2016 Volvo XC90 Electrical System Problems

The hybrid motor periodical will hesitate when accelerating from a stop, specifically it'll start accelerating then lose power for up to a couple of seconds before regaining power. This poses a safety risk if you start pulling out into traffic and suddenly and unpredictably lose power while there's oncoming vehicles. The problem just occurred for the first time about a week ago and coincidentally just a few days after taking the car in for its annual service, since then it has happened more frequently and I can't find any rhyme or reason as to why it happens. The vehicle will be going in to be checked out shortly. There have been no warning lights any time this has happened.

The contact owns a 2016 Volvo XC90. The contact stated that water had been leaking into the vehicle on rainy days. The contact stated that the water intrusion was causing several warning lights to illuminate and unknown vehicle safety equipment failures. The contact stated that the front and rear carpets and the spare tire were saturated with water. The contact had taken the vehicle to a local dealer, where it was determined that water was leaking into the vehicle, but the dealer was unable to determine the point of intrusion. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 168,000.

The car has a factory fault with the Windshield Wiper or Turn Signal contact switch, which is causing the inability to use the left/right signal and the wipers. The entire part is factory faulty, rendering the vehicle unable to operate safely. This affects visibility during wet conditions because the wipers cannot be activated due to the malfunctioning switch, which can lead to serious accidents. Additionally, malfunctioning left/right turning signals can also cause serious accidents, as it is a crucial function. Yes, the vehicle is available upon request. I contacted Volvo, but they declined to fix the issue. They have published a technical bulletin regarding the problem but are not recalling the vehicles. Many other Volvo models have the same factory defect, as can be found on the internet. The technical bulletin confirms their fault. I have attached the file. No, the vehicle has not been inspected. Yes, the vehicle shows a "turn indicator malfunction" message on the main screen. This issue started around 89k miles.

When driving and stop in a traffic light, for example, the Volvo ignition going off and I have to re-start it. The problem is rooted probably in the fuse associated with Volvo's stop/start motor. I found that other models have had the same problem, like the recall#R39574 and the reference safety campaign #15V555000.If the fuse blows in traffic, it could increase the risk of an accident, especially a rear-end collision.

The DIM (driver/driving instrument module), also known as the dashboard, on my vehicle suddenly stopped showing anything (speed, gas or battery charge level, etc.) recently, although there is still power (I could see the background lighting in the dark) and the vehicle can still be driven. This is certainly a severe safety issue. I had my vehicle checked at a Volvo Dealership shop; their diagnosis concluded that the entire DIM needs to be replaced; software update alone won't solve the issue. I shared this issue at a social media site (Volvo XC90 Owners Club at Facebook) and several others said to have had the same or similar issues with the DIM. I'd suggest Volvo to recall this safety issue.

On a travel trip to Seattle, we stopped at few stop, and when my sons tried to exit the rear doors, both would not open. Neither from the inside or outside. Nothing worked. Upon searching, this is a very common issue with the 2016+ models. When inquiring with volvo, it will cost anywhere from 1000-2000 per door to fix the "locking" mechanism which they say can corrode. Ridiculous. This is a major safety issue if passengers can't exit. I've never had a car which a door can't be opened.

The contact owns a 2016 Volvo XC90. The contact stated that the vehicle had experienced high oil consumption. After adding oil to the engine, the message "Oil Level Low" was display within three weeks. Additionally, while operating the vehicle the message "low engine function" had displayed and the vehicle would not properly accelerate and was jerking. The contact also discovered puddles of water inside the rear trunk of the vehicle with electrical wires and components submerged in the water. The vehicle had experienced various electrical failures with the back-up camera malfunctioning. In addition, there was mold inside the vehicle. The cause of the failure was not yet determined. The manufacturer and local dealer were contacted regarding the failures. The failure mileage was 75,000. The VIN was not included.

