5.3L Vortec 5300 Engine Oil Consumption
From 2010-2014 GM's Vortec 5300 engine had multiple design flaws that led to an excessive oil consumption responsible for soiled spark plugs, bent pushrods, and timing chain wear to name a few. The problem was compounded by an inadequate oi…
Engine Power is Reduced
Defects with Chevy's accelerator pedal sensor and electronic throttle control system are triggering a sudden and dangerous 'Engine Power is Reduced' warning message which can lead to the car suddenly losing power and having limited accelera…
A/C Condenser Leaking
GM used leaky air conditioners that buckle under pressure in many 2014-2017 trucks and SUVs. Whether it's busted hoses or leaky condensors, thousands of GM owners are showing up to work with sweat stains down their back. It's such a widespr…
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%)

- 2003 Impala security light comes on, won't start 125 (56%)
Another owner is suing GM following their decision to cap the Bolt's battery capacity at 90%, even if that's a temporary fix to prevent fires.
The automaker recalled the Chevy EVs last November after learning that the batteries can spark a flame as they are charging and nearing 100%. By temporarily capping them at 90%, GM can stop those fires while they search for a more permanent solution.
But a plaintiff in Michigan says Bolt owners need to contend with range anxiety and diminished resale value while they wait. Call me crazy, but a temporary restriction on range feels a lot more desirable than a permanently charred engine.…
The combination of cold-weather and a recent software update is diminishing the Chevy Bolt's range by an estimated 33%
according to a new class-action lawsuit. That has sparked some serious range anxiety for Canadian owners. Most EV owners are aware that cold weather is going to slow the battery down a bit, but that problem has been compounded by GM's decision to limit the Bolt's charging capacity to 90%.…
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.
In fact the system doesn't monitor oil levels at all, just the quality of the oil itself. So while the engine may be dry and on the verge of collapse, rest assured that last quart of oil is still in tip-top shape. 👍🏼…
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.…
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.
