My oil level drops between changes—should I use a thicker oil?

Check for PCV faults and external leaks. A slightly thicker oil within spec can reduce burn, but it won’t fix underlying wear or leaks.

Will an EVAP code make me fail emissions?

Yes. If a fault code turns on the Check Engine Light, a smoke test will find leaks or a stuck valve.

My 8-speed only shudders after a long highway drive–will a drain and fill fit it?

A noticeable reduction in symptoms may come from this service, but a proper Mobil 1 LV HP fluid exchange typically runs $400–$900 and is the best place to start. Some models also need a software update.

Do I need OEM parts for wheel bearings and sensors?

OEM parts offer the best fitment and longevity. Reputable hub assemblies (often with integrated ABS sensors) from trusted aftermarket brands are usually fine, but ask for a parts and labor warranty.

Is deleting AFM on my 5.3L a good idea?

No. Under U.S. federal law (Clean Air Act), removing or disabling any emissions related device is illegal, even if the vehicle passes tailpipe testing. AFM is considered part of the emissions package, so a delete is not emissions compliant. Many owners repair with updated lifters and continue with proper maintenance.

Common Problems with Chevrolets (and what to do about them)

The five most common Chevrolet issues are oil consumption and Active Fuel Management (AFM) lifter wear, transmission shudder/harsh shifts, coolant leaks, evaporative emissions (EVAP) faults and wheel bearing hub failures.

If you’re shopping or negotiating, confirmed diagnoses and written estimates should create leverage.

Quick checks for the top issues above

Oil level drops between changes or a ticking noise on cold start: Check dipstick weekly on a cold engine, then look for fresh oil around the valve cover and oil pan or drip spots on the driveway.
Transmission shudders or shifts harshly, especially around 35–50 mph: On a gentle test drive, hold steady throttle at 40 mph and feel for rhythmic vibration.
Coolant smell and low reservoir with temperature creeping up at idle: With a cold engine, check the reservoir level and look for pink/orange crust near the radiator or thermostat.
Check Engine Light and rough idle right after refueling: After a fill-up, listen for stumbling idle and ensure the gas cap clicks tight.
Growling wheel noise that changes with speed, sometimes with ABS/traction lights: At low speed, weave gently on empty road; a louder growl while loading one side points to a wheel bearing on that side.

Maintenance that reduces risk for these issues

Stay on a consistent schedule by marking maintenance for the following in the Jerry app:

Change oil and filter on time (or earlier if you go on short trips) to help control consumption and lifter/timing wear.
Refresh coolant at the recommended interval to reduce water pump and thermostat failures.
Replace spark plugs on schedule; misfires can stress converters and transmissions.
Flush brake fluid every 2–3 years to protect ABS modules and calipers.
Avoid “topping off” fuel; a single-click stop protects EVAP components.

If your car’s history is unknown, baseline at 30k/60k/100k miles. Ask shops to combine labor (e.g., pump and thermostat together) and remember that documented maintenance can merit a small premium.

When to stop driving to avoid bigger bills

If you’re unsure whether it’s safe to keep driving, pull over and call a mechanic or tow. Jerry customers have found that new warning lights, severe new noises or smells, or fluids pouring out are all ‘stop now’ signals. Other common situations where stopping immediately is the right move:

Temperature warning or visible overheating/steam
Flashing Check Engine Light with power loss or shaking
Brake warning lights or a suddenly hard/soft pedal
Red oil-pressure light or loud knocking

If you’re using the Jerry app, you can run a quick triage in Diagnose before you tow, then compare price ranges at local shops for the likely repair.

JEREL'S CORNER

I recently worked on a 2017 Silverado that felt like driving over rumble strips while moving with traffic. I took the truck to the highway and kept the throttle steady while climbing a long hill and there it was, the teeth chattering torque converter shudder. I explained to the customer that it was a common problem for this model and that the right way to start would be to go to the dealership for a complete system fluid replacement with Mobil 1 LV ATF HP, plus the latest software update from GM.

It was about time for their next oil change when the customer returned and mentioned the fluid service made a huge difference for about 4,000 miles, but that the shudder was slowly creeping back. They opted for me to replace the torque converter with an OEM replacement to save a little on labor charges vs. another dealership visit since the software update had already been completed.
