TIPM / power-module faults causing no-start, stalling and electrical gremlins
Chrysler products of this era, including the 300C, are known for TIPM (Totally Integrated Power Module - the smart fuse box) faults. A failing TIPM can cut power to the fuel-pump relay, giving a crank-but-no-start or a stall while driving, and can cause random electrical gremlins - lights, wipers, horn or door locks acting on their own. It can be intermittent, which makes it maddening to diagnose, and a replacement module plus programming isn't cheap.
What you would notice
- Crank but no start, sometimes intermittent
- Stalling while driving
- Fuel pump running when the car is off, or not priming
- Random electrical faults - wipers, lights, locks, horn
Typically $500–$1,800 to put right.

015.7 Hemi MDS Lifter Failure

02High-pressure fuel pump can break up and send debris through the fuel system, loss of power, recall Z46 (LX2 300 3.0 V6 turbo-diesel, REC-005648)

Ask for the service history and look for a dealer invoice showing Chrysler/Stellantis recall Z46 or a high-pressure fuel pump replacement.diesel2012–2015EngineCan't confirm for this car$0–$9,000

OccasionalEngine $0–$9,000 to fix

Can't confirm for this car

On the second-generation (LX2) Chrysler 300 with the 3.0 V6 turbo-diesel, the high-pressure fuel pump can fail early and shed debris into the fuel system, which can starve the engine and cause a loss of power while driving. Stellantis Australia recalled these cars in 2023 under campaign Z46 (REC-005648, the same campaign as the 3.0 diesel Grand Cherokee). When the recall was announced parts were not yet available, so check the repair has actually been done. Outside the recall, a pump failure that spreads debris to the rail and injectors is a large bill.

Symptoms to notice

Sudden loss of power or the car going into limp mode
Hard starting or cutting out
Engine warning light

What to check

Ask for the service history and look for a dealer invoice showing Chrysler/Stellantis recall Z46 or a high-pressure fuel pump replacement.
Ask if the seller got a recall letter and whether the repair was done once parts arrived.
On the test drive, accelerate firmly from low speed and up a hill: any hesitation, power loss or limp mode is a warning.
Check the engine warning light goes out after starting.
If a workshop inspection is possible: have the VIN checked for open recalls and scan for fuel rail pressure fault codes.

Where to look: High-pressure diesel fuel pump in the engine bay, feeding the common rail and injectors

Parts involved: High-pressure fuel pump, Turbocharger.

Ask the seller

“Has recall Z46 (high-pressure fuel pump) been done on this car?”
“Has the car ever lost power or gone into limp mode?”
“Has the fuel pump or any injector been replaced?”

03Left cylinder head valve seat and guide wear, misfire (3.6 Pentastar V6, LX2 Chrysler 300 2011-2013)

Start the engine from cold and listen at idle for a ticking or uneven beat; a healthy Pentastar idles smoothly.petrol2011–2013EngineCan't confirm for this car$2,500–$5,000

OccasionalEngine $2,500–$5,000 to fix

Can't confirm for this car

Early 3.6 Pentastar V6 engines (sales code ERB) in 2011 to 2013 LX2 Chrysler 300 models can wear the valve guides and valve seats in the left cylinder head, so cylinders 2, 4 or 6 lose compression and misfire. Chrysler admitted the problem: in the US it extended the warranty on the left head to 10 years or 150,000 miles (warranty bulletin D-14-12) and told dealers to leak test the cylinders and replace the head (service bulletin 09-002-14). Australian 2012 cars built before late July 2012 are named in that service bulletin, but the extended warranty was a US program, so do not count on it here. Left alone it gets worse and the cure is a replacement head.

