What stands out
Owners have filed 84 powertrain complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Powertrain accounts for 23% of all owner complaints filed against this vehicle, across 12 categories tracked.
The failure pattern owners describe
Buyer takeaway: A used 2017 Grand Cherokee is a significant risk purchase due to widespread, recurrent transmission and drivetrain electrical faults that strike unpredictably—sometimes early, sometimes late in ownership—and cost $8,000+ to repair after warranty expires. Dealer fixes are often temporary, and Jeep has not addressed the root cause despite multiple campaigns and complaints.
2017 Grand Cherokee owners describe a pattern of severe powertrain failures that Jeep has not solved. The transmission becomes stuck in single gears (1st, 3rd, 7th, 8th) without warning—often at traffic lights or highway speeds—with "Service Shifter" and "Shift Denied" messages appearing. When it does shift, transmission bangs violently like a hammer strike, especially during slow acceleration at partial throttle (5–35%). Dealership software flashes are listed as fixes for a "known issue," but failures recur within weeks.
Loss of power happens suddenly. The engine revs but the vehicle doesn't move, or throttle gets stuck at 4500–6000 RPM and won't respond to releasing the pedal. The power transfer unit (PTU) grinds and fails, eliminating 4WD. On inclines, vehicles roll backward while in Park despite the parking brake. Stop/start systems fail to restart, trapping owners in traffic with the shifter locked. Electronic shift modules require replacement ($900+); software updates make some vehicles completely inoperable.
The CAN bus (vehicle network) cuts out on the highway, killing all electronics mid-drive. Oil cooler housings crack, mixing oil with coolant and draining the engine without any warning light. Driveshaft nuts back off, and replacement parts vanish from supply chains. Owners report dealerships replaced transmissions only to see identical failures return within months, and Jeep often claims specific VINs are not covered by recall despite identical complaints across the model year.

Failure modes owners describe
Transmission Shift Refusal / Lockup
Transmission becomes stuck in a single gear (1st, 3rd, 7th, 8th reported) or fails to shift out of park, often triggered by electrical faults. Owners report 'shift denied' messages, 'service shifter' warnings, and repeated downshift/upshift failures. Multiple restart cycles sometimes required to restore function.
When: Primarily on initial acceleration from stops or during normal driving; some occur after 50K miles, others at 150K+ miles
Symptoms owners cite: Transmission stuck in single gear; unable to shift manually or automatically; Downshift refusal at low speeds (below 10 MPH); 'Service Shifter' and 'Shift Denied' warning messages; Multiple warning lights (check engine, ABS, ESC, 4WD) illuminate simultaneously; Vehicle cannot be shifted to park or neutral; Repeated occurrence after 'fix' within weeks
Codes mentioned: P076F, U0001, U1199, P00FD, U0447, P02D1, P1DCA
Repairs/costs cited: Dealership transmission flash/software update ($200+); Electronic Shift Module (ESM) replacement ($900); complete transmission replacement ($8,100). Some owners report flash updates listed as 'known issue' but problem recurs within 3 weeks.
Recalls/TSBs owners mention: Jeep dealers acknowledge 'known issue' and provide software updates, but many owners report problems persist post-update. NHTSA Campaign 25V011000 (Powertrain) referenced by some owners; manufacturer sometimes states VIN not included in recall.
Hard / Violent Transmission Shifts & Banging
Transmission produces loud banging, clunking, or shuddering during shifts, particularly when accelerating slowly toward shift points at partial throttle. Owners describe impacts like a '5 lb hammer' on the vehicle frame. Issues occur in mid-range gears (6th–8th) and during routine driving.
When: Primarily after 50K miles; can occur during mixed highway/city driving (reported 5–10 bangs per 20-minute drive)
Symptoms owners cite: Loud banging or clunking sound during transmission shift; Vehicle shudders or jolts when shifting; Hard downshift impact, sometimes feels like bumps or violent bangs; Slipping sensation followed by sudden gear engagement; Most common at 5–35% throttle during slow acceleration
Codes mentioned: P076F
Repairs/costs cited: Valve body replacement attempted (made problem worse for one owner); complete transmission replacement ordered (on back order, no ETA given). Owners cite transmission replacement costs of $8,100 or more.
Loss of Propulsion / Unresponsive Acceleration
Transmission fails to engage power despite throttle input. Vehicle loses motive power mid-drive, leaves owner stranded or barely mobile on roadways. Often accompanied by warning messages like 'Shift to Park' and multiple dash lights.
