Check engine light came on and security light started to blink when we got back from a trip. We took it in and the diagnostic check revealed that the knock sensor was bad. So that was replaced. (code 00327). *ak but now the light still keeps coming on for the same code even though it's already been fixed.

My car's coolant light came on the first time about 2 weeks ago. At that time I replaced the coolant that was missing, only to have the light come on again 2 days later. I again replaced the coolant. I could not find any visible leaks under the car. I was driving to the mechanic when my check engine light came on, and the check coolant light came on. The cars tempature gauge was topped out. I had to pull over to the side of a major freeway and call for help. After 2 hours of waiting for a tow truck. The mechanic tells me that the upper and lower intake manifold gaskets need replaced. Also, the coolant had leaked into my engine and mixed with the oil causing the engine to miss. I had to have the gaskets replaced with a new version. And also have the engine flushed, an oil change and a coolant flush as well as a coolant change. All of this costing well over $700. Apparently, gm has issued a service bulletin related to this issue but has failed to issue a recall on that particular part. My safety should be of some concern to this car manufactuer to say the least!

At 50k miles, low coolant light would flicker on and off so per the manual dexcool/water mixture was added. This alleviated the problem only temporarily however. Light continued to come on, and later at 61k, oil leak was noticed on the side of the intake manifold. An appointment was made to bring the car to the dealership the same week, during which the security dummy light came on (for no apparent reason). Also during this week, the "change oil" dummy light came on 100 miles before the oil change was due (at 2900 miles). The car was brought to the dealership to fix per its appointment, and not only was coolant leaking into the engine, but the upper and lower intake manifold gaskets required replacement. In addition, on its way to the dealership, the engine started to misfire causing the "check engine" light to flash for several moments before turning to a steadily lit dummy light. Car has always been given routine maintenance and oil changes every 3k or as necessary, so this performance and obvious design flaw are very disappointing. Would not recommend this car/3.4l v6 engine to anyone looking to purchase a new vehicle and considering this make/model/engine type.

I bought my alero in may of 2003, and it is not march 2004 and I am replacing the motor. Started out with brake problems, then went on to the leather under the windows and on the dash "bubbling" up in the sun. Next, I had coolant/oil leaks at the intake manifold. Low trac light came on all the time, low tire pressure light stays on, the fan for the A/C or heat only worked in the 3-5 positions. (it's full blast or nothing.) coolant light frequently came on, transmission fluid vanishes, coolant leaks, yet no one knows where from. The temperature gauge never goes below halfway, and it ran hot a lot. Had to replace the coolant cap and overflow resevoir. The gas hand sticks, the speedometer sticks, the leather seats are tearing, had to replace the factory radio because it would not pick up any channels, rear defrost works only when it wants to, and service engine light stayed on about half the time. I took this car to 7 mechanics, had it hooked up to diagnostic computers, had everything checked-yet no one could tell me what was going on. Finally, I left the mechanic shop after being told that the car was "good to go" (which I would never put in the same sentence with alero again.), and it starting skipping. I had it towed, only to find out that I had a cracked block and cracked heads. (new motor needed-final prognosis) my mechanic told me that it would do absolutely no good to put a motor in it because in 2 years-the new motor will do the same! Oldsmobile should be ashamed that they would recall a glove box latch, yet not the motor. After reading the reviews that I have read in the past week, I am seeking legal action in regards to this issue. I did not pay $17,000 for a lemon, which is all I got!! Don't buy!! Buyer beware!!

The check engine light came on. Upon checking the coolant levels, it was low. The repair shop diagnosis is a leak in the intake manifold with an $800+ repair cost. According to research, the particular type of coolant, dexcool, used in gm cars is linked to corrosion to the intake manifold gaskets.

The "coolant" light came on - then the car died & overheated...apparently coolant was leaking into the engine because a gasket failed...now the engine must be replaced at 70,000 miles. Starting at 3,000 miles, the check engine soon light came on & it has been in and out of dealerships ever since!!! Gm hasn't done a thing to help me! I just spent $1,300 to get the gasket replaced in the intake manifold & now they tell me the engine needs to be replaced!!! Please help me - I need a contact for gm - the customer service line has not done a thing to help & apparently this is a common problem...

The front brakes and rotors have been replaced twice. The brakes are vibrating again when you try to stop at a higher rate of speed. The check engine light and service engine soon have been on at least 6 times. The fuel injectors have had to be replaced 4 times.
