A clogged catalytic converter can increase exhaust system pressure robbing the engine of power. Along with this overheating, excessive fuel consumption can also occur. The exhaust system pressure should be checked and compared to specification to ensure the catalytic converter...

The powertrain light is on for the transmission may be low on oil or there is an issue with the oil that is in the transmission. Check the transmission oil level and see if its full. See what color the...

Hello, thank you for writing in. Grinding noises like this can be incredibly hard to diagnose. The power steering pump may be to blame. Even if it is not hard to steer, it can make similar noises. Keep that in...

Most vehicles have an internal transmission filter that can be changed by removing the transmission pan. Some diesel trucks will have an external filter that can be changed just like an oil filter. The transmission filter is usually recommended to...

Hi Tristana. Thanks for contacting us tonight. In most cases, if the security system has been disabled manually (meaning that someone has disconnected wires or attempted to bypass it somehow), it will create a fault code in the ECU which...

Noises can really be annoying but if you heard a metallic grinding noise, then generally, that's metal on metal and you are going to see shiny things where it is rubbing. So look for shiny things near the area where...

Hello. If these issues started at the same time then it sounds like there is an electrical issue. It may be a bad connection or a failing alternator. I usually start by load testing the battery and checking the battery...

We need to determine if your vehicle is actually overheating, or if the gage is just reading incorrectly. If your vehicle is overheating; you will no doubt have boil over from the radiator or reservoir. The fact that your gage...

Your tire pressure system uses sensors in each tire to signal the pressure in the tire. The sensors are known to go bad and will cause the system to see it as a pressure loss. This does not mean you...

Hello. When a vehicle sits for this long there can be a number of issues keeping it from starting and running right. You do need to replace the battery,and you should replace all of the fluids before starting it and...

You should try and turn the engine manually on front of crankshaft pulley to see if engine is seized. If engine turns over by hand then problem will most likely be the starter. If you cannot turn motor then it...

Hello, flushing the coolant system involve removing the thermostat of the engine to do a complete job. The contaminants in the system can block the thermostat’s passage way. When you have this type of break down with coolant it...

A loud sound like that you are describing would suggest an internal mechanical failure. You might check engine oil pressure which will give you some clues. If a part cause is low oil pressure, due to excessive clearances (which in...

Hello. There is a big concern with the air bags on this car. If the car is, or even "was", equipped with a Takata airbag, I wouldn't consider purchasing it due to the Subaru Recall. Even if the airbag was...

I would suspect that the steering is electronic and something was not making contact when you were going over the bumps and caused the steering to lock. It could also be a programming issue or a steering sensor issue. Have...

Hi. There is something still draining the battery. There could be an interior light staying on and you don't realize it. Car chargers can also drain the battery when the car is off. There is also the possibility that the...

Hi, thanks for writing in. I suspect your "upstream" sensor is the primary problem, and should be replaced. The downstream sensor you did replace is really measuring whether the catalytic converter (the main cat, not the pre-cat) did the job...
