    2013~2016 Just bought a 2014 CX-5 GX Sport. Any tips?

    Didn’t know Mazda had offered a 2.0L with 6-speed auto combination after the 2013 MY on the CX-5.

    2.5 NA Cracked Cylinder Head with Oil leaking...How common is this?

    Mazda has been up and down in history. The company likes innovation and isn’t afraid to do it. But it’s a hit and miss, and the insisting on rotary engine back in 1960’s almost caused the company if not the Ford came and rescued them. I was in a Mazda dealer in 1990’s with a friend who was...

    2.5 NA Cracked Cylinder Head with Oil leaking...How common is this?

    Don’t buy any aftermarket extended warranty. The compay could fail and you have nothing left. And it has happened too many times before. Just do a “self-insurance”.

    2021 CX-5 Front end thump...Any ideas?

    Thanks for the update. I believe you should at least call the dealer to let them know the problem didn’t get fixed. Another visit to the dealer is better if you have time to do it.

    2.5 NA Cracked Cylinder Head with Oil leaking...How common is this?

    I believe only the original manufacture (Mazda) extended warranty may be worth buying. Your brother can do “self insurance”, saving some money to be used to buy extended warranty, and has some saved money to spend just in case the cracked head happens. Since his 2021 CX-5 Sport 2.5L NA with...

    Coolant Leak Lawsuit Investigation for the CX-5, CX-9 and Mazda6

    For a major problem like the cracked head, I simply don’t believe any reputable car manufactures would allow that 1% failure rate to a new product. Mazda didn’t know the head would crack when they added the turbo and cylinder deactivation with a modified cylinder head on a previously reliable...

    Sport trim? Is it a 2.0L NA with 6-speed manual from Canada? ;) See this thread for your questions: 2014 CX-5 100k service Problem area: serpentine belt tensioner、oil control valve、front lower control arms (bushing and ball joint)、brakes slide pins lube.

    Coolant Leak Lawsuit Investigation for the CX-5, CX-9 and Mazda6

    I hate people are using small percentage as an excuse to dismiss the head crack problem on both 2.5T and 2.5L NA with CD. It’s a major issue and it’d cost an arm and a leg to fix it without warranty. And it’s hard to predict if yours would happen and when it’s going to happen.

    2021 CX-5 Front end thump...Any ideas?

    If you still have new car warranty, take the car to the Mazda dealer for a check since you can produce the symptom consistently. At least you have a record in Mazda’s file if anything happens later.

    2014 CX-5 100k service

    Watch this video in the thread and both LCAs were loose and needed to be replaced at 33,000 miles on a 2020 CX-5: CX-5 Feels squirrelly Read the thread.

    2014 CX-5 100k service

    If the ball joints on the LCAs are still in good shape without play, the worn bushings won’t cause immediate danger other than some clunking noise. But if the rubber seal on ball joints is cracked or broken with play, it definitely is time to replace the LCAs. I went to Brakes Plus to...

    1st to 2nd Gen CX-5 Front control arm upgrade

    Recently I bent the front LCA on passenger side with a hard hit to the curb. CX-5 DIY Control Arm Replacement Difficulty? Apparently Mazda uses different front LCAs for 2014 / 2015 CX-5 and my 2016 CX-5. The part numbers for 2014 / 2015 front LCAs are KD35-34-350S / KD35-34-300S and for 2016...
