Car wouldn't start and been in the dealership for 2 weeks now where purchased due to purchasing a extended warrantee they need to look at it first. after several tech asses the problem they say the timing chain jumped a tooth and engine is shot. car has 66000 miles on it. I purchased with 48K so naturally i bought a extended powertrain warrantee that they say wont cover the cost of replacement due to not having the oil changed every 5K miles. I get it done about 8 or 9K due to using synthetic oils that say they are guaranteed for 15-20K miles. No lights or indication engine issues prior to my wife just trying to start the car one morning.

On January 1, 2025 at about 10:30pm, while driving at about 40 miles per hour the engine made some knocking noises and then suddenly lost power, forcing the car to be pulled over to the side of a dangerous road. When I opened the hood of the car there was a small amount of smoke.  There was no advanced warning that there was a problem with the engine, it just stopped running causing a dangerous situation.  I had the car towed to Infiniti of Massapequa and was told the next day that the car needed a new engine. I was told by the dealer that there was metal in the oil and it appears the main bearing broke. The car is only about 6 years old with approximately 26,200 miles and  has been extremely well maintained with the dealer, including scheduled oil changes with full synthetic oil. I am trying to get Infiniti to cover the full engine replacement cost since the warranty expired about two months ago. However, they still want to charge me $7,560 plus tax. The Infiniti service report is still pending the repair.

My Infiniti started making a slight ticking noise. The next day, the car abruptly stalled out while going down the highway causing the vehicle to loose speed and experience engine failure. Luckily, I was able to steer the vehicle to a more manageable location out of traffic. I had lost engine power and steering. After a certified mechanics diagnosis, the engine was declared blown. The bearings and rods have failed and the engine is no longer in repairable condition. The vehicle was serviced per manufacture regularly and there had been no signs of engine failure to that date.

The engine stopped working. Allowing me to go no faster than 15 miles an hour. The safety issue is you can no longer drive at the speed that you need to drive. especially if you’re on the highway. The problem has been addressed by a dealer. I needed a whole new engine $13,000. The car at 97,000 miles on it. Was well taken care of. No warning signs prior also did not come up on my display Apparently, there are many other 2019 Infiniti QX 50’s that have this issue

Engine acceleartion issue. Rpm goes high but car struggle to speed up.. At first it happened when car was at stop light, struggle to move forward.. took to Grubbs infiniti.. At first,dealer could not replicate the issue, but luckily I had taken the video of the issue I had. Than the dealer was finally able to experience the issue themselves and replaced the transmission thinking that was the issue. I took the car after repair and within 3-4 days I had the same issue. This time I was driving in a freeway at 60 mph. When I hit the gas pedal to accelerate faster,the engine RPM went high but instead of speeding up, car felt like slowing down. So i exited the freeway to service road. Once the speed went down to 20mph, it didn't go any higher than that.This time there was a check engine light on I took it back to the dealership .They again could not replicate the issue and just did the ECM software update. I took the car home but after driving less than 20 miles,the car had the same issue. I again took it back to delearship. This time they are replacing something called VCR..Still waiting now

While driving I heard a roaring noise from my engine and my car’s A/C stopped cooling. I have no warning messages from car regarding the engine. The noise only stops once the car is fully powered off. I recorded a video of the noise and alert panel that shows no warnings/issues. Will be contacting my local service department.
