SHIFT TO PARK ISSUE

Micro switch for Park is faulty. “Shit to Park” error message. Vehicle is completely disabled and is not drivable.

Shift knob found grounding inside shifter..had to PAY OUT OF POCKET. $1087 TO HAVE SHIFTER REPLACED!

My vehicle will randomly tell me to "shift to park". Happens at least daily. I bought my car in October 2024 I do plan to take it in with my limited warranty. I don't think I should have to cover a rental for however long it will take them to see it happen, diagnose the problem, possibly wait for part(s) to come in them fix it. On top of running the chance it'll happen again in the future and possibly have no warranty as well as rental fees. I think it's very wrong that GM won't recall this and refuses to just fix it all.

loud knocking or banging noises, the check engine light turning on and/or other driving performance issues, such as reduced propulsion cranksaft

I am filing a complaint regarding a brake vacuum pump failure in my 2018 Chevrolet Malibu. The failure of the vacuum pump led to a complete loss of brake assist, making the brake pedal significantly harder to press. This issue directly resulted in a complete loss of braking ability, which posed a serious safety risk while driving. The vacuum pump in these models is camshaft driven, and its failure caused damage to the camshaft. This issue is documented under GM Technical Service Bulletin PIP5835 and is known to affect certain 2016-2022 Chevrolet Malibu models equipped with the 1.5L LFV engine. The brake failure due to this issue could have led to a life-threatening accident, and I am deeply concerned that other drivers may experience this same risk. Despite reaching out to GM and the dealership, goodwill assistance was denied for this known defect. I believe this is a major safety hazard that needs to be addressed immediately. Vehicle Mileage ~120,000 Repair Estimate: $2106 for camshaft, vacuum pump, and related components Incident: The brakes became unsafe leading to a dangerous life threatening driving situation

I was going about 75 mph on the express way with one lane open due to construction. My car started losing power.I heard the chime and upon the dashboard were the words power reduced. My car slowed down in a matter of seconds to around 45 mph. A 18 wheeler was trailing behind me. I quickly jumped in the emergency lane to my right and took the next exit while riding the emergency lane. I shut the car off at the gas station, sat there for about 10 minutes, restarting my car helped temporarily. I was 3 hours away from home and had to drive back unknowingly if I will make it or not. I reached out to Chevrolet and was told to bring it in and leave it but they had no loaner cars for anyone at that time. I have replaced 2 sensors and now my start /stop has quit working. I spoke with 5 visitors at Chevrolet and we all were having the same issues. This is something ongoing according to my research on this particular vehicle and should be recalled asap.

I immediately called and was told to just take it to Chevy/GMC for servicing but was not told why, but just because the engine light was on I was told to go. I couldn’t take an appointment asap because I just started a new job which they also knew. The car has had a recall since 09-06-19 for an engine control module. Which is a serious issue and this car never had it completed and sold me a car with possible engine issue and did not inform there’s a recall on the vehicle for almost 5 years now. I took the car to get serviced at Chevy for the recall on 09/09/2025 and now I am facing multiple issues with the car from it not being done years ago. The recall was N192221960 and it’s major so to sell a car before getting the properly service and I have been financing the vehicle for a year now. Never not once late and I am now being told there’s nothing can be done. I have photos of the car having the engine light pop on the same day u financed this vehicle. Barret knew a serious engine problem was effecting this car for 5 years and still deciding to sell it to me for financing on [XXX]. I need immediate assistance.
