You’ve got a 2017 Grand Cherokee, but that check engine light just won’t stay off. It’s a common frustration for owners dealing with Jeep Grand Cherokee Issues 2017 models. This guide walks you through the most frequent problems, how to spot them early, and what you can do to fix them without breaking the bank.
The 2017 Grand Cherokee is a capable SUV, but it has its share of quirks. Some issues are minor annoyances, while others can leave you stranded. Let’s break down what you need to know.
Common Electrical Problems
Electrical gremlins are a top complaint for 2017 Grand Cherokee owners. The most common issue involves the battery and the TIPM (Totally Integrated Power Module).
Battery Drain And Dead Battery
Many owners report finding a dead battery after the car sat for just a day or two. This isn’t always a bad battery. Often, a module stays awake and drains power.
- Check for interior lights staying on
- Ensure the radio turns off when you exit
- Test the battery voltage with a multimeter (should be 12.6V when off)
If the battery drains overnight, the TIPM might be the culprit. A failing TIPM can cause parasitic draw that kills the battery.
Uconnect Screen Freezing Or Going Black
The Uconnect system in the 2017 model can freeze, reboot randomly, or go completely black. This is annoying because you lose climate control and radio.
- Try a soft reset: hold the volume and tuner knobs for 10 seconds
- If that fails, disconnect the battery for 30 minutes
- Check for software updates at your dealer
Some owners have had to replace the entire radio unit. That’s expensive, so try the reset first.
Power Window And Lock Failures
Windows may stop working or roll down slowly. Door locks might click but not engage. This is often a faulty window regulator or lock actuator.
- Listen for a clicking sound when you press the switch
- If you hear nothing, the motor might be dead
- If you hear clicking but no movement, the regulator is stuck
Replacing a window regulator is a DIY job if you’re handy. The part costs around $50-80.
Engine And Transmission Concerns
Under the hood, the 2017 Grand Cherokee has some known weaknesses. The V6 engine is generally reliable, but the V8 and diesel have specific issues.
Engine Tick Or Knock Noise
A ticking noise from the engine is common, especially on the 3.6L Pentastar V6. This can be normal injector noise, but it can also signal a problem.
- Check the oil level first. Low oil causes ticking
- Listen for a rhythmic tick that speeds up with RPM
- If the noise is loud, it could be a failing rocker arm or lifter
Some owners have had to replace the entire cylinder head due to worn valve guides. This is a costly repair, so catch it early.
Transmission Hesitation Or Harsh Shifting
The 8-speed automatic transmission can feel hesitant or jerk when shifting. This is often a software issue, not a mechanical failure.
- Try a transmission reset: turn key to ON, press gas pedal to floor for 10 seconds, then turn key OFF
- Check for TSBs (Technical Service Bulletins) for your VIN
- Have the dealer update the transmission control module software
If the problem persists, the valve body might need replacement. That’s a $1500-2000 job.
Oil Filter Housing Leak
The plastic oil filter housing on the 3.6L engine is prone to cracking. This causes a major oil leak that can empty your engine quickly.
- Look for oil pooling around the oil filter
- Check for oil dripping onto the exhaust manifold
- If you smell burning oil, stop driving immediately
Replace the plastic housing with an aluminum aftermarket part. It costs about $100 and prevents future failures.
Suspension And Steering Issues
The ride quality can degrade over time. The air suspension system on higher trims is especially problematic.
Air Suspension Compressor Failure
If your Grand Cherokee has air suspension, the compressor often fails around 60,000 miles. You’ll see a “Service Air Suspension” message.
- The rear of the car sags when parked
- The compressor runs constantly but never stops
- You hear a loud buzzing from the front passenger side
Replacing the compressor costs $800-1200. Some owners convert to traditional coil springs for $1500-2000.
Front End Clunking Noise
A clunk or pop when turning or going over bumps is common. This is usually worn sway bar links or control arm bushings.
- Jack up the front and shake the wheel side to side
- If there’s play, the tie rod ends or ball joints are worn
- Listen for a clunk when you rock the car
Sway bar links are cheap ($20-40 each) and easy to replace. Control arms are more involved.
Steering Wheel Vibration
A vibration in the steering wheel at highway speeds can be from unbalanced tires, but it’s often a warped brake rotor or a failing steering rack.
