My college son was driving down from Orlando, and when he got here I took his/my car to my mechanic because the AC was not cold. I felt a hard shift when I put it in reverse, and when I started to drive the car to the mechanic, it didn’t feel right. They fixed my AC and I asked him to check the car as I was worried it did not feel safe to drive. They changed all the filters and did a complete transmission flush even though it was not due for 60,000 miles and there is less than 54,000 miles on this vehicle. They changed all the filters and upon doing the transmission flush my mechanic of 15 years found chunks of metal and shavings in the transmission pan. He took pics & told me my transmission was bad but it was an internal defect and I needed to take it to Toyota as there was no damage on the outside of my transmission, it’s pan, gasket or filter and there were no signs of any leak. He told me these CVT transmissions were a problem and there were a lot of ones not recalled, but there was a Special Service Campaign JSD for 1.3 million of these transmissions from Toyota. Toyota said my Vin number was not part of this Special Service Campaign JSD but I found there were also 3400 recalls on the CVT transmissions from the Toyota hatchback. Toyota told me because my car was already out of warranty, even if it was a manufacturing defect, they were not responsible. I take very good care of my cars. I have two Toyota Corollas, both 2017 and now I am very concerned about the other one. I’ve been on a lot of Toyota forums and it seems there are so many other Toyota Corollas that don’t have many miles on them and all of a sudden their transmission has an internal defect. I brought it to the dealership and they simply said it needed to be replaced, that it was hard shifting when going into reverse and banging gears intermediately. They told me if I wanted to know what the defect was I would have to pay at least 15 hrs of labor to start. My son could have been killed driving it

I had to drive around 600 miles to and from family funeral. As others have reported the cruise control on a down hill slope goes out of control. As I reached the top of a hill and started down the cruise control would accelerate to 4000 RPM ( it is really loud) the speed would start increasing and go 15-20 MPH over what the cruise control speed was set at. I had to turn off the cruise control to regain control over the speed. I was afraid that something might happen if I did not. Where it seemed my car should down shift it was not. Something is wrong with the programming of the cruise control. This should not happen on a decline. Also, at one point when I was in the left lane and a car passed me on the right, my car slowed down really quickly. If someone had been behind me it could have caused a serious accident. This is my fourth toyota and I have never had these problems before.

My car was in drive and my foot was on the brake so I was not accelerating. I was in a turning lane to enter a business. My car shut off completely and the lights on my dash lit up. I waited a few minutes and took the keys out of the ignition and was able to start the car again. I've also had issues in the past, on multiple occasions, where I turn my key in the ignition and the car will not start. This issue has happened multiple times (even when it was brand new) and no one has been able to duplicate it as it happens randomly.

Shifting of transmission in vehicle hesitates and/or is inconsistent upon sudden acceleration or deceleration, making it difficult for the driver to determine the acceleration of the vehicle versus other cars on a busy street. There have been numerous instances in which the car is not shifting appropriately and I am unable to accurately judge entering traffic from a residential neighborhood onto a busy intersection as the car will sometimes shift/react to the driver and other times not. At times the transmission reaches and remains at 7, 000 RPM (in red) without shifting and/or is slow in response to acceleration. A campaign recall was issued by toyota for which the transmission software was reprogrammed on the vehicle; however, these issues still remain. My ultimate concern is the safety of my children and myself when driving this car as I am not always able to predict how it will drive upon sudden needs to accelerate or decelerate. It is most notable in stop and go traffic, stops on a hill, or need for increased acceleration getting on the highway. Weather temperature, high winds, passenger load all seem to be variables in how the car shifts. The car drives/shifts inconsistently from day to day. When not shifting, it raises major concerns I will make the wrong determination when judging traffic that may cause an accident. I have consistently raised these concerns with the dealership from the time of first oil change (purchased new) to current (31,000 miles). Toyota has also reviewed; however, I am concerned there is bias in the true operation of the vehicle as there comment was "driving as designed'. It was stated by toyota that it costs several million dollars to update the software and that it would not be updated until enough of these cases were known. I am submitting this request for an independent review of the transmission issues in this model year.

Toyota special service campaign jsd. Understand that toyota has notified dealers there is a know defect with the CVT transmission. However, as an owner I have not been notified. Transmission does not operate smoothly when driving. Toyota is attempting to correct with a software update, but they are not actually disassembling the CVT transmission to check for problems\unnecessary wear. This needs to be a recall, so owners will be covered in the likely event the CVT transmissions break in the future due to the known defect issue and the vehicle is out of warranty. Appears toyota is trying to save money by not issuing a recall, and just trying an inexpensive and inadequate software update with investigating whether the problem has caused damage to the transmission.

Vehicle was stopped at a traffic light and when the light turned for a left turn I tried to accelerate to get through the intersection when the vehicle lost power. This has happened on three occasions and I took it to the dealership to get it checked and they said they could not replicate it. Transmission has not been shifting correctly and now the transmission is making a strange grinding noise. This corolla has a CVT transmission and the toyota corolla forums are telling me that toyota is aware of this problem and had issued a special service campaign to update the software. This has since been rescinded because the update did not fix the problem.I have read that this loss of power is causing some serious safety concerns, especially if it happens on high speed highways.

While driving down a downgrade with the cruise control engaged and set to 65mph, the CVT transmission seemed to downshift, the RPM's increased and the vehicle accelerated to well over the speed limit. It felt like I was losing control. I had to activate the brakes to disengage the cruise control in order to reduce my speed to below the posted speed limit. I tried it again on another downgrade and the same situation was duplicated. I did not take the car into a dealer since the issue has been reported to dealerships with a solution to this problem.
