I have 2011 Malibu. The Service ESC, engine power reduced, and service traction lights are all on. Car starts jerking and bogging out. I have it in the shop 4 times in past 3 weeks. Any thoughts?
Was that the GM garage ? Your service codes can be read by a code reader anywhere to get the codes, google them, and find out what tests to run, or the condition the computer is implementing as a result. Ask your parts store if they have a code reader. write down what the codes are. read about each one, but you want to know why it is jerking or bucking. Fuel pressure ? Sensor malfunction? EGR valve ? Who knows? And what were the tests and results of your last 4 times you mentioned ? A car's computer may default to a runable strategy but act up and use a predetermined plan. The sensors may be out of range or giving data outside parameters. The predetermined plan lets you get it to the GM garage and get help to make it run right, then the computer can return to responding to your actual data.
When the mechanic read the codes they said it was the throttle position Sensor. So they cleaned it a yr ago. Car worked fine until 3 weeks ago. I took it in once again the code read the same thing. They cleaned it again. A week later it started again. So they thought it was the battery. They changed it. I didn't even leave their parking lot before it messed up again. So then they changed the throttle body thing. And i get in the car drive home and it did it again. I have put a few hundred dollars into fixing the problem, and now it has to go back into the shop.
You must seek help from the GM garage. Your shop is cleaning your throttle body, replacing it, and replacing your sensor that measures throttle opening, but they are not addressing your symptoms as well as your code, they are not completing the work. They have repeats of the condition and a recurring light. once the light has been on, the computer can put itself in a self management plan, or predictive mode. It stays in that mode. it returns to that mode. Their work should include the pinpoint tests, inspections, repair, clearing, and complete drive cycle, if the code recurs, they cannot resolve it ? they are to contact GM or the emissions authority to see if they are missing info about your calibration. I do not know, and am truly going from experience but only Mr. Goodwrench can help. Give him a chance to remove aftermarket parts or complete the work and implement GM updates or processor correction. Also, address the other symptoms. Some computers can also miss symptoms that indicate an issue and there may not be a code for what your tech at the dealership would know must be the case. Arrange a rental car, bring your receipts, give them research time or hotline time or whatever they need. That can simplify when the pressure is off but they understand the importance to the customer. Providing them a narrative letter helps the info get communicated, and they can refer to all the symptoms.
Continuing to drive a car with multiple symptoms could end up damaging the catalyst or rendering it ineffective, because of its cost, it is best if you seek their help soon and not wait. You do not want someone to keep slapping bandaids on this one in my humble opinion.
Mine is doing the same thing ... did you ever find problem?
does your vehicle have multiple problems? have you had an inspection for obvious causes, codes read ? What were they? read the first answer on this page please mr. goodwrench or the emissions certified shop they can recommend can get you all the help. doing your basic needs only can be checked by any shop.
Then read the third post. doing part of the work, but not the complete needs being met, can put you back at the first step. Too many people's ideas, without a complete solution, is obvious here. a real driveability tech may find a concern with the work that was done, or the completion of each step.
My 2011 Chevy Malibu has these three exact messages. I have an appointment with the dealership Friday. When I brought the cast on originally, after looking for about hour, they said I had a water leak which read doing onto the electronic accelerator causing it too temporarily short. Estimate $300 - $1500 to tear apart the dash and find and fix the leak.
I have a 2010 Malibu... it has been doing this for over 2 years now. Funny thing is; it only does it during the winter months. December through Feb. it does the same thing, same codes, same check engine light. I deal with it until it causes a permanent problem, GM service department is lost and they are only part changers, not full mechanics that really troubleshoot. If they cant read it on a screen or code, they have no clue.
So. . . I got an answer which isn't probably the root cause. The inner seal on my driver's door has been crimped which is allowing water to drip onto the electronic accelerator (how I miss the day of mechanical linkage). The dealership ordered the part a week and a half ago and was supposed to call me when it comes in ($175). In addition, I've tried to get recall parts installed on my car twice; the first time they said they didn't get the parts even though someone called me and told me they did. They second time, they said one 1 of the 2 parts were shipped to them; and it was broken! I seriously doubt I'll ever buy a Chevy again! (I miss my 1976 Chevy Impala)
Hi I have a 2011 Chevy Malibu I was driving home and the engine light came on and this came across the dashboard Eng Pwr Reduced can you tell me what that means
For me, the electronic accelerator had a connection ( I believe in or near the firewall) which had been soaked with water by the leak I described above. The dealership took it apart, cleaned it, put it back together and put a silicone sealant/gel around it to protect it from moisture until my new door seal comes in (which I'm still waiting on). I haven't had that engine light message, or a loss of power since (so far).
i have a 2011 chevy Malibu and i havnt had any promblems until now the ESC service light came on i called the dealer and they told me its going to be 99.00 dollars to look at it im praying that its not going to be a high price when they tell me whats wrong with the vehicle .......Answers please?????
Update on my post: It cost around $200 total to replace the crimped door seal and have the dealership take the electronic accelerator apart, clean it, put it back together and put a silicone sealant/gel around it to protect it from moisture. I've had the light come on once since then, but I turned the car off and restarted it and it did not come back on. So I'm three months without a problem. :)
What dos service ESC means
My car just got the same issue today.
What can I do to fix it?
Since my post of 5 months ago, I've experienced the sluggishness of acceleration, but have not had the ESC warning come back. This leads me to believe if your dealership should be able to take the electronic accelerator connection apart, clean it and reseal it - if your root cause is moisture like mine.