- If vibration happens only when braking, it’s rotors
- If vibration is constant, check tire balance
- If vibration changes with road surface, suspect steering rack
Warped rotors are common on the 2017 model. Replace them with high-quality aftermarket rotors.
Cooling System Problems
Overheating is a serious issue for the 2017 Grand Cherokee. The cooling system has several weak points.
Water Pump Failure
The water pump on the 3.6L engine can fail early. You might see coolant leaking from the front of the engine.
- Check for a puddle of green or orange coolant under the car
- Look for coolant residue on the water pump pulley
- Listen for a whining noise from the front of the engine
Replace the water pump and thermostat together. The parts cost around $150-200.
Radiator Leaks
The plastic end tanks on the radiator can crack. This causes coolant loss and overheating.
- Inspect the radiator for cracks near the hose connections
- Check for white or pink crusty residue
- If the temperature gauge climbs, pull over immediately
Replacing the radiator is a DIY job. The part costs $100-150.
Coolant Temperature Sensor Failure
A bad coolant temperature sensor can cause the check engine light to come on. It might also make the cooling fan run constantly.
- Scan for codes like P0118 or P0128
- Check the sensor connector for corrosion
- Replace the sensor if the reading is erratic
The sensor costs about $20 and is easy to replace.
Interior And Comfort Complaints
Inside the cabin, there are several annoyances that owners report frequently.
Seat Heater Malfunction
The seat heaters can stop working or get stuck on high. This is often a broken heating element inside the seat.
- If the heater works intermittently, the element is cracked
- If it doesn’t work at all, check the fuse first
- Replacing the element requires removing the seat cover
Some owners have had the seat cushion replaced under warranty.
Sunroof Leaks Or Rattles
The panoramic sunroof can leak water into the cabin. It can also rattle when open or closed.
- Clean the drain tubes with compressed air
- Check the rubber seal for tears
- Lubricate the tracks with silicone grease
If the leak is bad, the headliner might get stained. Fix the drain tubes before it gets worse.
Dashboard Cracking
Some owners report the dashboard cracking near the defroster vents. This is a cosmetic issue but annoying.
- Use a sunshade to protect the dash from UV rays
- Apply a UV protectant regularly
- If cracked, a dash cover can hide the damage
Replacing the dashboard is expensive and labor-intensive.
Brake System Issues
The brakes on the 2017 Grand Cherokee can wear unevenly or make noise.
Premature Brake Pad Wear
Front brake pads often wear out before 30,000 miles. This is due to the heavy weight of the SUV.
- Check pad thickness through the wheel spokes
- Listen for a squealing noise when braking
- If you feel pulsation, the rotors are warped
Upgrade to ceramic pads for longer life. They cost a bit more but last longer.
Brake Pedal Goes To Floor
A soft brake pedal can indicate air in the system or a failing master cylinder.
- Check the brake fluid level in the reservoir
- Look for leaks at the calipers or lines
- If the pedal sinks slowly, the master cylinder is failing
Bleeding the brakes might fix a soft pedal. If not, replace the master cylinder.
Parking Brake Failure
The electronic parking brake can fail to engage or release. This leaves you stuck or unable to park.
- Try engaging and disengaging the brake several times
- Check the brake module for error codes
- If the motor is dead, the caliper needs replacement
This is a safety issue. Get it fixed promptly.
Fuel System Problems
Fuel-related issues can cause poor performance and check engine lights.
Fuel Pump Relay Failure
The fuel pump relay can fail, causing the engine to crank but not start.
- Listen for the fuel pump humming when you turn the key to ON
- If you don’t hear it, check the relay in the fuse box
- Swap the relay with a similar one to test
Replacing the relay costs $10-20.
Evap System Leak
A loose gas cap is the most common cause of an evap leak code (P0456). But it can also be a cracked hose.
- Tighten the gas cap until it clicks
- Clear the code and see if it returns
- If it does, inspect the evap hoses for cracks
A smoke test at a shop can find the exact leak location.
Rough Idle Or Stalling
A rough idle can be from a dirty throttle body or a failing idle air control valve.
- Clean the throttle body with throttle body cleaner
- Check for vacuum leaks in the intake hoses
- If the idle surges, the IAC valve might be bad
Cleaning the throttle body often fixes rough idle.
