Filed Jan 29, 2026 · Acceleration, Electrical · MD

My car was driving along and all of a sudden the steering wheel got extremly tight and the car was hard to steer, I had to pull over turn the car off and the light was still on, I was like 2 miles away from my house, talking to a neighbor that has same car different year, stated to check recall his call did the samething years ago when we had a cold (low temperature) winter and it was replaced by infiniti dealer. I never had any issue with this car until now.it's been really cold. Also this car has issues when it rains, it doesn't want to start, I have check out many videos stating the sunroof leaks or tubes for sunroof gets clogged and leaks into the bcm or ECM system causes damage and dash lights. Im not a mechanic but I know that this is something infiniti/nissian should highly look into. Just a girl,but I know multiple people shouldn't be posting the same concerns on their cars and it's not being looked into

The contact owns a 2014 Infiniti Q50. The contact stated that while driving at various speeds, the message "No Key Detected" was displayed. The contact waved the key fob around the START/STOP button, and the message ceased. The contact stated that the light around the START/STOP button was orange, but was green before the failure. One day, while driving the vehicle, the engine failed to shut off after shifting into park(P) and pressing the START/STOP button. The contact made several attempts to turn off the vehicle. The message to "Visit the Dealer" was displayed. The vehicle was taken to several independent mechanics before finding a mechanic who was able to turn off the vehicle by removing the starter fuse. The mechanic advised the contact to tow the vehicle to the dealer. The dealer performed a water test and discovered that there was a leak in the sunroof, which had caused the failure. The mechanic discovered that water had leaked through the firewall in the body control module (BCM), causing the failure. The contact was provided with an estimate, and the vehicle was repaired. The contact stated that after the repair, while the vehicle was idling, the vehicle intermittently jerked. There was no warning light illuminated. The manufacturer was not notified of the failure. The failure mileage was approximately 150,000.

A short in the hybrid system's fuse relay caused the air conditioning control unit and compressor to fail. This further shorted out the hybrid junction box causing the hybrid battery recharge and power management system to malfunction. Gas mileage was very adversely affected and the hybrid system would have eventually failed causing a potential safety issue where the vehicle could lose propulsion suddenly while driving.

Engine has rough idle while in park. Even after the following maintenance was done. Replacing spark plugs, engine software update, coolant flush, power steering flush, fuel system clean, new mass air flow sensors both sides, serpentine belt, all new gaskets on top part of engine, valve cover, intake manifold, spark plug tube seals. Flushed rear and rear diff and transmission. Steering is heavy to turn. The colder it is outside the worse the engine shakes. Throttle response is delayed at times. Transmission shifts hard the worse the engine shakes. Colder it is the slower the windows roll up and down along with the wipers. Engine drops RPM when turning wheel while in park. When driving engine drops about 100 - 200 RPM then keeps going back up under acceleration but causes transmission to shift hard. This problem causes the output shaft seal to break and rear wheel speed sensors were replaced. After a sharp turn car hesitates to accelerate even if hard on the gas. Extreme cold temps outside make the engine almost sound as if something inside engine internals is not right. Hot and humid weather makes it run the best. No check engine light problem started at 90,000 miles now im at 126,000 miles and still no fix and no check engine light. Loss of engine power. Even going up the smallest hill incline maybe a couple feet over a distance of maybe 3 blocks engine downshifts to 5th gear just to maintain 70mph even though I can be going 50mph in 7th gear. Car jolts forward when coming to a stop as if the output shaft is still spinning at a different speed than the engine. Can cause an accident if not fixed. Other infiniti cars seem to have the same problem. Even the g37.

Vehicle would not start and determined that battery was dead. Arranged for jump start (through my roadside assistance program) but vehicle would still not start. Had vehicle towed to infiniti dealership. They figured out a way to charge car (wasn't accessible via front hood since a hybrid) and found a way to open truck to direct access and charge battery. Upon car starting, various error codes appeared. Car dealership had no knowledge of what they meant as they had not seen them before. I contacted infiniti corporate and they associated the codes with a previous das voluntary recall. However, upon further investigation by dealership, it was determined that das update was already applied. To determine the root cause, I was told it would require the car to be partially disassembled. As two of the codes points to a braking system issue, and one to the chassis system, I wanted to verify if this is a safety issue and if a recall is needed. (see attachments for reference)
