2019 Audi Q5 Complaints

2019 Audi Q5 had the hardware fail which controls the rear view camera (controls other functions too) It's known as the MMI and the replaced part says "MIB2 Main-Unit" on the housing. I have the old part that the dealer replaced in my possession. Dealer confirmed the part was broken and would require replacement. not having a rear camera impacts safety in parking lots, backing in to streets etc, as well as increased risk of backing off the road esp in tight settings. there was no initial warning - it 100% stopped working then would give some warnings or random short term use the past 3 months while scheduling replacement. Completely unreliable for day to day safety, as we back on to a busy road multiple times per day.

Went to Mavis on Weber Rd in Bolingbrook, IL for front brake replacement on June 6, 2026. It took 6.5 hours when I was originally told when I called to schedule the appointment it would only take 1.5 hours, so it was obvious that something was wrong. Within 100 yards of leaving their parking lot after the service appointment, an obvious clattering was present. I immediately called them to let them know the replacement had not been performed correctly. Booked appointment with Audi of Naperville first thing Monday morning to have them fix whatever was wrong - the earliest appointment I could get was June 11. Drove the car until Wednesday evening when something went very wrong and constant clatter was replaced by loud scraping and brake lockup when I exited 355 on my way home from work. Called someone that night to have it towed to Audi for the next day's service appointment. Audi videoed their inspection and shared the video. Their inspection revealed one caliper entirely missing from th...

2019 Audi q5 drive system malfunction/start stop malfunction. Error code will come on randomly in traffic and when you try to put your foot on the gas it hesitates and you need to push harder on the gas. Car will also lose acceleration power and take longer to reach desired speed. Drive system malfunction light will come on as well as an error stating start/stop system malfunction. Have had multiple sensors and battery replaced with only temporary results. Start stop malfunction will come on randomly at any time and then go away for a certain amount of time and come back again. This malfunction is constantly going on and off and is sometimes dangerous because you don’t know when it will happen, if it does happen you don’t know if you need to press harder on the gas, or if you do accelerate you don’t know if you’re damaging your engine. After multiple fixes at Audi dealership and other repair shops, them attempting to address this issue has done nothing for the car leaving me to believe...

My seat belt warning has been going off intermittently. I received an extended warranty from Audi Subject: Seat Occupancy Detection System Limited Warranty Extension extending the warranty for my car. However, when I took it to the dealer they could not replicate the sound. I provided them a video of it happening. They said it was not showing as a fault on the computer and therefore refused to repair the seat under the warranty extension. This is a safety issue and it's recognized as one by Audi. This sensor is obviously malfunctioning for a lot of people or they would not have extended the warranty. Regardless of being able to "replicate" the issue, they should replace the sensor since it's a known issue and they extended the warranty on it.
