General Motors has issued a service update for some examples of the 2020 Cadillac CT5 luxury sedan over an issue relating to the upper intermediate steering shaft.
The problem: affected vehicles may have a condition where the upper intermediate steering shaft contacts the front brake line.
The hazards: GM has not specified what hazards may result from this problem, but it is clearly suboptimal to have anything contacting brake lines. In the worst cases, friction can cause the line to fracture, leading to an immediate loss of brake fluid and a consequent reduction in the car’s braking ability. There is no suggestion in the service update that this will happen to affected CT5s.
The fix: dealers will inspect the brake line in question and, if necessary, replace it. Cadillac dealers will also be required to replace a number of adjacent parts including front lower control arm bolts, air-conditioning seals and, on all-wheel-drive models, catalytic convertor gaskets, an engine mount bolt and a front drive shaft nut, among other items.
Affected component: front brake line.
Affected vehicle: 2020 Cadillac CT5.
Next steps: dealers will check all Cadillac CT5 vehicles in their inventories, and customer vehicles which return to the dealership for any reason. The bulletin will expire at the end of the involved vehicle’s New Vehicle Limited Warranty period.
- General Motors recall number: N202296840
- Cadillac U.S. vehicle help number: 1-800-333-4223 (8 am to 9 pm EST every day except Sundays)
This service update comes less than two months after the Cadillac CT5, among other GM vehicles, was issued a technical service bulletin (TSB) to address a potential water pump failure issue. In September, the CT5 was also issued a stop-sale notice over a problem related to the electronic brake boost system which also affected other GM models.
More positively, J.D. Power named the CT5 as the top luxury model in the Convenience Tech category of its 2020 U.S. Tech Experience Index.
