The catalytic converter and exhaust manifold are suspected to be malfunctioning. These components are part of the vehicle's exhaust system, and their failure is believed to be contributing to hesitation and skipping during operation. Both components are available for inspection upon request. The hesitation and skipping reduce the vehicle's responsiveness, creating a safety risk in traffic. This issue could hinder safe merging, overtaking, or maintaining consistent speeds. Additionally, malfunctioning exhaust components may lead to increased emissions and pose a risk of toxic gases entering the cabin if leaks are present. Check engine light displays. The problem has been confirmed by a professional auto mechanic during their inspection and diagnosis. The components have been inspected and diagnosed by an independent service center (the auto mechanic). …
I been having the same problem for a year now.. constantly putting it in and out the shop and no one can find out what's wrong with it.. the engine will loss it control and stop working in the middle of traffic which almost caused me a wreck several times. The Chevrolet dealership hasn't done anything to help but charge me to look at it and they didn't fix the problem. I have three kids and it has been a safety issue which is our only way to work and school. The car will skip constantly in the middle of traffic and several times someone almost ran into the back of my car. It will say engine power reduced, service traction and service sec I have spent ton of money trying to fix the issue and I have read several people have had the same problem.
To Whom It May Concern: My 2012 Chevrolet Malibu LS HASN'T been involved in an accident but I feel it necessary to report it! Due to issues involving my electrical system and other components of the vehicle that aren't working properly, the vehicle is inoperable! Beginning in April 2022, I have experienced issues with the vehicle starting (one day it will start and drive normally, another day it might not). Then it started stalling unexpectedly. Granted, I've had the car 10 years but I've never had these problems! It's been serviced and the problems still exist! These problems could easily cause an accident; I'm grateful I've been spared from tragedy! These issues need to be addressed and I'd greatly appreciate hearing from NHTSA!
The electronic stability control activates under normal driving conditions. Power to engine is reduced, car does not brake or accelerate appropriately with this happens. It appears to be a problem that is reported frequently and one that has been a recall on some vehicles but this VIN does not show that recall. It puts me and others at risk because the car suddenly stops going at speed and lurches when trying to stop. Scans were done at a local auto shop which indicate issues with ESC. Warning lights include ESC activated, Engine power reduced
This car will not start!!!! It starts when it feels like it. I've been stranded after work so many times for unknown reasons. Multiple mechanics have inspected car and cannot find the issue. Go on YouTube and search for this year car and you'll find so many people in the same situation as me. The car has battery but the engine will not start. GM cars have this issue in common and it's ridiculous GM cannot stand behind their brand. Please HELP US!!!
For 4 years the car intermittently would turn on all warning lights, shake, become hard to steer and steer in unintended directions. We paid $1500 for the dealer to fix it and we still had the problem. Today, the car will drive less then a mile and die. When we start the car all warning lights come on, the vehicle vibrates and struggles to keep speed of 5 mph or so then will die.
ESC reduced power reads across my monitor's screen. It could be numerous of these that cause this. I've done what I can afford, but no luck. I've done research & it's very common for this to happen among these. Please help me out with at least pinpointing the problem, thanks!
