@006 lucerne I'm driving down the highway at 70mph and the fuel cuts out until I drop to around 50mph and then it kicks back in. Any thoughts


Are you sure it was a fuel problem? Speed sensors, Throttle position sensor, cam and crank sensors, tepmerature sensors, map sensor all contribute signals to the engine control module so it will operate the engine in the most effective way . The best thing to do is to have a diagnostic test done on it to find which components are causing the symtoms.

How to get error codes on 09 buick lucerne?


There are many probable causes why not start your car. As a battery in poor condition or a problem with the distributor and the starter motor. To get the codes you need to connect a scanner or do the last bridge between two pins on the right side in the OBD connector and see how many times the check engine light flashes. But if your car has no current will most likely need to change the battery.

I have a Buick Lucerne CXS and the stability track service light came on once and stayed on for the duration of the drive. After starting the car again after rest the light did not come on.


Sounds like a problem in the ABS system. Certain problem in the ABS system will disable the traction system. You will need to have the compue\ters scanned for codes in order to find out what part of the system is having a problem.
