ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY
A new EverStart Maxx lead-acid battery (Group Size H5/47, 12V, 650 CCA) was bought at Walmart on 07/14/2026 and installed the same day in a 2014 Chevrolet Sonic. It was installed correctly: correct polarity, both terminals tight and free of corrosion, hold-down secured. The car ran normally for about eight weeks, with no warning lights or electrical symptoms. On 09/10/2026 at about 12:00 p.m., the car caught fire while parked. It had not been driven or started since about 5:00 p.m. the day before (about 19 hours), so the engine and charging system were off. The fire appears to have started at the battery. It stayed in the engine compartment but melted the underhood fuse box and the engine wiring harness. The local volunteer fire department responded, and a police report was filed. No one was hurt, but a battery fire in a parked, unattended car could easily spread to a home, garage, or other vehicles. The car had an earlier front-end repair after hitting a deer. It had been driven for more than a year since that repair with no electrical problems. The vehicle and the battery remains have been left in place and are available for inspection. The retailer and manufacturer have not inspected them yet.

SERVICE BRAKES, STRUCTURE:BODY, ENGINE
I purchased a 2012 Chevy Sonic with 65k miles on it from Carvibe LLC earlier this month. When I took it into Firestone for a full inspection, they found that the car has severe rusting to the mechanical parts along with the body of the vehicle - the entire structure of the vehicle is compromised. Someone spray painted the rust black but Firestone was still able to see the covered up rust. Firestone has deemed the vehicle unsafe to drive.

ENGINE
Engine Cooling System (Thermostat Housing / Water Outlet) The vehicle suffered a premature structural failure of the factory engine coolant thermostat housing. The component, which is manufactured from a fragile plastic composite, cracked completely open without warning, causing an immediate, rapid loss of engine coolant. This constitutes a severe safety hazard. A sudden, catastrophic loss of engine coolant under normal driving conditions puts the vehicle at immediate risk of severe engine overheating and sudden engine stalling or seizure while in motion. If the engine stalls unexpectedly in high-speed traffic, it strips the driver of power steering and braking assistance, drastically increasing the risk of a serious collision. General Motors is fully aware of this pervasive material defect across the Chevy Sonic model years, yet they refuse to issue a safety recall, forcing owners to operate vehicles with inherently flawed, dangerous plastic cooling components. They also refuse to help in getting the vehicle repaired or share the cost.

ENGINE
This car overheated and a head gasket blew. I am on a Facebook forum, and it seems like all of these cars have these problems. The Chevy Sonic ltz turbo 1.4 2016 is known for coolant issues and head gasket failures. My car only had 104,000 miles on it. It should last a lot longer than that, but this is a common issue. For some reason there was a recall but they stopped fixing cars with 1.4 engines that came out after 2014. There cars don't have temperature gauges and when they overheat they don't tell you until a light comes on the dash and by then it's too late and your engine is blown. This should be illegal. Chevrolet needs to fix this.

ENGINE
Around April of 2025, I noticed loud engine noises and cold start loud noises coming from the engine. My car has been in the shop multiple times since then and I opened a case with GM about multiple repair issues with my 2014 Chevy Sonic LT even though I take excellent care of the vehicle and perform all maintenance on the vehicle, and now this loud engine noise issue and leaking oil. I was driving home from a relative's home Saturday night Dec 27th late evening on the expressway when I noticed my car driving very sluggish and jerking and make extremely loud engine noises and continued burning oil smell in the cabin of the vehicle. No check engine light or oil light, now I had stopped by the service department earlier in the week when and oil pressure light came on, and they stated no issues. I made it home without incident, but the car was not running right. The car was brought to the dealership service department Monday Dec 29th, and they informed me they found broken plastic pieces of guard rails that secure the timing chains in the engine which may have caused serious damage to the engine. The dealership wanted 4k dollars to repair it after they could not properly diagnose a known online issue that I found out a lot of these Chevy drivers have found out about and having me repair other items on the car instead of fixing the leaking oil problem and whatever was going on in the engine. The manufacturer has not inspected this issue now only the service department at the local Chevy dealership has, however I had a case open with GM before this final incident occurred on Nov 1st after my last repair and complaint to the dealership about loud engine noises. GM would not take my concerns seriously and stated we are sorry, but your car is out of warranty even though this is a known issue of this plastic guard rail failing and other serious engine issues with Chevy. I would like the NHTSA to be involved in this matter and investigate this matter if possible.

ELECTRICAL SYSTEM
Purchased from Carvana. Nine days after purchase came out to a dead battery took it to the authorized dealer and they said the battery was a bad cell battery. Replace the battery. Six days after they replaced the battery it was dead again. This time they had it in the shop for two weeks before they found the issue. It had been aftermarket wired with a GPS tracking system that was draining the battery. They said if I have any further issues with it, I need to take it to a dealer. They gave me a bag full of multiple components that had been added to the vehicle. I do not know how Carvana missed them all.
