2005 CHRYSLER 300

Typical onset: 60,000-120,000 mi

Symptoms: Ticking or knocking from engine, especially cold start, Low oil pressure warning light, Sudden loss of power, then complete seizure, Metal shavings in oil on drain

Fix: The 2.7L uses a water-jacketed timing chain that traps sludge, starving bearings and cam journals. Once knocking starts, it's terminal. Requires long block replacement or engine swap. 12-16 hours labor for R&R, plus machine work if rebuilding.

Estimated cost: $3,500-6,500

Typical onset: 80,000-140,000 mi

Symptoms: ATF pooling under vehicle near radiator, Transmission slipping or delayed engagement after leak begins, Low fluid level on dipstick, Pink fluid mixing with coolant if internal cooler fails

Fix: The steel cooler lines rust through at flare fittings and frame contact points. If the internal radiator cooler fails, ATF contaminates coolant and requires trans flush, radiator replacement, and often trans rebuild. External line replacement is 2-3 hours; internal failure adds 8-12 hours for trans service.

Estimated cost: $400-800 for lines alone; $2,500-4,000 if radiator cooler contaminates trans

Typical onset: 70,000-120,000 mi

Symptoms: Clunk or bang on hard acceleration or deceleration, Vibration at idle in Drive, Visible sag or torn rubber on rear trans mount, Exhaust rattle if trans drops too far

Fix: The rear transmission mount deteriorates from heat and age, allowing excessive drivetrain movement. Common on all engines. Replacement requires lifting trans slightly. 1.5-2 hours labor.

Estimated cost: $250-450

Typical onset: 50,000-100,000 mi

Symptoms: Check Engine Light with P0455 or P0456 code (large or small EVAP leak), Fuel smell near rear of vehicle, Hissing sound when removing fuel cap

Fix: Cracked EVAP canister, split hoses, or leaking purge valve are common. Requires smoke test to locate. Canister replacement is 1-1.5 hours; purge valve is 0.5 hour; hoses vary by location.

Estimated cost: $200-600 depending on component

Typical onset: 80,000-120,000 mi

Symptoms: Coolant leak from front of engine, Squealing or grinding noise from accessory belt area, Overheating, especially at idle, Visible coolant seepage at weep hole

Fix: Bearings fail or seals leak. On the HEMI, water pump is behind the timing cover, requiring timing chain access. 3.5L is external. HEMI: 6-8 hours; 3.5L: 2-3 hours.

Estimated cost: $400-700 for 3.5L; $900-1,400 for HEMI

Typical onset: 60,000-100,000 mi

Symptoms: Clunking over bumps, Wandering or vague steering, Uneven tire wear on inside edges, Visible play in ball joint or torn bushings on inspection

Fix: The LX platform eats front suspension bushings, especially in rust-belt states. Most shops replace entire control arms rather than pressing bushings. Both sides typically done together. 3-4 hours labor.

Estimated cost: $600-1,000 both sides

Typical onset: 40,000-80,000 mi

Symptoms: Misfire codes (P0300-P0308), Rough idle and hesitation, Reduced fuel economy, Check Engine Light flashing under load

Fix: Coil-on-plug design. Coils fail from heat cycling; plugs foul or gap widens. Replace misfiring coil and all plugs as a set. V6: 1-1.5 hours; HEMI: 2-3 hours due to intake plenum removal.

Estimated cost: $350-600 for full service

Typical onset: 80,000-130,000 mi

Symptoms: Gear oil drip at front of rear differential, Low fluid level causing whine or howl on decel, Visible seepage on driveshaft yoke

Fix: Pinion seal hardens and leaks. Requires driveshaft removal and seal replacement. Should also inspect pinion bearings for preload. 2-3 hours labor.

Estimated cost: $300-500
