2019 GMC Terrain: transmission slipping

Filed Jul 3, 2026 · Transmission · IL

No engine lights are on. When at stops it starts chugging and when I accelerate sometimes it does not go like it should. It idles high and feels like it is slipping. I have almost been hit in the rear several times when this happens. One lady did rear end me but the damage was so little that I did not call the cops. This vehicle has not been inspected and it is available for inspection at any time.

I bought this Terrain brand new from Betten Baker Chevrolet in Muskegon Mi in 2019 with 500 miles. That same year we had transmission Slippage causing it to slip out of gear then slam back into gear while driving. I took it to the dealer to have it looked at. They did nothing and informed me it was known by the manufacturer that this was an issue. I then had to bring it back for electrical issues as the lights would all start going off in the cab including dome lights and shift buttons. All key fob would not be recognized by the car and would have to be reprogrammed counting 5 times now. Now I am sitting at just oflver 100,000 miles and what I thought was going to be a simple spark plug change gas turned into a complete motor failure. did an oil change and there was no oil in it. The turbo was replaced and now the engine started making a lot of rattling noises and just stopped. the dash says service transmission, ECS, Extremely low battery voltage and has jost die after oil started pouring out the bottom of the car. It is now sitting at the dealership service department where I was told by am employee there that they have been seeing them come in at 150,000 miles for complete rebuilds and mine was early. let me tell you that this car isn't even paid off yet. And the 2006 Ram 1500 is more reliable.

My car automatic transmission is acting up when shifting from gear 5-6. It slips and it feels like the car is on Neutral for few seconds ( the engine RPM goes up to more than 4000 RPM)after it shifts to the 6th gear. When It shifts it feels like somebody hit us from the back. This is happening in internal roads, intermittently and on speed around 30mph. I'm worried this will cause the cars behind us to hit us when it happens. Everytime it occurs my baby starts crying. I'm concern about the safety of my family when we drive this car. I took the car to the dealership multiple times and they said that there's nothing wrong with the car.

I bought this car a couple of months ago. This problem didn't happen when I took it on a test drive from dealership. It happened after I bought it. Specifically when I start driving it more often. Sometimes a slipping occurs when shifting between gears 5-6. This happens intermittently on internal roads, not at high speed. When the car shifts the RPM goes up to 4000 RPM, sometimes even more, it feels like the car is in neutral for a few seconds, before it switches to the 6th gear. I have to remove my foot from the gas pedal to not let the RPM get very high. When this happens it feels like somebody hit us from the back. Last time my baby started crying when this happens. I'm a little concerned about our safety when we drive this car. The issue is that this problem is difficult to duplicate. Sometimes it happens more than once in 1 day and sometimes it doesn't happen for a while. I did some research online about similar cases with GM SUVs and some said that their problem was resolved after changing a defective valve Body and TCM and some said it's the clutch. It also can be transmission fluid but this car has a low mileage (28500) I doubt the transmission fluid need to be changed. Based on the GMC maintenance schedule, the transmission oil should be changed when this car reaches 45k. I took this car to the dealership multiple times, they check it and they tell me that they're unable to duplicate this issue. I'm not sure what else to do! I love this car. I'm disappointed that I had to deal with this issue that I believe is a safety hazard and could cause accidents. I need your help please!
