Crankshaft Position - Camshaft Position Correlation

While towing a trailer on 6/26/26, the 6.2L L87 engine suffered a sudden drop in oil pressure, began knocking, and completely lost motive power on the roadway. Because the engine seized instantly, the vehicle experienced a sudden loss of power steering and power braking while managing the extreme weight of a trailer. This combination created a severe and immediate safety hazard, forcing me to maneuver a heavy, unpowered truck and trailer combination through active traffic to the shoulder without full steering or brake control, putting my life, my passengers' lives, and the safety of surrounding motorists at extreme risk. My dad read the codes before we took it to my mechanics and the only…

3.5L ecoboost timing chain failure at only 58,000 miles (code P0016 possible turbo problems TBD Front suspension springs are broken. All of these are common threads on many forums. Ford should be held accountable even though mine is 10 years old, the mileage is the issue. FWIW, they completely redesigned the engine a few years later, but never notified anyone to watch out for these common problems or offer a recall

I have had several codes pop up on my Equinox, such as P0016, P0017, P0089 and P228D. All of these codes are between the Crankshaft position, variable timing position and high pressure fuel issues. I almost wrecked my SUV because of these 3 factors and I have seen thousands of videos on YouTube with other people having the same issues. This is beyond dangerous to be out on the road driving and these codes pop up causing "Reduce Speed" warnings and "Stabilitrak". This will be the 2nd time I've had to replace the Crankshaft position sensor and Variable Timing Solenoid, along with a brand new timing kit that I had put on right after I bought the car over a year ago, that is now in need of…

VIN: [XXX] Mileage: Approximately 103,576 Incident location: [XXX] Safety Complaint: While my wife was driving our 2019 GMC Terrain into a shopping center parking lot, the vehicle suddenly experienced a severe loss of braking assistance. The brake pedal became extremely stiff and difficult to depress, and she was barely able to slow the vehicle. This occurred unexpectedly while the engine continued running, creating a serious risk of a collision. Following the incident, I inspected the vehicle using an OBD-II diagnostic scanner, which identified diagnostic trouble code P0016 (crankshaft/camshaft position correlation). The vehicle also displayed an oil-pressure warning. We subsequently had…

On XXX, I was driving my 2022 GMC Yukon XL Denali equipped with the 6.2L L87 V8 engine, with my [XXX] stepson as a passenger, when the engine malfunctioned and stalled, leaving the vehicle disabled in traffic. The vehicle registered diagnostic trouble code P0016 (Crankshaft Position–Camshaft Position Correlation, Bank 1 Sensor A). Prior to this incident, the vehicle had undergone GM's L87 Engine Loss of Propulsion Safety Recall 25V-274 (GM Campaign N252494000). The vehicle passed the required engine inspection and was cleared to receive the prescribed oil viscosity change from 0W-20 to 0W-40. Under GM's recall service procedure, vehicles displaying P0016 during the inspection were required…

My vehicle, 2023 Tahoe, previously had the GM Recall 25V-274 / N252494001 remedy performed (0W-40 oil swap) in October of 2025. Despite completing the manufacturer's official recall remedy, the engine suffered a sudden, dangerous loss of motive power at highway speeds when I was making an out of state move and traveling alone; it was terrifying. I had to have it towed to the nearest dealership and that is where it is now as I had to leave since I was in the middle of moving. I need a new engine. I have no idea how I will get my Tahoe to my new residence or when. The dealership was not open on Sundays so I had to find a place to stay after leaving my Tahoe full of my items and my bike. I was…

Error code p0016 came up and I started investigating and found coolant intrusion which was a known defect during manufacturing by ford. I was driving normally when the vehicle accelerated really slowly after a stop which could have caused a traffic accident if it happened while in traffic

Our Yukon was taken in for the recall. Dealer did the test and said it passed and used different oil. My wife and kids were driving to [XXX] from [XXX] yesterday. As they exited the highway, the car began acting weird. Then the car completely died. It was towed due to error code P0016. Dealer said they are going to put a new engine in. I saw online that cars with replacement engines were failing too? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
