Electrical system
49 reports2 fires
“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…”

“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…”
Air bags
24 reports7 crashes1 related recall
“"off" remains illuminated on my passenger airbag light whether or not someone is sitting in the passenger seat. It's actually somewhat rare to see "on" illuminated. There was a recall on this model for airbag issues but my vehicle specifically was not recalled. My vehicle was recalled for catalytic converter but I'm still getting codes. Most of the problems the Sonic has been recalled for, my vehicle has symptoms of but I get cannot afford to pay repair cost up front and I cannot find a mechanic who would be willing to take the steps to report my vehicle should've been apart of the recall.”
Power train
20 reports1 crash
“My auto started out with a Check Engine Light. I noticed the engine smelled of overheated radiator and coolant smell. Parts were replaced for fix (Hose)...but check engine light continued as well as the overheated coolant smell. The auto was placed for checking on machine for codes for check engine light, but none of codes made sense to Mechanic. Told to bring back for further testing/looks. Brought back several times. No idea what was wrong but last time I was told I needed to leave for extended testing and test driving as gears were not shifting in D struggled engine for me, no acceleration and RPMs raced at times. (Dangerous and unpredictable on highway and in town). Now I turned in for testing to Chev Mechanic, and now am facing a part that was replaced in control of electrical (over $500) and after they repaired that and tested I am told that I have a TOTAL TRANSMISSION REPAIR over $5200 - for a 2014 auto!!! It was in with dealership mechanics a total of 6-7 times. I was informed the electrical controls were confusing the engine reactions. Auto a dealers for $5200 + $500 repairs now 20230702 and problems seen & looked at since March for smell of…”
