Engine light came on while driving and car started to slow down. It can't be throttled beyond 10-15 mph, so pulled over. Took it to closest auto parts shop and the code reader came up with P2101/P2135 indicating there is a potential problem with 'throttle' functionality. This problem was reported by GM eng. Team and there is a technical service bulletin with the same model but GM is not considering to fix the issue with my car as it is out of warranty. This is a serious safety concern and expect GM to help fixing it. It is same as NHTSA 10034366.

Car idles rough and shudders in park and while stopped at traffic signals. Car has died at stops numerous times but usually starts again with no problem. When driving at all speeds and depressing the gas the car has no response or loses power and will not accelerate, then the rpms shoot up and the car lunges forward. This is dangerous! replaced the maf sensor thinking this could be the issue. This did not correct the problem and car is still acting up. Intermittent failure. No trouble codes and no check engine light.

In August 2014, I purchased a used 2009 Chevrolet Aveo for my daughter. The vehicle had low mileage (16K) and, according to carfax, two previous owners with no reported maintenance problems. I had the car inspected by my local Chevrolet dealership before finalizing the purchase from a Nissan dealership and there were no problems detected. On the date in of the incident, my daughter was traveling on the highway coming home for spring break. She was driving approximately 68 mph when the car began to decelerate - the speed dropped from 68 to 58, then from 58 to 48, then, when the speed dropped to 38 mph and the car repeatedly failed to respond when she pressed the accelerator to regain speed, she was forced to pull over to the side of the road. She called me and described the problem. She waited about 5 minutes and then cranked the car again. The car did respond when she pressed the accelerator so she thought everything was okay and merged off the side of the road back into the flow of traffic on the highway. The car speed topped out at 45mph and then began decelerating. She pulled over to the side of the road again. She waited another 5 minutes. She again cranked the car and pressed the accelerator. The car would not move although the RPM needle moved appropriately. At that point, she called onstar and arranged for a tow truck to pick up the car. The vehicle was taken to a nearby Chevy dealership. The service manager verified the problem. Their recommendation was to replace the transmission in a car with only 1900 miles on it.

I was driving the vehicle home from work and while slowing down at a stop light, the vehicle started to shake and the check engine light came on. After that I went to accelerate when the light changed and the car would not go above 2 mph, even with the accelerator all the way to the floor. I brought it back to the dealer for the third time since I bought it 7 months ago and they are working on it now. They said it was the part that allows fuel into the engine.

As a father I am writing this on behalf of my 18yr old daughter. This vehicle has lost steering, brakes and acceleration 3 times over 2 years of ownership. Each time has been at low speeds (2mph - 10mph) while driving at low speeds in traffic, the Aveo will loose the ability to accelerate, no matter how far the gas pedal is pushed down. The brakes only work slightly, and the pedal is hard push down. The steering is very unresponsive, similar to the brake issue it's hard to steer. While the above 3 issues happen at once, the engine is at idle. To fix, she has to turn the car off and restart.

I was driving up hwy 31 in columbus and my car was like it wasn't getting gas. The engine continued to run. I pushed the accelerator to the floor and it made a connection again in approximately 1 minute. This happened twice and I took it to poynter Chevrolet in seymour. Nothing showed up on the computer and they kept my car 3 days and could not get it to duplicate the problem. My car was only doing this once a week, now it is doing it most of the time. You have no warning that it is going to slow up, only moving from the momentum of the previous speed. I looked on the computer at "problems with Chevy Aveos" and there are several people on the internet with the same problem. I called Chevrolet and they said they only do recalls from calls from mechanics who have fixed the same problem several times. How can I get this fixed if they don't know what is causing the problem? this could cause a fatal accident several ways so I'm afraid to drive the car. If I am on the highway going 70 mph and the car decides to just quit, I could get hit. If I'm making a left hand turn and there is on coming traffic I could get hit. I have a 2009 Chevy Aveo and I am afraid to drive it. Please look at the internet at all the other owners having the same problem.

While waiting in drive-thru for my order, my car began to shudder violently. I was idling at 1 RPM on the meter. Suddenly, my car accelerated itself up to 4 RPM. Had I not had my foot on the brake, I would have rear ended the vehicle in front of me. This persisted throughout the drive-thru and onto the roadway. I tried to accelerate and shift into second gear, but the car lost all power and then would rev up to 35mph without warning. Not once did my check engine light come on. Brought it to the dealer and was informed that my information cluster needed to be replaced and that Chevy doesn't cover that part outside of the warranty period. I just paid my car off and the extended warranty just expired. I'm looking at paying $700 and they're not done looking at my car. This is unacceptable. Something needs to be recalled because from what I've read, my car isn't the only one that has experienced this.

Bought 2009 Aveo ls sedan brand new for daughter so she would have a safe car for college. When the car warms up it will not respond to gas pedal inputs. This happens on and off at random times, sometimes in the middle of an intersection, other times on the highway. We have parked the car as it is unsafe for our child to drive in the current condition. Trips to the dealership result in "we can't find anything wrong". frustrating.... this was an expensive lesson to never buy a GM product again!

