The cruise control system is designed so the engine and transmission down shifts when the system is engaged and going down hills. This puts much more wear and tear on both the engine and transmission. In addition to the down shift the rpm goes to over 4000 in an attempt to slow the car. This is completely unnecessary and drastically reduces gas mileage, which is exactly opposite of the original intent of the cruise control which was better gas mileage and peace of mind to not speed. The speed does go up 5 miles per hour when this happens. Bottom line is the engineers and their bosses who approved this system are all idiots and should be fired. You would assume you would get better gas mileage when going down hill when the engine would disengage because you would need less power and not more to maintain a certain speed. I was informed by the dealer the cruise control is designed to operate by gearing down, I told him no manufacture is that stupid. He then proved me wrong by showing me the manual proving Toyota is that stupid. I would have never purchased this car had I known this feature was designed in this way. Who knows what other systems in this Corolla are designed in such a stupid manner. I will certainly never buy another auto from this company.
Adaptive cruise control causes the car to down-shift unnecessarily on a straight downhill grade and sometimes increases the speed by as much as 8-10 mph. I feel out of control, which is dangerous. A Toyota technician has confirmed the same behavior on another 2017 Corolla. On one occasion, on a freeway downhill where the speed could have easily been controlled by letting off the gas, the car downshifted to d3, revs went to about 4000, and the speed increased to 70mph - when it was set to about 62. On another occasion, on a relatively flat, straight freeway road, it again downshifted for no apparent reason, and the speed again increased over the set speed (of course the revs were higher again). In both of the above cases, there was no car or other obstacle in front of me that should cause the car to slow down. I've seen the adaptive cruise respond to a car too close so know how that feels.

The cruise control is just awful and has been since I bought the car brand new in December 2016. Just as several others have described, it cannot control the speed when going down hill. It raises the rpm's trying to slow the car down, but it isn't very effective. I've never had another car or another Toyota have such poor speed control. So much, that I don't even bother trying to use it anymore. A cop isn't going to listen to "my cruise control wasn't working right" if I get pulled over. The brakes already feel like they are wearing out at 26k miles. My 13 camry had 30k and the brakes still felt brand new. Same with the 15 sentra I had. The suspension feels rougher and is starting to make noises already. This car shouldn't feel like it has 60k miles on it already.
The vehicle does this 100% of the time. When on the adaptive cruise control on the interstate there are occasions where the cruise will go 14 mph above the set limit and the engine is at 4000 rpm or higher. I typically drive at 65 mph on the interstate; this is causing me to go to over 75 mph while the system is trying to recover back to 65mph. I also own a 2017 Toyota rav4 and drive the same roads; the cruise is 'rock steady'. It holds at a constant 65mph.
I just purchased a 2017 Corolla xse in Feb 2017. The first time it happened I had the cruise control on and was traveling to work at 05:15, and I came to an overpass and on the way down the normal overpass over a cross street, I heard the engine rev and I looked at the tach, and it was at 5000 rpm. I was startled. The same thing happened at the next overpass. This time it was 4000 rpm almost at the bottom of this rather short average downhill. This is still happening, but occasionally it does not. How could this possibly be correct. I can control the speed quite nicely with my foot on the accelerator without hardly any variation of my rpm's. This just doesn't make sense. I am not talking about a long downhill road that has a lane for trucks on the right, where they would have to downshift to maintain a safe speed, this is just overpasses on a freeway system. I asked my salesman, and he said that it was probably normal, and I said how could it be normal for this thing to rev at 5000 rpm on a houston freeway? I only have 5000 miles on this car. This will definitely affect the mileage. I am beside myself at this point.
Cruise control active, I made a speed change using the steering column lever when the engine went to 6,000 rpm in full acceleration. My speed was about 65 on a rural road prior to this event. I tapped the accelerator with no change, then the brake which cancelled the uncommanded acceleration.

