Inevitably, your Subaru will see a time when it is no longer working like it was when it was new. If regular maintenance isn’t enough to fix it, diagnostics may be needed.
Any warning lights that do not turn off after starting your engine are an indication of trouble in one of your vehicle’s systems. If the warning light is yellow or green, a diagnostic should be scheduled at your earliest convenience. If the warning light is red or if your “Check Engine” light is blinking, we recommend that you stop driving the vehicle and have it towed in to avoid damaging additional components.
Below are lights that should not be on or blinking without activation:
- Check Engine
- Oil level
- Oil pressure
- Cruise Control
- AT Temp
- Trac Off
- Traction Control
- Tire pressure (TPMS)
- Air Bag
If your engine is not operating as it should, we can help you figure out why. Our state-of-the-art diagnostic tools and techniques help us pinpoint the cause of your engine trouble so we can accurately estimate the repairs you need.
Our engine diagnostics include:
- Engine performance and drivability
- Abnormal engine noises
- Oil consumption
- Compression and leak-down testing
- Volumetric efficiency
Your cooling system is one of the most important systems on your Subaru. When cooling system problems are overlooked, engine damage can occur.
We can diagnose following cooling system concerns:
- Coolant leaks
- Coolant consumption
- Coolant contamination
- Radiator fan operation
Electrical and Accessories
Malfunctioning electronics, short circuits, starting and charging system problems, and parasitic loads.
Here are some areas that we can help diagnose:
- Power windows, locks, mirrors, and seats
- Heated seats
- Sunroofs / moonroofs
- Electric parking brakes
- Cruise control
Starting and Charging
If your Subaru has trouble starting, it can’t do you much good! At the first signs of trouble, diagnostics are highly recommended to ensure reliable starting.
Symptoms of a failing starting and/or charging system (especially in cold weather) can include:
- Slow starting
- No starting
- Battery failures
- Charging trouble
- Parasitic loads that drain your battery
Transmission, Differential, and Drivetrain
These systems cover everything between your engine and wheels, and are comprised of your transmission, transfer case, clutch, driveshaft, differentials, axles, wheel bearings, and hubs.
Symptoms of a malfunctioning drivetrain may include:
- “AT Temp” light on or flashing
- Binding/shuddering when turning
- Groaning, whining, or clicking noises
- Delayed or harsh shifting
