  1. Intake noise?

    This one is kind of hard to describe, but I'll give it my best.... Over the past 3 week or so I've noticed a "sucking" sound is the best way to describe it at low RPMs. I hear it before I hear the turbo start to spool up. Once I start to hear the turbo spool this sound goes away. I looked at the...
  2. Low fuel economy

    I’ve noticed in my 16 regal gs AWD that I’m only getting 17mpg on average. I switched to running only 93, put a new air filter in, replaced and aligned all 4 tires as well. I plan on changing the spark plugs next weekend but I’m not sure why else my MPG is suffering. Any ideas? I have about...
  3. Jack recommendations

    Went to change my oil in my new regal for the first time and realized my 3 ton jack from habor freight is too big to fit under it! It’s served me well with the LaCrosse but I suppose I have to buy a new one now. I was looking at the low profile 3 ton steel jack at habor freight but was curious...
  4. Spark plugs

    Which spark plugs are you guys using in your regal? I peeked into the suggested maintanance and it says to do the spark plugs soon. Rockauto is showing AC Delco Iridium 41125. Are these the OEM plugs they come with out of the factory?
  5. Key Fob

    Got home late tonight and pulled my '16 GS into the driveway to park. Shut the car off and started walking towards the house like usual and tapped the lock button on the key fob. Nothing. Tried several more times, nothing. Got into my car and tried to start it. "No remote detected". Very...
  6. Front License Plate Holder Removal

    Have any of you removed the front license plate holder on your regal? I bought my GS in Ohio which requires it but I live in PA which only has a back plate. I hate the look of it and would love to remove it but don't seem to know what these connectors are. Are there plugs you can buy to fill in...
  7. Regal trunk

    So I recently purchased a used 16’ GS and never really gave the trunk much of a look. I find it strange that the speakers are exposed on the roof of the trunk. Is this normal or am I missing a cover? Picture attached below:
  8. Losing oil

    I was replacing an air filter on my wife's car (14 Verano 2.4) and decided to quickly check the oil level. To my surprise the dipstick was dry. I had an oil filter and oil on hand so I did an oil change on the spot. To my horror, when draining the oil only 2 quarts came out (takes 5). I finished...
  9. 3rd Gear

    I just recently purchased a used 2016 Regal GS AWD. After driving it for a couple weeks I've noticed that 3rd gear seems to be acting strange and I was curious if it's just part of this car or if I should be investigating it. It seems to me that 3rd gear tends to "drop" in at weird times, or...
  10. 2016 Regal GS

    I've read several posts on here regarding certain issues associated with the regal GS, but I'm curious if there are any 2016 owners on here that can share to issues of that model specifically. I'm looking to retire my 2010 Buick LaCrosse at 225,000 miles for something a little more fun, this red...
  11. System too lean

    Hey all, I finally got my 2 new cats put in, as well as 4 new oxygen sensors. This obviously fixed the P0420 code, but now I'm dealing with some new ones. My code reader is showing a P0171 and P0174 which is system too lean on both the front and rear banks. The car does not idle very smooth...
  12. Cylinder 4 misfire

    Hey all, Got in my car this morning to a very unhappy engine. Started the engine and immediately noticed it was idling very rough. I noticed the CEL blinking so I pulled out my scanner and saw the P0304 "Cylinder 4 Misfire Detected" code. I gave the car a little gas and it immediately started...
  13. 2014/15 LaCrosse

    Hey all, I’ve been shopping around for a new ride recently and found a couple 14/15 LaCrosses that look nice. I’ve had the 2010 LaCrosse for a while now (215,000) miles and still running. I do a lot of driving for work and decided to get one with lower miles soon. For those that have a 14/15...
  14. Weird Window Issue

    2010 Buick LaCrosse CXL AWD - 211,000 miles So here is a weird one: A couple weeks ago a message came on the dash that said "Open, then Close Driver Window". So I did, several times, and the message went away. Since then the message pops back up every couple minutes while driving the car and I...
  15. Problem with the rear window shade

    Hey guys, here is a weird one for you. For the last year or so, my 2010 Lacrosse CXL has had rear windshield shade issues. When I put the car in reverse, the rear shade goes up. When you push the button to put it back down, it will wind down until it hits the bottom and then go back up again...
  16. Whining Sound Coming from back of car

    Hey guys, question for you. I have a 2010 buick lacrosse 3.0 V6 AWD CXL with about 130,000 Miles on it. It's most noticeable when I first start the car in the morning. I hear this loud whining noise coming from the driver side back tire area. (I haven't pinpointed the exact location but...
