2017 Jeep Grand Cherokee electrical system problems

“After purchasing the Jeep Cherokee Laredo 2017 in 2024, The jeep immediately in November/2024 started giving problems with the engine, I did report these issues to Belise Kia in West Springfield, Ma, after I dropped of the Jeep in July/2025, I was told that the jeep needed a new engine. In January/2026 I got the jeep back, but the issues remain. I`ve tried to do the inspection and the Jeep failed due to PO349, PO345, UO415 and P1009 sensors. I did report these issues to Belise Kia and their response was " we did what we need to do with the Jeep which it was changed the engine. But the engine does not appear to be replaced. I do not know what else to do.”

The vehicle was taken to an independent mechanic, where unknown parts needed to be replaced. The vehicle was repaired; however, the failure persisted.

Yes. The vehicle was taken immediately to an independent service center following the incident and has remained there due to the severity of the malfunction. The service…”
