The failure pattern owners describe
Engine stalling dominates 2011 Grand Cherokee complaints. Owners report the engine dying at highway speeds, during turns, or while decelerating—often without warning lights. Power steering and brakes disable simultaneously, forcing drivers to coast to safety. Restart is usually possible after sitting briefly, but happens sporadically and repeatedly over months or years.
Owners and dealers commonly blame fuel pump relay failure under recall P54 (NHTSA 14V-530), but stalling persists even after relay replacement. Some shops later identified faulty wiring harnesses with bad crankshaft position sensor wires as the real culprit. One owner with a 2009 model had identical wiring issues resurface in a 2011, suggesting a design pattern.
Hard starting and extended crank times are separate but frequent complaints. Owners report needing multiple start attempts, sometimes waiting 15–30 minutes before the engine fires. The Totally Integrated Power Module (TIPM) is mentioned as the likely cause, but dealers struggle to source the part—some report back-orders of 5–6 weeks.
Misfires in cylinders (especially #2 and #3) appear linked to Pentastar 3.6L engines, with owners citing rounded camshafts and bad lifters as underlying causes. One owner faced a $4,600+ repair bill at 104,000 miles; another needed engine replacement at 70,000 miles.
Engine fires, broken crankshafts, loose timing components, and transmission cooler line disconnection represent severe but isolated failures in this cluster. A few owners also report A/C evaporator freezing and heater core overheating issues.

Failure modes owners describe
Engine Stalling During Driving
Engine shuts off unexpectedly while operating at any speed (highway, city streets, turns, or stop lights), disabling power steering and power brakes. Typically restarts after restart attempt. Recurs sporadically over months or years.
When: Most common 50,000–120,000 miles; some present from new (308 miles)
Symptoms owners cite: Engine dies without warning lights; Loss of power steering and brakes; Engine restarts after brief pause; Stalling occurs during turns, braking, or highway driving; Radio and headlights may remain on during stall
Codes mentioned: None found in many cases; dealers unable to replicate, FCW (Forward Collision Warning) light illuminated post-stall in some cases
Repairs/costs cited: Fuel pump relay replacement (recall P54, NHTSA 14V-530) does not resolve issue in multiple cases. Bad crankshaft position sensor wiring harness identified in some vehicles after extended diagnosis. Owner reports wiring harness replacement fixed problem.
Recalls/TSBs owners mention: Recall P54 (NHTSA 14V-530) issued for fuel pump relay. Later recall V62 (NHTSA 19V-813) acknowledges P54 fix defective and subject to silicon contamination. Recall repair parts frequently on back-order.
Hard Starting / Extended Crank Time
Engine requires multiple start attempts or takes 15–30 minutes to crank and fire. Problem worsens over time. Vehicle may fail to start entirely on occasions.
When: Begins at various mileages (5,000–60,000 miles); escalates over years
Symptoms owners cite: Prolonged cranking before ignition; Multiple failed start attempts; 15–30 minute delays before engine fires; Problem worse in cold weather (some reports); Eventually vehicle will not turn over
Codes mentioned: No codes in many cases
Repairs/costs cited: Totally Integrated Power Module (TIPM) identified as cause in multiple cases. Replacement performed in at least one case (#42). Parts availability is critical bottleneck—dealers report 5–6 week back-orders. Costs not consistently stated; one owner cited $2,400 rental-car expense during 3-month repair delay.
Recalls/TSBs owners mention: TIPM is recalled item; parts severely back-ordered. Recall T59 (NHTSA 17V-572) mentioned in one case as incomplete due to parts unavailability.
Cylinder Misfire (Pentastar 3.6L V6)
Check engine light triggered by misfire codes in cylinders #2, #3, or #6. Owners report loss of power, hesitation during acceleration, rough idle, or violent shaking when accelerating. Some result in engine needing replacement.
