Specs side by side
What owners say
300M
Overall
Sentiment is sharply divided and heavily dependent on individual vehicle history and maintenance. A subset of long-term owners report achieving high mileage (275,000-300,000 miles) with the 3.5L V6 engine described as "super solid and very reliable when maintained," praising the car's comfortable ride, spacious interior, and powerful feel for its era. However, the dominant narrative from buyer experiences centers on poor long-term reliability and pervasive, expensive failures.
Best version to buy
Insufficient owner data available to designate a "best" version. The "300M Special" trim is mentioned in the context of specific wheel sizes (18") and potential collector or parts value, but no consensus on superiority is formed.
Known issues
- ⚠Electrical system failures: pervasive "gremlins" including interior/exterior lights malfunctioning on their own, power accessory failures (locks, windows, seats), no-start conditions, sensor failures, and complex computer/ECM issues.
- ⚠Cooling system problems: chronic overheating, coolant leaks, boiling coolant, leading to potential engine seizure. Thermostat housing issues are specifically mentioned. Frequency: very frequent.
- ⚠Automatic transmission failures: slippage, failure to engage, dropping into neutral, fluid leaks, and general lack of reliability. Frequency: very frequent.
LHS
Overall
Sentiment is mixed and heavily dependent on specific model years and maintenance history. The vehicle is consistently praised for its comfort, with multiple owners describing the driving experience as akin to "driving a leather couch," and appreciating its spacious, refined, and elegant design for the era. The 3.5L V6 engine is noted for being a "fairly high output" and "robust" powerplant, with one owner stating their 2001 model was "flawless." However, a very strong and recurrent criticism centers on catastrophic automatic transmission failures, particularly in early models (noted as 1994-1995).
Best version to buy
The 2001 model year is implicitly recommended based on a specific owner report of flawless ownership, contrasting with severe transmission issues reported in earlier models like the 1995 and 1996. The data suggests later production years benefited from revisions that addressed some of the early transmission problems.
Known issues
- ⚠Automatic transmission failure: Catastrophic failures reported, particularly in early models (1994-1995); described as a fundamental design flaw with the "Ultra drive" (42LE, etc.) transmissions. Frequency: very frequent.
- ⚠Electrical system failures: Various gremlins including security system malfunctions preventing starting, faulty oxygen sensors causing the car to enter a "dead" mode, and general electronic component failures as the vehicle ages.
- ⚠Cooling system problems: Overheating issues, potentially related to water pump failure, thermostat issues, or head gasket concerns on the 3.5L V6. Frequency: recurrent.
The verdict
The Chrysler LHS is the better choice for most buyers.
It has more power on its best-equipped version than the Chrysler 300M, based on the data above. If efficiency matters more to you than outright power, the Chrysler 300M is worth a closer look instead.
