Tl* the contact owns a 2011 toyota corolla. While driving approximately 45 MPH, the vehicle began to jerk back and forth while decelerating. The failure recurred constantly and was more noticeable when driving between 40-50 MPH. The vehicle was taken to the dealer for diagnostics where the technician was unable to duplicate the failure. The vehicle was not repaired. The approximate failure mileage was 4,000.
2011 Toyota Corolla transmission complaints
Page 2 of 2: complaints 11 to 18 of 18, newest first, as owners wrote them.
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.
Intermittent deceleration issue: while driving and I take my foot off the gas to slow down, the car maintains the speed and does not decelerate until I put my foot on the brake. Takes few minutes to decelerate from 60 to 40, if you not gonna step on brake car still going with the same speed, and RPM does not drops. So unsafe. Scary to drive!!!!
The engine seems to have a mind of it's own between 40 and 60 MPH. When trying to go at an even speed on a level road the car bucks and kicks, the throttle speeds up on it's own, then slows down. I see variations of about 500 RPM on the tachometer. Sometimes when letting off the throttle pedal at these speeds the car keeps going and doesn't get the message it's supposed to slow down. This is scary, it's almost like the car thinks it's on cruise control when it's not at all.
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.

I purchased the car 4/22/11, two weeks later it began jerking and bucking. I thought it was me so at first I did not say anything. After some time it became a regular occurrence. Then on 2 occasions it accelerated on it's own. Even when I applied the brakes it was not slowing down. Finally it did but I was scared I was not going to be able to stop. I took the car to the dealer and, of course, it did not do it. They checked it and told me all was normal. Two days later the jerking and bucking returned and it drove itself again just the other day. The jerking and bucking occurs between 40 and50 MPH. However, the other day it occurred at 35 and 55. When this happens the tach. Dips and dives and the mpg gauge drops to 99.9 . No warning lights come on. This car scares me !!!!!!!!! I have found other people complaining of the same problem and doing all the same things I am doing including this report but to no avail. Toyota is doing nothing about this problem. I called them to report this on tuesday 7/19/11 they gave me a case # and told me a manager would call me by friday. I received no call.
Immediately after purchase we noticed a transmittion problem where there was a fluxuation of RPM while driving at 40 - 65 MPH. The computer is telling the transmittion to shift for some unknown reason. It can not find a cruse gear to remain at speed.
Intermittent deceleration issue: while driving and I take my foot off the gas to slow down, the car maintains the speed and does not decelerate until I put my foot on the brake, sometimes I have to pump brake to bring speed down. For lack of better description, it feels like the car is on cruise control. I have been back to the toyota dealer three times and after test driving and running diagnostic testing, was told this is 'normal'?