When: Occurs as early as 308 miles; also at 56,000–104,000 miles
Symptoms owners cite: Misfire code illuminates check engine light; Loss of power during acceleration; Violent shaking when attempting to pass or merge; Rough idle or hesitation; In advanced cases: no restart
Codes mentioned: Misfire codes (cylinder-specific: #2, #3, #6), Check engine light (MIL)
Repairs/costs cited: Root causes identified include coil failure (part not available at time of complaint), rounded camshaft with bad lifters ($4,600+ minimum repair, parts back-ordered; $8,600 for full engine replacement at 104,000 miles), and cylinder head gasket failure requiring head replacement ($1,893 parts/labor). One owner cited Pentastar extended warranty coverage by Chrysler but was denied due to salvage title on vehicle.
Recalls/TSBs owners mention: Chrysler extended warranty mentioned as covering Pentastar head/camshaft defects, but applied selectively. Owner reported being told 'it just happens sometimes' and outside warranty at 7 years. Some dealers acknowledge the problem but offer no recall or assistance.
Hard-Start / No-Start with Fuel Pump Relay
Vehicle cranks but does not start; often attributed to fuel pump relay malfunction. Difficult for shops to diagnose due to intermittent nature. Fuel pump relay replacement under recall does not always resolve the issue.
When: Intermittent; can occur at any mileage
Symptoms owners cite: Starter motor cranks but engine does not turn over; Multiple start attempts eventually succeed; Problem intermittent and hard to reproduce; Dealers often cannot find fault codes
Codes mentioned: No diagnostic codes in many cases
Repairs/costs cited: Fuel pump relay identified and replaced in multiple cases. However, misdiagnosis is common—shops often incorrectly attribute hard-start to relay when wiring harness or other components are at fault. Relay parts themselves are in short supply.
Recalls/TSBs owners mention: Fuel pump relay recalled (P54, NHTSA 14V-530). Replacement relays have limited availability, causing months-long delays.
Wiring Harness Defect (Crankshaft Position Sensor Wire)
Bad wire inside engine wiring harness connecting timing/crankshaft sensor causes intermittent engine stalling or hard-start symptoms. Issue difficult to diagnose and replicate. Shops may misattribute failure to fuel pump relay.
When: Intermittent; recurs months or years after initial complaint
Symptoms owners cite: Engine stalls randomly or during specific driving conditions; Hard starting; Problem intermittent, difficult for shops to verify; Restart succeeds after pause
Codes mentioned: No codes initially; requires road testing and harness inspection
Repairs/costs cited: Wire replacement inside harness fixed the problem in reported cases. One owner's 2009 model had identical issue; same wiring harness failure recurred in owner's 2011 model years later, suggesting systemic design defect. Repair requires removal and inspection of wiring harness.
Recalls/TSBs owners mention: No manufacturer response or recall mentioned for this specific wiring defect.
Fuel Pump and Fuel System Component Failures
Fuel pump relay or fuel pump failure causing hard-start, no-start, or stalling. Recall P54 issued but parts remain unavailable for extended periods.
When: 50,000–130,000 miles
Symptoms owners cite: Hard or impossible start; Stalling during operation; Intermittent failure
Repairs/costs cited: Fuel pump and fuel pump relays replaced under recall P54. However, parts availability severely limited—owners report waiting months for replacement components.
Recalls/TSBs owners mention: Recall P54 (NHTSA 14V-530) issued for fuel pump relay defect.
Transmission Cooler Line Disconnection
Transmission cooler lines at radiator disconnect or come loose due to improper connection, spraying transmission fluid and causing vehicle to lose power on highway.
When: Approximately 56,000 miles (one case)
Symptoms owners cite: White steam/smoke from under hood; Smell of hot transmission fluid; Vehicle loses power; Large pool of fluid under vehicle
Repairs/costs cited: Technician reconnected and clamped both transmission cooler lines. Topped off fluid (6 quarts ATF+4 used). Owner concerned because failure occurred on high-speed highway exit and could have caused accident.
Engine Fire
Engine caught fire and burned entire engine compartment and front of vehicle shortly after coil misfire diagnosis at dealership.
