I remeber I started it with checking on a VIN check website to see if my car is for recall then I emailed the dealer who luckily confirmed it. Well it shouldn't be a big hassle, in my case they set up an appointment and fixed, wish you good luck!I have the exact same problem. 2020 CX-5 Signature. I bought it 6 months ago. only 5800 km on it. This morning. the battery is dead !!! wow.. Then I came to this page and discovered that this is a known problem. I wish I knew that before buying this car. I just called the dealer .. I think I am about to spent very unpleasant time with this issue.
That's good to know! Here North of the border, it was 0°F this morning and my new to me (6,000 miles demo) CX-5 had no squeaks or rattles driving on rough roads; I'm also impressed how the doors close with a reassuring thump and all body panels are perfectly aligned. It provided enough heat but it took some time before the temp gauge reached normal; however, I'm sure it's better than in a CR-V...I've read that to solve the oil dilution by gas in cold climate they reprogrammed the ECM to allow the engine to get warmer at the expense of the occupants comfort. Many loyal Honda customers are not happy; there's a class action lawsuit about their 1.5L turbo. My wife had a 2008 Civic coupe and it was the most reliable car she ever got, looks like things have changed.After having four Hondas with multiple problems in the last few years including one that would have legally qualified as a lemon had I not got rid of it, I remain very impressed with my MX-5 after a year (zero problems) and CX-5 (PLG unit caused dead battery). The CX-5 has also had the fewest rattles of any of the 30+ automobiles I've owned. All of them generally started out quiet, but tiny annoying noises (that I'm very sensitive to) always started within a few thousand miles. The CX-5, so far, has been an impressive exception. I still look forward to driving my Mazdas. I can't think of a brand I've been more satisfied with. Given my history of frequent trades, I may not own the CX-5 more than year or two, but I'm willing to bet it will be remembered as one of the most problem-free and enjoyable automobiles I've owned so far.
Do you have a 2020 CX-5? In what trim level?That's good to know!

I had a trouble free 2014 Murano and stupid me, I traded in for a 2017.5 to get all the latest goodies but it was a lemon. No way I was getting another Nissan even if the 2021 Rogue is a vast improvement; "once burned twice shy" as the saying goes (or something like that English is my second language)!
I have a Canadian 2020 CX-5 GS which is similar to Touring in the U.S. At idle in drive once warmed up, it's so smooth and quiet you would think the engine is not running!Do you have a 2020 CX-5? In what trim level?
Looks like Mazda finally resolved the vibration issue in cold weather due to the inferior new liquid engine mounts used on gen-2 CX-5.
Oil changes are well known to cause all sorts of problems.… it worked fine before and the only thing I can see that changed is that the dealer did this update on 9/8/20 while it was in for an oil change....
The remote start doesn't make it meaningless at all. While it may be the reason that I noticed it in the first place, the behavior that I suspect changed-- the ability to unlock the door with the car running and the fob outside of the car-- can be be duplicated without using the remote start at all. This is why I asked if someone who hasn't had the update can verify how it works.Oil changes are well known to cause all sorts of problems.
But seriously, IMO the aftermarket remote start unit makes any comparison to our non-modified vehicles fairly meaningless. And no, I have not read any other report like what you posted.
I don't know if you're aware that a portion of the locking functionality can be changed by the owner, by following specific steps which are outlined in the Mazda documentation. I have not studied these modification options in detail, because there's nothing I feel needs to be changed with the way the system works now. However, given that your system has now become messed up, perhaps this capability might be a way for you to make things operate the way they used to on your vehicle.
I had this issue with a brand new CX5 in 2020 that died overnight even when no electronics were on. Dealer was initially clueless, researched this forum and found the rear liftgate issue and relevant bulletin. My 2020 CX5 model production code matched the bulletin and only after I spoon fed them all the info they agreed and replaced my rear liftgate module. Completely fixed the issue.Hi,
New member here looking for some insights into a mysterious electrical draw that’s causing my battery to go dead overnight on a new 2020 CX 5 Signature. It seems to happen when I pull the car into the garage at night. No lights or accessories are left on, nothing, such as charger, is plugged in and the car is turned completely off not left in accessories mode. The car has been at the dealer for a week. They couldn’t find any abnormal electrical draw and the battery was in normal condition. Apparently the 2020s have some type of wifi modem for future functionality and the service manager thought it might be seeing my house WiFi (recently installed a new / stronger house WiFi router) but they checked and the device on the CX 5 is in the correct inactive mode. They were telling me they couldn’t find anything. I pressed them to keep looking and then they found a recent service bulletin about a potential issue with a rear left gate electronic that might draw more power than normal when the car is off but they were talking miliamps and I am uncertain that extra amount is enough to drain the battery overnight. The left gate electronic part is on back order. I also asked the dealer to test parking it with objects in front and behind to assess whether the parking sensors are staying active after it’s turned off. It’s been a big downer on a new top of the line Signature we spent $40k on. Anyone heard of this type of issue and what the solution might be? Thanks guys.
Does anyone know if this problem persists in the 2021 model? I have a 2021 CX-5 Signature that was purchased in December 2020. This afternoon, I tried to start my car and found that the battery was completely dead. Nothing was left on or open. I drive the car every week. The car will be inspected on Monday by the dealership.
