When you say "not working well", it sounds to me as though the actuator could be getting weak, since this door gets locked, and unlocked the most. I recommend having the lock actuator replaced, after it is checked. I recommend...

Hi there. If the wipers stopped working on all speeds then the wiper motor may have failed. I typically start with checking the voltage at the motor to see if it is present. If it is not then there may...

Your description suggests you may have a bad grounding problem, a short somewhere, or potentially a failing voltage regulator. The voltage regulator regulates the power charged to the battery by the alternator to ensure that the battery is not over...

Hello Sarfaz. Firstly, a few things I would check is your radiator cap, double check it for leaks. If it looks okay, then the problem may be more serious. A bad radiator cap can cause coolant to slowly leak out...

The vehicle may need to have it's computer reprogrammed to improve the shifting performance of your transmission. The manufacturer has a technical bulletin available to reprogram the system correctly for your particular vehicle. It all depends on what exactly is...

An engine failure is definitely not good news. Engine failures can be caused by numerous things (e.g. low oil pressure, contaminants in the intake, etc.). Thankfully the 2007 Optima is covered by Kia’s 10 year, 100,000 mile power train warranty....

Hi there. Most of the time, the issue you're describing is caused by a malfunction inside the windshield wiper motor. Sometimes it's caused by the wiper arm being stripped on the motor strut itself. The best way to correctly diagnose...

From what you've described, you may have a bad crankshaft sensor. You'll know if this is the case once you run a scan test to get sensor data. The sensor may not be sending a crankshaft signal to the computer....

Hi. If the engine will turn over and try to start, then it may be a problem with fuel pressure or one of the engine sensors. It is common for the fuel pump to fail as well as the crank...

If the AC is only blowing hot air then most of the time it is because the AC compressor is not turning on. The compressor will not turn on for a number of reasons, but the most common is low...

This may be likely related to a fuel pump issue or lack of fuel pressure. Low fuel pressure is something that can cause your car to struggle to idle or even stall when driving. This will also cause the Check...

Hello. Most of the time when this car suddenly stops like this it is because the timing belt broke. If it has never been replaced then this is very likely. It can also occur if the ASD relay failed or...

This problem is not a common problem on these vehicles and the problem may be a major transmission pan leak and fluid got too low to engage the transmission. If the linkage is disconnected from a broken shift cable would...

Hello. If the coolant is leaking that fast then you should be able to see the vehicle leaving a puddle on the ground. If it is leaking onto the ground then it can be from a number of places. If...

The freeze plugs were designed to pop out if your coolant froze to prevent damage to the motor. They do not come out from overheating. The leaking water from the freeze plug means that it rusted out from the inside....

There are a few variables to account for when a clutch goes out. The clutch itself needs to be checked to see if it's the only problem as well as the transmission. I recommend having the clutch system checked throughly...

Hi there. Check the Internal Control Pressure Sensor (ICP) and see if its not working properly. If the ICP is working fine, then it is possible that the inner lining in the fuel tank may have come apart and has...

It is possible that you may have a leak somewhere in the AC system. However it is normal that every few years your air conditioning refrigerant will need to be serviced, as the refrigerant is a gas and does slowly...
