| Since leasing this brand new 2011 corolla, i noticed that at speeds between 40mph and 60mph the car would feel as if it was decelerating, akin to being buffeted by strong headwinds, although the speed did not reflect it. i drive mostly around a city that has many zones where the speed limit is 40mph, so i was experiencing this phenomenon a lot. by the time i had 250 miles on the car, i knew that it was not just a quirk, and i made an appointment to take the car to the service department at the dealership. the person who booked me in for service said that he had never heard about this issue, but i had done some research and saw that many 2011 corolla owners are complaining of the same problem. i told him to check online. i also complained about appalling mileage - i was averaging less than 20mpg - and he said that he would get their technicians to focus on the two issues. within 30 minutes he was back to say that not only had he found the deceleration issue online, he found it on toyota's own service website, and he told me that the company had issued an official service bulletin. it is not showing that one was issued on this site, but i have seen it, and the dealership were able to reprogram the car's computer (they called it a flash). the conclusion was that the poor gas mileage was being caused by the mistiming, and should be addressed by the software update. if you are experiencing this issue, call your dealership and demand that they find the bulletin on toyota's own site. it's there! my car is now driving much better and the gas mileage is improving...slowly. | |||

| I picked up this new lease car march 8, 2011 & noticed this issue at the end of march with about 50 miles on the odometer; car now has 1000 miles on the odometer.. i noticed that always around 40 mph the engine almost stops as if i were driving standard shift (which i am not) & someone downshifted into another gear, or if the speed control was on (never use it) & it came out of the set speed.. the first time it happened i kind of ignored it but then when it happened again i stopped at the dealer gettel toyota where i picked up this lease car & the person in the service department told me not to worry about it that the vehicle was getting used to my driving habits & that if something were wrong engine/dash lights would go on (pp).. so i went my way keeping his words in mind.. this problem still exists with 1000 miles on the odometer & while i was concerned about it i didn't raise any red flags until now i see i am not the only toyota corolla owner having this issue which leads me to think its another toyota design flaw.. i learned that term design flaw from toyota when i had my 2007 corolla & filed many lemon law complaints on it & toyota would repeat those words in their responses since toyota doesn't participate in lemon law negotiations they told me.. i have been leasing cars since 2002 & this is my second toyota lease which i wasn't going to do again since i had so many problems with my 2007 corolla but i liked the design of the newer model & couldn't beat the deal toyota kept giving me to take another car from them.. now that i am reading about other owners having this same issue of the speed deceleration i am concerned that there may be a design flaw with the transmission or engine mechanics.. although this doesn't happen all of the time it does consistently happen at 40 mph & is quite noticeable since the car almost jerks forward when it occurs.. | |||

| My brand new car (53 miles on it) seems to loose power when you are driving at 40 to 50 mph. i have my foot on the accelerator maintaining the speed and it feels as if someone else is stepping on the brake. you can feel the surge of the power loss .it drops quickly by itself. also when maintaing the speed of 60 to 65 on the freeway i will let off the accelertor and my car maintains that speed as if i had the cruise control on.it drives qiute a distance before ever slowing down. i took it to dealer but they said nothing was wrong. because i know there is a problem!!!!! and if they took it for a drive as they said they did (several times) there is no way they could not have noticed the bogging down of the engine. | |||

| My new 2011 corolla le might have a safety defect in the transmission or fuel system. whether at freeway or local, i can feel the pull-back while driving. accordingly, the rpm was found to be fluctuated between 100-400rpm dropping instantly (1-2s). it happened a lot. subsequently, the dealer service technicians duplicated my concern (sudden pull-back). they even found the pull-back (or rpm drops down suddenly) in cruise control at 60 miles. then they opened the case and got the field technical specialists check this problem. it takes one week and the report said that other vehicles are checked and same things observed. this vehicle was operated as designed and no repair necessary. but the weird thing is that the service manager (he is the only one that has communicated between these specialists and me) they told me that they also think something was wrong (possible software). they offered me a couples of month payment credit (700-1000$). and they told the service manager that they can't fix it and have to have that done in japan. it takes a while. now the service manager recommended me to claim to the toyota customer service and get my money back. but the toyota case manager is bad. he insisted that in toyota's position, nothing was wrong. he declined my request. now, it is still in the processing. but i am afraid that it is hard to get my money back. i also found the same complaint online. please have a check. see the power train: automatic transmission: http://www.arfc.org/complaints/2011/toyota/corolla/ | |||
