Saturn LS2 Problems
The LS2 was introduced in 2000 as part of the L-series by General Motors' subsidiary Saturn. The series was intended to be a good line of midsized coupes and station wagons, but poor sales caused GM to cancel the whole series. The negative response proved to be too much for GM, especially considering that the LS2 sedans were the company's first attempt to move to midsized cars. Among the issues commonly raised against the LS2 are listed below.
The most common problem with the LS2 is its engine. If you have an LS2, you should have experienced a time when the engine suddenly turned off. After driving the car for some time, or for a few thousand miles, engine failures become a normal thing. The problem gets worse if it's left unattended; the engine may turn off more than twice during a drive. In particular, engine failures are usually observed in LS2 sedans that use the 2.2L engine. This problem even caused the North Carolina Consumers Council to petition an investigation against the defective design. A quick look at the engine assembly showed that the failures are caused by a faulty timing chain design.
Brake and taillight failures
Another wrong move made by Saturn is the use of plastic terminal covers on the electrical connections. These covers can get caught easily in contact surfaces which would then lead to an insulated connection. The usual manifestations of this are brake and taillight failures (either the lights won't go on or the light is too dim).
This issue led to a recall, affecting more than 300,000 vehicles in the US and Canada, demanded by the North Carolina Consumers Council.
Check engine light issues
In an interesting mix of problems, the check engine light presented issues of its own. Since the LS2 had faulty electrical connections AND is very prone to engine failures, one will not know what the problem is when the check engine light turns on.
Since the light can go on because of either factor, LS2 owners get confused as to how to solve the problem. Most often, this causes the owner to just check everything which can be very costly and time-consuming.
How to Prevent your Saturn LS2 from Breaking Down
Your Saturn LS2 is one of the most reliable, roomy, and comfortable mid-sized sedans ever built. It's easy to understand why you acquired one. However, no matter how durable your car may be built, there will come a time that you will experience problems with it. In fact, it is inevitable. The best thing that you can do is to come prepared. Arm yourself with these maintenance tips so you can prevent future problems and prolong the life of your Saturn LS2.
- Prevent engine oil from leaking.
One of the most common car problems is oil leak—even if it is minor, it is still a threat to the engine as it can cause the engine to break down. This is why you should not take leaks lightly. When you notice oil is leaking from your engine, you must have it checked immediately. It can be hard to diagnose where the oil leak is coming from if you don't have the proper background, so bringing it to your local mechanic would be a smart move. However, you don't have to wait for it to happen to you. You can always do preventive maintenance.
There are several components that should be checked regularly to prevent oil leaks, and one of them is the oil filter. Oil filters get filled with dirt and small debris that can clog it. If the oil filter is clogged, the oil will find another way out of the filter, so make sure you change the oil filter regularly. Another component that should be checked is the oil drain plug. If it gets worn out or comes loose, oil can leak from it. And then there's the oil filler cap. If it is worn out, loose, or missing, the pressure of the engine can cause the engine oil to spill while the engine is operating. The valve gasket should also be kept an eye on since a worn-out valve gasket is probably the most common cause of oil leaks.
- Prevent rough or no-start problems from happening.
It can be very frustrating if your car won't start. This is why you should keep tabs on the parts that are involved in starting your vehicle. There is a myriad of car parts that helps in starting up your vehicle, so it can be quite frustrating to determine which part is causing the problem.
In keeping tabs with your ignition system, start with the fuse. Check if it is broken or busted. Once you are done checking it, work your way to the battery. Problems with the ignition can be caused by a simple blockage on the battery ports. Over time, it can get blocked with dirt and corrosion, so make sure you keep it clean, always. A dead battery is also a common culprit of no-start problems. Measure the power inside your battery with a battery tester from time to time. The battery tester will tell you if you already need to charge the battery or if you need to replace it entirely. Then try checking the ignition switch. A faulty ignition switch can also cause your car not to start.
