general problems of the 2017 Toyota Corolla

Recently purchased a used 2017 Toyota Corolla. During the test drive I did not attempt to use the cruise control as it was only driven on city or small highways. Travel with the car at those locations has been good. Yesterday while on a freeway, I used the cruise control. It started out okay, but when I got to a downhill or uphill location, the car engine got very loud. The rpm’s revved to an extremely high level and the car accelerated and kept accelerating beyond the cruise set speed. I became very scared and didn’t know what was happening. Luckily I had quick thinking to hit the brakes immediately. I actually pulled over and stopped due to the issue and my nerves. The engine looked okay so once calmed, I began traveling again. I wanted to use the cruise on the freeway, so attempted a second time later. The same exact thing happened in the uphill / downhill scenario. I realized there is something wrong and it is not a good issue at all! this morning I began researching things related to the car. Prior to my purchase, I had checked for any outstanding recalls (which there were none) and problems people may have had with this car. There were no general concerning things I saw. This morning I began searches specific to cruise control issues and found discussions and even videos pertaining to cruise problems. People mention an array of scenarios and possible reasons such as the brake pedal sensor not working. Then I came across this site where other people described the same exact problem and safety concern of mine. I agree with all of them that it is definitely scary and thank goodness the brake works otherwise it would be a major safety concern!! I am now concerned and wondering why after many people have problems with this, there is not a fix or something being done?.

Vehicle went out of control in regards of speed when traveling downhill with cruise control on. Vehicle began heavily decelerating and accelerating along with high engine rpm. This is extremely dangerous and I am unable to use cruise control because of it.

While coming out of a revered position, I was driving forward and my brakes vibrated. This caused my car to stall while in the driving position.

Red brake light, abs, vsc, power steering, and mil lights came on. Dtc's u0129.

Bought the car last April, it has given me no problems, until now. The car start to loose acceleration when driving almost got into two car accident on the road, called Toyota but they want to charge me to inspect the car, the car seems to be stuck on gears like if it was on neatrual.

Was driving in middle lane of interstate 10 when vehicle lost power. Car would not accelerate. Car coasted for approx. 5 minutes. Had to put on emergency flasher, put car in park to restart engine. Cars coming up behind me doing 75/80/85 miles per hour and had to swerve immediately to keep from hitting my vehicle. I had a friend in passenger seat and we were both scared for our lives. To this day, I am afraid to drive on interstate or any other busy highway because Toyota said they could not find any problem.

My car was struck by a car spinning out of control mainly the drivers side door center post and rear door. I think the car is totaled. The passenger rear wheel is bent from the impact. None of the air bags deployed. The police officers that worked the accident was astonished. He said they should have deployed. My car was moving about 15mph the car that hit mine was spinning very fast. The roads were slick and it was raining. The impact was about 40 to 60mph at least.

Car speeds up at stop or low speeds on highway and streets stop and go traffic.

On interstate in western maryland and west virginia, road curves to left, going uphill (steep) at 70 mph and 4000+ rpm in drive, 3 lanes, truck in "slow" right lane (40mph), Corolla in middle lane, left lane empty. Safet sense "sees" truck and hits brakes. No one behind, thanks. Possible rear end collusion. Serious safety fault. Difficult for Corolla to regain speed. Does not happen on right curve as those vehicles in left lane are moving faster than Corolla.

The vehicle was traveling in the left lane of a divided 4 lane highway at a speed of 55 mph with the speed control and radar engaged. The road curved slightly to the right. The vehicle approached a car stopped in the left turn lane in the median - not it the lane of travel. Due to the curvature of the road, the radar detected the stopped vehicle and apparently believed it to be in the path of travel. The radar/speed control sounded its "collision alarm" and rapidly decelerated approximately 10 - 15 mph before I could disengage it and regain control. Had there been a vehicle following me this could have resulted in a collision as a following driver would have seen that the lane of travel was clear and would have no reason to expect my vehicle to suddenly decelerate. I have experienced similar issues when a vehicle in front of me turns right or left at an intersection. I can see that the vehicle is turning and I know how long it will take to clear the travel lane. The radar speed control system seems to detect the slowing vehicle but takes a long time to process what is happening. The speed control will abruptly decelerate the vehicle after the turning vehicle is well out of the intersection. Again, the sudden deceleration without apparent traffic conditions to warrent such action are a hazard to the vehicle and any following vehicles. I took the vehicle to the service department at at Toyota of goldsboro (nc) on October 23, 2017. Their opinion was that the speed control/radar was "operating as designed. ".

Speed control engaged going downhill on highway at 60 mph - car accelerates very quickly to over 70 mph and the tac goes to 4500. To disengage I either turnoff speed control or brake. This happened four times today. I have never had a Toyota act like this. Usually speed control maintains the speed uphilll or downhilll in a very small range and never races the engine. This is very dangerous and I will not use speed control until I can get this fixed. Taking to Toyota Monday. I noticed that there are quite a few complaints on the internet about this exact problem.

The cvt transmission make a sound unknow the dealer say me that is all normal in the car for me is not normal other cars contain cvt transmission and this sound not make in others cvt transmission is more making sound in climb and when on air conditioner.
