If you own a 2015 Jeep Grand Cherokee Laredo, you might have already noticed some quirks. The 2015 Jeep Grand Cherokee Laredo problems range from electrical glitches to transmission troubles, and knowing them early can save you money. This guide walks you through the most common issues, what to look for, and how to fix them.
The 2015 model year brought a lot of style and capability, but it also came with a few headaches. Owners often report problems that pop up after 50,000 miles. Some are minor annoyances, while others can leave you stranded. Let’s break it all down so you can stay ahead of the curve.
2015 Jeep Grand Cherokee Laredo Problems
Electrical system failures are the top complaint among owners. The infotainment screen may freeze, the power windows might stop working, or the dashboard lights can flicker for no reason. These issues often stem from a weak battery or a faulty TIPM (Totally Integrated Power Module).
Electrical System Glitches
The electrical system in the 2015 Laredo is complex and sensitive. Many drivers report the Uconnect system rebooting randomly. You might lose radio, navigation, or backup camera function without warning. In some cases, the battery drains overnight if the car sits unused.
- Check the battery terminals for corrosion first. Clean them with a wire brush.
- If the infotainment screen freezes, try a soft reset by holding the volume and tune buttons for 10 seconds.
- A failing TIPM can cause multiple electrical failures at once. Replacing it costs around $800 to $1,200.
Another common electrical issue is the keyless entry system. The doors might not lock or unlock with the remote. Sometimes the car won’t start even with the key fob inside. Replacing the fob battery is an easy first step, but if that doesn’t work, the receiver module may need replacement.
Transmission Hesitation And Shifting Problems
Many owners complain about rough shifting or hesitation when accelerating. The 8-speed automatic transmission in the 2015 Laredo can feel jerky, especially in stop-and-go traffic. Some drivers notice a delay when shifting from Park to Drive.
- First, check the transmission fluid level. Low fluid can cause harsh shifts.
- If the fluid looks dark or smells burnt, a flush and refill might help.
- Software updates from the dealer can improve shift quality. Ask about TSB 21-003-14.
- In severe cases, the valve body may need replacement. This costs $1,500 to $2,500.
The transmission problem often gets worse over time. Ignoring it can lead to complete failure. If you feel a hard thud when shifting gears, get it checked immediately.
Air Suspension Failures
If your Laredo has the optional air suspension, be prepared for leaks. The system uses air bags instead of traditional springs, and they can develop cracks. A common sign is the car sitting lower on one side after being parked overnight.
- Listen for the air compressor running constantly. It should cycle on and off.
- Check for hissing sounds near the wheels. That indicates an air leak.
- Replacing a single air strut costs $800 to $1,200. The compressor adds another $600.
- Some owners switch to a conventional coil spring conversion to avoid future issues. That costs around $1,500.
The air suspension warning light often comes on without warning. You can still drive the car, but the ride quality will suffer. If the compressor fails completely, the car will sag to the ground and be undrivable.
Engine Oil Consumption
The 3.6-liter V6 engine in the 2015 Laredo is known for burning oil. Some owners report adding a quart every 1,000 miles. This can lead to spark plug fouling and catalytic converter damage if ignored.
- Check the oil level every time you fill up with gas. Keep a quart in the trunk.
- Use the recommended 5W-20 full synthetic oil. Cheap oil can worsen consumption.
- If consumption exceeds 1 quart per 1,000 miles, the piston rings may be worn. Rebuilding the engine costs $3,000 to $5,000.
- A PCV valve replacement is a cheap fix that sometimes helps. It costs under $50.
Oil consumption problems often start around 60,000 miles. Catching it early can prevent major engine damage. Watch for blue smoke from the exhaust, which indicates burning oil.
Cooling System Leaks
The cooling system in the 2015 Grand Cherokee Laredo can develop leaks at the water pump or radiator. Overheating is a serious risk if you ignore small drips. The plastic radiator tanks are prone to cracking over time.
- Check the coolant level monthly. Low coolant can cause the engine to run hot.
- Look for white or pink residue around the water pump. That indicates a leak.
- Replacing the water pump costs $400 to $600. The radiator replacement is $500 to $800.
- Use only Mopar-approved coolant. Mixing types can cause gelling and blockages.
If the temperature gauge climbs above normal, pull over immediately. Driving an overheated engine can warp the cylinder heads, leading to a $4,000 repair bill.
Steering And Suspension Noises
Many owners report clunking or popping sounds from the front suspension. This is often caused by worn ball joints or tie rod ends. The noise is most noticeable when turning at low speeds or going over bumps.
- Jack up the front of the car and wiggle the wheels. Any play indicates worn parts.
- Replace ball joints and tie rods in pairs. A full front end rebuild costs $800 to $1,200.
- If the steering feels loose, the steering rack may have internal wear. Replacement costs $1,000 to $1,500.
- After repairs, get a professional alignment. Bad alignment wears tires quickly.
Ignoring suspension noises can lead to uneven tire wear and poor handling. The problem usually gets louder over time, so address it early.
Brake System Issues
Premature brake wear is a common complaint. The front brake pads on the 2015 Laredo can wear out in as little as 20,000 miles. Some owners also report warped rotors that cause steering wheel vibration when braking.
- Inspect brake pads every oil change. Look for thickness below 3mm.
- If the steering wheel shakes when braking, the rotors are likely warped. Resurfacing or replacing them costs $300 to $500 per axle.
- Use ceramic brake pads for longer life. They produce less dust and last longer than semi-metallic pads.
- Check brake fluid condition. Dark or contaminated fluid can cause spongy pedal feel.
Brake problems can escalate quickly. If you hear grinding noises, the pads are completely worn and metal is contacting the rotor. That requires immediate replacement.
Heating And Air Conditioning Failures
The HVAC system in the 2015 Laredo can act up. Some owners report the air conditioning blowing warm air on one side while cold on the other. This is often caused by a blend door actuator failure.
- Listen for clicking sounds behind the dashboard. That indicates a faulty actuator.
- Replacing a blend door actuator costs $200 to $400, depending on location.
- If the A/C blows warm air everywhere, the refrigerant may be low. A recharge costs $100 to $200.
- Check the cabin air filter. A clogged filter reduces airflow and cooling performance.
Heater problems are also common. If the heater blows cold air, the coolant level may be low or the heater core could be clogged. Flushing the heater core sometimes fixes the issue.
Door Lock Actuator Failures
Power door locks can fail on the 2015 Laredo. The actuator inside the door stops working, leaving the door unable to lock or unlock with the switch or remote. This usually affects one door at a time.
- If the door lock makes a buzzing sound but doesn’t move, the actuator is dead.
- Replacing a door lock actuator costs $150 to $300 per door.
- You can still lock the door manually using the key, but it’s inconvenient.
- Some owners replace all four actuators at once to avoid repeated trips to the shop.
Door lock failures are more common in cold climates. Moisture can freeze the mechanism, causing premature wear.
Fuel System Problems
Some owners experience hard starting or rough idling. This can be caused by a failing fuel pump or clogged fuel injectors. The 2015 Laredo’s fuel system is sensitive to dirty fuel.
- If the engine cranks but doesn’t start, check the fuel pump fuse first.
- A failing fuel pump may whine loudly before it dies. Replacement costs $600 to $900.
- Use a fuel system cleaner every 5,000 miles to keep injectors clean.
- If the check engine light comes on with a lean code, the fuel pressure regulator may be faulty.
Fuel system issues can leave you stranded. If the car stalls while driving, the fuel pump is likely failing. Replace it before it fails completely.
