For families that require three-rows of comfort, there aren’t a whole lot of options on the market. The 2019 Chevrolet Tahoe continues to be a popular option, since its first release in 1995. The company is quite proud of this model, even stating, “it’s the best for a reason.” On the other hand, research shows that there are plenty of reasons that it is one of the worst. The steering malfunctions, there are electrical issues and it comes equipped with a faulty powertrain.

Problems with the Air Bags

To protect the occupants in a vehicle, the air bags must be in working order. However, this Tahoe seems to struggle with the basics.

Here is one NHTSA review. “The contact stated they rented a 2020 Chevrolet Tahoe. The contact stated that while coming to a stop to make a U-turn, the steering wheel suddenly locked. The vehicle continued to accelerate forward crashing into a wall on a driveway of a home nearby. The vehicle’s air bags did not deploy. The vehicle was towed and had not been deemed totaled as of yet. A police report was filed. The contact received injuries to the head and knees. The contact stated there were 5 passengers in the vehicle, not including the contact, there was a passenger in the front and four in the rear. The contact stated the passenger in the front had head, mouth and wrist injuries. The passengers in the rear received injuries to their head, foot, ribs, legs, face.”

This is a serious situation that should be addressed, but even more importantly is the risk of fire this SUV possesses. NHTSA Campaign Number 19V837000 says that vehicles might not have a pressure regulator included in the fuel pump. If this occurs, the fuel pump could become over-pressurized and crack, which leads to a fuel leak. When gasoline is leaking out of the car, there is a higher chance of a car fire. Whether the Tahoe is attempting to crash people into walls with defective air bags or it wants to burst into fire, none of these situations constitutes being deemed “the best.” The only thing it is the best at is failing.

Problems with the Brakes

Speaking of failing, the brakes on the Tahoe are just as defective. Without functioning brakes, there is another chance of causing an accident and injury.

Just look at this NHTSA complaint. “My new 2020 Tahoe has auto/power pedal height adjustment. It allows both pedals in unison to be lowered or raised for comfort and dexterity of use. The height distance between the brake and gas pedal is extreme. There is an inherent danger of hitting the side of the brake pedal prior to getting one’s shoe onto the brake pedal. Women wearing sandals or open face footwear can possibly snag their footwear to the side of the pedal platform. Any heavy working type shoe is also prone to hitting the side of the pedal first. My wife and I both noticed this during our separate test drives. In each case, the timing of actually engaging the brake pedal endangers the driver’s ability to slow or stop his vehicle. Accidents will occur. I asked the salesman if the pedals could be separately adjusted, to which he stated it wasn’t possible. The inability to adjust either pedal’s height independently for each driver’s dexterity of engagement is important. Would both automatic powered side view mirrors be effective if they were set to be adjusted in unison only? I’m not sure when automakers made the decision to negate the ability to adjust the distance of height independently of at least one of the pedals. This is our first vehicle purchase since our last in 1985. It appears to me that it has been an unapparent or unnoticed possible reason for accidents.”

Aside from this, there’s another issue causing unintended braking. NHTSA Campaign Number 19V761000 states that over 650,000 vehicles have a serious software malfunction. If the wheel speed sensor fails, the Electronic-Brake Control Module (EBCM) software could activate the driveline-protection system. This defect causes the brakes to apply on the opposite wheel, which pulls the vehicle to one side. Not only can this lead to an accident, but if the air bags aren’t working either, occupants are put in a lot of danger. This only proves it is in fact the “best” – at putting people at risk of peril.

Problems with the Electrical System

One final aspect that needs to work well with a family vehicle is the steering system. Yet, this is just one more area for the Tahoe to fail.

Here is one KBB review. “The magnetic ride is harsh vibrations in the steering wheel and seat. Returned the vehicle with 81 miles to the dealership did road force balance no change. Told by service that is the way it is. Have owned Tahoe and Yukon in the past. Asked the dealership to buy the vehicle back no response. Very disappointed! Trading for Ford Expedition. If you are considering buy any GM vehicle with Magnetic ride control do an extended test drive!”

While this customer talks about the harsh ride, there is more to focus on here. In fact, the company claims that even the basic details of the steering system have been overlooked. With Service Bulletin #16NA109, Chevy tells technicians to inspect the steering gear for excessive grease or sealant. True auto technicians shouldn’t be dealing with this problem in the first place, as there’s no reason to have excessive amounts of grease on parts. From small to large, everything seems to be an issue with the Tahoe – making it the “best” lemon.

Description
My engine light keeps coming on randomly. When this occurs, the dashboard lights blinks and I get a " steering assist" error message. Once this happens it is really hard for me to steer and I lose acceleration as well. Imagine losing acceleration in the middle of an intersection. Also, I noticed my temperature gauge moves up & down as well. I have taken it to the dealership each time it happens and they are saying they haven't been able to replicate the issue. The engine light only stays on for a few hours or days and the problem goes away once the engine light is off. From my research, this was the same exact problems the 2015 chevy tahoes had as well. I don't understand why they cannot figure why I am having this issue. The engine light errors code listed alot of issues yet they still can't diagnose a problem. They have updated the system and checked all wire connections per the dealership. This is my third or fourth time complaining about this issue and this is the dealership's third or fourth time trying to diagnose the problem but they keep telling me they can't.

In august 2021 I got a system light for a saftey restraint system, aka airbag issue. This system was going on and off sometimes as little as 5 seconds apart and then sometimes would go off for a bit then back on. I live on an island and there is no dealer here I had to buy somewhere else. There is a mechanic here that does work on vehicles and per the dealership, I bought the car from I was told if the mechanic there can do a software update which is what he thought the problem was, then I should do that. I took this advice and did it. When we drove off the light was off and fixed for about 30 minutes, then the light and safety restrain error came back on. This time remaining on. I took it back to the mechanic and got two error codes. I have since tried to contact gm and been dealing with them for 3 weeks with no assurances if I pay to get my car to a dealship to fix I would get my money back for their error. I also came across and article about investigations into 750k 2020 & 2021 gm models including 2020 chevy tahoe for airbags not working. As a consumer, I should have the right to be able to be reimbursed for costs accruded to me to get my vehicle where I'm forced to get it fixed.
