Front lower seat frame fracture

About 6 mos. ago a/c would not engage. Took it to the dealer and they found a small plastic gear broken in some part and replaced it. I think it some kind of actuator problem.

No matter what my temperature settings are on the passenger side continues to blow only cold air. The driver side will change with temperature settings from hot to cold but passenger side remains the same,cold only.

heating and cooling

The aux for the back seat would stay working when you plug in a head, set at the same time the noise for the direction signal would quite. The same thing doesn't always get it back on

I took my car in to the dealer - tune up. Oil change and they replaced the power steering fluid. I drove it the next day and there was noise and felt like the suspension was off. Took it right back to the dealer and now asking for $1200 to replace the front struts because one is locked and one is "blown". It drove fine before I took it in so I'm truly confused.

My Driver Instrument Control shows also low mph but even that doesn't sound right. It has been back to dealer several times and cannot find anything. Highway is 17, 18. I have used a loaner for a day and the DIC shows the mpg going up and down as I drive. My car doesn't do that -- shouldn't it? Could there be something wrong with a component even though a "light" isn't on at the dash? I calculate my receipts at the pump as well each time I fill up. I am ready to look for another car if this can't be fixed. Any help you are you able to offer is very much appreciated. Thank you.

The manual shows flushing and replacing the brake fluid at 30,000 miles/2years.

The dealer charged me $1,218 which seems excessive. Is there any justification for this.

It almost feels like when you have the cruise control on and it doesn't quite catch up (like on a hill), but this is happening with no cruise control on, and it has happened on level streets at around 20-30 mph.

What is the + or - on the shift lever used for?

The manual says that the rubber inserts in the cupholders on the Buick Enclave are removable. I can't get them out. Does anyone know how to remove them? Thanks.
