Luxury SUVs are overtaking the market, and customers couldn’t have been happier to get behind the wheel of a 2018 Audi Q3. The automaker claims that the newest lineup is “engineered to progress at your pace,” but research suggests otherwise. In fact, the faulty exterior lighting, defective electrical system and poorly-built structure all pose safety risks to occupants.

Problems with the Exterior Lighting

The various forms of exterior lighting are meant to work together to alert others on the road of the Q3’s presence on the road. When one aspect of this fails, it becomes dangerous to drive the SUV, yet we see many unsuspecting drivers facing this problem. Often, modern vehicles alert occupants when there is a problem with the turn signal, but that seems to be an issue with this Q3 model. Sadly, there aren’t a lot of documented complaints about the situation, because customers don’t know it’s happening. This ignorance leaves people in a lot of risk, especially while making a turn.

To correct the situation, Audi issued a recall of Q3 SUVs. NHTSA Campaign Number 19V385000 states that the indicator for a failed turn signal isn’t working correctly. Without this indicator, others on the road aren’t aware of the upcoming turn, which could lead to an accident. To repair the situation, owners must have the body control module replaced. In the meantime, drivers everywhere are making turns without the proper signaling equipment, thereby putting their luxury car and occupants at risk. Maybe this vehicle was “engineered to progress” in a straight line only.

Problems with the Electrical System

As with the lighting situation, there are other electrical system issues plaguing this Audi model. You can find several people discussing the defective backup camera situation.

One NHTSA complaint says, “Backup camera won’t work when car transmission is in reverse, nor when manually pressing Park Assist button. This has happened on a couple of occasions before, but I thought it was a fluke. Today backup camera was completely disabled multiple times while driving when putting transmission in reverse.”

Audi isn’t afraid to discuss electrical system issues. In fact, the company currently has more than 30 service bulletins related to electrical malfunctions and problems. Service Bulletin #A801809 2050693 even talks about a strange whining noise that comes from the instrument panel. So, what this Q3 offers is a malfunctioning turn signal combined with the lack of backup camera while attempting to go backward. On top of that, owners get to listen to an annoying sound coming from the instrument panel at the same time, as a reminder of how this Audi SUV is a lemon. Overall, it’s not what a luxury car owner wants, but also a rolling hazard that should be avoided at all costs. Other drivers that see one coming should stay clear because there’s no way of knowing where this SUV is “engineered to progress” to.

Problems with the Shattering Sunroof

It isn’t cheap to drive a 2018 Audi Q3. Owners spend a good chunk of change to drive this luxury model and expect it to be made from high-quality materials, but that’s not the case. In fact, one NHTSA review states, “Driving during the morning on my way to work I heard this explosion and a sound behind. When I pulled off I noticed my moonroof was shattered. Just about to fall off or blow away. No object had hit the car. It was simply a huge explosion.”

Unfortunately, this is not a random complaint, but something found by numerous owners, yet no recall has been issued. The only thing the company has been willing to acknowledge are some squeaks and rattles coming from the roof area with panoramic sunroofs. This is illustrated in Service Bulletin #A701866 2038029, and shows that the structure wasn’t built correctly. If it was, owners wouldn’t need to deal with unnecessary noises or shattering auto glass. This SUV is engineered for something, but it’s not progress. Instead, it’s safe to say this vehicle belongs in the junkyard.

The steering wheel started to make a weird noise while turning the airbag light then came on the steering wheel buttons stopped working. Took the car to dealer and the clock spring was defective non working. This is a safety issue I paid 821. 57 to fix this issue out of pocket. My car only has 50 k in mileage and the airbag would have not deployed if I was in an accident. This sounds like a safety issue needing a recall for this vehicle

Panoramic sunroof exploded today while driving at highway speeds. Broken glass gave way. Car was not struck by any objects before the glass failed. There were no warnings. Have not yet taken the car to a dealer or service provider. Though it did not happen to me, there's danger from the explosion itself and from the glass entering the cabin.

Noticed a clicking sound in the steering column that was intermittent; after a week, the airbag light lit up and stayed lit ... Per the manual, contacted audi immediately for service. Was told it was a "clock spring module" and that it would take a few weeks for the part to come in. I was also told that the airbag would likely not activate in a crash ... They could not guarantee it would also not automatically just deploy. It has now been over 2 months and the service department at audi has told me that they have no idea when that part will be available. Additionally, none of the other buttons on the steering column are active now.

This particular model of audi q3 has poor quality break pads and rotors, if you live near the ocean like me in miami beach, the breakes get damaged at only 8,000 miles intervals and they can fail causing an accident. I reported the issue to dealer and manufacturer, and they have fully washed their hands. They are aware of the issue, and have not issued a recall. I am in the process of retaining class action counsel to pursue class action litigation.

Tl* the contact owns a 2018 audi q3. The contact stated that there was a failure with the dimension of the tires pertaining to a caster diagnosis. The color green displayed if the tires were balanced and aligned correctly when installed. The contact stated that the tire inspection caster testing remained in the red within less than 100 miles of owning the vehicle. Three different dealers were contacted: audi north austin (12971 pond springs rd, austin, tx 78729, (844) 473-2985) audi dominion (21105 I-10, san antonio, tx 78257, 1-(888) 478-2089), and audi north park (15670 I-35, selma, tx 78154, (210) 960-6000). The dealers serviced the vehicle, but failed to provide a permanent solution. The vehicle was unable to be driven safely due to several alignments, tire servicing, and tire replacements. Two different independent tire technicians provided further diagnostic testing and determined that the caster was not available from the manufacturer as proprietary information. The approximate failure mileage was 100. *bf *tr

I was driving on the freeway at dusk at 50mph when the sunroof in my q3 spontaneously exploded into a million pieces and rained glass down on me. I was unharmed and able to exit, but it could have caused a major accident as it was a tremendously loud and startling event. Audi determined that there was no projectile that caused the breakage and are replacing it as being "under warranty".
