2017 chevrolet traverse reliability: What Owners Really Need to Know
The 2017 model year is generally considered the “sweet spot” for the first-generation Traverse because Chevrolet had nearly a decade to iron out the kinks. However, no vehicle is perfect, and this SUV carries some specific traits that require your attention to ensure 2017 chevrolet traverse reliability remains high. Being proactive is much cheaper than being reactive when it comes to a large crossover.
Most owners report a positive experience, but the key to success lies in understanding the 3.6L LFX V6 engine. This engine is a workhorse, but it is sensitive to oil quality and cooling efficiency. If you follow the factory service intervals strictly, you are already ahead of the curve, but “enthusiast-level” maintenance goes a step further.
When evaluating the 2017 Chevrolet Traverse specifications, you see a vehicle designed for utility. To keep that utility intact, you must focus on the drivetrain and the various sensors that manage performance. Let’s break down the major components that define the ownership experience.
Understanding the 3.6L LFX V6 Engine and Timing Chain Health
The heart of the 2017 Traverse is the 3.6L LFX V6 engine, which features direct injection for better power and efficiency. While powerful, this engine design is known for creating internal heat and placing stress on the timing chain tensioner. If the oil level drops or the oil becomes dirty, the tensioners can lose pressure, leading to chain stretch.
One of the most dreaded sights for an owner is the Check Engine Light accompanied by code P0008 engine position system performance. This often indicates that the timing chains have stretched beyond the computer’s ability to compensate. To prevent this, never skip an oil change and always check your dipstick every few weeks.
The Importance of Dexos1 Gen 2 Motor Oil
Using the correct oil is not just a suggestion for this engine; it is a requirement for survival. You should always use Dexos1 Gen 2 motor oil, which is specifically formulated to handle the high heat of direct-injection engines. This oil helps prevent “low-speed pre-ignition” and keeps the small oil passages in the Variable Valve Timing solenoid clear of sludge.
I recommend changing your oil every 5,000 miles rather than waiting for the vehicle’s oil life monitor to hit zero. This shorter interval ensures that the timing chain and tensioners are always lubricated with fresh, high-viscosity fluid. It is a small price to pay to avoid a multi-thousand-dollar engine teardown later.
Addressing Direct Injection Carbon Buildup
Because the LFX engine uses direct injection, fuel is sprayed directly into the cylinder rather than over the intake valves. This means the valves aren’t “washed” by gasoline, leading to direct injection carbon cleaning needs over time. Every 30,000 miles, consider using a specialized intake valve cleaner to keep the airflow smooth and the idle steady.
Maximizing the 6T75 Automatic Transmission Life
The 6T75 automatic transmission in the 2017 Traverse is generally robust, but it works hard to move such a heavy vehicle. Heat is the primary enemy of any automatic gearbox, especially if you use your SUV for towing. Ensuring the fluid remains clean and cool is the best way to protect your investment.
If you notice “searching” for gears or a slight shudder during shifts, do not ignore it. These are often early warning signs that the fluid is breaking down or the solenoids are struggling. A simple fluid exchange (not a high-pressure flush) can often restore shift quality and extend the life of the internal clutches.
Fluid Service Intervals for Longevity
The manual might suggest long intervals for transmission service, but experienced DIYers know better. Change the transmission fluid every 45,000 to 60,000 miles to keep the 6T75 automatic transmission happy. Fresh fluid carries away heat more effectively and keeps the seals from hardening over time.
Always use the specific fluid recommended in your owner’s manual. Mixing fluids or using “universal” brands can lead to unpredictable shifting behavior. If you frequently haul heavy loads, consider installing an auxiliary transmission cooler to keep temperatures in the safe zone during summer trips.
Common Sensor Failures and Electrical Troubleshooting
Modern SUVs like the Traverse rely heavily on a network of sensors to keep everything running smoothly. While the mechanical components are solid, the 2017 chevrolet traverse reliability can sometimes be hampered by small electrical issues. Knowing which sensors are likely to fail can save you hours of diagnostic frustration.
One common culprit is the EVAP purge solenoid, which can cause difficulty starting after refueling. If your Traverse stumbles or refuses to fire up immediately after you fill the tank, this $30 part is likely the problem. It is an easy DIY fix that requires only basic hand tools and about fifteen minutes of your time.
StabiliTrak and Steering Angle Issues
If you see a “Service StabiliTrak” message on your dash, the most common cause is a failing StabiliTrak steering angle sensor. This sensor tells the computer which way you are pointing the wheels. When it fails, the traction control system gets confused and may disable itself for safety.
Before replacing expensive parts, always check the condition of your battery and the ground wires. A weak battery can cause “ghost” codes in the StabiliTrak system that disappear once the voltage is stabilized. Clean the battery terminals with a wire brush and ensure they are tight to maintain a solid electrical connection.
Suspension and Chassis: Handling the Weight
The Traverse is a large, heavy vehicle, and that weight takes a toll on the suspension over time. To maintain the smooth ride quality you expect, you need to keep an eye on the struts, bushings, and wheel bearings. A quiet cabin is a hallmark of a well-maintained Chevrolet Traverse full size SUV.
Listen for “clunking” sounds when driving over speed bumps or “humming” noises that change with vehicle speed. Clunks usually point to worn sway bar links or strut mounts, while humming often indicates a failing wheel bearing. Replacing these parts early prevents uneven tire wear and keeps the steering crisp.
Braking System Maintenance
Stopping a 5,000-pound SUV requires a lot of friction and heat. Check your brake pads and rotors every time you rotate your tires. If you feel a vibration in the steering wheel while braking, your rotors may be warped from excessive heat. Using high-quality ceramic pads can reduce dust and provide more consistent stopping power.
Don’t forget the brake fluid. Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This moisture can corrode internal components and lower the boiling point of the fluid. Bleed your brakes and replace the fluid every two to three years to keep the pedal feeling firm and responsive.
Diagnostic Symptom-to-Fix Table
Use this table to quickly identify common issues and the likely components involved. This is a great starting point for any DIY diagnostic session.
| Symptom | Likely Cause | Recommended Action |
|---|---|---|
| Hard start after refueling | EVAP purge solenoid | Replace solenoid (located on top of engine). |
| Check Engine Light (Code P0008) | Stretched timing chain | Inspect timing chain tensioner; likely requires chain replacement. |
| “Service StabiliTrak” message | StabiliTrak steering angle sensor | Scan for codes; replace sensor or check battery voltage. |
| Rough idle / Poor MPG | Carbon buildup on valves | Perform direct injection carbon cleaning service. |
| Coolant smell / Low level | Water pump leak | Pressure test system; replace water pump if leaking. |
Essential Cooling System Care
The 2017 Traverse uses Dex-Cool antifreeze, which is designed for long-life performance but can become problematic if mixed with other types. Always ensure your cooling system is topped off with the correct 50/50 mix of Dex-Cool and distilled water. If the coolant looks muddy or brown, it is time for a flush.
The water pump on the 3.6L engine is a known wear item. It is tucked away on the side of the engine and can be difficult to see. Look for “weep” marks or dried orange crust around the passenger side of the engine bay. Catching a water pump leak early prevents an overheat scenario that could warp the cylinder heads.
If you are working on the interior or upgrading your Traverse interior maintenance, take a moment to check the rear HVAC lines. In some climates, the aluminum lines running to the rear AC unit can corrode. If you notice the AC isn’t as cold as it used to be, have a shop check these lines for tiny pinhole leaks.
