2018 Volkswagen Atlas: grinding or squealing brakes

Filed Sep 8, 2025 · Engine · WI

Our 2018 VW, when extremely hot temperatures would make a very loud grinding/squealing sound. Then the AC would intermittently work, sometimes it would blow cold, and sometimes it would not. Eventually, the AC stopped working altogether. There is a strong, hot, burning smell that comes through the vents during these times. These issues have caused extreme visibility as my windows fog up in humid conditions, causing me to not be able to see. I was almost in a car accident from this due to not being able to see and being in a large amount of traffic, trying to pull over to the side. This happened probably because the AC also dehumidifies the air for defogging. We had our VW into the Morris dealership, being sent home each time, stating nothing was wrong. The last time we had it in demanding something was not right. They stated the AC Compressor is not engaging now. Well, this explains why, every time it is hot and humid or raining, my windows are fogging up, causing me to not be able to see anything. This is an extreme safety hazard and has been for me and my children. This also explains the musty smell because this can cause mold and bacteria to grow due to trapped moisture. This is hard when this is our only family car, and many safety hazards.

When braking normally, the AEB alert tone sounded, and the display showed a red BRAKE warning with "Brake Booster Failure" displayed on-screen. The brakes then became extremely sensitive and caused the car to abruptly grind to a stop with full ABS action. This occurred in traffic, and the car behind me narrowly avoided a collision due to the uncommanded abrupt halt. I pulled over and the error cleared itself after a few seconds. I pulled the diagnostic error codes from the ECU, and this is the output: 0213 [0x0000D5] Archive (inactive) C10A329: Vacuum sensor, Implausible signal Single Vacuum Pressure Sensor sends no valid data Status bits: 1 Priority: 1 Frequency: 1 Unlearning index: 84 Odometer: 27031 km Date, time: 2023.03.27 09:34:50 Paramteric values: 00 00 80 18 32 00 00 00 CF 47 00 00 02 FF 00 5E 02 40 B0 00 00 00 10 Status: Confirmed (This is from a previous activation, but the recent one is the same). This is the third time this has happened, but the first to put me in actual danger of a crash. I have previously brought this to the dealer but no fix was applied. They were aware of this happening on other vehicles but they did not have a fix. The model year after was recalled due to wiring issues, but my car has never been recalled for anything related. I believe this is a significant safety issue and should be addressed by the manufacturer before it causes a serious incident.

Front steering knuckles fractured on the vehicle while driving, causing me to lose control of the vehicle. Other Volkswagen Atlas' have been recalled for this same issue, but not my specific model. If this is a problem for similar vehicles, people will be at risk of serious injury or death if not fixed immediately. I currently am on a military assignment in Germany and am having difficulty working with the dealers here to confirm the issue. Luckily I was in a parking lot when my steering knuckles failed and was able to park the vehicle safely. There were no warning indicators on the vehicle before I lost control. The vehicle did have a few symptoms of failing steering knuckles, like grinding and shaking sounds.

My car recently started feeling like my tires or rubbing on something when I make sharp turns. Now when I brake my car feels and sounds like it is grinding on something. It started happening while on way home from a trip a couple of days ago. While I wait for service appt the car is unsafe to drive as I need to really push on brake to ensure complete stop, it feels like the car is rubbing on metal and is very bumpy when coming to stop. Have only driven in slow speeds since returning home bc we are afraid the brakes will fail.

While applying brakes to come to a stop at a stop light, the brakes would not work and then made a metal grinding sound. An alert went off and the brake light began blinking. The automatic brakes engaged and slammed on. The brake light went solid and then off, and was replaced by a "brake booster faulty" warning. After this incident, the vehicle returned to normal functioning.

When riding in the passenger seat the air bag would disengage and engage as the person moved in the seat with the movement of the car. Moved the seat back and it went off, dealership mechanic could find nothing wrong. Last happened this morning, started after a few seconds of grinding, then went 12 MPH, shut down, then started fine. Had the vehicle for 14 months the battery went dead, when pushing the start button it would catch and continue to try starting even when the finger was removed. When it started epc would come up and the vehicle would move at about 12 MPH. Shut the vehicle down and start again, it would run ok. Have had it into repairs twice and nothing is found, yet it continues to start or not start and run slow. Warning comes up check running light, check right headlight, check left headlight. Replaced the battery two months ago, have already had to charge because it has gone dead. It is like the computer panel is not turning off. The vehicle has always been stopped - parked when it will not start, sometimes for a few minutes some times over night after having to use the fog lights. I have all the recalls fixed, but this started after having those fixed. My battery was replaced after 45,000 miles.

Takata, oil was low upon purchase, had to replace oil within the first 100 miles and second time at 5,000 miles along with the coolant! Coolant was completely gone at 5000 miles. Air vents are horrible- smell of oil/coolant seeping into the vents when the vehicle is on. Outdoor smells come into the car along with exhaust from other cars. Shifter jumps and is stiff while going out of park to neutral, from park to drive etc. Very toxic this vehicle is, not safe when idling...when in neutral the vehicle as I would be in a drive thru perse and then brake to go from neutral to drive, the trans will "jump" grind into gear!
