2018 Toyota Camry: misfire or rough idle

Filed Oct 8, 2026 · Engine · WI

My 2018 Toyota Camry LE went into Limp mode while drive on the highway causing jerking while driving and tons of error codes on the dash, and issues with safety systems shutting off and accelration. After towing to a dealership, dealership gave me the following description of the defect: Coolant is coming through the cylinder walls due to a hairline fracture in the cylinder causing 2 of the 4 cylinders to misfire and coolant to mix with usual contents. We aren't able to identify where the cause of this problem is but it makes the most economical sense to replace the engine with a lower mileage engine and replace the neighboring parts to support the less old engine. I was quoted $8300 approximately. the same vehicle just a few years older are recalled already for the exact same thing - the federal safety agency Recall 20V064000. the federal safety agency Recall states: "The subject vehicles are equipped with a 2.5L 4 Cylinder engine (A25A) and may have been produced with engine blocks containing higher porosity levels. Higher levels of porosity could create cracks in the cooling passages, resulting in coolant leaking internally and/or externally. This may lead to engine noise, engine smoke, warning lights/malfunction indicator illumination, an audible chime sounding, and/or, in some cases, engine overheating and possible internal mechanical engine damage (e.g. seizing of internal engine components). If engine overheating or internal mechanical engine damage were to occur on involved conventional gasoline vehicles, a vehicle stall while driving at higher speeds could occur without prior warning to the driver, increasing the risk of crash."

I keep getting error code P0304 which says its cylinder 4 misfire the engine starts shaking a bit and most of the warning lights in my dashboard turn on and it disables the parking brake , I took it to a shop and they took out the fuel injectors to visualy inspect them and moved injector 4 to a different cylinder but the same error keeps coming back cylinder 4 misfire , I keep having to spend money and still have the same issue. It only does it on a cold start .

1. On entering freeway, car did not respond to accelerator, & seemed to lose power momentarily. Then seemed to engage, accelerating. 2. On freeway, gas pedal became spongy, car coasted for a couple hundred feet, then pedal engaged, car accelerated. Occurred three, 3, times, different trips. 3. On turning right, on city street, engine started to run rough as tho it would stall. Worked itself out and continued w/o further trouble. 4. On two occasions, engine ran roughly when turning it on in front of the house. Weather was warm, not a factor. Ran smoothly after a block. Gas pedal again felt spongy while car ran rough. Dealer has stated that (1) "try using name brand gas" (tried; no change), (2) for probs 1 & 2 above, "it must be the new transmission." now received fuel pump recall notice, but toyota has "no remedy available"?! This is unsafe - pease help!!

There has been an open recall on my car for months and toyota has not came up with any type of remedy to fix this issue. 'the subject vehicles are equipped with a low-pressure fuel pump which may stop operating. If this were to occur, warning lights and messages may be displayed on the instrument panel, and the engine may run rough. This may result in a vehicle stall, and the vehicle may be unable to be restarted. If a vehicle stall occurs while driving at higher speeds, this could increase the risk of a crash.' sounds pretty dangerous and this is the car I travel with my kids in, I am extremely disappointed in toyota brcause this was once listed as the safest car on the road.

There has been several misfires when starting the car, and the car sometimes goes into like an idle mode. The dashboard states 27 mpg, but I've been tracking mileage on a paper log, and the vehicle is really only receiving approximately 19 mpg. I looked to it to see what it could be, and after looking up active recalls, realized that it was symptoms of the fuel pump malfunctioning. I took it to scott clark toyota; a manufacturer's dealer, and they refuse to remedy the situation.

Often during acceleration, my car seems to sputter or misfire. When taking off there seems to be, as the only way I can describe it, an air bubble in the fuel line. Kinda like fuel isn't constantly being fed to the engine. There are gaps. While driving at a constant speed, this does not happen. Also, sometimes when accelerating from a stopped position, my car accelerates slowly and then all of a sudden, takes off as if its playing catch up. Although there isn't an active recall on my car, I think there is a problem with the fuel pump.
