The vehicle has sudden loss of power due to the failure of the intake rocker arm vvt oil control valve. GM has halted production on this part with no viable solution or replacement option. GM P#12633613. This issue has happened multiple times in the past 6 months
The engine light came on. Took it to my mechanic. He told me that the valve rocker arm oil control is bad. He told me I am the 9th in the que just from lansing area and the part is back ordered since August 2019. He ordered the part from shaheen Chevrolet. I called the GM help line. Initially they were very helpful but later they called me and said they can't do any thing. The car is standing outside on the road and I am paying the insurance and just paid the registration. The defective part numbers are 12633613 and 12634467 (gasket + part). GM case number is 9-5813783154. The person who took my call was thanna and the date I called was 2/13/2020.
Chevrolet did a terrible job creating a engine then discontinuing parts to it. The rocker arm oil control valve is a known failure point on this vehicle and they discontinued it.
I been trying to order part 916806 this I've been needing it for a while a variable valve timing solenoid I feel like I been ripped off because no one been able to get this part has this part been replace as another part what am I to do I need my car. I can't get my admission done to get my plates
I have been waiting on the intake rocker arm control valve since December 2019. Apparently GM has discontinued this part for Malibu and Impala. They are saying it is on back order. I am still paying on my vehicle and this should be apart of a recall. There is thousands of us that is waiting on this part and this is so unfair. I am terrified that something else is going to happen to my engine if this is not fixed soon.

The check engine light came on and the code reader showed that the variable timing solenoid needs to be replaced. After searching for a replacement part, I keep getting told that this make/model consistently has this problem. The engine light comes on, the car loses power and seems to have a tugging feel when driving especially when accelerating. This happens both with in town driving and freeway driving. Happens at any speed.
The contact owns a 2014 Chevrolet Malibu. While driving 30-40 mph, the vehicle hesitated and stalled and restarted independently. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic where the contact was informed the rocker arm control oil valve needed to be replaced. The vehicle was then taken to white-allen Chevrolet parts (442 N main St, dayton, oh 45405 (937) 222-3701) where it was also diagnosed that the rocker arm control oil valve needed to be replaced however, the parts were on back order. The vehicle was not repaired. The manufacturer was contacted and informed of the failure. The failure mileage was 46,000.
My vehicle shows the check engine light, the dealer made a check and found problems with the rocket arm valve part number 12633613 (engine variable timing oil control valve). That was in December 2019, they request the part to GM, and so far the part is unavailable. I tried to buy it through internet and friends in other states, and no auto parts have this part. This part is necessary because control the timing of the engine. My car can get ruin if I do not change that part. GM is being irresponsable to have this important part of the car available.
Engine code P16D0 causing a valve that controls air to oil intake for the motor is stuck open causing in accurate oil pressure. This happens when in motion. To continue to drive would most likely cause extreme engine failure and improper gas mileage. After checking the code and replacing the "affected" parts, the light is still not cleared as it creates more issues within the motor. The dealer is not able to identify the issue and is charging an absurd amount of money just to attempt to fix the issue with out any guarantees. There are also an abundance of similar situations and it all occurs once these vehicles get to 100,000 miles. This is a serious issue and I believe the manufacture should correct such an issue as multiple people have been experiancing the issue.
Have been needing a repair but the part has been unavailable for months. We need the oil control valve and part number 12633613. GM does not know when the part will be available, so no way for the car to be fixed.
The engine light is on and at times the car loses power! trying to get parts since October 2019 was told no one is contracted to make the part and GM has not been helpful !!

We purchased this vehicle as for safety and convenience, we are student and full time workers. We share one care and because of that we took care of the car like recommended. Since October, we have been isolated, depended on uber and lyft because of GM not having the part for the vehicle. We searched everywhere, we called GM and filed a complaint, nothing was done. We paid to get the diagnosis done and said we need the oil control valve and part number 12633613. No one has it and everyone is looking for the same part. There is an issue there and GM should be held responsible. We're still paying for the vehicle. The incident had while the vehicle was in motion, as I was driving to work, I heard a loud pop and lucky I was to my job 21880 state road 7, boca raton fl 33064. I parked the vehicle and went out to check, oil leaked everywhere leaving a trail behind. Called my insurance for road side assistance. We were able to purchase the off market brand which didn't last even a month! now we stuck. Thank you Chevy,
Vehicle has had failed oil arm rocker valve (part# 12633613) since October 2019. GM has advised they do not know when this part will be available, and has no other resolution to provide except to wait and that they are sorry for inconvenience. Check engine light illuminated means it will not pass emissions testing in ct (or state inspections in a lot of other states). Car is not usable because of this, some power loss issues being experienced at highway speeds. GM has not offered any resolution other than $2500 off a new GM vehicle. Will not assist further and state that there is no eta for replacement part. Car not serviceable and GM will not resolve.

Engine light keeps coming on while driving or stationary. I had a diagnostics test done they said it is the rocker arm solenoid. They said there is a national back order and 1 of our local dealers had 6 cars waiting for this part at the time and had already been waiting for several months. This is obviously a manufacturing defect that GM should be doing a recall for.
