GMC Repairs
All vehicles need repairs at one time or another and GMCs are no exception. Due to extreme temperature fluctuations hoses, gaskets and belts will deteriorate. Items such as the clutch, brakes and tires experience wear and tear over time. Keeping up with these repairs can help save you time and money in the long run. Some of the most common repairs our technicians see are:

Power Windows & Door Locks
If you notice your power windows are starting to stick or roll up or down slower than they used to, it could be a failing power window regulator. Having problems with locking or unlocking your doors? Your door lock actuator(s) may need to be replaced. If you are experiencing problems with your power windows or door locks, schedule an appointment with your Pickerings’ ASE Certified expert technician.

Water Pump
The cooling system in your GMC vehicle can develop a leak or the water pump can wear out and fail. A faulty or leaky water pump is a serious problem since a lack of coolant will result in an overheating engine. Some symptoms include high temperature readings, steam coming from underneath the hood, or a puddle of coolant under your vehicle. If you notice any of these warning signs, bring your GMC in for a full vehicle health inspection. We’ll make any necessary repairs and get you back on the road safely.
 
Common Oil Leaks

Valve Cover Leaks
In order to keep the oil in your engine where it belongs, your GMC engine is sealed with a valve cover and gasket. The valve cover gaskets are made of rubber or plastic and will deteriorate over time, allowing oil to leak out. Even a small oil leak can cause major damage to your engine so be sure to have your oil serviced on a regular basis with a Pickering’s ASE Certified technician. They will be able to spot leaks in your valve cover and replace it before more serious damage occurs.

Oil Pans
Don’t ignore a puddle of oil under your vehicle! Even small oil leaks can cause major damage if not repaired. The gasket that seals the oil pan to your engine can become brittle and cracked, allowing oil to leak out. If your engine lacks proper lubrication it will eventually fail and you could end up stranded at the side of the road. If your engine warning light comes on or you smell burning oil, bring your GMC to Pickering’s right away for a diagnosis.

Rear Main Seal
It’s dangerous to drive your GMC with a leaking rear main seal as it can deplete your engine of oil very quickly and cause serious damage to your motor. Unfortunately, it’s also a laborious and time-intensive repair due to its location. Depending on your make of vehicle, either the engine or the transmission will need to be removed in order to replace the seal. If you suspect your GMC has a leaking rear main seal, have it inspected right away by a Pickering’s ASE Certified technician.

Air Suspension & Electrical/Magnetic Ride Control Suspension
Rear end air suspension systems like those commonly found on the GMC Envoy can have issues and can be expensive to replace. The air bags themselves will sometimes leak or the compressor that supplies the air can go out. A common sign of air suspension issues is a lower ride height. Clicking, grinding or whining sounds could signal a problem with the compressor fan. In some cases, standard struts/shocks can be used to replace the air or electrical/magnetic ride control shocks as a more affordable repair. Consult a Pickering’s ASE Certified technician to find out the best option for your GMC.

Air Intake Leaks
The intake manifold gaskets seal the engine creating a vacuum. If you have a leak, you may notice performance issues with your GMC such as misfires, lower fuel efficiency or a decrease in power and acceleration. If you notice a coolant leak or your engine is overheating, bring it to Pickering’s Auto Service right away for an inspection with one of our ASE certified technicians before more serious and costly engine damage can occur.

Steering and Suspension Components
Issues with the steering and suspension components are not uncommon, especially in GMC SUVs and trucks. The following parts are prone to failure:

Ball Joints
If you notice clunking noises or excessive vibration coming from the front suspension, you may have failing ball joints. Another sign is if your vehicle drifts to the right or left on its own. Since the ball joints are an important part of your GMC’s handing, you’ll want to have it inspected by one of our ASE certified technicians. They’ll help you determine the best course of action and make any needed repairs to get you safely back on the road.

Tie Rods
The tie rods on your GMC can wear our and will typically display a few warning signs when they are going bad. If your vehicle is drifting to the right or left, it’s a sign that the alignment is off. This will result in uneven wear on your tires, which is another symptom of a bad tie rod. You may also notice your steering wheel shakes or feels loose. If you become aware of any of these symptoms, bring your GMC to Pickering’s Auto Service for proper diagnosis and repairs.

Sway Bar links
When stabilizer bars, or sway bar links begin to wear out, you’ll hear clunking or scratching noises coming from the front wheels. Your steering wheel may start to feel loose or you may notice more body sway. If you notice any of these issues, bring your GMC to Pickering’s Auto Service right away to have it inspected.

Ignition Components

  • Ignition Coils: If you engine is misfiring, it could by caused by bad ignition coils. If not replaced, it will quickly lead to performance issues such as reduced gas mileage and loss in power and acceleration.
  • Key/Ignition Switch: If your ignition switch is faulty, you might have trouble starting the engine. Your GMC vehicle may start up and immediately stall or it may not start at all, leaving you stranded or at the very least, late for work.
  • Lock Cylinders: If you have trouble inserting and removing the key, or starting the engine, it could be the ignition lock cylinder is worn out. If you experience problems with any of your ignition components, bring your GMC to Pickering’s Auto Service as soon as possible.
