Common Saturn L300 problems
The Saturn L300, a mid-size sedan produced by Saturn, has been reported to have several common problems based on complaints from owners. These issues primarily revolve around the engine cooling system, fuel system, and electrical system.
- Engine Cooling System: One of the most common problems with the Saturn L300 is related to the engine cooling system. This issue can manifest in various ways, such as overheating or leaking coolant. In some cases, the water pump or thermostat may need to be replaced.
- Fuel System: The fuel system in the Saturn L300 has also been a source of frustration for many owners. Issues with the fuel system can lead to problems such as reduced fuel efficiency, difficulty starting the engine, or even stalling while driving. In some instances, the fuel pump or fuel injectors may need to be replaced.
- Electrical System: Electrical system problems are another common issue with the Saturn L300. These problems can range from minor issues, such as malfunctioning interior lights or power windows, to more serious issues, such as failing electrical components in the engine or transmission. In some cases, the body control module, which manages various electrical systems in the car, may need to be replaced.
These problems can lead to significant repair costs, especially as the car ages. In fact, the annual maintenance cost of a Saturn L300 is estimated to be $347 on average, with repair costs varying depending on the age, mileage, location, and shop.
It is worth noting that Saturn, along with Pontiac, was discontinued by GM in 2009, which can make finding replacement parts more difficult.
In summary, the Saturn L300 has several common problems related to the engine cooling system, fuel system, and electrical system. These issues can lead to significant repair costs, especially as the car ages. Additionally, the discontinuation of Saturn and Pontiac by GM may make finding replacement parts more difficult.
What kind of engine does a Saturn L300 have?
The 3-liter, 24-valve V-6 engine in the L300 I tested not only propelled the midsize sedan to run-with-the-pack speed in quick order but also showed the kind of aggressiveness it takes to run with the hotshots.
Why wont my Saturn L300 start?
The most common reasons a Saturn L300 won't start are a dead battery, an alternator problem, or failed starter.
Why is my Saturn L300 speedometer not working?
The most common reasons a Saturn L300 speedometer isn't working are the vehicle speed sensor (VSS), a faulty speedometer, or an electrical issue.

This Saturn has a ride that feels like a heavier car, but its road performance is excellent. It's comfortable to drive, and all controls are within easy reach of the driver. The passenger compartment is quiet and roomy, with a large trunk and good gas mileage. The lumbar control is located to the right side and operated by a twist knob, which could be improved with power control.

I'm glad to hear that you're enjoying your L300 2005! It sounds like it handles well and you're really enjoying driving it. While you mentioned that it could do better on gas and the comfort for back seat passengers isn't great, it's great to hear that you love the car overall. It's always exciting to find a hidden gem like this car. I hope you continue to enjoy it for many years to come!

The best thing about this car is how quickly it can start and how easily it can accelerate to the speed limit from a stop. It's really convenient!

I bought this car two years ago and it has been absolutely the best car I have owned! My wife drove it until about 6 months ago, when we bought her a 2009 Saturn Vue. So, I chose to keep this L300. It's very fun to drive, has lots of power, and still gets an average of 26 MPG. I drive it every day and thoroughly enjoy it. I just wanted to share a quick note: One evening, while going home at around 60 MPH, a deer ran out and hit the side of my L300. I got stopped to see what the damage was, and to my surprise, there was none! There was only one small scratch where the hoof hit. I had no idea this car had composite panels on the doors. Why don't all vehicles have this? I can't say enough good things to describe this car!

After researching and test driving several luxury wagons, we finally found the perfect fit for our family of four - the Saturn wagon! This vehicle has plenty of power and features butter-soft leather seats that make for a very comfortable ride. With standard side curtain airbags, a spacious cargo area, and plenty of legroom for all passengers, this wagon is both practical and luxurious. The 6-speaker stereo system is crisp and thumping, providing an enjoyable audio experience. While there is some road noise, it's not as noticeable as in the BMW wagon, and the Saturn wagon comes at a much more affordable price point. According to a Saturn representative, the L300 model wasn't marketed well, which resulted in poor sales and eventual discontinuation in 2005. However, we are extremely satisfied with our purchase and feel that we got a great deal on a luxurious vehicle.

The L series Saturn was not a great choice, especially with the dimming headlights and dashlights that could be mistaken for signals on the highway. However, it is important to note that the flickering of the headlamps and/or instrument panel lighting is a normal characteristic due to transient current loads on the electrical system during normal vehicle operation, as stated in the TSB (technical service bulletin). It is also worth mentioning that the 4cyl in the L series is weaker compared to the SL2, despite being a bigger car with the same engine size.

Hey there! When you're looking to buy a car, it's important to consider your needs rather than just your emotions.

We purchased this car at 100,000 miles for $3200 and have since put 27k miles on it. While we initially thought we got a great deal, we've unfortunately had a few issues with it. We had to replace the tires and the keyless entry remote, as well as the battery. Additionally, the CD player and radio buttons are broken. We experienced a breakdown when the fuel pump went out, which cost $600 to replace. The A/C also stopped working, and we had to replace the rear brakes twice due to a caliper locking up. Recently, we've noticed some flickering with the dash and headlights, which we were told is due to the alternator. Yesterday, the engine light came on and the code indicated an issue with the O2 detector. We're hoping to get this resolved soon.
