2009 Chevrolet Aveo: sudden loss of power

Filed Jan 27, 2020 · Engine · 8,900 miles · NY

My 2009 chevy aveo has been nothing but trouble! The problem started with 89,000 miles. In idle, after about 2 minutes, the car would shake violently. I began to drive normally with no problem then the car surges, looses power, then stalled in traffic. After about 3 minutes of sitting, the car suddenly started then after about 4 blocks, lost power again. The car kept dying & restarting. Finally got home. Turned the car back on , the idle was going up & down, shaking violently while idling in park. The throttle body was changed, o2 sensor changed, mass air sensor changed. Air filter clean. This car is terrible. I will never trust & buy a chevy again!!!!! Shame on you chevy.! Get your quality control in check. I want people to know to stay clear of chevy cars!!!!!

You can't drive it anywhere it runs right then for no reason it loose power and won't accalrate while driving it will drop below 10 MPH in traffic or lose all power while crossing road or turning I'm afeead I'll b hit in side or ran over in traffic.

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.

The car lost power for no reason . It did not fully stall but lost power and would not respond. It would lurch forward, barely go, then recover slightly. This happened sporadically and was frightening and dangerous. The battery light began to go off and on. Mechanics could find nothing wrong and battery ok. In november, car lost power in traffic, almost had wreck, barely made it to shop. "strangely swollen" battery found and replaced. Computer and all systems checked. Incident happened again. Back in shop. Clutch replaced, tube replaced in engine, etc. Cost $ 1500. Car seemed to run fine but only for days. Began doing same thing again. But when I take it to mechanics, can't find anything wrong because problem comes and goes. It seemed to possibly be triggered and happened more often if I used onstar built in phone. Had it turned off and thought that somehow fixed problem but it happened again yesterday in traffic with my 93 yr old mom in car. Terrifying.. Can't get out of way if car coming in intersection. No one helps me find a solution. I contacted gm online they said they know of no such problem. Hundreds of posts online from aveo owners with same problem. Someone is going to die if this isn't made public.. We need a recall . Help please!

So we bought this car and noticed that it would lose power, buck, jerk, and sometime die. Usually after dying it will start right back up and drive fine for a while. We took it to a repair shop that told us to replace the throttle body. After we replaced the throttle body and had the dealer program it the problem persisted. We bought a new ecu from the chevy dealer and had them install and program it and the problem persisted. We replaced the coil pack for the second time in this vehicles history with no luck, same problem. Drained the fuel tank and installed a new fuel pump...... Same problem.... Amidst all these part replacements the car has been to the local chevy dealer at least three times and now a fourth time they finally called me after a week and suggested that they clean the throttle body.... I explained that it is brand new and should not need cleaning. They still apparently have no clue what's wrong with this piece of junk that is only 4 years old! Between the chevy dealer and our own time we have spent over $2000 dollars and the car still won't operate correctly.

Bought used the end of august 2010. Started having an issue with the car in october 2010. While driving the car would suddenly lose power. Example going 45 the car would quit accelerating and wouldn't go faster than 5-10 MPH. No matter how hard you push the accelerator the car won't go. The tachometer revs up and down but the car won't go. I have had the car in on several occasions and always get the same answer. They can't find anything wrong. In october 2010 the dealership cleaned the injectors and throttle body at a cost of $193.80. Didn't fix problem. In november 2010 they replaced the o2 sensors. Fixed the problem until I took the car in for a recall on the ignition coil and boots on june 21,2012. The car started having the same problems. Took it back on june 25,2012. They couldn't find anything wrong. The car has continued to have this problem on and off. Took it back to dealership on may 22,2013 and again after keeping the car for a week they still can't find anything wrong. Today, june 24 2013, the car is doing it again. This is very dangerous. When it quits accelerating there are no brake lights. In heavy traffic this is a problem. Someone is going to get hurt or worse.

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.

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.

Vehicle lost power to the engine. Stepping on the gas pedal did nothing. The car lurched and decelerated quickly. Power was suddenly restored to engine causing the car to speed up quickly, then engine lost power again. Car came to a stop, engine sputtered and then died. No warning lights came on. Restarted engine, car drove as normal. Took to dealership, they could find nothing wrong. Problem has continued intermittently for almost a year. Have taken the car to the dealership multiple times, they can find nothing wrong. The sudden deceleration has occurred at all speeds, including on the freeway almost causing a collision. The car went from 70mph to 40mph in one minute, sputtered for a while, and then came back to drive normally after several minutes. The problem happens within the first ten minutes of driving. It has happened twice in the same day after the car sat for 8 hours. The problem has not occurred for periods as long as two weeks but then comes back. The most extreme occurrences have been on side streets where traffic was not a problem, but if another car had been following closely a rear-end collision would have been certain. My spouse has driven the car and experienced the same problem.

Tl* the contact owns a 2009 chevrolet aveo. When driving at speeds of at least 35 MPH, the vehicle would lose power and decrease in speed without warrant. The contact would apply constant, steady pressure to the accelerator pedal until the vehicle would regain speed and resume normal operation. The dealer was unable to duplicate the failure. The manufacturer was contacted but did not provide any further assistance. The failure and current mileages were 10,682.
