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.

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.

9/29/2006 I purchased a used 2005 Chevrolet Impala from mission automotive and an Eagle warranty. On 1/31/2008 the car had a "coolant" problem or over-heat problem of which I took it immediately to the certified Chevy. Dealer. Eagle warranty sent an agent to look at the car after I paid $600 to have it torn down. I also incurred a rental car during this time. The problem was diagnosed by the Chevy dealer as an "engine coolant" problem. The agent from the warranty concurred and would not pay for anything. I have that report. The chef 2005 Impala operators book states the cooling system in your vehicle is filled with dex-cool engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles, whichever occurs first. My car was purchased with 84,460 miles, the defect occurred at 96,542 miles.

  • Automatic transmission
  • 64,480 miles
The contact owns a 2005 Chevrolet Impala. The following day after the vehicle was purchased, the speedometer stopped working. A cluster was repaired and a new steering column was installed at the cost of $465. After the cluster was replaced, the speedometer began to work. While driving between 55-70 mph, the vehicle began making a whining sound. The whining sound could also be heard while driving at speeds between 35-45 mph. On four occasions, the vehicle would not defrost and heat up at temperatures between 45-59 degrees. The dealer stated that nothing could be done. On three different occasions, the vehicle stalled. While parked at a gas station and twice when attempting to start the vehicle, it eventually restarted. The dealer initially stated that the failure could be due to the ignition or the starter. The contact found a nail in a tire and went to a tire shop. She was informed that all four of the tires had cracks on the edge of the tread and were dry rotted. The current mileage was 65,480 and failure mileage was 64,480.

I have a 2005 Chevy Impala, currently with 22,320 miles. At my oil change and tire rotation, (~20,500) I was informed by repair place that they would not perform the tire rotation as I would be needing to replace the tires soon. I asked why they were wearing so fast- I was told, they noticed it on many Impala- premature tire wear between 18,000-25,000 miles. ~ 15 months ago, with only about 13,000 miles, when I had an oil change done I was informed me the engine was leaking oil from the rear of the engine, I should take it to the dealer for repair. The dealer had to replace (under warranty) several seals/gaskets- oil pan, drain plug, oil filter, plus replace the drain plug. The car is sometimes hard to start and have to hold the key in the start position, and/or lightly press the gas pedal to start it. About two weeks ago, I grinded the starter. Sometimes the car will start roughly and immediately stall, or will stall the first few seconds as I am backing out the drive way. Dealer about this they told me I was using cheap gas and to use a better brand, but I always use "brand" gas, I even use fuel injector cleaner dealer later told me I needed to have the fuel injection "flushed" with their system for $199, plus tax and charges, hearing it was not good for the vehicle, I declined. I have also noticed a "clunking/bumping/banging" noise when turning, especially hard turns. My brakes need to be replaced, the front brakes are starting to make a thump when braking, and yesterday when braking hard, I heard a squeal noise, (rear?). fuel gauge sometimes rapidly fluctuates, when driving, and at times when accelerating, (though not concurrent) I hear a "swoosh/gargling" sound. I was accelerating too hard. The fuel gauge will swing as much as a 1/4 tank when driving before recovering to the correct position. Gauge shows low fuel level, low fuel light comes on, I only needed 10-12 gals to fill it (~16 gals).
