I have a 2007 Hyundai sonata. When I was driving ang I accelerated I lost power and all my lights on the dash came on and my radio went off.

Hi and welcome to FixYa,

Offhand, definitely an electrical issue. Some ideas to check, consider and/or explore:

• IGN switch - check for loose, corroded or heating connections. To test, under normal usage of the vehicle, should feel warm but not overly hot. If so, then possibly loose connection;
• fuse/relay box - check for loose, corroded or burned terminals, holders, clips and connectors/pins. Use an electrical contact cleaner and spray. It may also be necessary to scrape to remove burnt marks/corrosion;
• fusible link - the battery would have 2 wires connected to the + terminal. The big wire goes to the starter, the smaller of the two is the electrical systems main wire. This normally goes to the fuse/relay box. Check for frayed ends, loose connection, corroded terminals. In some instances instead of being at the battery's + terminal, it is connected to the end of the big cable down at the starter motor.
• ALL connectors with big wires - these carry the main +12 either as always ON, ACC or IGN. If a connector has a wire bigger than the others, check them. It may be necessary to disconnect to enable you access to the inside pins/terminals. Scrape them clean.

after you air the tire back up to the proper pressure the tire indicator should go off in 10-20 miles

Remove the facia plate, and remove the 4 screws that hold the radio in place. It's actually one of the simplest cars you can do.

Ok there are two ways you can do this . you can just pull the negative batt cable for 10 minutes. this will drain all power out of the CPU(ECM/PCM). or, you can use a diagnostic scan CPU to erase the codes and , reset the light.

Look under the bumper and you will see two large phillips head screws right in front of the wheels. Take these two screws out and bend/move the plastice piece out of the way. Now you can easily get to the bulb. There is a cap that twists off that protects the wires and back of the bulb. Twist this off and then remove the plug portion from the back of the bulb. The bulb then turns 1/4 to 1/2 revolution to loosen and remove. Reverse steps for installation.
