r/mazda6

I have a 2015 Mazda 6 Touring with 291,000 miles. After owning it for several years with no issues electrically my keyless entry has stopped unlocking my doors. It happened randomly after I stopped for gas during a roadtrip. Got out and locked it using the keyless entry but when I came back out from the store the car would only lock using the keyless entry. Same lock signals like the flashers flashing once and the single beep but just wouldn’t unlock. I’ve always used the keyless entry and it usually functions as one tap lock and beep once and then another tap would unlock it and beep twice. The key fob unlocks the car fine. I’ve tried checking to see if the fob was in low power mode, it wasn’t. I changed the battery on the fob about 2 months ago and changed it this morning as well and it hasn’t fixed anything. I’ve tried resetting the fob by switching the car from on to off from the drivers seat 4+ times and then holding the lock and unlock button with it responding correctly but that also didn’t fix it. I have yet to disconnect the battery or replace the actuator in the door yet due to it just happening yesterday. Any tips or advice would be useful. Thanks!

Right.

For the love of God why is this car such a walking issue?

I bought this car at 72k miles - mazda maintained 1 owner.

4k miles in i had a p0401 error code. I instantly thought its the egr decarbon issue.

Garage thought the same. They did the egr and manifold clean and a dpf clean too. Ok.

Then the stuttering didnt go away as it was misfiring badly. 2 injectors came back faulty - ok. Sorted and copper washers also installed.

Then on a long drive it gave underboost error code - garage said the turbo actuator and solenoid was gone. Ok got that fixed.

Car now ran fine - but again after motorway ride it gave a thud when coming down to 40mph and lost power. Now the error code is p0101 - MAF / air flow issue.

Garage said they did a smoke test earlier so not an air leak.. i am lost what the hell could the issue now be? It went from no issues at all to this. I did drive it 500miles with broken exhaust pressure sensor / pipe as I didnt know it was gone at the time, however this was long time back and was fixed. That exhaust pressure sensor pipe was also flushed this tine during decarbon work.

Garage said it could be a camshaft issue?? I cant wrap my head round it ..canshaft would normally cause misfiring all the time .. it ran beautifully until the thud when coming down from motorway to lower speeds and gave the error code p0101.

I am losing hope and MONEY on this ... any help or guidance please. The garage said they are calling a specialist soon.. but i am losing hope on this crappy car now. I loved it and now i feel sh*t to even have bought it.

Thanks in adavance.

Hitting 80k, thinking about replacing the tranny fluid at dealership/ mechanic. Don't want a flush. Can they replace the whole fluid thru only a drain and fill and replacing the filter? Or can only be a partial replacement of fluid (50% or so)? Thank you.

The dealer I bought my 6 from replaced the wiper blades during their "used car prep" and put some Bosch blades on it. They work fine but the driver-side blade flutters at the end of it's travel and it's kinda annoying. I'm a stickler when it comes to blades too. It looks like these use an uncommon attachment so there's not lots of options either. My favorite blades are Trico Force but they're not available for this model, if I'm not mistaken.

What do people use / like on theirs ? Are the factory wipers really good, just okay, bad ?

Noticed after going through the carwash that the trunk tail lights collect and hold water.

I removed the lights and plan to seal them with clear silicone, but I'm not sure where the main points of entry are normally.

Any suggestions would be appreciated.

Year: 2017

Trim: GT

Im cross shopping a Gen 3 (2018-2021) Mazda 6 against the 2016-2020 Lexus ES and saw a few options available. They’re pretty rare unfortunately compared to the Lexus but a strong alternative in my opinion. There’s a few available near me and I wanted opinions on what would be better.

1. 2021 Carbon Edition with 66k miles for $20,300

2. 2018 Signature with 80k miles for $17,700

3. 2019 Signature with 58k miles for $22,000

I like the Carbon Editions styling and the fact that it’s the latest model year available with the most recent feature, tech, and updates. However I really would like the Signature’s added luxury and refinement especially as an alternative to the ES.

The Carfax for the 2019 is kinda questionable with body electrical being repaired and the battery being replaced twice in just 60k miles. The 2018 has an extensive maintenance history with only the fuel pump being replaced around 55k. The 2021 has a good maintenance history as well but 4 reported owners though only 2 owners are shown as actually putting miles on it. Let me know what you guys think.

As above. I drive a 6 with the 2.2D engine. It is the sport nav with 175ps and the twin turbo set up.

I keep getting a SCBS forward malfunction pop up on the dashboard which is originally caused by a P0101 error then causing a cascade of ECU errors (ABS / SCBS). Always causing limp mode and sometimes producing a check engine light.

The error occurs under engine braking conditions only with no throttle - if I keep very light throttle then the error doesn’t happen.

I have done the following work in chronological order:

Full decarb - originally fixed issue before it started happening

again after ~5k miles

Found and fixed boost leak from turbo

Replaced MAF sensor

Replaced EGR with new gaskets.

Replaced MAP sensor

I’m still chasing this same issue and starting to pull my hair out. I’ve also ran a live diagnostics on a run and when the error occurs both the MAP and MAF values are within tolerance.

Other than this the car is perfect, the engine runs absolutely mint, pulls lovely, drives lovely, no rough idle, no coughing or spluttering, 0 smoke at all.

It has very regular oil changes and I also regularly check oil level for dilution which isn’t a problem either.

Please someone help!!!!

Hey guys,

I’m finally getting some of the necessary work done on my Mazda 6 GT. I’d appreciate some recommendations for parts and services. I need a break job, including pads and rotors, spark plugs, and a new drive belt (is it the timing belt?). I plan to buy the parts and take them to my local mechanic, but I’m also considering taking it to Mazda to get all these services done. Which option would be more cost-effective?

Yes, I understand that I shouldn’t have delayed these tasks, but money was scarce for a couple of months. However, I’m planning a long road trip in my car and want to ensure that everything is in order beforehand!

Thanks!
