What stands out
Owners have filed 60 engine 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.
Among the 13 model years of Chrysler 300 in our records for engine problems, this one ranks #3 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering engine on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
Owners report catastrophic engine failures across a wide range of mileage, from as low as 44,600 miles to over 260,000 miles. The most common and severe failure is valve seat fracture—the intake or exhaust valve seat simply cracks and drops into the cylinder, causing immediate internal damage that requires complete engine rebuild or replacement ($3000–$8750 each time). Some owners experienced this twice on the same vehicle.
Cooling fan separation ranks second: the electric radiator fan's blades separate during normal operation, puncture the radiator, dump coolant, and cause the engine to overheat and die. A recall (L08, June 2011) addresses this for certain production dates and sales codes, but many owners with identical failures report Chrysler denied coverage because their VIN fell outside the narrow cutoff window.
Engine stalling without warning is widespread. The motor dies at idle or while driving, then restarts after cycling the ignition. No check engine light appears. Dealers cannot replicate the failure and offer no fix. One owner had it happen at least 10 times over ownership and counts this as life-threatening.
Secondary failures include oil pump collapse (engine locks up with no prior symptoms despite clear oil), head gasket failure that recurs after multiple repairs, radiator coolant fan thermostat failure, piston and rod bearing collapse, transmission leaks at low mileage, and engine fires. Air intake positioned low on the front bumper allows water ingestion during flooding. One owner's new engine caught fire while parked.

Recalls/TSBs owners mention: No recalls or TSB coverage reported for this defect
Radiator Cooling Fan Separation
Electric radiator cooling fan blades separate during operation and puncture or damage the radiator. Some owners denied coverage under recall L08 (June 2011) claiming their VIN fell outside the cutoff date despite identical failure.

Intake Air Hydrolock from Water Ingestion
Engine air intake positioned low on front bumper (approximately 20 inches from ground) allows water entry during flooding or heavy rain/street water spray, causing hydro-lock.
When: During flooding event with 3 inches standing water; occurs during initial water crossing

Repairs/costs cited: Engine replacement (water damage)
Recalls/TSBs owners mention: No recalls or design change notification found in narratives
Engine Stalling/Loss of Power While Driving
Engine dies or loses power without warning during normal operation at various speeds and conditions. Can occur intermittently over years of ownership. Restart possible by turning key off and back on or pumping throttle, but failure recurs.
When: Occurs intermittently starting early in ownership; 25,000 miles onward; reported at least 10+ occurrences per owner
Symptoms owners cite: Sudden engine shutdown with no warning; Loss of power steering (hard to turn wheel); Vehicle slows to stop or complete stop; No check engine light illuminated; Restart possible by cycling ignition; Recurs without pattern related to speed, weather, or cruise control

When: February 24, 2020; recent purchase owner
Symptoms owners cite: Fire in engine compartment; Rod shot through oil pan; No prior warning signs
Repairs/costs cited: Engine replacement required; dealer quoted $4200 exploratory fee plus engine replacement (used engine offered under warranty)
Recalls/TSBs owners mention: Warranty coverage disputed; dealer required upfront $4200 diagnostic fee
Intake Manifold/Tuning Valve Failure
Check engine light illuminates due to intake manifold tuning valve or short runner valve control issues. Recurs after dealer repair attempts.
When: 7,000 miles (12-2008)
Symptoms owners cite: Check engine light illuminated; Engine runs rough or loses power
Codes mentioned: Intake manifold tuning valve failure, Short runner valve control code
Repairs/costs cited: Dealership replaced components; light reset multiple times
Recalls/TSBs owners mention: None documented
Oil Pump Failure/Sludge Accumulation

Recalls/TSBs owners mention: Warranty denied; dealer blamed owner maintenance despite documented service history
Head Gasket Failure/Overheating
Head gasket fails causing vehicle to overheat. Problem recurs after multiple repair attempts. Oil mixes with coolant, indicating internal sealing failure.
When: Unknown mileage; recurred multiple times

Common questions
How serious is the engine problem on the 2007 Chrysler 300?
It's a documented issue but not catastrophic. 60 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.
At what mileage does the engine typically fail?
Across the 48 complaints that reported odometer mileage, most engine failures cluster between 39,000 and 123,750 miles, with the median around 82,847. A quarter of owners report trouble before 39,000; a quarter make it past 123,750. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
