According to Au7o's research across NHTSA recalls, manufacturer TSBs, and owner forum reports, the 2015 Chevrolet Silverado has 4 documented known issues, with 2 rated critical. The most serious are Electric Steering Assist Can Drop Out and Return Suddenly (Recalls 17V-414 and 18V-586) and Reduced Vacuum Assist Can Increase Brake-Pedal Effort (Recall 19V-645). DIY maintenance guides at au7o.io.
On the 2014-2015 Chevrolet Silverado, nHTSA recalls 17V-414 and 18V-586 cover certain 2014 and 2015 Chevrolet Silverado light-duty/1500 trucks. An electrical or software issue can cause electric power-steering assist to disappear momentarily and then return suddenly, particularly during low-speed turning. The change in steering effort can make the truck harder to control and increase crash risk.
Common Symptoms
Momentary loss of electric power-steering assist
Sudden return of steering assist
Abrupt change in steering effort during low-speed turns
Increased difficulty controlling the truck while assist changes
How to Fix
Check the VIN against both recall 17V-414 (GM 17276) and recall 18V-586 (GM 18289), because the campaigns cover different model-year populations. The dealer remedy updates the electric power-steering module software at no charge. Do not replace the steering rack, battery, alternator or ground cable from this card without diagnosis outside the recall remedy.
On the 2014-2018 Chevrolet Silverado, nHTSA recall 19V-645 covers certain 2014-2018 Chevrolet Silverado 1500 trucks with the affected engine-mounted mechanical vacuum-pump design. Pump output can decrease over time as debris such as oil sludge restricts oil flow through the pump filter screen, reducing vacuum brake assist. Drivers can experience a hard pedal and increased stopping distance, particularly during low-speed soft braking, even though the foundation brakes remain functional.
Common Symptoms
Increased brake-pedal effort or hard pedal
Pedal vibration or ticking from the engine compartment
Service Brake Assist message after vacuum drops
Longer stopping distance, especially during low-speed braking
How to Fix
Check the VIN and campaign-completion status for recall 19V-645 (GM N192268490). The recall remedy is dealer reprogramming of the Electronic Brake Control Module so the secondary hydraulic brake boost is used more effectively when vacuum assist is depleted. A vacuum-pump replacement may be separately diagnosed or covered under other programs, but it is not the stated 19V-645 recall remedy.
On the 2015-2018 Chevrolet Silverado 5.3L L83, 6.2L L86 or 6.0L L8B, gM bulletin 18-NA-355 covers 2015-2018 Chevrolet Silverado models equipped with an L83, L86 or L8B engine and M5U or M5X 8-speed automatic transmission. Customers may describe a shake or rumble-strip-like shudder during steady light-throttle acceleration between 25 and 80 mph when the transmission is not actively shifting. GM states that the condition may be torque-converter-clutch shudder but warns that similar sensations can have other causes.
Common Symptoms
Shake or shudder at steady light throttle between 25 and 80 mph
Rumble-strip or rough-expansion-joint sensation
Shudder occurs while the transmission is not actively shifting
How to Fix
Confirm the model year, engine, transmission RPO, production breakpoint and driving condition before applying bulletin 18-NA-355. For an eligible pre-breakpoint vehicle presented with TCC shudder, GM specifies the published one-time fluid-exchange procedure using the correct blue-label Mobil 1 Synthetic LV ATF HP and service tools. If the vehicle returns or does not match the described condition, use normal GM diagnostics; do not assume that a torque converter, valve body or additive is required.
On the 2014-2015 Chevrolet Silverado, gM preliminary information PIT5331 applies to all listed 2014 Chevrolet Silverado 1500 trucks and only early-build 2015 trucks that have a muffler in the compressor-to-condenser line. A small crack or pinhole can form at the inside radius of the first bend near the compressor, allowing oil and refrigerant to spray onto the compressor. The A/C can blow warm and the system may be very low or empty. This bulletin does not identify the condenser itself as the repair.
Common Symptoms
A/C blows warm
Refrigerant charge is very low or empty
Oil or refrigerant residue appears near the rear of the compressor
Small crack at the first bend of the compressor-to-condenser line
How to Fix
Use normal leak diagnostics and verify the line configuration before applying PIT5331. If the leak is confirmed at the described compressor-to-condenser line location, GM directs technicians to replace the line with part 23438932, install support bracket 23264893, recharge to the specified pickup-truck charge and leak-test the system. Do not order a condenser from the former card without locating the actual leak.
