My road is bumpy and the car seems to bounce a lot, sometimes sounds squeeky

trans grabs or slightly jerks when cold. afterwards from start when warmed up, it shifts ok.

I've replaced the bulb

can run for miles with no issues than it starts with bell ringing notifying me that parking assistance is off, ABS messages, stabilitrak not working, traction control on engine light on, transmission shifts poorly than it goes off return to normal for days than starts all over. OnStar reports a control modular is bad. Dealer had car but after 170.00 said It would need to get worst. dealer said their were many error codes OnStar said they would give codes to anyone doing work on car I believe one was 1u

trainmissions oil run out

lines are leaking

I check my oil and it is not low.

The car has a hesitation when car idles and then stops.

And the brakes is to tight and i can not drive cause there is no brakes so what cause the noises in the manafor and why it keeps shutting off and its going to high on the rpms is going to high when i start it up

Tried to start, i.e., ran for a few seconds, and then shut down. Trying to retstart, engine just keeps turning over. Mechanic replace cellinoid, and cranked. Now will not crank except for yesterday. Sat in Sun all day. Cranked right up. This morning, will not cold start. I do need to do 100,000 mile tune up/service.

Only when stopped I smell it

Dealer said to replaced requires that bumber and grill be removed at cost of $220.00. is this correct.

However, out of the blue the engine has started overheating, with very little change, if any at speed.

Also, electric fans are operating, coolant levels appear to be where they should be and no visible signs of leakage.

Go figure!

We had to replace 3 fuel pump and 3 relay fuses which we bought from
auto zone. Just out of the blue our car won't start. Please help us.
