2005 Chrysler 300 powertrain problems

The transmission shifter interlock lever, a pink plastic component, breaks internally (most commonly a tiny tab holding the return spring), trapping the shift selector in Park. The failure occurs without warning, sometimes after extended periods of non-use or with repeated shifting cycles. Owners report the shifter becomes completely immobilized despite brake pedal applied; some can temporarily free it by manually manipulating the mechanism through the console or with a screwdriver, but the problem recurs. The defect has a known remedy via Recall K39 (NHTSA 05V460000) but Chrysler applied it selectively—only to certain VINs—leaving many identical 2005–2007 vehicles and early 2004 build units without coverage despite exhibiting the same failure mode.

When: Can occur from early ownership (noted at 44,240 miles) through high mileage (102,600+ miles); failures reported at 37,454 miles, 54,000 miles, 92,000–98,500 miles, and beyond. Some occur after the vehicle sits parked for days.

Symptoms owners cite: Shifter completely immobilized in Park position; Brake pedal applied but shifter will not move; Engine on or off makes no difference; Manual override procedure (pink button per owner manual) does not function; No warning lights or system indicators beforehand; Repeated attempts (5–20+ cycles) to shift yield no movement

Repairs/costs cited: Complete shifter assembly replacement, $300–$600+ labor and parts; dealers often refuse to sell the pink plastic piece separately. Some owners self-repaired by purchasing aftermarket metal replacement (e.g., Dorman part #924-706, ~$15) or salvage-yard parts. Temporary workarounds: manual depression of the internal mechanism through the console opening, or using a screwdriver to manipulate the shifter cable. Towing costs $150–$250. At least one owner received reimbursement after paying out-of-pocket when Chrysler's K39 notification promised to reimburse if documented, though others were denied because their VIN fell outside the recall batch.

Recalls/TSBs owners mention: Recall K39 (NHTSA Campaign 05V460000) issued; however, Chrysler limited coverage to 'some' 2005–2007 model years and selected VINs. Early 2004 builds excluded despite identical defect. Owners report dealers stating 'Your VIN is not included in the recall' even when presenting the recall notice. Chrysler customer service told several owners they 'could not duplicate the problem' or that the issue was normal computer adaptation. One owner received a Customer Satisfaction Notification K39 letter stating it applies to 'some 2005 through 2007' vehicles but their VIN was denied coverage. Chrysler initially offered reimbursement on receipts but denied others post-hoc. No universal recall expansion for all affected vehicles.

Vehicle suddenly accelerates or lurches forward while stationary at a traffic light or intersection, even when brake pedal is firmly depressed. The surge happens without operator input and can cause the vehicle to collide with vehicles ahead. Owners report multiple episodes over months, regardless of engine temperature (cold start or fully warm). One documented rear-end collision occurred; the dealer could not duplicate the problem and attributed it to 'electronics adjusting to driving style,' which proved incorrect. Internet research by the owner revealed others experienced the same issue on Chrysler 300 forums, indicating it is not isolated.

When: Occurs while stopped at traffic lights, in traffic, or at intersections. Can happen multiple times (eight reported instances in one complaint). No specific mileage threshold noted; one owner reported it early in vehicle ownership.

Symptoms owners cite: Sudden, unexplained forward lunge or acceleration while vehicle is stationary; Firm brake pedal application does not prevent the surge; No warning or indication before the event; Occurs both on cold start and after warm-up; Multiple occurrences over months; Resulted in rear-end collision of another vehicle

Repairs/costs cited: Dealer stated inability to replicate or identify cause; owner offered to bring vehicle to dealer's lot for real-world observation but was declined. No repair attempted. Owner requested documentation from Chrysler proving the defect exists to present to insurance company after accident.

Recalls/TSBs owners mention: Dealer said 'nothing like this before' and could not duplicate. Chrysler responded to the complaint with denial of known issue. Owner found forum discussions from other 2005 Chrysler 300 owners describing identical behavior.

Engine dies without warning while vehicle is in motion at highway speeds (50 mph) or city speeds. In some cases the engine restarts immediately; in others it takes multiple restart attempts or a wait of several minutes. One owner reported the vehicle died on the freeway and again shortly after; another was stranded at an intersection when the engine died and would not restart for extended periods. Power steering is lost when the engine dies, creating potential collision hazard. Documented cases include stalling after fuel tank is filled to capacity (with additional cases showing a pattern triggered by overfilling the tank near the automatic pump shutoff point).

