general problems of the 2006 Chevrolet Uplander

Have a braun van where I was sold a unit that the rails and floor are rust out and van is getting ready to split in half was not disclosed that it was ther and the unit had a recall in 2016 purchased ot in 2018.

My vehicle is making a sound that varies could be suspension but it sounds like grinding and or howling mostly while braking or increased speed.

When I'm stop and I press on the accelerator the van jumps or it starts shaking I took it to the dealer I was told it was the trasmission. They did a full service oil change and everything on the transmission. And it continues to do the same thing when I press on the gas pedal it doesn't get the next shift and it jumps my passengers get scare it fells like someone hit us from behind . Nothing pops up on the dash board no check engine or anything it's the transmission and I don't want to put money in it . It does it everyday I don't want to drive it I'm scared it won't go when I try to accelerate or it won't get the next gear and I'm going to drive 10 mph.

I own a 2006 chevy Uplander I noticed that when coming from stop it would pull and would pop to go so I have had it checked numerous times have replaced c. V joints, strut mounds struts shocks and still was having the same problem so then I went and replaced all breaks and rotors I have had to replace them 5 times within a year and half I have given up so now the back ones are doing it again but yesterday the break light came on this is the first time I have the I also have the van saying emergency break is on, funny thing now is that when I go and push on it. It don't lock I release my foot off it and it comes right back up to the unlock position but breaks are locked and cant be moved. So I on here looking at all the complaints and I think I know the problem to the one for the breaks the emergency break lines and pedals as well as lines should be replaced and rotor and breaks by dealership as recall due to the fact that this is not wear and tear on a vehicle it is malfunction of emergency break.

My car will only start on the first start of the day other than that you have to keep trying to start it. I usually have to lightly tap on the gas pedal to get it to start. At least 2-3 times a day it will keep turning over and die. I'm afraid that it will cause a fire or something because of that . I've taken it to a dealer at the 14-69 auto mall in fort wayne indiana and he told me that an excessive start in gm vehicles is very normal. I know quite a few people that have this same van as I do and every single one of them has the same exact problem . Bit it seems that no one knows what is causing it. I am afraid it may be an ignition or something similar to it . That k you for your time .
