The charging system in my vehicle is no longer working. There's been a recall done for the charging system. It was fixed back in 2013 before long before I bought the vehicle. It's only been nine years since it's been fixed and now it's not working again. I'd like this matter to be looked into as I believe it's faulty at no fault of my own.

I filed a compliant Jan. 25, 2021 (#11389775) in reference to my car stalling. Which has been continuously happening the majority of the time I have owned the vehicle. I was contacted by my mechanic that my problem fits the issues on recall #13V173000 which my VIN # does not pull as a recall. I called GM last year in reference to the same issue which they stated because my VIN was not included in the recall that there was nothing they can do. I have noticed that there are quite a few Buick Lacrosse owners that have the cars that are equipped with this E-assist are having the same problems and are being told that their VIN # are not included. It seems that GM has overlooked a lot of cars that should have been included in this recall. I have had my car for a little over 5 years and my car has not operated correctly due to this issue. I have attached the text message I have received from my licensed mechanic.

While driving my car on the highway the car would completely power down. After sitting in the emergency lane for an hour the car would start and operate as if nothing was wrong. I have had the car for almost 5 years and this has been happening the majority of the time. I have spent over $6000 in repairs with no success.

While driving on a city street at 20 mph the engine started knocking and the service charging system light came on. A few minutes later as I was backing into a parking spot in a parking lot at work the car shut off and would not restart. I had the car towed home and a mechanic looked at it and seen that the engine was hydro-locked which he was able to unlock. After checking the spark plugs, coils, valve cover, timing, oil, coolant, alternator, starter, battery, fuse block and wiring harness, the plugs needed replaced, there was metal shavings in the oil and some type of fluid in some of the sensor plugs on the motor. After replacing the plugs and oil and oil filter and cleaning other components I was driving the car to the store and the malfunction light came on along with service charging system and service stability trak I stopped at autozone to have them scan the engine and the code came back with malfunction with spark plug #3 so I bought a new plug and on the way home about 10 mins after leaving autozone the car completely shut down in the middle of the road. My mechanic came and we were able to get it to restart and get it back home which was only a few blocks. After doing another tuneup and getting it to drive again 2 blocks from my place a rod went right through the front bottom of the engine block which then required for a new engine. I called GM, Buick, the car lot I got the car from and everyone said there was no longer a warranty on the vehicle so the only choice I would have was to pay $10,000 for a new engine not including labor price. My car insurance didn't cover mechanical failures either so I was stuck with a $30,000 car that wasn't drivable. Cause is unknown. I bought this car in Jan. 2015 with 31,000 miles on it and this happened in Nov 2015 with 40 some thousand miles on it. Routine maintenance was kept up to date also.

My 2012 Buick Lacrosses newest problem is one that actually scares me. I can be driving along at 65 miles an hour and it will kinda jerk a couple of times, then usually it will flash 'service the stability track' then I lose power steering and it dies. I'm lucky if I can make it to the side of the road.I live in a rural area and the highways around here are two lane with minimum shoulders. So when the car does this it is dangerous. It has happened 5 times now. It will restart after about 15-30 minutes and drive just fine. I've taken it to a mechanic and nothing shows up on the computer, everything looks good. But its not, this is by far the worst of the problems I've experienced with this car and there have been quite a few.

In 3500 miles my car consumed 4 qts of oil. In returned that caused stalling vehicle shut off while in traffic on a highway and engine damage. GM knows that it's a problem but will only fix the problem if you are under warranty.

Just over 70,000 miles on the car. Engine light came on and car was running rough and stalling at idle. Engine light code indicated a cam shaft misalignment. Dealer tore engine apart to find the problem and reported that a few of the valves were either bent or had broken off. Repair would be a complete engine rebuild/replacement.

Driving my car was just great on my 81st day of ownership it all changed I was leaving a red light in vicksburg off the interstate onto warrenton rd I experienced loss of all power to everything in the vehicle and if anyone is familiar with that road the are hardly any room to pull over so bad that if I had a passenger hey would have to climb over to the driver side to get out or else slide right into the Mississippi river, talk about bad timing with the exception for the radio the vehicle would only click once no abnormal smells smoke or anything that would cause me to think of any engine damage. After hours of waiting the tow truck came checked the car tried to boost it and couldn't get a charge after getting it home I took the battery to the advance auto parts to charge it and they said it was a dead cell so J brought another battery got it home just for it to click still no crank, it's push to start so it was just one single click and the engine light is the only light on the dash that would illuminate. So I called onstar they told me it needed to be taken to a dealer immediately due to a charging issue after taking it back to the dealership they said it's the motor locked up which is obserd due to the fact there was no indication of it doing anything abnormal before it shut down and with it being new I was told it would shut down before it ran hot and mess up the engine and also makes me wonder why it would even be considered because of the fact of the engine protection mechanism. Now the vehicle is at the dealership just sitting there and I have no way to work and still have to pay car note and insurance on a vehicle I don't even have access to anymore. The dealership is dixon auto and body sales and I'm stuck waiting with nothing to look forward to as far as a ride.
