2011 Toyota Corolla: adaptive cruise control problems

Filed Jun 7, 2021 · Acceleration, Airbags · GA

I was notified of the air bag recall a year ago but the car dealerships in my area does not have the parts and I need to use my vehicle daily. So I am not sure what to do from here for that but I believe that the appropriate time to remedy this recall has past already and the fact that we have our children riding with us and we are unaware that their life is in danger or because we can not get it fixed is not acceptable. Then on top of that I am having issues like when my 2011 Corolla is sitting idle it will rev up the engine without touching the gas pedal and does this randomly and without warning and also while I am driving around 55 MPH on the interstate or highway sometimes it will dramatically drop and lose about 10- 15 MPH speed for no reason and this happens randomly as well. And this fluctuation happens during cruise control the most so I no longer even use that function. Also both headlights have moisture in them and are so fogged up now that visibility is almost impossible at night now. Also the weather striping around all my windows have dry rotted and broke off and there is practically nothing left of stripping anymore. Then the center dash above the radio just broke and gave out under my phone holder while driving, it broke into about 15 different pieces. I know that my phone or the holder is even close to heavy enough to cause the dash panel to cave in like that. I called to get a price on the dash and it was like $250+ and who can afford that for a piece of plastic. Lastly my driver and passenger seat will get stuck if you try adjusting them and sometimes it will let you move the seat but to do so you have to hop up and down for several minutes and throughout the adjustment to get the seat to move in any direction.

To whom it may concern, we have experienced anomalous behavior in our vehicle that we believe is due to malware. We were referred to report this from the public service announcement: https://www.ic3.gov/media/2016/160317.aspx#fn1 1. Our engine will suddenly accelerate and decelerate without our foot pressing on the accelerator to cause this change. It will also slowly change when cruising at a constant speed, the car will increase speed gradually with very light pressure on it. 2. Our cruise control will reset the speed at various times, we will be going 70 MPH on the interstate and it will gradually slow down without us disabling it with a brake press or switching it off. (my wife does not use the cruise control and cannot verify this.) 3. Our radio will turn on suddenly without pressing the power button. 4. Our radio will eject a cd without us having the radio on. 5. Our air conditioner light will turn on and off intermittently without us turning it off. (I cannot verify this although my wife has observed this behaviour.) 6. Our air conditioner will function intermittently. Sometimes it will operate normally and other times it is completely nonfunctional. Occasionally it will work at lesser levels but is still functional. Respectfully, norman and monique mapes

Whenever I am driving between 15-25 MPH, the vehicle feels like it's dragging with cruise control on.the RPM would randomly surge then drop as the vehicle goes over 25 or under 15mph. Which feels like the transmission programming to switch between gears is having trouble to do so at the correct RPM for a smooth gear change!

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.

Once a month or so when I am at highway speeds the car does not decelerate as normal when I take my foot off the gas pedal. The car tend to stays at the speed it was at until I use the break. It is almost like the cruise control has been turned on without notice (it is never turned on during these cases). This sometimes includes the slight acceleration like some car get when they are going back on cruise control. Luckily I keep a good distance between me and the car ahead of me. I can see this issues causing accidents.

While driving at speeds of 40 MPH and above at any cruise speed without cruise control not on, the vehicle tends to decelerate and accelerate back at the cruise/RPM speed as if the cruise control is on. Many people are have the same issue.

I was driving on the highway in cruise control set to 75mph, while on an incline, either approaching the hill down/up the vehicle begin to violently jerk back and forth (bumper to bumper). I took my vehicle to the dealership on wednesday 06 feb 2013, issue was not resolved and I was accused of wasting their time. Maintenance manager didn't attempt to recreate issue I experienced on an incline, but instead test drove it on a flat surface about 2 miles, the maintenance team checked the fluids and computer.. Stated on maintenance slip that my transmission fluid is discolored and would need to be flushed soon, computer had no error codes. After I was verbally berated by the maintenance manager, I explained that I would install a video camera in my vehicle to record the events I was experiencing, upon asking if I recorded the issue, would they then take action and repair my vehicle, I was laughed at and essentially told that they would find a way to make sure that toyota was not at fault. I was told by another dealership out-of-state, that fluid should not be discolored under 65k miles and that there was an obvious issue. After no further action was taken, I contacted toyota customer care and filed a complaint, upper management at my dealership then offered to do a ride along, on 12 feb 2013.

More noticeable at highway speeds. Take foot off accelerator pedal, car maintains constant speed as if cruise control in engaged (cruise control was not activated). Unable to coast to reduce speed. Have to firmly press brake pedal to disengage. Taken to dealer for service. Toyota servicing dealer advised me that the care was operating properly and that this was a designed safety feature.

At speeds generally above 40 MPH the engine constantly surges. It surges even while on cruise control. The surges are accompanied by a fluctuation of 400 rpms. One one occasion, I was slowing in traffic on the highway while it was surging - I had to apply more pressure on the brakes as at that very moment it was on an increase in RPM's.

Just leased a 2011 toyota corolla. When at a steady cruising speed, anywhere above 35, there is a scary intermittent dragging or resistance, and then surge in speed, along with crazy fluctuation in rpms, that is uncontrollable. In addition, when letting up on the accelerator to prepare to stop, the car locks in on the current speed, even at high speed and going uphill, and does not slow until the brake is firmly applied. It feels like the car is being controlled by a malfunctioning cruise control, except the cruise control is turned off. I a''m scared to drive this car!

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 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.
