The Least Reliable Chevy Models
Some models just can't seem to get out of their own way. We've created a list of the least reliable Chevy models using data such as complaint volume, average cost of repairs, age of the car when it breaks down, and recall frequency. Here's the worst of the bunch.
What Owners Complain About the Most
Sometimes it's easiest to just tally up all the complaints and see where the biggest stacks are.
- 2005 Trailblazer fuel gauge not working 225 (100%)
- 2002 Impala passlock problem, won't start and security light is on 224 (100%)
- 2004 Impala speedometer gone haywire 187 (83%)
- 2007 Suburban excessive oil consumption 186 (83%)
- 2002 Impala intake manifold gasket failure, leaking coolant 142 (63%)
- 2005 Cobalt power steering failure 128 (57%)
- 2003 Impala security light comes on, won't start 125 (56%)

Toss another lawsuit onto the ever-growing pile of GM Vortec oil consumption cases. The Missouri based class-action is the latest in a series of suits saying the 5.3L Vortec engine churns through oil because of defects in the low-tension piston rings. The problem is compounded by GM's questionably designed oil life monitoring system which doesn't warn owners when oil levels get dangerously low.
GM may have used the wrong bolts to secure the seat belts in certain 2020 and 2021 Chevy models. Could the new bolts work? Maybe. But when it comes time to rely on the seat belts, it's better knowing the right parts were used to tether them to the frame.
Chevrolet has recalled 460 Bolt EVs to fix leaky front-left brake calipers. The automaker believes the calipers weren't cast properly, allowing them to leak during hard stops. Losing brake fluid is never great, but the real concern is that the caliper could eventually fracture and no-one enjoys a sudden loss of braking power.
General Motors has been sued for last month's Bolt EV recall which temporarily limits the battery's capacity to 90%, bringing the car's range down from 238 miles to roughly 214. The plaintiff says the software update is giving him "range anxiety" and that's only heightened by the impending cold weather months which can also limit range. Last I checked, winter was going to happen regardless of the recall and it could just be me but I'd be more anxious about the possibility of my car catching on fire than losing 14 miles of range.
A judge has granted GM's motion to dismiss one of the cases alleging the automaker should reimburse C7 Corvette owners for cracked and warped wheels. The lawsuit claims GM is breaching its warranty by blaming any instances of cracked wheels on owners driving habits. But the plaintiff made a few key mistakes:

Have a complaint about your vehicle?
The best way to find out what's wrong with a vehicle is from the people who drive them. Not only do owner complaints help us rank vehicles by reliability, but they're often used to spark class-action lawsuits and warranty extensions. Plus, they're a great way to vent.
