problem #5

While driving at slow speeds the transmission will suddenly shift extremely hard into first gear when while lightly increasing speed. The transmission will shift extremely hard into first gear while gradually coming to a stop. Occasionally while driving slowly (parking lots) the transmission upshifts to second gear causing the car to lurch forward nearly causing a collision. This is a continuing problem that cannot be repaired at the dealership.

I purchased my 2017 Yukon denali in 2017. Since the day I bought it I have noticed a problem with appears to be the transmission. I will be at a stop then I accelerate and the car has a hard shift forward. It tends to pull forward all of a sudden but very violently. I have taken in my Yukon to the two GMC delerships in my area several times. They have serviced it and even performed a transmission flush but still the problem has always continued. I have been dealing with this Yukon problem for two years now. Its so dangerous to drive.

I have taken it in to the dealership several time for inspection. The first time involved a repeated vibration while driving. The resolution was to change or flush the transmission fluid to get rid of any metal shavings. Since then I've taken it back into the dealership twice with reports of jerking, a delayed start when accelerating, and most recently a lurching when shifting between reverse and drive. Each time they have said this is normal.

Transmission shifts are very rough in slow traffic with as much as one to two second delays in shifting into gear with a loud thump. It is so rough that it feels like someone may have ran into the your back bumper. It is also bad enough that it startles the driver and could be a safety issue. GM is saying that this is normal for this eight speed transmission. If my car, the one I'm driving now, had this same problem I would definitely replace the transmission. This is a 2017 denali with less than 5000 miles on it. Online there are many complaints about this and it seems that GM is trying to wait the public out now that the new vehicles have a new ten speed transmission. The dealer told me they could not fix the problem and we would have to live with it. Again, this to me is a major safety issue.
