CHEVROLET Complaints

Statement of Incident and Repair Costs While driving on the expressway at approximately 70 mph in the express lane with my family in the vehicle, the engine suddenly began to stutter and run rough. Within seconds, the vehicle lost engine power, the oil light came on, and the check-engine light started flashing. The sudden loss of power caused another vehicle to almost collide with us from behind, narrowly missing my family when our truck slowed abruptly. Because of the immediate danger, we were forced to cross two lanes of interstate traffic to reach the shoulder as quickly as possible, putting my entire family at further risk. We were then stranded on the side of the expressway. The vehicle was taken to the Chevy dealership in DeMotte, Indiana. Their diagnosis determined a catastrophic engine failure caused by lifter failure, resulting in bent rods and damage to the camshaft. Despite widespread reports and known issues involving lifter failures in this model, there is no recall for this year and model. As a result, we were left to cover the full cost of the repair. The dealership did not provide a rental vehicle, even though this truck is our family’s only means of transportation large enough to safely haul all of us. Insurance would not cover the failure due to the numerous notices and documentation showing that GM/Chevy is aware of this problem but has not initiated a recall. Total cost of repair: $8,801.53, paid out of pocket. Of which we had to borrow and scrape to figure out how to pay for it, due to it being our only vehicle for our family. Now we are left with the uncertainty as to whether the same thing will happen again, endangering the lives of our family yet again, due to living out more in the country and having to drive 30+ miles one way to get to grocery stores etc… on roads that have a speed limit of 55mph rt 49 going north from south of the Kankakee river or the expressway again where the other incident occurred I65 by Lowell Indiana exit.

The contact owns a 2015 Chevrolet Camaro. The contact stated that while starting the vehicle, the contact noticed that the ignition switch was hot. There was no warning light illuminated.

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that while driving at an undisclosed speed, the windshield wipers activated unintendedly, and the washer fluid was continuously sprayed on the windshield. The vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to an unknown dealer, where it was diagnosed with the windshield wiper control module failure. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 04V046000 (Visibility), but the VIN was not included.

The vehicle has experienced ongoing engine performance and safety-related warning events. The first major issue was a single occurrence of an overheating condition that displayed an “Engine Overheating – Idle Engine” warning. After that event, the vehicle was taken in for repairs. Following the repair attempt, the vehicle began displaying repeated check-engine warnings and multiple occurrences of “Engine Power Reduced.” During these episodes, the vehicle lost acceleration ability and hesitated. One of the “Engine Power Reduced” incidents occurred while driving at highway speeds with a passenger onboard. The vehicle was unable to maintain speed and required pulling out of active traffic, creating a safety risk. These issues have continued despite previous service attempts and diagnostics. The warning messages and power loss are unpredictable and create a potential hazard, especially during highway driving, merging, or transporting passengers. There has been no crash, fire, or injury, but the repeated sudden loss of power presents a serious safety concern.

The contact owns a 2008 Chevrolet Colorado. The contact stated that while the vehicle was at an independent mechanic for a service appointment, the contact was informed that the sub frame underneath the vehicle was paper thin due to corrosion. The vehicle was not repaired. In addition, the contact was informed that the independent mechanic had four similar vehicles in the yard with the same failure. The contact stated that the vehicle was recently purchased. The vehicle was not repaired. The manufacturer was made aware of the failure, but no assistance was provided. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 119,000.

In September 2023, when getting my vehicle serviced for a routine oil change, I was told there was a leak in my radiator. They replaced the entire thing under warranty. On November 15th, 2025, while driving on the highway heading home from out of town with my children, an error flashed up saying “steering assist is reduced – drive with care” Upon arriving home, the fan on my car was running on high for a solid 10 minutes after turning the car off. No recall but Special Coverage N252508350 covers the thermostat replacement. Upon inspection by a mechanic, I was informed that the radiator is also leaking again in the exact same spot as it was previously. It should be noted I have never seen leaking fluid in my garage/driveway. I’ve driven less than 10,000 miles since the radiator was replaced previously. If there is a known problem with the coolant system which can cause overheating and steering assist issues, why isn't the faulty radiator and thermostat recalled. The radiator is cased in plastic to aluminum. Plastic can easily catch fire if a car overheats. The casing also prevents an owner from even knowing if there is a leak since the plastic is catching leaks - the mechanic informed me that's why I didn't know about both times it leaked. This is a 4yr old car with 46k miles, twice replaced radiator and thermostat. A recall should be issued since both problems could potentially cause a fire from an overheated engine & loss of steering assist while driving. A google search quickly showed me thousands of other Chevy Blazers from 2019-2021 with reoccurring thermostat and radiator issues. I feel unsafe driving in my vehicle but still owe too much to even trade it in for something else. I've owned dozens of vehicles in my lifetime, used and new and keep them 8-10yrs and have never had to replace a thermostat and radiator. This vehicle is dangerous due to GM/Chevy's cheap radiator model and thermostat which could overheat and catch fire

For the past 2 months every time I reach 40 mph service stabilitrak comes on and the car starts pulling to the left and having trouble accelerating. I have took it to 3 mechanics and they can't find the problem at all

Our OnStar Control Module on our 2025 Equinox started having connectivity issues. It failed to access apps and showed our location 100 miles from where we actually were, and drains the battery. We could not access OnStar to correct the issue. It continued to go off and on, until it completely failed. Researching this, hundreds of 2025 Equinox owners are experiencing the same issues. It is an extreme safety hazard as affected Control modules would send emergency personnel to an incorrect location in the driver is incapacitated in an accident. The module is constantly on back order for weeks. This needs to be looked at
