2014 Chevrolet Sonic engine problems

“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…”

“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…”

“Overall and to the best of my knowledge, the malfunctioning and failures on my vehicle were the suspension and engine. They are the culprits and it’s honestly very scary and traumatizing to have them completely fail, especially since no one is ever prepared for accidents and/or potential death to happen. Otherwise it wouldn’t be called an accident. With the suspension overall, it’s just awful. CV Axel, control arms, everything with the suspension just failed. With driving over the tiniest bump on the road you feel your is about to literally fall apart at any minute because of the clunking and metal in metal noises it produces. The engine is faulty as well and I am pretty sure the faulty engine happens due to the faulty suspension. When I look under my car there’s something leaking. I don’t know what it is, but it’s poses a safety risk not only for the driver and the passengers, but also to the rest of the world. I know that there was a recall early on about fuel tank breakage or something that could lead to fire ignition. But my vehicle according to my VIN wasn’t on this recall. I have contacted the dealership and a certified service center to inspect these…”

“The contact owned a 2014 Chevrolet Sonic. The contact stated that while his spouse was driving approximately 35 MPH she noticed smoke being emitted from under the hood. The contact stated his spouse saw no warning light being illuminated. The spouse pulled off to the side of the road and exited the vehicle safely when a fire began to burn from under the hood. The fire department was called and extinguished the flames with water. The police were also on the scene and wrote an incident report. The contact had the vehicle towed to his residence. The contact was advised by his insurance provider that the vehicle would be listed as a total loss. The manufacturer had not been informed of the failure. The failure mileage was approximately 60,000.”

“Car has no temperature gauge. Car had oil change. Then went to put gas. When I started in the highway. The temperature sensor turned on. This was terrifying as it was night time and I was on a highway on my way to visit family. The car could of caught on fire. Pulled over called a tow truck. Water pump was replaced and cylinder heads and gaskets. This was done through the warranty company. Car was returned to me on 14 December 2021 and was in a repair shop the following day because of the check engine light was on. Car now needs new motor as coolant was going inside the motor. Sensors had never gone off before that day. Currently car is in the chevy dealer for over a month trying to figure out who will pay for the repairs as I also had an extended warranty. Car had 57000 miles when it failed. Chevy repairs will be of about $7000.”