Symptoms to notice

Check engine light, sometimes flashing
Rough idle or shake, worse when cold
Ticking or tapping from one side of the engine
Loss of power

What to check

Start the engine from cold and listen at idle for a ticking or uneven beat; a healthy Pentastar idles smoothly.
Watch the dash for a check engine light during the test drive and feel for any stumble or shake when pulling away and at steady low speed.
Ask whether the left cylinder head has been replaced and ask for the invoice.
If a workshop inspection is possible: scan for stored misfire codes on cylinders 2, 4 or 6 and run a cylinder leakage test on those cylinders.

Where to look: Engine bay, the left bank cylinder head of the V6 (cylinders 2, 4 and 6)

Parts involved: Cylinder head.

Ask the seller

“Has the left cylinder head ever been replaced, and do you have the invoice?”
“Has the check engine light come on or has it been treated for a misfire?”
“Was this car new in Australia or New Zealand, or a US import, and what is its build date?”

043.6 Pentastar Cam Phaser Rattle on Cold Start

Cold start the engine and listen immediately for phaser rattle — a metallic tapping from the cam cover area.petrol2011–2018EngineCan't confirm for this car$1,800–$4,000

CommonEngine $1,800–$4,000 to fix

Can't confirm for this car

The 3.6L Pentastar V6 in second-generation 300C models (LD) exhibits a distinctive cam phaser rattle on cold startup, typically lasting 2–5 seconds until oil pressure builds. The VVT phasers run on engine oil pressure and can wear internally or stick when oil is cold and thick. Progressive wear leads to timing-related fault codes, rough cold running, and eventual phaser replacement. The fault is widespread across all Pentastar applications (300C, Journey, Cherokee, Jeep Grand Cherokee).

Symptoms to notice

Rattling or tapping from engine on cold start, lasting 2–5 seconds
Check engine light with cam timing / VVT fault codes (P0011, P0014, P0016)
Rough idle on cold start
Hesitation under acceleration when cold

What to check

Cold start the engine and listen immediately for phaser rattle — a metallic tapping from the cam cover area. Scan for cam phaser or VVT fault codes. Check oil grade and change interval — incorrect or degraded oil worsens wear. On high-mileage examples, budget for phaser replacement.

Where to look: Front of engine — camshaft VVT phaser units, both intake and exhaust cams per bank

Ask the seller

“Any rattle or noise on cold startup?”
“Has the car had any cam timing or VVT fault codes?”
“What oil grade and change interval has been used?”

053.6 Pentastar cylinder-head 'tick' and rocker/needle-bearing wear

Let it idle warm and listen for a tick, and feel for a misfire.petrol2011–2014EngineCan't confirm for this car$800–$4,000

OccasionalEngine $800–$4,000 to fix

Can't confirm for this car

Early 3.6 Pentastar engines (particularly 2011-2013 builds) suffered a left-bank cylinder-head fault causing a tick, misfire and rough running - Chrysler extended warranty coverage on the heads for affected vehicles (bulletin D-14-12) and revised the parts. Separately the Pentastar's roller rockers use tiny needle bearings that can collapse; the roller then seizes and grinds a flat on the camshaft, giving a persistent tick and eventual engine damage. On a used 300C, a rough-running or ticking Pentastar needs a proper look.

Symptoms to notice

Tick or tap from the top of the engine
Misfire, rough idle or check-engine light (often cyl 2/4/6 - left bank)
Loss of power
Hesitation on acceleration

What to check

Let it idle warm and listen for a tick, and feel for a misfire. Ask if this is an early (2011-2013) build and whether the cylinder head or rockers were replaced under the extended coverage - get paperwork. Have it scanned for misfire codes concentrated on one bank.

Where to look: Cylinder heads and rocker/valvetrain on the V6 engine (left bank most affected)

Parts involved: Cylinder head.

Ask the seller

“Has the cylinder head or any rockers been replaced, and is there paperwork?”
“Does it ever tick, misfire or run rough?”

