The contact owns a 2020 Jeep Grand Cherokee. The contact stated that while his wife was driving at an undisclosed speed, the vehicle stalled. Several unknown warning lights illuminated on the instrument cluster. The vehicle was towed to the dealer and diagnosed with 45 error codes relating to the vehicle not being able to communicate with the blind spot and doors due to battery failure. The battery was replaced; however, the failure recurred. The vehicle was towed back to the dealer. The contact was uncertain if the dealer diagnosed the vehicle with engine control module (ECM) or body control module (BCM) failure. The dealer informed the contact that the windshield seal was not installed correctly during manufacturing, which caused water to seep in and damage the engine control module (ECM) or body control module (BCM). The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure but informed the contact that the vehicle was not covered since it did not have an extended warranty. The failure mileage was 14,787.
