Common Issues and Problems

Alright, let’s get into the nitty-gritty. The 2012 Jeep Grand Cherokee Overland Hemi isn't without its problems. Knowing these issues can help you make an informed decision if you're considering buying one or help you troubleshoot if you already own one.

Electrical Issues

One of the most common complaints about the 2012 Grand Cherokee is electrical problems. These can range from minor annoyances to major malfunctions. Some owners have reported issues with the Uconnect infotainment system, including freezing, crashing, and unresponsive touchscreens. Others have experienced problems with the power windows, door locks, and remote start. In some cases, these electrical issues can be traced to a faulty TIPM (Totally Integrated Power Module), which is a known problem in many Chrysler vehicles of this era. Replacing the TIPM can be expensive, so it's worth investigating if you're experiencing multiple electrical issues.

Air Suspension Problems

The Quadra-Lift air suspension is a great feature, but it can also be a source of problems. Some owners have reported issues with the air suspension compressor failing, which can cause the vehicle to sag or not raise properly. Others have experienced problems with the air struts leaking, which can also lead to ride height issues. Repairing the air suspension can be costly, so it's important to have it inspected if you notice any problems. Keep an eye out for warning lights or unusual noises coming from the suspension system. Regular maintenance, such as cleaning the air suspension components, can help prevent issues.

Hemi Engine Issues

While the Hemi engine is generally reliable, it's not immune to problems. Some owners have reported issues with the Hemi tick, which is a ticking noise that can be caused by various factors, including exhaust manifold leaks, lifter issues, or piston slap. While the Hemi tick is often harmless, it can be annoying. In some cases, it can be a sign of a more serious problem. Another potential issue with the Hemi engine is the MDS (Multi-Displacement System), which deactivates cylinders to improve fuel economy. Some owners have reported issues with the MDS system causing rough idling or hesitation. Regular oil changes and proper maintenance can help prevent these issues.

Transmission Problems

The 5-speed automatic transmission in the 2012 Grand Cherokee Overland Hemi is generally reliable, but it's not without its potential issues. Some owners have reported rough shifting or slipping, especially at higher mileage. These issues can be caused by worn clutches or a faulty valve body. Regular transmission fluid changes can help prevent these problems. It's also important to have the transmission inspected if you notice any unusual behavior.

Maintenance and Reliability

Maintaining a 2012 Jeep Grand Cherokee Overland Hemi is crucial to keeping it running smoothly and reliably. Regular maintenance, such as oil changes, filter replacements, and fluid checks, can help prevent many of the common issues. It's also important to address any problems promptly to prevent them from escalating into more serious issues. Overall, the 2012 Grand Cherokee Overland Hemi can be a reliable vehicle if properly maintained.

Tips for Maintaining Your Grand Cherokee

  • Follow the recommended maintenance schedule: Consult your owner's manual for the recommended maintenance intervals for your vehicle.
  • Use quality parts and fluids: Using high-quality parts and fluids can help ensure that your vehicle performs optimally and lasts longer.
  • Inspect your vehicle regularly: Regularly inspect your vehicle for any signs of problems, such as leaks, unusual noises, or warning lights.
  • Address problems promptly: Don't ignore problems, no matter how minor they may seem. Addressing them promptly can prevent them from escalating into more serious issues.
  • Keep your vehicle clean: Regularly washing and waxing your vehicle can help protect it from the elements and keep it looking its best.
