Easy way out? I guess that would be to get rid of the car. Now, if you are looking for a fix for your drivability problem, you must first find out what is causing it. This process should BEGIN by scanning your onboard computer system for possible fault codes. Please note that transmission and body control faults can also cause engine drivability problems on your car so the ENTIRE NETWORK should be scanned. Please note that MOST generic OBD code readers CANNOT perform this function.

If all three brake lights are on, I'd say the problem is in the switch by the brake pedal. Take the cover off below the steering wheel and inspect the brake pedal and the switch. It may be as easy as spraying some silicone lube on the actuator. Try to do a search on this forum for brake light switch.

Hi!!

You may have a defective fuel level sendigng unit or wiring. It should be part of the warranty coverage. Check with your friendly dealer :)

Good luck

OBC uses injector pulsewidth to measure the fuelbeing used. The gauge uses standard sending units.
Standard sending units are notoriously inaccurate partially due to the way they work. Gas sloshing around in the tank can change the gauge reading. In my Suburban when i put on the brakes it says empty. When I accelerate it says half full. sitting still is 1/4.
However if you feel it is still too far off you can always have them replace the dash unit.
