Engine consuming oil with no leaks. Tech said that oil is passing through rings and burning during combustion. My car has 174000 miles and has been well cared for. I am very upset that the remedy for this is to overhaul or replace the engine. Also, A/C doesn't work anymore. Tech says compressor has failed. Please remedy. Last american car I buy.

My car stalled while driving home from work on the freeway, almost causing me to get hit by the car behind me. The car had been running fine, there were no indicator/warning lights flashing on my dash prior to this. I and it towed to a mechanic close by and he told me it looks like the timing chain had broke. I bought this as a certified car and have always had the oil changed as soon as the vehicle information lamp indicated it was due.

Replaced engine a 2.4L laf and transmission a 6T-50 with bad trans @ 149K miles on 2011 Buick Regal. Replacement is 2011 2.4L laf engine and 6T-50 trans w/ 17K miles. Car now has P0089 and P228D codes and whine from high pressure fuel pump as described in #pip5203A. Turns out original engine is a 2010 engine with all the cam chain issues seen in other NHTSA complaints. To add insult to injury my dealer tells me ECM can not be reprogrammed to 2011 because programming is driven by the VIN# only. My only choice is to buy the parts from GM (about $1000) to turn my engine back into a 2010 engine or pay a dealer several thousand dollars to do the work. I`M in a position of paying several thousand dollars more for the car then it is worth. This was to be my retirement gift to myself, guess I will be driving my 1997 Pontiac Grand Am until I drop dead. Thanks GM, my brand loyalty sure pays off. My advice to future car buyers, buy another brand!! P.S. I hope this constitutes some emission violation and the epa hits GM with a multi million dollar fine. P.S.S. it dies on the road to.

Regal

  • 73,500 miles
When at a stop sign my vehicle died. I was able to restart it but at slow speeds it continued to die. On the way home, at highway speeds the car performed fine. At slow speeds the rest of the day and during a test drive the next day, after about 10 minutes, the vehicle died almost continuously, losing power steering etc. To get home I had to keep a foot on the gas while braking/turning and stopped to keep the idle speed up. I was able to get it to the dealer the next day. The diagnostic check revealed a P0010 failure code from which they found the intake camshaft actuator solenoid was shorted. They replaced it and currently it is operating fine. They indicated it was not covered under warranty and not subject to the specific vehicle recall that I received.

When driving or coming to a stop or even making a turning the vehicles shakes and then shuts off, this first happen when I was driving the car on a very busy street, the first time this occurred it happened with no warning just a shake and then the car shut off, reducing speed rapidly, causing the traffic behind me to do the same, thank god that there wasn't an accident, but it sure could have been. And now I see on the forum that I am not the only one with this problem, Buick isn't doing anything about it, does this fall under the lemon law, help

There have been issues with the engine starting which is apart of a class suit but has not been solidified. I am angered as to why my car keeps not starting when in position. I have to try to start my vehicle several times before actually starting. Now I take it in and its still an engine issue which they said it was the camshaft. My local dealership has no loaner vehicle and im now without a vehicle. So upsetting.

I first got my car with 20K miles on it. Drove it for a month and the stability control warning came on. The car stalled and I had to restart it, only for it to do it a couple more times. Very scary!!! this needs to be taken care of, as I bought a lemon! took it to the dealership as it was under warranty and they said they fixed it. Happened again a few months later! apparently they didn't fix it. GM needs to identify the problem and recall this, as I see more and more complaints of the same thing! class action needs to be filed otherwise.

My brake pedal is sticking causing my car to stall and my cruise control not to work, I have to manually pull my break pedal back up after I use my brakes while driving. My car is also just dying with no warning, while driving down the interstate. My lights, and radio will stay on when this happens, but my air conditioner and engine will cut off. It has happened over a handful of times in the last 3 weeks, it's gotten to the point that I am scared to drive it anywhere.

Regal 4-cyl

  • 47,000 miles
While approaching an intersection at approximately 35 mph my 2011 Buick Regal with less than 48,000 completely stalled out. No warning at all. All the lights were on in the dash including a stabili trac. Light and a message that read engine power reduced. I then blared my horn and cruised thru the intersection on a red light thankful it just turned red and opposing traffic hadn't started across yet. I was finally able to stop the car that had absolutely no power steering and ABS was turned off and shut the car off. I waited a few minutes until my nerves calmed down and restarted the car all the lights were off except the engine light. Drove the car home and called the dealership, who then had it towed to them. By that time the computer restarted itself and no check engine light was on, with that no reading as to what the problem was at the dealership and I was left being looked at as if I didn't know what I was talking about. This happened approximately 3 months ago and I have had the same problem a total of 3 times since then. When is Buick going to step up to the plate and finally do something about this" are they waiting for someone to be killed first? I've read this same problem with the same car numerous times on numerous sites...where is our help???"

Regal

  • 70,000 miles
I have owned my Regal since 2011. As I accelerate the car would shudder and shake, then I would get a service stabilli trac message followed by a message stating that the engine power has been reduced. After I have the issue it will reset itself after restarting and then will run fine for a while. I called on star on several occasions and they told me that it has an engine misfire or the stability trac needs to be serviced or the electronic throttle body is malfunctioning. I have taken the car to the dealer and they tried to fix without any luck. I think part of the trouble with fixing it is the fact that the computer resets itself and therefore they can't find a code. The other issue with trying to fix is the fact that the car only has the issue when it is 35-40 degrees outside and below. Other issues I have had, driver's seat heater not working, outside trunk release not working, passenger side seat belt does not connect properly and of course the recalls for the driver's seat bolt and exterior turn signals. Now for the bad news for myself is that the car is out of warranty. Given the fact that I have read many similar complaints and most of them not being resolved, I find it very hard to bring myself to take it to the dealer and have them guess to what the fix may be at my expense.

Regal

  • 56,000 miles
While driving down the road yesterday, at around 50 miles per hour, our 2011 Buick Regal, with only 56,000 miles on it, lost power out of the blue and would not drive over 30 miles per hour. It apparently was in reduced power mode due to a faulty throttle body. Thankfully we were not on the expressway, as this would have been a very dangerous situation given the roads were very icy yesterday. Apparently, many 2010 - 2012 Buick Regals are covered for this with a special coverage adjustment so it is a known problem. We believe our vehicle should be included in this adjustment as well. As I mentioned earlier, this could be a very dangerous situation and we believe it needs to be addressed.
