Is the Chrysler 300C reliable?
The Chrysler 300C has 3 known faults in our database, 2 of them rated high severity. The most serious are safety (DVSA recall R/2017/174 (June 2017, 9,837 vehicles built from 5 February 2004 to 12 July) and electrics (DVSA recall R/2015/200 (December 2015, 2,481 vehicles built from 10 January 2007 to 12). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
Which Chrysler 300C years should you avoid?
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.

Chrysler 300C Mk1 (2005 to 2010) problems
Engine/EmissionsMedium severity📝 Editorial
On the 3.0 CRD diesel the electronic throttle warning light comes on, closely followed by the engine management light, and the engine drops into limp-home mode. The archive traces it to the turbo swirl actuator and the boost control regulator, a problem shared with the Mercedes E 320 CDI, and Chrysler UK issued a service bulletin telling dealers to repair the swirl flap motors free. A 30,000-mile 2010 300C Touring bought from a Chrysler dealer in 2014 had its swirl flap motor fail and damage a turbo pipe, with the repair estimated at £900, because the bulletin work had not been done.

Safety SystemsHigh severity🏛️ Official recall
DVSA recall R/2017/174 (June 2017, 9,837 vehicles built from 5 February 2004 to 12 July 2012): moisture getting past faulty seals is absorbed by the propellant in the front airbag inflator, so when the airbag deploys excessive pressure may rupture the inflator body and send metal fragments through the cushion, injuring occupants and in the worst case killing them. The free fix replaces the airbag module with its inflator. DVSA's record names the driver's airbag in its concern line and the passenger's in its remedy; the archive calls it the front passenger airbag.
Rough guide

ElectricalHigh severity🏛️ Official recall
DVSA recall R/2015/200 (December 2015, 2,481 vehicles built from 10 January 2007 to 12 May 2008): the wireless ignition node can stick between START and RUN and then spring back to OFF or ACCESSORY while the car is moving, cutting engine power, power steering and brake servo assistance and some electrical features. The free fix replaces the ignition node and the key fobs. The archive carried the US version of this recall in 2014, which adds that the airbags lose power too.

Which Chrysler 300C years should I avoid?
No Chrysler 300C year is a write-off, but the Mk1 (2005 to 2010) carries the most serious faults: safety and electrics. Year matters less than whether the specific car has had the known fixes, so check the history for them.
What should I check when viewing a used Chrysler 300C?
Ask the seller about the safety, electrics and engine faults on this page and whether they have been fixed, with invoices. On the test drive watch for no symptoms until the airbag deploys, engine cuts out while driving and electronic throttle warning light followed by the engine management light. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against all 3 known faults before you travel. Check a Chrysler 300C advert →

Owners report 30.5 mpg on average across the Chrysler 300C engines with data, about 92% of the official combined figure.
