Infiniti QX60 loss of power problems

Filed Sep 8, 2026 · Transmission · CO

While traveling at 75 mph(speed limit) on the interstate, the vehicle's CVT transmission suffered a catastrophic failure and suddenly lost all power/acceleration, dropping into a low-gear limp mode. No engine light appeared until after we parked. This caused an immediate and dangerous drop in speed in high-speed busy traffic, nearly causing a severe multi-vehicle collision. We put our hazards on and continued at about 20 mph until the first exit nearly a mile away. This happened during mountain interstate driving with large distances between towns where most have no dealerships. We were able to get to a mechanic/gas station just off of the exit who ran the codes and told us that the transmission will have to be replaced and he had no means of doing it as well as any other location with in about 150 miles. I had the vehicle towed to the closest Infiniti dealer at a cost of $1,015. Was then told that a replacement would be needed at over $9500. This is a luxury brand (Infiniti) and is only a 2020 QX 60 with 72,000 miles. Warranty was until 70,000. Definitely by any measure a premature defect. Told by service advisor that CVTs are a real problem in the QX 60s due to not being able to handle the weight. 2022 and younger no longer use CVT. Infiniti extended warranties on the same car from 2015-2018 years and currently 2019-21 in a lawsuit Ross vs Nissan North America. Traveling with an [XXX] mother, myself and wife. Luckily we were not stranded in the middle of nowhere. Trying to geta goodwill from Infiniti but they are not considering the perfect maintenance records, timely transmission fluid services and all work being done at the Infiniti dealer previously. I had brought up concerns about the transition from park to drive seeming delayed in engagement multiple times over my 3 year ownership of the vehicle and was never fixed or seriously looked beginning at one month of my ownership and the 59,000 transmission fluid exchange service. Never an engine light. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATIO

After going through a touchless car wash with undercarriage spray and clean, the vehicle stalled 5-10 minutes later. This occurred after the wash was completed and driving away. Suddenly the engine began to lose power, stumbled, and then died while driving. If I had to guess this was a sensor or some electrical component that may have been affected by the water spray from underneath. There were no check engine or other warning lights when this occurred. Attempted to restart the engine. After a few seconds longer than normal it started and appeared to run fine. Drove it home afterward. If the water caused the issue there are serious implications for driving in rain, through puddles, or snow as that water can migrate up into the engine compartment during driving (would be especially dangerous at highway speeds). If it makes any difference, the vehicle did idle fine for a few minutes after leaving and stopping outside the touchless car wash. Only after a walkaround, removing trash from the vehicle, and then driving away did the stall occur.

1. Airbags and seatbelt lights: The vehicle airbags light and seatbelt lights keeps flashing and after taking it to the dealer, they keep suggesting buying a new passenger seat assembly coasting thousands of dollars. Many similar complaints online with no resolutions or temporary solutions by the dealers. 2. CVT transmission problem: Vehicle jerking, and hesitating when driving. Vehicle also struggling to find the right amount of power. Dealer installed new transmission for free under extended manufacturer warranty. Problem is still there and has gotten worse. Struggling to accelerate or even lose power. Vehicle not in a drivable state with significant safety issue. Dealer insists there is nothing wrong after 3 subsequent visits after the first transmission installation. Vehicle pretty much totaled due to main component failure.

While driving, the vehicle displayed an engine malfunction warning followed by a low oil pressure warning. I pulled over and waited. The oil level was checked and was not empty. The warning lights briefly went out, but shortly afterward the engine lost power. When attempting to restart the vehicle, the engine began knocking. The vehicle became inoperable and required towing. This was a sudden engine failure with no prior indication of oil loss, leak, or neglect. This created a safety concern due to sudden loss of power while driving.

I have a 2020 Infiniti QX60. While driving on the interstate I75 the check engine light came on and the car lost power. This was very dangerous as it could have caused a very serious accident. Had to have car towed to dealership. Was told that the transmission needed to be replaced at a cost of $8,600. This suv has only about 75,000 miles. Upon checking the internet I found that this transmission issue has been a problem for a number of years and Infiniti has not adequately addressed it. This is a safety issue and Infiniti should take ownership and fix problem.

As The vehicles drive it will intermittently lose power. This is continuous problem ever since 2 weeks after I purchased the vehicle. The power loss can last for 1 sec or most recently up to about 3 to 4 secs. The other day I had to pull over after the vehicle lost power and wait two minutes before starting back on the drive. When it loses power, the power steering goes out and if approaching a turn and/or a decent curve in the road, that can be very hazardous. I Believe this is a huge safety concern and many people have experienced the same malfunctions.

A mechanic says it is PCM failure. I have owned the car for 18 months. Shortly after buying it, it started doing this thing where it loses power for just a second or two. Cruise control and proximity sensors kick off, steering wheel locks and/or power steering turns off, all interior components turn off. Usually everything comes right back on, and I can reset the cruise control. Lately it has been more frequent, and things don't go back to normal. It sometimes causes the vehicle to stall and not start as well. Today even once things are back "on", I can't control the AC fan, radio volume, etc. Bluetooth shows connected to the car on my phone but isn't playing through the vehicle speakers. I don't undersrand how this could not be a recall when it poses a major safety risk to suddenly lose power and be unable to steer the vehicle! This has been happening since Feb 2024, so I'll just put the original date. Sometimes it happens 15 times in a day and the vehicle is more or less not drivable. Other times I'll go a month or so with no glitches.

I am reporting a serious safety failure involving my 2014 Infiniti QX60 Hybrid (VIN: [XXX] ), tied to Recall R21B4 / the federal safety agency 21V‑774. Although the recall was marked complete before I bought the car in 2022, the defect — sudden loss of power — occurred again while I was driving at highway speeds. Infiniti is refusing to assist due to age/mileage, despite clear evidence the recall fix was ineffective or incomplete. Diagnostic codes confirm hybrid system failure (P0A08, C1A1A, C1130). I am requesting a full investigation into Infiniti’s handling of this recall and a resolution for my unsafe vehicle.

This vehicle has ~43k miles and in the shop 3 times. Once I had computer issues and was replaced, and twice now to replace the fuel pump. First instance, I was at a stop sign and tried to accelerate but the car wouldn't move. It was like it was in neutral but was in drive. I had to shut car down, restart and was able to get to the dealership. Second time, I left work driving ~73 mph on [XXX] in Jacksonville Florida when out of nowhere I could feel the gas not taking. I then got a flashing message across my dashboard several times that said "Engine Stalled" . Imagine the fear in the middle of the highway and essentially having no gas power. Fortunately, since I was leaving at noon, it was not rush hour and fortunately this occurred right before an exit. I was able to remain calm and not panic and get over two lanes in time to pull off to an exit ramp all the while de-accelerating until I landed in the grass off the exit ramp. I cross [XXX] every day for work and cars losing power going 75 mph on [XXX] is terrifying and could easily lead to a wreck and in the most unfortunate incidents on that bridge; cars hit have gone over the side. Again, second time now they are supposedly replacing the fuel pump. How can two be bad? This is so dangerous for someone to be put in this situation. I have seen other posts on the Internet with fuel pump issues on the 2023 QX60 and similar circumstances. Car is in the shop now so don't have the receipt yet for the replacement.