It came to my attention this summer that my 2016 Volvo XC90 has an extensive sunroof drainage problem that has resulted in major leaks in the interior of the car and that has destroyed the electrical system which impacts everything (airbags, speed control, back up camera, object alert warnings, etc. It was impossible to have knowledge of this problem until it was too late (like cancer). Many dashboard lights came on, the car was acting funning, back-up camera did not work, AC worked intermittently, standing water in trunk, headliner water damage, etc. Onboard diagnostic system also not working. I have attached the preliminary report but dealership saying they need to pull up carpets, seats and dash to get to a full diagnosis. Here's summary I put together(Volvo Corp won't really communicate w/consumer). I have photos if needed: I also spent time the last several days continuing to do my research. It takes little more than a google search to understand the widespread sunroom drainage/leak issue with many Volvos. There are too many articles to list, but here is one: [XXX] recalls 127K vehicles due to leak The recall covers 2016 and 2017 XC90 SUVs and S90 sedans Myriad Facebook complaints I also spoke to service managers at various other Volvo dealerships. They have seen and continue to see this sunroof drainage problem and according to them, it is not minor nor unique. They agreed that the first incomplete estimate (~$3,500) that dealership is just that: incomplete. They said there is no way to know extent of the damage until carpets, dash, etc., are removed to see what full damage is but that they often see the need for full body harness replacement. It is special order + requires time to get and considerable labor hours to replace. That can push estimate up to $8,000-$9,000, well above estimate thus far from dealer. And the car will never be the same. Undriveable now. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The indicators do not work randomly and we have had near miss accidents. The bulbs are in good working order. The stalk functions correctly. The computer after several seconds flashes up a message that the system has failed. Clearly the system is not safe as it’s designed. If Volvo are using a computer system to operate the lights it should be sufficiently reliable and fault tolerant to maintain safe operation of the vehicle.

My vehicle’s SOS, On Call safety functions no longer work. In addition my navigation system no longer works properly. In the event of an accident These key safety features would not be able to alert emergency services or locate my position. This is a direct result in a flawed vehicle modem that uses the 3G network not supported by cellular carriers. Volvo has a solution that would cost me $850 to remedy this safety design flaw. Volvo should fix this key safety issue as it puts my family at risk if we are involved in an accident

Main Cooling system hose burst while driving down the road. Volvo Dealer said extremely rare for this to occur. Car overheated, all warning lights appeared and coolant exploded under hood all while driving.Had to have repaired $1000. Also a water leak inside 3rd row & leaks from rear view mirror area. Caused electrical damage to main system computer module, had to have replaced $2000+. All work done at volvo dealer. No frame damage,no missing parts, dealer stated unknown reason. Same thing is now happening a 2nd time and warranty will not cover water damage. Have spoken with others experiencing the same problem with roof leak. No alarms came on prior to combustion/main hose top engine area before break. Happend immediately, unexpectedly

First, the rear passenger side door latch failed at 57k miles, allegedly due to water intrusion. They replaced with a revised part - p/n 32310869. Now at 63k miles, the driver side rear door latch failed in the same way. This compromises safety because it renders the rear seats completely inaccessible. I could not get my children out of the back seat through traditional means. The problem has been confirmed by a dealership and is well documented online. There was no warning or indication when the part had failed. The passenger door stopped working "regularly" (intermittently would not open) a few days before it failed entirely. The driver rear door gave no advanced notice.

The attached file outlines details - 1.After a recent car wash at a Shell Service Station…..April 5,2021, upon starting the vehicle – the computerized dashboard displayed erratic and incomplete information. It attempted to indicate multiple system failures – eg brakes, suspension, and others too garbled to understand. The entire driver’s console and information center display which were designed to show all of the vehicle operating modes and driver information were compromised and not functioning correctly. The Start/Stop Switch would no longer shut the engine down. I could not get the vehicle to shift out of Park. I found myself quite concerned about a highly computerized vehicle now running with no apparent operator control. I could not be certain whether the engine was being cooled properly from its electrical fans because the cabin was becoming uncomfortably hot. None of the environmental controls worked. Even the electric windows were affected. There were no engine safety indicators of any kind visible working to ensure electrical, engine oil pressure, coolant temperature….none of the other operator information systems were working properly and the engine still could not be shut down. I found myself uncomfortable getting out of the vehicle since it has so many self-driving, collision avoidance steering and braking functions that could be affected. I did not want to risk being run over by my own car. Nor, could I allow the vehicle to move, possibly on its own…so I sat in it for about 3 hours sweating while waiting for a Volvo Tow Service to arrive. The Tow operator was somehow able to get the gear shift to move and was able to back the vehicle out to the street and onto his truck. He was also unable to shut the engine down and towed it to the Neillo Volvo Dealership about 3.5 miles away, here in Sacramento CA. I had deep concerns about safety with this vehicle being towed with the engine still running. All of the instrumentation remained unusable. The consumer stated after the sunroof clogged d
