the pedal. The other related problem is that if I'm just trying to maintain a constant speed anywhere between 50 and 60 miles/hr it feels like the engine stalls for a very brief moment then shortly after comes back to the original RPM. When I drive car down hill try to apply break to maintain the speed of the car acceleration increases suddenly 3 to 4 thousand RPM and after 3 to 4 seconds cars come to normal engine RPM both problems describe above are easily reproducible and my local toyota dealer said its normal. Its very scary to drive this car and since 3 years I was complaining to local dealer and get same answer every time its normal. Please do some thing about this.

I purchased this car as a new vehicle. Ever since I have had it there has always been an acceleration issue to where it does not slow down for several seconds after releasing your foot from the gas. It accelerates often to where you have to apply the brakes firmly to where the anti lock then kicks in. During servicing it has been brought to the attention of the dealership but they have continued to say that there is not an issue. I have had other family members operate my vehicle to verify that this issue is in fact an issue and they experienced the same situation. This is very dangerous and will end up costing someone their life due to the manufacturers dragging their feet on addressing the issue.