When: Reported at various mileages (13K–180K); can occur during city driving, highway entry, or when stopped at traffic lights
Symptoms owners cite: Engine revs but vehicle does not move (in Drive or Reverse); Vehicle fails to accelerate when gas pedal depressed; Sudden loss of power while driving; Vehicle stalls or becomes stuck in park/single gear; 'Transmission Overheated' message displayed; Accompanying warning messages ('Service Shifter', 'Service 4WD', 'Shift to Park')
Codes mentioned: P076F, P00FD
Repairs/costs cited: Transmission replacement ($8,000+) required in most cases. Mobile mechanic diagnosis of 'transmission failure' noted in one case at 181K miles. Owners cite no warning before sudden failure.
Recalls/TSBs owners mention: Manufacturer not always made aware; when contacted, some owners told VIN not under recall despite similar complaints online.
Power Transfer Unit (PTU) Failure
Power transfer unit fails, causing loss of 4WD functionality, abnormal grinding/banging noises from drivetrain, and loss of motive power. Shear pins fail; PTU connection breaks. Failures can follow recent driveshaft replacement.
When: Reported at 61K, 130K, and 150K miles; one failure one month after driveshaft replacement
Symptoms owners cite: Grinding or banging noise from underneath vehicle; 'Service 4WD' warning light illuminated; Loss of motive power (vehicle will not move); Abnormal sound near driver's feet during acceleration or U-turn; Vehicle loses 4WD functionality; Shear pins and PTU connection fail
Repairs/costs cited: Driveshaft replacement; PTU replacement required. One owner had driveshaft replaced one month prior, then PTU failed.
Recalls/TSBs owners mention: Manufacturer confirms NHTSA Campaign 20V343000 and 25V011000 (Powertrain) in some cases; however, some owners told VIN not included in recall despite having failure.
Transmission Overheating & Limp Mode
Transmission displays 'Transmission Overheated' message and enters reduced-power state. Vehicle may fail to accelerate, stall, or become stuck in a single gear. Issues persist after cooling and restart.
When: Reported during city driving and at traffic stops; one case at 35 MPH, another while stopped at traffic light
Symptoms owners cite: 'Transmission Overheated' message on instrument panel; Vehicle fails to accelerate as intended; Abnormal sound from powertrain; Vehicle stalls or loses power; Rough driving after restart
Repairs/costs cited: Mobile mechanic diagnosed transmission failure; vehicle not repaired. Another owner parked vehicle out of safety concerns.
Shifter / Electronic Shift Module (ESM) Malfunction
Shifter becomes unresponsive, stuck, or displays erratic warning lights. Electronic shift module fails, sometimes after a dealership software flash update. Shifter lights flash continuously; messages display without user input.
When: Can occur very early (3,500 miles reported); also at 55K miles; continuous flashing reported overnight
Symptoms owners cite: Shifter lights flashing continuously or intermittently; Shifter stuck in park; cannot move selector; 'Service Shifter' warning light illuminated; Messages like 'Place car in Park then Select Gear' appear unexpectedly; Ignition stays on after engine shut off; Vehicle will not start after shifter malfunction
Repairs/costs cited: Electronic Shift Module (ESM) replacement ($900) required. One owner's dealership software flash rendered vehicle inoperable; ESM replacement was 'irreversible' and new part not immediately available.
Recalls/TSBs owners mention: Dealership offers software flash as remedy, but failures persist post-update. Some owners report this is a 'very common problem.'
Unintended / Stuck Throttle Acceleration
Engine revs uncontrollably or throttle remains 'stuck' at high RPM (4500–6000) even when foot is removed from gas pedal. Most reported in ECO mode or at traffic lights. Requires shifting to neutral and braking to regain control.
When: Reported 4 times in 3 weeks (ECO mode); another case 10 months after purchase with 4–5 incidents
Symptoms owners cite: Engine races to 4500–6000 RPM without driver input; Throttle will not slow down when foot removed from pedal; Occurs in ECO mode or when starting from stops; Requires shifting to neutral and heavy braking to control; No mechanical obstruction found (floor mat, pedal mechanism clear)
Repairs/costs cited: Software update attempted; problem persisted. Dealership unable to resolve issue after being notified.
Recalls/TSBs owners mention: Dealership notified; software update provided but did not resolve problem. Owner notes similar complaints from owners of SRT and Trackhawk trims.
Vehicle Roll-Away in Park
Vehicle rolls backward or forward when in Park, even with parking brake applied. Occurs on slight inclines and flat surfaces. Poses immediate crash and injury risk, particularly when vehicle is unoccupied or with passengers.