When: 308 miles on odometer (new vehicle); approximately 2 miles after leaving dealership
Symptoms owners cite: Engine fire, visible flames; Complete destruction of engine compartment and front of vehicle
Codes mentioned: Misfire – coil failure (#6 cylinder)
Repairs/costs cited: Dealership diagnosed #6 cylinder coil failure but advised coil part not available. Suggested local driving only. Owner drove 2 miles and engine caught fire.
Broken Crankshaft
Crankshaft breaks internally without warning, causing sudden loss of power and engine shutdown while driving at highway speed.
When: 114,000 miles
Symptoms owners cite: RPM spike followed by RPM drop; Loud noise from under hood; Complete loss of engine power; No warning light prior to failure
Repairs/costs cited: Dealership confirmed internal crankshaft defect. Owner provided service records showing regular oil changes. Dealership cited workmanship defect. Engine replacement quoted at $7,800. Owner still owed ~$13,000 on vehicle loan.
Recalls/TSBs owners mention: Chrysler refused assistance citing mileage (114,000 miles). Dealership offered no good-will assistance.
Loose Timing Components / Timing Chain Failure
Timing components come loose from engine block, interfere with timing chain, and snap it. Causes catastrophic valve train damage.
When: 170,000 miles
Symptoms owners cite: Engine stalls at highway speed; Check engine light with camshaft sensor code; Engine will not restart; Loud noise from engine on initial failure
Codes mentioned: Camshaft sensor code
Repairs/costs cited: Technician found timing components loose and timing chain snapped. Engine requires replacement due to damage to irreplaceable camshaft bearings in block. Estimated repair cost $5,000–$7,000. Warranty expired at 170,000 miles.
Remote Keyless Entry Module / Push-Button Start Failure
Remote keyless entry module loses communication with other vehicle modules, causing complete electrical system shutdown while driving. Vehicle cannot be restarted using push-button; physical key fob in ignition slot restarts vehicle.
When: Early in vehicle life (January 2013 complaint)
Symptoms owners cite: Engine stalls while driving; All electrical systems disable: steering, brakes, lights, dashboard dark; Only radio/navigation and center console 'how to start' text display remain on; Push-button start and brake pedal unresponsive; Owner must manually shift into park to stop vehicle
Repairs/costs cited: Dealership performed module software update on remote keyless entry module and other associated modules. However, technician could not guarantee it would not happen again. Failure recurred on January 9, 2013 with same symptoms. Physical key fob placed in ignition slot restored normal start function.
Recalls/TSBs owners mention: Module software update performed as warranty repair.
Alternator Diode Failure
Alternator diodes fail rapidly, causing output variability (no output, reduced output, or fully shorted to ground). Electrical system voltage drops to critical levels, disabling safety systems.
When: Not specified
Symptoms owners cite: Vehicle electrical system voltage drops critically; ABS, ESC, ECM, and Central Body Controller disabled; Limited warning of alternator failure; Potential under-hood electrical fire; Vehicle shutdown while driving
Repairs/costs cited: One 2011 Grand Cherokee owner reports experiencing exact alternator malfunction described in Recall P60 (NHTSA 14V-634), but Chrysler does not recognize their vehicle as included in the recall despite matching symptoms and model year.
Recalls/TSBs owners mention: Recall P60 (NHTSA 14V-634) issued for 160-amp alternator diode failure in 2011–2014 Dodge/Chrysler/Jeep models. Owner reports their 2011 Grand Cherokee not included despite meeting criteria.
Engine Overheating / Cooling System Defect (Towing)
Engine cannot adequately cool when towing approximately 3,500 lbs uphill. Vehicle loses power abruptly, slowing to 27 mph on highway, creating dangerous traffic situation. Advertised tow capacity is 5,000 lbs unrestricted with tow package.
When: During towing on uphill highway sections
Symptoms owners cite: Sudden loss of power while towing uphill; Vehicle speed drops from 65 mph to 27 mph without warning; No warning lights; Creates dangerous condition in passing lanes
Recalls/TSBs owners mention: Chrysler confirmed the problem exists but refused to address it via recall, insisting vehicles operate as designed. Owner alleges Chrysler prioritizes cost over safety.
