'B' Camshaft Position - Timing Over-Advanced or System Performance

My 2019 Chevrolet Colorado, equipped with the 3.6L LGZ engine, recently triggered a P0024 diagnostic trouble code. This code indicates a failure of the Bank 2 exhaust camshaft position actuator solenoid, a critical part of the variable valve timing (VVT) system. After researching, I discovered that General Motors has issued Special Coverage N232430470 for this exact issue on the 2020 Chevrolet Colorado, which uses the same LGZ engine and solenoid system. Despite the identical failure and engine design, my vehicle is not currently included in the coverage. I believe this reflects a systemic defect that affects multiple model years — not just 2020 — and that GM is choosing to limit coverage…

TL* THE CONTACT OWNS A 2018 CHEVROLET TRAVERSE. WHILE ATTEMPTING TO TURN INTO A PARKING LOT, THE CHECK ENGINE INDICATOR ILLUMINATED AND THE VEHICLE LOST POWER. THE VEHICLE WAS TOWED TO HAMPTON CHEVROLET (757-325-9604, LOCATED AT 1073 W MERCURY BLVD, HAMPTON, VA 23666) WHERE THE TECHNICIAN PERFORMED A DIAGNOSTIC TEST AND FOUND CODES P0014 AND P0024. THE MANUFACTURER WAS MADE AWARE OF THE CODES AND ADVISED THE TECHNICIAN TO CLEAR THE CODES AND RETURN THE VEHICLE TO THE CONTACT. THE TECHNICIAN ACTED ACCORDINGLY. THE CONTACT STATED THAT THE MANUFACTURER AND THE TECHNICIAN STATED THAT THERE WAS NO REMEDY FOR THE FAILURE. THE CONTACT INSISTED THAT THE VEHICLE WAS NOT REPAIRED AND UNSAFE TO DRIVE…

WHEN I AM DRIVING OR WHEN I START MY CAR EVERY TWO WEEKS OR SO MANY MILES THE ENGINE LIGHT WILL COME ON. AFTER DRIVING SO MANY MILES OR A DAY LATER THE ENGINE LIGHT WILL GO BACK OFF. THIS HAS HAPPENED 10 TIMES SINCE PURCHASING THE CAR. I AM TAKING IT TO THE DEALERSHIP ON MONDAY TO FIGURE OUT WHY THIS MAY BE HAPPENING. THIS IS $150 JUST TO GET A DIAGNOSTICS TEST DONE. I HAVE HAD A DIAGNOSTICS TEST DONE ON THE CAR PREVIOUSLY WHEN THIS FIRST HAPPENED FOR FREE AT AN AUTO STORE. IT THREW THE P0024 CAM SHAFT CODE. I'M ANXIOUS TO FIGURE OUT WHAT'S HAPPENING.

I have trouble codes that occasionally come up even after vehicle has been serviced. The vehicle used to drive fine. Now it started miss firing. I was told the problem was coming from the engine compartment/sensors. An OBDII diagnosis detects a problem with B Camshaft Position Timing Over Advanced or System Performance Bank 2 (p0024). I fear that without the fix, the miss firing can cause an accident. The engine light is illuminated when this happens.

The contact owns a 2020 GMC Canyon. While driving 65 MPH, the check engine warning light illuminated. The vehicle was taken to the dealer and DTC: P0024 was retrieved. The dealer determined that the camshaft solenoid bank #2 needed to be replaced. The contact associated the failure with Special Coverage: N232430470 (Camshaft Position Actuator Valve Solenoid - Bank 2 (Left Side) Exhaust); however, the vehicle was not covered under the program. The manufacturer was notified of the failure by phone and suggested that the contact report the issue to the NHTSA Hotline. The failure mileage was approximately 57,800.

The component that’s failing on my truck is the Apple car play and a check engine light (CODE P0024) which indicates Exhaust Camshaft Position, Bank 2. My safety and others safety is put at risk while having these issues: 1.) The Apple Car Play, having to take my focus off of driving to try and unplug my phone and plug it back in to HOPEFULLY fix the issue of using the navigation or phone calls while I’m driving during long road trips is extremely dangerous for myself, my loved ones and others on the road around me. 2.) This error code is extremely unsettling to experience while 500 miles away from home and has caused an incredible amount of stress on multiple occasions. The light constantly…

…DEALER HAD VEHICLE FOR 1 WEEK, AND WHEN ASSESSMENT COMPLETE, REPORTED DTC P0011, P0014, P0021 AND P0024 CAM CODES. THEY VISUALLY INSPECTED WITH NO CONCERNS, TEST ACTUATOR SYSTEM OPERATING.

What component or system failed or malfunctioned, and is it available for inspection upon request? Multiple components in the engine timing and transmission system have failed. These include: Camshaft actuator solenoid valve failed twice (at ~30,000 and ~60,000 miles), each time with different DTC codes. Camshaft positioning sensor failed, triggering P0024 (“timing advanced and bouncing around”). Timing chain tensioner spring failed, requiring re-timing. Camshaft carrier case gasket experienced a major oil leak at 59,000 miles. Thermostat failed. Battery was replaced, but no diagnostic testing was performed—only code clearing. At 82,000 miles: Torque converter has failed, transmission fluid…

Just prior to 8/1/22, check engine light came on. They found P0014 set, lack of power, rough idle. They found oil pushed through bank 1 cam solenoid actuator and had to replace on 8/1/22. Check engine light came on again in mid August 2023. Found P0024 code and had had to replace the cam actuator again. This time GM has part on backorder, like they are fixing systemic issue with part. They could only replace by getting from another dealer. Still charged me for part even though it was just replaced 12months ago. Would like to know if this is a systemic issue with GM.
