2013 Jeep Grand Cherokee brakes problems

Brake booster shell ingests water in wet conditions (rain, snow, fog, car washing) causing corrosion, loss of vacuum assist, and total or partial braking failure. Failure occurs most often in freezing temperatures when moisture freezes inside the booster. Owners report being unable to stop, needing to pump brakes repeatedly, and having mushy or nonresponsive pedals.

When: Typically 2-4 years after original recall repair; failures reported in 2016-2017 on vehicles that had recall work done in 2014. Mileage range 10,000-72,000.

Symptoms owners cite: Brake pedal goes to floor with no stopping power; Hard/firm brake pedal requiring excessive force; Brake pedal seized or frozen, won't respond; Brakes fail to slow vehicle at all speeds (20-70 mph); Loss of braking effectiveness in cold/wet weather; Vacuum leak hissing sound; Pedal feels spongy after bleeding ABS

Codes mentioned: 14V154000, 17V572000

Repairs/costs cited: Brake booster and master cylinder replacement required. Owners report $700 out-of-pocket costs when repeat failure occurs outside warranty. ABS system bleeding needed after booster replacement.

Recalls/TSBs owners mention: Recall 14V154000 issued in June-July 2014; replacement boosters themselves later found to be defective and also recalled. Repair covered under warranty only if recall not yet performed; owners who completed the recall are denied coverage on repeat failures, citing the repair was already completed.

Ready Alert Braking system fails to engage or provide proper braking response, causing hard brake pedal and inadequate vehicle deceleration. System designed to warn of obstacles ahead and ready the brakes; failure creates dangerous delay in actual braking.

When: Failures reported 2014-2016, approximately 2 years into ownership. One crash caused injuries (broken ankle) when brakes failed.

Symptoms owners cite: Hard brake pedal requiring added force to depress; Brake pedal firm and difficult to apply; Vehicle fails to slow as needed despite pedal application; BRAKES warning light displayed on instrument panel; System fails to ready brakes for upcoming stops

Codes mentioned: 14V104000

Repairs/costs cited: RAB system replacement required. Chrysler denies some repairs citing VIN does not match build records showing RAB installed, despite owner documentation and dealership test drive demonstrations confirming system was present.

Recalls/TSBs owners mention: Recall 14V104000 issued in 2014 for hard pedal due to RAB failure. Chrysler refuses to honor some claims, telling owners their vehicle was not built with RAB despite physical evidence and dealer confirmation. One owner told to contact insurance rather than manufacturer.

Brake pedal locks or freezes solid at highway speeds, becoming immovable and unresponsive to foot pressure. Occurs intermittently; pedal regains function after releasing and reapplying pressure multiple times. Dealers unable to replicate issue or find root cause.

When: Multiple occurrences at highway speeds (40-70 mph); some owners report 6+ instances. Early 2014 models reported issue at 1,500 miles.

Symptoms owners cite: Brake pedal locked/frozen and will not move; No braking response when pedal depressed; Pedal regains function only after release and reapplication; Occurs intermittently, not consistently reproducible; Affects normal highway braking

Repairs/costs cited: No repair completed; dealers unable to diagnose. Master cylinder and vacuum assembly hose were replaced on one vehicle without resolving the issue. Owners continue to drive with unresolved intermittent brake failure.

Massive parts shortage and supply chain collapse for brake booster recall 14V154000. Dealers receive only 1-4 parts per month; waiting lists of 30-800+ customers; repair timelines extend from initial June 2014 announcement through September 2014 and beyond with no parts ETA. Some dealers unable to staff recalls; others never contact customers about scheduled appointments.

When: May-September 2014 initial shortage; delays extend into 2015 and beyond. One owner reports waiting from June 2014 with no resolution by December 2014.

Symptoms owners cite: Parts unavailable at dealer; Waiting lists with 30-800+ vehicles ahead; Only 1-4 parts delivered per month per dealer; No estimated time for parts arrival; Dealer loses customer on handwritten waiting list; Dealer unable to staff recall work; Confirmed appointments cancelled due to lack of mechanics

Codes mentioned: 14V154000

Repairs/costs cited: No parts available for repair during critical time window. Owners left with defective brakes during winter months when freezing and moisture issues most critical.

Recalls/TSBs owners mention: Chrysler acknowledged 'controlled recall' but unable/unwilling to expedite parts production. Manufacturer tells owners parts are 'on the way' for months with no updates. Chrysler support line dismisses owner safety concerns; some supervisors unreachable. Later replacement booster parts also recalled.

Complete brake failure on nearly-new vehicles before recall program was announced or applied. Owners experience sudden loss of all braking function at low speeds (1 mph, parking lot) requiring emergency evasion. Repeat failures within weeks on same vehicle.

When: March-April 2013; very low mileage (2,410 miles, 1,500 miles). Failures occurred before June 2014 recall.

Symptoms owners cite: No brake pressure at all when pedal applied; Vehicle does not stop despite pedal depression; Brake pedal not responding; Multiple failures within weeks on same vehicle

Repairs/costs cited: Vacuum pump replacement on one vehicle; no repairs completed on others. Dealers claim 'nothing wrong with brakes' and hold owner responsible for damage from failures.
