The engine is arguably one of the most important parts of any vehicle. When it comes to driving a luxury model, it’s natural to anticipate plenty of power and reliability, but that’s not what the 2019 Audi Q8 offers. Instead, there are some major motor issues that must be addressed.
Just look at this NHTSA complaint. “There is a noticeable throttle lag (hesitation) when the auto start/stop feature is enabled, and the car comes out of a rolling stop (ex. When making a left turn). Disabling the auto start/stop feature or selecting Sport mode negates the issue.”
The auto start/stop system shuts down the engine and restarts it automatically to reduce how long it spends idling. This reduces fuel consumption and lessens emissions, which is a major reason that owners want to drive a car with this feature. Disabling it defeats the purpose of having this innovative technology on-board. Still, it appears there are many engine issues that Audi doesn’t know how to fix. Service Bulletin #A0119232054182_2 talks about how the engine can misfire. Instead of offering a fix, Audi states for technicians to “explain to the customer that a solution is forthcoming and currently scheduled for the late 4th quarter of 2019. No repairs are necessary at this point.” Instead, the luxury car company expects drivers to continue operating their overpriced SUV with a misfiring engine. Maybe it’s time to lower expectations.
EXCESSIVE AND DANGEROUS DELAY IN THROTTLE RESPONSE DUE TO AUTO START/STOP SYSTEM CAUSING VEHICLE TO COAST WHEN SLOWING DOWN AT A YIELD SIGN OR INTERSECTION ETC BEFORE TRANSMISSION RE-ENGAGES. THE VEHICLE IS POWERLESS FOR SEVERAL SECONDS DESPITE APPLICATION OF GAS PEDAL, CAUSING ONCOMING TRAFFIC TO POTENTIAL COLLIDE WITH “STALLED” Q8. THIS IS A MAJOR DESIGN DEFECT IN THE AUTO START/STOP SYSTEM AND OCCURS EVERY TIME THE SYSTEM IS ACTIVE.
As we evaluate the various transmission issues, we see the same rough ride illustrated earlier.
On the NHTSA website, another driver wrote, “On multiple occasions, Q8 will not accelerate when gas pedal applied for roughly 1-3 seconds when coasting to a stop or immediately coming out of a stop, causing the vehicle to remain stationary although gas pedal is applied. Once the vehicle responds to the depressed accelerator, after a delay, then the auto can accelerate beyond the requested acceleration. It feels like the vehicle is trying to decide whether or not to respond to the depressed accelerator, leaving the vehicle vulnerable if trying to cross traffic, accelerate from a stop sign, or turn left between oncoming traffic. The problem feels intermittent although feels like it’s becoming more common. Vehicle responds this way whether or not the auto stop feature is engaged or not.”
The issues don’t seem to be related to the auto start/stop feature. While there are nearly 200 service bulletins, the luxury automaker decided not to discuss one powertrain problem. Maybe they expect everyone to believe that there are no troubles present. It’s just another way to help owners lower their expectations while Audi does nothing to fix the issues.
THERE IS A SIGNIFICANT LAG IN THE POWER TRAIN OF THE Q8 AFTER BREAKING TO A COASTING SPEED AND THEN ATTEMPTING TO ACCELERATE AGAIN. THE GAS PEDAL IS COMPLETELY UNRESPONSIVE FOR 3-4 SECONDS DURING THIS TIME. THIS POSES A MAJOR SAFETY HAZARD IN SITUATIONS WHERE YOU ARE COASTING WITH THE EXPECTATION TO CROSS ONCOMING TRAFFIC. I HAVE EXPERIENCED THE ISSUE IN COMFORT MODE. SIMPLY APPLY THE BREAK IN ORDER TO SLOW THE VEHICLE DOWN WITHOUT COMPLETELY STOPPING. WHEN YOU ATTEMPT TO ACCELERATE, THE GAS PEDAL DOES NOTHING. AFTER THE LAG PERIOD, THE VEHICLE BEGINS TO ACCELERATE. I HAVE NOT BEEN ABLE TO REPRODUCE THIS PROBLEM IF I COME TO A COMPLETE STOP AND THEN PROCEED. I RAISED THIS AS A CONCERN TO MY LOCAL AUDI DEALER BUT WAS ADVISED THAT THERE ARE NO SERVICE BULLETINS REGARDING THIS PROBLEM. MY SOFTWARE WAS UPDATED TO THE LATEST VERSION DURING A RECENT SERVICE APPOINTMENT, HOWEVER, THE PROBLEM PERSISTS.
DANGEROUS LAG/PAUSE IN THROTTLE RESPONSE WHEN ACCELERATION IS NEEDED. WHEN COMING TO A ROLLING OR ALMOST COMPLETE STOP, THE AUTO START/STOP SYSTEM IS ENABLED. IF I GO TO TURN/ACCELERATE THERE CAN BE SEVERAL SECONDS OF TIME LAG BETWEEN PRESSING ON THE ACCELERATOR AND ANY THROTTLE RESPONSE. IT IS DANGEROUS AT TIMES WHEN PULLING ONTO A STREET AND THE CAR WILL NOT RESPOND AFTER A FEW SECONDS. ADDITIONAL THROTTLE PRESSURE DOES NOT INDUCE A THROTTLE RESPONSE, AND SUDDENLY THE CAR WILL SURGE AHEAD. THIS IS NOT AN ISOLATED INCIDENT AND AND SEEMS RELATED TO TRANSMISSION PROGRAMMING WHEN THE AUTO STOP/START SYSTEM IS ENGAGED, WHICH IT IS BY DEFAULT. THE DEALER SAYS THE CAR IS WORKING AS DESIGNED. THIS IS DANGEROUS WHEN MAKING CROSS-TRAFFIC LEFT TURNS BECAUSE OF THE UNPREDICTABLE DELAY.
THERE CAN BE A PROFOUND LAG IN ACCELERATION AT CRITICAL TIMES. I CAN COME TO AN INTERSECTION AND SLOW. WHEN THE GAP IS SAFE TO TURN WITH TRAFFIC OR ACROSS TRAFFIC THE CAR WILL NOT PICK UP AND GO. IT WILL LAG AND NOT ACCELERATE. I WILL COAST INTO THE INTERSECTION AND I FEEL AS IF I COULD BE BROADSIDED. THE LAG IS ABOUT 3-4 SECONDS. NOTHING….JUST A DEAD ROLL. IT WILL PICK UP AND ACCELERATE AT 3-4 SECONDS. I FEEL THAT THE GAP I WAITED FOR WAS TYPICALLY SAFE FOR OTHER VEHICLES I HAVE DRIVEN. IT IS NOT TURBO LAG….I OWN PLENTY OF DIESELS. IT IS DANGEROUS. IT CAN’T BE PREDICTED. IT CANNOT BE PREDICTED. THIS NEEDS TO BE INVESTIGATED BY YOU. AUDI SAYS THAT THE PROBLEM DOES NOT EXIST. THEY ARE UNABLE TO REPLICATE. THEY STATE THE VEHICLE OPERATES AS DESIGNED. BUT IT KEEPS HAPPENING AND CANNOT BE PREDICTED.
