general problems of the 2007 Chevrolet Impala

Check engine light code p2138 change the throttle pedal position sensor the next day the car dropped down to 5 to 10 mph information center said engine safety been reduced to 5 to 10 mph plus my traction control light came on then information center said service traction control put my old throttle pedal position sensor back on and it turn traction control light out and the car went back to driving normal don't know how long its going to last before it goes back to 5 to 10 mph and the information center says engine decelerate to 5 to 10 mph. Was on highway in texas had to get over on shoulder quick car just slow down quick and pedal was to floor. Also keep failing state inspection due to failed obdii test ( see vir).

Had issues with my 2007 Impala 3. 9l stalling and reducing power on my wife, and at times almost leaving her in or on the road. I have replaced the throttle body, throttle peddle ( twice ) and had the car flashed at the local gm dealer. Now the car not only reads reduced engine power it read starting disabled service throttle and died while she was driving down a busy highway during rush hour. . Causing her to almost be involved in a bad wreck. This seriously needs to have attention of whoever at gm is over safety, cause this issue will end up in a really bad situation if or when someone ends up seriously hurt or killed. I mean you really need to program them to slowly reduce power, not just tell you then shut off completely and have the driver fight and panic to get off the road through traffic, while not getting run over in the process. But if there is a fix we need to know.

While driving my car to work on Tuesday 11-12-2019 at 6 am in the morning, my battery light came on then, message displayed battery saver active,ac hot shut off, traction on and reduce power, everything came on in dashboard and about 10 minutes later the whole system shut down, and car will not start back up. Had to get someone to jump start in order to start car back up it will run a period of time and it happen again even after replacing a new battery, starter and alternator I also taken it to dealer ship to run diagnosing test as well and they charge me for service although they said they didn't find anything wrong with charging system at all . But this occur during the busy time off the day and a lot of traffic.

Power steering box when checking fluid pop noise when taking off cap also changed serpentine belt still squealing stiff steering leak not detected at that time . #2 shifting from 1st to 2nd gear is very fast not normal.

Intermittent traction light and abs light poor acceleration.

My wheel started to cluck every time I drive, then my speed want go as it ahould.

Well my 2007 Chevrolet Impala want drive or move so I don't if it's the transmission bad or not I need answer please it's leaking fluid and oil as well.

Takata recall while driving I keep getting a �engine power reduced� message and my car immediately shuts off in the middle of traffic.

Car randomly displays reduced engine power. On interstate reduced down to 20mph could have gotten my family killed. Researched online alot of imapala having same issue. This is very dangerous.

Service traction control engine power reduced driving down the interstate and it dropped the speed from 75 to 40 in matter of minutes my family almost got ran over by a semi this is a serious safety issue and someone is going to get seriously hurt.

My issue started with my car turning over. It would not want to start first try but would turn over on the second. Some times it would start fine and others it hesitated. After dealing with this for a while my battery died after spending a little while idling. Took it to check the accelerator and the battery but both were fine. Continuing to intermittently act up when starting, it also started to show other problems. I was getting in my car to leave and it started up fine but before I could pull out of my drive way my car started shaking and showing an "engine power is reduced" message. I turned it off ran inside and when I came back out to show others the issue it started without a problem and did not have the message any more. Still have the turnover hesitation, I continue to drive it however it started to shake and show the same engine power reduced message as I pulled into my apartment complex. Also has done this when leaving and turning into a main road, causing us to pull over and wait to start it again. Took it to get codes tested again and it pulled up a didn't match code. After doing research tons of others had the same problem and worse. Many showed the solution to be replacing the throttle body and throttle position sensor which we did. Slight hesitation on the start up but took it around the block no issues. Went to test it on the highway and before we even made it the engine power reduced came on and car shook again. There and so many others that have had this problem and many have not found the fix. Extremely disappointing since we cannot return the part after it's been installed. I am worried to take my car out and drive it on the highway because I do not want this to happen while I'm at increased speeds.

Last may I was driving my car from work going approximately 40 mph a message came on the information screen. Something about going over 160mph. The car suddenly slowed, couldn't seem to find the proper gear. At the same time the speedometer was going up and down showing 60, 30, 80, 0. Then it cut off. I put the rolling car into neutral and started it. It fired up immediately. I put in gear and continued until it was safe to stop. Let engine cool off and drove home. The speedometer continued to fluctuate, it also cut off and flashed the message again. Called dealership next morning and took in. They came back with diagnosis of transmission failure, need to replace. I shelled out $4000 for the transmission, now it is slipping. I drove home today and that message flashed across my screen along with the transmission struggling to find the proper gear. The speedometer was moving up and down. The speedometer was replaced when the transmission was replaced. I have contacted the dealership to schedule an appointment. I also made a formal complaint to gm.

While driving, my car gives a message of "reduced engine power" and completely shuts off. . . Regardless of what speed I am driving. This has happened 3 times in the past 2 days. Very unsafe! I have read online of hundreds of this same type vehicle having this problem. Why isn't this a recall issue? I believe another car manufacturer had a similar issue with one of their accelerator parts and that company recalled and replaced these parts for no charge to the owner. I believe Chevrolet needs to do the same thing.

While driving the traction control light comes on as well at reduced engine power. It drops the speed of the car down to 40 mph or lower. It does not accelerate easily when coming to a complete stop. This can cause an accident as I have had several near misses. The light will go off if you turn the vehicle off for a few hours but does end up coming back on.

Driving down road at 65mph when all of a sudden reduce engine power comes on and my car shuts off the cruise and I cant get the power up over 15mph on a major highway. . . . . . . . . . . .

I was driving down the interstate about to get off on a exit and the service brakes and service traction control light came on. The car was unable to slow down, the car jerked and the brakes went out.

While driving my vehicle, the traction control light and check engine light came on. . . Then a message stating "engine power reduced" came on. My car dropped the speed from 60 to 20, on the highway. It happened again a month later and I was told that my accelerator pedal needed to be replaced. This happened again in March of this year, and I was told my fuel pump had gone out. Now it has happened again this morning, and the mechanic doesn't know what's wrong with it because it happens intermittently so he can't diagnose it unless it does it while the car is in his possession.

The vehicle has a reduce engine display and the acceleration starts to slow down the car to around 40mph. Sometimes the car will shut off.

My wife's daily driver is a 2007 Impala . She was driving home with our three kids when the car started shaking and the reduced engine power display came on. After that she could only go about 25mph. This scared her and could have caused an accident. I looked online and found forums about a lot of people having the same problem and it pisses me off that gm hasn't recalled these vehicles . Does someone have to die before this situation is taken care of?.

While I was driving an error message appeared on the panel "engine power reduced". The car immediately slowed down as if the engine had cut-off completely. It did not and I was able to drive to the side of the road at about 10 mph. Luckily it was late at night, the few cars that were driving near me were able to change lanes before a collision occurred.

Vehicle's transmission slips when accelerating, and also jerks when idling. This is a common issue that has been reported in multiple places by a large number of people. Issue has been increasing in frequency - making this car unsafe to drive, yet Chevrolet has not bothered to address the now obvious problem.

(1) my wife pulled into a parking space at our church and applied the brakes to stop. (2) the car continued on rolling over a concrete barrier and knocking down an ornamental iron fence surrounding the parking lot and continuing out into the street where it finally stopped. In addition to the damage to the fence, there was considerable damage to the front of the car. (3) cause of failure has not been identified. On one or two previous occasions, when pulling the car into our garage I have had the car stall and then surge forward. Car is being taken to a body shop to repair the damage.
