What is the recall on the 2017 Cadillac CT6 transmission?

The 2017 Cadillac CT6 falls right in the middle of the 2016 to 2019 range of CT6 models in the General Motors class action lawsuit for GM 8L45 and 8L90 automatic transmissions. The lawsuit states that CT6 models might exhibit jerky, improper operation. No recall is active for the CT6’s transmission.   

As a result of the transmission issues and other problems, Consumer Reports put the 2017 CT6 on its list of “Used Cars to Avoid Buying.” Specifically, CR’s Annual Auto Survey says the model has “worse-than-average” reliability and recommends “skipping” it along with the other models on the list. 

What problems does the 2009 Cadillac CTS have?

The 2009 Cadillac CTS has 59 complaints with the NHTSA for engine problems and 25 for electrical issues. The model’s most common issue is timing chain failure, which could happen at an average mileage of 95,050. Unfortunately, the typical repair cost is around $3,400. 

Regarding electrical problems, owners of the Cadillac model report gremlins like randomly locking doors, faulty airbag lights, and ignition issues, per Car Complaints

The 2015 Cadillac Escalade’s most common problem is transmission-related. Specifically, the 2015 model is the first year named in the transmission class action lawsuit. As a result, 2015 Escalade owners report improper operation, including jerkiness, abrupt shifts, and shuddering. 

Does the Cadillac SRX have transmission problems?

The 2010 Cadillac SRX has very few owner complaints of transmission problems. However, a recall naming the Cadillac SUV model cites improperly installed shift cables that could cause improper operation or transmission failure.

How many miles will a 2015 Cadillac ATS last?

A 2015 Cadillac ATS could last over 200,000 miles with proper care and maintenance. Consult your owner’s manual for your model’s service intervals.

However, a handful of issues could frustrate owners. For instance, owners complained about the interior quality, including faulty infotainment screens and trim cracking.
