2018 Mazda CX-5

Defective sealant used on timing cover, already leaking engine oil at 85000km… also confirmed as the same engine prone to cylinder head cracking from poor casting dimensions resulting in engine oil contacting the exhaust manifold and smoking. Possible fire hazard. Engine can seize up from low oil pressure at highway speeds and lock up the wheels causing an accident. Not sure why Mazda hasn’t issued a recall for this obvious safety concern… reminds me of Hyundai/Kia engine problems and now they’ve been sued and replacing thousands of engines for free.

Engine seems that it cracked. The car has 66K and has good maintenance record. I took my 2018 CX5 to Mazda for a possible oil leak. Mechanic says block has hairline crack, is leaking oil down exhaust manifold and engine needs to be replaced. It seems a known issue with this model & Mazda is aware of the problem. There is no recall or class action lawsuit that either of us found. Mazda has said this car in no longer under warranty. It has 66K and the engine is broken?

The issue started happening [XXX]. I was driving home and the car went into limp mode. Several errors came on the heads up display and on the dashboard. At first I could not go faster than 31mph, then it dropped down to 17mph, then to 7mph by the time I got home. 1.When accelerating from a stop light, car goes into limp mode and won’t accelerate almost stalling in the road. You must pull over, turn off the car and wait 5 minutes so error clears so you can drive again. 2.Car goes into Limp mode when going up a hill 3.Between 46-48 mph, car hesitates when accelerating 4.Between 56-60 mph, car hesitates when accelerating 5.Error Codes received per Lake Car Care: P2299, C1001, B1303 I brought the car to Lake Car Care and they replaced the spark plugs and coils as the codes said it was a misfire on Cylinder 1 & 2. This cost me $ 947.57. This did not fix the problem. The mechanic Todd took the car for a ride and it went into limp mode for him also. He could not figure the issue out after having the car for a couple weeks so suggested I take it to Mazda in Clermont. Mazda has had the car twice for over 2 months now and cannot figure it out. They replaced the ABS Module for $ 1284 which did not fix the problem. Replaced the injectors for $ 1426 which didn't fix the problem. They did a fuel compression test which came back fine and cleaned the catalytic converter which they said was clogged and this didn't fix the issue either. It is unsafe to drive this vehicle on the road as it does not accelerate so it is putting myself and others at risk. Mazda corporate has been called and case manager has been assigned but has been NO HELP to me at all. Photos are attached of all error messages, text messages with Mazda, repair receipts, etc. August 9th, Mazda told me they are at a loss and don't know what else to do, I haven't heard from them since. Please help. I am at a loss and don't know what my options are. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Burnt oil smell started being noticed in the cabin. Checked for leaks and none was found. Took the car to the dealer and it turns out the cylinder head is cracked. Dealer acknowledged this is an ongoing manufacturing issue. I contacted Mazda corporate to see if I qualify for after warranty assistance. No engine lights are on. Car has been maintained properly.

I bought this brand new in 2018 (Aug.) and I take care of this car very well. I was in the Korean Army, and I worked at the motor pool taking care of cars and trucks. Last year, I noticed my oil level decreasing that I kept refilling. I just thought it was burning some oil. Last week, I was losing lots of oil with some smoke (oil burning). I took the car to a local shop and they said "the cylinder head appears to be leaking oil from the back drivers side of the head".

I noticed a burning smell while driving. Smoke started coming through the air vents and made me light-headed. I asked my son to take a look, and he said that oil was dripping onto the exhaust and smoking, and it could have caught on fire. There were no warning lamps or any other indicators besides the smell and smoke. I could have passed out from inhaling the smoke and died, or my car could have caught on fire. I took my car to the Mazda dealer. They confirmed that my car was affected by the well-known 2018-2021 CX-5 cylinder head crack. They quoted me $4848 to fix it. When I asked if they could help me with the price, they offered me 10% off. I told them that’s unacceptable. After much back and forth with the dealer and Mazda Corporate, they dropped the total to $1470.60.

The car (2018 Mazda CX-5) exhibited a strong burning smell coming from either the engine or exhaust which you could smell in the cabin. No warning lamps turned on in the dash indicating any problem. Problem was recreated by Mazda dealership service center and diagnosis is that cylinder head is cracked and is leaking oil into the exhaust manifold. Suggested repair was a replacement of the cylinder head. Was told this is out of the 5 year/60K warranty. Had car for 5 year 11 months and only driven 45K miles. Car has not been inspected by anyone other than Empire Mazda of Huntington.

2018 mazda started smoking from under hood and noticed a burning oil smell. Took to mechanic and was told engine head gasket has a huge Crack. Car only has 22k on it and never been in any accident. All appropriate preventative services are up to date. There was no indication light no warning light nothing to identify why the car was leaking oil and smoking until it was looked at. This has multiple.complaints in regards to this specific year and model and needs to be addresses before someone's car catches fire or stalls in the middle of highway
