2015 Chevrolet Suburban: hesitation when accelerating

Filed Aug 18, 2023 · Transmission · IN

When I attempt to speed up or slow down my truck hesitates, and it's followed by a significant shake, like a shudder, and sometimes it just jerks, or clunks, like it's doing a very “hard shift” when the automatic transmission changes the gears. Sometimes it shifts so violently, I feel like I got hit by another vehicle. I've also tried to accelerate into traffic, and the truck hesitate and then abruptly and violently jerks into gear. It creates a big traffic safety issue! Other times the transmission shifts gears so hard that it slams the truck forward, and makes feels like I've been rear-ended. Now it barely shifts!

Especially at night, the "welcome lights/reverse lights" of a chevrolet suburban confuse me because I think that person's vehicle is backing up. This causes me to either hesitate or at worst, panic if I think they are about to back into me. The photo attached is of a different gm vehicle, the gmc terrain, but the appearance is the same.

We have multiple problems with our new suburban. After traveling slowly or coasting in traffic, when I try to accelerate the vehicle won't go and when it finally decides to go it shudders and vibrates badly, it also does this from a complete stop, been to the dealer 2 times so far this and the last time they told me "it is a normal characteristic of vehicle". It is a very bad one and it will cause a wreck! The radio display flickers all the time even when back up camara is on, gm has no fix for this yet either! The vehicle sticker says it has heated/AC seats, it doesn't have A/C seats, they are airrated from the air in vehicle, that was a total misrepresentation of the product on the sales sticker. Gm rep had us test drive another suburban and we drove 3 different ones and not one of the others did the things our does. When we informed gm of this they said sorry we don't qualify for a buyback/replacement. Gm doesn't care to help and its their very expensive product. I hope no one dies or is injured from the hesitations that gm know these vehicles have that is 0.7 seconds before the vehicle will engage or reengage when excelerating from a slow roll or a complete stop.
