2014 Infiniti Q50: loss of power steering

Filed May 9, 2021 · Electrical, Engine · TN

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.

Today november 6, 2019, at about 12:30 pm after I started my vehicle the steering was very hard to steer and maneuver. I drove the vehicle back home but had a hard time steering. My vehicle has adaptive steering. I called about a recall that was issued for this problem and was told a software update was made in july of 2016. It appears that this has not resolved the issue and my vehicle may lead to a possible crash if I drive it. I was told that the issue was resolved despite the fact that I had an issue today. The weather was about 36 f and I don't believe it was a weather related. Issue. I was parked at a shopping mall at the time it occurred the vehicle was still warm when I started the vehicle.

During 20 degree f, I drove my car with no issues to a retail store, parked it in a parking lot. After shopping, returned to my car & started it up, put in reverse, started backing up, then several malfunction lights lit up on the car's dash & the steering wheel locked all of a sudden. I could not turn the steering wheel. I could only move the car forward & backward & this is all while the car is powered on. I had to have the car towed to the dealership. In past history, there has been 2 other steering recalls (electric power assist system & adaptive steering parts) on this same make/model,& year. The dealership service team told me on 1/22/19 & the issue with my car was the chassis control module (the brain of the steering wheel) & a lane departure malfunction & the cost of repair is $1600 (not covered) despite I have an extended warranty. The chassis control module as the brain of the steering wheel clearly relates to the previous steering recalls (electric power assist system & adaptive steering parts) along with the lane departure malfunction as diagnosed by infiniti dealer in suitland, maryland. The description of the previous 2 recalls (electric power assist system & adaptive steering parts) say that in freezing climates, the engine compartment reaches freezing, disabling the power steering system, resulting in a loss of steering, increasing risk of crash. As diagnosed by infiniti, definitely the chassis control module & even the lane departure technology parts have not been included in the previous steering recalls & should have been. Please issue steering recalls for the chassis control module and lane departure malfunction parts or just the entire steering system. Infiniti is fixing my car at no charge to me after I told them about the related previous steering recalls. Per the internet, many people have experienced this with this car model. Danger!!

Steering failed completely approximately 8/12/15 while on the road. Incident occurred while at a slow pace and I was able to force steer the car to the side of the road. Today I went to start the car in my garage and once again the car had no steering.dealer was able to fix the problem however I feel that this is a major problem that could be dangerous. For instance, if my wife had been driving in the first incident she would not have strong enough to steer the car to the side of the road. Coast infinity in sarasota, fl 941‑924‑1211 today the steering failed again but occurred when I started the car in my garage. Was not traveling at the time.

Das steering failed again. This was recalled several times in 2013-2014 for the same problem. Dealer and manufacturer "rectified" problem 3 times. Steerlng seizes up when temperatures fall below 0 degrees. Steering failure and chassis failure come on. Car required towing to dealer each time last year. I was able to get it to the dealer this time, with difficulty, no power steering and steering wheel is 90 degrees off center. Dealer provided a loaner as they had previously. This is still a dangerous problem that infiniti has not resolved.

After having a great experience owning a '04 infiniti g35x, I purchased an infiniti q50 in mid october, 2013 in dallas, tx. In addition to software issues with nav & apps, I have had problems being able to unlock or start my car w/o my key fob. Three times I lost steering control when the weather was near 32 deg. F... Twice in driveway (reported to infiniti in my survey) and once while driving and then I wouldn't have been able to swerve if necessary (very dangerous)! Restarting the car alleviated the problem each time. After receiving a "service campaign" notice I took my car to the dealership. The service mgr. Said that he hadn't heard of any problems with the das, but I had the recall notice in my hand and my sales rep told me that she was having the same problem. This past weekend I visited a car show and spoke to an infiniti rep. About this das issue. He told me that the das issue was related to cold weather and that the servo-actuators that make up the das system need to be sealed. When we asked if that meant putting grease or silicone on a rubber boot, he said no. The units had to be replaced with new ones. He said that any software fixes for the das would be to correct the lack of triple redundancy in the event of failures. I just asked the service rep. If they replaced the servo motors or control units that are the root of this problem and he said that they weren't required to do so. I think that the dealer and infiniti are being very ambiguous about the extent of this problem. I'll give them one chance to fix these problems and if not satisfactory, I'll try the lemon law!

