Chevrolet Bolt Investigated For Battery Fires

Posted on by

The National Highway Traffic Safety Administration (NHTSA) have opened an investigation into certain 2017-2020 Chevrolet Bolt electric cars after several complaints of vehicle fires. The NHTSA says it was contacted by two owners who reported that their Bolt EVs caught fire while parked and unattended. In one case the vehicle was plugged into a charger in the owner’s driveway when it caught fire. The second vehicle was parked but not plugged in approximately 20 minutes after being driven, before it caught fire. Additional research by the Office of Defects Investigation (ODI) found a third vehicle, a 2017 Bolt EV with a similar burn patterns.

In all three cases, fire damage appeared to come from the battery compartment with fire passing into the passenger compartment from under the rear seat. The root cause of the fires is unknown and the ODI is opening a “preliminary evaluation” into the matter. If the investigation results in a vehicle recall, approximately 78,000 Chevy Bolt EVs would be affected.

Posted on by

General Motors will be contacting the owners of certain 2020-2021 Buick Encore GX , 2020 Cadillac CT4, CT5 and XT4, 2020 Chevrolet Corvette and 2021 Chevrolet Trailblazer vehicles because of a problem affecting the electronic brake boost system.

According to the defect report, a connector in the system may have become contaminated during the manufacturing process. The contamination could interrupt the communication between the sensor and the system, under certain conditions. If communication is interrupted, electronic brake assist could be lost and the driver will require extra pedal force to stop the vehicle. Drivers may also notice an illuminated brake warning light in the instrument panel and the vehicle speed may be limited.

Owners receiving notices will be asked to return to their dealers to have the electronic brake boost module replaced. GM’s number for this recall is A202307260 and the NHTSA campaign number is 20V-588.

GM Infotainment Problems

Posted on by

A class action lawsuit has been filed against General Motors for problems affecting its IOR 7 inch infotainment system installed in certain 2019-2020 Chevrolet and GMC vehicles. The lawsuit alleges that GM’s infotainment system problems are a dangerous threat to drivers and passengers.

According to vehicle owners, GM dealers refuse to replace or repair the faulty infotainment systems. The automaker has not released a recall, although they have issued a technical service bulletin acknowledging there is a problem. (NHTSA-TSB-PIT572)

The class-action lawsuit claim that certain GM vehicles with IOR 7 inch infotainment systems are prone to experiencing a range of different issues. Some owners say that the ringer never shuts off with incoming Bluetooth calls and the vehicle operator must turn off the ignition, open and close the vehicle door, and restart the ignition to stop it. Some say the rear view camera’s display image will stay on for up to one minute after shifting out of reverse. The biggest complaint reported involves the the system’s audio volume which will suddenly spike to max volume, distracting drivers while they are behind the wheel.

GM Trucks Brake Pedal Vibration

Posted on by

General Motors has identified a defect which could affect vehicle safety in certain 2018 Cadillac Escalade, Chevrolet Silverado 1500, Chevrolet Tahoe, GMC Sierra 1500 and GMC Yukon vehicles equipped with 5.3L or 6.2L V8 engines. They will be asking owners to return to their dealerships to have the Electronic Brake Control Module reprogrammed.

According to the defect report, these vehicles may have a condition in which the engine mounted vacuum pump output could decrease over time. If the vacuum level drops, drivers may notice a vibration in the brake pedal, increased braking effort, a hard brake pedal and/or increased stopping distances. The drivers information center “Service Brakes” warning light will illuminate and a diagnostic code will be set. The condition is most prevalent at low speed and soft braking.

Dealers will correct the problem by reprogramming the electronic brake control module to improve how the system uses the hydraulic brake boost assist function when the vacuum assist is depleted. GM’s number for this recall is N202300860 and the NHTSA campaign number is 20V-603.

Is Your Cadillac Escalade A Lemon?

Posted on by

The Escalade is a full-size luxury SUV engineered and manufactured by Cadillac. It was Cadillac’s first major entry into the luxury SUV market in response to competition from Mercedes-Benz, Lexus and Ford. Today, Cadillac makes their Escalade in an EXT, ESV and a hybrid version as well.

The 2015-2016 Cadillac Escalade models have received some of the highest complaints and recalls of all the model years. Although there have been no recalls for transmission problems, complaints are common. Drivers say there is a “distinct clunking and surging when accelerating and decelerating, and the transmission becomes stuck in gear.” The 2015 Cadillac models have 167 manufacturer communications / TSB’s affecting the power train, many which recommend flushing and changing the transmission fluid. The problem is a common complaint with many 2015-2019 Cadillac, Chevrolet and GMC owners and is part of an ongoing class action lawsuit between vehicle owners and GM.

Drivers of certain 2015-2020 Cadillac Escalade vehicles believe that shaking and vibrations are caused by the same transmission defect, but some attorneys say the symptoms are caused by a defective drive shaft. The problem has been so wide spread, it has been coined “The Chevy Shake”. A few owners say they fixed the problem by replacing the aluminum drive shaft with a custom steel drive shaft, but GM continues to replace parts with the same defective parts.

Electrical defects are common in many newer Cadillac Escalade models. Heating and air conditioning are the top, with exterior lighting and software problems following close behind. Other complaints include: thermostat gives wrong information or just doesn’t work, no control of audio, Bluetooth intermittently disconnects, complete failure of the instrument cluster, repeated electrical shorts and temporary loss of the electric power steering.
