While driving my vehicle, it started to shudder and shake. The Vehicle acted like it didn-€™t have any power. I was on top of a hill, and the car would not go. I tried park, drive, reverse and nothing. I had my 8 yo in the car in a dangerous area. I had to put the vehicle in neutral and drift down a hill, hoping no one would be coming to get to a safer place to get help. My car was towed. When they flushed the transmission there was metal shaving, which I now learned this has been an issue with these power trains. My vehicle is just at 60,800, which is just 800 miles over the gmc warranty.

Transmission failure at 66,909 miles on 5/19/21. Dealership has original replaced transmission. Our safety was put at risk by breaking down and not being able to move vehicle to a safe location. Advised by service agent at dealership that a lot of 2017 Chevrolet suburban transmissions have had problems. The problem was confirmed by dealership and a remanufactured transmission was installed. I have invoice from dealership describing issue and work done. No warning lamps or messages advised of the problem. Slight Transmission slippage started on 5/18/21 complete failure the next day.

Vehicle dash and headlights turn off while driving, engine stalls and dies, power steering becomes inoperative. Transmission pops out of gear and freewheels. Service stabilitrack light. Very dangerous situation for my wife and 5 kids when this happens on curvy backroads at night like just happened last night! this is also the same problem as our previous Chevy Tahoe so we knew the problem was likely related to poor quality battery cables that are degrading prematurely. This should not be happening on a 3-4 year old vehicle. After searching a GM web forum and finding other people complaining about the same issue, there was a reference to GM tsb 18-na-161 on this exact issue I am absolutely amazed that GM has not done a recall on this yet, as it is a major safety failure likely to cause a crash and potentially a fatality. I checked the tightness on the connections by hand, which were both very tight, then I reseated and torqued the battery terminal connection. I measured the resistance across the power jumper, lug to lug. This is GM part number 84494554, and I measured 0.3 ohms across this little section of wire at multiple points on the lugs. Trimming back the insulation and continuing the measure, the highest resistance appears to be coming from the wire to the lug connection at the fuse bus, and not the crimp connection at the battery terminal, and not the bolted connection to the bus. There were some strands broken at this connection. I made and added a temporary jumper of the same wire gage, and the resistance across the same measured points dropped to 0.0 ohms. Absolutely a major safety issue if the vehicle suddenly dies without warning. I can see this same issue happening once, I forgave GM once years ago, but with the same issue happening to two different vehicles 8 model years apart, the safety of my family is too important to buy GM product in the future.

On 3/25/20 at approximately 7:20pm I was traveling a North bound direction on us highway 51 in lane 1 (fast lane). My 2017 Chevrolet Suburban started to jerk and the RPM gauge excelled to 5/6 RPM. Then, the Suburban came to an abrupt stop in the middle of lane 1. at that time I was rear-ended by a law enforcement officer. The officer was unaware I was stopped, because I did not have any indications such as brake lights. I was trying to press the accelerator pedal to try move out of the highway, and the Suburban would not move. I had my two small babies in the car and thankfully no one was injuried.

I had a problem with my transmission, I took it this auto shop to fix. He charged me 3200$ to change the transmission however they lied to me, they didn't change it they just rebuilt it. Gave me 6 months warranty. I had same problem 5 months after I was at their shop. I went to them. They said we can fix it but you have to pay. Otherwise we not going to fix it. I paid them to fix it. They made me buy all the parts from Chevrolet dealer twice. After all they told me to buy brand new transmission. Which I did. The car stayed at the shop 15 consecutive days. I lost my job because of their recklessness. I lost a lot of money because of them. The shop name is (37 auto shop. Which located in 37-43 57th St woodside NY 11377.

Car engine revs up to 3-5 rpms then jerks forward, thought I had got hit from behind, luckily there wasnt anyone in front of me this has happend several times. Brought to dealer 1st time they said it was a bent push rod and that it was "fixed, but may happen again" truck wasnt running the same when I got it back still hesitating very slightly. 1/24 at a red light when it turned green, stepped on the gas it jumped so far forward and that my body reacted and I thought for sure I had been hit, there was no one behind me. Happend again, but this time the engine revved 1st. Didnt drive it after this, next day tried to drive it it was revving so fiercly and jumpinh so bad on a 12 min ride that I had to drive with my hazards on on the shoulder of the road in order to avoid getting hit or avoid hitting anyone else. By the time I got home the truck wouldnt even drive the engine was just revving. It was then taken by flatbed to the dealer. This is an extremely dangerous situation for all, and Chevrolet/General Motors needs to remedy this asap

While driving normally on the highway there appeared to be a hard shift between first and second gear and when second gear did kick in, there was a sudden jerk. Already having made an appointment with the dealership the next day, that morning a whirling sound appeared each time the acceleration pedal was pressed. When we got the vehicle to the dealership, they ran a diagnostic and it came back clear. I also pay for on star, and they provide me with regular diagnostic reports, which never indicated a problem and the check engine light never came on. The vehicle appeared fine on paper but with a test run, the dealership was able to see the problem and told us we needed a new transmission. A mechanic took our old transmission apart and said there was a problem with the torque converter and when it went up it sent shrapnel into the pumps and destroyed the transmission. This seems to be a common problem with certain GM trucks