06NAG1 5-Speed Auto Solenoid Pack Failure

Test drive with multiple full-throttle and light-throttle shift events across all gears.2004–2018TransmissionCan't confirm for this car$1,500–$3,500

OccasionalTransmission $1,500–$3,500 to fix

Can't confirm for this car

The Mercedes-derived NAG1 (W5A580) 5-speed automatic fitted to 300C models with 5.7 Hemi and V6 is generally robust but suffers from solenoid pack failure over time. The solenoid body controls all hydraulic shifting; when solenoids wear, the transmission exhibits harsh or delayed shifts, slip between gears, or refuses to engage certain ratios. A solenoid pack replacement is common at 150,000–200,000 km. Full fluid and filter maintenance history significantly affects longevity.

Symptoms to notice

Harsh or clunky gear changes
Transmission slip or flare between gears
Delayed engagement from park into drive or reverse
Check engine / transmission warning light with shift solenoid codes
Transmission stuck in limp mode

What to check

Test drive with multiple full-throttle and light-throttle shift events across all gears.
Check for any harshness, slip, or hesitation between ratios.
Scan for transmission fault codes.
Check transmission fluid level and colour — dark or burned fluid suggests neglect.
Verify fluid and filter change history.

Where to look: Transmission valve body — internal solenoid pack accessed from sump pan

Parts involved: Mechatronic / valve body.

Ask the seller

“Has the transmission fluid and filter been changed, and when?”
“Any harsh shifts, slip, or transmission warning lights?”
“Has the solenoid pack been serviced or replaced?”

01LX2 300C alternator diode failure, stalling and fire risk recall (petrol, 2011-2014)

Ask for proof the alternator recall has been done (a dealer invoice or recall record).petrol2011–2014ElectricalCan't confirm for this car$0–$1,500

OccasionalElectrical $0–$1,500 to fix

Can't confirm for this car

On 2011 to 2014 LX2 Chrysler 300 models with the 3.6 Pentastar V6 or 5.7 Hemi V8 and electro-hydraulic power steering, the diodes inside the alternator can crack from heat, so charging voltage drops. That can switch off ABS and stability control, stall the engine while driving, and in some cases the failing alternator can overheat and catch fire. It was recalled in Australia (PRA 2017/16284) and the US (14V-634, then 17V-435, FCA campaign T36). The fix is a free alternator replacement, so check that the recall work has been done.

Symptoms to notice

Battery or charging warning light
ABS or stability control warning lights
Heavy steering at low speed
Engine stalls or will not restart
Burning smell from the engine bay

What to check

Ask for proof the alternator recall has been done (a dealer invoice or recall record).
Start the car and watch for a battery, ABS or stability control light, and on the test drive check the steering stays light at parking speeds.
Smell for anything hot or electrical in the engine bay after the drive.
If a workshop inspection is possible: run the VIN through a dealer recall check and test the charging voltage under load.

Where to look: Front of the engine, alternator on the accessory belt

Parts involved: Alternator.

Ask the seller

“Has the alternator recall been done, and can I see the paperwork?”
“Has the car ever stalled or shown a battery or ABS warning?”
“Has the alternator been replaced outside the recall?”

OccasionalEngine $600–$2,500 to fix

Does not apply

Like every OM642, the CRD's intake tracts and swirl flaps coke up with an EGR oil-and-soot paste over time, robbing low-rev response, worsening economy and eventually sticking the swirl flaps or their actuator, which brings an engine light and limp mode. It is standard practice to clean the passages and renew the swirl valve whenever the oil cooler is done, because the same teardown exposes both. Short-tripped cars soot up fastest.

Symptoms to notice

Flat low-rev response and worsening fuel economy
Engine light with intake or swirl-flap codes
Rough idle when warm
Black smoke under acceleration

What to check

On the drive, judge low-RPM pull in a high gear — a healthy CRD pulls cleanly from 1,500 rpm; boggy response with black smoke points at a sooted intake. Ask whether the intake was cleaned when (if) the oil cooler seals were done — the jobs share the teardown, and a cooler invoice without intake cleaning means the soot is still there. If a workshop inspection is possible: read swirl-flap actuator position codes and inspect the intake ports with a borescope.

