Common problems with the 2012 Jeep Grand Cherokee Laredo include a failing TIPM that causes the fuel pump to stop working unexpectedly. This issue is one of the most reported complaints by owners, and it can leave you stranded without warning. Other frequent concerns involve electrical gremlins, transmission troubles, and suspension noises that make daily driving frustrating.
If you own a 2012 Jeep Grand Cherokee Laredo or are thinking about buying one, you need to know what to watch for. This guide covers the most common problems, how to spot them early, and what you can do to fix them. Let’s get straight into the details.
2012 Jeep Grand Cherokee Laredo Problems
The 2012 model year brought a redesigned Grand Cherokee, but it also introduced several reliability headaches. Many owners report issues that range from minor annoyances to major safety concerns. Below, we break down the top problems by category.
Failing Totally Integrated Power Module (TIPM)
The TIPM is essentially the brain that controls electrical functions like the fuel pump, wipers, and power windows. In the 2012 Grand Cherokee Laredo, this module is prone to failure. Symptoms include the fuel pump cutting out, the engine stalling, or the car not starting at all.
Some owners have experienced the fuel pump stopping while driving at highway speeds. This is dangerous and can lead to accidents. The fix often involves replacing the TIPM, which can cost between $800 and $1,200 at a dealership.
- Fuel pump stops working without warning
- Engine stalls or refuses to start
- Power windows or door locks act erratically
- Wipers turn on by themselves or stop working
If you notice any of these signs, have the TIPM inspected immediately. Some owners have had success with aftermarket repairs, but a full replacement is usually the safest route.
Transmission Shifting Issues
Another common complaint involves the 8-speed automatic transmission. Owners report rough shifting, hesitation when accelerating, and delayed engagement when shifting from Park to Drive. These issues are often more noticeable in stop-and-go traffic.
The problem can stem from low transmission fluid, a faulty solenoid, or software glitches. In some cases, a simple software update from the dealer can smooth things out. But if the damage is mechanical, a rebuild or replacement might be necessary.
- Check transmission fluid level and condition
- Visit a dealer for a TCM software update
- If problems persist, have a transmission specialist diagnose it
Ignoring transmission issues can lead to complete failure, so address them early. A transmission rebuild for this vehicle can cost $3,000 or more.
Air Suspension Problems (If Equipped)
Some 2012 Grand Cherokee Laredo models came with an optional air suspension system. This system is known for compressor failures, air leaks, and uneven ride height. When it fails, the vehicle may sag on one corner or refuse to raise at all.
Replacing the air suspension components is expensive. A new compressor can cost over $1,000, and replacing all four air struts can run into the thousands. Many owners choose to convert to a conventional coil spring setup instead.
- Vehicle sits unevenly or sags overnight
- Compressor runs constantly or makes loud noises
- Warning lights on the dashboard for suspension
If you have air suspension, check for leaks regularly. A simple soapy water test on the air lines can reveal small holes. Converting to coils is a popular long-term fix.
Electrical Gremlins Beyond The TIPM
Even if the TIPM is working, other electrical problems can pop up. Owners report issues with the infotainment screen freezing, backup camera not working, and dashboard lights flickering. These problems can be intermittent and hard to diagnose.
Battery drain is another common issue. Some owners find their battery dead after the car sits for a few days. This can be caused by a parasitic draw from a module that doesn’t shut down properly.
To diagnose electrical issues, start with the battery and alternator. A simple voltage test can rule out basic problems. If those are fine, you may need a professional scan tool to find the draw.
Engine Problems: Hemi Tick And Oil Consumption
The 2012 Grand Cherokee Laredo came with a few engine options, including the 3.6L Pentastar V6 and the 5.7L Hemi V8. Both have known issues. The 3.6L is prone to oil cooler leaks and timing chain problems. The 5.7L often develops a “Hemi tick” caused by exhaust manifold bolts breaking.
Oil consumption is a concern with the 3.6L engine. Some owners report using a quart of oil every 1,000 miles. This can lead to engine damage if not monitored. Check your oil level regularly and top off as needed.
- Listen for ticking noises from the engine bay
- Watch for oil spots under the vehicle
- Monitor oil level between changes
If you hear a persistent tick, have the exhaust manifold inspected. Broken bolts are common and can be replaced, but the job is labor-intensive.
Cooling System Failures
Overheating is another problem reported by owners. The cooling system in the 2012 Grand Cherokee Laredo can fail due to a faulty water pump, a leaking radiator, or a stuck thermostat. Overheating can quickly lead to engine damage if ignored.
The water pump on the 3.6L engine is a known weak point. It often starts leaking before it fails completely. Replace it as soon as you see coolant on the ground or smell antifreeze.
- Check coolant level in the reservoir
- Inspect hoses and radiator for leaks
- Replace water pump if it shows signs of wear
Flushing the cooling system every 60,000 miles can help prevent buildup and extend the life of components.
Suspension And Steering Noises
Many owners complain about clunking or popping noises from the front suspension. This is often caused by worn ball joints, tie rod ends, or sway bar links. The 2012 Grand Cherokee Laredo is a heavy vehicle, and suspension components wear out faster than on lighter cars.
If you hear noises when going over bumps or turning, have the suspension inspected. Replacing worn parts early can prevent more expensive damage to other components.
- Clunking when driving over speed bumps
- Steering feels loose or vague
- Uneven tire wear
A front-end alignment and replacement of worn parts usually costs between $300 and $800, depending on what needs to be replaced.
Brake System Complaints
Some owners report premature brake wear and pulsation when braking. This can be caused by warped rotors or sticking calipers. The 2012 Grand Cherokee Laredo is heavy, so brakes work hard and can wear out faster than expected.
If you feel vibration through the brake pedal, have the rotors checked. Resurfacing or replacing them is often the fix. Also, inspect brake pads for uneven wear.
- Listen for squealing or grinding noises
- Feel for pulsation in the pedal
- Check brake fluid level and condition
Replacing brake pads and rotors on this vehicle typically costs $400 to $700 per axle.
Heating And Air Conditioning Issues
HVAC problems are also common. Owners report the air conditioning blowing warm air or the heater not getting hot. This can be due to a failing blend door actuator, a refrigerant leak, or a faulty compressor.
The blend door actuator is a plastic part that can break, causing the temperature to be stuck on one setting. Replacing it is tricky because it’s buried behind the dashboard.
- Air conditioning not cooling properly
- Heater only blows cold air
- Clicking noise from behind the dashboard
If you hear clicking when changing temperature settings, the blend door actuator is likely failing. Replacement costs vary but can be $200 to $500 at a shop.
Recalls And Service Campaigns
The 2012 Jeep Grand Cherokee Laredo has had several recalls over the years. These include issues with the airbag system, the fuel pump relay, and the steering column. Check with a dealer to see if any open recalls apply to your vehicle.
Recalls are fixed for free, so it’s worth verifying. You can also check the National Highway Traffic Safety Administration (NHTSA) website using your VIN.
- Airbag inflator recall (Takata)
- Fuel pump relay recall
- Steering column shaft recall
Don’t ignore recall notices. They address safety issues that could put you at risk.
How To Prevent Common Problems
Regular maintenance is the best way to avoid many of these issues. Follow the owner’s manual for oil changes, fluid checks, and inspections. Pay attention to warning lights and strange noises.
Here are a few tips to keep your 2012 Grand Cherokee Laredo running smoothly:
- Change oil every 5,000 miles or as recommended
- Flush transmission fluid every 60,000 miles
- Inspect suspension components annually
