The cooling overheat light went on and the car turned off on me and my child on the exit of the 170 fwy, it now makes a screeching sound like metal, the radiator leaks and something smells burned, the mechanic I went to that was close by said I have to now replace the engine and other expensive items that seem to fall under the 2001 Impala recalls, my fuel pump has an issue as well and the electrical problem even worse it turns of and on as it pleases.

My vehicle recently started having issues with overheating. As soon as it would warm up the gauge would go the whole way past the hottest possible temp on the dash. My hot coolant temp light would come on and then I would have to pull over and turn the car off to let it cool. I took it to a mechanic who said that I would have to replace the head gaskets and intake gaskets. He researched it and said that he found that Impalas from 20003-2007 had problems with the engines because of an additive that was put in the engine. I paid him over 1000 dollars to fix the issue because before I took it to him I took it to a different mechanic who said it was the radiator so I got that fixed which cost me close to 500 dollars. So even after I got both of these problems fixed my car still overheats.

Passlock system would disable the car from starting dozens of times for months. I would get stuck anywhere without warning for half an hour or more with my children. It was taken in for a coolant leak issue. The dexcool ( a horrible product with lawsuits due to engine damage) had eaten the hoses and was spraying around the engine. It created a sludge that thankfully did not destroy my radiator. The car finally outright failed because of the security system. The passlock system is a known issue with gm. I have read endless complaints about this problem. There was nothing wrong with the car, but the system would not read the key. It was in the shop for weeks. Had to get new bcm and have the system reprogrammed. My car only has 37,000 miles and for it to fail and need such expensive repairs for a faulty system with nothing wrong with the mechanics of the car is unreal. Another known issue is with the signals going out without warning. I never know if the turn signals will work and this is very dangerous. I am fearful that other issues with the electrical system might happen. But knowing that the bcm might fail again in another year or so is the biggest rub. How many times do people have to reprogram their car and replace parts on a faulty passlock system that will fail again?.

Failure Date: 12/21/2012

First. . . My car all of the sudden started leaking like an oil tanker last January 2012, and the abs/traction control lights came on. Took the car to the chevy dealership, and had major repair work done on transmission, and engine for leaks. Spent $2100 and was quote $2600 to replace the abs/traction control modulator for my abs/traction control to work again. The code they pulled was c1218. Needless to say it has not been repaired yet. A month after spending this money, I had to replace the water pump, and almost a year later I had to replace a plastic elbow from the water pump to my radiator which was another $300. Then this past December 2012, my transmission all of the sudden jerked hard from 1st to 2nd and so on during local driving. Max speed limit is 40mph locally. Took it to chevy and was told I need a new transmission, so I took it for a second opinion and was told code p1811 was coded for a long shift, but that my transmission was a 1/2 quart low so they filled it with trans additive. They suggested I try a "transmission shop" for them to check because maybe my trans solenoid was bad, which would still cost quite a bit for repair, but not nearly as much as a new transmission. My car has 122,000 long highway miles, not local; stop & go. I do not feel my abs/traction control, nor my trans should be bad. I maintain my car, and based on my internet searches many people have had the exact same problems with these cars. I emailed chevy and was basically told this is my problem and no concession was offered on their part to assist me with these repairs. I have been laid off from my job, and returned to school so needless to say cannot afford a new car, but this car is costing more than it is worth. Chevy needs to quit ignoring these problems, and take care of loyal customers before they lose them.

While driving my 07' chevy Impala the temperature gauge arm often will drop to 'c' as if the engine temperature is cold, then the drivers information display panel will display a message "engine hot turn off a/c". I've had the thermostat replaced, radiator coolant drained and replaced, hoping to fix this problem, but I'm still dealing with it. After doing some research I'm finding that there has been other chevy vehicle owners dealing with this same issue, which is most likely a bad 'engine coolant temperature sensor (ect).

Failure Date: 11/04/2011

I purchased a car from icarsnow (704-551-0990) on south blvd in charlotte on October 28, 2011. I drove the car for a week when the gears started slipping and the car started to stall and jerk the car had a 90 day warranty so I called southern warranty (704-282-1814) and they had me to take the car to carson automotive 10940 a e. Independence blvd. Matthews nc they replaced the transmission and converter on 11/4/11. I picked the car up drove for a week or two and the car was still stalling and jerking. I called carson automotive and took the car back. . I also heard a noise in the engine. I took the car back to carson automotive they could not find why the car was stalling and jerking but the said the engine needed to be replaced because of a rod the engine was replaced on 12/27/11. That is when I found out that the 90 day warranty was 50/50 where if anything major happen to the car the warranty company would pay have and I would have to pay half. This is not how it was explained by the salesman at icarsnow. He told me after the 90 day warranty if anything happens major that the warranty company and I would share the cost. In order for me to not loose the money already paid on the car I have to pay half on the engine. After the engine was replaced the car was leaking anti- freeze I took the car back again carson automotive could not find anything. The rear window replaced because the defrost was not attached and sparked when you touched it. There was also a leak in the trunk that had to be repaired. After that the temperature gauge started to move up I took the car to my mechanic for him to check it out on 2/25/12. The problem was possible head gasket damage. I took the car back to carson automotive since they put the engine in. They told me that it was not the engine but a cracked radiator. Radiator was replaced on 2/27/12.