While using cruise control on fairly level roadway, (rural road) at a speed of 45 mph, the rpm were about 1500, but increased suddenly to about 4500 rpm. After awhile the rpm would drop back down to normal for the speed situation. This occurs also at highway speed of 60 mph in our area. This occurrence has happened many times. Have returned to dealer twice now. Problem was observed by service manager and local Toyota rep who was in town for local auto show. Car was analyzed and data send to engineer in California who later said car is behaving normal. I found that hard to believe as both loaner cars (2017 Corolla) did not behave in this dangerous fashion. I feel this quick brush off by the engineer (tanaka) who is only observing data and not having to drive this car is wrong. I feel the computer should be adjusted for the cvt to solve this problem. Wife does not feel safe driving this vehicle. We have taken 3 videos to document this event.
When the cruise control is engaged and the vehicle is on a decline the cruise control does not maintain the set speed. Depending on the severity of the decline the speed will increase from 5 to 15 mph. When using the accelerator pedal and maintaining the exact same pressure the vehicle only increases speed minimally (2 to 3 mph) on the decline. When in cruise control the speed increase is very drastic. The Toyota dealership has stated that this is a normal occurrence and that they have tested several same model and year Toyota vehicles and all have the same speeding tendencies so this is normal. The dealership stated that the fix is to engage the manual transmission mode to use the engine compression to slow the vehicle down. I have followed there advice and this does not rectify the problem. The cruise control in all vehicles I have owned is used to maintain a consistent speed no matter the terrain being traversed. This issue has occurred every time we have engaged the cruise control on the vehicle while driving on a highway that has a decline.
When I was driving at night with headlights on, with cruise control on, the car accelerated by itself upto the speed of 85 mph even though I set cruise at 65 mph. I tried this multiple times and all the time it went up to 85 mph and stayed there even though I set it for lower speed. This seems to be happening while the headlights are on. I have drove with cruise on, in the daytime and it works fine. Since then, I have never drove this with cruise on at night.

The high beams on the headlights come on without the control being touched. This began when I first bought the car & still does. At first it would happen at any time of the day but now it happens only when it is dark or getting dark. This could impair the vision of the driver of an oncoming vehicle. It is most dangerous on narrow streets. There are other electrical problems that occur from time to time such as the cruise control, power mirrors, air conditioner, driving & dash lights not working. Also the dome light has remained on causing the battery to run down . These latter problems do not seem to pose the threat that the headlights do but they seem to be connected & they are a distraction that could cause problems. I have taken my car to the dealer many times but they never corrected the problem.

While driving west on highway 50 at 65 mph at approximately 7 pm, I turned off the cruise control and the motor stopped at the same time. The car immediately began to slow down and I attempted to restart the motor, which was impossible with the car in gear (automatic transmission). The emergency lights were then turned on as the cars behind were honking their horns and other cars were passing right and left. We were in the second lane with the headlights, also on, of course. I tried starting the car in neutral and that didn't work. When we came to a full stop, I put the car in park and started the car. Everything went well after that.

On a trip to south carolina from new jersey interstate driving I experienced an issue with the cruise control. Issue is : when I come up on slower traffic and hit the brake the cruise control disengages as it should but when I let up off the brake pedal the vehicle accelerates rapidly on it's on without hitting the resume lever. Thinking quick I turned the cruise off. This happened 6 times on the round trip I finally quit using the cruise. The Toyota dealer said there is no recall or anything for this issue. I'm telling you this is unsafe as hell! I have an extensive mechanical background, I don't care what anybody says! I know what happened my wife and daughter saw it happen to.

