    The abs module on many of these vehicles has a known fault. You can’t find replacement parts, even the Jeep dealership can’t get them. Many ppl are driving around with faulty modules, on a waiting list for parts. I’m one of those people. All has been fine until I was driving toward 228 business in Angleton to turn towards Walmart. I was going about 45-48 and went to brake to slow down for the stop sign. My brakes were soft instead of firm and it locked up and skid on me. I didn’t hit anything but had someone been behind me it could have been different. It scared me. Now I’m scared to drive it and have no fix for it.

    For the past two years I have experience intermittent problems with my Jeep ABS system, I ordered the replacement module part # 68145835AE from an authorized dealership on April 2025, and paid $697.39 after more than a year on back order the sales representative told me to cancel the order because they did not have any information form Stellantis North America on when the part will be available. This is the second complaint I filed with NHTSA in a year and I plan to go up to the President if I have to since this is safety concern.

  • Engine 11/29/2024

    The engine's cylinder head/valve train has failed internally, allowing combustion gases to enter the cooling system — confirmed via a chemical block test performed by a master automotive technician on November 29, 2024, which verified combustion gases present in the coolant. This is a widely documented defect on this engine and model year, related to valve seat erosion in the cylinder head. Symptoms first appeared in June 2018 as an unusual higher-pitched, stressed sound from the engine. Over time this progressed to recurring, confirmed misfires on cylinders 1, 2, 3, and 5 (diagnostic codes P0300, P0301, P0302, P0303, P0305) and a mixture control fault (P219B). The check engine light has intermittently stayed illuminated for months at a time, then gone off for extended periods while the same fault codes remain stored and confirmed by a diagnostic scanner — currently the light is off but the codes persist. The vehicle frequently runs rough enough that the engine must be turned off and...
