Hello. Two things that could be causing your the issue on the Sorento are a twisted power steering hose or a faulty new component(power steering rack, PS pump). I suggest you check all power steering hoses to make sure they...

Hello - most often, wiring damage is caused by shorts caused when wiring insulation is damaged and cut or worn away. The big charging cable from the alternator to the battery (or the starter cable) has a huge capacity for...

Hello. Thanks for writing in. The universal oxygen sensors, a bad connection, or a bad catalytic converter can all be the cause of the codes. If you can you access to a known good oxygen sensor and test it in...

Hi there. When a car has issues accelerating, it is usually caused by a restriction of fuel, the fuel system's inability to properly mix air to fuel or an exhaust leak / vacuum leak of some sort. It's a good...

Hello, thank you for writing in. The color and condition of the transmission fluid should be a huge indicator. Low transmission fluid is one of the leading causes of issues with the transmission. You will want to start by refilling...

The noise is the drive belt slipping on the pulleys on the engine. Check the tensioner to see if it feels loose and not tight. If the tensioner is loose, then I recommend replacing it. Also if the belt is...

The on-board capabilities of your Kia are pretty high. When problems occur, the computer often memorizes them. A lot of times, it will turn the engine on and have the Check Engine Light on and give you a code that...

P1318 relates to spark plug voltage detection. This function might be integrated into the DME on a BMW. If not, there will be a module (VDM) and the code will typically refer to an open or shorted wiring harness. Diagnostic...

The brake master cylinder is most likely leaking internally; it needs to be tested, replaced then bled out of air. If the system fluid is not low, then this is the most likely cause. I recommend that you have a...