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 petal. 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 on route 30 east in PA, I experienced a scenario where I was on cruise control and pressed the brake. The car continued to accelerate at it's speed and subsequent pressings of the brakes did not slow the car. I shifted the car into neutral and the brakes still were not slowing the car enough. I had to drive into the left shoulder and grass beyond that in order to slow the car down enough to let other cars pass so I could go into the right lane. The next business I took my car to the dealer and after driving 7 miles and looking for error codes, reported that they "could not reproduce the issue". My car already had all the fixes for the unintended acceleration issue that Toyota had a number of recalls for done in December 2013. This issue needs to be further investigated by Toyota because if the reported fixes do not work, then there could be a significant number of accidents/fatalities yet to come. I never had experienced this issue before.
The contact owns a 2009 Toyota Corolla. The contact stated that the cruise control failed to work. The dealer diagnosed that the spiral cable assembly needed to be replaced due to the cable not being connected. The vehicle was taken to an independent mechanic who replaced the spiral cable assembly. The contact was later notified of NHTSA campaign number: 14v168000 (steering). The vehicle was repaired. The approximate failure mileage was 100,000.
I was on the highway going about 70mph. My exit was coming up on the right side so I put my foot on the brake to slow down. However the brake stuck and the vehicle wouldn't slow down, it kept going. I had the cruise control on, and usually if I brake without first turning it off it slows down, but that didn't happen. So I turned the cruise control off but nothing happened. My car kept going. I pushed down on the brake, but that made the car accelerate even more. I checked to make sure the pedal wasn't stuck, it wasn't, but I knew that wasn't the problem because my car was accelerating when I was hitting the brake. Luckily there was no one in front of me because I was going over 110mph. I sped at this speed for quite a ways maybe 3/4 of a mile. I thought I was going to die and had my phone in my had to call 911. I kept pushing on the brake since I didn't know what else to do (this of course made me go faster and faster). The brake wouldn't go down though. I didn't understand what was happening. It was like stuck? finally I heard my accelerate pop. And the car started to decelerate.
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.
Cruise control engaged while off. I typically use cruise control every day. When I attempted to use it on 7/27, the indicator light showed "on" but it would not engage when I tried to set the vehicle speed. I turned the cruise off and retried - again the control failed to engage. After 4 attempts I gave up and left the control off. A few minutes later the car accelerated on its own (on a slight uphill incline), hard enough to drop from 4th to 2nd gear, as if the cruise control engaged. I hit the brakes and the acceleration stopped. Operation then seemed normal. After a few minutes of thought, I decided to (cautiously) check the cruise control again. It engaged and operated properly. After checking though, I turned it off. Later that day I took the car to a Toyota dealership. The service department scanned the electronics, but found no errors.

The contact owns a 2008 Toyota Corolla. The contact stated that while attempting to activate the cruise control, the cruise control button and arm separated from the base due to defective material. The vehicle was taken to dealer, where the cruise control switch and arm were replaced. The manufacture took a complaint and offered to reimburse the repair cost. The failure and current mileages were 39,436. Sm.
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 rpm¿¿s, 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 no¿¿t 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!.
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 break 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.
The contact owns a 2004 Toyota Corolla. The contact was driving with the cruise control set to approximately 70 mph. When the brakes were applied to disable the cruise control, the vehicle would not respond and instead, accelerated abnormally. The brake pedal fell into the floorboard and the contact applied the emergency parking brake but the vehicle still would not respond and the contact crashed into the rear of a vehicle. The vehicle was towed to a dealer and the manufacturer was made aware of the failure. The manufacturer had an engineer inspect the vehicle who was unable to duplicate the failure. The vehicle was not repaired. The approximate failure mileage was 66,771.

2011 Toyota Corolla maintains the speed/rpm when the foot is off the accelerator pedal. It happens at all speed, but it mostly visible at 60mph and above. The car will maintain the speed, as if the cruise control was engaged! when going downhill, even braking is not enough and I had to resolt to placing automatic transmission into neutral, in order to drop the speed. Lawrence Toyota (NJ) technician/mechanic test drove my car and confirmed that vehicle was not operating normally. Yet, after they (dealership) contacted Toyota support in California, I was told that vehicle operates normally?! Toyota refuses to take responsibility and fix/recall 2011 Corolla's. This is a big safety issue. Someone will crash their car and possibly die because the car won't decelerate, when foot is of the accelerator pedal. Here is a link to a forum where owners of 2011 Toyota Corolla describe exactly the same safety issue with the car. . Read more...
Letter from congressman on behalf of constituent re sudden uncontrolled acceleration of a Toyota Corolla automobile dot/I#2011-2068. The consumer stated she was traveling at the posted speed limit, when the sign ahead indicated to reduce speed ahead. The consumer reduced her speed to the posted limit by pressing down on the brake. As she attempted to brake, the vehicle continued to increase in speed and a loud noise was present. The consumer stated she continued to press harder on the brake and she could feel the abs activating. The abs sounded like a high pitched noise and pulsating very fast. The consumer finally came to a complete stop, before going through an intersection. However, the engine was emitting a loud roaring sound. The consumer shifted the gear from drive 1 to drive 2 and the vehicle shuddered. She tried to shift to park, but as she got to reverse the vehicle tried to buck, so she put the gear in neutral and turned off the vehicle. The consumer stated her cruise control wa activated at the time of the incident. However, the dealer stated the problem had nothing to do with the cruise control.

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?.
