Excessive soot and carbon (pre-maturely) from the EGR system is most likely clogging up the intake system, throttle body, etc. Although the dealer is supposed to be responsive, if you are having further issues, or would like a second opinion,...

If you have went as far to do compression and leak down, I’ll assume the problem is not obvious. After those tests, you can be almost sure the mechanical components of the engine are good. Is it a random misfire...

Thanks for your question. If it's a wheel bearing, the noise generally doesn't go away with speed although it might appear that way because the noise gets masked by other noises such as road noise, wind and exhaust. It is...

It sounds these are two separate issues. The clacking noise could be dozens of things, however, these engines are known for having noisy timing chains. A professional mechanic, such as one from YourMechanic, will be able to listen to your...

Hi there. This is a problem that comes up often on this car. The most common problem is a leaking intake manifold gasket. This gasket fails and causes a vacuum leak which will make it run rough. Not replacing the...

Hi John. Thanks for writing in today. The CV boot protects the CV axle from dirt, debris and maintains lubricity as it contains a copious amount of grease. It will wear out overtime - due to exposure to elements, road...

Your car’s tire pressure monitoring system is designed to track the pressure in all four tires and alert you if one (or more) of them drops below the safe threshold. If the Low Tire Pressure light in the dash comes...

Hi, thanks for writing in. In order to know what is causing the lights to come on, you would need to have the ABS module scanned to see what codes are stored. You could be low on brake fluid or...

The light will not reset itself until you have the new sensor communicate to the TPMS module. This takes a calibration process that most any tire store should be able to do and some mechanics that have the proper scanner...

Hi there. When you wiggle the wires to the kill switch and the gauges start to work, then the contacts inside the switch could be broken. You could replace the kill switch with a toggle switch that will do the...