The failure recurred intermittently. The contact stated that prior to the acceleration failure, the cruise control was activated. The vehicle was taken to the dealer for diagnostic testing where the technicians were unable to diagnose the failure and advised that the failure may have been caused by the floor mats. In addition, the electronic door locks were inoperable and was erratic. The vehicle was not repaired. The approximate failure mileage was 28,000. The VIN was not available.

On the first incident, when driving at 40 mph started shaking like it wanted to stall and stopped accelerating. The next day when stopped at a light it started shaking and the RPM gauge was going up and down. It didn't happen again until about a month later, which is when I took it in, but the dealership couldn't replicate the problem. It kept happening -- the car would start shaking while driving like it wanted to stall and would slow down. Once while driving it dropped the acceleration to about 20 mph and would not go any faster, then just lost power to the engine. I took it again for one week but they couldn't replicate the problem. I got the car back and it was fine for about two weeks but now is happening regularly. Sometimes it just shakes quickly but something the acceleration completely drops and the car will just stop while I am driving, which is scary. I'll try to accelerate and nothing will happen, then finally it will go again. Sometimes I will stop and then the car will lurch forward. The RPM gauge is always moving up and down. There is no pattern as to when it happens. I've taken the car in two more times and still nothing. They just installed a data recorder and I recorded four instances and gave it back; I'm waiting to hear the results. It's very dangerous, because I will be driving in traffic and my car will just stop, and since I am not braking there is no indication to the car behind me. Also, no lights are coming on (no check engine light, etc.). I had my oil changed the first time since I was about due but that made no difference.

The contact owns a 2009 Chevrolet Aveo. The contact stated while driving various speeds and merging onto a highway when the accelerator pedal was engaged he was unable to increase speed. After coasting to the side of the road in order for the vehicle to reset the vehicle was taken to a dealer who advised him that there was a wire loose on the sensor for the acceleration. The loose wire was repaired. Approximately 4 months later the failure recurred. The manufacturer was not notified of the failure. The failure mileage was approximately 9,000. The VIN was unavailable.

I bought my 2009 Chevy Aveo a year and a half ago. When my car was at 6,000 miles, I drove my car to school and parked it in a parking garage. When I returned to my car at the end of the day it would not start. My car was towed to a dealership and a faulty fuel pump was replaced. When my car reached 16,000 miles I began experiencing shaking at stop lights and stop signs, and very slow delayed acceleration when starting to drive after stopping. The shaking and delayed acceleration would occur randomly yet was very likely when my air conditioning was on. I brought my car to the dealership yet they said the problem could not be replicated. My car is currently around 22,000 miles. Over the last week my car has begun decelerating and then suddenly lunging forward while I am driving. The deceleration and lunging forward is happening when I am driving on local roads at about 30mph and when I am on a highway driving around 70mph (and everything in between). Today, pulling out of a parking lot, my car was very delayed in acceleration. When I stopped at a stop light, my car began shaking and then shut off. This problem is sporadic, yet increasingly worrisome and dangerous. Dealerships have not identified a problem and insist there is nothing they can do.

- Berkeley Heights, NJ, USA

The contact owns a 2009 Chevrolet Aveo. The contact stated that while driving at any speed the vehicle would unexpectedly decelerate, surge forward and then shake while slowing down. The contact would have to apply repeated pressure to the accelerator pedal in order to continue driving at a normal rate of speed. The vehicle was taken to an authorized dealer where the contact was informed an engine coil and cylinder head failed. The vehicle was repaired but the failure recurred. The failure mileage was 16,000 and the current mileage was 17,000.

My 2009 Chevrolet has had serious stalling or non responsive acceleration for 6 months now. On a regular basis the car will lose power to the engine; when stepping on the accelerator pedal. The car acts like there is no signals from the accelerator pedal to the throttle assembly. There are days when it does nothing at all. There are times when it happens then the engine will just seem to return to normal, then out of the blue the engine will lose power again. There are never any warnings or check engine lights. None have ever come on. We have taken the car to 3 different Chevrolet dealerships; and to one independent garage; who did have the problem happen once while I was driving with the owner, but the otc genisis device could not identify what was happening, it just recorded the history of the event. None of the Chevrolet dealers could get it to duplicate or find any codes in the 10 days they had the car. The problem seems to be getting worse. I have been taking videos with my htc droid when the car is having its problem (for all the good that will do). It is like keeping a journal. I show the RPM spikes and drops; the sudden deceleration and the ?no response when the gas peddle is pushed. The problem has occurred at all speeds, including when on the freeway. We have already spent over $600 on various (so called fixes); including a complete fuel system cleaning (including the throttle body cleaning) none have ever helped. I was told by a Chevrolet dealer it was a bad O2 sensor (but no check engine light had ever came on). O2 sensors always cause a check engine light to come on. I think it may be the entire ECU computer; but no dealer wants to admit that. I was told by the dealer today 01/04/2011; there is nothing more they will do; because we have too much negitive equity. They will not do a buy back. They have washed their hands of the issue. To bad there is no used car lemon law. 4 repair attempts and the problem is even worse.
