 On march 14, 2013, we were accelerating from a complete stop when the service engine light came on and a message appeared in the message console that read engine power reduced. it was difficult to get the vehicle to accelerate at first, but it then responded after a few seconds. the 'service engine light stayed on. we took it to an automobile parts store so they could pull the code with a code reader. the vehicle parts store was able to pull a code reading p2138 which is for the throttle position sensor. later on that night, i went online and did some research and discovered that there are many owners of 2008 chevy impalas with the same problem. in the past year, there have been several occasions when my 2008 chevy impala tends to buckle and jerk or hesitate when accelerating from a complete stop making difficult to nearly impossible to navigate out of the way of traffic. is there any way a recall can be issued for the throttle position sensor and the gas pedal so this issue can be resolve for all owners of 2008 chevrolet impalas? please help.

 The right rear door lock works intermittenly with my power door lock system on my 2008 chevy impala. also the right front passenger door lock worked intermittenly at first and now it does not respond. i have done some research online and i know i am not the only owner of a 2008 chevrolet impala with this problem. pleas help. is there any way a recall can be issued to get this issue fixed? it is impossible to unlock the right rear door from the outside with a key because there is no key hole. there is only one key hole on to unlock a door with the car key and it is on the driver side door only.

 Gear shift stuck in park position. would not shift into any other position. chevrolet mechanic found electrical problem and made following comments on the repair order. found that shift lock control solenoid inop. found that green wire melted about 12 inches from shifter and also connector for shift lock control had high resistance.. repair commented: replaced connector and repaired wire working as designed at this time. mechanic stated that this was not uncommon. also found numerous internet forum comments about this problem.. very serious fire hazard. gm seems to be aware since above repair implies a reworking design of wire working.: evidence of burned wire inside a vehicle should be considered a serious fire hazard.

 2008 chevy impala. right rear door lock began working intermittently. right front followed suit shortly afterwards. now, some 5 months later, the driver door is behaving the same way. it makes transporting my children difficult and unsafe. if there were to be an accident, the children in the back seat are not likely to have the mental capacity to remember to unlock the door which could lead to further injury or death. wiring harness in the center console is poorly designed and located in such a way that the wiring breaks and making it so electrical safety devices do not disengage thus not letting the key be removed, the vehicle not being able to shift from park, and other failures yet to be identified.

 I was driving on the highway leading into an overpass. as l entered onto the overpass my service traction control, engine power reduced, and service throttle body disabled flash across my dash board, killing the power to my vehicle and locking my steering wheel. while i was stopped unable to move my vehicle, cars flew me and i was almost hit. at one point another vehicle was almost ran off the road due to oncoming traffic trying to dodge me. this was the worst experience of my life. i have never feared for my life like i did at this time. after doing my research online, i have found many others have been in my situation. i was told that my accelerator pedal sensor has gone bad. i feel that gm should be held responsible and needs to remedy the situation before someone is killed.

 Key gets stuck in ignition and will not turn to lock position. the battery runs down after sitting for awhile. i googled complaints of this happening and there were hundreds of complaints. the problem lies in the center console of automatic transmission cars. chevrolet designed the wiring harness to drag across the floor while moving the shifter lever from gear to gear. this eventually causes the wires to break. depending on which of the five wires break causes problems with the ignition switch (car won't start, transmission won't shift, steering wheel won't lock, key won't come out are some of the problems). as i stated there are hundreds of complaints and feel to issue a recall by chevrolet would be inline. *tr

 I purchased my '08 impala lt used, vehicle was in perfect condition, older owner and was a seasonal vehicle as we live in south florida this owner was a snow bird and only used the vehicle 4 months out of the year. i had the car about 7 months and then i noticed a problem with the locks, they would sometimes not lock/or unlock while using the fob, the interior lock still worked for a few more months and then everything eventually ceased. now nothing works, unless you manually lock/unlock it yourself. problem is.....i have children, small children and when doing 8 other things while getting out of the car, or parking the car and getting out it is such a pain in the a** that i have to go through this with a somewhat newer vehicle!!! i tried replacing the fuse, that didn't work. i can hear the locks click, but nothing happens. well.....i had some work done to the vehicle, new tires and an alignment and had them look into it further, they did and told me the actuators need to be replaced, $1200!!! i almost passed out right there!! for something that was not the direct cause by me how irresponsible of chevrolet to allow these parts to go bad, i did a great amount of research and found this problem with quite a few owners of this very same vehicle, this and the air flow thing that makes a horrible noise, like banging!!! that will be my next complaint!! i found that apparently, the grease from one of the components that is next to actuator is eating away at the part causing it to default!! chevy needs to have this recalled, asap!!! people with small children, who keep them in the back seat could have some serious problems if they are unable to get to their kids.....especially since the locks are all the way towards the rear of the door you cant even reach it from the front seat. this is supposed to me considered a full size sedan, a family car!!! *tr