Engine Overheating / Radiator Hose Deterioration
Radiator hose fails, causing engine overheating, stalling, and power loss while driving on highway in hot weather.
When: Occurred 30 minutes after oil change in 112-degree heat
Symptoms owners cite: Engine overheats; Engine stalls; Steering locks (power steering disabled); Brakes harden (brake assist disabled); Vehicle cannot be restarted or put in neutral
Repairs/costs cited: Owner was advised during oil change that radiator hoses looked soft and needed replacement. Failure occurred 30 minutes later on freeway.
Heater Core Overheating / Housing Melt
Heater core housing melts from extreme heat under dashboard. Repeated failure (third replacement) suggests design or installation defect.
When: Approximately 10+ years of ownership; third replacement by May 2019
Symptoms owners cite: Abnormal heat on feet/legs from engine compartment during cold months; A/C failure; Extreme under-dashboard heat causing housing to melt
Repairs/costs cited: Dealership replaced heater core, housing, blend doors, and actuators. Housing had melted from extreme heat. Cost $2,200 for repair. Owner notes this is third replacement of same components.
A/C Evaporator Freezing
A/C evaporator freezes after 3 hours of driving with A/C in use, causing air to stop flowing from vents despite compressor running.
When: After extended A/C use (3+ hours)
Symptoms owners cite: Air stops blowing from vents after 3 hours of A/C use; Compressor continues running; Blockage due to evaporator freeze
Repairs/costs cited: Dealership advised owner that Chrysler is aware of the recurring problem but has determined not to fix it. Recommended workaround: use A/C on warmer setting or turn it off and wait for thaw.
Recalls/TSBs owners mention: Chrysler acknowledged problem but refused to provide recall or warranty repair. Dealership offered no solution.
Oil Filter Housing Crack
Oil filter housing develops crack, causing oil leak. Repair not performed due to cost and high mileage denial.
When: 89,000 miles
Symptoms owners cite: Oil leak underneath vehicle
Repairs/costs cited: Oil filter housing replacement needed. Cost not quoted. Dealership refused repair due to manufacturer denying coverage on high-mileage vehicle.
Recalls/TSBs owners mention: Manufacturer denied repair claim citing high mileage.
Thermostat Repeated Failure
Thermostat fails and must be replaced multiple times. Owner reports seven replacements over vehicle lifetime.
When: 90,000 miles (initial diagnosis); recurring
Symptoms owners cite: Unknown warning lights illuminate; Vehicle loses power or stability
Repairs/costs cited: Thermostat replaced seven times at dealership. No parts cost or labor cost specified. Pattern suggests underlying design issue rather than component failure.
Totally Integrated Power Module (TIPM) Failure
TIPM fails, causing no-start, hard-start, or stalling. Parts severely back-ordered; dealers cannot source replacements for months.
When: Various mileages; some very early in ownership
Symptoms owners cite: Hard or impossible start; Starter noise without engine firing; Stalling while driving; Horn activates randomly
Repairs/costs cited: TIPM replacement necessary. Parts back-ordered 5–6 weeks or longer in multiple reports. One owner had recall notice but part never became available over 1+ year period.
Recalls/TSBs owners mention: TIPM recall issued (T59, NHTSA 17V-572 mentioned in one case); however, replacement parts have severe supply constraints. Recall marked 'incomplete' due to parts unavailability.
Blower Fan / Defroster Relay Failure
Blower fan relay burns out, causing TIPM failure and defroster inoperability.
When: Unknown mileage
Symptoms owners cite: Defroster does not operate; Blower fan inoperative
Repairs/costs cited: Relay replacement and TIPM replacement required. Estimate provided but vehicle not repaired at time of complaint.
Recalls/TSBs owners mention: Manufacturer informed contact no recalls on vehicle. Estimate obtained from dealer.
Engine Replacement Due to Pentastar Defect
