While taking a curve at a high rate of speed seems like fun, it can also be quite dangerous. Luckily, there are a number of systems on a car that can...
For vehicles that have anti-lock brakes, the wheel speed sensor plays an important role. They work together with the electronic stability control system that is found on so many vehicles today....
Once upon a time, your car’s steering system was pretty straightforward. Today, this isn't really the case. As more and more electronic systems are added to our vehicles to enhance stability,...
A stabilizer bar is pretty much exactly what it sounds like – a metal bar that helps to stabilize your car. It plays a significant role in handling, particularly around sharp turns....
While the car may be safe to drive, I would not recommend driving it with these codes on as many of these can cause a chain reaction of issues when one component is failing. I suggest having a local expert,...
GM issued several service bulletins which appear to deal with this scenario (TSB Service Bulletin Number: 10342498 &10574399 ). Check with your Cadillac dealer.
Hi there, thanks for writing in about your 2009 Buick Enclave. You may have one or more wheel speed sensors giving erratic readings. I would recommend having the system scanned to get the codes to see what sensor is causing...
VSC stands for Vehicle Stability control. Trac stands for traction control. Both systems have various sensors that they share to obtain the information they need to do their job. If they are coming on together, it means there is a...
This sounds interesting. I have not experienced such a situation before. I can't imagine a small bump causing such damage unless the vehicle crossed over the object with the rear end and possibly bent something. You may want to at...
Your Sentra is equipped with a stability and traction control system called the Vehicle Dynamic Control (VDC). The VDC system is designed to provide better traction during slippery driving by reducing engine output. This reduces wheel spin and can help...
Hello. These systems are interconnected, since both of them can control individual wheel brake functions when operating. It is likely that one of the speed sensors are failing. To have this verified, have a qualified professional, like one from YourMechanic,...
There is likely a wheel speed sensor issue causing the DSC light to be on. It also sounds like your transmission is in "limp' mode - being stuck in 3rd gear. The problem codes, and professional interpretation, will provide more...
Hello, thank you for writing in. There are several reasons why the traction control and check engine light might come on. There should not be a direct relation between the oil change and the warning lights. The spark plugs may...
Hi there. The VSA light is on indicating that the traction control is active. This will turn on the brake system and try to control the vehicle in the event a tire will slip. The wheel sensor on the left...
Your car is equipped with wheel speed sensors at each of the four wheels which monitor wheel speed while relaying this information constantly to the ABS and traction control system which are controlled by the car's ECU. When the ECU...
The ABS and AdvanceTrac systems share the same sensors and can turn on the service lights for both systems at the same time if there is a problem in one of the systems. When the ABS or AdvanceTrac light is...
Hello - these are likely unrelated problems - although all frustrating. The engine misfire will require further diagnosis based on ignition codes. There was likely another problem code - perhaps for an ignition coil or misfiring plugs issue. It is...
Hi there. The VSA (Vehicle Stability Assist) is on for an issue that deals with the engine load. Check the codes that are stored or pending in the ECM (computer) since the check engine light is on. The code should...
Hello, thank you for writing in. The VSA warning light relates to the vehicle stability control system. It functions with the ABS system to keep the vehicle on the road in difficult driving conditions. There are multiple sensors and systems...
Hi there - when the "VDC" light is illuminated on your dashboard, that means that Vehicle Dynamic Control is "OFF". It should be "ON" normally, so that it automatically steps in to reduce power when wheel spin is detected during...
Hello, thank you for writing in. The vehicle goes into a safety mode when certain components do not pass the system tests that are run when the car is started. Since the codes were set the last time the vehicle...
Hello, thank you for writing in. The VSA (vehicle stability assist) light comes on steadily when there is a problem. If it blinks, it means the system is actively working to control the car and help it steer. If the...
The light could have come on for the brake fluid could be low and causing the system to see that the brakes are not safe. For the engine loosing power and making a knocking noise, there could be a misfire...
One of the vehicle speed sensors is most likely malfunctioning and signalling the ABS anti-skid to think the wheel has stopped when you are moving. You will need to have the systems scanned and checked for stored codes and test...
