Transmission is very erratic to shift, especially when cold. Sometime, when pressing the accelerator, the car hesitates before moving forward. This can be dangerous at intersections with oncoming traffic. The transmission was inspected by a Chevy dealer right after the car was purchased (09/2017) and parts replaced. The symptoms still happen. It was inspected again 01/2023 by a Chevy dealer and the transmission fluid flushed. The symptoms still happen regularly. GM is aware of this dangerous issue, yet nothing has been done to correct the problem.

Since the vehicle was new, it has exhibited a transmission shake or shudder that is especially noticeable when the Active Fuel Management is active. The vehicle was serviced by Chevrolet under warranty on Dec. 5, 2017, for a transmission shake and/or shudder repair using the flush methods described in Bulletin No. 18-NA-355, but it has continued to exhibit a transmission shake or shudder. My local Chevrolet dealership has now diagnosed the vehicle as having a torque converter with excessive slippage and recommended a replacement torque converter at a cost of $3,450 including parts and labor, or a total transmission replacement at a cost of $8,100. My vehicle currently has 24,473 miles on the odometer. A major transmission component should not fail in less than 25,000 miles on a modern flagship vehicle used for light, non-everyday driving from a leading U.S. auto manufacturer.

I have a '16 corvette z-51 w/8-speed auto trans. Ordered car brand new in april 2015 - took possession in sept. 2015. Car turned 6,000 miles in april 2021. On a drive recently, rear end began to experience a shudder/ vibration between 50-65 MPH like driving over small rumble strips. Internet research resulted in me finding the existence of service bulletin no. 18-na-355, dated february 2019 and an updated bulletin with same number dated april, 2020. Problem is a known problem for a host of gm vehicles from 2015-19 with the gm 8l45 and 8l90 8-speed automatic transmissions. Apparently the wrong fluid was installed in these transmissions. Reference attached bulletin 18-na-355. Took car to dealer the following monday and it was diagnosed as having the stated transmission shudder problem as outlined in service bulletin. Because my car is out of factory warranty by 6-months and gm extended warranty won't cover for this expense, I was left to pay the $650 to correct a known issue. Why must owners pay for gm's error? Attached bulletin explains the steps taken to correct the problem, involving 3 flushes and installing new/ different type of transmission fluid - new part number 19417577. Time will tell if this so-called fix works. Internet auto forums indicate some folks have had to return to the gm dealer more than once for this problem, after the flush procedure. Contacted gm and logged formal complaint -- with no response and basically nothing but a run around thus far. As a consumer who paid good money for a high end performance vehicle would it not have been good business practice to notify customers of a pending problem rather than remain silent about the problem, let vehicle warranty run out, then tell customers it's their problem? Poor customer satisfaction policy no doubt! Gm should be forced to own up to this problem and pay for the repair.

Veh purchased 9/2015 and so far I have replace four rear rims and one front. All have hair line cracks on the inside of rim causing radical air loss, vibration and tire wear. Navigation screen flickers and goes on and off at least two times a week and I have to open and close to restart screen. Blower motor went out at 37k miles and the transmission is bucking, vibrating, shuddering and going into 5th gear at 31mph and feels like it is hanging up in 5th gear the clunks down to first at 10mph. Went to dealer, they claimed they did a software up date and things are fine. Left the dealership and came back 5 min later with same issue. Took service manager for a ride and he confirmed the horrible ride. Have to take back on tuesday 5/28 and it feels like the drive shaft or rear end will fall out. They said it was fine. I hope nothing happens to me or the car.

While attempting to accelerate or decelerate my car I feel a hesitation, followed by a significant shudder when the vehicle's automatic transmission changes gears. The shudder, shake and hesitation also occurs while my vehicle accelerates in a single gear, and not actively shifting gears. The problem does not merely result in an uncomfortable driving condition. The shuddering and hesitation seem to be related to internal issues within the transmission and/or torque converter causing friction surfaces, hydraulic systems, and gears to not function properly. There is possibly permanent damage that will occur to the transmission and/or torque converter over time. I face escalating repairs that can include flushing the transmission of metal shavings caused by the defective transmission operation, and which eventually necessitate the replacement of components such as the torque converter, valve body, or the entire transmission. As such, the transmission defect endangers the drivers and passengers of the vehicles, and diminishes the value of the vehicles. Gm's deliberate non-disclosure of these defects artificially inflated the purchase and lease price for these vehicles. Gm has known about the transmission defect for years, since right after introduction of the transmission. Since 2015, gm has issued thirteen versions of a 'technical service bulletin,' or 'tsb,' related to this shifting issue alone. The tsbs related to the transmission issue have advised dealerships to, among other things: complete the 'clutch drive learn procedure,' replace the valve body, replace the entire transmission, flush the cooler lines and cooler, remove debris from and clean the transmission pan, replace the transmission filter, replace the transmission fluid, and flush the transmission. To date, none of gm recommended solutions has resolved the problem.
