The contact owns a 2016 Chrysler 300. The contact stated while driving at an undisclosed speed, he heard an abnormal clicking sound coming from the engine compartment. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed failures with the connecting rod bearings and hydraulic roller lifters. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 180,000. The VIN was not available.
The drive shaft broke and had to be replaced. This resulted in lack of stability prior to the break and mobility was comprimised after it broke. The car was repaired at Wayne's Precision and Transmission auto repair in Bumpass, Virginia on November 4th, 2022. The state of Virginia requires annual car inspections which we will have due next June. Symptoms prior to replacement of the drive shaft included clunking/knocking noises from underneath the car when the car was in motion. Modest noises first occured in August, three months prior to replacement, and proressively got worse until replacement was necessary.
Driving the car under normal load,s tarted to notice a knock from the engine. Over the next few weeks it progressively got worse. Pulled plugs, checked oil. Gas, put a boroscope down the spark plug holes looking for engine damage. Finally had to have the car sent to the shop. When they got the motor torn down the bad lifter was discovered. Upon seeing that & doing some research there are quite a few posts on forums about the mds lifters on the 5.7 & 6.4 hemis going bad & destroying a cam. I have had oil analysis done on most oil changes through out owner ship but this wasn't picked up on from the last one. Not sure if it went out quick & destroyed the cam or if it had been happening for a while. Car only has around 75000 miles.
The lifters in the car are ticking and sticking. Dealer quoted $3500 to repair. I have had this car for 3 months.
Engine first started making a knocking noise then after about two weeks , engine made a loud cracking noise , then a presentence constance knock engine light came on had the code checked came up as a misfire on the #1 cylinder. Had a tune up done knock got worse . Was informed by a mechanic of the possibility of a timing chain / camshaft problem called chrysler was informed that the recall p01 doesn't apply to my VIN , my vehicle is a canadian manufactured car
While driving at highway speed (70mph), the oil pressure suddenly dropped from a normal 55+psi to about 15psi and the engine started to vibrate bad and run eradically. Slowing down and stopping, it felt like it was going to stall making it much, much harder to steer the vehicle and slow down due to the lack of vacuum created by the engine to assist with the power brakes and RPM's needed to provide power steering assist. Oil pressure dropped to about 5psi at idle. No knocking sound from the lower end of the engine, just valvetrain tapping/ticking. This vehicle needs towed. This is a low mileage vehicle-well under 100k miles and documented care. There are many, many hemi equipped vehicles on the road and at dealerships that have these related timing chains breaking / timing chain tensioners breaking and failing, camshaft and lifters grinding themselves away but, very few are reported as either tsb's or recalls. This is potentially a very deadly and dangerous issue and should not be taken lightly!!! Extremely dangerous!!!
Camshaft / lifters are prematurely wearing out( wiped ) the car is throwing a p0300 ,p0303 code but the spark plugs,coils etc are fine ..engine shakes and knocks while driving the smell of gasoline is evident lose of power while driving only 88000+ miles
