The 2012 Jeep Grand Cherokee is a popular SUV that has garnered attention for its performance and features. However, it has also faced issues related to the fuel pump relay, particularly concerning its reliability and functionality. This article aims to provide essential information about the fuel pump relay, its symptoms, potential solutions, and recall details.

Understanding the Fuel Pump Relay

The fuel pump relay in the 2012 Jeep Grand Cherokee is a critical component located within the Totally Integrated Power Module (TIPM). Its primary function is to control power to the fuel pump, ensuring that fuel is delivered to the engine when needed. Unfortunately, this relay can fail due to various factors, often leading to significant operational issues.

Common Symptoms of Fuel Pump Relay Failure

Owners of the 2012 Jeep Grand Cherokee may experience several symptoms indicative of a failing fuel pump relay:

  • Intermittent Starting Issues: Difficulty starting the vehicle, especially in cold weather.
  • Engine Stalling: The engine may stall unexpectedly while driving, which can pose safety risks.
  • No Start Condition: The vehicle may fail to start altogether, often requiring multiple attempts.
  • Battery Drainage: A stuck relay can cause the fuel pump to run continuously, draining the battery.

These symptoms can progressively worsen over time, leading to more severe problems if not addressed promptly.

Solutions for Fuel Pump Relay Problems

If you suspect issues with your fuel pump relay, there are several steps you can take:

  • Testing the Relay: Use a multimeter to test the relay's functionality. If it fails, consider replacing it with a new one.
  • Bypassing the Relay: For immediate relief, some owners opt for a bypass solution that allows the fuel pump to operate directly from another power source.
  • Professional Inspection: If DIY solutions do not resolve the issue, visiting a certified mechanic or dealership for a thorough inspection is recommended.

Recall Information

The 2012 Jeep Grand Cherokee was part of several recalls related to the fuel pump relay. Specifically, recall V62 addressed concerns about silicon contamination affecting relay contacts. This contamination could lead to relay failure, resulting in no-start conditions or engine stalls while driving. The remedy involved replacing affected relays and harness connectors at no cost to the vehicle owner.
