2016 Jeep Patriot P0573 Code: Cruise Control/Brake Switch A Circuit High - Causes and Fixes

Model: Jeep Patriot Fault Code: P0573 Posted: 2019-03-28 09:48

I recently purchased a 2016 Jeep Patriot with approximately 95,000 miles on the odometer. Over the past few weeks, I've noticed that the vehicle hesitates when starting, especially in the mornings. It typically requires about three key turns before it finally starts. I took it to AutoZone for diagnostics, but they only connected the OBD2 scanner and failed to explain what the P0573 code meant. They simply suggested I search online. Given that this is a known issue with 2016 Jeep Patriot models, I'm wondering if the P0573 cruise control/brake switch A circuit high fault could be directly related to my starting hesitation. Could anyone confirm whether resolving this code might help fix the startup problem?

The P0573 diagnostic trouble code in a 2016 Jeep Patriot typically indicates an issue with the cruise control/brake switch A circuit. Possible causes include: a defective brake switch, wiring problems (such as pinched or chafed wires near the brake pedal), internal faults within the Engine Control Module (ECM), mechanical obstruction from debris or dirt preventing proper switch operation, or improper adjustment of the brake switch mount. Fixing this issue may resolve both cruise control malfunctions and intermittent starting hesitation. For reference: P0573 diagnostic code explanation.

Female user here — I didn't fully understand the technical details from the online sources, so I'm asking for clarification. The P0573 code is what I received at AutoZone, and I’m concerned it might be causing my Jeep’s hesitation during startup. I expected a technician to check basic components like battery health or alternator function as well, but they didn’t perform any of those checks. Any insight on whether this specific code could be linked to the starting issue would be greatly appreciated.

The hesitation during startup may be indirectly related to erratic cruise control behavior caused by a faulty brake switch or wiring. To address the P0573 code, follow the listed causes: inspect and clean the brake switch, verify proper mounting and adjustment, check for damaged wiring, and ensure no debris is interfering with operation. Once resolved, monitor whether the vehicle starts more smoothly in the mornings. Symptoms of a P0573 code may include: cruise control not working at all, erratic cruise behavior, failure to engage cruise, or absence of brake lights if the switch is faulty.
