My 2006 Buick Lacrosse suddenly started pulling to the right and became very hard to steer. Then the "Charging System Failure" warning came on. What could this be?

    I have this exact car and year and we just got the rack and pinion fixed and the wheel hub done as well but yet we still have the VES Warning on the dashboard. N the mechanic indicated that he reset but yet the VES warning came back on again. could it be he main component of the system which is an electromagnetic actuator? And can u tell if the actuator is bad when replacing the Rack and Pinion?

I don't have enough info here...but possible the drive belt for the alternator is the same one for the power steering. Electric power assist got damaged and shorted the electrical system.

Do you know if your vehicle has --------------------------------------------------------------------------------
Power Steering System (w/o Electro-Hydraulic Steering) or
Variable Effort Steering System
The variable effort steering (VES) system or MAGNASTEER® varies the amount of effort required to steer the vehicle as vehicle speed changes. At low speeds, the system provides minimal steering effort for easy turning and parking maneuvers. Steering effort is increased at higher speeds to provide firmer steering for increased road feel and directional stability. The electronic brake control module (EBCM) controls a bi-directional magnetic rotary actuator located in the steering rack and pinion. The EBCM varies the steering assist by adjusting the current flow through the actuator to achieve a given level of effort to steer the vehicle. The VES system accomplishes this by adding or subtracting torque on the input shaft to the rack and pinion. The main component of the system is an electromagnetic actuator, which consists of a multiple-pole ring-style permanent magnet, a pole piece, and an electromagnetic coil assembly. The VES system uses the ABS wheel speed sensor inputs to determine vehicle speed. When the EBCM senses wheel speed, it commands a current to the VES actuator that is most appropriate for each speed. The EBCM commands current from negative two amps to positive three amps to the actuator, which is polarized. At low speeds, a negative current is commanded, which assists steering. At medium speeds no current is commanded and steering is assisted by hydraulics only. At high speeds, a positive current is commanded, which creates steering resistance. Ignition voltage and ground are provided through the EBCM. The EBCM has the ability to detect malfunctions in the actuator or the circuits to the actuator. Any malfunctions detected will cause the system to ramp to zero amps and steering will be assisted by hydraulics only and set a DTC.
Are there any other lights lit on the dash ? ABS ?
DTC C0450 Steering Assist Control Solenoid/Motor/Actuator Circuit could have a diagnostic trouble code !
The electronic brake control module (EBCM) commands current from 0-1 amp to the variable effort steering (VES) actuator, depending on vehicle speed. At low speeds, 1 amp of current is commanded to the actuator and the actuator valve is fully closed. A speed increases, less current is commanded to the actuator and the valve opens, allowing pressure to bleed off through a power steering fluid orifice. The EBCM monitors and compares the Commanded and Feedback Current parameters to detect malfunctions in the VES system.
Or you could have a bad steering rack !
Charging System/Generator Fault
Refer to Charging System Description and Operation in Engine Electrical
Alternator problem maybe !
The electrical power management (EPM) system is designed to monitor and control the charging system and send diagnostic messages to alert the driver of possible problems with the battery and generator. This EPM system primarily utilizes existing on-board computer capability to maximize the effectiveness of the generator, to manage the load, improve battery state-of-charge (SOC) and life, and minimize the system's impact on fuel economy. The EPM system performs 3 basic functions:
• It monitors the battery voltage and estimates the battery condition.
• It takes corrective actions by adjusting the regulated voltage.
• It performs diagnostics and driver notification.

    The battery light is on

    The battery light is telling you that there is a problem with the charging system . Not the battery .

One high beam not working 2006 Buick lacrosse


Sampson, sounds like a bunt out bulb, which will need changed.
If you feel comfortable doing it yourself. Basically three screws, and you have to pull one plastic fastener from the fascia (bumper) and pull the bumper back a bit, and pull the assembly out. I believe it is in the manual, not bad to do. I will post a link to tell or show you how to do it. Press the helpful button

My 2006 Buick LaCrosse is saying charging system failureso I replaced a new alternator and new battery.the message came up on the dash again charging system failure...what does this mean what do I do?


This could be a bad connection. First step is to clean your battery connections, then work your way through the wiring. Common places are the starter connections, and body ground connections.

I own a 2005buick lacrosse I was driving in snow and I was doing donuts (don't ask) now my steering wheel is extremely hard to turn, what could it be and is it easily fixable"


putting all the variables together( splashed up snow, high rpms, quick actions of the steering wheel requiring constant pump pressure and the sudden loss of power assist) I would suspect that the power steering belt is loose or missing or needs replacing

It sound like two or three separate problems, but it's hard to tell. The seat belt warning could be a faulty switch which senses a passenger in the seat, while the trunk lid opening could be a battery problem in the key fob. However, if the door locks still work with the same key fob, the problem is more likely with the lock on the trunk. Not starting after stopping could be a battery problem.