When: Reported at various mileage points: 24 miles into a trip after parking, while at highway speeds, at traffic lights after leaving work, and consistently when fuel tank is filled to near-maximum capacity. One new-vehicle purchaser experienced multiple stalls within the first few miles of ownership.

Symptoms owners cite: Engine suddenly dies while driving; Loss of power steering (when engine is off); Difficult or slow restart after stall; Multiple stalls in succession while driving; Vehicle stranded and requiring tow; Stalling triggered by filling fuel tank to capacity or near-maximum; After tank is filled to near-full, stalling occurs for the next 15–20 miles or more

Repairs/costs cited: No repairs documented in the narratives. One new-car buyer asked dealer about recall applicability; another owner attempted to avoid overfilling but the dealer workaround (filling to one gallon below full) is not a permanent fix. Owner spending significant time at gas stations due to inability to fill tank fully.

Recalls/TSBs owners mention: No known manufacturer response or recall documented in these narratives for the stall issue. One owner noted a Service Bulletin 2101105 REVA issued April 23, 2005, regarding transmission design defect, but no recall action.

Transmission fluid becomes contaminated with water despite vehicle never being submerged or driven through high water. The air conditioning drain tube leaks water directly into the transmission, causing fluid degradation and eventual transmission failure. Dealer acknowledged the air conditioner drain tube was the source in at least one case. Transmission had to be flushed and fluid replaced, but water reappeared; ultimately the transmission failed completely 2,000 miles after the initial repair and required full transmission replacement. Chrysler refused responsibility, citing the absence of a transmission dipstick that would allow owners to check fluid condition and detect the contamination early.

When: Noted at approximately 95,000 miles and 105,000 miles (failure occurred 2,000 miles after initial water-contamination diagnosis).

Symptoms owners cite: Transmission fluid appears contaminated with water (milky appearance or water droplets); Vehicle has not been in flood or high water; Transmission shifts hesitantly or slips; Transmission eventually fails completely; No warning lights or diagnostic indicators alert owner to water presence

Repairs/costs cited: Transmission fluid drained and replaced twice to remove water; 2,000 miles later transmission required full replacement (cost not specified but implies thousands of dollars). Owner later learned dealer and Chrysler service centers acknowledge this is a known problem with 300C models.

Recalls/TSBs owners mention: Chrysler refused to take responsibility, claiming the vehicle design (lack of accessible transmission dipstick) made it impossible for them to determine how water entered. They declined warranty assistance or cost-sharing for transmission replacement. Dealers acknowledged the problem is common in the model line.

Transmission produces a loud bang, clunking, or clanging noise when shifting from first to second gear, or exhibits hesitation/delay in engaging the next gear. The sound resembles transmission slipping or a loose driveshaft. The problem occurs consistently in afternoon conditions after the vehicle has warmed up, triggered by ambient or engine temperature extremes (hot or cold). Dealer could not reproduce the problem and refused house-call diagnostics despite being only 2 miles away.

When: Reported from day one of ownership; evident after a 45-minute warm-up drive, typically in afternoon temperature conditions. Persisted for at least two years and 79,000 miles without resolution.

Symptoms owners cite: Loud bang or clanging noise when shifting from first to second gear; Transmission hesitation or delay in gear engagement; Sound consistent with transmission slip or loose driveshaft; Problem triggered by hot or cold ambient temperatures; Occurs reliably in the afternoon after vehicle has warmed up

Repairs/costs cited: No repair documented. Dealer advised they cannot duplicate the problem in the service bay and will not perform real-world diagnostics. Owner continues to drive the vehicle with the issue unresolved.

Recalls/TSBs owners mention: None documented. Dealer declined to investigate.

While downshifting, the transmission unexpectedly disengages and shifts into Neutral without operator input. Vehicle then coasts uncontrolled, requiring the driver to pull over and wait several minutes before the engine can be restarted. Power is lost and vehicle must coast to safety. The failure is attributed to air conditioner drain tube leaking water into the transmission case, contaminating the fluid. Transmission replacement was recommended.

When: Noted at approximately 95,000 miles; current mileage 105,000 miles at time of complaint.

Symptoms owners cite: Transmission shifts into Neutral unexpectedly while downshifting; Vehicle coasts uncontrolled without power; Engine dies and requires several minutes before restart; Loss of power steering during the episode

Repairs/costs cited: Transmission replacement recommended; repair was not completed at time of complaint.

