Filed Jan 27, 2023 · Engine, Transmission · PA

Car has had excessive oil consumption since start. Easily consuming 1-2 quarts of oil on monthly basis. Had timing chains replaced at 75000 miles. Car suddenly stopped without warning 1/16/23 and completely shut off while driving. Now, at 170000 miles the engine is blown, due to chains loosening, and valves getting bent and scattered.

Technical Service Bulletin #13-06-01-003H (TSB 003H) in regards to GM’s 2.4L engines & excessive oil consumption. This release not only concedes a persistent issue found in at least six GM models, but more importantly fails to acknowledge the serious and fatal risks as a result of the Oil Consumption Defect. As a direct result of GM's known defect, I was left in a dangerous situation. I crossed a divided residential street, engine stalled and the vehicle turned off, stranded in the middle. It is not unreasonable to imagine other similar situations occurring, leaving people directly susceptible to serious injury or death. Here, the dipstick was completely dry. It took two quarts before any oil appeared on the dipstick. The oil light did not illuminate and I was approximately 1500 miles from my next scheduled oil service. The diagnosis: pistons excessively worn from lack of oil, engine failure. My situation is not unique. https://www.carcomplaints.com/Buick/Verano/2012/engine/engine.shtml Sanchez et al v. General Motors LLC, found in favor of the plaintiffs. The issue: the Oil Consumption Defect, found in 2010-13 Equinox & Terrain, both vehicles listed on TSB 003H with the 2012 Verano. https://www.classaction.org/media/sanchez-et-al-v-general-motors-llc.pdf The primary cause: faulty piston rings and defective crankcase ventilation system, leading to excessive oil consumption. The oil monitoring systems are defective. “Reliance on the [system] instead encourages owners to drive with a false sense of security.” “Problems include, but are not limited to: unanticipated engine shutdowns, engine stalls.” “[This] is a substantial safety concern because [failure]… cannot be reasonably anticipated or predicted.” To allow GM to ignore this documented and persistent issue, without further investigation, would be a failure carry out the federal safety agency’s core duty: to save lives and prevent injuries. Thank you.

My 2012 buick verano has stalled out and died several times while driving on highway and when accelerating from stops. My verano has 64,000 miles and is well kept and maintenanced but continues to stall over and over. I have seen several complaints from other 2012 verano owners who have experienced the same problem and have come to the conclusion that gm has sold us a faulty product that can cause death or a serious injury. Being that I am a individual who lives paycheck to paycheck I cant afford to throw money into a 7 yr old car with less than 70,000 miles that im still making payments on and I hope that gm will be held accountable for selling a faulty, dangerous vehicle that is not safe to be on the road! Please investigate before someone is killed!

Ses light periodically keeps coming on beginning at 49,000 miles in 2015. It is always regarding problem camshaft position actuator solenoid/sensor code: p0014. It came on again last year at around 82,000 miles and then came on again 10 days later. Last year dealership mechanic at least knew something about engines and some parts to change instead of just letting a computer tell him what parts so changed timing kit and water pump kit for loose chains. Human fix was not the end of the problem either as same problem happened this year nov-13-2018 at 92,000. Usually when it happens vehicle runs rough when idling or stalls out on accel, blocking the roadway until you can get the vehicle in motion again. This year did not stall out but made funny tapping noise on accel/decel and almost all of the oil was gone, yet the "low oil light" never came on. Ses does not come on until it's almost too late. Seems like the problems are felt or noises heard the slower the vehicle is moving. With as often as this problem occurs, I now believe some other part must be make the camshaft solenoid go bad when the replacement parts are also going bad. Maybe the entire engine needs to be recalled if gm cannot determine the problem.

I was at a stop sign and when it was my turn to go I started to drive and realized my car was not accelerating, I had the gas peddle all the way to the floor as a tractor trailer was fastly approaching my rear bumper, luckly I was able to coast to median. Took to dealer and they said there was a switch that needed to be replaced. My entire dashboard lights and radio went out, which dealership had to replace twice. My car shut off while pulling into a parking spot, it was raining and defrost was not working, took to dealership which they stated it was my battery, paid $200 for a new battery. My car jerks and stalls when I am going from a complete stop and begin to pick up speed. I was backing out a parking spot today and my car shut off and the check engine light came on, I restarted my car which the check engine light remains on and the stalling and jerking continues. These issues can cause a major accident and if severe enought can be life threatening. If I am required to hold up my end of the bargain by paying my car note the manufacturers need to be held accountable for their end of the bargain which is providing their buyers with a secure and reliable vehicles for families.