The traction control turns on frequently. This causes the car to make a grinding noise. When braking the car makes a grinding noise and car is not stopping it feels like it's locking up and sliding. In a sudden stop needing to be made is at great risk of a accident. I have replaced a elbow shaped part that has busted open twice. Car is constantly over heating the radiator cap has a rustic clay like substance. It won't hold antifreeze, I don't see a leak but it needs refilled quite often. The engine smokes, the cars rpm's will flex up and down and the car will just cut off. I'm wondering if the rustic clay like substance has gone through my engine and is causing me many problems with it. I have found reports of lawsuits in past regarding dexicool in gm cars doing this and ruining the engine. The problems in the reports are just like mine and many others on here. Help!!'.

I noticed a couple of times in stop and go traffic that my temperature indicator started to inch its way over to hot, never reaching the mark. I told my husband and he said I probably need a flush and new coolant. Took the car to dealership and I had a leaking intake gasket and needed to be repaired. Very expensive! had oil in the radiator with hardly any liquid left. I started to read about other complaints and there were several so decided to report this so others will know they are not alone.

I have only had my car for 9 months and have had trouble from the beginning, the heater will not heat up and when it does it goes cold unless you are pressing the gas and will not defrost and it keeps losing fluid so they replace the radiator cap. It has a bad shimmy and a popping in the steering wheel it has less then 45,000 I really think they need to check in on all the problems people are having with the 2006 Impala.

The lower intake manifold gasket leaked twice within 45,000 miles, had to have vehicle serviced twice for this intake issue, which involved missing work. Bad enough I can't afford the repairs, but then I have to miss work as well. Low coolant light comes on constantly and vehicle over heats. I have had the transmission replaced, radiator replaced, water pump replaced and haven't only owned the care for 3 years. I am rebuilding the entire car! I've owned 7 chevy cars but none as bad as this. I will never,ever,ever buy another chevy.

Engine coolant light would not go out after I had radiator flushed. Took the car back to the mechanic and was informed that there was some brown, muddy looking, oily substance leaking into the radiator at which time he informed me of the problem that gm cars were having with the manifold gaskets. This is an outrage and there needs to be a recall on this problem before a death does occur due to this negligence on gm's part. I'm sure that all the owner of these cars feel the same way and that the manufacturer should be liable and ordered to pay to have these cars repaired, since it is such a widespread problem, which they apparently knew would happen after the car had been driven to a certain mileage. I also had a problem about 3 years ago when the car would not stop when I was driving it. The cruise control module got stuck and the car continued to accelerate unless the brakes were applied. And even then the engine continued to rev very high! I was in fear of my life. . . . And luckily I made it to the dealer without having an accident. These Impalas are death traps and I think that there have been deaths that have not been explained due to the same problem that I had with the acceleration module. Unfortunately. . . Dead people can't tell what happened to their cars before they lost control of them.

One day it just got warm. We turned it off and the radiator bubbled. I let it cooled down. I checked the oil and water. It was probably a quart low and the oil looked a touch milky. Oil was not over full. I assumed it was fine. The next trip to town and back(about 20 miles round trip)it ran warm on the way home. When we got home the radiator was boiling a little bit again. After it cooled off I checked the water is half to three quarters gallon low on water. Oil was registering a little more than a quart over full and real milky looking. That is when I noticed there was a problem. I change oil and filter. Topped off water. I added some aluminum seal and topped off the water. After I did that it seemed like it was fixed for about 8 days then it did it again. I haven't started it or driven it since. It is going to cost about 500-800 dollars to get it fixed. My complaint is that general motors knows about the intake manifold gasket problem but they won't recall any of these vehicles. There is even a petition online to get them to. My car is a 2000 Chevrolet Impala. I didn't feel like I should have to pay for their mistake. I can't afford to get it fixed and I am still making payments on it. I didn't want it to go to waste it is a very nice car. I really like my car. I wish I could drive it.

While driving on the freeway I have noticed that me steering wheel became very stiff and smoke started to come out from the hood. I drove the car home slowly, and the next day taken it to the chevy dealership. My engine was blown due to the lower intake manifold gasket (which already had been replaced) and the head gasket was blown. I had to replace a brand new engine. ($4k). Next my transmission was completely done, and I had to replace that. The radiator was messed up and had to replace that as well as the starter. The airbag light will not go off at all either. Now I can not get my car smogged due to the check engine light which the codes came up as "too lean on bank 1" which could mean a variety of things according to the mechanic. Today while I was driving my car to work there was smoke coming from the steering wheel column which smelled like burnt plastic. Oh. . . How could I forget a few months back my car just wouldn't start out of nowhere and the mechanic had to replace the sensors as well. Oh another problem is the steering on the car is so stiff as if I don't have power steering. All the money I have invested in this vehicle I could be driving around a mercedes!.

Only 78000 miles on my 2002 Impala when the coolant light comes on. Nearly $1000. 00 later they told me I needed a new water pump, intake manifold gasket, belt, radiator cap, thermostat and of course an oil change. All of this because the coolant gm requires is corrosive and causes the above items to deteriorate. How long will the replacements last? not sure I want to find out.

2002 chevy Impala 3. 4l 84,000+ miles low coolant light comes on. Leaking antifreeze but not sure where. Continually having to add antifreeze to overflow to maintain level. Car smells like burning antifreeze after being driven. Numerous complaints found online at car forums with other consumers having the same trouble. Contents in radiator and overflow is thick, oily-like substance. So far, while checking oil, it is ok. Not milky or cloudy. Numerous reasons why vehicle has coolant problems. One theory is dexcool causes the sludge. Another theory is faulty intake valve & gasket. Main theory is problem originates from intake valve (gasket) and dominos.
