I would check the fuse box for a blown fuse

It is at the back of engine , at bottom of transmission bell housing in center

Will probably require a software update from the dealer

iring, schematic, electrical diagrams, torq setting, error/fault codes, full assembly/dissembly, service instructions and a lot moreetc are basic contents of these online books they here on this website https://big-manuals.com/

The air struts have a safety valve in them you would have had to crack the line and let the air slowly leak out

Camshaft cover ends, two of them.

I had mine replaced when this happened to mine some years ago

Probably a lot more thing you could change throttle body, MAF, sensor, plug wires and many other thing. You would help yourself by finding out what codes are present if you have a check engine light. If you do not have check engine light I would make sure there are none before spending any more money. Where I live most auto parts store will check your codes for free.

who ever you are getting to tow the car shouls know if your towing your self be sure to call a professional tow service and ask them how because they deal with these problems on an everyday basis>>any replacement parts auto parts shud be purchased here>> Procellular Services News Reviews and Deals Online

Sounds like a starter trying to go out on you. Apparently you have a dead spot or two on the stater (windings) inside the starter. Have you tried having someone turn the key while it won't start and you tap on the starter with a small hammer? Hitting it too hard will damage it. If it starts after one or two taps it more4 than likely is the starter for that jars it enough to make the stater move a bit to make contact and start the vehicle. Hope this gets you headed in the right direction. Jesus loves you, John 3:16-17 (KJV)
