Common Problems with the 2018 Chevrolet Tahoe

Engine Issues:

“The contact owns a 2018 Chevrolet Tahoe. The contact stated while driving at various speeds, the vehicle stalled with the check engine warning light illuminated on the instrument panel. Recently, the contact had the vehicle towed to a dealer where they diagnosed the vehicle with engine failure. The contact was notified of the diagnosis and the dealer recommended that the engine be replaced. The manufacturer was notified of the failure and the contact was provided a case number. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was 22,949.”

“When accelerating it sounds like my vehicle is stuck in brake degrading or is making that distinguishing noise. My vehicle is in the shop for the second time to fix the same issue of park assist, side detection and front camera service. When expressing my concern for this problem of the sound the dealership said let's fix the service issues first as everything is electronic. I hope my vehicle is safe to drive.”

Electrical System Problems:

“Purchased brand new Chevy 2018 Tahoe in April 2019. Overall good car never had any issues until 02/08/23 as I was driving a got a service alert "Trailer Brake System", It was so random since we have not hauled anything for that to even become a problem. The next day 2/09/23 the car was not drivable it wouldn't turn on it kept giving me the same alert "Trailer Brake System". I called the dealership and they said it's a defect and have to take the Tahoe in for service since only they can find the defected harness and now I have to pay out of pocket for something that I did nothing wrong, something that is manufacture defect and completely unsafe to drive.”

“Entire vehicle loses electrical power. The vehicle does not shut off, however. Lights, dash, display etc. Possibly a grounding issue. Problem has not been looked at yet, but has occurred twice in the last week. No warning lights available. Occasional park assist failure occurs, may or may not be related.”

“Passenger window when rolled up it rolls down automatically. Button has to be held in the upward position for window to stay up. Has already been serviced by dealership.”

Steering Concerns:

“Power steering went out with kids in the car when vehicle only had 76000 miles. There was a special coverage for 2018 models that my vin was not a part of. Had it been this wouldn't have happened to my family. I was without a vehicle for over 2 weeks since dealership had to reach out to GM to find the part. Apparently, this is big issue for other models and years which explains the part shortage. A few months prior there was a service power steering on my dash, and I couldn't turn my steering wheel. Took it to dealership and they brushed it off as computer issue. Again, I feel if my vehicle was part of the special coverage, I wouldn't have experienced this issue or had to pay over $2000 to repair it.”

“The contact owns a 2018 Chevrolet Tahoe. The contact stated that while his wife was driving approximately 35-40 MPH, the power steering assist failed. The failure occurred on several occasions, which nearly caused a collision. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 120,000. The VIN was unavailable.”

“When stationary and turning on vehicle I had difficulty turning steering wheel. I received a notification that power assist was not active. This happened once before and I took to dealer. They claimed it was the battery and replaced. I see there have been prior recalls on Tahoe for steering assist issues.”

Brakes Problems:

“The contact owns a 2018 Chevrolet Tahoe. The contact stated that while parked on a slight incline and shifting into reverse, the vehicle started driving down the driveway with the brake pedal depressed. The contact stated that the vehicle drove approximately 15-feet in reverse. The contact stated once on a flat service, the vehicle suddenly stopped. During the failure, the message "driving assist" was displayed. The failure had occurred on another occasion. The cause of failure was not yet determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was approximately 54,000.”

“When applying the brakes the SUV will pull hard to the left or at times to the right. I get a screen message that reads " trailer brake system failure". The SUV has never trailed anything. Also don't know if these are tied together but I'm also experiencing a dragging battery during this time. When the trailer brake says failure goes away the battery issue goes away. I've done some research and have found a GM service call "N192261050" which seems to indicate the same issue/concern.”

“Over the last 6 months the brake pedal is hard to push after the truck sits over night. The vacuum bleeds out indicating a vacuum leak in the system. GM and the dealer said this model and year not covered under current recall.”

“The contact owns a 2018 Chevrolet Tahoe. The contact stated while driving 40 mph and making a left turn, the vehicle started hesitating. The steering wheel ceased. There was no warning light illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing all four tires to be replaced. The contact replaced all four original tires however, the failure persisted. The contact took the vehicle back to the local dealer, where it was diagnosed with needing an alignment. The contact stated that the wheels were aligned however, the vehicle but continued to experience the failure. The contact stated she had the vehicle serviced four times but continued to experience the failure. The contact also stated that the low brake fluid warning flashed off and on, even after adding brake fluid to the vehicle. The vehicle was not repaired but was pending repairs. The manufacturer had been informed of the failure. The failure mileage was approximately 40,000.”
