Vehicle is jerking and shuttering while in motion between 4-20mph cold or hot and A/C on or off. This occurs before braking and seems to jerk forward. Tends to occur more often in parking lots. This issue is accompanied by aggressive engine shaking and all passengers can feel the rough idle. This issue is progressive getting worse with time over the last few months. Took vehicle to dealer, spark plugs was the assumed issue from technician. First diagnosis was spark knock. Replaced spark plugs, did not fix the problem. Second diagnosis was "off center steering wheel causing stability control to override driver throttle inputs and lead to jerky operation" case is ongoing and a resolution hasn't been provided or solved. Toyota Corp. Is opening an investigation/case.

Between 10 and 20 mph occasionally, not always, there is a hard shift that doesn't feel normal. It is usually under light acceleration and conditions. Even trying to mimic it under the same exact conditions, sometimes it will simply not do it.. sometimes it will be a hard thump. Other times it will feel premature. (shifting before it should) I wanted to believe it is the transition from the launch gear to the cvt but the timing of the transition and the degree of the hard shift even under the same conditions tends to vary considerably.

Vehicle has a very hard shift out of launch "first gear" when low on fuel or the engine is cold. Dealership (sheehy Toyota in fredericksburg va) and could experience the same feeling on light to moderate acceleration. I informed the dealership that the feeling they were experiencing is minor compared to what it usually feels like when driving. They experienced the same thing when driving another 2020 Corolla off the lot with light to moderate acceleration. Then a day later they drove another 20202 Corolla supposedly for another 30 minutes and could not duplicate the hard shift and noted that when driving both the customers car and a new car the shift feeling varied from time to time so there was nothing they would do. They also said they contacted the engineers at Toyota who said that this hard shift feeling was normal. Looks like Toyota is back at it with just deny everything and hope the problem goes away. Very unhappy with my experience especially with how Toyota has handled this so far. I will not go away until they fix this problem.

2020 Toyota Corolla SE -(vehicle purchased new) (cvt transmission) upon minimal to normal acceleration vehicle makes a hard shift feel like a bump kick in acceleration of speed between 8-9 mph. Will feel more of a hard shift at times if coasting with minimal speed then to the normal acceleration (start and stop traffic type of conditions). Periodically once reaching to speed of 36 mph seems like the transmission is starting to slip then continues with normal operation. While sedentary at stop light vehicle has had loss of power in and out near stalling out. Separate occasion without the air conditioner being on, a rough idol took place. At times if put in sports mode shifting is smooth without too much trouble; with exception of at higher speed open road removing off the gas pedal will make a whining high rev noise like the transmission went out and did not down shift even with pressure applied to the brake. Will then down shift after approximately 15-20 seconds. Lane departure indicators have gone off without there being a correct response for that action taking place. Vehicle has been owned for less than ninety days and appears to continually further in its defects.

07/09/19 - three days after taking delivery of a brand new 2020 Corolla sedan, my car stalled in the middle of a busy city street. I was stationary with foot on the brake waiting to make a left turn. When I took my foot of the brake and attempted to accelerate, it had a complete power failure. Red warning light came on saying engine power low. I was unable to start the car again for several minutes. I was nearly hit by cars going around me. I took it to the dealer for service and there were no error codes and they could not duplicate the problem. 08/06/19 - my brother was driving on a highway in stop and go conditions during rush hour traffic. With his foot on the gas pedal, the entire vehicle jerked or jumped several times in succession, stopped and then did the same thing twice more. It felt as if it was going to lose power or not getting enough gas. I took it back to same dealer for service. Once again, no error codes and they were unable to duplicate the problem. Service foreman told me those 2 incidents were definitely related. I reported both issues very dangerous incidents to Toyota customer support as I feel that I am driving an unsafe vehicle. At first, they were receptive and even sent a Toyota factory representative to inspect the car. Then my case manager told me they found nothing wrong and "could not verify my concerns". she said there was nothing more they could do and there were no repairs to be made. After doing more research online, I found that the 2019 Corolla hatchback was recalled in December 2018 to replace the cvt transmission due to a manufacturing error that could cause loss of motive power. The info I read stated the exact same engine is in the 2020 Corolla sedan, but it has not been included in a recall. I am very concerned for my safety, as well as that of my passengers, and other vehicles.