Where to look: Intake manifolds and swirl flaps on both banks, under the engine cover

Parts involved: Intake manifold.

Ask the seller

“Was the intake cleaned when the oil cooler was done?”
“Any engine light history for intake or swirl-flap codes?”
“Is most of its driving short urban trips?”

Body, brakes, suspension & interior2

01Rear Subframe Surface Rust and Bushing Deterioration

2005–2012SuspensionDoes not apply$400–$3,000

OccasionalSuspension $400–$3,000 to fix

Does not apply

LX-platform 300Cs are showing their age underneath: surface rust on the rear subframe is common, and the subframe and differential bushings deteriorate, bringing clunks over bumps and vague, wandering rear-end feel. Heavy scale rust or rotted bushings mean a subframe-out job, which is labour-heavy. Imports that lived near the coast are the worst cases.

Symptoms to notice

Clunks from the rear over bumps
Vague or wandering rear end under acceleration
Visible flaking rust on the rear subframe
Uneven rear tyre wear

What to check

Crouch behind the car with a phone torch and sight along the rear subframe for flaking, scaled rust — surface discolouration is normal at this age, flakes and holes are not. Rock the car and listen for clunks. On the drive, note any rear-end shimmy or clunk over sharp bumps. If a workshop inspection is possible: lever the subframe and diff bushings on a hoist and probe rusted sections for remaining metal.

Where to look: Underneath at the rear — subframe, its four mounting bushings and the diff bushings

Parts involved: Differential.

Ask the seller

“Where has the car lived — coastal or inland?”
“Any suspension bushings replaced?”
“Any clunks from the rear the seller knows about?”

02Front suspension wear - control-arm bushes, ball joints and tie-rods

On the test drive listen for clunks over bumps and feel whether the steering is tight.2005–2012SuspensionDoes not apply$350–$2,000

CommonSuspension $350–$2,000 to fix

Does not apply

The first-gen 300C is a heavy rear-drive car (LX platform, sharing suspension with the Chrysler 300/Dodge Charger), and its front end wears through control-arm bushes, ball joints, sway-bar links and tie-rod ends. Worn parts cause clunks over bumps, vague or wandering steering and uneven tyre wear, and are a common Warrant of Fitness (WOF) failure on older examples. Parts are cheap individually but a full front-end refresh adds up on this large car.

Symptoms to notice

Clunk or knock over bumps
Vague or wandering steering
Uneven front tyre wear
Rattle from the front on rough roads

What to check

On the test drive listen for clunks over bumps and feel whether the steering is tight. Check the front tyres for uneven edge wear. A pre-purchase inspection or WOF check will find worn bushes, ball joints and links. Ask about any recent front-end work.

Where to look: Front suspension control arms, ball joints, sway-bar links and steering tie-rods

Parts involved: Ball joint.

Ask the seller

“Has any front suspension or steering work been done recently?”
“Does it have a current WOF, and were there any advisories?”

Chrysler 300C buyer questions

Is the Chrysler 300C reliable?

Like any used car, it depends on the specific example and its service history. Across the 15 documented faults for the Chrysler 300C, the recurring problem areas are engine, electrical, and transmission. A Chrysler 300C with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.

What are the most common problems with a used Chrysler 300C?

We've catalogued 15 known faults for the Chrysler 300C, covering engine, electrical, and transmission. All 15 are written out in full on this page, with the symptoms to notice, what to inspect, and typical repair costs for each. Free to read, no account needed.

How much do repairs cost on a Chrysler 300C?

Most single repairs on the Chrysler 300C fall between $600–$3,000 at NZ independent-workshop rates. Some of the 15 documented faults cost less and a few cost considerably more, and no one car needs them all. Knowing which ones to look for before you view is what lets you negotiate the price down or walk away.

Should I get a pre-purchase inspection on a Chrysler 300C?

Yes. A Chrysler 300C inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $24.90 far less than the cost of missing one of the faults on this page.