Recalls/TSBs owners mention: Manufacturer was contacted and offered no assistance. Dealer advised A/C drain leak caused the water intrusion into transmission.

Engine suffers sudden, severe internal damage when a valve drops into the combustion chamber, causing catastrophic piston and cylinder-head damage. The failure occurs abruptly during normal driving; engine dies and will not restart. Thousands of owners on internet forums report identical failures on 2005 Chrysler 300 models. The cost to repair is $4,000–$7,000, often exceeding the vehicle's remaining warranty by only 1,000 miles (engine damage occurring at 101,000 miles when warranty expires at 100,000 miles). Chrysler does not acknowledge or issue recalls for this defect despite widespread forum reports.

When: Reported at 101,000 miles (1,000 miles past the 100,000-mile warranty limit); other owners report similar failures with similar mileage overruns.

Symptoms owners cite: Engine dies suddenly during normal driving; Engine will not restart; Mechanical damage to engine confirmed by inspection; Valve found to have dropped into cylinder; Catastrophic damage to pistons and cylinder head

Repairs/costs cited: Engine rebuild or replacement required at a cost of $4,000–$7,000. Owner was forced to secure a $6,000 loan to repair the vehicle. One owner notes the repair cost alone exceeds typical vehicle value at that mileage.

Recalls/TSBs owners mention: Chrysler has not issued a recall or acknowledged the problem despite thousands of reports on owner forums. Owner was denied warranty coverage because the failure occurred 1,000 miles beyond the 100,000-mile warranty cutoff.

While the vehicle is parked with the engine running and driver has exited, the car suddenly begins to move backward in Reverse gear without any input from the driver. The vehicle crashes through poles and into oncoming traffic before crashing into a neighbor's fence. The driver was struck by the driver's-side door when attempting to stop the vehicle and sustained injuries. This is identical to the failure mode covered by Recall 05V460000 (E14); however, Chrysler denied coverage because the vehicle was built one month before the recall cutoff date.

When: The vehicle was parked with the engine running; no specific mileage noted but current mileage was approximately 95,000 miles.

Symptoms owners cite: Vehicle in Park with engine running; Vehicle suddenly shifts into Reverse and moves backward without driver input; Vehicle accelerates and crashes through objects; No warning or control by driver to prevent the movement; Vehicle enters traffic and collides with property

Repairs/costs cited: Vehicle was taken to authorized dealer but was not repaired at time of complaint.

Recalls/TSBs owners mention: Chrysler Recall E14 (NHTSA 05V460000) directly addresses this failure but Chrysler denied coverage based on build date being one month before the recall campaign cutoff, despite the identical defect being present.

Engine stalls and shuts off while driving; simultaneously the wheels lock without warning, causing complete loss of vehicle control. The vehicle will not restart after the stall. Diagnosis indicates an unknown part in the dashboard ignition assembly is damaged and requires replacement. No recall exists for this failure.

When: Occurred at approximately 115,000 miles; vehicle had approximately 115,000 miles at time of report.

Symptoms owners cite: Engine suddenly stalls while driving; Wheels lock simultaneously with stall; Complete loss of steering and braking control; Engine will not restart; No warning indicators

Repairs/costs cited: Dealer diagnosed an unknown part in the dashboard ignition assembly as damaged and needing replacement; estimated cost not specified. Repair was not completed.

Recalls/TSBs owners mention: Manufacturer was made aware; no recall exists. Technician noted an air-bag repair in 2018 but stated it would not have caused this failure.

Engine develops heavy sludge deposits and begins clacking, smoking, and losing power (shaking, nearly stalling during operation). The 2.7-liter engine is known to have a chronic sludge problem. Warranty is valid to 80,000 miles, and the vehicle has 78,844 miles; however, the dealer refused to honor the warranty, claiming the sludge indicates owner negligence in oil changes. Owner's husband maintained the vehicle on schedule. The owner filed a complaint with the state Attorney General, noting that Chrysler is aware of a known 2.7-engine sludge defect but the dealer uses owner oil-change records as an excuse to deny warranty coverage.

When: Occurs near the end of the 80,000-mile warranty period (78,844 miles) with evidence of years of accumulated sludge.

