engine will go to limp mode shut off engine wait a few minutes and faults go away after restart-- average bout twice a month ??

only way to unlatch is use the key manually at key hole

Car slowed down to about 5 mph. Parked immediately now it wont start. Ive disconnected the battery, will crank but will not turnover.

I do not know what this display means. It stays on. I have no idea what to do. I just bought the car and dealer told me it was weak battery??? Is this correct? Is it safe to drive? What should I do?

what are my options. it isnt running hot but keeps dying, and when its not dying its running horrible. wont go, cant gas it, thought catalytic converter. the exhaust is not being released. cant get the bolts off myself so guess its gotta go to shop, just dont wnt to get ripped. thanks for your time

Seems to be a computer problem. Which module of the computer should I look at replacing and how much does it cost?

AC at any point (whether hot or cold) will not turn on when the button is activated.

When I use the key to open it, alarms go off.
The lid does not latch to close.

Trunk latch on the blink since I forced it to shut with a large box in trunk. Will not open electrically with key fob or interior button. Hard to shut trunk manually. Warning sirens go off when I use the key to open it. Help!

Working backwards:
1)This morning when turning the ignition switch all the dashboard lights flash and the headlights flash along with a clicking noise but the engine won't turn over.
2) Yesterday the warning message panel went through an entire series of random warnings of numerous falts when I started the car. I had to turn the car off and restart the car and no messages were there the second time.
3) Five days ago when I started my car I saw a transmission fault message. The car popped into reverse, I backed out, popped into drive. Turned off engine and after restarting it popped into drive. Could not get out of first gear no matter what I tried so I drove at 32miles per hour at 2000 rpm for an errand. Drove back home, parked, 40 minutes later restarted car and everything was perfect with transmission.
4) one more item, many times lately when I first start the car, I get a buzzing noise from the speedometer and the needle shakes and vibrates at the below 0 mph indicator.
Is the computer going bad, the electrical, a combination?