When: Reported on inclined driveway (20–30 degree slopes) and flat terrain; one case with vehicle running and unoccupied
Symptoms owners cite: Vehicle rolls backward or forward while in Park with engine running; Occurs when exiting vehicle or door is opened; Parking brake does not prevent roll-away; Shifter confirmed in Park position but vehicle still moves; Can roll 300+ feet before hitting obstacle
Repairs/costs cited: No repairs documented in most complaints. One case required boulder to stop vehicle; another required multiple attempts to shift out of park using Low 4WD and Snow mode.
Recalls/TSBs owners mention: One dealer told owner that roll-away behavior is 'designed' for vehicles of that year/model; no recall initiated.
Stop/Start System Failure & Engine Stall
Auto stop/start feature shuts engine off at traffic lights or stops but fails to restart. Vehicle becomes trapped with shifter locked in Park, unable to move or be towed. Multiple restart attempts required (10–12 trials reported).
When: Occurred 4 times within 6 months of purchase; one case early in vehicle's life (6 months old, brand new)
Symptoms owners cite: Engine shuts down via stop/start system but fails to restart; Shifter locked in Park; cannot shift to Neutral; Vehicle immobilized in traffic; Multiple restart attempts required to restore function; Battery warning lights and brake light illumination
Repairs/costs cited: Auxiliary battery replaced; then main battery replaced; finally, loose battery wire connector to starter was tightened. Dealer had to service battery connections three times.
Recalls/TSBs owners mention: Dealer provided override option to bypass Park gear lock, but owner found it difficult to locate/use.
Driveshaft & Transmission Yoke Failure
Driveshaft nut backs off, causing driveshaft to separate from transmission yoke/flange. Results in clanking noise, loss of power, and vehicle immobilization. Replacement parts difficult to source.
When: Reported within first year of ownership; one case after less than 4 months in shop
Symptoms owners cite: Clanking noise when backing out of driveway; Driveshaft nut found loose; Yoke, flange, and driveshaft damaged; Driveshaft moves around, creating noise
Repairs/costs cited: Driveshaft replacement required; replacement flanges difficult to source (vehicle in shop 4 months). Repair turned over to Chrysler for part sourcing.
CAN Bus / Electrical Network Failure
CAN bus (vehicle electrical communication network) stops working without warning, causing total powertrain failure on highway. All controller icons illuminate on dash; shifter and transmission become unresponsive. Vehicle complete restart sometimes restores partial function.
When: Reported while driving 70 MPH on highway and in subsequent incidents; one case required $700 shifter replacement
Symptoms owners cite: All dashboard warning lights illuminate simultaneously; Shifter and transmission stop responding; Vehicle loses all electronic control; Braking system affected; Repeated failure after repair attempt
Repairs/costs cited: Shifter replaced ($700); problem recurred the next day. Owner researched and found issue common across 2014–2022 Jeep models with electric CAN bus drivetrains.
Oil Cooler Housing Failure / Mixing of Oil & Coolant
Plastic oil cooler housing cracks, allowing engine oil to mix with coolant system. Oil drains from engine without triggering warning lights. Creates fire hazard; vehicle becomes stranded without prior warning.
When: Reported after 60-mile drive from home to work with no warnings displayed
Symptoms owners cite: No check engine light or overheat warning before failure; Oil leaks into coolant system; Complete oil drainage from engine; Vehicle stranded at destination; Unknown seal in coolant system leaking
Repairs/costs cited: Oil cooler housing must be replaced; plastic housing noted as design flaw.
Gear Shift Selector Malfunction / Non-Responsive Selector
Gear shift selector becomes stuck, non-responsive, or difficult to move. Vehicle may jolt aggressively when shifted; selector may be locked in Park or unable to move to desired gear despite force applied.
When: Reported at very low mileage (12K miles) and at higher mileage (150K+)
Symptoms owners cite: Gear selector stuck in Park position; Selector will not move despite force applied; Vehicle jolts aggressively when selector is shifted; Messages display: 'Place car in Park then Select Gear'; Selector locked; cannot manually override
Repairs/costs cited: Drivetrain replacement attempted (problem persisted); dealer uncertain about diagnosis due to conflicting codes.
Recalls/TSBs owners mention: Manufacturer notified; one case resulted in drivetrain replacement, but problem returned.

What owners are reporting 3 most recent
Sitting in my driveway waiting for my daughter, vehicle was in park on a very, very small incline - almost flat. Within a minute of sitting there, it started to coast/move backwards. I had to put my foot on the brake to stop it from going onto the road.
My car recently started making a grinding noise that got bad really fast. I had it towed to the dealership to get a diagnostic test done. I was told that it was my transfer case that was making the noise. Now this caught me by surprise because I had no warning lamps on my dashboard or no messages alerting me of any problems that would point to it needing servicing done it just happened out the…
