My 2018 Chevrolet Sonic 1. 8l has experienced repeated complete battery discharge and electrical failures over approximately two years. The factory infotainment system does not consistently shut down after the ignition is turned off. I must follow a specific shutdown procedure or occasionally remove the infotainment fuse to prevent battery drain. On October 10, 2026, after a three-day trip, the vehicle was completely dead. My 2,000-amp portable jump starter could not start it. Another running vehicle had to supply power before it would start. The vehicle then operated and restarted normally for approximately three days. On October 13, 2026, after several successful starts, I parked at 10 am. By 4 pm, the vehicle produced rapid clicking sounds, then lost all electrical power. My jump starter again failed. Another person had to help push the car into the street and connect jumper cables to a running vehicle before it could start. Autozone testing initially showed battery failure, but subsequent tests passed. The alternator and starter reportedly passed. I purchased a replacement battery on October 13 for approximately $135. The vehicle started normally afterward, but the underlying infotainment malfunction remains unresolved. Gm technical service bulletin 18-na-048 documents unwanted radio activation and possible continuous parasitic battery drain in certain 2018 Chevrolet Sonic vehicles. The bulletin identifies a possible manufacturing-related cause. Whether this specific defect affects my vehicle has not been confirmed. I am a disabled woman with chronic illness and limited mobility. Being unexpectedly stranded creates serious safety risks because I cannot necessarily walk for assistance or tolerate prolonged exposure to extreme temperatures. I request that NHTSA investigate whether this is a broader safety-related electrical defect and determine whether a manufacturer safety recall is warranted.
The has as well as mileage is not accurate and it constantly changes even while not driving which is adding more miles to car than actually is and you will never know how much gas you have in car truly which is safety concern especially if you are driving on interstate and can’t tell how much gas you have in car and suddenly run out of gas while other are behind you going 70 mph which can cause a wreck.
My radio turns off and on, on its own. Also when I have my bluetooth turned on for my phone, it gets stuck after I hang up the phone after a call. I was driving home from work on a state road. My right wheel bearing went out and I had to replace it last year.
Today I'm writing in behalf of carite of oakland park I had a email chat with brian mccoy the branch owner of the company, I was told by him that the car was put in as repo status, due to me giving the car back. I feel my life was put in danger numerous of times and due to the negligence of the company I was not given a reliable vehicle nor was I treated as a valued customer. . . Good day, I've made all attempts regarding this situation with carite I'm the time allowed. . I'm requesting a full refund of my money I've made it clear and I don't want nothing else from these people at this company. I've told the owner not to have the car delivered on today 2/8/20 he still insist the driver greg to do so, I've rejected to receive the vehicle instead of honoring my request I'm getting phone calls from other parties at carite I guess to reconsider! no, I want my money my life will not be in danger due to they're negligence. . Thank you,the items submitted are receipts of payments also, the day of 1/20/20 I drove to fort lauderdale on the accept ion of getting the ac repaired and the windshield. Nothing took place for being there for 6 hours only to head back home exhausted��� and to finally get 50 miles home the car started to blow white exhaust from the vents, I immediately called carite and spoke with kim, who's in responsible for repair and maintenance. I told her what was going on and that I've had enough. I get home, wake up the next day to go to a dr appointment only for the car to not star! I lift the hood so my neighbor could give me a jump and this is what I find under the hood. . ( the pliers next to the battery that was left there and I drove home with it on the car that's alone it's enough puts my life in danger. . .
My 2018 Chevrolet Sonic radio screen went black without warning while I was driving. I lost all functions through the radio screen. This happened a second time in route to work within a few days. I'm concerned that the radio may go black during an emergency when I need to use on star.
Having an issue with the radio itself, its went black a few times on me as I was driving. And also when I was parked. No response on it at all. Im afraid if something happens like when im in a wreck and when I try to call onstar while its not working im afraid of it not connecting, and also ive had issues with the window switches not rolling up or down the windows no clicking noises when I push on the switch all four have done it, acting like its not getting a electric signal to the switches, what I usually do when that happens is pull the car over turn off the iginition and let the car sit for 30 seconds then start the car and it usually works. Ive also checked to make sure the safety switch aint on and it isnt.