Q50s hybrid with tech package driving less than 2 weeks (380 miles). Before delivery, the dealer confirmed that the car does not have any recalls pending and software is up-to-date. In the early morning, I drove about 60 minutes without problem (it was below zero), and parked the car for 2 hours in outside parking lot. When I started the car again (outside temp approximately 0 degree f), engine started but multiple warning came up. Those include "master warning, power steering warning, vdc warning, and forward emergency braking system warning." I tried to back the car from the lot and it moved, but the steering was extremely heavy and I could not turn. I restarted 3-4 times but nothing changed. I called infiniti and they set up towing but I needed to wait for 90 minutes for pick up due to cold weather. While waiting, I kept the engine on since it was cold outside. After the engine running approximately 30 minutes without shutting down but still all warnings on, I again shut off the car and restarted. This time, all alarms disappeared, and steering was normal. I contacted with dealer, and was notified that same problems are happening with other q50 same day, and nothing needed to or can be done at this moment, since all software is already updated. Of note, the car was previously kept in location colder than 0 degree f many times and this problem did not happen at the colder temperature. But only difference this time was the car was kept outside parking lot. Since that incident, no further alarms appeared and the car is running fine. However, as I see more information in this site, I feel some sort of manufacture or official investigation needs to be initiated, since it seems there are multiple same issues happening everywhere. Some of these incidents could have easily triggered fatal accident. Obviously, after a fatal accident then one cannot complain anymore...

Purchased new infiniti q50, drove the car for 3 weeks for a total of about 900 miles. One day I started the engine an attempted to drive out of parking lot, steering wheel was difficult to turn. A message appeared on dashboard stating "warning chassis control system error - see owner's manual". Three other lights appeared on dash board, one with a steering wheel and exclamation point, another with a triangle with an exclamation point, and a third with a picture of a car with tire skid marks. Drove home slowly called infiniti. They had car towed to dealership where it was purchased. The dealership said this is a known issue but claims only 3 cars they sold are affected. 2 days later new software was released by infiniti and the update applied to my car. Took car home. 6 days later drove car to work, attempted to leave work, same problem occurred, no power steering, same lights and messages on dashboard appeared. Drove car to dealer, while issue was present so they could see it first hand. Was told by same service technician that issue is not widespread only 3 cars affected. Talked to internet sales manager at dealer he said he got 5 calls for the exact issue that same day. Both days issue occurred, air temperature was approximately 0 degrees fahrenheit. Dealer attempted to provide a brand new q50 as a temporary loaner. Same issue occurred with that vehicle before leaving the dealership parking lot. Spoke with general manager at dealership, he indicated he was aware of problem and advised I call and open a case with infinti consumer affairs, which I did. He said he is continuing to sell these cars as infiniti has not told him to stop. I advised him to stop selling the cars before an accident occurs from the power steering failure. Seems to be the same issue as existing recall, but was told by dealership's service manager my car was not part of the recall.

Tl* the contact owns a 2014 infiniti q50. The contact was driving approximately 25 MPH when the power steering assist failed, causing the steering wheel to seize and become unaligned. The power steering and traction control warning lights did not illuminate until after the failure occurred. The vehicle was diagnosed by the dealer as the steering software needing an update. The contact was also advised that the vehicle was not included in the federal safety agency campaign number 13v588000 (steering) in which she experienced the same defect as listed in the recall campaign. The manufacturer was notified and no solution was offered. The failure mileage was 950.

Direct adaptive steering became extremely stiff while backing out of parking spot after sitting overnight at zero degree temperatures. Multiple restarts did not remedy the situation (chassis control system error remained illuminated). Ended up towing the vehicle to the dealership. Dealership mentioned there was recall and a software fix yet I never received a notification. Still waiting for control cable in steering column that was broken while maneuvering car back into parking spot.
