My 2019 Cadillac XT5 has repeatedly shuddered at highway speeds since shortly after purchase on July 25, 2026. It occurs around 61–62 mph while maintaining speed before accelerating. The cause is UNKNOWN. The selling dealership evaluated the vehicle and performed a front-wheel alignment, but the shuddering persists. Its repair record states that technicians could not reproduce the shuddering during a test drive. A test drive with me was proposed to demonstrate when it occurs. The vehicle has also displayed a “Steering Assist Is Reduced—Drive With Care” warning and a check-engine light. The steering felt normal despite the warning; I am not claiming an actual loss of steering. The temperature gauge has remained on cold, and the air conditioning has malfunctioned. The exact date the steering warning first appeared is UNKNOWN. On October 21, 2026, another Chevrolet dealership documented diagnostic code P0128 and recommended thermostat/coolant-temperature-related repairs. Those repairs have not been performed. The manufacturer was contacted and declined repair assistance. Dealerships have inspected the vehicle; I am not aware of a separate inspection by the manufacturer. I am concerned about the persistent shuddering at highway speeds and the warning of potentially reduced steering assistance. The cause of the shuddering and its relationship, if any, to the other symptoms remain unconfirmed. I still have the vehicle. Repair records, diagnostic information, and photographs of warning messages are available.

What 2019 Cadillac XT5 owners say
Most recent owner complaints, unedited.
The vehicle has approximately 40,000 miles. The thermostat and/or coolant temperature sensor malfunctioned, causing the warning message “Steering Assist Is Reduced, Drive With Care” to appear. This condition raises a safety concern because the malfunction affects or appears to affect the vehicle’s steering-assist system and could make the vehicle more difficult to safely control. I believe this issue warrants investigation by the federal safety agency and consideration for a safety recall.
The computer or electrical box to steer keeps shorting out and the vehicle us unable to turn.
Went to Genesis Cadillac for oil change and they recommended the replacement of both my rear toe links. As stated on their service bill Caused by loose rear toe links. GM has been selectively recalling certain makes, models and model years recalling toe link for replacement. Most recently March 10, 2026 Buick Regals 2012 and 2013. Seems GM is aware of rear toe link issues but doesnt want to have a mass recall. Selects vehicles that are low quantity still driven. Everyone else needs to pay for defective rear toe links Even my brothers 2020 XT5 was recommended to replace rear toe links on his vehicle when he went for an oil change.
The contact owns a 2019 Cadillac XT5. The contact stated that while leaving the driveway, there was an abnormal sound coming from the vehicle. The contact stated that while driving at 65 MPH, there was an abnormally loud squeaking sound coming from the vehicle. The check engine warning light was illuminated. The contact thought that the catalytic converter had been stolen. The vehicle was taken to an independent mechanic who determined that the catalytic converter was severed at the connection point and cracked, and removed. The contact stated that coils were damaged, and the thermostat housing was cracked. The vehicle was repaired, but the failure recurred. The local dealer was contacted, who determined that the catalytic converter had been replaced, but the failure persisted. The dealer informed the contact that the parts were on backorder. The manufacturer was not contacted. The failure mileage was approximately 100,000. The VIN was not available.
We got the message that our steering may be impacted and then our temperature gauge wasn’t working nor the stop/start feature. Trip to service dealer resulted in a $1,186.14 repair for the replacement of the thermostat. This car only has 37,269 miles. We were told by service tech this is a common issue in GM models and this year of car. This was a financial hardship on us and our well maintained, and rarely used, vehicle. How can GM know this is an issue and not offer remedy thru a recall?

The passenger interior side door at the bottom towards the back near the backseat, beginning driver seat caught fire. A small tiny hole began melting, and there was flames coming out of it. Within minutes. My entire car was engulfed in flames when the fire department came they said it seemed like it was fuses that began the Fire. I bought this car used from Carmax literally only two weeks ago and had only driven it. maybe 100 miles it’s a 2020. I don’t understand how this happened and I’m concerned about other Cadillacs of this model having the same issue.
