2007 Chevrolet Impala Owner Comments

problem #11

Oct 012015

Impala V6

  • Automatic transmission
  • 80,000 miles


Heater stopped working because the lines were clogged, warranty did not cover it because it was considered contamination. My mechanic said they had to fix many vehicles with this problem, because the antifreeze they use at the factory was bad and clogged the lines. We first replaced the anti freeze and flushed the system which was a temporary fix. The heat went out again the next season and had to replace the heater core and lines.

Impala LTZ 3.9L

  • Automatic transmission
  • 57,500 miles


heater will not come on intermittenly in winter

Chevy service manager said there was a technical bulletin from GM out on this problem back in 20143when it occurred for the first time. In very cold weather, the heater refuses to work properly. Found that out one night at -4 degrees! Apparantly GM is aware of the problem and somehow relates to how the system is plumbed. They did not offer to fix.

Impala LS 3.5L

  • Automatic transmission
  • 51,200 miles


where do i begin with this car. I bought this car in may 2010 with 46000 miles from a local gm dealership with 3mons 3000. the dealership has been very helpfull with this car. in the first 2 months i had to have replaced a front tie rod, rear sway bars, power steering line, wipers motor. august 2010 the keyless entry stopped working, it would only work after you unlock and open the door with the key or after you park it you could lock it, a minute later the keyless entry would not work again. had to have the entire keyless entry system replaced incl key fobs. it was gonna cost 450.00. we talked with the service manger and they fixed it as a good will gesture for the deductible since it was right near the end of the 3 mons. sept 2010 on a chilly sept day i noticed at a stop or idiling the vehicle only blows cold air. my next problem to tackle. i read that most people needed coolant. last night i checked the coolant and noticed it is extremely low. i will be buying some coolant today and see how that works and how long it last. also i was using flex fuel for a few fill ups and was having trouble getting started in the morning. it would take about 4-5 tries to get turned over. i stopped using flex fuel and filled up with regular and she turned over on the first try.

since sept it has been non stop with problem after problem. i fell like my pops back in the 70's with his gm vehicles. i still get an occasional grinding noise on turns in the steering. i figured it was from the leak in the line that was replaced. is it air still in the line??

Heater works fine when the car is moving. However, when it is idle, the air blows cold.

I would lose heat when I came to a light. I added more coolant and it fixed it. I actually had to add 1/4 gallon to get heat.

BLOWN REAR HEADGASKET!!!!!!!!! Take it to the dealer, its covered under the 100,000 mile warranty!

Impala LT 3.5L V6

  • Automatic transmission
  • 40,000 miles

Do not like to complain but GM has a lot of problems with their cars. Do we really need to bail them ou with the quality of workmanship they put into their cars?with the heaters not working when car is not running down the road you could freeze to me this is a bad safety defect.Do they have a recall on this ?

problem #1

Nov 012008

Impala LS V6

  • Automatic transmission
  • 44,500 miles

This 2007 Chevy Impala is only a year old, the heater will not stay warm unless the car remains in motion and/or the RPMs stay above 2,000....I don't understand this.....I don't know what to do to fix this. Other problems with vehicle? Tons....

The sensor in the air pressure tire sensor went out on both rear sides, when braking from high speeds the wheel shakes, no known alignment issues to date, the windows have this annoying squeaking sound when rolled down and MY KEYLESS ENTRY stopped working about a month ago, replaced the battery, reprogrammed device and still nothing........what the hell is wrong with these cars?

Update from Dec 14, 2010: Im now at 67k miles and the car is starting to heat up while in stop and go traffic, basically anytime I stop the temperature gage goes from the middle comfort zone to two lines below the red overheat marks....I don't understand. I just went to get an oil change, they told me the filled my coolant but I am still having issues.....I am out of warranty now and am thinking of trying to buy a different car, this car just isn't worth putting all my money into repairs that shouldn't need to be made so early, the car is only 3 damn years old.....tire sensors are still out, car is heating up, transmission slips and/or timing of gear change is off because the car jumps into gears and even spudders before moving, the windows squeek, the steering wheel whines, the gas cap goes loose randomly, heater does not work unless vehicle is at a steady moving pace, any stops at lights or stop signs and it stops working so I don't have heat, keyless entry hasn't work since March of 08 unless I just get out of the car of if I open the door and close it, then the keyless entry works for like 45 seconds, I could go on and on.....this is ridiculous!

Update from Apr 1, 2011: Okay so somethings have changed....the heater was blowing cold air up until about a month ago. I talked to a mechanic and he replaced my thermostat, seems to be working fine. Tire sensors are still out, there is now a knocking in the dash when the air directionals are changed from defrost to regular air flow (this was doing this since before the thermostat was replaced). Now there is a strange noise coming from the engine upon starting and during regular operation of the vehicle...don't know what it is but the mechanic that replaced the thermostat said that I had an oil leak in my rear head gasget (this means roughly $1200 in repairs).....I don't know how much longer I can keep this vehicle, there are just too many things wrong with it for only being 4 yrs old with 72k miles. However, I got into a car accident recently and the entire rear end of the car was replaced, I don't want to waste a $4000 repair job! What should I do?
