2017 Jeep Wrangler brakes problems

Front and/or rear calipers lock up or stick during normal driving, causing excessive drag, overheating, smoke, rotor damage, and uneven pad wear. Owners report the vehicle pulling to the affected side, brake pedal becoming harder to depress, and dangerous loss of braking control.

When: Reported at mileage ranging from 15,000 to 91,914 miles; multiple recurrences within 1–2 years on same vehicle

Symptoms owners cite: Brake dragging and creeping while in Drive at idle; Excessive heat, smoke, and burning smell from affected wheel; Steering pull to the locked-up side; Hardened brake pedal (fluid not returning to master cylinder); Uneven front or rear brake pad wear; Vehicle difficult to move when brakes applied at traffic light or stop sign; Squeaking and jumping sensation when accelerating

Repairs/costs cited: Replacement of calipers, rotors, brake pads, hoses, and in some cases cylinders. Costs reported: $970–$2,100 per repair; one owner spent over $6,000 after four complete brake jobs at 40,000 miles. Rear caliper replacement on a 2017 JKU cost $1,427.15 at 60,000 miles. Another owner replaced all four calipers multiple times under warranty then out-of-warranty.

Recalls/TSBs owners mention: FCA provided replacement brake calipers for all 4 wheels and failed brake hose at no charge in one case (complaint #28) after NHTSA complaint filed. Another owner found a reimbursement precedent in forums for the same issue.

Brake hoses collapse internally or become pinched, preventing brake fluid return to the master cylinder. Results in pedal going soft, loss of brake pressure, and brake lock-up or drag.

When: Multiple occurrences; first hose replacement at rear, followed by front hose collapse later, sometimes within warranty then recurrence out-of-warranty

Symptoms owners cite: Spongy or soft brake pedal; Brake pedal goes to floor; Loss of braking ability or inability to stop; Brakes dragging and locking up; Brake fluid not returning to master cylinder; Second or third occurrence of same issue on same vehicle

Repairs/costs cited: Replacement of brake hoses, calipers, rotors, and brake pads. One owner reported two occurrences: first covered under warranty, second cost $1,000; then front hoses failed, costing $640. Another owner noted the bracket crimping the hose at the axle connection is suspected cause.

Recalls/TSBs owners mention: Power Stop brake hose kit was recalled (part# BH00139, Recall 24E-053) due to leaks; one owner had front hose begin to leak, losing brake pressure.

Master cylinder develops internal leaks or internal failure; fluid leaks into the brake booster. Brake pedal goes to floor, vehicle loses braking or continues to coast even with pedal fully engaged.

When: Reported at 6 months post-purchase and after multiple incidents; failure confirmed after three roll-forward collisions

Symptoms owners cite: Spongy brakes with decreased stopping ability lasting 6 months; Brake pedal goes completely to floor; Vehicle rolls forward at stop despite brake fully engaged; Brake failure at traffic light, stop sign, and drive-thru; Brakes never fully lock before ABS engages post-repair; Lingering 'play' in brakes after dealer repair

Repairs/costs cited: Replacement of master cylinder, HCU (hydraulic control unit), and brake booster. One vehicle had three separate roll-forward collisions before root cause identified. Owner traded vehicle in as unsafe for teenage driver.

Recalls/TSBs owners mention: Dealership identified internal leak at master cylinder and HCU internal failure; vehicle was held 6+ weeks for repairs and picked up August 15, 2018.

ABS module stops functioning, triggering constant warning lights (ABS, Traction Control, sometimes ESC and Brake lights). Vehicle loses anti-lock braking safety feature. Some modules internally fail; parts are on chronic backorder or out of production.

When: Failures reported at 17,300 to 63,000 miles; one owner waiting 6+ weeks, another over 1 year for part

Symptoms owners cite: ABS warning light constantly illuminated; Traction control light on; ESC (electronic stability control) light on; Cruise control stops functioning; Brakes 'default' to ABS ratchet mode even at slow speeds; Vehicle slides when brakes applied downhill due to ABS malfunction; No warning before failure; Loss of anti-lock feature; braking feel abnormal

Codes mentioned: C2200 (ABS internal failure), C1252-92 (Vacuum Pump Control Circuit), P258B (Electronic Vacuum Pump Performance)

Repairs/costs cited: Replacement ABS module (part# 68259556AD). One owner was told part is in such high demand it will take months; another was told part not in production due to engineering issue with no ETA; another waited 6+ weeks with no resolution. Multiple owners driving without ABS due to unavailability.

Recalls/TSBs owners mention: Jeep/FCA TSB S1805000006 (released 02/24/2020) addresses vacuum pump and ABS fault codes but does not resolve module shortage. Jeep is re-engineering the module per complaints; no recall issued despite known recurring issue.

Electronic vacuum pump that powers the brake booster stops functioning or maintains insufficient vacuum. Check engine light illuminates with vacuum pump diagnostic codes.

When: Check engine light triggered; vehicle in for diagnosis at dealership

Symptoms owners cite: Check engine light illuminated; ESC light illuminated; Loss of vacuum in brake booster circuit

Codes mentioned: C1252-92 (Vacuum Pump Control Circuit), P258B (Electronic Vacuum Pump Performance)

Repairs/costs cited: TSB S1805000006 instructs technician to check vacuum pump operation, fusing, wiring, connectors, hoses, and check valves; no part replacement specified in narrative.

Recalls/TSBs owners mention: FCA TSB S1805000006 (Release Date: 02/24/2020) issued for Symptom/Vehicle Issue: ESC Light Illuminated.

Rear brake wheel speed sensors malfunction or have open wiring, causing loss of ABS signal and triggering warning lights. Vehicle may apply brakes automatically or lose ABS control.

When: Reported at 35,000 miles and in other incidents; wiring issues found on multiple Jeeps same day

Symptoms owners cite: Vehicle jerks and comes to abrupt stop without warning; ABS and traction control lights illuminated; Vehicle applies brakes automatically even at 5 mph; Applying gas does nothing when ABS/traction lights are on; No warning lights initially, then ABS lights activate post-incident

Codes mentioned: Speed sensor fault codes (not specified in detail)

Repairs/costs cited: Replacement of left and rear right wheel speed sensors. One shop reported three other Jeeps had the same issue the same day.

Recalls/TSBs owners mention: Repair not covered under warranty in one case; part availability was cited as reason repair could not be completed.

The pin holding the brake pedal to the firewall comes loose after the e-clip on one end of the pin falls out. Critical safety issue as brake pedal can become non-functional.

When: Occurred while pulling into a parking spot

Symptoms owners cite: Brake pedal assembly loosens from firewall; E-clip falls off retaining pin

Engine cylinders misfire; separate issue of major oil filter housing leak, front drive shaft grease leak, and coolant/radiator leak reported. Owner notes these are common issues post-50,000 miles when warranty expires.

When: Oil/coolant issues at 52,000 miles; cylinder misfire 2 months prior to complaint; previous complaint 60,000 miles with all 4 calipers seized

Symptoms owners cite: Check engine light (related to cylinder misfire); Burning smell when heater turned on; Oil leaking from filter housing; Front drive shaft leaking grease; Coolant and radiator empty; Radiator leaking

Repairs/costs cited: Oil filter housing was fixed by dealer; owner told vehicle can be driven while waiting on other repairs. Radiator leak noted as common issue post-warranty.

Recalls/TSBs owners mention: Dealer stated this is a common issue; manufacturer aware but will not acknowledge it and considers it customer responsibility post-50,000 miles and out-of-warranty.