 The left rear door actuator failed and the remote opener and the driver's and passenger's electric locks would not open or lock the left rear door from the inside. i was advised by local gm dealer that this problem does not constitute a safety recall, even though it involved passengers who would be riding in the back seat of the vehicle. *tr

 Power door locks stopped working. i can open the drivers door with the key, but the other power locks do not open. it started with the rear locks and now includes all locks. this is dangerous because we carry our small grandchildren in their car seats in the back. the only way to unlock the doors is to roll down the power window and reach in to unlock. i have discussed this with chevrolet but they say they have no reports of others having this problem. this is hard to believe since there are so many reports of this on the internet forums. i believe this is a very serious safety issue. in an accident, the rear windows may not function and we would have to break out the rear windows to free our grandchildren. *tr

 Both rear power door locks have failed. they are inoperable from inside the vehicle. this has caused an unsafe condition for the passengers in the rear seats of the vehicle. this in a very common problem with the 2008 impalas. chevrolet is aware of the issue, but has not started a recall to address the issue. *tr

 I was traveling on a highway near to my home, and for about a month now the vehicle has come up with an error stating reduced engine power. suddenly, the vehicle simply stalled itself, coming up with a message that stated starting disabled/service throttle. i was traveling uphill at 40mph, now with no power brakes, no power steering, and the engine completely shut off and unable to restart. luckily i was able to pull over and disconnect the battery and reconnect it to restart it. what if this had happened on a highway on or off ramp? or on a corner? or with a vehicle traveling behind me? i believe any vehicle that will just randomly turn itself off due to a part that has had hundreds of complaints that i've just read online is unsafe to be driven on america's highways. i read online that this was a prevalent problem with these vehicles, and i hope i get injured because of it so i can sue gm.

 The rear door locks will not operate via the electrical. this i believe causes a hazard for a rear seat passenger especially an infant or young child. they could be trapped by the in-ability of the driver to activate the rear door locks to evacuate the rear seat passengers in an emergency.

 Failure of power door locks. this is a safety issue. in order to keep the vehicle secure, the doors must be locked. if a child, infant or disabled person would be in the back seat and needed to get out in an emergency, the door cannot be opened from the outside without someone first climbing through the seats from the front and reaching way back to the back of the door to unlock it manually or breaking the window. this takes time and could result in serious injury or death to a passenger. this problem is known by gm as they have made modification to the part for the rear driver side door but have not yet modified the part for the rear passenger door. some drivers are now reporting that the front doors are also affected by this defect. each part is approximately $175.00 or $700 for all doors affected and probably that much again in labor costs. other complaints and incidents can be found by searching the subject on the internet.

 For a few days i have been smelling a burning smell in my car. i noticed that my rear window defroster had stopped functioning. after a google search i came up on a posting at the naioa website with many people having a connection burn up in the passenger kick panel with pictures posted. i went and looked at my car and the connector was burnt and melted just like everyone elses in the forum posting. this is a connector with many wires in it, and i think could be a fire hazard or safety hazard on the vehicle if the other wires burned or shorted.

 All 4 door lock actuator have gone out, within a month of each other, was told that this was caused by wear and tear of the vehicle, after 3 years this should not happen, after dealing with gm for over a week, they are willing to pay for half. but come on why should i give them 450$ to repair faulty equipment which are a safety concern, my child safety locks do not work, i can not lock my car when i go in places for fear of not being able to get in, these doors were not mistreated to cause this and after researching this this is a known common problem, i was even told this by a gm customer service specialist, this should not be at the owners expense warranty or not, i do not have the money to fix this so i have to pray that nothing happens to my kids while i have to deal with this issue.

 2008 chevrolet impala gearshift could not be moved from park. towed to don brown chevrolet (after tow driver disconnected shift linkage). diagnosed as test and trace ground cirduit to broken wire in center console. talked to service manager who reported that technician stated wires moved when the shifter was moved which likely caused wire to break separate. potential for driver to be stuck in park in a risky / unsafe situation exists.

 My vehicle i purchases fro the dealer was supposedly in excellent shape. not until i moved to los angeles, ca. i realized that the engine was not performing correctly. the engine is to drop down from a 8cycl to a 6cycl when it is in overdrive (60+mph). (this is called 'active fuel management system.) my engine would not due that. i took it to several dealers but they refused to fix the problem. dealer said it wasn't their fault. we bought this car from an auction. i feel their was something wrong with the car. dealer inspection checklist was dated 3/26/2008. the car was a rental vehicle prior to me purchasing it as a used vehicle. the odometer reading was 12410 on 5/17/2008. i feel their was a problem with the engine safety. *tr

 Whenever the outside temperature drops below approx 20 degrees f and the vehicle is parked overnight, the factory remote starter and the keyless entry systems don't function unless i hold the transmitter directly above the hood of the vehicle. in warmer weather, the system works from distances greater than 50 feet. it has been to the dealer 3 times for the problem already and the problem still exists. thus far, the 2 transmitters and the receiver have been replaced. *tr
