The key in your vehicle will not turn due to the dead battery. This is because you have an electronic ignition lock that no longer has the required voltage to allow the key to turn. You can jump start the vehicle,...
Hey there. The Check Engine Light can set if the catalyst efficiency is below threshold. There will be no visible symptoms at all, or change in engine performance, because the recorded "low efficiency" can simply mean that more pollutants are...
There are 3 items in the xenon light circuit responsible for igniting the bulb. According to Infiniti's TSB on xenon light, they recommend replacing the bulb first, and that will solve most problems. The HID control unit, and the...
What you are describing does sound like a bad inner C/V joint or joints. Even if the C/V boot is not torn and all the grease thrown out like typically happens with outer C/V boots, inner C/V boots can get...
Hi there. If your vehicle feels like this while you drive then you either have worn out suspension struts or you may have a loose suspension part. A mechanic would typically start by checking to see if there are any...
On some of these engines, the idler, or tensioner pulley, tends to go bad and throws the belt. However, it could be that your belt just broke from age and wear, or another problem caused the belt to break or...
The a/c fan may be the cause on this vehicle or the controller for the fan. A check to see if the fan motor is getting proper power from the module is the first test needed. I recommend having a...
You may have a belt tensioner not suppling enough tension on the belt. The power steering may also be low on fluid. The belt may be loose which will need to be adjusted tighter. The idle problem may be due...
There are a couple of possible issues. Looking at Ford's technical service bulletins, possible issues range from water intrusion in a sensor to a possible warped separator plate between the valve body and transmission case to possible internal wear in...
Hello. It sounds like the window motor failed. It is much easier for a failing motor to lower and window and not be able to close it. I would typically remove the door panel and first check the voltage at...
Hello. This is probably your front undertray panel, which is usually held in place with quick turn plastic screws. Probably during your last oil change or maintenance, the technician did not get those quick turn screws installed correctly, so they...
Unfortunately without more information it will be difficult to narrow down why you are experiencing a knocking sound in your vehicle. In my experience Envoys have had many different reasons that could duplicate an engine knock. The most common is...
Hi Patel. Thanks for contacting us tonight. While synthetic oils are typically longer lasting than a conventional oil, the engine and ECU can't predict or detect the oil in the engine. This is why the warning light illuminates. I still...
Hello. This could be caused by a variety of things. It could be that your spark plugs or coil packs are misfiring. This means that the coil pack is not sending the proper electricity to the spark plug. It could...
Hello. I would have this issue addressed immediately since an overheating engine can cause a lot of permanent damage. A cooling system pressure test would need to be done to determine where your leak is coming from. From there, a...
There is a TSB for a possible crack that can form in the right side exhaust tube, and cause a noise characteristic similar to what you are describing. The pipe will have to repaired, or replaced, based on the damage...
Hi. You are fortunate that the latch is accessible. You can get under the front of your car and look up just behind the bumper. You will see the bottom of the hood latch, and the operating cable going into...
Hello. This is a common issue on this vehicle. If the transmission does not appear to be slipping then you either have a failing driveline coupler or a bad transmission mount. Over time both of these can rot out and...
This is not a common problem. The engine may have been starved of oil and the only way to tell is to do an oil sample to see what failed inside the engine unless a rod is sticking through the...
I recommend that you have a mechanic, like one from YourMechanic, check your vehicle out for you. The mechanic can pressure test the cooling system, and replace any leaking hoses.
Hi there. There are many things that can produce a tapping noise when idling. It’s not always the engine internals, but usually. There have been cases of your serpentine belt tensioner making a tapping noise. Check your oil level and...
Sounds like you might have a large vacuum leak. Think of your engine as a big vacuum cleaner. If the vacuum cleaner has a restriction then it slows down, if the port is completely open it goes as fast as...
If you are referring to the first few minutes of driving when the engine is cold, the engine coolant temperature sensor must be working properly to signal the PCM to enrich the mixture on cold start. If there is a...
Hello. From the symptoms you describe, it would appear that the vehicle has some sort of issue with the cooling system. If the white smoke was coming from the tailpipe, the coolant has to be frequently replaced, and the there...
Hi there. The code that you are getting is for the output speed sensor of the transmission. I change quite a few of these as they are a common issue. I would have this replaced first and clear the codes....
