cooling ISSUES - the WATER PUMPLE , cooling TANK . the WHOLE COOLING . my CARE HAS BEEN SHOP 5 TIMES AT JBA for cooling system
NHTSA complaint #11569927 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
We have had to deal with severe overheating issues and failing parts our entire ownership of this vehicle, both of which then cause other parts to fail, as the parts are so poorly made and heat sensitive. We have replaced the turbocharger (twice), intake manifold + valve cover (twice), catalytic converter, the radiator (THREE TIMES), the cooling fan (twice), the MAF sensor (twice), and much more. All of this has been done over the course of 18months. This has easily been the most expensive car we have ever owned due to the constant repairs, all of which has been because of Failing Parts and overheating.

2013 Chevrolet Sonic 1.8 L , fuel system lean ,mass airflow sensor, in limp mode preventing acceleration, gas tank when added gas....shuts down after start up-fuel system/gasoline; may cause possible fuel leak and could combust, alarm system and locks don't properly function - electric system equipment, insufficient welds...around fuel tank and front of vehicle on bottom by driver's side could also cause combustion, bcm codes that came up were communication, electrical, fuel, windows, and airbags! AutoZone codes were po171 and co561-77,I looked up recalls , several came up for my make and model but weren't specific to my vin# however my vehicle is doing everything pertaining to them! And I looked up if there was any special coverage on it and said there is...before 120k miles or ten years time. And I was never notified of it & never received anything in the mail ...

FUEL/PROPULSION SYSTEM
My cars coolant is leaking and the source is unknown. My car has overheated twice and my mechanic has been unable to find what needs to be repaired. The coolant has need to to be filled twice within a 6 month period. Now my car is having other issues with the catalyst system that lead me to believe the coolant leak might be affecting these other parts. My catalytic converter was already replaced and the same code has popped up 4 months later.

FUEL/PROPULSION SYSTEM
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 issues. It’s been roughly 4 weeks now and they have been extremely negligent and apathetic. With these issues, everyone’s safety is at risk. My suspension went out and could’ve caused a more catastrophic accident. A fire could’ve broken out with other vehicles surrounding me cause major injuries and death. I’ve seen and read many posts and testimonials and threads online from various independent resources that state very very closely the same issues. Almost verbatim. I’ve been trying to get these issues inspected by the dealership, but they all give me the runaround and don’t want to fix not find a solution. The check engine light has always been on since I’ve Owen the vehicle and the dealership where I purchased this vehicle said having the check engine light on is okay. I need help getting repairs done!

FUEL/PROPULSION SYSTEM
Dashboard speed indicator dimming and getting brighter for no reason. no warning lamps. Check engine lamp turned on then after fueling vehicle engine won't start, or won't shut off. Vehicle is an automatic transmission. A button must be engaged to put vehicle in park, drive, etc. The Button often sticks and keys cannot be removed because the transmission won't go in to park . On July 17 the button popped out while driving. This could have stranded myself or my family. The cause of the issue is unknown, but drivers may become distracted when the end of the automatic gear shift lever pops out or as in my case when putting the vehicle into park it pops out and breaks off entirely. I believe it to be a defective part that can easily break. My vehicle has less than 70,000 miles. It has not been assessed by an insurance agent or dealership yet
NHTSA complaint #11474377 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
Purchased this vehicle in February 2022 with 105,000 miles. Oil sticker indicated recent oil change and oil color was light and clear. The day after purchase the check engine light came on. Diagnostic scan indicated bad thermostat assembly and 2 oil sensors needed replacement. Radiator fluid was low. AC didn't cool. Repairs completed almost $900. The check engine light came on again the next day. The check engine and check oil lights/alarms need to be actual gauges. The vehicle overheated 3 times due to low coolant and faulty fan sensor fuse. Where is all the coolant going? A leaky hose was replaced but it didn't fix the coolant leak. Of course the car will easily overheat so I keep coolant with me to avoid being disabled during rush hour traffic on the Interstate in 105 degree temperatures. The engine continues to run hot and the check engine light stays on. The oil light/alarm is something new that started last Monday after driving 20 miles to Yukon, OK. No warning of any problem until I exited onto the service road to wait for a green light. The oil alarm/light turned off upon acceleration but returned again when the idle RPM went below 1000. Repairs were estimated at over $2200 for a new oil pump. I requested an engine flush and oil change instead since an oil pump could NOT be located. The oil filter was found to have collapsed but a new oil filter did not fix the low oil pressure at idle. So many defects with this vehicle!!! What the heck???? Odometer reading today is 107,364. It seems Chevy has manufactured a car that will barely make it past 100,000 miles and repair parts aren't available? Something isn't right with this picture. This car isn't safe to drive. Sincerely, NOT-Okay in OKC, OK.

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
