Hello there, this is an extremely rare circumstance. In my research I have found several claims from various manufactures with spontaneous glass breaking from either the windows or sunroof. This can happen for a variety of reason from cracks to...

Hi There, This may be a result of low transmission fluid or potentially a faulty transmission control module. A faulty transmission control module may cause a delay in acceleration or erratic shifting of gears. The transmission control module has various...

Hey there. As you know, your car is equipped with wheel speed sensors at each of the four wheels which monitor wheel speed while relaying this information constantly to the ABS system which is controlled by the car's ECU. When...

Check the wiring harness from the gauge cluster to the speedometer and see if the gauge is working. If the gauge is not working, then the gauge cluster would need replaced. If the gauge is working, then there could be...

I believe that the towing company is correct. Heavy duty trucks get their power brakes hydraulically instead of a vacuum booster like passenger cars. Heavy duty trucks actually get their assist from the power steering pump fluid. So, if your...

It sounds as though you may have a brake hose that has collapsed inside. There are three flexible hydraulic hoses on your car that allow the brake lines to move with the wheels. There are two on the front and...

Hello - quite likely, the inconsistency with your gauge operation and the occasional dead battery are related, with a short in the wiring perhaps. This problem can be diagnosed by connecting an ammeter to the positive (red) battery cable, observe...

Hey there. There are some obvious possibilities: the fan or blower noise due to motor defect; the A/C clutch is chattering or slipping, and/or the clutch bearing is worn, loose, or wobbly; the compressor has an internal mechanical fault or...

Your car’s tire pressure monitoring system (TPMS) is designed to alert you when a tire’s pressure drops below a specific threshold. However, it might not mean that you have a flat. Here are a few things you need to know...

It sounds like you may have an over fueling situation going on where the motor is being provided more fuel than it can efficiently burn, resulting in the raw fuel smell you describe. This can happen for many different reasons...

Hello - shock absorber noises, both front and rear, is a fairly common complaint among Jeep owners, and for a few years now. Whether it is "normal" or acceptable is a subjective question, but if there is any fluid leaking...

It sounds like you may have a blown head gasket causing coolant to get into the engine cylinders. You will need to have the cooling system pressure tested and compression test done to verify the blown head gasket and need...

Hi there. The problem you're describing is typically caused by one of two things. First, is a fuel flow issue. When the vehicle is placed into drive it creates a load on the engine. To ensure that the engine continues...

Hello - both the overheating and the lack of heat out of the heater could be caused by inadequate bleeding of the cooling system when you put coolant in the car. To get all the air out of the system...

Changing spark plugs at 46000 isn't necessarily a bad idea, but mostly I say that because it will keep them from seizing to the cylinder head. Most late model cars like yours can run a set of plugs for longer...

Hi there. Today's modern cars, trucks and SUV's are much more complex than older vehicles. As such, there really isn't a general "tune-up" service. Instead, manufacturers have created recommended maintenance service, which is unique for each make, model and year....

Intermittent low fuel pressure could cause the problem you are describing, perhaps aggravated by a restricted fuel filter, however, stalling is also commonly due to faults in the ignition switch, hall effect sensors, idle speed control (ISC) system, loss of...

Hi JagJoe. Thanks for writing in to YourMechanic.com. Unfortunately, replacing engines is not a service we offer - or within our scope of repairs. I would recommend searching on Google for a local engine replacement shop or service shop that...

Hello, thank you for writing in. Code P0449 will set when the system sees that the position of the vent valve, and the voltage for its position, do not match. There could be a wiring problem, a faulty hose, or...

Hi there. Unfortunately, once there is oil and coolant mixed, there is the possibility of a cracked cylinder head/block or a blown cylinder head gasket. This is a serious condition as the internal damage generally snowballs into worse; the main...

Hello, thanks for writing in. I will try to help you with this. If the car has no other significant repair needs (i.e., costs), the calculation is fairly straightforward. If other repairs are required it is much more complicated. So,...