Symptoms owners cite: Engine clacking noise; Engine smoking; Engine shaking during operation; Engine nearly stalls while driving; Heavy sludge buildup in engine; Loss of engine power

Repairs/costs cited: Warranty was denied by dealer; vehicle was left at Chrysler service center awaiting owner pickup. No repair costs provided but warranty coverage would have been full if honored.

Recalls/TSBs owners mention: No documented response from Chrysler manufacturer. Dealer denied warranty claim. Owner is pursuing complaint through state Attorney General's office, noting Chrysler's awareness of the 2.7-engine sludge defect in the industry.

Shifter assembly requires replacement multiple times over vehicle ownership. First shifter replaced at 37,454 miles due to inability to release from Park; second shifter replaced at approximately 60,000 miles for the same failure. After the second replacement, Chrysler added a small new clip to the design (a band-aid fix) rather than initiating a full recall. The defective design continues to fail even with the added clip. The same clip-modification design change was applied to other Chrysler models (Avengers, Sebrings) rather than conducting a proper recall or redesign.

When: First failure at 37,454 miles; second failure approximately 4 years later (by 2012, second replacement made); problem recurs almost immediately after repair.

Symptoms owners cite: Shifter cannot move out of Park; Problem recurs shortly after full shifter replacement; Multiple replacements required over vehicle lifespan

Repairs/costs cited: First replacement (9/4/2008): $508 for shifter unit 4578029AC. Second replacement (9/19/2012): $560 for shifter unit 68091343AA with a new clip added to the design. Each replacement is a full shifter assembly; the part is not sold separately. Owner notes Chrysler chose to apply small design-change fixes (clips) to multiple model lines rather than issuing comprehensive recalls.

Recalls/TSBs owners mention: Chrysler denied responsibility when owner wrote a letter of complaint about the repeated failures and design defect. No acknowledgment of the pattern or commitment to a comprehensive fix.

The gear shifter becomes stuck in Park position and cannot be moved, even when the owner attempts to use the manual emergency-release procedure documented in the owner's manual. The manual instructs the owner to depress a pink button next to the gear shift to release the interlock. However, the pink button is not mechanically connected to anything (disconnected or never installed properly), making the documented procedure entirely non-functional. A certified technician had to disassemble the console to manually release the shifter mechanism. The entire shifter assembly was subsequently replaced by the dealer at significant cost, but the dealer could not explain why the pink button was non-functional or why the shifter failed in the first place.

When: The issue arose during normal vehicle use; no specific mileage provided in the narrative.

Symptoms owners cite: Shifter stuck in Park position—cannot be removed; Difficulty putting car into Park position at times; Manual emergency release (pink button per owner manual) does not function; Pink button is physically disconnected from the internal mechanism; No warning or indication of failure

Repairs/costs cited: Entire shifter assembly replacement required: approximately $375 for labor plus cost of the part, which was on backorder for three days. Owner incurred towing costs (~$150) to avoid using dealer tow service. Certified technician noted the pink button was not connected.

Recalls/TSBs owners mention: Dealer stated no recalls exist for this type of repair and that the cost is owner's responsibility. Dealer could not explain the failure or why the manual procedure was non-functional. Owner requested the failed part be sent to the manufacturer for analysis but no response is documented.

Vehicle exhibits a persistent hesitation and noise whenever backing up or turning out of the driveway. The noise/hesitation has been present for over eight to ten years (51,152 miles of driving). The owner complained at the first service visit (1,199 miles in 2008) and again in 2010 (18,309 miles); both times the dealer performed a check and road test, concluding 'vehicle operating as designed.' In 2016, during routine service, the technician noticed the same hesitation/noise while backing the vehicle out of the service bay and recommended a diagnostic. The technician reported that the rear axles and drive needed to be replaced and warned that if driven further the components may seize up. Despite thirty service visits over ten years at only two dealerships, the underlying defect was never identified until a technician noticed it incidentally.

When: Present since early in vehicle ownership (noticed at 1,199 miles); persisted through 51,152 miles and over ten years of ownership.

Symptoms owners cite: Hesitation when backing up or turning out of driveway; Persistent noise during reverse motion or turning maneuvers; Noise present regardless of temperature or load; Risk of seize-up if driving continues without repair

Repairs/costs cited: Rear axles/drive components need replacement; cost not specified. Repair was recommended but not completed at time of complaint.

Recalls/TSBs owners mention: None documented. Dealer technicians dismissed the complaint as normal operation until 2016 when a different technician recognized the issue.
