The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Certain brands of Cell Phone Chargers may produce Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI) that can disrupt the electrical systems within the vehicle. This interference can cause a no start condition with a "No Fobs Detected" message on the DIC. The concerns created by the use of these chargers may be intermittent and random. The concerns can be present with or without the phone connected to the charger. This condition usually occurs when using a non name-brand charger.

Recommendation/Instructions:

Disconnect the cell phone charger from the vehicle and evaluate the customer concern. If the concern is corrected, advise the customer that OEM cell phone chargers, provided by the cell phone manufacture, typically have additional filtering to eliminate this type of interference.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
