NHTSA ODI 11468715

Driving at night my car headlights/instrument panel shut off on their own. I couldn’t see had to slam my brakes and pull over. Nothing I tried would turn them on. After almost a minute each time they just came back on theirselves. After googling this seems to be a known problem with Chevy impalas but no solution. This is highly dangerous. There were no warning lights that came on or anything. I was able to still drive the car, turn it on and off, etc but they wouldn’t come on until they did on their own. Thank goodness no one was behind me or something in front of me cause I was on a none lighted 55 mph road

51,000 miles. System has failed three times. first two covered by Warranty. Not under warranty now. There are numerous complaints about this problem. It will now cost me up to two thousand to repair. car is at risk of fire,failure to start and other major electrical problems. Dealer wants $140 to diagnose, I am afraid to drive this car.

At about 86,000 miles I began getting a grinding noise from the left front side the wheel seems to lock up associated with a grabbing that I can feel when turning the steering wheel to the left. When this happens the Service Stability Trac and Service Trac Control indicators sometime appear but not always. I took my car to a GM Dealer locally a diagnostic performed said it was wheel hub assembly (bearings). Due to cost of dealer labor I took car to my local mechanic at his private garage. He performed a diagnostic and confirmed the assembly should be replaced. The assembly was replaced at my cost and has since been replaced twice more as warranty replacement because the mechanic thought the assemblies may have been defective, this after only a couple thousand miles or so on the replaced assembly. Typically, it happens at low speed, and mostly when turning left. It becomes a problem when I'm driving in busy traffic and turning at an intersection because it will just lock up and not let me go, stopping me in the middle of the intersection subjecting me to the possibility of being crashed into by other drivers. It is very frightening when this happens.

Started getting service side detection system warnings. Learned there has been a problem with this blind spot system. GM fixed it until Jan 2020 they say expired and my mileage was too high v problem just started last week of Feb 2022. 134k miles on it. Everything ran great but there are warnings from 2 years ago of dangerous repercussions from this defect. They won’t fix it and we can’t afford to have them fix it. I never got any notice of the problem from GM.

NHTSA ODI 11455900

My blind spot light on my side mirror was flickering, and now it just stays on. I read online that the sensor in the bumper can overheat, causing a fire, but Chevrolet doesn't have a recall on it. I ended up shutting off the blind spot sensor option on my car. I utilize the sensors, especially on the highway when I travel. There hasn't been a warning light go on as of yet.
